I am currently updating an application I wrote to view Car Insurance Policies, using a backed SQL database and a front end vb.net GUI. I now need to make a change.
I haev added a new table which has all Active Policies, and i have the old table with every policy there has been active or not. We do an import from a separate company, and there is no Active/Not Active field.
I need a query/code that will populate an "Active/NotActive" field in the old table. For example:

I'm a bit puzzled here. I did a form containing a simple datagridview containing data from an MDB file. The connection was alltogether done by Visual Studios wizard so alot of stuff was created automatically. Then I databinded the textboxes to each column in the database and managed to update the database via my own command buttons such as "Update" with this code:
Me.MainTableBindingSource.EndEdit()
e.MainTableTableAdapter.Update(Me.DBDataSet.MainTable)
Me.DBDataSet.MainTable.AcceptChanges()

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

I am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

I have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")
This process runs through analyzing, runs it in normal mode & prints the progress to the command window.
My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).
I can only access the external program thru the command line (its not my program) and I must do so from a form app.
I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.

With mp.StartInfo

I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.

I am struggling to pass a parameter to a VB.NET application via a Windows scheduled task. It works perfectly in Visual Studio (passing a command line arguement via project properties).If I am calling a VB6 application, then I will supply the following parameters and it works:
Run: c:progra~1TestTest.exe TestParameter Start In: c:progra~1Test However, if I supply the same parameters in VB.NET, the program throws an exception when it tries to create an instance of a class in the Form.Load: System.NullReferenceException cannot create instance of object.
I have also tried the following:Run: c:program filesTestTest.exe TestParameter Start In: "c:program filesTest" This time the status of the scheduled task changes to "cannot start".What is the correct way to specify command line parameters in a scheduled task for a VB.NET program?UPDATE I found the solution on this web page:[URL}.. I am still confused as to why the program would not create an instance of an object when I used the 8 bit paths (i.e. progra~1)
