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.

Hello All
Actually i found an article on codeproject for exporting messages from outlook in text form now i want that messages should be .msg type .I simply changed this function given in the code too
const char* typetoext(long type)
{
if(type == 0){//message (email)
return ".txt";
}else if(type == 1){//calendar
return ".ics";
}else if(type == 2){//contact
return ".vcf";
}else if(type == 3){//task
return ".ics";
}else{
return 0;
}
}
const char* typetoext(long type)
{
if(type == 0){//message (email)
return ".msg";
}else if(type == 1){//calendar
return ".ics";
}else if(type == 2){//contact
return ".vcf";
}else if(type == 3){//task
return ".ics";
}else{
return 0;
}
}

Can anybody help me in doing this

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.

One way is to derive the view from CFormView.

Might I suggest a very good book (softcover) called 'Beginning MFC Programming', by Ivor Horton. This book has an excellent tutorial in it and explains things very well.
