First of all, I'm a beginner.  Second, I make a program that should launch an EXE. Not just EXEs, but different games. Some of them launch, but most of them like Call of Duty, Vice City and others don't.Some games say, they cannon find some settings files, some just critical errors, CoD even shows a message that it has searched files in a wrong folder (should be "D:\games\Call of Duty - United Offensive\uo" but he searches in "D:\games\Call of Duty - United Offensive\uo/uo". I've tried all found functions except for CreateProcess. What can cause the problem?

Well, AFAIK there are two main elements to watch when launching external programs:
. Current directory
. Parameters
If your games EXE relies on the current directory (which may affect the search path) or any given parameters, then that could be a reason.
Have a look at the properties of the launch shortcut to see what it is passing to the OS to launch the programs.

Well, now I know the reason: directory parameter of ShellExecute was NULL. Now all works (except for 1 game shows black screen only on loading). Thanks for reply.

That isn't using ostream ...
If you want to use ostream (specifically, ofstream):
ofstream fout("file.txt", ios::out | ios::app);
fout << "Hello, world!" << endl;
That will open a file named "file.txt" for output and append "Hello, world!" to the end of the file.

Hey guys,
The additional include directory in the project Im looking @ is listed as below
$(RTI_HOME)/$(RTI_BUILD_TYPE)/include
I am working with Windows OS but I'm still confused why it still works with $ sign
in front of the environment variables.
I thought ($) sign in front of environment variables is suppose to mean you are working
with a Linux/Unix environment and (%) sign in front of environment variables is
suppose to mean you are working with the Windows OS.
Someone help me out here.....
Thanks in advance

it's not a Windows or Unix thing, it's a Visual Studio thing.

($) is a Visual Studio thing?
then when do we use (%) and ($) while referring to different OS directories

when you said "project", i assumed you were talking about VS. and VS uses $(name) for its configuration macros.

I have an MFC app and I'd like to get notified whenever a any of several possible child windows recv focus. I thought I could just override the main window's PreTranslateMessage() function and simply check the pMsg->message value and if it's a WM_SETFOCUS and the pMsg->hWnd is one of the windows I care about then react accordingly. However I never get ANY WM_SETFOCUS messages!
Am I misunderstanding how PreTranslateMessage is supposed to be used or is there an alternate approach? I'd prefer not to have to subclass each of the controls, but I will if I have to.

AFAIK the WM_* messages are sent to the pMsg->hWnd window. If that window does not handle the message then it is sent to the parent of that window and on up the parent chain until one of the windows actually handles the message (returns TRUE), or the there are no more parent windows. So the only way the main window will get the WM_SETFOCUS message is if none of the child windows handle it, or they return false if they do.
See CWnd::WalkPretranslateTree() and AfxInternalPreTranslateMessage() in the MFC sources for more details (Set a breakpoint in your PreTranslateMessage() function and use the call stack)

the problem is not from the way u try to catch the message, but from the message u want to catch, WM_SETFOCUS cound't be caught, I tried to catch it in the simplest window's program. catch this message before TranslateMessage calls, but still, couldn't get it. somebody knows why?
life is like a box of chocolate,you never know what you r going to get.

Jim, did you get a solution for this without rewriting all your child controls?
You may find that setting up a WH_CALLWNDPROC hook is the easiest way to be notified when a window in your app recieves the WM_SETFOCUS message.

No, in the end I just added the OnSetFocus() methods to the various controls.  Wasn't that big of a deal, just annoying. But then that pretty much sums up MFC development, for me at least

Whenever the thump of the HScroll goes to the end of the scroll bar in the CListCtrl, I will add the 20 records in the listctrl. It will be attain by inserting the record at the HScroll method, by calculating the thump value. Whether the thump is getting to the end, then only I will add the records. But I met the problem which is When I track the thump to the end of the HScroll, the mouse holding the Thump. At the time I need to release the mouse from the holding of thump. I have tried by posting the message of WM_LBUTTONUP by the
SendMessage(WM_LBUTTONUP);
function. Please help me..

If you need to release the mouse capture and stop scrolling, I think you can try this sequence:
SetCapture();
ReleaseCapture();
I hope it helps.

Hi Everyone.... i am trying to get this piece of code working over a WAN connection, when i use it on a LAN it works ok.. but when i use it on a wan i can create the connection etc, create and remove directories etc, but as soon as i try to use the openfile function it crashes, does anyone have any ideas why ??
oh, i have tried to use passive rather than Active mode, when i do this i cant use the FtpFindFile function ??
just wondered if anyone had any pointers....
this is the snippet of code..
<br />
CInternetSession oISession(AfxGetAppName());<br />
CFtpConnection* poFtpConnection;<br />
<br />
poFtpConnection = oISession.GetFtpConnection(csSite,"xxx","xxxxx",2001,FALSE);<br />
<br />
poFtpConnection->GetCurrentDirectory(csCurDir);<br />
<br />
poFtpConnection->CreateDirectory(csDir);<br />
poFtpConnection->SetCurrentDirectory(csCurDir + csDir);<br />
<br />
CInternetFile* pInternetFile = poFtpConnection->OpenFile(csFile, GENERIC_WRITE,FTP_TRANSFER_TYPE_BINARY);<br />
<br />
The bold part is where it is falling down...
Any help would be appreciated..
Thanks
Lee

Have you stepped into the OpenFile() method to narrow the problem down further?

yes, it is falling over at the FtpOpenFile method..., the m_hConnection is a valid handle but the hFile that gets returned is NULL ??

When that function fails, what does GetLastError() return?

i have everything in a try catch block, so when it fails its caught and at that point the getlasterror function returns 0 ???? its just baffling me, because it works ok on a lan...

So what exception is thrown?
