• Visual Basic How do I know if an exception is thrown from a specific method?

  Hi, I am relatively new to VB .NET. (I have started using .NET v2.0) I have a Class that does some work with a Dataset and if an Exception occurs, I catch it and throw it again so that the calling method from the GUI can catch it and throw a custom message. I would like to ask you if there is a generic way to define which exceptions the method might throw. That way when I write the code of the GUI that calls some methods of some classes I will not have to go back to each individual method, search the code and find what exceptions it throws in order to catch them and display custom error messages. For example in Java you can decl ...Show All

• Visual Studio Express Editions Icons for my Application????

This may seem obivious or silly to some- but how do I control what icon windows uses for my application when veiwed in an explorer window Is this even do-able in VC++ Exp Ed I've tried the form icon field in Designer, but that only seems to set the icon for the taskbar. Again, any help would be greatly appreciated. Cherrs DT. If you created the project from the templates, they will have created a file called app.ico (or possibly <app>.ico) in your directory.

• Visual Studio Team System TFS Install fails...

  I installed TFS Beta 2 on a new Win2k3 server, pretty fresh install. Nothing really running on it yet except SQL 2005 with default setup. The installation got almost to the end... like .1% left, and froze for several minutes then returned an error that a service or something wasn't responding - Retry or Cancel. Retried a few times, same error. Cancelled, the installation "finished" and then crashed. There is no sign that TFS is actually installed except a few empty folders in Program Files. Now I cannot run setup again because it says TFS is already installed, but I can't uninstall it because from all appearances on the system, it is no ...Show All

• Smart Device Development Loading images as embedded resource: How to optimize

  Hi!!! I have a pda application that uses a dll that I made. That dll has some images that i load as an embedded resource, when i run the application, it takes some time t load all images and i can see in the emulator the images loading... What can I do to make the images load at the same time Thanks in advance A useful method of determining the full name of all embedded resources in your assembly is to use GetManifestResourceNames which returns an array of strings containing each resource filename e.g. string[] resourceNames = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames() ...Show All

• Windows Forms Refresh Designer at Design Time?

  Hi,   I’ve created a simple user control which resizes its height automatically according to the image size loaded by a user at design time. After loading the image my control resizes but the control selection area doesn’t resize automatically - only when I click on the control. My control also has a custom control designer which restricts the control user to set the user controls height at design time.     Is there any particular reason why this is happening How can I fix this   Thank you, Eric Maroudas.
