CString to TCHAR & TCHAR to CString

[Paulraj G]

hi... i have to get a string via text(edit)box. then i have to convert it to TCHAR. because my operation should be do in TCHAR. then i have to do some operation. last i to covert once again it to string and display in a edit box. please anybody can help me? regards, Paulraj.G

You already asked this question yesterday, what was the problem with the answers ? Anyway, a very complete link about CString management (and how to convert them) can be found here[^]

No need to shout. What did you do exactly ? Post some relevant snippet of code.

Just a quick sample though I think it might be on a brute-force approach. I had problems with TCHAR though, it has some trash characters at the end. TCHAR* tchar; CString message("Hello there"); int temp = message.GetLength()*2; //multiply by 2 because of the CString format tchar =(TCHAR*)malloc(temp+1); //add 1 for the NULL at the end: but doesn't work memset(tchar, NULL, temp+1); memcpy(tchar, message, temp); //copy; now we have the TCHAR //assign the tchar to the CString CString messageback(tchar, temp/2); //divide by 2 since it's the actual number of characters free(tchar); Sorry but still a problem with TCHAR's variable as there are "trash" characters on the end. Maybe others can help. :) Read this article here -- modified at 18:50 Wednesday 7th November, 2007 ouch! sorry bout that. admittedly, I did not really took that much attention to the article. comments noted. lesson learned.

Probably you made mistake(s) on that way, maybe posting your code snippet will help. :)

Honestly, I think you've to read (perhaps with more attention ) the article too (and, maybe, related MSDN documentation). Don't blame me for this. :rose:

Why multiply by 2 ? How do you know that a character is 2 bytes long ? It's only the case when UNICODE is enabled.

tchar =(TCHAR*)malloc(temp+1); //add 1 for the NULL at the end: but doesn't work

Don't use malloc in C++. If you had used new, you won't have any problem with calculating the size. You just create an array of TCHAR and the compiler will allocate the correct size depending of UNICODE is set or not.

memcpy(tchar, message, temp); //copy; now we have the TCHAR

Don't use memcpy to copy strings. Prefer to use the macro _tcscpy that will be strcpy if UNICODE is not declared or wscpy if UNICODE is declared (so you don't have to bother about it). If you have garbage values at the end of your string, it's simply because you didn't put a ending zero at the end of your string.

I'm not getting what you are trying to do with the code. CString is just a wrapper for TCHAR. That is CString has a member variable like below. CString { private: TCHAR *m_buf; //Several other stuffs! }; if your intention is to construct another CString from the edit box contents then CString messageback(message) will suffice. to get the pointer to member variable m_buf(member variable name might not be exact) by using GetBuffer() method. pratap

you are writing pure crap, and you think it's a correct answer for someone that is lost with his code ? read here[^] for how to consert from one type to the other (and benefit of the whole linked thread to read it, it could be useful for you too)
