Or you could do:
TCHAR currDir [MAX_PATH];
DWORD dwRet = ::GetCurrentDirectory (MAX_PATH - 1, currDir);
ASSERT (dwRet != 0);
CString strCurrDir = currDir; /ravi

You could just use strINIFilePath directly:
CString strINIFilePath;
GetCurrentDirectory(MAX_PATH, strINIFilePath.GetBuffer(MAX_PATH));
strINIFilePath.ReleaseBuffer();

hi,everyone.
I am learining how to use GDI+.
I do the following things in my programme:
1. Include gdiplus.h
2. Add the gdiplus.lib in Project->Settings->Link-> Object/library modules .
3. Add "using namespace Gdiplus" at the beginning of the source code.
4. Initialize GDI+ using GdiplusStartup.
but I got a lot of errors:
Compiling...

Error executing cl.exe.
TryGdipp.exe - 17 error(s), 3 warning(s)
So I includeed
typedef unsigned __int64 ULONG_PTR;
in stdafx.h and there left one error:
f:\microsoft visual studio\myprojects\trygdipp\stdafx.h(22) : error C2871: 'GdiPlus' : does not exist or is not a namespace
Error executing cl.exe.
Can someone tell me how to solve the problem?
Thank you!

but now there comes another error....

Whilst I can get all the processes running on my workstation and hence a handle to the process, and the .EXE name. How can I get the commandline arguments for that process ?
I'm trying to write an app so that I can identify the processes better, as we have several wscript.exe scripts run at login time, but some need to be killed by the user after login, any help would be gratefully received.

I have made deskband object. How to programmatically show and hide it?
If that was explorer bar, i'd use IWebBrowser2::ShowBrowserBar.
Thank you!

Just for learning purposes, I'm trying to implement the code Mark Petrik Sosa put in a message at 6:47 14 Apr '05 in a reply to 'Send Messages to Other Windows' (4:34 14 Apr '05).
<br />
HWND hNotepad = FindWindowEx(0, 0, "Notepad", 0);<br />
if(hNotepad)<br />
SendMessage(hNotepad, WM_SETTEXT, 0, (LPARAM) "Hah, I found you!");<br />
else<br />
MessageBox(0, "Couldn't find notepad.", "Darn", MB_OK);<br />
<br />
When I compile, I get:<br />
error C2440: 'initializing' : cannot convert from 'CWnd*' to 'HWND'<br />
error C2660: 'CWnd::SendMessageA': function does not take 4 arguments<br />
<br />
If I change to <br />
CWnd* hNotepad = ...<br />
and then<br />
SendMessage(hNotePad->m_hWnd, ...<br />
I still get the C2660 error.<br />
<br />
I also get<br />
'CWnd::MessageBoxA': function does not take 4 arguments<br />
I can see that SendMessage has 2 prototypes - one takes 3 arguments and looks like it's for the cases where you do not need to specify a handle.
Would appreciate any direction on how to fix the code and/or explanations to help me understand the mechanisms involved here.

::SendMessage(hNotepad, WM_SETTEXT, 0, (LPARAM) "Hah, I found you!");
and
::MessageBox(0, "Couldn't find notepad.", "Darn", MB_OK); or MessageBox("Couldn't find notepad.", "Darn", MB_OK);

Thanks.
It now compiles and executes properly.
If you have another minute though, I still get the error 'initializing': cannot convert from CWnd* to HWND unless I declare hNotepad as CWnd*. Then when I do that I have to use hNotepad->m_hWnd, which makes sense. Is there some include file I need such that I can declare hNotepad as HWND and then use it as you and Mark used it (i.e., without the ->m_hWnd)?

If you dereference your pointer ( *hNotepad ), then operator HWND should come to the rescue.

I haven't found the secret yet. If I still declare with CWnd
<br />
CWnd* hNotepad = FindWindowEx(...<br />
then I can use
<br />
::SendMessage(*hNotePad, ...<br />
But if I declare with
<br />
HWND hNotepad = FindWindowEx(...<br />
or
<br />
HWND *hNotepad = FindWindowEx(...<br />
I still get the error message
'initializing' cannot convert from CWnd to HWND
Is it maybe because the 2003 compiler is more strict than compilers in the past? I don't have much experience/history with Visual C++.

Has anyone ever tried (and managed) passing the IP number of the remote machine instead of the machine name in the remote filename url?
I can successfully create a BITS job when i specify the remote file using the machine name in the url, but somehow the job cannot be created when i specify the ip number of the same machine in the url instead of the name. Any ideas anyone?
(If it can help, the remote machine ip is dhcp-assigned, but i don't think this can create a conflict)

Hi,
How can I get the DWORD or Binary Value using RegQueryValueEx function?
Cheers,
Thanks.
|
|
|
|
|
<code>DWORD dKeyValue;
DWORD dType;
DWORD dSize=sizeof(DWORD);
RegQueryValueEx( hKey, "KeyName", NULL, &dType,
reinterpret_cast<LPBYTE>(&dKeyValue), &dSize)</code>

Hi guys
I'm working in an app that starts to be big and I have a little-big problem.
When I touch an .h file the VC++ 6.0 recompiles practically the complete app.
Why do you think this is due to?
There is some Setting to change?
Is due to includes?
Some clue?
Have you experimented this too? 
Thanks in forwarding
Doc

Visual C++ will recompile any file that it decides is dependent on that file. If you edit a commonly-used header, it will recompile most of the application.
To resolve this, first remove any unnecessary includes from source files - only include those headers actually required. If you're using a precompiled header file (a default VC project uses StdAfx.h as the header file for generating precompiled headers) you should only include in that header headers that are very stable.
In some cases you may have used #include in a header file where the actual definition is not required - i.e. the class declared in the header is only passed or stored as a pointer or as a reference. If this is the case you can remove the #include and only give a forward declaration, e.g.
#include "MyClass.h"
class MyOtherClass
{
public:
MyOtherClass( MyClass* pMyClass );
private:
MyClass* m_pMyClass;
};
class MyClass;
class MyOtherClass
{
public:
MyOtherClass( MyClass* pMyClass );
private:
MyClass* m_pMyClass;
};If this is still causing too much to be regenerated, you can use a trick called, variously, a compilation firewall, the Cheshire Cat technique, or the Pimpl Idiom[^]. Pimpl stands for Pointer-to-implementation.
Stability. What an interesting concept. -- Chris Maunder

Thanks guy
I'll take a look about this.
The point then is replace includes by class where possible?
