is there any logic that without writing code on all the forms to update the button Font Size..
I have taken over support of a VB.Net WinForms application. I am actually a c# developer and am more familiar with the setup of visual studio projects in c# projects. Now I am trying to determine why my application is crashing on a specific XP installation, and I read the suggestion here[URL]..to add a try catch block in the main function. This is suggested in about the 5th post from the bottom. (I will quote it below) However, if I look in the VB.Net visual studio project, I do not find a Main() procedure. What I do find is a grey folder called "My project" with a "Application.myapp" file inside it. This file has an associated designer file, but if I click on it I see the following xml:

My problem is, in fact, I try to follow a recommendation that says: Clipboard.GetDataObject Always Returns null? If you find you're always getting null from GetDataObject, try adding [STAThread] before your static void Main().So, me, if I don't find Main()... I can't follow that recommendation in VB.NET...
We generally have main block to start the program or application first form.I wrote some code in main and it is within try can catch block.Catch block the errors. This try catch block is a global try catch for my whole application.Now if exception occur in the code will be handled in this catch. But Is there any good way to handle the exception in the catch block if occur?as I write error in log file but sometimes file can have permissions for writing etc and it can create exception.As this try catch is the outer most try catch block and if any error occur in that catch it will cause application to crash.

I have a new solution with 5 projects inside. a data access layer, database, 2 class libraries, and the main form. These are all components that I had worked on to get to this point of combining into 1 solution. Now what I have run into is I can not the actual functions in the class libraries. I can get to the class level, but that is it. ere is a sample line of code I need to get working. Once I get this one line, the rest will be obvious: Temperature is on the main form. get for options is "Equals, GetHashCode, GetType", etc... Before this I had bult, compiled, and referenced these classes separately, and it worked fine. I know this is going to be an easy answer, I'm just not seeing it for some reason.

Using vb.net. I've got a main form that displays when application is opened. A popup form can then be opened. If there are other windows opened on the desktop, for example windows explorer, then when the popup form is closed, the main form gets hidden behind windows explorer. You have to move windows explorer out of the way to get to the main form. Is there a way to keep this from happening?

So long, everything works fine in my development machine, which runs windows XP.However, when deploying the application in a windows 7 machine, the message box works correctly, showing itself whenever it should, but after the form is closed the application keeps running in the background. This happens whether the form closes directly or asks the user first.I have fixed it putting an End instruction in the FormBackground.FormClosed event, but it doesn't feel good.

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.
