Reading Data From Weighing Scale
Nov 14, 2010
I have a digital weighing scale I need to connect to the PC using RS232 communication port. Every time I weigh an object, automatically the result/ weight will display in the the texbox control in Visual Basic Application.I use to receive data via a timer for continuous looping sequence output to a textbox. 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. It there's any way to stop this flicking without effecting the continuous loop?

What I have managed to do is currently display a chart with 3 bars on it linked to textboxes what have numerical values in them when the form is loaded. i.e TextBox1 has an initial value set in it's properties of 10, TextBox2 has a value of 20, TextBox3 has a value of 30.
When I run the program the graph displays these values correctly.
I have also got a button, Button1 which when pressed will plot the chart again, (so if I manually change the values in the TextBoxes after the form has loaded), it will display the new values via the bars.
The problem I have is that if if once the initial values have been plotted when the form loads, i.e. 10, 20 & 30, the Y axis of the chart has a maximum value of 35, so that all the initial values for the bars are shown. But if I change the values to say 15, 30, 80. and then press Button1 to update that bars to thier new values, the bars change but the one that show's 80 can not been seen fully as it goes off the chart, as the Y axis still only shows a maximum value of 35!
Does anyone know how to get the chart to resize to be able to display all the bar values within the chart each time the values are changed and the Button1 is pressed, whether it be reducing the graph for smaller values or enlarging the chart for higher values?
I am not 100% sure I am going about it in the correct way as I have not got any experience in using charts and am having to stuble about the net trying to find basic example code of how to setup and use a chart
My code so far is:
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

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?

Data binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?

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?

Is there a way to scale a report to fit in the printable area? Like Adobe Reader. My reports are in A4 size, but they're to close too the page borders. I bought a new printer, and the printable area is smaller than the old one, and there are some cuts in the report.I didn't change the paper size or whatever, just the printer.

I am on a project helping to analyze the load a VB.Net WinForms application can take. This app has been in production for several years and has many many products on it. We plan to add more products but see the client footprint rapidly increasing. This is contributing the degradation of performance on the system overall.There is duscussion that moving the UI intensive portions of the app to ASP.Net it will reduce the client footprint and solve many of our issues.My question which of the following will scale better in terms of performance and load? ASP.Net(VB) Web based architecture VB.NEt WinForms 3-tier architecture

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.

my final year project title is monitoring weight changes in digital scale / indicator.i bought one digital scale online from A&D in order to test out my system.however unlikely other device (GSM MODEM, RFID...) there are no drivers or libraries (DLL) from this device.. with only the digital scale and (rs232 9-pins to usb convertor i bought) i was like lost wondering how to get communicate with the device.i have been search around in the internet for similar post.. but there are most likely dealing with the data receiving already. is there any journals or manuals for references? i willing to study over this and not simply ask for full codings.
- how to communicate with the device (serial port communication)
- is there any driver / libraries need to install bfore everything?
OS using - windows 7 ultimate (laptop)model of device - A&D JM-SERIES 150lb

i 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 toying with a project where I can position objects runtime on the screen. I also have an small "preview"-window, where I want to see the outline of the objects.I have an object array who have size and location on the "scene". Now I want to loop through my scene-objects and create one picturebox in the preview-window for each object in the "scene".
So, I have the size of the "Scene" and an array of the objects that are visible on the scene. Every object have an size and location mapped to the scene.I also have a preview window that have an dynamic size. How do I create a preview that scales down to the preview window? To make it easy, I loop through the scene objects in the scene and create a picturebox on the preview-form for each object, that uses the preview-forms size to do the scaling.

I have a VB.Net application with a datagridview consisting of several columns. I would like to be able to increase/decrease the cell font size when the user resizes the cell so that the value fills the cell. I do not see a property that would do this and wonder if there is one or if there is some algorithm by which the appropriate font size can be calculated based on character count and cell width.

Im craeating a dart scoring program (to use myself in my dart room) and want the user to be able to click in different areas of a picture of a dart board to register the thrown darts.
This program will be resizable, so the picture of the dart board can change it's size when the user change the program window size.
Im using a list of polygons(pointF-arrays) to map up each area and run some calculation to see if the mouse click is inside the polygons area, but how do I scale those polygons correctly when the picturebox is resized? My polygons are hard coded to map the dartboards area of the picture at a specific size.[code]...

I use zedgraph to draw figures in my vb.net project. The x axis of figure is date. I have two text boxes showing the minimum and maximum values of x axis in date. The following code shows how to get x axis values when a figure is zoomed by using isEnableWheelZoom property, also see this link zedgraph EnableWheelZoom, how to get axis values after zooming?. But I found that I only get axis value, e.g. 4508.345, but NOT the date that I want. Actually on figure, it shows date correctly. My question is how to get the minimum and maximum date on figure?
Friend WithEvents gcMain As ZedGraph.ZedGraphControl
Me.gcMain.IsZoomOnMouseCenter = True
Me.gcMain.IsEnableWheelZoom = True

I have some combo boxes that basically set labels and scale multiplication factors for an XY grid. The combo boxes themselves work as they should. Two adjust scale levels of the XY grid (label and multiplication factors) the other changes the Y axis units (Imperial/Metric). The issue comes when I try to replot old data... I have the data in the array and have confirmed it is accurate...but...
When I apply the appropriate value to combobox.selectedindex and then call the Sub that actually makes the scale changes, the selected index reverts to -1. Small Example.... (note consider all variables as public and all routines in a single class - ignore spelling - this is a quick subset recreation not a copy).
Private Sub ReloadGraph()
combobox1.selectedindex = LengthScale(GraphNumber)
Call LengthLabels()
PlotUnits = Units(GraphNumber)
Call UnitsSet()
[Code] .....
OK - so I did add some code..... I did not actually run this code, but this is essentially a snapshot of what fails....when I step through line by line, the selectedindex changes to -1 as soon as I step to the second line of the second 2 Subs BEFORE it processes the second line (i.e. always after I step off Private Sub xxx() ). Again, both UnitSet and LengthLabels work OK separately when called, it is ONLY when I set the selectedindex from a variable (and again, it DOES set OK) and then call these routines that the selectedindex goes to -1. I have read a bunch of stuff relating to selectedindex and selectedvalue resetting IF one or the other is blank, but I have tried setting both in testing and this fails too!!
