    In my program, it prints the arry called buff, but it doesn't reconise the \n escape sequaence in my char array. Heres my program (AGAIN!), and can you please tell me whats wrong.

    I don't think that's gonna work. For each line you need to call the TextOut function:
    Code:
    if(StartDoc(pd.hDC,&di)>0 && StartPage(pd.hDC)>0)   //new doc...new page
    {
        TextOut(pd.hDC,100,100,"Line 1", 6);
        TextOut(pd.hDC,100,200,"Line 2", 6);
        TextOut(pd.hDC,100,300,"Line 3", 6);
        TextOut(pd.hDC,100,400,"Line 4", 6);
        TextOut(pd.hDC,100,500,"Line 5", 6);
        EndPage(pd.hDC);      //end of page
        EndDoc(pd.hDC);       //end of doc
    }
    Maybe there are other (more simple) solutions but I can't think of one.

    >>TextOut(pd.hDC,100,100,"Line 1", 6);

    [picky]
    TextOut(pd.hDC,100,100,"Line 1", lstrlen("Line 1")); // safer to use
    [/picky]

    FaceMaster,

    One thing you could try as it cuts down on code.

    When you have a lot of similar controls (like your edits for the days) it can be handy to use loops to deal with them. ie use a loop to clear them all.

    To do this I edit 'resource.h' . Find the edit contols (ie #define MON_ONE 1000) and put them in numerical order. Or use consecutive ID when creating them.

    #define MON_ONE 1001
    #define MON_TWO 1002 ect (or TUE_ONE ??)


    then in a header define a start for the loops and number of loops.
    #define FIRST_EDIT 1001//id of first edit MON_ONE
    #define NUM_EDIT 7 //number of loops / controls

    then you can
    Code:
    for(i=0;i<NUM_EDIT;i++)
    {
         SetDlgItemText(hWnd,(FIRST_EDIT+i),"Some Text");//the resource ID is an int cast, so substituting an int works
    }
    Now match an array of data's indexes to the edit's index and you have easy way to update you dialog.


    Code:
    char     sEditBuffers[NUM_EDIT][64];
    
    for(i=0;i<NUM_EDIT;i++)
    {
         SetDlgItemText(hWnd,(FIRST_EDIT+i),sEditBuffers[i]);
    }
    Something you could try.....

    Try using \r\n. I had this problem in VC6, but just \n works for me in .NET but so does \r\n so i just stick to that since thats what im used to.
