I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway, my sample application seems to draw a text string at an image resolution of

In my Database application same of the operations can cause a bit of a delay, especially the ones that invoke more than one query on the DB.... In Windows (or was it in Java?) I have encountered this progress bar that doesn't gradually fill in but rather just shows this block of bars that moves from left to right in a loop...basically not showing exact info regarding the progress but simply showing that something is happening....Anybody knows what I'm talking about? And if so, if there is a way to implement this in VB? Kind of in a way that it appears when the function is called and starts looping until the function reaches its last lines and then disappears?
