For addition, you can change LPCSTR to LPCTSTR so that it will change to char or wchar_t automatically.

You will certainly get an error in VC++ 2008 for code such as: const char cc = 'C'; LPCWSTR lpcws; lpcws = &cc; error C2440: '=' : cannot convert from 'const FYI the Exmaple.cpp and the Example.h are error free! I would suggest you to regenerate the intellisense files in your project, maybe this can help you to solve this problem. Or use the WCHAR macro.
You also need to use WCHAR/wchar_t in place of char (where applicable) and call the wide versions of the Windows API. It will rebuild the sdf file. share|improve this answer edited Aug 27 '13 at 17:24 answered Aug 27 '13 at 17:04 Nathanael 1,4331124 Not all Windows APIs have two signatures, like UpdateWindow. The multibyte character setting has made this function expect LPCSTR not LPCWSTR. --- Another example --- WNDCLASSEX winClass; ZeroMemory(&winClass, sizeof(WNDCLASSEX)); winClass.cbSize = sizeof(WNDCLASSEX); winClass.style = CS_HREDRAW |
However, based on the code snippet which provided by WayneAking, there is a error message about “can not convert char* to LPCWSTR”. Browse other questions tagged c++ or ask your own question. Variable names starting with m_ are often used to denote class-member variables that should be defined within the GLWindow class in GLWindow.h. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed

You don't have to have a full understanding of UNICODE to use the corresponding types. Not the answer you're looking for? Everything compiles and runs. If the compiler/linker error only appear on VS2010 but not on VS2008, could you post a code snipping for us to repro this issue?
LPCWSTR stands for Long-Pointer Constant Wide STRing. this contact form They can not convert to each other, if there is no declaration about this. Does anyone have a fix for this? If you need further assistance, feel free to let me know.
Secondly, your class name is also wrong. To use ANSI/Multi-Byte encoding the call would be CreateWindowExA(NULL,"WNDCLASSEX",...). I have set the character set to multibyte, which resolves the first error, but intellisense doesn't seem to realize it. have a peek here Back to top #3 Assassinbeast Members -Reputation: 271 Like 1Likes Like Posted 10 October 2012 - 03:03 PM The L before a string literal means that the string should be
You can either set your solution to use ANSI encoding by changing Character Set (on the General node of the Configuration Properties) from Use Unicode Character Set to Use Multi-Byte Character MFC which seems to revel in side-effects. UPDATE 2: That solved al lot of errors!
To see what the code looks like after the preprocessor is through you can use the /P or /E compiler switches (assuming you're using the Microsoft Compiler). Are you saying the code doesn't contain such an assignment? If you're going to use C++ CLI, don't. Might as well go UNICODE now rather than dealing with the headache of of doing all the ANSI to UNICODE conversions later since COM is UNICODE only.

I gets all your texture budgets! Could you upload your project which can reproduce this issue, to the skydriver and provide the download link to us? Class member function expects to receive an additional hidden parameter called this, so the signature doesn't match. Please let me know if this helps!
I don't know what to think of C#. They should look like this -- LoadIcon(NULL, MAKEINTRESOURCE(IDI_APPLICATION)); The same is true for the small icon, i.e., the last one in your register class. If your compile options do not specify that you want to use wide unicode characters the windows API will assume you're using ANSI characters, hence the error you're getting.The tutorial probably Search: Advanced Forum Search Forums Programming Web Development Computers Tutorials Snippets Dev Blogs Jobs Lounge Login Join!

To support both character encodings the C/C++ preprocessor replaces the respective character types and API calls with the specific implementations depending on whether or not the _UNICODE and UNICODE preprocessor symbol Without opening the PHB, is there a way to know if it's a particular printing?
