the parent window should be a pointer to the window/dialog that you are placing the button onto. It is a lot easier to place your button on the dialog in the resource editor. Then use class wizard to add a member variable for the button of type CButton. You can specify in the resource properties for the button that the button uses a bitmap rather than text.

pParentWnd should be equal to "this" if you are creating the button in the window constructor.

The other thing is that passing "1" as the ID of the button may not be a good idea, because all values from 0-99 are reserved for the system. Best Regards,

If you need a pointer to the main frame window of your app call AfxGetMainWnd().....[tt]

CWnd* pParent = ::AfxGetMainWnd();

CWnd* pParent = ::AfxGetMainWnd(); [/tt]

If you simply need a pointer to the window/dialog which will contain a button then you use the [tt]this[/tt] pointer - provided it is being created within the window/dialog class

[tt]myButton.Create(_T("My Button&quot,WS_CHILD|WS_VISIBLE|BS_BITMAP,
CRect(10,10,60,50),this, 1);

When you create a new dialog in the resource editor, if you right-click the mouse VC++ asks you whether you want to create a new class for the dialog. Click Yes and VC++ will create the class and some base code for you.
To display the dialog you would #include the header for this new dialog in some other part of your code and then create an instance of the dialog there:[tt]

// assume dialog created in resource editor and
// class created - the dialog class is called
// MyDialog

#include "MyDialog.h"

void SomeOtherClass::SomeFunction()
{
// create a MyDialog object and display it
MyDialog dlg;
dlg.DoModal();

// to get a pointer to this dialog do this:
CDialog* pDlg = &dlg;
}[/tt]
