I'm trying to write the TESTCOMMANDS project (from the This Party Commands tutorial in tech docs in the help, using Visual Studio Express with the Platform SDK installed, and a few tweaks to config files to allow DLL creation from the wizard), but the MessageBox command is failing (says MessageBoxW cannot convert LPSTR to LPCWSTR or something). So, to get round that compile error, I try to use LPCTSTR or LPCWSTR which then compiles up okay, but when I test it in DB-Pro, I either get an error message, or the MessageBox that pops up is full of garbled gibberish!

The 'GetValue' one works fine.

I'm certain I am doing something stupid, or maybe I've set something up wrong with VS Express.

Does anyone know what I'm doing wrong? Am I the only one who has had this problem? (I did some forum search but couldn't find anything).

Thanks.

Sounds like your using Unicode character set option instead of multi-byte. Change it in the project settings.

You're right. I've changed it, but it still doesn't like LPSTR.

I'm also getting warnings that UNICODE specified for my pre-compiled headers but not for current compile now.

Also, why can't I use CString!??!? It falls flat on it's face!

ARGH! This is bugging. Maybe I should just find VC6? Would that help? This 'Express' edition is giving me a headache! (If it's that that's causing the problem).

Unmanaged C++ is like the usual stuff like mfc/win32 etc etc.... Managed C++ uses the .net framework and can be easier sometimes.

Dont use pre-compiled headers - they are more trouble than they are worth.

I dont know whether you can use MFC with the Express version - you should have had the option when creating the project (its also in the project settings).
