Sep 27, 2009I tried to get the value text at the end of the field id equal text on the webpage at each line. I only want to get the two value text at each line which something is like this: 111.11.11.11:4000.

.net Printing With Both Texts And Images?
Dec 7, 2007I'm new to VB.net programming on printing a page to a thermal printer (Epson T88IV). I really had a hard time figuring out how to code the printing of a bitmap image and some text, while sending commands (through font control) to the printer.I tried sending the escape characters with Control font, but the Graphics.DrawString of PrintPageEventArgs do not allow it.. so I used the RawPrinterHelper class I found on Microsoft KB. It worked out but, I cannot print a bitmap image with it.Anybody knows how to do that?

View 1 RepliesLabel Texts And Image In The Picturebox ?
