convert cstring to LPBYTE

[Cedric Moonen]

First important point: why do you want to do such a thing ? Are you aware about unicode/non-unicode ? If not, I highly suggest reading this article[^] before going further. Post also your code to see what you are doing wrong.

I want to convert a cstring into LPBYTE...

How are you doing it? Something like:

CString name("Name");
const LPBYTE lp = (const LPBYTE) (LPCSTR) name;

...but each time i convert it only first character get stored in the LPBYTE and rest of the string is truncated.

How are you verifying this? Is Unicode defined?

Hi .. thanks for prompt reply. I am getting a file in cstring and i want to parse. The parser take the data in LPBYTE format and file data contain few words in languge other than english thats why i am taking cstring to store it. But when i convert cstring to lpbyte only first character get stores. Meanwhile i am going through the link you have sent.

Yes .. i have also tried the method that you mentioned. I am parsing that whole data that comes in lpbyte but it shows only one character. During debugging I am verifying it also throughg watch window. Thanks

Could it be that you are feeding a unicode string to something that expects a simple ASCII string? Also note, that LPBYTE is porbably not recognized as a string by the debugger, thus it will only show you the pointer's value (the address it is pointing at) and maybe the one byte it is pointing at.

hi.. thanks for reply. You are right in your first point, when i convert cstring to string and than pass it to LPBYTE than whole data is being assigned and yes we can see the whole data during debug in lpbyte but during conversation from cstring to string data not written in english language being wrongly modified and there what i am getting problem. Thats why I am trying to convert cstring directly to lpbyte. Thanks

Then -as other people already pointed out- please show us how you actually do the conversion.

Try this.

BYTE string[MAX_PATH];

::WideCharToMultiByte(CP_ACP, 0, (LPCTSTR)cstring, -1, (LPSTR)string, MAX_PATH, 0, 0);

Thanks for reply.. i have tried your suggestion but it fails to convert character of other language. Meanwhile i found a workaround solution of this one.

Nice change to ACTUALLY see a code example that actually works... Too many times I have to weed out the trash where people don't have the common courtesy of showing an actual code example. They beat the dead horse to death without any clue to help those that aren't intimately familiar with all the ins and outs of C! Thanks "Superman"! :) --- Most of my programming of the last 5 to 10 years has been in Visual Basic where strings are strings. C++ has so damn many string types that it is very easy to get confused when converting the different flavors of strings to anything and back. If I had my way, more people would learn to program in Assembly where data is data and you have to determine what to do with it. My first programming job for the first 5 to 7 years was purely in Assembly Language. I learned a bunch of things very quickly that way. We all too lazy in the last 20 years it seems when programming.
