When I run the app on my machine everything works perfect. But when I run it on another machine, the following error appears:

Also a memory problem must be out of the question. I only use 300mb from the 4GB. There is also enough disk space available.

View 3 RepliesI retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?

I have designed a complaints form for my work (free of charge just for my cv). I designed the form for the resolution 1280 x 1024. My problem is when a user with a smaller resolution say 800 x 600 uses it. The form will be out of sync with the screen as shown below (tested on my on computer). So I am wondering is there a way to test the screen size of the users computer then readjust the size of my controls according to the size of the screen. By the way all of my controls are anchored so that they stay in the same place.

Have you any links or ideas, or experiences, what is to be done to class derived from System.ComponentModel.Component, in order to show its rectangle in designed form or control. I maybe satified with just making Component shapy. Anything else should be just game. But actually I have no idea how to draw component from its basics. Any idea or link, or bunch of links very welcomed! Even my capabilities of crunching google links are nothing here.
