Have a look at FindFirstFile and friends.

This function searches a directory for a file whose name matches the specified file name. FindFirstFile examines subdirectory names as well as file names.

I don't know the name of the file.

Look deeper into the docs Smile | :)

The function supports wildcards, take advantage of them.

It says that cout is an undecalred identifier when i #include <iostream>

thanks

It is std::cout, although many samples omit the prefix for brevity.
You can stick to the simpler cout including

using namespace std;

right after the #includes, though this is not, for a variety of reasons, a good policy to follow in general.

Can I download it from some webstite ?
I need the 6.0 release (or later).

Please help! OMG | :OMG:

Several Intro to Visual C++ type books offer the Introductory Version on CD with the book. I did this, thinking it was the Standard Version.

Hi I want to create a dynamic link library in Visual C++ for use in Visual Basic.
From VB i pass a String to the dll, so far so good, but now i want to return another String to the VB-program. My problem is now the memory access error, that occurs in the running VB programm.
What types in the c++dll can i return to VB, that expect a String??

thanx for your replies

Catching OutputDebugStrings

23-Oct-02 2:23

A BSTR, I think. CComBSTR could be useful to do this.

I though about creating a Edit window in my app that when called
at runtime would catch all OutputDebugStrings that my program was
making.

After some nosing about on MSDN about catching OutPutDebugStrings i
wrote a thread function as below and called it from a menu option. The
idea was to eventually create a small window that would be updated with
any OutPutDebugStrings that were caught.

<br />
UINT catchDebugString(LPVOID param)<br />
{<br />
	TCHAR myChar[1024];<br />
	DWORD dwProcessId = GetCurrentProcessId();<br />
	HANDLE hHandle = OpenProcess( PROCESS_ALL_ACCESS, false, dwProcessId );<br />
<br />
	if ( DebugActiveProcess( dwProcessId ) == 0 )<br />
        return 0;<br />
<br />
	DEBUG_EVENT de;<br />
    <br />
	while ( WaitForDebugEvent( &de, INFINITE ) )<br />
	{   <br />
		if ( de.dwDebugEventCode == OUTPUT_DEBUG_STRING_EVENT )<br />
		{<br />
			OUTPUT_DEBUG_STRING_INFO deStr = de.u.DebugString; <br />
<br />
   			ReadProcessMemory(hHandle, deStr.lpDebugStringData, myChar, 1024, NULL);<br />
		}<br />
	                     <br />
		if ( EXIT_PROCESS_DEBUG_EVENT == de.dwDebugEventCode )<br />
			break;<br />
<br />
		ContinueDebugEvent( de.dwProcessId, de.dwThreadId, DBG_CONTINUE );<br />
	}     <br />
<br />
	return 1;<br />
}<br />

All was well until i found out i cant call DebugActiveProcess( dwProcessId )
with my own process id , there by making it so i cant catch my own OutputDebugStrings.

I just wondered if anyone out there had any ideas of how i could overcome this
problem or if there is another way to catch OutputDebugStrings??

cheers

Help on drawing a CButton in an ActiveX control

I'm trying to draw a button and an ip address area in my active x control.

I thought I could just use the ResourceView->Dialog to add the components visually, but evidently that only allows you to manipulate the property and about box areas for activex programs.

So... my question is how do I draw, say, a simple CButton in the ondraw area of my control?

something like:

void CAChatCtrl::ondraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{   
   CButton testButton = new Button();   
   CRect bBounds = new CRect( rcBounds->r - 30, rcBounds->b - 30, rcBounds->r, rcBounds->b );
   testButton::Create("DrawnButon",BS_DEFPUSHBUTTON,bBounds,?,??);
}

Thanks for any help
