Hi euacela

I have a MFC dialog box program, and all it is does is ping other computers and display the results. Right now I'm calling my function to ping from the OnInitDialog function. Therefore this executes the ping function before the dialog box pops-up causing a delay for the dialog to show up. Is there anyway I can pop-up the dialog box first, and then automatically call my ping function (without having to hit any buttons)?
Thanks

Make a button handler for the ping operation and then post your dialog a message to itself simulating the button click. That would do it. Or create and process your own registered message - post it to yourself from the OnInitDialog.

Thanks, PostMessage is what I needed.

Hi,
I am stuck up in the middle of killing a process created using CreateProcess within a DLL. While using ExitProcess with the crated process's exitcode, it is terminating the parent process too. Is there anyway to kill a process created within a DLL without disturbing the parent process?? . BTW the process that is craeted is an exe file of a console application.
thanks,
-Pav.
Got it, nevermind by using terminate process with process handle that was created

well
you should do it with terminate process
but when opening the process and obtaining the handle you should open it without inheritting from parrent.
OpenProcess(
DWORD dwDesiredAccess,
BOOL bInheritHandle,
DWORD dwProcessId
);
DediredAccess should be PROCESS_TERMINATE
and bInheritHandle should be FALSE
Then terminateprocess should do the job easily;

OpenProcess hmmm... will give it a try sometime... Thanks for your time though..

Although the practice is rampart - in general it is not safe to go around calling TerminateProcess on processes. This API kills the process on the spot and as such the application doesn't have a chance to clean up after itself. For example it may result in temporary files not being deleted, files or registry entries in a corrupt state as a result of the process being terminated in the middle of an update or worse.

Yep, you are right. But, depending upon the application I think we can go in this way  to get around the problem. But in intensive applications this is not something that is recommended as you said. But, for me, this is good enough as I am using to start and stop NI-Board.

Hi All,
I need help with the list boxes.I am working with Dlls.
Okay so what I want to do is: I created a list box with some items in it.
For example: FDK01, FDK02...FDK09 means key F1, F2.....F9. Now, I want to perform something like when I select FDK01 in the list box and then say OK ..it should then allow me to pressed button 1. How should I code the list box item to perform what I want?
Thanks in advance

Though it's not very clear from ur question but, I guess whenever a list box item is selected & user presses Ok button u want some other button to be selected. is it??
u can use SetFocus method for that

You can use SendInput for this purpose.

I'm trying to write a program that takes input and instantly sends it to multiple windows simultaneously. Ultimate goal is to have 5 copies of Notepad open, typing into one, and the program fills out all 5 Notepad windows without ever changing focus from the initial window.
Unfortunately, I dont understand how to accomplish this because everything I read tells me that you must activate an application beforing using SendKeys or SendInput.
Anyone have some ideas? Has this been done before?

Send WM_KEYDOWN, WM_CHAR and WM_KEYUP messages (in that order) directly to the notepad windows. You don't need to emulate a keyboard - just tell them that a key has been pressed.

Hi I'm currently trying to code a REAL-TIME midi remapper program in Visual C++ using MFC..
I need the program to constantly look for a input midi signal... The only way I have figured out how to do this is to run a constant loop that contains the midipoll(); I've had to set it to only recieve a certain number of signals so it will eventually end.
I works great and recieves all of the messages.. but while in this loop I loose control of the rest of the program... The loop takes over. Is their a way I can do this without loosing control of the program?

Put that processing into a secondary thread.

Thanks.. that worked out great using a work thread...
Now i'm having a problem accessing the UI from within the thread.. ie. a listbox
I need to send info to the listbox from within the thread.. Any Ideas
this is what I got...
UINT MyThread( LPVOID pParam ); //prototye
UINT MyThread( LPVOID pParam )
{
while(RunThread) {
If (inputdetected){
m_ListBox1.Additem("input detected"); // <-- I don't have access to ListBox 1 from withing this thread.
}
}
return 0; // thread completed successfully
}
I call the thread to start with..
AfxBeginThread(MyThread, NULL);

You can not use the MFC control placeholders from the thread.
Instead, it is better to use the listbox control's window handle directly to add elements to the listbox.
The LPVOID pParam passed to thread could be a data structure, in that data structure, one of the fields could be the window handle for the list box control.
So you call
typedef struct {
HWND hListBox;
} MYSTRUCT ;
MYSTRUCT MyThreadInfo;
MyThreadInfo.hListbox = m_ListBox1.m_hWnd;
then
AfxBeginThread(MyThread, &MyThreadInfo);
UINT MyThread( LPVOID pParam )
{
MYSTRUCT* pMyThreadInfo = (MYSTRUCT*)pParam;
while( RunThread ){
if( inputdetected ){
SendMessage(pMyThreadInfo->hListbox, LB_ADDSTRING, 0, (LPARAM)"input detected");
}
}
return 0; // thread completed successfully
}

This is driving me nuts. I'm trying to call CreateProcess() to start Internet Explorer from within a Manifest-enabled (specifically Common Controls 6) application and I get about 7 dialog boxes that say the exact same thing:
------------------------------
Runtime Error!
Program: C:\Program Files\Internet Explorer\iexplore.exe
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
['OK' button]
------------------------------
After I click through all 7 'OK' dialogs, everything seems to work normally.
The only thing that I've discovered searching Google is that XP Manifests for Common Controls 6 is what seems to be affecting Internet Explorer's startup sequence. CreateProcess() is acting like "if the process starting the new process is XP Manifest enabled, then the new process MUST ALSO be XP Manifest enabled." Now, I know there has to be a workaround because Explorer.exe is XP Manifest enabled and runs new processes all the time (including IE).

1) Use CreateProcess() to start another process besides iexplore.exe.
2) Remove the manifest from your project and then try to start iexplore.exe.

I figured out what the problem was. Well, not EXACTLY what the problem was, but it had to do with sending an incomplete set of environment variables to the new process in the CreateProcess() call.
Thanks anyway. The error message had very little to do with the actual problem (which is what was so strange). Apparently IE relies on the Visual C++ libraries in some way that is dependent on the environment variables passed to it.

I need to know how to control a directory structure from the "Open" dialog window from an application. I need to be able to restict the user from going to directories that have been determined they should not enter and restrict them to a certain directory. Anyone have any idea how to do this not in MFC, win32 api format.
Thanks,
|

You can restrict them to a single directory using the OFN_NOCHANGEDIR flag. If you need something a little more complicated then create your own OpenFile dialog.
