This seems like a pretty softball question, but I always have a hard time looking up this function because there seem there are so many variations regarding the referencing of char and tchar. ...
I have a project that uses two third party libraries, both of which make use of TCHARs in their header files. Unfortunately one library is complied as multi-byte (call it library a), and the other is compiled as Unicode (call it library b). Now the way I understand it is that TCHAR is replaced by the precompiler with either wchar or cha...
I am trying to write cross platform i18n C++ code. Since most linux system prefer to use UTF-8 as the character encoding, I thought that I should use string on linux and wstring on Windows. Is tchar.h available on linux? What is an equivalent replacement on for tchar.h on Linux? ...
I have a TCHAR array in my C++ code which I want to assign static strings to it. I set an initial string to it via TCHAR myVariable[260] = TEXT("initial value"); Everything works fine on this. However, when I split it in two lines as in TCHAR myVariable[260]; myVariable = TEXT("initial value"); it bugs and gives a compiler error: ...
We need to pass a format _TCHAR * string, and a number of char * strings into a function with variable-length args: inline void FooBar(const _TCHAR *szFmt, const char *cArgs, ...) { //... } So it can be called like so: char *foo = "foo"; char *bar = "bar"; LogToFileA(_T("Test %s %s"), foo, bar); Obviously a simple fix would be t...
Please could someone explain why this does not work? char *test = "test"; _TCHAR *szTest = CA2W(test); And please tell me what I should be doing instead. Instead of giving me equal text, it's giving me: ...
how to convert to tchar[] to char[].. ...
std::wstring.c_str() returns a wchar_t*. How do I get from wchar_t* to TCHAR*, or from std::wstring to TCHAR* Thanks ...
hi For comparing strings in UNICODE versions is it advisable to use strcmp or _tcscmp? Thanks in advance ...
I have a class which returns a typed pointer to a "const TCHAR". I need to convert it to a std::string but I have not found a way to make this happen. Can anyone provide some insight on how to convert it? ...
So the GetWindowText is declared on MSDN as follows: int GetWindowText( HWND hWnd, LPTSTR lpString, int nMaxCount ); However for the code to work we have to declare the second parameter as TCHAR[255] WTitle; and then call the function GetWindowText(hWnd,Wtitle,255); The LPTSTR is a pointer to an array of tchar, so...
I have a class that defined a user defined operator for a TCHAR*, like so CMyClass::operator const TCHAR*() const { // returns text as const TCHAR* } I want to be able to do something like CMyClass myClass; _tprintf(_T("%s"), myClass); or even _tprintf(_T("%s"), CMyClass(value)); But when trying, printf always prints (null) ...
i want to enter a text into TCHAR* argv[], how its possible to do. OR how to convert from a character to TCHAR* argv[]. Please help char randcount[]="Hello world"; want to convert to TCHAR* argv[] ...
On platforms different than Windows you could easily use char * strings and treat them as UTF-8. The problem is that on Windows you are required to accept and send messages using wchar* strings (W). If you'll use the ANSI functions (A) you will not support Unicode. So if you want to write truly portable application you need to compile ...
I'm slowly starting to get the hang of the _T stuff in Visual Studio 2008 c++, but a few things still elude me. I can see the benefit of the flexibility, but if I can't get the basics soon, I think I'll go back to the standard way of doing this - much less confusing. The idea with the code below is that it scans the parameters for -d a...
I have inherited the following line of code: TCHAR temp[300]; GetModuleFileName(NULL, temp, 300); However, this fails as the first 3 bytes are filled with garbage values (always the same ones though, -128, -13, 23, in that order). I said, well fine and changed it to: TCHAR temp[300]; ZeroMemory(temp, 300); GetModuleFileName(NULL, tem...
What are the various differences between the two symbols TCHAR and _TCHAR type defined in the Windows header tchar.h? Explain with examples. Briefly describe scenarios where you would use TCHAR as opposed to _TCHAR in your code. (10 marks) ...
In my application i'm declaring a string variable near the top of my code to define the name of my window class which I use in my calls to RegisterClassEx, CreateWindowEx etc.. Now, I know that an LPCTSTR is a typedef and will eventually follow down to a TCHAR (well a CHAR or WCHAR depending on whether UNICODE is defined), but I was wond...
I'm porting a library from char to TCHAR. the count parameter of this fragment, according to MSDN, is the number of multibyte characters, not the number of bytes. so, did I get this right? My project properties in VC9 say 'use unicode character set' and I think that's correct, but I'm not how that impacts my count parameter. _tcsncmp(ac...
I'm modifying someone else's code which uses TCHAR extensively. Is it better form to just use std::wstring in my code? wstring should be equivalent to TString on widechar platforms so I don't see an issue. The rationale being, its easier to use a raw wstring than to support TCHAR... e.g., using boost:wformat. Which style will be more c...
