yes,my CAboutDlg is derved from CPropertyPage!!
hi

It sounds to me that you are calling this function before the window has been created.
The exception you get is probably about the hWnd being 0.
From where are you calling this?
What function?

You can handle WM_CLOSE message or you can write the code on the button click which you are using to close the dialog.

You can call GetCommandLine to get the command line which was used to launch an application.

Could you please tell that where I can use "GetCommandLine" in dialoged based application.
any sample?
Thanks again
Regards.
|
|
|
|

This will show the command line in a message box:
AfxMessageBox(GetCommandLine());
Another options is the following:
AfxMessageBox(AfxGetApp()->m_lpCmdLine);
Both these options produce slightly different results so try both and see which one's right for you.

It means I can use these at any place in the Application. ?
As I was thinking may be it is only workable in CDlgApp class
Regards.
|
|
|
|
|
Yeah, you can use them pretty much anywhere in the application.

try _ _ argv and _ _ argc. (Underscore are continuous, I have separated them to improve readability)

I am working with the serpent encryption algorithm for the first time, and I wish I could find a tutorial on programming with serpent. Also, I am not going out and buying a book on serpent for this current project. I think I am just missing something simple, but I am not sure what.
When I call the serpent encryption code:
Serpent::Encryption();
I get the following errors:
'Serpent' is not a class or a namespace name
'Encryption' identifier not found
Hopefully someone knows what I am doing wrong.
Thanks.
btw, I am programming in .net

It looks like you're not including the header file which contains Serpent's function declarations and class definitions.
Steve
|
|
|
|
|
using:
#include <Serpent.h>
which includes:
typedef Serpent::Encryption Serpentencryption<br />
typedef Serpend::Decryption Serpentdecryption
ps. Thanks for the help
