VWD 2008 Express. Visual Basic.I have a customvalidator on my page and a corresponding OnServerValidate routine tied to this control in my VB code behind. I also have a "Save" button that is defined as "CausesValidation=True." I placed a breakpoint in my OnServerValidate code for the customvalidator and a breakpoint in my OnClick routine for the Save button. What I expect to happen is that when the "Save" button is pressed, all the validation is checked before ever entering the OnClick code for the Save button. If any of the validators are false, then I expect that the Save button OnClick code will not run.

View 4 RepliesI am looking into writing a web-based vehicle tracking system. The framework I have in mind looks something like this:
Client application --- Database --- Database updater.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages? Any pointers to relevant technologies?

I am completely new to ASP.NET programming, and was asked to work on a small project involving ASP.NET, VB (which I am new to as well) and Microsoft SQL Server 2005.
Being used to php/java I was hoping to find some kind of similar API to php.net and the javadoc. It would be very useful to have as I would prefer to work with a text editor, instead of using DreamWeaver or Visual Web Developer.
In the project I basically only need to use ASP.NET to read from a SQL 2005 database and write to JSON files.
I have some project written in Visual Basic (not Visual Basic .NET but simple Visual Basic - sic!). I can compile it and generate a dll. Then inside my web application I add reference to this dll library. When I run my web application hosted in default Visual Studio server, everything is fine and I can debug my Visual Basic project. However, when I host my web application in IIS then I can't. Code does not stop in my breakpoint. My asp.net catch the exception when I try to execute some method from the mentioned library which is something like:
Unable to cast COM object of type 'xxx' to interface type 'yyy'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{4C2875B5-3265-306B-9C74-1BEC98986B1A}' failed due to the following error: Error loading type library/DLL.

View 3 RepliesI just upgraded to VWD 2010 Express and have a couple of questions:
1. How do you disable "code-behind" when creating a new project? It seems that "code-behind" is set by default. My previous projects written with VWD2008 Express use the opposite ie. the "code inside the page" approach. What options should I change?
2. When using the non "code-behind" model, the drop-down showing all page controls and their associated events is missing in my configuration. In VWDD2008, this list sits on the top of the editor. Any idea how I can restore the control list?

Is there a way to delete an entire gridview with code?

I would like to completely delete it and create it anew based on the new selection.
View 4 RepliesFor my Dynamic Data site I have a table that has a join to a number of other tables. If I use the standard page for this table I get all of my columns from the primary table and related tables (which is good) and the appropriate literal values from the related table (which is great). The bad part is the order of the columns.
To address the order of the columns I created Custom Folder/Page for the table. I also have a partial class that controls date formatting. This takes care of the ordering of columns fine (which is a step forwared), but now I'm seeing the foreign key IDs instead of the literal values from related tables (which is a step backward).
All I did was copy the standard page to the Custom folder for the table, turn off AutoGenerateColumns, and specify the column order and display name. Why would the foreign key change occur? As a side note, if addressing column order in the partial class is the preferred method I could go that route, but I haven't been able to understand how to do that in VB (I've seen many examples in C#, but that's not my strong point).
I am trying to figure out what are the basic assemblies required to run a basic ASP.NET 4.0 website. Say.. a website with just a label in it. I looked online and didn't find a list there. I know installing the framework 4.0 will give me all the dlls but I just need the basic ones that will make a basic site work on ASP.NET 4.0.
