I'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.
[code] My project topic is on data conversion for length and weight. There is something wrong with the code.

Updating an Excel file from a dataset seems to work fine. But if I have text that's longer than 255 characters then I get the error above.I've been working on this for a couple of hours and I haven't gotten anywhere. I've tried messing with the connection string and changing a registry setting, but no luck.
View 2 RepliesI'm trying to fill a ListView control in a VB2005 project. It works fine from underpinning (Access) database IF all the data is present. However, if a field is blank (in this case - a field called "Actual Date" which is meant to be blank for this record), the ListView will stop populating at that point.I thought this may have been the 'CausesValidation' property of the ListView but that doesn't seem to change the behaviour.Is this an inherent feature of the ListView - if so it seems daft - or is there a property I need to change or an override that I need to code?

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 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.

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 3 RepliesLet's say you have a user class. When the user is logged in there are properties representing basic user info, an associated address and, say, 5 profile pictures, the last a generic lsit like this: Private _photos As List(Of Photo). However, instead of carrying the weight of the profile pictures in a session vairable, to reduce resource usage, I only want to populate them if the user needs to acces them. So, for the most part, the generic list of photo's is empty. Will it carry weight anyway? I'm trying to decide if I should just not populate ituntil needed, or if I should create an alternative "light" user class which doesn't have this property.

I have a VBA script that connects to a site.On that site, it puts in criteria to filter on a database. It then submits it.A pop up window appears asking to Open / Save / Cancel. I don't know how to interact with that window.It is possible to Save, and specify the download location without having to use Sendkeys?Note: There is no file to directly download. You have to run the report and it kicks back the file.I know this is VBA, but I think VB.NET has probably has the same result.
