How will my site render on all browsers?

2009-12-02T21:29:00.000-05:00

I recently was browsing the Mozilla Tools listing, and I cam across another amazing tool created by Adobe called BrowserLab. Browserlab allows you to view any publicly viewable webpage as it would be seen by Firefox (OSX & XP v. 2,3,3.5) Chrome (XP v. 3), IE (XP v. 6,7,8) and Safari (OSX v. 3,4). You can overlay each browser view to see differences, as well as use a rule to measure positioning of elements on page. Check it out! BrowserLab (You have to create an Adobe account, which takes 10 seconds...just do it)

Mono Visual Studio Plugin

2009-11-12T20:57:00.000-05:00

Ars has a great article on the up and coming visual studio plugin which will allow .NET developers to build code locally, deploy it to a Linux server, and debug the code executing (via Mono) on the Linux server. Has anyone out there made the jump to building apps on their Linux machine with Mono? Pros/Cons?

Azure Storage Manager

2009-11-11T21:48:00.001-05:00

It looks like Cerebrata has created a useful web app for Azure developers. You can visualize your data (Tables, Queues, Blobs) in a great Silverlight interface. You will have to enter your storage account unique name, and Account shared key, but they once you logout, Cerebrata does not keep record of your account info. Check it out! https://onlinedemo.cerebrata.com/Cerebrata.CloudStorage/default.aspx

SQL Azure Team blog just announced that the R2 release of SSMS 2008 includes features to access SQL Azure in the cloud! Download is currently available for Technet and MSDN subscribers.

Use thunderbird to Transfer gmail email

2009-08-08T23:16:00.000-04:00

I recently made the decision to switch from one gmail account to another. The former was created in college and was more for fun than future use. The second one I created is more appropriately named and professionally sounding. Anyhow, I wanted to transfer all email from one gmail account to the next. There was not a clearly defined way to do this, so I had to hunt around the interwebs to find a solution for myself. Here are the steps I took:

Enable IMAP in both your old and new gmail email accounts.
Download Thunderbird.
Add your old gmail email account to Thunderbird with IMAP protocol options.
Add your new gmail email account to Thunderbird.
In your old gmail email account, expand the [Gmail] folder to view the IMAP folders for your gmail account.
Select the email messages you want to copy to your new gmail account.
Right Click >> Copy To >> new gmail account >> [Gmail] >> whatever location you want the email to be copied to (Inbox, Sent, All Mail)

Let Thunderbird work it's magic. Depending on how many messages you are copying and their size, it can take a while. Thunderbird will download the entire message locally and then copy it to the destination. Hope this helps! -Dave

DataItem Dag-Nabbit!

2009-08-06T18:56:00.005-04:00

Recently I was faced with the issue of trying to get multiple data columns from a DataGrid row during the event raised from a link button inside of a TemplatedColumn. When the link button was clicked, I was not able to access the selected item's DataItem. I had to find a work around. Microsoft does not allow access to the selected item's DataItem except during runtime using reflection. But, I needed to access the data item somehow so I created a workaround. Here is my original code:


                    
                        
                            
                                
                            
                        
                        other column 1
                        other column 2
                        other column 3

protected void cmdUpdateContractID_Command(object sender, CommandEventArgs e)
        {
            DateTime RunDate = Convert.ToDateTime(e.CommandArgument.ToString());
            String RunSeq = e.CommandName.ToString();
        }

I wanted to be able to access the data from the other BoundColumns. So, I used an expression on my aspx page, and a custom method in the code behind to get around the DataItem lifecycle issue:


                    
                        
                            
                                
                            
                        
                        other column 1
                        other column 2
                        other column 3

protected string GenerateArgString(object dataItem)
        {
            StringBuilder args = new StringBuilder();
            args.AppendFormat("{0}|", 
                 Convert.ToString(DataBinder.Eval(dataItem, "FIELD_1")));
            args.AppendFormat("{0}|", 
                 Convert.ToString(DataBinder.Eval(dataItem, "FIELD_2")));
            args.AppendFormat("{0}|", 
                 Convert.ToString(DataBinder.Eval(dataItem, "FIELD_3")));
            args.AppendFormat("{0}|", 
                 Convert.ToString(DataBinder.Eval(dataItem, "FIELD_4")));

            return args.ToString();
        }

You can see that I added the CommandArgument attribute to my Linkbutton, which in turn allowed me to generate a string of pipe delimited values from the selected item's DataItem. The expression calls the GenerateArgString method, which evaluates the DataItem using DataBinder.Eval method to retrieve information by column name.

Hello All! It has been quite a while since I have posted. I have been learning a little something called Java as well as taking some classes and have not had the opportunity to post. Anyhow, I came across some cool info about HTML 5. Canvas, video, Cache, Web Worker....some pretty cool stuff. You can check out some demos here but you will need an HTML 5 compliant browser. (such as Google Chrome). All the demos are done using client side html...no applets, flash or silverlight shenanigans. Enjoy the future of web development! -Dave Reference

the vast pool of knowledge

2009-01-06T18:18:00.002-05:00

I read an article entitled "21st Century Mindset" recently and caught glimpse of this quote, and thought it would be appropriate to share.

Networking has changed our relationship with knowledge, making it accessible anytime, any place, on any device. Too little knowledge is no longer the challenge; sifting through the vast pool of knowledge, analyzing it, and collaborating to solve problems is the new dilemma.

I have had my fair share of information overload on the internet, and I never feel at a loss for not being able to find information. However, I do admit that there is difficulty in being able to "sift through the vast pool of knowledge" and come to a conclusion. Just a thought...

CSS Color Scheme generator for the color-blind

2008-11-26T08:42:00.001-05:00

Recently while building a sample site with Windows Azure, I found myself trying to determine the color scheme for my site. I determined that my lack of color coordination was stopping any real progress, so I went to Color Hunter to develop a color scheme for use on my site.

There are two key features that I found helpful

You can choose from other popular color schemes
You can upload your own picture and Color Hunter will extract the colors from the image and give you the matching colors.

If you have a minute, check it out. It is really cool and helped me sail through my CSS design phase.

Windows Azure Developer Starter Guide

2008-11-24T10:40:00.001-05:00

Recently, I started to look into development on the Windows Azure CTP platform with the release of the SDK. I am going to write a developers guide to getting started with Azure CTP. Let’s get started!

Software Requirements:
- Vista or Server 2008
- Visual Studio 2008 SP1 or VS Web Express Version
- SQL Express 2005 or 2008 (if you already have a full version of SQL Server running, you must install Express as a new instance.
- .NET 3.5 SP1
Once you have all the required software on your machine, you need to install the SDK and the VS plug-in. The plug-in adds a project template to VS so that you can create a project with the appropriate web and worker roles.
The SDK installs two main working components: The development storage service and the Azure fabric. These two components have UI monitoring tools that allow you to view process/tracing information and service statuses. You can manually start these services by going to your Start menu > Programs > Windows Azure SDK (but for the sake of this tutorial, wait until the next step to start the services).
To start up your local Azure fabric and development storage, navigate to and execute the batch file ~/Program Files/Windows Azure SDK/Samples/RunDevStore.cmd . This will build your sample projects, start the Azure fabric and dev storage and create the appropriate storage structure. You can start one of the apps from the command line by navigating to the root folder of an app (ex. HelloWorld) and executing the runme.cmd file.
Lets code (dave code)! Open Visual Studio (as Administrator) and create a new project:
- select Cloud Services from the Visual C# project type
- In the Templates list, select Web Cloud Service. This creates a web role. This web role handles http requests and serves up ASP. NET pages. If you choose the template that has both web and worker role, you will see the worker role is added. This worker role acts as a service running locally that can interact with the development storage, role manager, etc.
- In your project, open up Default.aspx and change some text. Hit F5 and you will see your changes in the browser.
- Storage Client Library: Open up the sample project title Storage Client Library, you will notice that there is a whole library of classes and methods for interacting with the development storage. If you add this project to your solution you can debug through and see how it works. You can utilized the exposed classes to write your own Azure apps. See the SDK sample apps for examples on how to use the Storage Client Library. (This library is based on the ADO.NET data services. If you have had experience with ADO.NET, you may have dealt with DataServiceContext class. If you are interested in looking at the plumbing of the Storage Client Library, you will see plenty of ADO.NET classes leveraged.)

I hope this tutorial has been helpful for you. Please drop me a line if you have any questions about getting started.

