Why not show the actual class definitions? Your paraphrased version makes no sense.

Why dont you derive one class from another so you can use the function y from class A for example?
Have you declared pointers inside each class?

Hi..
are you including header files in both classes, i mean..
in A.h

#include "B.h"

and in B.h
#include "A.h"

if u give so definately u will get errors,
so include only in the first written class .
and in secondly written class just define the first class

class A;

try this hope it works..

Here is how I am doing it.

In the header...

COLORREF m_lLogClr[4];

//In the constructor..

m_lLogClr[0] = RGB(0, 0, 0);<br />
m_lLogClr[1] = RGB(142, 35, 35);<br />
m_lLogClr[2] = RGB(218,165,32);<br />
m_lLogClr[3] = RGB(35,35,142);<br />

Finally...

<br />
<br />
VOID CLogDlg::PostLog(TCHAR *pBytes, int iClr, int iSize)<br />
{<br />
	if(NULL != pBytes)<br />
	{<br />
		m_RichLogCtrl.HideSelection(TRUE, TRUE);<br />
		int iLen= m_RichLogCtrl.GetWindowTextLength();<br />
		m_RichLogCtrl.SetSel(iLen, iLen);<br />
		<br />
		CHARFORMAT cf = {0};<br />
		cf.dwEffects |= CFE_BOLD;<br />
		cf.dwEffects &= ~CFE_AUTOCOLOR;<br />
		cf.cbSize = sizeof(CHARFORMAT);<br />
		cf.dwMask = CFM_COLOR | CFM_FACE | CFM_SIZE | CFM_BOLD | CFM_CHARSET;<br />
		cf.crTextColor = m_lLogClr[iClr];<br />
<br />
		_tcscpy(cf.szFaceName, _T("MS Sans Serif"));<br />
		cf.bPitchAndFamily = FF_SWISS;<br />
		cf.yHeight = (iSize * 1440) / 72;<br />
<br />
		m_RichLogCtrl.SetSelectionCharFormat(cf);<br />
		m_RichLogCtrl.ReplaceSel(pBytes);<br />
		m_RichLogCtrl.SetSel(iLen, iLen);<br />
		m_RichLogCtrl.HideSelection(FALSE, TRUE);<br />
	}<br />

Hi,
I have a dialog based application which was initially in C:\ drive. After running the project in C:\ drive for a couple of times, I made a copy of it in the D:\ drive and when I run open the project file in the D:\ drive (clicking on the .sln file) and if I put a break point in say the OnInitDialog() of a dialog class, when I run the project, this break point
automatically goes to the same function but to the project in the C:\ drive.

Also when I try to go to the declaration of any function by pressing F12 at the function definition, an resolve ambiguity dialog is shown and the function declarations of the project in C:\ and D:\ drive are listed. In the above mentioned scenario, files names of the project in the C:\ drive are
represented in lower case (tab name in the workspace)

How do i get over this issue?
I am using VS 2003 on XP.

Make sure that for every include in your source code, you supply relative paths and not absolute paths. Check that also for all the include directories if necessary in the project options.

Hi Cédric Moonen,

After reading your reply, I created a dialog based application using the Wizard(without adding any code) and the similar behaviour as described in my earlier post is observed.
Is there any setting in VS that I need to check for??

What do you mean ? So, you created a completely new dialog Based application on the D drive. When you put a breakpoint in one of your function, it points to a source file on the C drive ? That's impossible because you don't have a similar solution on your C drive Unsure | :~

Could you explain clearly your problem ?

I create a project in the C:\ drive, run it once, then close the project.
Now make an extra copy the same project in the D:\ drive, then run this project in the D:\ drive. If I search for a string say OnInitDialog(), then in
my search result, I find that both the projects that in the C:\ and the D:\ are shown.

Delete File function for wildcards

Hi all,

I'm looking for a function that can delete files by means of a wild card.

If so, can anyone please provide some more information

Many Thanks in advance

I do not think that there is a standard Win32 API function do to that. You would need to enumerate items using the wildcard and then delete matching items one by one.

Peace!

Hi David, I have tried the following:

SHFILEOPSTRUCT wildcards;
wildcards.wFunc = FO_DELETE;
wildcards.hwnd=NULL;
wildcards.pFrom=(LPCTSTR)lpUpDownFiles[first].szUpFName;
wildcards.fFlags=FOF_FILESONLY;
SHFileOperation(wildcards);

But get the following error:
Error 7 error C2664: 'SHFileOperationA' : cannot convert parameter 1 from 'SHFILEOPSTRUCT' to 'LPSHFILEOPSTRUCTA'

Can you please help?

Many Thanks

The compiler is telling you the problem. SHFileOperation() is expectnng a pointer (to a SHFILEOPSTRUCT).

No memory has been assigned to lpFileOp. Why aren't you using:

SHFILEOPSTRUCT lpFileOp = {0};
lpFileOp.wFunc  = FO_DELETE;
lpFileOp.pFrom  = (LPCTSTR)lpUpDownFiles[first].szUpFName;
lpFileOp.fFlags = FOF_FILESONLY;
SHFileOperation(&lpFileOp);

Hi David ... What would I do in the following instance:
