Samoyed need a help regarding dwmapi.dll and DwmExtendFrameIntoClientArea function
Dear All, My compiled code asking dwmapi.dll, which is nowhere to find on my windows XP box. using dependency walker, it reports that the "c:\windows\system32\urlmon.dll" is looking for this dll, and the function name is DwmExtendFrameIntoClientArea.

glynnd Disapearing Colour window
I am using VS8 with SP1 and when i try and edit an icon or bitmap resource the colour window/toolbox disapears after it has been clicked on e.g. selecting a colour. Once it has gone it is very dificult to get it to reapear. I have the window to normally dock and when I have managed to get it to float it still disapears. Any suggestions Reagards Robin That doesn't work as I think as far as VS2005 is concerned it is visible. the only way I can get it to repear is by clicking on another source window and re clicking on the window containing the graphic to be edited. you can right-click on the edit window and choose "show colors window" in the p ...Show All
GSK_phili Abstract class object
i hav read in all books dat we cant create object of abstract classes.. . and reasons like they are too abstract to create an object.. .. i want to know more of these reasons why we cant create objects...... . . . . manish Nevermind about the memory stuff, I think the best answer is like what Marius indicated, the language designed to be so. Hi An abstract class is one that has atleast one pure virtual methods. Normally when an object of a class is created, the vtable is filled in with the address of the virtual methods, which is one of the reasons why an object for an abstract class cannot be created. Assuming that the related vtable entry is filled with null, this would cause a exceptio ...Show All

CraigC How to make a compiler link with __CxxFrameHandler instead of __CxxFrameHandler3
How to make a compiler link with __CxxFrameHandler instead of __CxxFrameHandler3. Is there is any option available. We are developing printer drivers for Vista Operating system, for the XPS print path, using PT/PC support. Problem: Though we could install the binaries on the Vista OS, we were not able to install the Vista binary set on a XP operating system. We have installed the .Net3.0 on XP Operating system. Issue: On investigation, we found that one of our DLL was referring to some functions like : * strcat_s, * _itow_s, * __CxxFrameHandler3, * _except_handler4_common The issue is that the above functions "are not" exported by MSVCRT.DLL available on XP SP2 OS. Build Setup: We are currently building the dll ...Show All
Umeshgopal C++ design capabilities
I want to create software that allows the end-user to create multiple copies of their own buttons on a scanned map which buttons can be rotated 360 degrees and linked to a database. I thus need libraries of code for rotate and also zoom functionality that I can incorporate. Can I get this done with C++ or any of the other Visual Studio programs If not, what software do you recommend I'll check out this DirectX SDK. I understand that C++ is a programming language but I don't want to waste a lot of time trying to learn a programming language that ultimately won't get me to where I want to get to. Not being knowledgeable in what are contained in C++ libraries is the reason I was consulting those of you who ...Show All
AdrianWoods Text field question
Hi Folks; I have a text field that gets its contents from a SetDlgItemText call. The text goes beyond the length of my text field so I was wondering if anyone can point me to a list of flags so that I may allow the user to read to the end of the text field. That did the trick. Thanks again! A text field, as in a label Consider replacing it with a read only edit box. That way the user can select the entire content. Again I confess my ignorance. Is there a website that has the flags necessary to accomplish this I'm writing my resource file by hand. Please remember to tag comments as answers if someone is able to help you.

Rick Hill PSDK/calc-sample, please.
Below is error when I try to build sample project: Calculator. I have VC++ express edition and sample is for that version of C++. I also have PSDK which I wanted to integrate with VC++ express edition by following instructions; but wanted to be sure VC++ express edition is working (which it is not) by using simple sample projects. Thank you very much for any assistance to get this sample project to run/compile. I plan to use VC++ instead of fortran for my research so I and other students/scientists may have a graphical user interface and ease of entering code. Assembly language was no fun but I got thru that. I would be grateful if anyone could point me to sample code to use in VC++ express edition (with PSDK integrated ...Show All
