Use GetFocus() which returns the CWnd* object which currently has focus...

So you can compare likewise...

bool <code>CYourMainWindow</code>::IsFocussed()
{
   return GetFocus()->GetSafeHwnd() == this->GetSafeHwnd();
}

Don't compare CWnd* values to tell if they are the same window. Call GetSafeHwnd() on both and compare the HWNDs.

Hello All,

I have just build my windows app. to send a specific https request. At runtime it shows error code 12002 which is related to the request timeout I think.

Hi all,

I want to know whether a function exists that can invoke a messagebox with a editbox inside of it (From a WIN32 console application / without using MFC)??
Makes sense ?

Thanks

Hi,
Better u add one more dialog with an edit box in it. Make it as a child, then you can use it just like MessageBox by calling the dialog in appropriate places.

CMyDialog *dlg = new CMyDialog();
dlg->Create(IDD_DIALOG1, NULL);
dlg->ShowWindow(SW_SHOW);

use this in places where you would like to call the MessageBox.

Regards,
Syam.

You'd have to use at least Win32 to get what you want.

Yes, that is MFC.

Well, MFC is a class library implemented in C++ that wraps the Win32 API, so technically it is an answer to your question.

But, I guess your question is how you can do this in C/C++ without the MFC library.
If this is the case, the answer is you have to use the Win32 API directly, e.g. DialogBox[^] for showing a modal dialog box.
Have a look at the CP - Win32 section here[^] to see if you can something that may help you.

Change CDialog Style

16-Apr-07 23:28

Hi,

i use a DialogRessource for a view, so the style must be "subordinated", with this style
the Dialog has no Border and "works as a View"

Now, i use to make a Dialog Window (Modal State), i derived a CDialog class with the same IDD
of the Dialog which i used for the view.

All works nice, but the Dialog has no Border (titleline,Frame,...)
Because i set the style to "subordinated"

How can i change this style at runtime? (At the creation)

Thanks in advance Smile | :)

I'm wanting to be able to accept electronic payments for consulting and products through a service like PayPal. However, I'm not entirely happy with PayPal (their fees seem high and takes time to get them to pay you), and want to explore other options.

Anyone have thoughts?
