Do you mean Task Manager's list of processes? Just out of curiosity, why would you not want your application to show up in this list?

He's writing spyware that he does not want the user to know about. If the user knows about it, the user can kill it.

Just as an example, you can add the following to a .reg file and merge it into your registry. Then from Explorer, right-click on your CD drive containing an audio CD and you'll see the newly added option.

Windows Registry Editor Version 5.00
 
[HKEY_CLASSES_ROOT\AudioCD\shell\calc]
@="&Calc"
 
[HKEY_CLASSES_ROOT\AudioCD\shell\calc\command]
@="calc.exe"

For non-audio CDs, a minor change:

[HKEY_CLASSES_ROOT\Drive\shell\paint]
@="&Paint"
 
[HKEY_CLASSES_ROOT\Drive\shell\paint\command]
@="mspaint.exe"

You missed the following at the top of the file:

I currently do not know of a solution for this. Perhaps Michael Dunn can help.

CreateProcess puzzle

ns28-Sep-04 1:47

28-Sep-04 1:47

I am launching off a console app (by pressing a button )using CreateProcess. I save the handle to this process and when I press the button again, I want to terminate the process if its already running and relaunch it. I put in debugging statements and indeed I get the expected correct output, but the console window is nowhere to be seen this second time around!

if(m_serverProcessInfo.hProcess)
{
    TerminateProcess(m_serverProcessInfo.hProcess, 0);
    if(fpLog)fprintf(fpLog, "Terminated server\n");
    m_serverProcessInfo.hProcess = 0;
}


int res = StartServer();

and

int CPMA2000Dlg::StartServer()
{
	int res = 0; 
	STARTUPINFO StartupInfo; //This is an [in] parameter
	ZeroMemory(&StartupInfo, sizeof(StartupInfo));
	StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
 
	StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
       // set the window display to SHOW
  
	StartupInfo.wShowWindow = SW_SHOW;

	if(CreateProcess( m_sPath + "fileserver.exe", NULL, 
		NULL,NULL,FALSE,0,NULL,
		NULL,&StartupInfo,&m_serverProcessInfo))
	{ 
	if(fpLog)fprintf(fpLog, "Started server\n");
        }

My logs:

Started server<br />
Terminated server<br />
Started server<br />

The first time I do see the console window (server.exe) but the second time though CreateProcess() succeeds again, I dont see the console window which disappeared at the TerminateProcess().

How shall I proceed to figure out the problem?
Thanks,
sb

Are you doing this in order to have a single instance of the application?

No. I need a fresh copy of the server each time the button is pressed.

When the button is pressed, two apps are launched: server.exe and my.exe. my.exe depends on socket info from server.exe. When my.exe ends, the user closes the my.exe window, but not the server window. Then when he presses the button again, i want the server.exe to exit and relaunch itself. I dont really want to instruct the user to close both the server.exe and my.exe before pressing the button again. BTW I just modified my app and had the main app send a socket message to the server.exe (if its still running) which tells it to exit. Then it launches it again. However once again, my server listens to and follows the instruction to exit,exits, says its restarted (logfile) but doesnt show up (and my.exe gets unhappy claiming its not running).
Thanks for looking into this,
sb

Have you checked the return code for the CreateProcess the second time round?

Yes. It returns true the second time around too.

It may be a race condition. Try stepping through the code and ensure that the server has gone away before moving to the code to launch it again.

If this is the case and all works when you slow it down you will have to wait for the process to terminate before trying to start it again.

I hope this helps

I neglected to mention that when I step through theres no problem. So with your insight I did Sleep(1000) and it works. Now I nervous about whether the time is enough from computer to computer. On mine its adequate without being noticeably slow. Is there some way to be certain of this barring a statistical survey?

Thanks,
sb

Re: Media Player Mini-Mode

Um, a single Sleep is not ideal for this sort of problem. As you rightly say it may not be the same on all machines.

I suggest that you send the close, wait a while then check that the process has gone away before continuing. If it hasn't wait a while again then check again. Repeat this a maximum number of times before issuing an error message saying that the server has stopped responding for instance (as it is possible that the server may not close for some reason).

How can I produce a toolbar on the taskbar, similar to the Media Player Mini-Mode or WinAmp Bar? I need to be able to add an edit field and a few buttons.

Thanks Ant. You pointed me almost to the right place. I found 'Desk Bands' in the advanced techniques. I wanted to put my app in the taskbar, as a new toolbar. Unfortunately this is about all of the information/examples that are available.
