Thanks Nemanja,
What is the root cause why stdcall does not support variable number of input parameter? Maybe from generated assembly, we could find out?
(I think both caller and callee could get # of input parameters from stack in theory?)
regards,
George

You can see the detailed explanation in the article. Basically, stdcall functions have to clean up stack themselves (as opposed to the caller function) and at compile time they have no knowledge how many parameters are there going to be passed.

Doubtful. There was some speculation a while back that he is not even human, that he is a bot.

As in the windows xp media player we can play/pause the song this what I want should be handled from the application.

hi, I have a sql in my program. What I want is exactly like this:
select *
from tbl t
where t.name like '%xyz%'
So in source code, I create sql like this:
CString name = "xyz";
::sprintf_s(szQuery, " select * from tbl t where t.name like '%%%s%%' ", name);
Here is szQuery when I execute
select *
from tbl t
where t.name like '%x%'
Just the first character is printed into szQuery.
What's wrong here? what should I do??
Thank you in advance.

Do you have UNICODE enabled ?
|
|
|
|
|
yes, Cedric. It's a Unicode project. In Project properties, The Character Set is "Use Unicode Character Set"
is that wrong?
|
|
|
|
|
Then you have to specify %S instead of %s. CString will return a wide-character string since UNICODE is enabled. If you look at the format specification[^] you can see that %S tells printf that the string is a wide-char string (when used with printf alike functions).

Thank you, Cedric.
I just change the Character Set property to "Use Multi-Byte Character Set" and it's ok now

I think your project is a unicode project. So the CString will be holding a pointer to unicode string. So you the following options.
1. use _stprintf_s() intead of sprintf_s( in this case szQuery also need to be TCHAR* or TCHAR[] ) or
2. Use CStringA instead of CString or
3. Convert CString content to multibyte characters using WideCharToMultiByte() API.
4. Undef _UNICODE.
