Only thing is that I can't get it to work :confused::confused: Can anyone else make it work, and if so ... what am I doing wrong?// call the method SetProgressBarText(progressBar1, null, ProgressBarTextLocation.Centered, Color.Black, SystemFonts.DefaultFont); // Set the ProgressBar Text method private void SetProgressBarText(System.Windows.Forms.ProgressBar Target, //The target progress bar string Text, //The text to show in the progress bar ProgressBarTextLocation Location, //Where the text is to be placed System.Drawing.Color TextColor, //The color the text is to be drawn in System.Drawing.Font TextFont //The font we use to draw the text ) { //Make sure we didn't get a null progress bar if (Target == null) throw new ArgumentException("Null Target"); //Now we can get to the real code //Check to see if we are to add in the percent if (string.IsNullOrEmpty(Text)) { //We are to add in the percent meaning we got a null or empty Text //We give text a string value representing the percent int percent = (int)(((double)(Target.Value - Target.Minimum) / (double)(Target.Maximum - Target.Minimum)) * 100); Text = percent.ToString() + "%"; } //Now we can add in the text //gr will be the graphics object we use to draw on Target using (Graphics gr = Target.CreateGraphics()) { gr.DrawString(Text, TextFont, //The font we will draw it it (TextFont) new SolidBrush(TextColor), //The brush we will use to draw it //Where we will draw it new PointF( // X location (Center or Left) Location == ProgressBarTextLocation.Left ? 5 : //Left side progressBar1.Width / 2 - (gr.MeasureStri -

The only programmers that are better C# programmers, are those who look like this -> :bob:
