Question

So I am trying to draw a string in a loop in the PrintPage event of a PrintDocument:

for (int c = 0; c < currentwords; c++)
{
    // index is a global int that starts at 0 and f9 is a font with size 9
    ev.Graphics.DrawString(allitems[index], f9, Brushes.Black, new Point(100, 100));
    // I used new Point(100, 100) for debugging purposes but normally I would
    // do some calculating to see where it is to be printed
    index++;
}

It seems all normal, and the debugger shows that it gets run when I use a breakpoint but when I display the document in a PrintPreviewDialog it does not show up. allitems[index] does contain a value and I am not sure why it is not displaying. I am printing other strings and rectangles outside the loop and they show up in the dialog. If anyone could help me please post here, Thanks!

Edit:

Here are the graphics modes/rendering hints:

ev.Graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;
ev.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
ev.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
ev.Graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
ev.Graphics.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality;

Edit 2:

Alright, so I used:

ev.Graphics.DrawString(allitems[0], f9, Brushes.Black, new Point(100, 100));
for (int c = 0; c < currentwords; c++)
{
    // index is a global int that starts at 0 and f9 is a font with size 9
    ev.Graphics.DrawString(allitems[index], f9, Brushes.Black, new Point(100, 100));
    // I used new Point(100, 100) for debugging purposes but normally I would
    // do some calculating to see where it is to be printed
    index++;
}

And only the DrawString outside the loop was being displayed but the loop should work and the code is being run.

Answer 1

So I found that the problem was if I am drawing more than once in a for loop like so:

for (int c = 0; c < currentwords; c++)
{
    ev.Graphics.DrawString(allitems[index], f9, Brushes.Black, 100, 100);
    ev.Graphics.DrawString(allqty[index], f9, Brushes.Black, new Point(200, 200);
    ev.Graphics.DrawString((allprices[index].Contains('$')) ? allprices[index] : "$" + allprices[index], f9, Brushes.Black, 300, 300);
}

It would not show any of them at all. To fix this I have to have each DrawString method in a different loop, not sure why it doesn’t work other-wise.
