CWnd::GetSafeHwnd
HWND GetSafeHwnd( ) const;
Return Value
Returns the window handle for a window. Returns NULL if the CWnd is not attached to a window or if it is used with a NULL CWnd pointer.
are you getting the hwnd before you start the thread?

Sorry, i got the solution(STUPID STUPID!!!), i wanted to get the HWND value BEFORE i did a DoModal() on my dialog,
no wonder it didn't work! Now i set the HWND value of the thread at the OnInitDialog with GetSafeHwnd() and it works fine! ;) 
thanks for your help!

Hi all,
I need a little help here . I have a simple program using Common control stuffs that require commctlr.h and comctl32.lib.
I created the project using Visual Studio .Net default template for Win32 Console application that includes stdafx.h precompiled header. Somehow this precompiled header makes the compiler not recognize the INITCOMMONCONTROLSEX structure defined in commctlr.h even though I've set up the project appropriately (correct path etc.)
I noticed in the commctlr.h the INITCOMMONCONTROLSEX is surrounded by conditional (_WIN32_IE >= 0x0300). I thought that my project re-defined _WIN32_IE to be less that 0x0300 somewhere, but after I did intensive search, it's nowhere to be found.
Anyway, does anybody know what's happening here? Could you help me please? 
NOTE: If I start the project from the scratch (i.e. without using the precompiled header), it compiles fine and smooth.
Thanks alot,
d-man

Hi,
I need to implement uint40, where the compiler I am using (in an embedded environment) only supports up to uint32. It would be interesting to have a look at C++ implementations (or even C) for int40 or int64. The only one I found was the Putty C implementation of int64.

Victor

__int64 is a built-in type in VC++.

This is how VC++ implement the __int64 using Assembly, remember that all processors register are 32 (except 64 bit CPU of course) and all operations are done on them at the processor level.
Anyway these are C++ statements with corresponding Assembly, it you may be able to implement using Assembly.

there are some function for multiplication and division, but I could not get their code.

Hi,
I'm overriding the WM_NCLBUTTONDOWN event for my dialog. I found out that I need to send the WM_SYSCOMMAND message so the buttons (min,max,close) still work. Everything is ok but when I want to resize, the cursor is moved at the center of the dialog so it's nearly impossible to resize the window.
What I am doing wrong???
Thanks!
LRESULT CBlankDlg::OnNcLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
if( GetAsyncKeyState( VK_LCONTROL ) || GetAsyncKeyState( VK_LCONTROL ) )
{
INT i=0;
}
LONG msg;
switch( wParam )
{
case 2:
msg = SC_MOVE;
break;
case 20:
msg = SC_CLOSE;
break;
case 9:
if( m_isMaximized )
{
m_isMaximized = FALSE;
msg = SC_RESTORE;
}
else
{
m_isMaximized = TRUE;
msg = SC_MAXIMIZE;
}
break;
case 8:
m_isMaximized = FALSE;
msg = SC_MINIMIZE;
break;
case 17:
msg = SC_SIZE;
break;
}
SendMessage( WM_SYSCOMMAND, msg, lparam );
return 0;
}

How do you remove the default icon that appears in the upper left hand corner of a child frame window on the title bar in an MDI style application?
LIFE IS COOl
|
|
|
|
|
It's an icon in your app. You can change it.
Also, when you create the window you can adjust the create struct to not include the app icon. CS_something.

|

Remove the WS_SYSMENU style from your window. Keep in mind that this will also disable Alt-Space as well.

I have a static library I have compiled with VS.Net -- the library compiles correctly. However, when I try to link against it I get link errors for multiply-defined symbols such as:
CWPDataManager error LNK2005: "public: class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> > & __thiscall std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >::operator+=(char)" (??Y?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAEAAV01@D@Z) already defined in MyDateD.lib(MyDate.obj)
My library makes use of std::string (as you can see above) and I've put the approriate #ifndef include guards in the library .h file. So, why do I get these link errors when I build my app and link against my libray? Anyone know where my problem is?
Thanks,
--Dean

Are there functions in the DLL that returns a pointer or reference to a string object? If so, one solution is to do return by value.
Kuphryn
|
|
|
|
|
Well, it's not a DLL - it's a static library. I have one function that takes a string by reference (consequently this is where the link errors arise from -- it's the only function that uses string). The function return is void and the string that is passed by reference is modified within the function.
The function (inside the library) looks like this:
void CMyClass::format(const char* fmt, string& dest)
{
...
(modify dest)
...
}
--Dean
|
|
|
|
|
Okay.
See if you can pass in a const string and return the modified string instead of void.
Kuphryn
|
|

That's usually caused by the build settings for the LIB using one form of CRT linking (static or DLL) and the executable using the other.

in my OnPaint, i am drawing to a memory DC, then blitting to the screen. if i do memDC.DrawFocusRect(...), then Blt, the rectangle turns out light blue (ie. wrong). but if i Blt then draw the focus rect onto the screen DC, it comes out black-and-white dashed (as it should).
memDC.DrawFocusRect(CRect(10,10,100,100));
dc.BitBlt(frameRect.left, frameRect.top, frameRect.Width(), frameRect.Height(), &memDC, 0,0, SRCCOPY);
memDC.SelectObject(ob);
dc.DrawFocusRect(CRect(10,10,100,100));

play around with SetTextColor and SetBkColor for that device, i'm not exactly sure which parameters you'll need but changing those affects the focus rect

Is the mem DC's setup exactly the same as the screen DC?
|
|
|
|
|
i think it is...
CPaintDC dc(this);
CDialog::OnPaint();
CDC memDC;
if (memDC.CreateCompatibleDC(&dc))
{
CBitmap bmp;
if (bmp.CreateCompatibleBitmap(&dc, frameRect.Width(), frameRect.Height()))
{
CBitmap *ob = memDC.SelectObject(&bmp);
if (ob)
{
... draw the stuff in here
-c

This suggestion may be silly, but worth the try: initialize the memDC before calling CDialog::OnPaint(). Something like:
CPaintDC dc(this);
CDC memDC;
BOOL bCreated = memDC.CreateCompatibleDC(&dc);
CDialog::OnPaint();
if(bCreated)
{
...
}
Good luck!
