It does not satisfy the "but without using predefined functions" requirement.

8-May-06 4:50

i have 2 types of buttons in my app, ones i create dynamically using Create Method and by this the OnChildNotify with WM_CTLCOLORBTN working 100% ok. the other type is resource buttons, where i place them in my resource editor on my dialog, and then in my code i use
void CDlg::DoDataExchange(CDataExchange* pDX)
to add a member to my button with the type of MyButton....but in this situation, i don't see the font change??? i've i place a break point (in debug mode) i do step in the if (CTLCOLORBTN == message) and i see the selectobject with my phone, but the result is not font changing but the font i see in the resources...

any ideas?

thanks

That was a mistake on my part. The CFont object should be a member of the dialog, and created in the constructor. In OnInitDialog(), call SetFont() for each of the buttons.

Try:

CMyButton::CMyButton()
{
    LOGFONT lf = {0};

    _tcscpy(lf.lfFaceName, _T("MS Sans Serif"));
    lf.lfHeight = 28;
    lf.lfWeight = FW_BOLD;

    m_font.CreateFontIndirect(&lf);
}
 
void CMyButton::PreSubclassWindow() 
{
    SetFont(&m_font);	
    CButton::PreSubclassWindow();
}

This requires a callback.
A quick search in the forum showed e.g. this article[^] as an answer to this all-time-favorite question.

"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation."

Hallo

,

I have the following problem: in a simple windows application "DynamicLoad.exe" a dll "DefExported.dll" is loaded. If I quit
the dll in InitInstance() with return FALSE instead of return TRUE,
I get memory leaks in the debugger at the end. Is it possible to change this?

Detected memory leaks!
Dumping objects ->
{96} client block at 0x0035A150, subtype c0, 64 bytes long.
a CDynLinkLibrary object at $0035A150, 64 bytes long
Object dump complete.
The program '[444] DynamicLoad.exe: Native' has exited with code 2 (0x2).

(Remark: FreeLibrary( hClcltr ) does not change anything, because return False results in 0 for HINSTANCE hClcltr=LoadLibrary("DefExported.dll").)

The problem is independent of the Microsoft Visual Studio Version (e.g. 6,7,8). The code to try out this, you can look at the page of "DLLs
are Simple! Part 3 By Mahmood Komeily" on this forum.

Just add in DefExported.cpp:

BOOL CDefExportedApp::InitInstance()
{
CWinApp::InitInstance();
return FALSE;
//return TRUE;
}

And in DefExported.h:

class CDefExportedApp : public CWinApp
{
public:
int Multiply(int ParOne,int ParTwo);
CDefExportedApp();

virtual BOOL InitInstance();

...
}

Thank yor for the fast answer. Smile | :)

I myself haven't forgotten to delete again new allocated memory.
Some memory allocations in the Microsoft code causes the leaks.

Maybe there exist work arounds: it's not necessary to quit the dll in
InitInstance(), it could be elsewhere. But in the dll it should be
decided that a loadlibrary-call returns with zero.
I thougth that this could be done best in InitInstance.

if you can package them in a DLL with C-style interfaces, sure.
