Code for blinking label in visual basic


follow this

http://www.pcmag.com/article2/0,2817,1951108,00.asp
Is the line executed? Did you start the Timer (calling start method or
setting enabled=true)? Do you execute other code while you expect the Timer
to tick? If you do, the Timer won't tick before the code has finished it's job. To solve it, execute the other code in another thread. This prevents the main thread that also keeps the Timer ticking, from being blocked by the other code.

Create desktop icon


Check: http://www.altiris.com/upload/wise901.htm

Basically you need to create a link to your program.

The link should be created into the following directory:

(System Drive):\Documents and Settings\All Users\Desktop

You can do this in any language, C, VBasic, Pascal, even a DOS batch file.

1) Retrieve the installation path of your program + the name
of the executable.

2) Call the windows API to create a shortcut.

3) Here is a link to a solution in Delphi Pascal, which is my
favorite development tool:

http://www.delphifaq.com/faq/delphi/windows_file_system/
f410.shtml

4) Once you get the Delphi program to program to work,
you can simply call it from Wise, at the end of the
installation ...

or

you can call Wise from the Delphi program before creating
the link.

Hope this gets you started, unfortunately it is a little technical.

Martin.

LM90 ( LOGIC MAster ) communication with 90-30 series


Try "COMx 9600,E,8,1"
LM90 is a DOS package. I assume you are using DOS 6.xx to use program. Windows will not allow DOS program to access com ports. Use a VB, C++, etc to access PLC. Be very creative in programming... convert ladder instruction to HEX with checksums.

Good Luck.
