Are you doing that for fun, or have you tried to find the decoder and it is not available?
Part fun, part serious. We have a client who's been using this image format for almost 20 years. The main program is in GWBASIC and they have this external program [written with assembler]. Partial sources available. Long assembler listings 
I understand that the first 32 bytes is some kinda header. The rest of it has a lot of 0xFFs in them. I am assuming the 0xFFs are the black spaces and am making guessed at what the other bytes mean.
One problem is I don't know the width of the image in pixels!!!

How do I draw a pixel into a CView?
Don't, it will be dog slow. Create a DIB section instead and get direct access to the bits, then blit that bitmap to the view. It will be both much faster and easier to handle.

Yeah it sure was slow
So slow it looked like some kinda animation where I could see it drawing it on screen

Hi,
I have pure Win32 based project with own message loop, something like:
CreateWindow();
for (;; )
{
EngineMain();
if(!PumpMessage()) break;
}
DestroyWindow();
When there is nothing todo (e.g. dialog is miminized) I would like to tell Windows that I'm idle. Currently the CPU consumption is allways 100%, because the message loop is running like crazy, hehe. Well, I'd like to avoid that.
thx, Moak

You code never blocks, like GetMessage() normally does. You need some mechanism to make your thread block (and thus receive no CPU time) when the queue is empty, then unblock when a message arrives in the queue.

thx, i did without PeekMessage and it blocks + CPU consumption is low!

I am just curious, how did you end up doing it?

I'll block with WaitMessage() when there is no window visible. Member variable m_data.bVisible is set in my WindowProc callback handler (have a look on WM_SIZE).
BOOL CBlueSharkEngineWindow::PumpMessage()
{
assert(m_data.bCreated);
assert(m_pInterface);
MSG msg;
while (::PeekMessage (&msg,NULL,0,0,PM_NOREMOVE))
{
if (!::GetMessage (&msg, NULL, 0, 0))
{
m_pInterface->pConsole->Logfile(SHARKENGINE_LOG_DEBUG3, "Quit message received");
return FALSE;
}
::TranslateMessage (&msg);
::DispatchMessage (&msg);
}
if(!m_data.bVisible) WaitMessage();
return TRUE;
}

I think you should create a worker thread that does whatever your EngineMain funtion is doing. Thus, you can still handle all other Windows messages

I used SetWindowsHookEx(WH_MOUSE,....) to get mouse message.
After get mouse message(like WM_RBUTTONUP...)I need to redirect it.
For example, when user clicks right button, I want call 'Run...' dialog.
I know that I need to disable popup menu and then to do what I want it to do.
Below is my code:
HHOOK glhHook = NULL;
HINSTANCE glhInstance = NULL;
glhook = SetWindowsHookEx(WH_MOUSE, MouseProc, glhInstance, 0);
.
.
.
LRESULT WINAPI CALLBACK MouseProc(int nCode, WPARAM wp, LPARAM lp)
{
if(wp == WM_RBUTTONUP)
{
// do something....
((MOUSEHOOKSTRUCT*)lp->hwnd = NULL;
((MOUSEHOOKSTRUCT*)lp->wHitTestCode = NULL;
((MOUSEHOOKSTRUCT*)lp->dwExtraInfo = NULL;
return false;
}
}
but it still show the popup menu and ignore the action I want to do
why???
Is anybody can give me some suggestion?

First, make sure that your code is in a DLL, message hook procs need to be placed in a DLL.
Second, is your code not being called at all, or it is being called, but what you want to happen is not happening?
When you do get your code to happen, you will not want to send the message on to the other hooks in the chain. If you want to prevent whatever app that should receive the mouse message from displaying the context menu, the only way to do this is to make sure that they do not receive the message.

hi, does any body know what this macro does??
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
}
#endif
i found it in a headfile and i have no clue

It will turn off name mangling for your program symbols. Which means that programs that are written in a different language besides C++ or even different C++ compilers will be able to use your code. THis also means that you will not be able to take advantage of certain C++ features like function overloading.

Im trying to create a background for my application using BitBlt()
Works fine. The image includes butten (I drew some buttons on the image)
And I want them to be clickable.
How can I add a clickable zone? e.g a simple butten, but will not be visable but clickable.
thanks

Instead of a button use a static control. Remember to set the SS_NOTIFY style to get mouse clicks.

You could monitor the LBUTTONDOWN and LBUTTONUP combinations to determine if the user clicked the mouse. You would then determine the rectangle where the buttons are on your image, and you could check to see which button should be clicked (if a buttons should be clicked) by testing the point that was clicked in the function PtInRect.

fatal error RC1004: unexpected end of file found
File of interest is a header file as follows:
// define for the application icon
#define ICON_T3DX 100
// define for the application cursor
#define CURSOR_CROSSHAIR 200
// define for the application music
#define SOUND_ID_MUSIC 1
// defines for the top level menu OPTIONS

#define MENU_HELP_ABOUT 2000
#define MENU_HELP_INSTRUCTIONS 2001
Tried including stdafx.h but it didn't fix it.
Help!

How does your CPP file look like. The oroblem may be because of header files included before or after. How do you know that this is the file that causes the error.

Suppose I have just installed VS .NET, and there were no earlier version of VC++ on my machine, would I be able to run pre-.NET applications on my machine? IOW, would I be able to run unmanaged C++ applications on my computer?
Thanks.

Of course! Do you think Microsoft would kill of such a huge amount of applications just because you installed VS.NET? Pretty much everything in the world is written in unmanaged code!

to get the device context of a dialog box we write the statement
CClientDC dc(this);
what if i have to get the device context of a picture box control.
God helps those who help others.

Just replace this with a (CWnd derived) control reference:
CClientDC dc(&m_myPictureBox);
- or -
CClientDC dc(GetDlgItem(IDC_MY_PICTURE_BOX));
