In my form, I have 8 textboxes. All of these need to be filled in, and I wanted to check if they are filled in before going to run the rest of the code. The only way I've done it thus far is 8 nested IF statements, and this looks unorganised and seems like a horrible way to do it. Can someone tell me a better way to do this? If there i...

I'm drawing images on panel controls. Changing zoom factor changes the size of panel control (which should stretch the image accordingly). With zoom factors greater then 1 (ie, 2,4,8) a small part of panel begins to show (testing shows that it is the background color of the panel) and grows along with the zoom factor. Panel control bor...

What I mean by that is: With Winforms, a fine-granularity usually works quite well for user controls. That way, it's easy to reuse user controls and use them as building b...

On XP, the dialog displays a "Printer..." button which allows the user to select a printer and select from a list of page sizes supported by only that printer. On Vista, the very same code displays the dialog without any butt...
If I turn off automatic updating of a binding data source by setting DataSourceUpdateMode = Never and then use a button to update the whole lot (using binding.WriteValue), a problem occurs - Namely, only the first bound control's data source is updated. All other controls are reset back to the original values. This is because when the c...
