ERROR 'strcpy' : cannot convert parameter 1 from 'TCHAR [20]' to 'char *'
-
There is a boatload of CRT string manipulation functions. You can be kind enough not to add a query here for every single function that is referred to in your code. Just get to the documentation page[^] and click on the function that you're using. Then, choose the generic text mapping routine version (tchar.h routine) of that function. As an example, choose
_tcsdecinstead of_strdec. You might want to read about Using Generic Text-Mappings[^].It is a crappy thing, but it's life -^ Carlo Pallini
Code Segment is token=strtok(userid,_T(";")); What about this error? 'strtok' : cannot convert parameter 2 from 'const wchar_t [2]' to 'const char *'

Is it really that difficult? Read my previous reply to you again. Go to the documentation page and click on
strtokand choose the generic text mapping routine equivalent instead. You need to read on Unicode, Generic Text mappings, Internationalization, and string manipulation. You really need to.It is a crappy thing, but it's life -^ Carlo Pallini

I have changed that. Now the new error is 'wcstok' : cannot convert parameter 1 from 'char [1000]' to 'wchar_t *' what should I do now?

You are looking for someone to give you an 'instant fix' (not to mention you post a query for every error of the same type) without even understanding your problem properly, which is essentially not going to help you in the longer run. I am wanting you to understand the basics so that you will be able to solve the problem yourself. Therefore, do what Cédric asked you to do[^]

I'm not getting that what to do? Plz help me. thanks.

Look, people here are willing to help but if you don't want to put any effort yourself, then you can forget about it. The article I linked to you contains a lot of information about unicode and non-unicode builds. Once you have read the article, you will understand that to support both unicode and non-unicode builds, you will need to use TCHAR (and not char) and all the unicode-independant string manipulation routines (instead of strcpy, strlen, strtok, ...). For ALL of those functions, if you look in the MSDN documentation, you have a table that compares the different versions. You always have to use the "TCHAR.h routine" version.

Would that be rather character set independent string manipulation routines? OK, I'm just being a nitpick. :-D

To be honnest, I didn't know the exact terminology. Now I know :)

It looks like you're doing a UNICODE build, but, neverthless, userid is declared as
char *(orchar userid[]) insetad ofTCHAR *and, moreover, you're not using the generic text equivalent ofstrtok(i.e._tcstok). :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke

If it is 'strlen' : cannot convert parameter 1 from 'TCHAR [20]' to 'const char *' then what to do?
As someone else mentioned, it looks like you have some mixed UNICODE and ANSI problems. Ti make the code portable, make sure you have included "TCHAR.H" and use _tcslen instead of strlen. That should fix the problem. Tony
