Windows application and low resolution?

I have a Windows application developed in VS.Net 2002 and upgraded to
VS2005, and when I try to run it in an 800x600 resolution, it doesn't load
completely (plus its memory usage is really high). If I minimize, and
maximize it, then it'll display correctly.
How come? Is there a fix?

Thanks.

That doesn't happen normally. So your application does something
unusual that depends on the resolution somehow. If you can post a
concise-but-complete sample of code that reliably reproduces the
problem, someone might have a suggestion for how to fix it.

Otherwise, the chances are relatively low that someone can answer your
question.

Hi Doc,

Could you tell me in what screen resolution the application was developed,
800x600, 1024x768, or something else?

Do you have code to "relocate" the controls on the form in the application?
Otherwise, the controls on the form shouldn't display correctly after you
minimize and then maximize the form, if they don't display properly when
the application is run.

The application was developed in 1024x768. The problem is that the
application doesn't completely load when the resolution is 800x600. It
seems to freeze when it loads in low resolutions. The Forms are half-drawn
(it also freezes). Not only that, but while it's loading, the process uses
100% CPU. The only way to "fix" it is to minimize it (and let Windows draw
the Forms in that state), and maximize it.
Thanks.
 
Thanks for the help.

The problem (or part of the problem) is that the MDI Form has a tabcontrol
docked to the left, so if the application loads at 800x600, the Tab Control
automatically resizes and "hides" to the left. This resizing while loading
was causing this problem. I eliminated this and the application loads
correctly.

So it's not possible to do this at such low resolutions?

Thanks.
 
Hi Doc,

Thank you for your reply and more detailed information.

I performed a test based on your description.

1. Under the 1024x768 screen resolution, I create a WinForm application
project which has a form with a TabControl docked to the left side and the
form's size is 1024x700.

2. Build the project.

3. Run the application under the 800x600 screen resolution and the size of
the form becomes 812x612 when it is shown. Part of form falls outside of
the display area of screen.

4. Memory usage doesn't become higher when application is run under 800x600
screen resolution.

To ensure your form to be shown properly under any screen resolution, I
suggest that you set the WindowState property of the form to Maximized.

Hope this helps.
