I have four forms only. The first one is the main menu, that contains three buttons, the first and second buttons go to form2 and form3;Button 3 should open a new form (4) and to write there just the total price.
In Form2: DataGrideView that contains a table made by MS Access 2007. That table contains only two columns and three rows. When you select the item, the price of that item should be saved to be added to the other selected items
In Form3: ComboBox that contains another table also made by Access2007. The same thing, the table contains two columns and the selected item has a price that should be summed with the first selection in Form2.
My Questions are:
1. What I did by adding data from MSAccess2007, is it right?First: View -> server explorer -> Browse(my database) -> Test Connection --> OK ...Second: Data Sources --> Add new database --> etc Third: I dragged one table and put it inside Form2, then the another table to Form3.Is that all right? <--- This is my first question.
2. Now, is, what I have done in step 1, enough to pick up the price of the selected item(s)?if not, what is the code that I have to write to make this connection, and where?
3. As I said, when I click on Button3 in Form1, Form4 should appear and give me the grand total. How I can write a code that makes this summation, and where?

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.
this is the

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.

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 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 been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate 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?

I have written a class library that creates a dll to pass data back and forth within the same compiled instance exe. Is it possble to configure this Class Library in order to pass the data produced in the first instance of an .exe to other instances exe programs written in VB.NET?
My first thought was to add a Module. Older versions used Declare Files. Is there something in the compiler that I should set where the variables point to a specific memory address, or something..., that makes the variable available to other VB programs running in a seperate instance?

I have vb 2008 and I have RSLinx classic, and a Allen Bradley PLC. I knwo there is a way to have vb call through linx to the PLC, I just don't know how. There are about 90 different tags in the PLC I would like to have logged into a csv/excel file. My thought on doing this was to have a very simple vb program to just collect that data and every day at midnight have it save it to a excel file. My problem comes when I try to talk to linx, I have no idea how to get them to communicate. I am just looking for some ideas on how to get that to work. I have tried link...whatever, and it seems that was for vb 6.

I am making a TimeCard application and I got stucked.. Anyway, the program looks like this: the user inserts date,start hour and finnish hour into 3 textboxes. On the fourth textbox it will show how many hours he has spent. I am using StreamWriter to save the data to a .txt file. My plan is to make this program as simple as possible (no database, access etc.). So, my biggest problem now is how to add all data from textbox4 (the amount of worked hours). I was thinking, to save into a separate txt file the data from textbox4 and then with StreamReader to get it back into a listbox.. but then.. how to add all of them? Im out of ideas..

I have a mdi container, that has several forms (childrens), one of those forms has only one datagridview, to show data, from an datatable...Image There're several image columns in the form.
To debug the process i created a new project only with one form and put everything working, and the images in the columns were just fine.
Then i "copied" the code to my application to the mdi children form, but the images doesn't show up.
After spending some hours trying to figure out what i was doing wrong i finally came to conclusion that the problem it's in the form/datagridview, that doesn't paint/refresh the images correctly if the form it's a mdi children...
There's something that i'm missing here? There's some event that prevent or override the images that i set? I need to put this to work, but i don't see how.
