• Visual Basic HardMarginX & HardMarginY Problems

  Hi, I'm trying to print to a HP DeskJet printer. Using PrintPreview the output is properly centered on the page, but when I print the page, the output is shifted down and to the right. After a lot of head-scratching, I determined that the printed image is shifted right by an amount equal to HardMarginX and shifted down by an amount equal to HardMarginY. I then subtracted HardMarginX from Margin.Left and HardMarginY from Margin.Top. With this adjustment the printed page is perfectly centered, but the PrintPreview is now shifted up and to the left. The values for the margins are: Margins=[Margins Left=50 Right=50 Top=100 Bottom=100] [Ha ...Show All

Anyway, you ...Show All

• Visual Basic How to get Stings of 8 bit Chars from Comm Port

  I am using an MSDN RS232 sample VB code in VSTS2005 to read and write from/to the Com1 port. But the example uses System.Text.ASCIIEncoding.GetString which only handles 7-bit ASCII characters, not 8-bit. I don't see any Encoding format that will return strings of simple 8 bit bytes of characters from the Serial port unmodified. What Encoding code can I use for simple strings of 8-bit bytes so that I can handle 8-bit binary data from the COM1 port properly How can I convert Byte Array into Strings of 8 bit characters Thanks for your Help. No, that's not quite what I need. I don't want to convert th ...Show All
