How can I find out which code line causes the following linking error :
"
Linking...
Mainfrm.obj : error LNK2001: unresolved external symbol
"public: virtual void __thiscall SECMDIFrameWnd::FloatControlBarInMDIChild(class CControlBar *,class CPoint,unsigned long)" (?FloatControlBarInMDIChild@SECMDIFrameWnd@@UAEXPAVCControlBar@@VCPoi
nt@@K@Z)
"
thanks,
Aviv.

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.

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?

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  .
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... ).
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 ... 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 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
/Magnus
|
|
|
|
|
Thanks for the help, but what is it exactly i should type in the watch window?
Thanks
|
|
|
|
|
HRESULT hRes = SomeFunc();
then you would type
"hRes,hr" in the watch window
/Magnus

How to convert HDC to Color Bitmap?
I used from "CreateCompatibleBitmap" but output bitmap was monochromatic.
|
|
|
|
|
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 )
{
HDC hMemDC = ::CreateCompatibleDC( hDC );
HBITMAP hImage = ::CreateCompatibleBitmap( hDC, nWidth, nHeight );
HBITMAP hOldBitmap = (HBITMAP) ::SelectObject( hMemDC, hImage );
::BitBlt(hMemDC, 0, 0, nWidth, nHeight, hDC, x, y, SRCCOPY);
if (bCopyToClipboard)
{
::OpenClipboard( AfxGetMainWnd() );
::EmptyClipboard();
::SetClipboardData(CF_BITMAP, hImage);
::CloseClipboard();
}
::SelectObject( hOldBitmap);
::DeleteDC( hMemDC );
return hImage;
}
Good luck!

I have a bmp handle that gave it from open dialog.
How can I resize it and show in listview by normal size.

Did you try CreateCompatibleBitmap ?

I'm including MSHTML into my class definition like this :
#include <comdef.h>
#include <mshtml.h>
#pragma warning(disable : 4192)
#pragma warning(disable : 4049)
#pragma warning(disable : 4146)
#import <mshtml.tlb> no_auto_exclude
The problem is, that when i modify my .cpp file, compiler throws these errors :
.....manualdlg.cpp(18) : fatal error C1083: Cannot open compiler generated file: '.........\debug\mshtml.tlh': Permission denied
Error executing cl.exe.
Creating browse info file...
BSCMAKE: error BK1506 : cannot open file '.\Debug\ManualDlg.sbr': No such file or directory
But when i try to run compile again, it will finish without any errors, until i modify my .cpp again. So i always have to compile two times. Does anybody have some idea how to solve this, please ? (i'm using VC++ 6.0 SP2).
Thanks

It so happens that VC++ generates mshtml.tlh everytime you type a character is .cpp file. i don't know why but it happens like that. So turn off intellisense, this would fix the problem.

I turned off all checkboxes in Tools->Options->Editor in 'statement completion options' area, but it has no effect

I wrote the following functions to draw rotated (0, 90, 180 and 270 degrees) WMF. It almost works, the rotation itself seems to be correct, but the translation is not. I get WMF which is properly rotated, but it is placed in the wrong place.
Note, this function must work under NT 4.0/2000/XP.
What is the reason of this problem?

I have a class call CFileDog, it is derivered from CNALABase which uses a template member to store data to a file.
But whenever i run the program it crashes, i worked out that it wirks when CFileDog is used as a global, but inside a class or function it crashes,
Con anyone help.
Thanks

Without more info, it is hard to say what your problem is. A little code'd help a lot (definitions of the classes involved, crashing code, tc.)

Is the class going out of scope whilst you are still trying to call its functions or access its data.
