View 17 RepliesReading Decimal Value Of An Extended Ascii Character?
Sep 1, 2011I'm Alan and I'm writing a little program (beginner), but I'm stuck and I can't get any further. So I hope one of you guys can help me solve following problem.Let me explain what I'm making, so it can give you all a better perspective.
For a this project I'm receiving data via the RS232 communication port. So basically I receive bytes. These bytes are converted to a string. So for example I receive this:"BAA" this is good because I can get the correct decimal value for "B"(66) and "A"(65) using the command asc("A") in .NET.but sometimes I receive a character that exceeds the 0-127 limit for example ""(128) (please see [URL]..But now when I try to get the decimal value of "" I get 63 instead of 128. I searched the Internet and forums for an answer but I didn't find one that fits my problem.
So if it's possible, can one of you code experts explain me how to fix this problem ? It would help me a lot. I hope I described my problem clearly, but if there are some questions,

Read A Decimal Value Via Maskedtextbox (or Textbox)?
Jan 22, 2011In COBOL, I read a value (a currency amount with 2 decimal places, for example) via a picture clause (and a screen section, of course), like:
WORKING-STORAGE SECTION.
01
VALUE-TO-READ PIC ZZZ,ZZ9.99.
...
[Code]....
The tricky part here is, whenever the decimal sign key is pressed, the input procedure understands that the following number is to be displayed to the right of the decimal point (not left).
Now, I'm trying to do this in VB. Unfortunately, my all attempts failed with MaskedTextBox.
Do I have to hardcode this procedure in my program, or is there an easier way to get around this?

View 6 Replies.net - Computer.FileSystem.DeleteDirectory() With Read Only Files?
Sep 23, 2010I recently came across a problem with My.Computer.FileSystem.DeleteDirectory(). It will not delete read only files.I found out by Googling that I could delete the read only files by changing the file attributes to 'Normal'. So I wrote a recursive function, as below.
Private Sub DeleteDir(ByVal dir As DirectoryInfo)
For Each d In dir.GetDirectories
DeleteDir(d)[code].....
It seems to work fine, but it would be nice if My.Computer.FileSystem.DeleteDirectory() had another parameter to delete read only files, or there was an easier way to do this.
