Hi,
I'm trying to create a little program, wich basicaly reads a file. I already have written some code in the serializing-fuction, wich reads the data. I now would like to add a progress bar and some info-text in my window (CFormView). I don't know how to get data from the doc class to the view class. Has it something to do with messages? I'm new at all of this stuff, so its very confusing...
Thank's in advance!

You can simply use CDocument's GetFirstViewPosition() and GetNextView() to access the desired view.
An alternative for frame windos is calling AfxGetMainWnd()->GetActiveView(), which gives you access to the current view.

After the document has successfully loaded the file, simply call UpdateAllViews() to notify the view that it needs to display new information. In the view's OnUpdate() method, it will ask the document (usually via GetDocument() and one other method) for the data to be displayed.
Check out the Scribble tutorial on MSDN. It goes over serialization, and doc/view in great detail.

I'm assuming you've made five calls to CreateView(). To access one of the views, just call GetPane().

Hi Jain
Sorry for the delay
Here i do consider that i am having two panes ie two views, first the CCallManagerView(0,0) and the other CUserView(1,0). So when i do need to set some value to the CCallManagerView's control from CUserView, i'll be using the following code
void CUserView::SetValue2Manager(void)
{
CMainFrame *pMainFrame = (CMainFrame *) GetParentFrame();
CCallManagerView *pView = (CCallManagerView *)pMainFrame->m_wndSplitter.GetPane(0,0);
if (pView)
{
pView->myEdit.SetWindowText("Hai From Call Manager");
}
}
Hope this may help you. If you want the CUserView then use GetPane(1,0)

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?

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:
Windows Registry Editor Version 5.00

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

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;
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ;
StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
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
