• David S. Anderson Giving the user a language option in VC++??

  Hello, Could any one please explain how it is possible to give the user the option to change the language of the status bar,main frame etc during runtime I create a dialog box in an SDI based MFC-application(using Visual Studio dot net 2003) and have a list box in the dialog box,with language options such as "English","French","German" etc.The default language is english,but if the user selects German,then on pressing ok the language should change to german.

• pfunkmasterflex MFC Question

  (I cannot find a MFC forum here so I thought this would be the best place to post) I'm writing a program in C++ using VS.NET 2005 with the DOC/VIEW approach.

• Mike L Hayes We cannot have static friend function?

  Hello everybody I tried a lot.. and Searched on NET ... but din't get the answers.. why friend function can't be static or extern I got the answers I am not satisfied with this answers. actually this answers is hard to digest. We cannot have static friend function...is it because 1.since static member functions can access only static data members...whereas friend function can access all the members. 2.friend function also require an object to access the members...wheeras static member functions can not. 3.One more thing....since friend functions are non-member functions....and static functions are member functions And Another question is Why Static member function can't recieve this Pointer ...Show All

• Peter Torr - MSFT Help button get chm instead of hlp

  I have a application built around a CPropertySheet derived class. The help button is looking for 'app.hlp' file (this is the default MFC stuff, I've not added anything other than moving the button). How do I get it to look for a 'app.chm' file instead I've tried the following using a test help file in InitInstance() //First free the string allocated by MFC at CWinApp startup. //The string is allocated before InitInstance is called. free((void*)m_pszHelpFilePath); //Change the name of the .HLP file. //The CWinApp destructor will free the memory. m_pszHelpFilePath=_tcsdup(_T("C:\\filezilla\\filezilla.chm"));     EnableHtmlHelp(); but i just get "Failed to launch help" Note that you ...Show All

  I have the following code: typedef void* STACK; template <typename T, void (*S)(T* ptr)> class AutoPtr { public: int junk; }; template <typename T, void (*S)(T* ptr)> void FreeStack(STACK* stack) { // loop through all stack items and call S on each item } template <typename T, void (*S)(T* ptr)> class AutoStack : public AutoPtr<STACK, FreeStack<T,S> > { public: int junk; }; typedef void* RESOURCE; void FreeRESOURCE(RESOURCE* res) { // free the RESOURCE } int main() { AutoStack<RESOURCE, FreeRESOURCE> a; a.junk = 0; } Basically, I pass various free functions through the template.

• Ramazan Acar .dll entry point

  Hi folks, I've been porting my code over to VS 2005 from VS 2002, and have been confronted with what appears to be a new addition that has me stumped. I'm compiling .dll's and am getting errors when attempting to use them along the lines of: "The procedure entry point _encoded_null could not be located in the dynamic link library MSVCR80.dll" Now, MSVCR80.dll exists (I had to put it on the machine myself, though), so I figure this leads back to the linker in VS 2005. I've noticed a new option referring to Entry Point and also the ability to set the /NOENTRY switch. I've not specified an Entry Point, and nor have I specified the /NOENTRY switch. Obviously this probably explains what I am seeing, right Not specified an entry point. ...Show All

• dmk70 Converting from C to .NET C and to .NET C++?

  Newbie here. Not sure I have lost track. But I am really confused now. I have a C program and have open it with .NET VS2005. Some conversion has automatically done and now it is successfully compiled under the .NET environment. However, the file is still remained as a *.c file. I am not able to use some .NET functions like Console::WriteLine. I supposed I need to further convert it to a *.cpp file What should I do to fully convert an ANSI C program to a full .NET C++ program Please enlighten me. I promise to grade your posting. Thank you very much. There's very little hope you can ever directly translate a 'C'-style socket app to .NET, there's just too many operating system specific ca ...Show All

• hemo Running an external .exe from C program

  Hi, I want to run an external .exe file from my C code. If i use "system" command the external exe runs in the same window. How can i run the child exe in a different window Thanks Karthik Alternatively, you could use CreateProcess, with the creation flag CREATE_NEW_CONSOLE. See http://msdn.microsoft.com/library/en-us/dllproc/base/createprocess.asp frame=true for more information. Of course, that would depend on *nix portability. Maybe instead of system("MyExternalExe.exe"); you should try this: system("start \"My external EXE\" MyExternalExe.exe"); I hope it helps. ...Show All

• Heinz_Richards Problems using _fseeki64 and _ftelli64

  Hi, I am using VS 2003 and i need to call _ftelli64 and _fseeki64 in my application. However i am getting linker error error LNK2019: unresolved external symbol __ftelli64. Are these functions exported for VS 2003 build applications. Please suggest any solution Thanks MM Ansari I need to code in "C" so C++ functions (tellg) won't be of help. Is there any way i can still use _telli64 of file and not lower-level file. I tried using _lseeki64(_fileno(fp), 0, SEEK_CUR); but even this function returns me end of file. The method based on _telli64 actually gives the file position of underlying lower-level file. The FILE -based functions use a buffered i/o, therefore the results of _telli6 ...Show All
