How can I use vector.h in an MFC app?
class_a.cpp:
<br />
#include "stdafx.h"<br />
#include "class_b.h"<br />
class_b.h:
<br />
#include "vector"<br />
class_b.cpp:
<br />
#include "stdafx.h><br />
#include "class_b.h"<br />
There's no code yet.
Compiling class_b.cpp is no problem.
But compiling class_a results in a whole bunch of compiler errors (inside new.h, memory.h, ...). I think it has something to do with namespaces, but I'm not sure. I'm not declaring nor using namespaces of my own. Could also be an debug/release prob.
These are (part of) the errors:
<br />
vc98\include\new(35) : error C2061: syntax error : identifier 'THIS_FILE'<br />
vc98\include\new(35) : error C2091: function returns function<br />
vc98\include\new(35) : error C2809: 'operator new' has no formal parameters<br />
vc98\include\new(36) : error C2061: syntax error : identifier 'THIS_FILE'<br />
vc98\include\new(37) : error C2091: function returns function<br />
vc98\include\new(37) : error C2556: 'void *(__cdecl *__cdecl operator new(void))(unsigned int,const struct std::nothrow_t &)' : overloaded function differs only by return type from 'void *(__cdecl *__cdecl operator new(void))(unsigned int)'<br />
vc98\include\new(35) : see declaration of 'new'<br />
...
What do I have to do?

hi,
Add code below in in stdafx.h
include <vector>
using namespace std;
This will do.
Cheers

You might want to make sure the #include >vector< appears before the block that reads
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
in all your files. One way to do this would be to put the #include inside stdafx.h instead.

I've already tried to put the include everywhere, above, under, in another file, ... It didn't work.
I've tried it once again, and guess what...
tnx m8.

Is the mixing of '"' and '>' a typo?
There is nothing more in your files than what you wrote? Then you probably need to add
class_a.cpp:<br />
#include "class_a.h"
Does it help?

Hi All
How can I design the form in vc++ that should appear like a form which pops up when we click at office assistance help in MS Word.
Thanks
|

Just a dialog box but to have some background invisible.
There are some articles in codeproject which explain this.

These assistant are called MSAgent
And there is complete SDK Available for programming these agents,
one can download this SDK from microsoft Site.
There are many third party characters available as well.
Microsoft also provide MsAgent editor , using which one can create its own characters.

I would like to make my program to fit into paper
when printing out. I know we should deal with that
with this function but I am not sure about parameter
Does anyone know what to put?
BITMAPINFOHEADER *pBMI = (BITMAPINFOHEADER*)(LPVOID)lock;
int nColors = 0;
if( pBMI->biBitCount <= 8 )
nColors = ( 1<< pBMI->biBitCount );
if( b_PrintFit )
{
::StretchDIBits( pDC->GetSafeHdc( ),
pInfo->m_rectDraw.left,
pInfo->m_rectDraw.top,
pBMI->biWidth,
pBMI->biHeight,
0,
0,
pBMI->biWidth,
pBMI->biHeight,
(LPBYTE)pBMI + (pBMI->biSize + nColors * sizeof(RGBQUAD)),
(BITMAPINFO*)pBMI,
DIB_RGB_COLORS,
SRCCOPY);
Thanks

10th parameter of StretchDIBits should be a pointer to a buffer containing RGB data of bitmap you want to print.
For eg.
CBitmap bmp;
bmp.LoadBitmap(IDB_SOMEBITMAP);
BITMAP bm;
bmp.GetBitmap(&bm);
bm.bmBits is the pointer you need.
Other parameters may be right or wrong cause I dont know what they mean in your program.
By the way, for printing a bitmap you should to create a printer DC and to calculate destination rectangle with paper resolution.
For more info see MSDN!

recently, i found there is a useful feature in HyperSnap-DX 5, that is capturing the whole scrolled window content into a big bitmap, and I think it is very interesting and try to impliment it in VC,but i failed.I have tried to use ScrollWindowEx, WM_VSCROLL and others, does anynone has any idea on the problem?

Hi all,
I've created a MFC extention dll project. in the stdafx.h file i've wrote:
#undef _GUI_LIB_EXPORT_
#ifdef _EXPORT_GUI_LIB_
#define _GUI_LIB_EXPORT_ __declspec(dllexport)
#else
#define _GUI_LIB_EXPORT_ __declspec(dllimport)
#endif
i have 2 exported classes, 1 is a dialog, the other one is a button:
1) class _GUI_LIB_EXPORT_ CMyDlg : public CDialog
2) class _GUI_LIB_EXPORT_ CMyBtn : public CButton
i use an MFC exe project to test my dll.
in the stdafx.h i also write :
#undef _GUI_LIB_EXPORT_
#ifdef _EXPORT_GUI_LIB_
#define _GUI_LIB_EXPORT_ __declspec(dllexport)
#else
#define _GUI_LIB_EXPORT_ __declspec(dllimport)
#endif
when i compile the exe project (that uses the exported dialog and button classes), it seams to recognize the dialog exported class (CMyDlg) but for the CMyBtn class i get the warning C4273 - inconsistent dll linkage. dllexport assumed.
can any1 help???
i am desparate here..
thanks in advanced,
Yaron

Isn't the class to be dllexport is what is you want? So, it is correct then. Unless you are importing functions from DLLs.
Why use the macro? Just put in like this
class __declspec(dllexport) CMyDlg : public CDialog<br />
{<br />
...
why making yourself confuse?
hope this helps

remove the stuff you wrote in the stdafx.h. In your dll project place "_EXPORT_GUI_LIB_" in the preprocessor definitions (project settings). This way the classes will be exported when you have defined "_EXPORT_GUI_LIB_" and imported if not defined (as in your client project). Hope this explains it a bit.

Hi,
I have an MFC ActiveX application and on a certain scenario (timing dependent I think) it crashes
with either an "Access Violation" or "Invalid Instruction", and the call stack simply shows:
"GUI! _except_list". I don't get any source file where the crash occured, just some disassembly which doesn't look like valid code (About 100 lines of the same code line in assembly - mov
dword... repreated 100 times or more).
I used BoundsChecker with maxium error checking, but it didn't catch anything.
Any ideas how to catch this?
Thanks.

Check your *.pdb files. This is where your debugger gets the symbols.(source codes) when debugging.
Hope this helps

Hi,
I found the "except_list" string in my PDB, but it doesn't really tell me anything.
Here's a part of the PDB with the except_list in it.
Every line has an address on the left side, but I didn't add those here.
AfxGetApp@@YGPAVCWinApp@@XZ \q??_7CGUIDlg@@6B@* _numega_finalcheck_Y_110455" 8a ??0CStatic@@QAE@XZ* ü] ??0CDialog@@QAE@IPAVCWnd@@@Z" g ___CxxFrameHandler

What can I do with this info?
Thanks.

You need to have your *.pdb files to be with your *.ocx.
And one more point in case you have forgotten. You need to have your project build in debug mode.
hope this helps
