I have a function to recursively search through windows (and their child windows) to find specific ones, it works exactly as expected, however it causes "function doesn't return a value on all paths" warning. This is the only warning in my entire program, and although it might be silly, I'm interested in knowing if there is a way to stop this error from occurring, but still allowing the function to work properly.[code]

View 3 RepliesI'm trying to use ResolveUrl() to set some paths in the code behind of a custom ASP.NET user control. The user control contains a navigation menu. I'm loading it on a page that's loading a master page.When I call ResolveUrl("~") in my user control it returns "~" instead of the root of the site. When I call it in a page I get the root path as expected. I've stepped through with the debugger and confirmed, ResolveUrl("~") returns "~" in my user control code behind.Is there some other way I should be calling the function in my user control code behind to get the root path of the site?

If I execute any shell command in VB application How can I capture the return code from the shell command. I have written something like this
shell(db2look ....,AppWinStyle.Hide)
Now I want to know the return code of the above command which ran using shell script.
A long time ago, on a PC far, far away from Windows, one MS-DOS program (the father) could run / execute / spawn another MS-DOS program (the son). When the son terminated, it could set a return code which could certainly be interrogated by an MS-DOS batch program or, I think, by any father program that invoked it (depending on the language in which that program was written). I have a small utilility which I want to invoke from my application, and, since that utility sets a return code, I would like to interrogate it in my application when the utility terminates. I've looked through the MSDN Library but could not find anything that seemed to cover this situation. Is there a way to do this in Visual Basic 2008 Express
View 2 RepliesUsing VB 2008 with Access database I'm trying to make a search field (txtSearch), but I'm not getting success with code in the button (cmdSearch). I'm making this manually, not using the Query Builder, and the result will be displayed in a datagridview (added to the form dragging the table from the Datasource Panel). So, the datagrid is already populated (with no SQL). What code must I use for the cmdSearch, to return the txtSearch.Text (or part of it) in the Datagridview? I've tried this: "Select Product, Price, Quantity FROM tblProducts WHERE Product LIKE txtSearch.Text & '*'" (but it doesn't work).

My development machine runs Windows XP, but the target machine runs Windows 2000 with .NET 2.0.I've set my compile options to compile 2.0, which is fine.However, I have some references which are causing issues.For example, Microsoft.Office.Interop.Outlook.dll - in VS2008 the path is shows as the C:Windowsassembly folder which works fine. Until the app is built and run on the target machine and fails:Could not load file or assembly 'Microsoft.Office.Interop.Outlook, Version=12.0.0.0, Culture-neutrl, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.Presumably because on Windows 2000 the assembly folder is C:WINNT.I cannot work out how to target the WINNT folder for my references.

I'm using Visual Basic express 2008.The application I am working on is the first major project I have ever undertook with visual basics. The application is a launcher for a private server for world of warcraft.I have a menu bar that pulls the file path of the wow.exe and puts it in a hidden textbox, I then have another option that saves this text to c:wowexe.txt. All of this works GREAT!
How can I read the .txt file to end and return the information stored in the .txt file to this line of code.
Dim RetVal
RetVal = Shell("This is where I need the data from the .txt file to be seen", 1)
If your wondering why I don't just type in the path of the .exe, it's simple, not everyone installs World of Warcraft on the C drive.
