OK,
I think the problem you are having is caused by doing the ErrorForm stuff on a thread
that is not the main thread. When you do that on .NET 1.1 the app may hang, or the GUI
may fail to behave normally at any time; when you do that on .NET >= 2.0 you will get
an InvalidOperationException mentioning a "cross-thread-violation".
What you need to do is make sure the GUI-related code (that includes everything concerning
ErrorForm) to execute on the GUI thread; that is exactly the purpose of the
Control.InvokeRequired property and the Control.Invoke() method. I also would consider
creating the ErrorForm only once at app initialization, and populating and showing then
hiding it when appropriate (through Invoke).
As I said before, a more recent .NET version helps you in recognizing this kind of
faulty situation long before it causes trouble.

do you think is that why the memory is not freeing up? do you think this is whats causing the whole thing? each time i go from title to title detail it increases the memory by around 5mb and even when i go back it doesn't free the memory up.

I don't know about your memory situation; I do know any app that violates the "every control
should only be accessed by the thread that created it" rule will behave badly, it may
freeze the GUI, hang completely, or (for a while) seem to function normally; whatever the
symptoms, it can not be trusted.
If you violate the rule, first thing to do is fix it. Everything else that remains has
to be handled thereafter.

I'm not really sure about this but try looking in to using the event of KeyPress on you form.
in C# you'd get teh event with something like this.KeyPress+=new K...

I want to learn how to make an application like Shaderman in which we have blocks representing code and which we link together with lines. How are these block build? How are the lines being drawn? Did they use graphics 2d in C# to make the blocks and lines? Where could I find information?

Have you taken a look at what it's written in? Python - I figured that was mockery enough right there.

Hi friends
I have requirement like this.
Let's assume if one form contains more than one data grid which is used to populate different data's.
To identify the grid contents we can use grid caption.
Instead of using the grid caption show the Images in top left corner of data grid.
If any one come across this requirement.
Let me know how you were succeed this requirement

I have a winApplication which has a form.
In that form I have a sql data adapter which contains 4 command for select,update,delete,insert.
When I execute insert command, with passing 9 parameters values, by use of executenonguery function I receive "procedure or function "procedure name" has too many argument specified" error massage at line of executing.
What should I do? I don't know what's happend there cause I check every parameters by breakpoint and saw that every parameters were passed!

You have asked this question already[^]
I have given you suggestions already, including to post the code so we can see it.

And I've told you already that it is obvious that every paramter is passed because the error message tells you that "too many" parameters have been passed. This suggests that you are passing more parameters than was expected.
You have to help us to help you. We can't guess what is in your code. You have to show us.
