looping through check boxes.. checkbox1, checkbox2, checkbox3...... Error in the code ocheck = "CheckBox" & Str(t) as "Run time errors may occur when converting 'string' to 'Microsoft.office.interop.word.checkbox'." Dim No_Checkboxes As Integer, ocheck As CheckBox
[Code]...
On a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?
I've got a page with a ton of checkBoxes on it. I would like to have a loop that can can just go through all of them but I can't get it to work. I know similar code works for a desktop application but apparently not for an ASP page. [Code]

Where am i going wrong?? i do not get any error...but this code is not working for me.
I'm trying to loop through a bunch of checkboxes I have created on my aspx page. I would like to get all the values, and parse them to a string to send to another page as post variables. This is what i have so far:
aspx page:
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox0" runat="server" /> Name</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox1" runat="server" /> Training Year</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox2" runat="server" /> Continuity Clinic</div>
etc...
aspx.vb file:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Submit.Click
Dim targetURL As String
targetURL = "report.aspx?"
' This is the part i can't figure out.
' For Each checkbox on page
'if checkbox is checked
'targetURL &= checkboxid & "=true&"
End Sub
My goal is to build another page that will then check these values using Querystring variable, and build a listview out of them. (a report page, that basically lets the user select checkboxes of the columns they want to see on the report).

I have been using the following code for quite some time to list the property values of an object:
Dim instance As New Configuration
Dim propValue As Object
For Each pi As System.Reflection.PropertyInfo In instance.GetType.GetProperties()

Works great but we've gotten alot of properties at this point and could use them in alphabetical order.
I would like to know how to loop with textboxs. For example. I would set the text to "Hello" And the loop will send this...
-"Hello1"
-"Hello2"
-"Hello3"
I have tried many looping techniques but they all used listboxs and even modifying them I could not get it to work correctly.
I thought I could use this, to loop through all checkboxes in a frame:
For Each cb As CheckBox In Me.frameSearch.Controls
cb.enabled = False
Next
But it walks through once, then it comes with error:
Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.CheckBox'.
There are indeed labels within 'frameSearch', but I thought that the "For Each cb as Checkbox" would loop only through all checkboxes..? Following does work, but it seems a bit of waste of CPU time, since it will loop through all controls!
For Each cb As Control In Me.frameSearch.Controls
If TypeOf (cb) Is CheckBox Then
cb.Enabled = False
End If
Next
How to do this more effectively?
I have to set a drop-down list with multi-select checkboxes. It seems to be a combination of combobox and list capacities (at least as I know them in VB6), so what's the best controller for these purposes in VS2008?
View 1 RepliesI'm working on a school project and need some help getting pointed in the right direction. The project is a lawn care application with 2 forms in which the user can select different services they want for their lawn. On Form1 I have 3 checkboxes the user can select: mowCheckBox , fertilizeCheckBox , and mulchCheckbox each with a different price. And nextButton to navigate user to Form2
On Form2 I have a listbox which shows the services the user selected, a totalLabel which will show the total dollar amount of the services, and a calcButton to calculate the total dollar amount.
The problem that I am having is being able to get the total dollar amount. If the user selects the mowCheckBox ($25) and the fertilizeCheckBox ($20) in Form1 I need the totalLabel in Form2 to show the total but cant figure out how to??

Each part of the order has a group box, with the type of sandwich, side, beverage, dessert you want selected via a combobox, and toppings selected with checkboxes (the code for the beverages is coded differently and giving me 0 problems, but at the instruction of the teacher who saw beverages giving conflicts with the way everything else was coded because radio buttons are used instead of checks).

I have this Visual Basic class I'm taking online. At this point in the section all I'm supposed to know about are Do, Do While, Do Until, Exit Do, Continue Do, and For Next loops. So try not to go off in a fancy super-coder direction. And everything is (preferably) made through Console Applications on VBE 2008
Problem 1:
Write a program that evaluates the factorials of the integers from 1 to 10 using an appropriate data type. (factorials are... factorial of 1 is 1, factorial of 5 is 120, or 1*2*3*4*5=120)
Problem 2:
Make a diamond - 1 asterisk at the top, 9 asterisks at it's widest - using only nested For...Next statements to print the asterisks AND spaces, minimizing use of output statements.

[Code]...
Have this Uni question; which after 20 minutes of frustration I'm sending it to the brain trust (you might be interested).Write a program that, when a button is pressed, checks the contents of a textbox. If the textbox does not contain a number, the program informs the user of this and does nothing more. Once a number has been entered, the program will do something trivial such as displaying double the number in a message box.Notice that this can be done without explicit looping,even though the user might repeatedly enter non-numbers. Because it is an event-driven program, each iteration is started when the user clicks the button. The looping is driven by the user, not by a looping statement.

Dim iWidth As Integer = picCapture.Width

As you can see, I have 2 sources. Would it be possible to not show the preview window, but instead loop through all the sources?
That would be in a timer, so like each 10 seconds a pictures is made from each source.
i have a winform and i have about 30 labels and 30 picture boxes on it. What i would like to do is fill each label and picturebox with a value and image from a backend database. I could have easily done this in vb6 using control struture , for eg.
for x = 1 to 30
picturebox(x).image = value from database
label(x).caption = value from database