How to read disk drive information using C#

2008-10-09T16:09:00.001-04:00

I just came across some cool C# code while preparing for the Microsoft 70-536 exam. Using the Windows Management Instrumentation (WMI), you can inspect a machine for available disk drives. Add the System.Management assembly as a reference in your project, and off you go:

ManagementScope DemoScope=new ManagementScope("\\\\enter_machine_name_here\\root\\cimv2");
ObjectQuery DemoQuery = new ObjectQuery("SELECT Size, Name FROM Win32_LogicalDisk WHERE DriveType=3");
ManagementObjectSearcher DemoSearcher = new ManagementObjectSearcher(DemoScope, DemoQuery);
ManagementObjectCollection AllObjects = DemoSearcher.Get();
foreach (ManagementObject DemoObject in AllObjects)
{
Console.WriteLine("Resource Name:" + DemoObject["Name"].ToString());
Console.WriteLine("Resource Size:" + DemoObject["Size"].ToString());
}
Console.Read();

Where does my stuff come from?

If you have ever wondered where the casing from your cell phone was made, or how much of an impact throwing away a juice box makes on environment, this video is for you. I found Story of Stuff linked on Damien Rice’s MySpace page. The website shows a very well done video explanation of where “stuff” comes from. Not only where it comes from, but we should think twice about using that stuff.

SPOILER WARNING: This video is not a I-feel-so-guilty-I-am-going-to-live-in-a-shack-in-the-woods kind of presentation. It was produced to let everyday people know that there is a story behind our large amounts of stuff. It does not just appear magically on the shelves at Kroger.

Lessons in managing (from a developers prospective)

2008-07-14T16:40:00.001-04:00

If you are feeling stressed about the deadline of your project, it is natural to feel the urge to crack the whip and be on your teammates backs. However, after my recent experience in which I was responsible for making sure our code was delivered on time, I have learned that micro-managing others is not a good approach.

If you are a developer, it is more than likely you know the feeling of having someone watching your every move. I don't know about others, but I don't like it. As a professional, I make every effort to make the most of my time. Having someone telling me to work faster only works the first two or three time....then it becomes bothersome.

So, if you are feeling like you are becoming "that guy" who is micromanaging your employees, try to re-align your outlook with these few guidelines*

Challenge yourself to find a 20/80 balance. Use 20% of your time to manage others, and 80% of your time to accomplish your tasks. Take the focus off of making sure your employees are completing your work, and make sure you complete yours!
Communicate your concerns/fears to your superior. If you are feeling too stressed out to deal with all the issues/blocks, or you don't think you can meet the deadline: TALK TO YOUR SUPERIOR! It is their job to make sure you get your job done.
Following my previous point, don't release your frustration on those below you. Release your burdens upwards, not downward. Those below you will just feel depressed if you unload on them. Those above you can actually help you overcome those issues.

I hope you find this helpful!

IE (5.5,6,7,8) version testing de-mystified

2008-06-16T14:18:00.000-04:00

As a result of recently passing the 70-528 exam, I decided to start sharing my vast knowledge of ASP.NET with the world (ha). Ok, so really I just wanted to test my abilities by responding to some forum posts on www.asp.net/forums. I have made some good suggestions (IMO) and have sent some links to people with some ideas on how to overcome their problem.

One post that I made recently was in regards to a question about how to best test different versions of IE when dealing with UI issues, such as CSS and javascript. I posted some links about some solutions I have come up with over my 2 years of web development.

IE 6 VPC: This is a great tool for any developer who already utilizes Microsoft Virtual PC 2007. As we all know, you cannot install two versions of IE on your machine at once. But, if you have two instances of WinXP running on your machine, you can have a different version in each one! Once you have MS VPC 2007 installed, you can run the VPC on your local machine, and test your web app with both your local machines version of IE(7 or 8), and the VPC (IE6)
Download Virtual HD here.
IE Developer Toolbar & IE7PRO: If you are running IE7 and want to see the DOM, CSS, javascript, generated source, etc, then you need to download these tools. IE Developer Toolbar was developer for IE by the IE team. This tool allows you to click on UI elements, and see source HTML information. You can navigate through the dom visually and do a lot of other cool things. The other tool is IE7Pro. It allows you to have many useful pieces of functionality that you don't get from IE7 out of the box. Improved tabbed browsing functionality, view generated source, and many more useful features that you might miss if you have been using Firefox recently.
IETesterThis tool shows a side by side comparison of how a web page renders. You can choose the rendering engines all the way back to IE5.5 up to the new beta IE8. If you use this tool extensively, send me your feedback as I am curious to hear what others think of it.
Download IE Tester Here

Ok, that is about it for IE testing utilities. Hope this helps you out!

