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 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 #include s, though this is not, for a variety of reasons, a good policy to follow in general.

Hi all!

Please help!

Thank you!
I've found the same Introductory version on another book too:

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

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

Maybe Ivo Ivanov's API hooking revealed[^] can be of help here.

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

Hey there guys... Just found out that if you want to get the last error of api calls then just type:
@err,hr
into the watch window... A very useful tip i thought and saves you programaticaly calling the the GetLastError api function!

Hi,
I've got an app (running under Win2k) with a flexgrid control in. It works fine under an Administrator, but as a normal user we have the following:
PROBLEM - Running on machines that haven't previously had msflxgrd.ocx installed results in an "Unsupported operation" message box when we try loading the app.
We are using Installer 1.1, and have tried using the flexgrid merge module, as well as distributing msflxgrd.ocx by hand.
We have definitely tried 'regsvr32 msflxgrd.ocx' too!!!!!
I've used OLEView to look at the ocx registration details. Under and administrator, it can view all the details and expand the interface leaves fine. Under a normal user it can't get any details about the ocx. It just gives the error:
"CoGetClassObject failed.
Class not registered
REGDB_E_CLASSNOTREG ($80040154)"
On machines that already have msflxgrd.ocx, it seems to work fine.
Anyone have any ideas?
TIA,
Paul.

could it be that the ocx isn't getting installed properly? (i.e. the administor can read the file, but normal users can't)
