Hello yogita ,
It depands on your working scenerio.
If its just class with some methods to call then I suggest to Create instance in every aspx but please dispose that object too.
If that class contains session or user information then you may use in global class.
Thank You.

Hi, I'm wondering how I can remove the 'Close' button on a modal dialog. The reason is I don't want the user to accidentally close this partiulcar window, or at least display a confirmation to the user to ask whether if they really want to close it. I can't do that with the Form_Closing event as it stills closes it.

write your code int Dispose Method.e.g
protected override void Dispose( bool disposing )<br />
{<br />
<br />
if(DialogResult.Yes==MessageBox.Show("Do you Want to quit?","Quit",MessageBoxButtons.YesNo))<br />
{<br />
if( disposing )<br />
{<br />
if(components != null)<br />
{<br />
components.Dispose();<br />
}<br />
}<br />
base.Dispose( disposing );<br />
}<br />
else<br />
return;<br />
}<br />

When the Form is getting disposed it is already closed. So this doesn't work. Dispose is about freeing resources - no more no less.

Hi,
why can't you do this with the Closing event? This is exactly what it is meant for. Post some code. You have most probably some mistake in your code.

Robert, I don’t want say this but I have to say Check your Premise

|
|
|

Hi,
even after looking in a dictionary about premise I don't really get what you want to say. May be my mistake because english is not my native language. Could you reformulate?

You can. If the user doesn't want to close the form, assign true to the Cancel property of the passed CancelEventArgs instance.

I have a Main Form call FormA, FormA call a Lookup Form named FormB using following Code
<br />
FormB formb = new FormB();<br />
FormB.Show();<br />
in FormB there is a textboxA to let the user to enter certain string value that need to passback to FormA and execute several statements in FormA when user press a button in FormB
Any1 has any idea how to do that?my fren advise me to use delegate but i not very familiar with delegate coding structure, i greatly appreciated if any1 can provide the sample coding to do that;)

There are many ways to accomplish your task.
1) Best way would be to make a custom event. As you told that you dont know much about delegates so I think it will be even difficult for you.
2) Make a static method in FormA and call it from FormB's click event handler by either passing it this (FormB object) as an argument if FormB is not class variable in FormA. In that method get all the values from FormB and then you could just close FormB or even destroy it.
3)In the click event handler of FormB, get its Parent by FormB.Parent, this will yeild you the reference to FormA's object. Now you could do anything with it.
You can use any of the above mentioned way. Hope it helps.

Thanks man, i am trying the method u suggest

Hi every body,
I have to call a DLL that contain a function follow:
typedef struct _ProStruct {
HANDLE hProcess;
HANDLE hThread;
DWORD dwProcessId;
DWORD dwThreadId;
} ProStruct
int MyBuggingFunc(long bDebugMode,ProStruct* pProStruct,TCHAR* Location);
When I call it in C# 2005 such as:
public struct ProStruct{
long hProcess;
long hThread;
int dwProcessId;
int dwThreadId;
}
[DllImport("MyBugFunc.dll",CallingConvention = CallingConvention.Cdecl)]
public static extern int MyBuggingFunc(int bDebugMode,
ProStruct pProStruct,String Location);
private void Form1_Load(object sender, EventArgs e)
{
try
{
ProStruct pPI = new ProStruct();
int ret = MyBuggingFunc((int)(1), pPI, "MyTest.dkt");
}
catch (Exception loi)
{
MessageBox.Show(loi.Message);
}
}
When the form is loaded, there is an error occurs:
"PInvokeStackImbalance was detected
Message: A call to PInvoke function 'WindowsApplication4!WindowsApplication4.Form1::MyBuggingFunc has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
"
I assume some parameters have incorrect type with convention in calling DLL from third party DLL. I tried to fix it many times but I get the the same error.
Could you help me to resolve my problem?
Thanks all of you!

Your long types are what's wrong. In C++, long is 32-bits long. In C#, long is an alias for System.Int64, which is 64 bits long.
Try this:
public struct ProStruct{
int hProcess;
int hThread;
int dwProcessId;
int dwThreadId;
}

Thank you very much.
I've tried to fix my problem as you shown but the same error uccurs.
Can you have any ideals to help me?
Thanks again!

public struct ProStruct{int hProcess;int hThread;int dwProcessId;int dwThreadId;}
Thank you very much.
But I've tried it before but the same error occurs.
Could you have any other ways?
Thanks
