Check Checkboxes Status And Write Checkbox Label Using A For Next Loop?
Mar 7, 2012
I have several checkboxes in a groupbox on a vb 2008 express userform. I would like to check the checked status of each when clicking a command button and then write the checkboxes caption to be used in an email or print out. I've tried several methods and always end up with the same error "Invalid Cast Exception". I have read the help on msdn and still do not understand how to make it work. Here is the code I've been trying
Dim chk As CheckBox
Dim sb As New System.Text.StringBuilder
Dim names As String
For Each chk In gbInterior.Controls
[code]....
I have also tried the code below but cannot figure out how to check the status and print the checkbox caption.
Dim ctl As Control
For Each ctl In gbInterior.Controls
If TypeOf ctl Is CheckBox Then
I have 5 checkboxes in total.I want to check how many checkboxes have been checked.I dont want to write checkbox1.checkstate,checkbox2.checkstate and so on...How do I accomplish this effectively?
I have 11 asp.net checkboxes in my asp.net webusercontrol .. i want when checkbox1 is check thenrest of all checkboxes will be checked and if checkbox is uncheck then rest of all checkboxes will be unchecked how to do it if all my checkboxes are inside webusercontrol panel1.
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
I have a input form that has a number of check boxes on which relate the users enquiring courses. I need to create a loop of some sort that allows each checkbox to be checked it is selected. If so, output that within a message box. Thats it put simply anyway.

[code] I want to check checkbox and change color on one label and enter date on another.Then I want to uncheck the checkbox, restore the color on one label and clear the other..This works perfectly but only after the initial check. On the first check the correspsonding labels are handled properly but all the other labels are changed also, ie. the color changes on one set and the other set cleared.I can see the problem is in the Else If statements but can't understand why if the coding iswrong it works ok after the first check.

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.
I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.
I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked.
I'm trying to use checkboxes to show and close child forms.I'm using MDI. I want to try and make the child form show inside of the parent form like it should.This is the code I was using:
[code]...
And that works, but if I close the window instead of using the check box and then try to use the checkbox to open the new window again i get an error:Object reference not set to an instance of an object.Also I have more than one checkbox (each one serves a child form) and I would like to be able to open and close any of the child forms at any time.
I use the following code to create a Label in the status strip when a child window is open.Public Sub StatusStripPanelAdd(ByVal lCount As Integer, ByVal sImage As System.Drawing.Image, ByRef sText As String, ByVal sender As Object, ByVal e As System.EventArgs)
