Dear Sir,
I have a question about how to kill a process:
We know, when a child process is created in the parent process, the child
process can be killed with the TerminateProcess(hHandleProcess, 1),But if
others child processes are created by the child process, how can I
kill them all.
For Example (from Tornado IDE):
When we use GNU tools to compile and link the source files, we usually use
the make.exe to interpret the makefile document, so the make.exe can be a
child process of a application(may be an IDE). But we know make.exe
will create may sub-processes(gcc.exe, ld.exe, make.exe, ect.), so how can I
kill the child process(make.exe) and all it's sub-processes in the application
(IDE).
I hope your help!!

You could use job objects, but they are available only on Windows 2000. The other option is to enumerate all processes in the system, retrieve parent-child information and kill apropriate ones. Note that there's no universal method for this - you'll have to use different APIs on Win9x and NT.

I'm using a CListCtrl in report mode and I want to use it with some multiline text (i.e. it has carriage lines in it). The problem is that the edit control the list view uses are single line elements and do not understand carriage returns or line feeds so i get a bunch of wonderful bars in the text. Anyone have an good solutions to the problem?
Okay I got the owner draw thing to work and I know have carriage returns. The problem is I can't see the text as the row height does not change. Anyone have any ideas on how to change the row height?

You'll have to use owner-draw. Search for LVS_OWNERDRAWFIXED in VC++ help, there's also sample in KB article Q131788.

I have the owner draw part working, but I don't see how to get it to recognize carriage returns and line feeds. Any ideas?

i'm taking a corispndence course and i'm on my second excersize. useing appwizard, i need to make a grid useing the fgrid control, np but i need to code a command button to clear all fields in the grid. is there some kind of short method for clearing them without havin to code each field? like a clear all fields kinda code?

There is no such thing as fgrid according to MSDN. There are several grid controls and you're obviously not a confident typist, so I presume you've made a typo.
If it's one of the grids provided as COM object then when you #imported it you would have got a class that calls the objects methods and you would be able to browse that for all the available methods.
If you can tell us which grid you're using, someone here may be able to help you.

Is there a good place I can park a global variable so that every class has easy access to it?
Thanks

stdafx, if you must resort to a global - they are Satanic and should be avoided.
I put stuff in my CWinApp derived class or CMainFrm, because I can get a pointer to it from anywhere.

Hi, do you guys remember that sheep program that's a screen mate? Basically it's a transparent image on the desktop that can move around. I was wondering if VC++ is the language I would have to use to make something similar to this. I want a transparent gif on my desktop without a window frame. Please help.
here's a link where you can download it.

Use CWindowDC dc(NULL) to get a device context of the screen. Then you can copy off the old image, draw your new one on, etc. I dunno if there is a better way to do animation than this, as I've never tried.

Hey!
In Win2k, if I call SetCurrentDirectory() with a specific directory,
it appears to work until I use a CFileDialog.
When the file open dialog appears, it usually opens in "My Documents".
SetCurrentDirectory() doesn't seem to fail, and calling GetCurrentDirectory()
returns the right directory name, but CFileDialog just seems to be
completely oblivious of my directory change. This doesn't happen in Win98,
so I'm wondering if there's a reason why the behaviour changed in Win2k.
Another question would be: if SetCurrentDirectory() doesn't work in
Win2K, what does?
Thanks!
Steve

Use this...
CFileDialog dlgFile;
dlgFile.m_ofn.lpstrInitialDir = _T("C:\\Winnt\\System32");
the lpstrInitialDir variable is what controls where the file dialog starts in, and if its empty it will start in My Documents or whatever the default is.

I can't seem to disable a button, so that it is showed as grayed-over. However, if I call IsWindowEnabled() after attempting to disable it, it says that it is disabled. Disabling it by setting its property to disabled doesn't work either. It still shows itself as enabled when the app launches.
The button is on a dialog-bar, and I attempt to disable it via the following:
m_wndDialogBar.GetDlgItem(IDC_MY_BUTTON)->EnableWindow(FALSE);
Calling UpdateWindow() doesn't seem to help at all either.

I may be wrong here...as always.  But...
I think your on the right track, but using the wrong thinking. A dialog bar is a dialog...but its not really a Dialog in the normal sense of things. Its really derrived from CControlBar like CToolbar. I think.
Try treating your CButton's like standard everyday toolbar buttons and use GetToolbarCtrl. ie:
CToolBarCtrl& myControl = m_wndToolBar.GetToolBarCtrl();
myControl.EnableButton(IDC_MYBUTTON, FALSE);
I'm really stabbing at shadows here, so if I'm wrong I never posted this. If I'm right...you bet I posted it.

Unfortunately, that is not correct. You need to ON_UPDATE_COMMAND_UI handler for each button in the dialog bar, just like you would for a button on a control bar.
|
|
|
|

Yeah, Frank had the right idea. Because the button is on a dialog bar, you need to enable/disable it like it was a toolbar button. That is, you need to create an Update UI handler for it in your message map:
ON_UPDATE_COMMAND_UI(IDC_MY_BUTTON, OnUpdateMyButton)
And then in the handler, set the state of the button:
void CMyClass::OnUpdateMyButton(CCmdUI* pCmdUI)
{
if (i_want_the_button_to_be_enabled)
pCmdUI->Enable();
else
pCmdUI->Disable();
}
Hope this helps.

Hi,
Just having a quick play around with install shield. This has got to be a stupid question! I have added files to file groups. For example i added a link to notepad.exe to 'program executable files' group. Yet when i compile and run the installation, no files are installed, And zero K appers in the total file size for custom installation.
Anyone know where i am going wrong?
Cheers
Dave

We should add this to the FAQ, it gets asked so often. But it's a ftrstrating problem. In Installshield you essentially add your files twice - once to create a file group and another to add them to the current installation. I forget where, it's over a year since I used it, but if you've added them once, you've probably created a group but not made it part of the installation.

My program displays a complex layout of BMPs in the client window. When the client is inactive (i.e. when my program is out of focus), other window/folders which are being dragged in front of the client "smears" the window, leaving the ghost image of it.
As a "work around", I made a variable 'clientActive, and flag it when the window is active, and unflag it when the client goes out of focus. Then, in OnDraw, I set it so it redraws the client window when 'clientActive' is unflagged.
This "work-around" works, but the thing is that even a mouse cursor passing by the client window makes it redraw. The end result is that moving mouse over the inactive client causes major flickering as it's refreshing (redrawing) the client window everytime mouse moves. 
How can I correct it so that mouse movement doesn't cause refresh to occur, and still not have other applications' windows leave "smears" in my client?
Thank you

Moving the mouse pointer will always cause Invalidation - the probable question you need to ask is how are you handling your drawing ? Are you drawing your bitmaps to a memory DC and copying to the screen all in one go, or are you copying them a bit at a time ? Is the nature of the drawing such that you'd be better doing it in OnEraseBackground ( I assume you're using OnPaint because of the flicker ).
