Convert TCHAR[][] to char*?

[Gunaamirthavelu]

Hi folks

I want to convert TCHAR[][] to char* and TCHAR[][][] to char*. help me.

[cilu]

That do you mean? char[][] and char* are not the same, less char[][][] and char*.

[dave2k]

TCHAR tc[2][2];
char* pChar;
pChar = (char*)&tc;

sorry cilu i didn't get u.

TCHAR tc[2][2];
char* pChar;
pChar = (char*)&tc;

i try this code but it onlt take first char only.

Hi

I have solution for this problem ,

VOID ChartoTChar(TCHAR *CBuff,CHAR *Char)
{
while((*CBuff++ = (TCHAR) *Char++) != '\0');
}

void WcharToString(char * str,TCHAR* pTchar)
{

while( (*str++ = (char)*pTchar++) != '\0') ;
}


It will usefull for u.

And what does this have to do with the question?

Well, I didn't get you either. Perhaps you should explain what are you actually trying to do. You want to convert and array or arrays of chars to a pointer to char and an array of arrays of arrays of char to pointer to char. What do you want to do?

Why do you feel the need to perform this conversion?

Please post the code where (you think) such conversions are necessary.
We here might have another opinion...

 i want to read file from WMS_20060823.log and write to write.txt file. u can use this code only but u can convert the datatype for writing the file.

Yes, it is real pain in the back, especially when you adopting old code with long main function.
The simplest way is to allocate new space for strings and copy characters skipping each second character. Here is the CPP code that duplicates _TCHAR * argv[] to char * argn[].

http://www.wincli.com/?p=72

If you adopting old code to Windows, simple use define mentioned in the code as optional.

int _tmain(int argc, _TCHAR* argv[])
{
char ** argn = allocate_argn(argc, argv);
#define argv argn
// Here is your old code working with arguments
if (argc>1) {
printf(“Arg 1 = ‘%s’\n”, argv[1]); // Just argn intead of argv
}
#undefine argv
release_argn(argc, argn);
return 0;
}

Why do you revive this more than four years old thread?
Only to post a piece of wrong code to it?
