Could it be possible that CreateProcessWithLogonW() only works for Local users? I tried it many times and it works only if the user is a local one!
It seems that a domain, can't be a other workstation(of course)!!

... you can check the security context, if you try to access files! At the error code you can see whether you have the needed rights or not!!

You are right, look:

From MSDN:
The user account must have Log On Locally permission on the local computer. This permission is granted to all users on workstations and servers, but only to administrators on domain controllers.

Umm... aren't you calling a wide character fn with single char strings? Mebbe leave off the dubya. ( Yes Ravi, its a word now...)

Oops - my bad - there is no non-wide char version - the strings are LPCWSTR. So, maybe just use the L prefix as in Phillips example.

Send data to text file after read from pipe?

19-Apr-02 23:55

I'm a VC++ newbie!

I am trying to read from a pipe and then write the data to a textfile. I can read from the pipe and put the data into my dialog but it won't write the data to a text file. I know that it is opening the file and it does write the test "hello's" but not data from the pipe.

Here is the code that reads from the pipe:

FILE *stream;
char buffer[1024];
.
.
.
stream = fopen( "number", "w" );
fprintf( stream, "Hello\n"); //This goes to the text file

//Read from the pipe
ReadFile(hReadPipe, buffer, 1024, &bytesread, NULL);
fprintf( stream, "Hello2 %s \n", buffer); //Hello2 goes to the text file but nothing else

//send the message from the pipe to the edit box.
SendDlgItemMessage(hDlg, EDIT1, EM_SETSEL, -1, 0);
SendDlgItemMessage(hDlg, EDIT1, EM_REPLACESEL, FALSE, (LPARAM)buffer);

fclose( stream );

For clarity and possibly function, I would switch and use only one form of all of the functions. I would switch to either CreateFile, ReadFile, WriteFile and CloseHandle or fopen, fread, fwrite, fclose to do your pipe and file handling.

I am not sure that you can use ReadFile to to read data when you open a file with fopen. I believe that you need to use fread and fwrite. To test this you should check the bytes read value from the ReadFile function and insure that it is the size that you expect it to be. I suspect that it will be zero.

There is one other possibility that there is a NULL at the very beginning of your buffer data, and fprintf does not want to display it that way, I don't know.

Splitter without Doc/View

Hi 2 All! I have following question: how can I properly use splitter window in project that created without Doc/View architecture support? Most evidently solution - add object of CSplitterWnd by hands and initialize them within OnCreateClient - fails in a couple mouseclicking Frown | :(

Application crash preceded by debug warning message "Warning: create pane without CDocument". Crash occurs in the internals of MFC-code: CFrameWnd::OnCmdMsg

P.S. Sorry for my rough English Smile | :)

Thanx, it almost works Smile | :)

But in this sample any objects of СSplitterWnd are absent at all!!! There is an "manually" implementation Smile | :)

. Unfortunaly I need sample based on CSplitterWnd solely.

need help drawing to a meta DC

At one point in my app, I have a bitmap and an enhanced meta DC I want to copy the bitmap into the meta Dc so that I can copy to the clipboard.

I can't seem to get this to work.

here is my code

if ( OpenClipboard(hdc) )
{
EmptyClipboard();

//create the metafile DC
CMetaFileDC * cDC = new CMetaFileDC();
cDC->CreateEnhanced(GetDC(),NULL,NULL,NULL);

//call draw routine here that makes GDI calls int cDC

// my bitmap is here!!

//close meta CMetafileDC and get its handle
HENHMETAFILE handle = cDC->CloseEnhanced();

//place it on the clipboard
SetClipboardData(CF_ENHMETAFILE,handle);
CloseClipboard();

//delete the dc
delete cDC;
}

I am stumped, any help appreciated

I think you might need to detach the metafile before deleting it:

cDC->Detach();
//delete the dc
delete cDC;

BTW: you might as well create the CMetaFileDC on the stack instead of using new.
Also BTW: It is possible to put bitmaps on the clipboard directly.

Thanks for reply but that didn't work.

I have captured one of my components and saved it in memory as a bitmap. The class that I am using to capture, saves it as a bitmap so I have no choice but to work with bitmaps.

I can already copy it as a bitmap to the clipboard and paste into other applications. That works great.

I want to now copy it into the clipboard as an enhaced meta file.

I have been trying to stretchBlt the bitmap to the EMF but that seems to work sort of but there is offsets and distortion that occurs.

I just want to know if there is a propper way to copy the bitmap to an Enhanced meta file.

I am really stumped here.

Are you asking how to do it?

If so, this is what you need to do:

// I would change this line 
// cDC->CreateEnhanced(GetDC(),NULL,NULL,NULL);
// to this:
cDC->CreateEnhanced(hdc,NULL,NULL,NULL);
// this will help avoid a memory leak with DCs.

//call draw routine here that makes GDI calls int cDC


...
// my bitmap is here!!

CDC      dcMem;
CBitmap *bmpOld;
// This creates a memory DC to use the bitmap with.
dcMem.CreateCompatibleDC(hdc);
bmpOld = dcMem.SelectObject(&cBitmap/*your CBitmap object*/);

BITMAP bm;
cBitmap.GetBitmap(&bm);
// Paint your bitmap at (x,y), for the same with and height as the bitmap.
cDC.BitBlt(x, y, bm.bmWidth, bm.bmHeight, dcMem, 0,0, SRCCOPY);

// Select the old bitmap into the memDC.
dcMem.SelectObject(bmpOld);

//close meta CMetaFileDC and get its handle
...

GoodLuck

Splitter between two controls

I have need to add a simple splitter between two controls (could be a CTreeCtrl and a CListCtrl, 2 ListCtrl's, etc) in a dialog box. They need to be both side by side, and one on top of the other (depeding on the dialog).

Is there an existing class that I can use that I am unaware of? If not, does someone have an example of how to get started on this?

Any help is appreciated.
