• .NET Development Reflection and Structures

  I'm trying to track down any materials, code, books, etc, that cover the topic of dealing with structures via reflection.  This topic appears to be non-existent; nobody talks about it. Just to be clear, By structure I am referring to something akin to the following VB code: Public Structure MyStructure    Public FirstName as String    Public LastName as String    Public IsActive as Boolean End Structure And I am asking for anyone to comment or point me in the right direction where I can find such structures being exposed by Reflection code.  All I have been able to find is cryptic refere ...Show All

Please tell me if there is something else you need to know. ...Show All

• Visual Studio Error Message

  As part of a fairly large project I am working on, there is a web administartion component that has 3 crystal reports that need to be viewed. When I try to click on these reports I get an error message stating: "The report you requested required further information". It also pops up text boxes with server name, database, username, and password with a login button. I am assuming this means that I am not pointed to the right datasource but that's a guess as I am pretty green when it comes to reports. I know that we have it pointing to the right server/db and username/password. If anybody has has experience with this kind of error I w ...Show All

• Windows Forms UpdateAsync() hanging

  In using the example code from MSDN for programmatic update, my code gets to the async call, but fires no events. I changed the async code for checking for an update to synchronous code and it works fine. But then the call to UpdateAsync() fires no events and downloads no bits, even though it knows that there is a new version. The synchronous Update() function works fine, though. Naturally, I want async so that I can get the progress notifications and give my user a progress update during the download. Some code... (splashScreen is a windows form that is open, non-modally, during startup. updateCheckComplete is a boolean flag that I use ...Show All

• Windows Forms Clearing a Formatted DataGridView

  When I try to clear controls and DataviewGrid from a panel which has bound data, it takes several seconds to do it, when I have this line GridHandle.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells If Comment this line then it clears fast.  If comment the above line then it clears faster. Any help would be appreciated. Khalid Mirza mirza@Stellex.com Any changes done to the DataGridView's content -- removing rows for example causes the grid to recompute autosize mode.

  I all community members! I have been using VS2005 B2 for the two month and found it extremely proficient in our development enviroment. I don't know if this thread is in the correct place, but I've been having some difficulty working on a user control designed by another team member, who's also using VS2005 B2.
