But I can not add debug information of lib file to debug information of my project. I have the source code of lib file also. If you know how I can remove this error please let me know. Regards Monhi Re: A Question about lib files Jonathan [Darka]23-Jul-07 21:42 Jonathan [Darka] 23-Jul-07 21:42  What happens when you try to debug ? What error are you getting ? Jonathan Wilkes Darka[Xanya.net] Re: A Question about lib files mt_samiei23-Jul-07 21:54 mt_samiei 23-Jul-07 21:54  I should remove "Use program database" option to compile the code, In this situation I cannot debug the program. If I make that option active then I get following error. atapid.lib(tapireq.obj) : fatal error LNK1202: "D:\users\TCMon_1\Debug\vc60.pdb" is missing debugging information for referencing module I should find one way to add debug information of lib file to project which I want to add lib file to that. Regards Monhi Re: A Question about lib files Jonathan [Darka]23-Jul-07 22:09 Jonathan [Darka] 23-Jul-07 22:09  Have you tried rebuilding the entire project, just in case things have gotten a little confused ? regards, Jonathan Wilkes Darka[Xanya.net] Re: A Question about lib files mt_samiei23-Jul-07 22:13 mt_samiei 23-Jul-07 22:13  Yes I do it But It does not work. Several times I do it. Re: A Question about lib files Rajkumar R23-Jul-07 22:30 Rajkumar R 23-Jul-07 22:30  Hi, I think this is because both the application and library refers to the same debug info file "VC60.pdb" and build seperately causing only the application's debug information stored. Since you have the code for library, in the project setting change the Debug database file name to the project name, say atapid.pdb rather than vc60.pdb. or do the same for your application yourApp.pdb. Best regards Rajkumar Re: A Question about lib files mt_samiei23-Jul-07 22:36 mt_samiei 23-Jul-07 22:36  May you please give me the place which I can change debug information file name in visual C++ 6.00. In which menu. Regards Monhi Re: A Question about lib files Rajkumar R23-Jul-07 22:43 Rajkumar R 23-Jul-07 22:43  In project->settings->link(tab)->customize(in category list box)->program database name(edit box) Re: A Question about lib files mt_samiei23-Jul-07 22:48 mt_samiei 23-Jul-07 22:48  Thank you for your help. Re: A Question about lib files Md. Ali Naser Khan24-Jul-07 0:23 Md. Ali Naser Khan 24-Jul-07 0:23  Run the source code of the lib file in debug mode. Use the created lib file in your project and rebuild the project. Now I think you can debug the lib from your project. Tooltip for disabled control Hans Dietrich23-Jul-07 21:17 Hans Dietrich 23-Jul-07 21:17  If you have a control that normally has an associated tooltip, what would you expect to happen if the control was disabled? Should the tooltip still be shown? Best wishes, Hans [CodeProject Forum Guidelines] [How To Ask A Question] [My Articles] Re: Tooltip for disabled control Jonathan [Darka]23-Jul-07 21:21 Jonathan [Darka] 23-Jul-07 21:21  Hi Hans, I've seen disabled controls both with and without tooltips, but if I was coding it I'd be tempted to show the tooltip anyway. regards, Jonathan Wilkes Darka[Xanya.net] Re: Tooltip for disabled control Abhijeet Pathak23-Jul-07 23:10 Abhijeet Pathak 23-Jul-07 23:10  Yes, definitely... If a control, or menu item is disabled but still shows Tooltips, then it gives a good idea of what that button does and saves precious time as we don't have to look into help files...

Yes. Ravindra_Joshi wrote: If yes then what will be the value of pSrcDc :- Pointer to the source device context. That would be a memory DC that you've selected a source bitmap into. To create a bitmap with an array of pixel bits, you can use CreateDIBitmap() or CreateDIBSection().

I painted the Bitmap on the window by using a series of function as follows... CreateBitmap()-> To load the Bitmap from memory to CBitmap object. CreateCompatibleDC(),SelectObject(),BitBlt() -> actually put the Bitmap on the screen ( Window created by CreateWindow() ) ... Now I want to make a color of the Bitmap Transparent... I used TransparentBlt().... in pHdcSource and pHdcdstn parameters I passed the CDC* of the same parent window on which the Bitmap is painted.But the function returns a FALSE value... What to do... ? Re: Can TransparentBlt() be used for Bitmap Bits stored in array ( Bitmap stored in memory) Ravindra_Joshi25-Jul-07 0:08 Ravindra_Joshi 25-Jul-07 0:08  The BitBlt() is as follows.... BitBlt(Pdc.m_hDC, 10, 10, 16,15 ,MemDC , 0, 0, SRCCOPY); Pdc.m_hDC -> HDC of Target window.... TransparentBlt(Pdc.m_hDC,10,10,16,15,Pdc.m_hDC,10,10,16,15,RGB(128,64,0)); passed Pdc.m_hDC to hdcDest, ( parameter no. 1 ) passed Pdc.m_hdc to hdcSrc, ( parameter no. 6 ) Ravindra...

Now i added that feature in that by commenting a single line in my precreatewindow function in Childwnd class. I get the buttons and i can minimize the window.But i minimed the window,when i maximize it fit it to system size (like multiple window in VC++ coding page) and after that i cannot minimize or maximize or close the window. Whats the wrong with that?
