VS 2008 Get The Data From A Ship To A Data Centre Which Is Located In A City?
Aug 10, 2011
We have to get the data from a Ship to a Data centre which is located in a city. And the Ship has broad band connection via Satellite . So for capturing data from the ship we suggested to create a WCF services which will be deployed in Ship. And the Application Running on the Data center will call the service and get the data and upload it to the data centre . The same type of Application will be deployed in the data center to upload the data to the ship.

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.

I am new to VB. I have created some labels/textboxes in my Form1. I use them to do some calculations. Basically, this is my calculation area (in Form1) and then I want some of the results that have been calculated and showed in these texboxes to be shown in labels which are in another form (Form2). So here is what I have done in terms of coding:
Label12.Text = Transactions.ComboBox1.SelectedItem
Label13.Text = Transactions.ComboBox2.SelectedItem
Label14.Text = Transactions.ComboBox3.SelectedItem
Label15.Text = Transactions.TextBox1.Text
Label16.Text = Transactions.TextBox2.Text
These codes are in Form2 and Labels 12-16 are in my form2 as well. My form1 is called Transactions as you can see. Everything looks OK, when i run no errors, also when do the calculations and I go from form1(Transactions) to form2, labels 12-16 show the results from form1 but the problem when I go back to form1 and change the values and go back to form2, the labels 12-16 are not changed. They simply show the old values regarding of the fact that they have been changed in form1. So how can I make form2 to show them correctly, to refresh the form or what?

I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

I typed this question once already, hit preview, and somehow never got the preview and lost what I typed. It has been that kind of a day.So here is my quick overview then I am going shopping. I am using OLE DB to select from an excel spreadsheet. It has over 15000 rows and 33 columns. Sometimes even when a cell is not null, it is returning a null value. If I just do a "select * where [termination date] is not null", for example, it will return no rows even though I can see with my own eyes that sometimes termination date is not null.

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];

I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.
There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?
If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.
Here are my code to read data from the socket, I have taken away some irrelevant code:
Sub test(ByVal ip As String, ByVal port As Integer)
' this sub is meant to run forever

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)

I need a DLL to be available to my app at runtime but the app has to be standalone with no installer so I can't package the DLL and ship with the app.I am using the technique discussed in this thread: url..That works perfectly. My problem is that I need to do the same thing with an additional DLL and I can't figure out how to do it. It would be easy enough to create a "stream2" and a "raw2" but how do I return both of them from the function? Or how do I only return the one that is needed at the time?

For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

A gyrocompass simulator? Basically i work with stabalized VSAT antennas that track a satellite around 30,000 K in the sky from a ship getting tossed around at sea. These antennas need to know where they're pointing so they can find the satellite, this is where the gyrocompass comes in. It tell the antenna how many degrees from north it is pointing.
I need a simulator to imitate the output of a gyrocompass on a ship that is moving around. The program would pass data out of the serial port so i could hook it up to the antenna and it would know where it is pointing when i am testing it.

I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?
