Please go through the function prototype again. There may be some mismatch.

If that is OK then try to link the libray as following preprocesser directive.
#pragma comment(lib,"full path of library")
put above line in .cpp file below the header includes

Hi everyone,
Maybe my question is funny but I want to know what is it?

CMap<UINT,UINT,UINT,UINT> Map;Map m_Map;or CList <int> m;
or typedef CMap<UINT,UINT,UINT,UINT> m_Map;I know that typedef declare a new kind of an exist kind

This means that, these classes requires templete arguments.

Sorry I ask again I have another question can you explain for me For example what is it CMap<int,int,int> Map; Map m;
thank you prasad_som

prasad_som13-Dec-06 19:34

Possibly you are asking, what is

typedef CMap<UINT,UINT,UINT,UINT> Map;
 Map m.

Because, what you have asked is not possible.

Its used just to increase redability.

When we must use of this case of course I know its depends to our program
I cant understand what is it typedef CMap<UINT,UINT,UINT,UINT> Map; Map m.

typedef

typedef is keyword for declaring synonym for type declarations.
i.e.
typedef char TCHAR;
Now, TCHAR
can be used instead of char.

typedef CMap<UINT,UINT,UINT,UINT> Map;

This statement indicates Map is synonym of CMap<UINT,UINT,UINT,UINT> .So statement
Map m ; is actually CMap<UINT,UINT,UINT,UINT> m;

These are wrapper classes for STL::map and STL:list respectively.
Go through the following article for more info about maps.

You can see , MFC has its own implementation.

I have a transparent image (BMP) that I want to be able to place text on.

I have used SekBkMode to set TRANSPARENT, and also set the brush to bsClear.

This works great for old-style fonts, however True Type fonts seem to have some kind of anti-aliasing built it. When these fonts are drawn onto the canvas (at larger font sizes), the curves are edged in a colour halfway between the font colour and the transparent colour which makes them a little unsightly.

I can't just copy whats behind the text and use that as a background, as the layer beneath is liable to change at any time.

Is there any way to disable this effect?
Can I use fonts like Arial or Copperplate-Gothic-Light in font sizes above 16 without getting strange colours?

Calling an function in a DLL

I'm sorry to disturb all of you, I feel like I'm missing something here.

I'm trying to use call a function in a DLL I have written and have so far done this:

DLL Side

int __stdcall Topo(LPSTR Param)<br />
{<br />
<code><br />
}

Calling Function side

typedef int (__stdcall * FuncPtr)(LPTSTR);<br />
<br />
int APIENTRY WinMain(HINSTANCE hInstance,<br />
                     HINSTANCE hPrevInstance,<br />
                     LPSTR     lpCmdLine,<br />
                     int       nCmdShow)<br />
{<br />
	HMODULE TopoPtr;<br />
	FuncPtr TopoFunc;<br />
	CHAR Output[50]={0};<br />
<br />
	if (TopoPtr = (HMODULE) LoadLibrary ("<location of DLL>") )<br />
	{		<br />
		TopoFunc  = (FuncPtr)GetProcAddress(TopoPtr, "Topo");<br />
		if ( TopoFunc && TopoPtr )<br />
		{<br />
			TopoFunc(<Params>);<br />
		}<br />
		FreeLibrary ( TopoPtr );<br />
	}<br />
<br />
	return 0;<br />
}

Export.def

LIBRARY CheckTopo<br />
EXPORTS<br />
     Topo	@1

The error is this: When I call TopoFunc, I get a stack overflow. Tracing it by stepping through, I find that the stack overflow occurs BEFORE I enter the code in the DLL Side. Is there something wrong with my calling of the function? Or is it nothing to do with that and that I should be looking at something else?

Did you miss to pass string here ?

No, I just removed all the irrelevant code. I did remember to pass the string. It is a LPTSTR.

And as to the other poster's statement, been there, done that. It is calling into the debug dll correctly, but the stack overflows when the program steps through from the calling EXE to the debug DLL in VC++

Setting a menu to OWNERDRAW

Hi All
I've got a menu to attach to my class derived from CFrameWindow.
I would like to set my menu to OWNERDRAW so that I can draw it and customize the layout.

In the constructor of my window class I put the following but GetMenuItemInfo doesn't work.
It never enters the if block so that I can set the MFT_OWNEDRAW style.
Retrieving the error code I've got 87 ERROR_INVALID_PARAMETER

Can you help me with that issue?
Regards

	SetMenu( &menu );	 <br />
	<br />
	<br />
	MENUITEMINFO itmInfo;<br />
	//Here it doesn't work. It never enters in<br />
        //the block<br />
	if(menu.GetMenuItemInfo( 1, &itmInfo ))<br />
	{<br />
		itmInfo.fType |= MFT_OWNERDRAW;<br />
		menu.SetMenuItemInfo( 0, &itmInfo );<br />

<br />
	menu.Detach();<br />

What is the "1" you are passing here? Is it an ID or a position? If it's a position then you
need to call like this:

if(menu.GetMenuItemInfo( 1, &itmInfo. TRUE ))
...
