BOOL CDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN && (pMsg->wParam == VK_RETURN))
{
pMsg->wParam = VK_TAB;

One simple method is to get the controlId from pMsg->hwnd by using GetDlgCtrlID() and check whether its that of your button control. See the code snippet rewritten for you. Roll eyes | :rolleyes:

BOOL CDlg::PreTranslateMessage(MSG* pMsg) 
{
    if (pMsg->message == WM_KEYDOWN && (pMsg->wParam == VK_RETURN))
    {
        // Get dialog item id.
        UINT CtrlID = ::GetDlgCtrlID( pMsg->hwnd );

        // Check whether its that of your button.
        if( CtrlID != IDC_BUTTON1 &&
            CtrlID != IDC_BUTTON2 )
        {
            // If not modify VK_RETURN as VK_TAB.
            pMsg->wParam = VK_TAB;
        }
    }
	
	return CDialog::PreTranslateMessage(pMsg);
}

I am creating DB application using VC++ & MS Access.

To store D.O.B. to MS Access DB, in VC++ dialog which control is good, is Date Time Picker useful?

Thanks,

When getting the resources of type RT_RCDATA loaded into memory, MSDN is clear that the memory will be automatically released when the application terminates, but it does not really provide a way to release the memory when we are finished with it.

I can't use GlobalFree() and UnlockResource() is deprecated.

Any ideas on how to explicitly release the memory that the pointer returned from LockResource points to?

I found some code that went :-

HGLOBAL hGl=LoadResource((HINSTANCE)hInst,hrsrc);
...some time later
FreeResource((HGLOBAL)hGl);

does that help ?

I saw that yesterday in searching MSDN but unfortunately MSDN for Visual C++ 6.0 says...

"FreeResource
The FreeResource function is obsolete. It is provided to simplify porting of 16-bit Win32-based applications. It is not necessary for Win32-based applications to free resources loaded by using the LoadResource function. The resource obtained by LoadResource is automatically freed when the module is was loaded from is unloaded. However, to save memory and decrease the size of your process's working set, you should release the memory associated with accelerator tables, bitmaps, cursors, icons, and menus by calling the functions in the following table."
// End quote

I'm emdedding binary files and even though they are compressed, I just get that odd feeling leaving them in memory for the life of the application.

I'll probably concede that I'm looking for functionality that does not exist, unfortunately.

Thanks for the reply and help.

Wait. It just dawned on me that it was right under my nose all along.

From MSDN...
"The resource obtained by LoadResource is automatically freed when the module is was loaded from is unloaded."

I've been looking at it from the perspective of embedding the resource in my .exe when it looks like I should be using a "resource only" dll module. If I "LoadLibrary()" and "FreeLibrary()" for the resource module, the memory from "LockResource()" should be freed when I call "FreeLibrary()" according to the quote above. (Or at least when the reference count for the resource module goes to zero)

Do you think I'm barking up the wrong tree or is that probably the detail I've been ignorant of all along?
