Have A Program Which Will Read Data From Comport When Ever There Is Data On Comport?
Dec 4, 2009I have a program which will read data from comport when ever there is data on comport. I am using Comport.DataReceived event to do that.My program will receive data very frequently and it is working fine. The problem is, it will work for 3 to 4 days fine but after that my receive data will slow down. I am receiving data with high delay (about 10-15 min).There will be continuous data to my comport.

VS 2008 - Sending Data To A Comport
Nov 2, 2010I am having trouble sending data to a comport..... I am a noob at this and have been doing my head in... I have done a fair bit to a few programs that I have on the go, but am stuck at sending some data to the comport...
I have in form1 put the serial port contol and added SerialPort1.Open() to that. I have then added 3 buttons that I was to use to send data to the port... Since this is for a radio scanner the buttons turn the backlight on / dim and off.....
LTN is used to turn the light on and works fine in hyperterminal.. I have got the port settings right in vs2008 but the code is wrong.
I have:

May 26, 2008how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.

Timer Tick Event And Serial Port / Read And Display Live Data?
Jun 21, 2009[code]...
I have a quick question regarding the serial port and timer tick event. Basically i have a micro processor connected to the PC via the serial port. With a baurd rate of 38400 set.When the PC sends the micro ":K + VBCRLF" the micro response with a string of information (ASCII encoded) and delimited with a "," and at the end of the transmission a cartridge return line feed is added.Example of sent string:
"12,1134,123,545,76,6868,34,232,1,2,3,6,7,8" These numbers are then split using the VB mystring.split(",") function into an array of strings, then the numbers are converted using ctype. After which my UI is then updated.I have Witten the code in a tick timer event using a timer count of 300ms. Although the program runs and the UI is updated i end it with lots of exception errors. I think allot of this is down to the serial port either timing out or not reading complete string.Or possibly the timer has not executed all the code before another tick event happens Even after adding a few try catch statements i am still having problems. Can anybody suggest a better way of doing it?I was thinking of using a do while loop and at the end a sleep function instead of the timer tick event.I need the speed as i am trying to read and display live data.

Display Data Linked By A Data Relation In Different Text Boxes?
Dec 7, 2010I have a data set with a parent child relationship between a patient table and an insurance table. There can be up to 4 insurances for each patient. I want to display them in 4 separate panels of a vb.net form. So if a patient had 2 insurances, then txtName1.text on panel 1 would have the company name of the first insurance, txtName2.text on panel 2 would hold the company name of the second insurance, and so on.
How do I display only the insurances related to the current patient? I've tried moving through the rows of the related table, but that gives me all the rows, not the ones I need. Everything I see on the internet suggest using a datagrid, but that's not an option in this case.
