Years ago I had seen a tool that when running would allow you to click on a running Winforms application and it would reflect on whatever portion you clicked on to display properties etc of the code. (It saved some time as you could find the exact form/panel/tab etc. that a control lived in) eg. I have a Winforms app with tabs, panels, ...
I have an .net app that seems to have a memory leak issue(s). The .net service starts out around 100MB of memory, but under load it hits around 400-500MB. Most of my classes don't have unmanaged resources, and the ones that do already implement IDisposable. So my question is would slapping IDisposable on my classes help? The 4-500 MB is...

I'm working on a simple vector drawing app in C#/.Net. The drawing is done in a panel, but I'm not using the OnPaint() event for all of it - in fact the OnPaint() even just calls another method which actually draws everything in the document. I tried to add double buffering, but when I set DoubleBuffered to true, the flicker issue is ev...

In VS 2008, when I compile, I get a large series of The class or CssClass value is not defined messages.

Is there any way (in C#) to display a form with just the minimise and maximise buttons? Without the close button? The only way of removing the close button (that I'm aware of) is: form.ControlBox = false; But this also gets rid of both the other buttons. ...

(I know there's some close duplicates out there, but none of them were able to help me, please hear me out) I have the setters of my model throwing appropriate exceptions when something attempts to set an invalid value. This works wonders for validation when the user types a new value. However, when I create a new model object, the ini...
