• McGeeky Vista problem with handshaking on serial ports?

  I am working on an application for a device that uses hardware handshaking on the serial port.

• Andrew Grammenos How do I detect compile mode in VB.net useing VS.net 2003?

  Hello, I am trying to detect the mode in which a vb app is compiled (ie: Release or Debug) so that I can take certain actions based on that mode. For example: I am trying to pop-up message boxes as I go through my code to let me know where I am, and what the current state of things inside the program is. Obviously, I wouldn't want to do this in a release build. I'm primarily a C/C++ programmer and would do it using #define and #ifdef if I were in C. Is there a similar construct for VB Thank you for your time, Chris Betancourt Sometimes the answers are found by poking around. For more information please visit here .

• Jboul Write/Read data: comma seperated file

  I need to create a comma separated file as output for numerical data and I also would like to read numerical data from a comma separated text file as input. Data output should write out data of type double, string and integer and separate them with a comma into a human-readable text file. It should also be possible to start a new line in the output file.
