VS 2008 Checkboxes Not Showing Correct State?
Nov 5, 2009
I have a form that has many checkboxes located on a tab control with 3 tabs each tab has checkboxes on it.I have a button that when pressed selects all the checkboxes. That does work and it does execute all that were selected. However there are no checkmarks appearing at all. This worked before! It seems like the more checkboxes I added to the form the less they properly showed f they were checked or unchecked. Now none of them show unless I close the form and reopen it then all of the boxes are checked like they should be when the select all button is pressed.

I can create a checkbox array as follows
Code:
For n = 0 To 13
With (chkboxarray(n))
.Tag = n + 1 ' Tag of button
.Width = 35 ' Width of button
[code]....
But when I run the program the checkboxes only display 2 states (they do work as 3 states). what I am missing to display the "Indeterminate" state?

This is in VB6 (may also apply to VB.net) CheckBoxes can have three states (Checked, Unchecked, Greyed).
But I'm using them to set boolean variables (MuteSound, etc.) This is definitely a value that has only two states. Unfortunately, the Checked and Unchecked don't correspond to a True/False value.
So, I can't have:

Using .Net, I need to generate a response based on only the checkboxes on my form that have had there states changed. So how do I know if the check box has changed from its previous value before submission. I can't use the onchange event because the user may check multiple boxes before submitting.

I am using VB Stuido 2008, Net Framework 3.5.I have one Checkbox to Identify the record as Inactive if checked. When I load the form the checkbox is alway unchecked, which is what i want. However, when I go to add a new record the checkbox, not the text for the checkbox is always shaded green, not a checkmark. The checkbox then reacts as if it is checked. This makes it necessary to uncheck the checkbox or else all my record react as if checked.
in the table defintions I have set the default binding value to ((o)) which = unchecked. Iafter setting the default value to ((0)) I deleted the checkbox from my form and then replaced. Not I still get the checkbox shaded which reacts as if Checked.

just ran into an odd problum with treeview node text I add a top node and I wanted it's text in bold. The bold works fine but half the text is missing
Here an example
vbnet
Dim sFont As New Font("Verdana", 8, FontStyle.Bold)
Tv1.Nodes.Add("TOP", "0123456789", 0, 0)
The code above for me only shows 012345678 and not showing the 9 any ideas if I use regular style it works fine only happens when I apply the bold style.

I have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.

In my program, I can place an order for glasses.To do this, I have 4 text boxes:
StockNumber: [12345]
GlassOrPlastic: [Glass/Plastic]
ScratchCoating: [Yes/No]
UVFilter: [Yes/No]
Currently, it works fine... BUT I need to type in Glass or Plastic, I need to type Yes/No and same for each thing, wondering would checkboxes be more effecient or how would I do it?How do I even use checkboxes to get the same values...(If I type in Glass it adds �30 to the price, if I type in Plastic only �15 is added...)So if a Yes answer = �20 and a No = �10 How can I do that with checkboxes or whatever...My code for when I click the order button, myAddNew just adds my information in..
Private Sub OrderButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OrderButton.Click
Dim myValue As Integer ' Base value of frames
Dim myValue1 As Integer ' Glass or plastic value

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?

I'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??

This may sound like a silly question, but I can't seem to find an answer.Is there any way to "Check" a ListViewItem when the user selects it via property? I'm sure I can figure out how to do it in code, but I thought there was a property of the ListView. I looked through the documentation, Google, and in the properties panel, but I can't seem to figure it out

This is a simple program, nothing crazy, just for a VB class. The program just a food ordering form. 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).

Ok everyone knows that you can get the visibility of a control by control.visible...now my question is this: how can i get the visibility of a control without taking parent controls into account ...ie. if i have a button in a picture box ... and the picture box is invisible (even though the button property is visible in the designer) the value returns false.How can i return the visible value for the control that is displayed as it would be in the designer?

I've got a nice little setup at the moment with how my button is, but for some reason, it shows a black border around it if I show any MessageBox or Dialog that I have, and I can paint over it, but it's impossible for me to do so without it looking wrong.[code]If I click the exit button without the message box code, it works fine!

i have a toolstripsplitbutton, and i want the drop down items to showhide when you click the button not just when the mini arrow is clicked so i call toolstripsplitbutton.ShowDrowDown on the event toolstripsplitbutton.click and to hide, i can call toolstripsplitbutton.HideDropDown but i can't seem to find any property that would indicate whether the toolstripsplitbutton is currently dropped down or hidden..i did not expect this to be this hard but i can't seem to find any indicator of whether or not the list is dropped down.
