VS 2010 Auto-Save After Textbox Data Entered

Feb 13, 2011

Is there a way to save every time the user updates a textbox on the form? My reasoning for this is I don't want to lose all information typed into the form if they were to click on the "x" to close the form. I want the form to update whenever they type so if they forget to press a "save" button (or better yet not use a save button) the data won't be lost. I can use a textbox change event handler and code to update my dataset on every textbox in the form but it seems tedious.

VS 2010 Making A Loop To Check A Status Before Going On?

Dec 1, 2009

My next step is to allow a pause checking the status of the motor and or inputs before going to the next step. Reason is so it does not do many calls to the motor controller so fast. I need some help building a loop that checks status of the motor and if Motor1Active is 1 which means it is running that it needs to wait a bit and then rechecks itself. If it is not running it will continue to the next step command. Here is a sample of what I got but need to figure out say a 50ms wait before rechecking. I guess a loop that rechecks and waits 50ms and then rechecks the status and if done and reads 0 then it goes to the next step. if still 1 output data it waits 50ms and then rechecks. The following is what I got started with but need help with if then else and anything else statement.

' get the current status of both motors and the digital inputs
Private Sub GetMotorStatus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetMotorStatus.Click
Dim Motor1Active, Motor2Active, Motor1StepsLeft, Motor2StepsLeft, DigitalInputs As Integer

VS 2010 Program To Check The Number Of Items In A List Box?

Jul 6, 2010

I want the program to check the number of items in a list box, then send use that number to form a FOR loop and send each to the serial port individually. It actually sends everything, but the program always crashes after the last one saying that the sdprintcount variable is an invalid number for the index. I don't get it as this happens no matter how many items are in the list, and it always crashes on the last one. It sends it, but then it says the index number is invalid.

Dim sdmods As Integer
Dim sdmodsp As String
sdmods = sandwichmodlist.Items.Count

Save Multiple Times By Doing A LOOP Depending On The Number Of Checked Checkboxes On A Datagridview .NET 2010?

Oct 11, 2011

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

[Code]...

the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
