Hi all,

I posted this a couple days ago but didn't get any response. Thought i would try to post it again and see if someone could help.

Wanted to know if it is possible to both pad a hex numbers with leading 0's and also format the width of the message.

I have a string and i just concat a hex number to it. I just want to space out the numbers so that they will line up with the next string added, so that it has the look of a table.

Right now i am padding the hex number like this:

int myString = 10005;
int myString2 = 20003;
testStr.Format("%03X" , myString);
Str += testStr;
testStr.Format("%03X" , myString2);
Str += testStr;
Listbox.AddString(Str);

I know if i take away the 0, then it will set the width, but i need to do both. CAN THIS BE DONE?

thanks in advance.

Sure: You know the width of your column, the length of your hex number, and the difference of both is the number of leading '0' you have to prepend.

You could do it in two stages, format the hex value, then take that as further input to another Format call, using %8.8s (pad on right) or %-8.8s (pad on left) as the format string second time around

eg
testStr1.Format("%03X",myString);
testStr2.Format("%03X",myString2);
Str.Format("%10.10s%10.10s",testStr1,testStr2);

and, (haven't used Format or printf for a while...) you can specify the field width as an argument itself, like this;

testStr.Format("%0*X", n, myString)
where n is the number of digits you want.

Vector inside MFC app?

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.

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...

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?

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.

StretchDIBits fit into paper

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!

warning C4273 - inconsistent dll linkage. dllexport assumed.

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

warning C4273 - inconsistent dll linkage. dllexport assumed.

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
