GetUserName fails on WinXP/MinGW [message #19684]

My code

void MyDlg::MyDlg () {
   username.SetData(GetUserName());
   // username is defined as LineEdit in lay
}

Gives an error:

C:/usr/include/winbase.h:1580: error: too few arguments to function `BOOL GetUserNameA(CHAR*, DWORD*)'

I am using U++ 2008.1 Windows installation without MinGW.

And anyway, should not it be GetUserNameW()?

Hard to say without the rest of code. First wild guess is

Upp::GetUserName()

Well, maybe it should, but we are still struggling to support Win98...

Most of code is capable of using 'W' variants where being run on WinNT (or better), essentially hiding all encoding details.

(Anyway, we plan to reconsider the whole issue this year. Maybe 10 years of supporting the crappy OS is enough....)

Now I'm getting a different error:

 error: `GetUserNameA' is not a member of `Upp'

BTW, where is this function defined in U++? Which header/source? I can not find it.

I think it can be dropped now. I'm unable to run my UPP apps on win98 using current SVN version.
See this: Win98 crashes

Ah, that might explain a thing Smile

Do you have LATEST svn version? I think this was contributed after last major release.

Well, as I said in the very first message: "I am using U++ 2008.1 Windows installation without MinGW."
