You *might* be able to do this using keyboard hooks (look up SetWindowsHookEx at the http://pinvoke.net website), but you really *shouldn't* do this. Those keys are reserved for the operating system; what business does an application have stopping such things?

I have created a login page for my project and it is working fine. After entering the login information and clicking the "Login" button of the first form,
I need to open another form where the user enters the details about his name etc, but I dont know how to activate and pass control to the next form.
Please help me and tell me by which method I will be able to redirect the user to the new form.
Many many thanks in advance.
Regards,
Mini

Response.Redirect is one of the many ways you could do it. Google knows them all.

It is that mythical beast - the 1 with one hundred zeros.

I have got the solution. We can use ..
{....
.....
Form Form2= new Form2();
this.AddOwnedForm(Form2);
Form2.Show();
}
at the point after where we wants the application gets redirected from Form1 to Form2.
have fun

hi,
u can do this using 2 methods.
1. just take one Submit button and change the text as "Login".
in the form tag set the action parameter as the page u want to open when the user click on submit button.
2. just u can use Response.Redirect("Page2.aspx") in submit button click

Google also knows the Server.Transfer() method... shhhh... it's a secret that they hide in the documentation[^].

Jedi should not reveal the secret of our success.

Well, you're obviously dealing with two different datatypes, I'm guessing you want to convert the string to a datetime.

I'm having troubles trying to get my MainMenu component to display in my C# program.
I created my MainMenu object by dragging it from the Windows Form components in the .NET Toolbox onto my main Form. It looks like it is there as it is added in the
"#region Windows Form Designer generated code" area. But when I run the program, the menu items do not display and you cannot click on anything.
Can someone please help me? Thanks in advance.

Every type of object has the method GetHashCode(). I want to learn what the number return by GetHashCode method use by programmers. And is it releated with hash tables

A hash code is used to get a compact value that can be used to efficiently compare large values. A good hash code is created from all data in the value, has an even distribution over the possible hash codes, and shows a large difference in the hash code for a small change in the value.
Hash codes can be used to see if two values are different, which for example is used to compare large files. Even if they only differ by a single bit, their hash codes will be completely different.
Hash codes are used in hashtables to arrange the data so that a key can easily be found using the hash code of the key. To keep the search tree balanced, it's important that the distribution of the hash codes is even.

I have a user control with a panel on it which I paint rectangles and text on using the following method - Graphics mg = this.CallsPanel.CreateGraphics(); When I minimize or switch back and forth between other application windows, I loose the graphics. I have been trying to figure out which event to wire a re-paint function to but am not having much luck. Or, is there a way to anchor the graphics that have been painted until I invalidate and update the panel?

NEVER do this. There is no way to solve the problem you're now having. Draw in your paint event and call Invalidate to force it to occur.

I moved the calls to my re-draw to the paint event for the user control and all is well.
Looks like you gave me what I needed.
Thanks.

Don't just do the re-draw in the Paint event, do all drawing there. Call the Invalidate method of the control when it needs to be redrawn.
Make sure to use the Graphics object that is supplied in the EventArgs for the event, and not create your own.
The supplied Graphics object is clipped to the area that should be redrawn, if you create a new one it won't be clipped, and you might draw on top of someone elses window.

Hi,
/********** Visual Studio 2005, C# .NET 2.0 - Windows Form ***********/
Within my code, I want to hold for certain seconds like Thread.Sleep(2000). But I dont want to block the User Interfaces. Now, I had a choice to use Timer, and When I need to start sleeping, I can call the timer.Start() and use While Loop to check how many seconds passed, if time over then exit the loop, otherwise Application.DoEvents(). But This is a very dirty way and I am looking for an efficient way and I believe there must be some class to do this job. Would you please let me know about that.
Thanks again
Emran.
