Hi,
You should post a bit of code, responsible for the process of service uninstall.

the code is below,all code i found to uninstall service like this:
void CService::UnInstallService(TCHAR *tcServiceName)
{
SC_HANDLE schService;
SC_HANDLE schSCManager;

if(lstrlen(tcServiceName)<=0)
return;

schSCManager = OpenSCManager(
NULL, // machine (NULL == local)
NULL, // database (NULL == default)
SC_MANAGER_ALL_ACCESS // access required
);
if ( schSCManager )
{
schService = OpenService(schSCManager, tcServiceName, SERVICE_ALL_ACCESS);

if (schService)
{
// try to stop the service
if ( ControlService( schService, SERVICE_CONTROL_STOP, &serviceStatus ) )
{
_tprintf(TEXT("Stopping %s."), tcServiceName);
Sleep( 1000 );

while( QueryServiceStatus( schService, &serviceStatus ) )
{
if ( serviceStatus.dwCurrentState == SERVICE_STOP_PENDING )
{
_tprintf(TEXT("."));
Sleep( 1000 );
}
else
break;
}

if ( serviceStatus.dwCurrentState == SERVICE_STOPPED )
_tprintf(TEXT("\n%s stopped.\n"), tcServiceName );
else
_tprintf(TEXT("\n%s failed to stop.\n"), tcServiceName );

}

// now remove the service
if( DeleteService(schService) )
_tprintf(TEXT("%s removed.\n"), tcServiceName );
else
_tprintf(TEXT("DeleteService failed - %s\n"), GetLastErrorText(szErr,256));

CloseServiceHandle(schService);
}
else
_tprintf(TEXT("OpenService failed - %s\n"), GetLastErrorText(szErr,256));

CloseServiceHandle(schSCManager);
}
else
_tprintf(TEXT("OpenSCManager failed - %s\n"), GetLastErrorText(szErr,256));
}

someone can help me or give me the reason?

Make sure that SERVICE_STOP_PENDING is reported by service in ServiceCtrl callback function for SERVICE_CONTROL_STOP code as well as proper timeout for service stop completion.

{
if(type == 0){//message (email)
return ".txt";
}else if(type == 1){//calendar
return ".ics";
}else if(type == 2){//contact

Changing the extension of the file won't adapt magically the contents of the file to the file format you are looking for. You need to follow the format which is required by the .msg file. You can have a look here[^], see if it helps.

I'd like to do "on the fly" compression during a recording from sound card.
I know how to record into PCM .wav file. I don't want to use codecs
to compress but LAME or oggenc external programs.
But still I can not figure out how to pass in data, I just got from sound card buffer, into for example LAME.
..somehow from stdin ?
I can not use lame dll, i need it more flexible.
Does anyone know some example?
Thank you

Moving Up to VS 2005

I have started using VS 2005 for my MFC C++ applications, however I get loads of warnings, mainly the use of strcpy.

Are they a simple guide for moving up to VS 2005, I am having problems with strcpy etc.

I get in a mess if I just change to strcpy_s.

Also keep getting told to use new options to suppress these warnings, but they dont seem to make any difference.

Any suggestions please.

Because it's unsafe. Use strcpy_s() instead.

Why? Can you work around it with a #define directive?

Thanks for your post. strcpy works in some places but not others.

If I use it here in this module I get an error:

strcpy_s(pchData, LPCSTR(signalName));<br />
<br />
1>c:\mcs_am_emu\am_emu\am_e\signaldlg.cpp(1135) : error C2660: 'strcpy_s' : function does not take 2 arguments

This confuses me!?!

That's because you have to specify length of the destination buffer. It's all about securing from buffer underruns.

strcpy_s(pchData, put_length_of_pchData_here, LPCSTR(signalName));

Reading tree-view control of frontpage

Prasann Mayekar11-Oct-06 0:57

frontpage has a option to open a web thru file-open web command.
it displays a tree view control. i wanted to read the text of the root node in the control. so i tried the following:

1) HTREEITEM htitem;
htitem=TreeView_GetRoot(hWnd); //hWnd is the handle to the tree control
2) char Buf[80];
TVITEM tvitem;
tvitem.mask=TVIF_TEXT | TVIF_HANDLE;
tvitem.hItem=htitem;
tvitem.pszText=(LPSTR)&Buf;
tvitem.cchTextMax=79;
3) SendMessage(hWnd, TVM_GETITEM, 0, (LPARAM)&tvitem);

but this fails. why?
following works:
1) int cnt=SendMessage(hWnd, TVM_GETCOUNT, 0, 0);
2) SendMessage(hWnd, TVM_SELECTITEM, TVGN_CARET, htitem);

if this works, why tvm_getitem fails?

can anyone help?
thanks

Just a guess, but I suspect that Buf needs to be on the heap.

char *pBuf = new char[80];
tvitem.pszText = pBuf;

Hi there

Its for extreme beginners, I think. I was expecting like how do I add some more controls in it, how do I make it work, etc. The article just shows how to make one SDI app. I will be thankful if you can provide me with the required. Thanks for your time. Please note that I have a fair knowledge of working with dialog based apps.
