I got a code online to read via rs232 using serial port ,the code uses readExisting() to get the data(im geting data form a MettlerToledo scale connected at com3,9600,8,N,1)problem now is that i change it to ReadLine() but it captures the weight once and i need the weight updated all the time!

ok the scale is a truck scale connected to a terminal (cougar 8530) that was connected before via Rs232 now the pcs doesn't have a serial port so someone attach a usb adapter to it the thing is i cant capture any data from it. im an developing a small program that can capture the weight of the truck (trucks are weight with the product and then re-weight with out it so they can find how much the product or products weight) so any ideas? suggestions?
View 1 Repliesi would put this here maybe someone would be in the know.Waiting to here back from the company also.At work we have a truck scale and it has a control that reads the weight.Model of the control is Toledo Scales Model 8530. The control has a serial cable to communicate with.I am trying to figure out what command to send to it to get the weight back.I have connected to it with a serial monitor and i dont seem to be getting any information back so thought maybe I had to send something to it.Right now we have a 3rd party dos program that is communicating with it that i dont have the source to.
I dont know if i could just bypass the control and connect to that serial cable or not,,, i would need to find an adapter if so.Ok probably shot in dark but thought what the heck this is a smart group
i am developing an application which needs to connect to a weighjng scale throug rs 232 and capture the output. after inserting the record however the pc needs to send the tare command to the weighing scale in order to set the scale to zero. now he tare character as far as i guess ia T i sent the command like this
serialport1.write(chr(27) & "T" & chr(13) & chr(10))

How can we calculate ideal weight for a given height in vb 2005. If weight is given in Kg and height is given in inches..

View 3 RepliesI am trying to make a program that converts the weight of objects on earth into other planets. i have trouble with naming things like weight ratio and planet because VB program doesn't accept the coding. i don't know where to put theh data in the disk so that the program can access it when it runs.
Imports System.IO
Public Class weightcalc
Private planet structure

Does using it puts any degradation in the performance of an application like the loading of the form/usercontrol is slower since the TableLayoutPanel has to be instantiated and the controls has to be added to it? I use it extensively and from time to time I combine it with a Panel also so I would like to be enlightened if there is no cause of concern in using it.
View 3 RepliesI've found a scale, Detecto AS-350D [URL].. that hooks up to a computer. I was hoping someone could help me figure out how to get the information (weight) from it. I've looked around but can't seem to find any information on it. I've never wrote a program where I accepted data from a device likes this so kind of confused where to look.
Update: I'm coding in VB, and the device connects to the computer via serial port.
I have a Repeater... And it has a Weight field. the weight it displayed in a textbox. I have this piece of code:
lblTotalWeightCalc.Text += NewDV.Item(i)("Weight")
This will get the Weight and display it in my label. But when I select more than one item (which will have two weights) it will show: For Example:
Item #1 : Weight = 20
Item #2: Weight= 50
The total Weight= 2050 (it doesn't add them together) I need them to be added together....
I'm using Visual basic 2010.net with service pack 4.0. I'm using the built in chart control to generate a line graph. I have a series plotted on the fastline graph. Is there a way of accessing the weight/thickness/boldness of the line and changing it? I was able ton change the colour and I could even change the point size on the fastpoint graph.
Code:
Private Sub DisplayGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

So I am trying to write a program and I don't even know where to begin. I am trying to make a program where you enter the persons weight then pick (from radio buttons) "convert Pounds to kilograms" or "convert kilograms to pounds" and then it should convert the weight when you click display weight button to display the converted weight value. Any ideas?

View 5 RepliesSo I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

In VB.net 3.5 SP1 I have a Windows Form with three DataGridView controls. One DGV takes up the whole bottom half of the form. The other two share the top half and are side-by-side.
I'd like to have each DataGridView scale appropriately. More specifically I'd like to have column widths and row heights adjust to the size of the form. Then I'd like the cell font to auto-fill based on a change in the cell size.
I've used the Dock property for the controls to scale to the size of the form. How can I get the rows and fonts to utilize the increased form size?
On the Y-Axis of a bar graph, how can I display descriptions as the scales instead of numbers? I don't see anywhere that I can do that.

I need to draw a world map. I got necessary coordinates.I can draw it on a picturebox. To zoom in/out, I multiply the coordinates by a scale and draw them on the picturebox. At the same time I change the size of the picturebox according to scale.Now my problem is, it seems that the picturebox has limitations in size. I can't make it bigger than 32767.

Things do goes bad, as it flicking all the way. I using a indicator from AD series which read data from load cell of a truck weight bridge.
