Accept Weight Data From Detecto AS-350D?
Oct 27, 2010I'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.

View 1 RepliesGet The Topics With Certain Topic Codes?
Apr 9, 2010I have a dataset that pulls information about topics. However, I need to filter the information so i only get the topics with certain Topic Codes (These topic codes are in the form of an array).
Me.TblTopicsTableAdapter.Fill(Me.MainDataSet.tblTopics)Right, let me try and explain better.
I have an array named COURSE_Topics. This array contains topic codes as string elements.Currently, my table adapter query looks like this:
SELECT [Topic Code], TopicName, NoOfCourses, Duration, StartDate, EndDate, [Level] FROM tblTopics
At the end of that query i need to add a WHERE [Topic Code] = - then list of topic codes in the array.

View 1 RepliesControversial Topic Of Winsck And TCP / IP Connecting
Sep 22, 2009I have read - recently - many topics concerning the connection of TCP/IP connecting versus using the old winsck connecting method. Currently, I'm in the middle of a project and I'm completely lost as to which direction to go because I've tried both directions (winsck & TCP/IP) without any sort of avail.

VS 2005 - TableLayoutPanel - Does Using It Add Weight In Application
Aug 8, 2009Does 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 Replies.net - Get Length Of Data Sent Over Network To TCPlistener/networkstream?
Jan 8, 2010It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far:
'Must listen on correct port- must be same as port client wants to connect on.
Const portNumber As Integer = 9999
Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber)
[Code]...
I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception.
The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.
Storing Data With Unknown Length In Array
Jan 15, 2010I have a piece of code written in Visual Basic:
Dim n As Double, i As Integer
n = 4
Dim Ramp_length(1 To 4) As Double
For i = 1 To n
Ramp_length(i) = Cells(13 + i, 5)
'Cells(65 + i, 7) = Ramp_length(i)'
Next i
Is there a way I can reproduce the result without declaring the array with a "fixed" length? I eventually want the code to read off a column of data with unknown length and store it in an array of equal or smaller length so it can be altered.
VS 2008 - Read Data Offset & Length
Mar 18, 2009I have a string:
0E0100000000000000000003CB7352
I need to be able to look at Offset 14 and Length is 1B. I need to be able to look at bit 0 - bit 5. I have NO idea how to read data like this so I wish I could be more specific but I can't. Can someone tell me how to read the specific bits and translate them? I have no idea how to google this. So if someone wants to point me to a search pattern. That would be awesome too.
Here is a chart that describes the bits:
bit 0 : Light LED (head) status, 0: OFF, 1: ON
bit 1 : IR-Radar power status. 0: OFF, 1: ON
bit 2 : IR-Radar detector status: 0: fine, 1: barrier detected.
bit 3-5: Charger staus
0x00 : nothing happen
0x01 : charging completed.
0x02 : in charging
0x04 : something wrong, error occur.
bit 6,7: undefined, do not use.
Open A Specific Topic In A Compiled HTML File?
Apr 8, 2009I use DocTools to Create a Compiled HTML Help File. I want to link to a specific topic in the help file from my program, but the filenames of the html files are generated randomly.
Is there any way to open a CHM to a specific topic by name?
I created a wrapper for DocTools, so I could have the command line piped to a text box and then I could obtain the Topics from there and save them in an INI file that I read when I call the help, but I don't know how to pipe the command line to a textbox.
