Method not working

[Chuck Bowling]

VS 2003, .NET 1.1

I'm throughly puzzled here. I can't seem to get the method below to work...

private void AutoSizeHeight( )

{

Graphics g = this.CreateGrap hics();

int x, lineCount;

SizeF layoutSize = new SizeF(this.Widt h, this.Height * 100); // oversized
height

this.Height = (int)Math.Ceili ng(g.MeasureStr ing(base.Text, this.Font,
layoutSize, new StringFormat(), out x, out lineCount).Heig ht);

g.Dispose();

// this.Height = 400; // this works

// this.Height *= 9; // this works

this.Height *= lineCount; // this doesn't work

}

//---------[end]---------------------

This method is part of an inherited TextBox control. It's purpose is to
resize the height of the control according to the height of the contents. It
works fine if I assign a constant value to height or multiply by a constant.
But when I try to multiply by lineCount it doesn't change. Height and
lineCount definately both have values but for some reason they won't
multiply.

I'm I doing something wrong or is there something strange going on?

Note: I don't know what it means, but the lineCount is red in the Watch
window...

Re: Method not working

I am confused. In your text, you say that 'lineCount' definitely has a
value, yet the code you posted: this variable is not assigned.

What gives?

Re: Method not working

If I understand correctly, the 'out' keyword in the MeasureString method
should assign a value to lineCount.
