    WM_GETTEXT error

    I'm trying to populate a char array with the text in a text box. Here's my code:

    Code:
    //in my global variable declares:
    HWND Txt1;
    
    //in my message handler, case WM_CREATE:
    Txt1=CreateWindowEx(0,"Edit","Text Box",WS_CHILD | WS_VISIBLE, 15,90,90,15,hwnd,NULL,hInstMain,NULL);
    
    //the offending code, called when a cmd btn is pushed:
    int iMaxChar=100;
    char buffTxt1[100];
    SendMessage(Txt1,WM_GETTEXT,iMaxChar,&buffTxt1);
    Error C2664: 'SendMessageA' : cannot convert parameter 4 from 'char *(*)[100]' to 'long'

    I've tried:
    Code:
    SendMessage(Txt1,WM_GETTEXT,iMaxChar,buffTxt1);
    I'm sure I'm missing something simple I just don't see it. Thanks in advance for any help.

    Code:
    SendMessage(Txt1, WM_GETTEXT, (WPARAM)iMaxChar, (LPARAM)buffTxt1);
    Quidquid latine dictum sit, altum sonatur.
    Whatever is said in Latin sounds profound.

    Thanks, Uraldor. I noticed the (WPARAM)/(LPARAM) in the MSDN library and didn't even think to try it!

    Like I said, I had a feeling I was missing something simple.
