That looks like the remote strings are UTF-8 encoded. CString class has no direct support for UTF-8 decoding.

Drawing controls

I have a dialog-based MFC application with a static control that covers the entire surface and a smaller WebBrowser control. The problem is: when painting, the WebBrowser control is drawn before the static one and, as a result, becomes not visible.
Do you know how to establish the correct paint order?

You can change the Z-Order of the controls.
There is a relation between the Tab order and the Z-Order
but i dont remember if it is same order or reverse.

Just try changing the tab order and see.

If you look close enough at the message error, you will see the offending method SECMDIFrameWnd::FloatControlBarInMDIChild(class CControlBar *,class CPoint,unsigned long). Probably you're not including the .cpp where it is defined. If you want to locate where the method is used, do a global search on your project files.

Well, after a great help by you, I successfully list installed apps like in the "Add Remove Programs" control panel application. The next step is to uninstall them. The only solution that I came up with is to split the UninstallString value - in some cases the first part is the uninstaller, the second is command line to the uninstaller. But it doesen't work with all programs. I use ShellExecuteEx to start the process.
Any ideas how to set up things working with every app -> like "Add Remove Programs" app does?

Thanks,

Deian

I don't know about ShellExecuteEx, but CreateProcess accepts that you pass the whole commandline (with program included and all) in lpCommandLine and leave lpApplicationName set to NULL, sparing you the parsing.

List boxes / scroll bars

Hi all,

On one of my dialog's I have a list box, with assocated class member of type CListBox. The list box has the following styles checked in the properties Window of the IDE: Border, Notify, Horizontal scroll, Vertical scroll & No integral height; but when the list box is used, and text spans more then the horizontal view I don't get a horizontal scroll bar (I do get the vertical one correctly though).

Any ideas why? Confused | :confused:

Connection points and different process space

Hi,

I'm using Ms Word automated from my application, and in that instance of Ms Word, I insert from my app and ActiveX control ( that I have developed with ATL).

I my application I get the dispatch of my ActiveX control....

It's possible to connect to my sink interface in the ActiveX control ? ( I mean, receive in my app, outgoing events from the ActiveX), or is it impossible ?, I have read that the implementation of the connection points in ATL is not prepared for that? Is that true ?...

A code snippet about what I want to do ( quite standard thing...):

COleVariant vClassType = "MySinkSvr.PruCon";

Word::InlineShapePtr pShp =  m_pWord->GetSelection()->InlineShapes->AddOLEControl(vClassType);
Word::OLEFormatPtr pFmt   = pShp->OLEFormat;


TRY {
   LPDISPATCH pDispatch = pFmt->Object;
   m_pCon               = pFmt->Object;

   m_pCliSink = new CCliSink;

   LPUNKNOWN pUnkSink = m_pCliSink->GetIDispatch(FALSE);

   if(AfxConnectionAdvise(pDispatch, DIID__IPruConEvents, pUnkSink,FALSE, &_dwCookie)) {
      TRACE("Success !");
   } else {
      TRACE("Failure !");
   }

}

How can I do it for different process space ?, Thanks in advance, Greetings

Hi Joao !

Yes, I've been diving on that articles, a lot of times, but it seems that what I want to do is a little bit special Frown | :-(

.

Well, for me it´s normal. Just have my report ActiveX control, in Ms Word Pasted ( then I can control the look and feel, in my way, and update sinchronize...).

For sinchronizing, the problem is that the ActiveX it's inside Word, and I can not hook up the connection point to my EXE ( it seems that the proxy thing doesn´t work well, there is no marshaling or no conversion at all of the address... Frown | :-(

).

And the most funny thing come with this, take a look at "Q150431", to print my ActiveX in Ms Word, it uses the oold windows 3.1 metafile format, ... that´s another funny thing... I have enhanced metafile, and then what I got from the printer is crap Frown | :-(

... sh*tty microsoft...

Greetings

Hum, do a search on Microsoft ATL archives for EMF or WMF (put it on the "for" textbox) , there is some discussions on office not suporting EMF Confused | :confused:

and converting your printer output in the right format

look also on ATL Yahoo group and WTL yahoo group
these are the best places for look on COM/ATL information (lots of ATL experts in these 2 groups)

I know that it went ok if it returns NOERROR but it returns -2147023673 how do find out what this means? In the MSDN library it says it returns an "OLE defined error" if an error happens, how do i get that error description?

Thanks

Use error lookup
Tools->Error Lookup

Or in the debuggers watch window type [var with HRESULT],hr

How to convert HDC to Color Bitmap?

The "hDC" must have the image already? you can use the provide function to do that!

HBITMAP GetBitmapFromDC(HDC hDC, int x, int y, int nWidth, int nHeight, bool bCopyToClipboard /* = false */)
{
	HDC  hMemDC = ::CreateCompatibleDC( hDC );
	HBITMAP hImage = ::CreateCompatibleBitmap( hDC, nWidth, nHeight );
	HBITMAP hOldBitmap = (HBITMAP) ::SelectObject( hMemDC, hImage );

	// Copy DC - Actual image is "hDC"
	::BitBlt(hMemDC, 0, 0, nWidth, nHeight, hDC, x, y, SRCCOPY);

	// Copy Image to Clipboard
	if (bCopyToClipboard)
	{
		::OpenClipboard( AfxGetMainWnd() );
		::EmptyClipboard();
		::SetClipboardData(CF_BITMAP, hImage);
		::CloseClipboard();
	}

	::SelectObject( hOldBitmap);
	::DeleteDC( hMemDC );
	return hImage;
}

Good luck!