Geek Speak > Not as cool as you may think

2008-04-08T11:03:00.002-04:00

I came across this article today on Google Reader. It teaches a great lesson for any deveoper who interacts directly with non-technical users/clients.

Much like the elusive African dancing monkey who does a fantastic version of the Electric Slide to confuse their natural enemies; developers have the ability to sway entire debates in their favor by confusing their enemies with technical jargon. After all, who can argue with someone when they have no clue what the other person is talking about?

Save server memory with Response.TransmitFile()

2008-02-25T12:19:00.016-05:00

So, two common tasks that I encounter when sending files to the browser:

Open file within the browser
Open "file download" dialog box

I used to use the Response.Write() method, but recently came across the Response.TransmitFile() method. This method directly writes the file to the HTTP response stream and saves you from hogging up memory on the server.

1) Open file within the browser

Response.ContentType = "application/pdf";
//write file to the browser without saving file in server memory
Response.TransmitFile("c:\docs\pdfs\test1_1.pdf");
Response.End();

2) Open "file download" dialog box

Response.ContentType = "application/pdf";
//add 'attachment' header to open 'file download' dialog box
Response.AddHeader("content-disposition", "attachment; filename=test1_1.pdf");
//write file to the browser without saving file in server memory
Response.TransmitFile("c:\docs\pdfs\test1_1.pdf");
Response.End();

Some other types of "write" methods that exist in the System.Web.HttpResponse class are

BinaryWrite()- use this method to output a file that is stored in a Base64 string format
```
Response.BinaryWrite(Convert.FromBase64String(EncodedDocument));
```
WriteFile()-use this method if you desire for the file to be stored in memory, or if the file is already in memory. This method is expensive because it stores the file object in memory, then transmits to the client.
Write() -there are a few overloads for the type of objects that Write() can send to the client. It is a flexible method and TransmitFile() or BinaryWrite() may better fit your specific needs

Change Master Page styles based upon the current page

2008-01-22T13:04:00.000-05:00

In ASP.NET, a common practice is to create a master page, and expose content regions to the .aspx pages to hold page-specific content. One way that you can dynamically change the Masterpage content (i.e. add/remove asp controls, change style values) is to determine the actual page name (xyz.aspx) that is going to be displayed.

string filePath = Context.Request.FilePath;
string pageName = filePath.Substring(filePath.LastIndexOf('/') + 1);
//pageName will now hold the name of the file requested

Once we figure out which page is being requested, we can handle the behavior.

For example, if the page "NoBorderTables.aspx" should set all the tables to have no border, you can execute some code like this:

 protected void Page_Load(object sender, EventArgs e)
        {
            
            if(!IsPostBack)
            {
                string filePath = Context.Request.FilePath;
                string pageName = filePath.Substring(filePath.LastIndexOf('/') + 1);
                
                switch(pageName.ToLower())
                {
                    case "NoBorderTables.aspx":
                         foreach (Table t in this.Page.Controls)
                         {
                           t.BorderStyle = BorderStyle.None;
                         }
                         break;
                 )
             )
         }

Gridview - Delete a row

2008-01-18T10:28:00.000-05:00

So, I recently developed an ASP:Gridview to display a list of documents. I was having some problems accessing the datakey of the row that the "delete" button resided in. I looked around a bit, and I found a resolution on the asp.net forums. It turns out that the GridViewDeleteEventArgs object contains the current row index. The DataKeys of the gridview are stored in the same order of the row indexes. You can access the DataKey (which in my case was the document ID number) by getting the GridView.DataKeys[e.RowIndex].

Codebehind event handler for when "delete" button is clicked notice how the event handler event args type is set to "GridViewDeleteEventArgs"

protected void DeleteDocument(object sender, GridViewDeleteEventArgs e)
{         

        int DocID = Convert.ToInt32(this.ListOfDocumentsGridview.DataKeys[e.RowIndex].Value);

        Document.DeleteByID(DocID);

}

C# ternary if

2008-01-14T14:56:00.000-05:00

Just to get some exposure for pretty specific searches, I wanted to give some examples of the ternary "if" statement in C#: If you would like to set a variable by an "if...else" condition, it can be done with the ternary if statement. (Notice I am also using the new .NET 3.5 "var" to declare my variable). In the example below, I want to see if I am old enough (25 yrs old) to rent a car without the "underage" fee. Is today 25 years or more from my date of birth:

DateTime myBDay = "02/08/1982";
var AmIOldEnough = DateTime.Today >= myBDay.AddYears(25) ? true : false;
