.net - Can Disabling A Control Cause A Radio Buttons Value To Change
Sep 22, 2010
I have a For Each loop going through the controls in a panel disabling them. When the loop reaches one certain grid control and disables it the CheckedChanged event fires for the next control in the loop which is a radio button.
The call stack is as follows:
System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnCheckedChanged(System.EventArgs e = {System.EventArgs}) + 0x15 bytes
System.Windows.Forms.dll!System.Windows.Forms.RadioButton.WnProc(Microsoft.AGL.Forms.WM wm = WM_RADIOBUTTON_NOTIFYVALUECHANGED, int wParam = 0, int lParam = 0) + 0x17 bytes
[Code]....
I don't understand how control.Enabled = False can cause the OnCheckedChanged event.
So I am trying to make a program that consists of a form with 3 radio buttons and a picture box. I want my default background color for the picture box to be yello and I do not want any of my radio buttons to be selected. However, when I start debugging my program, one of my radiobuttons (red) is already selected and the picturebox is red.
So I tried adding the if statement..but it kept stating "expression expected"; and it had ByVal highlighted in blue, as you can see.
I am trying to create a simple paint program with radio buttons to change colors and size of the brush and draw within a panel on my form(VB 2008 Express).I cannot get the buttons to work. What do I need to put in the radion button event to change brush color and then also brush size? Following is the code I have so far, with nothing in the radio button events, because everything I try does not work.
Public Class PaintForm
Private shouldPaint As Boolean = False ' determines whether to paint

i am having a problem with a calculator that i am making. i am using radio buttons as selectors for the operations (+-*/). i have two input-boxes. i want to do some error checking. for example if the user want to find the mod of a number, i want them to only use inputbox1 to enter the value. [Code] the problem is that when other radio buttons are clicked the effect doesn't change. how can i fix it so that other radio buttons don't have the same action. i am using visual studios 2008 professional.
I have some experience with VB6 and it was easy to do a control array for radio buttons such that btnSMP(0) and btnSMP(1) and btnSMP(2) were together and if user clicked on btnSMP(1) it was shown with the blck dot on it as selected. If one then changed mind (which seems to be a very common thing) then if user clicked on btnSMP(0) then it was selected and the other one was not.That is not possible in Visual Studio 2008 for what ever reason the higher ups decided. I have read a number of articles now in MSDN about how to duplicate that feature in VB.net code but it seems to be a lot of work and they add in many features I do not have a need of

I have placed a few radio buttons in a panel, but I have a weird problem where they require 2 clicks to change their state.If one of the radio buttons is checked, and I click once on another radio button, this will uncheck the checked radio button leaving no radio buttons checked. I then need to click the radio button a second time to change its state to checked.

im trying to add two radio buttons together to get a full price, they are split up by two group boxes. Meals and dormitories, I have the prices on how much they are, but I dont know how to put the right radio buttons in the right places and then add them up, here is the code I have so far

I have a need to add 16 radio buttons to a groupbox but I want to be able to select 2 radiobuttons per groupbox. (2 vertical columns of 8 radio buttons each) The radiobuttons are created dynamically and each set of eight have different names to distinguish them. Do I really have to create 2 groupboxes and put each set of 8 in each groupbox and put those groupboxes into my parent groupbox? Is that it with radio buttons...if they are all in 1 groupbox then there is no way to select more than one at once?
I'm having issues with my current homework. I've got 6 different radio buttons and depending on which one is checked, the corresponding price shows up in the text box. I'm not sure if I need to create a sub-procedure or what. I can't seem to get anything to work.

I've gotten this far with the code but not sure where to go next.
I've figured out how to run through the radio buttons and save their checked status to a text file. Now Im trying to recheck them according to the value. Here is what I have.[code]...

I have several textboxes in my form and a groubbox that have four radiobuttons. I want all the values of the textboxes (and the selection of the radiobuttons) to be stored in sql server. As far as the values of the textboxes in concerned, I managed to do it. But what about the selection of the radiobuttons??? This is the code I am using for the textboxes:
objConnection.Open() objDataAdapter.InsertCommand = New SqlCommand() objDataAdapter.InsertCommand.Connection = objConnection
What I have is a search program where people can enter in a person's policy number or first and last name and then chose which company to choose from. I have 7 radio buttons. Two are grouped in one groupbox the remaining 5 are grouped in a second groupbox. The two in the first groupbox are to chose whether to search by policy number or by firstname and last name. There are three text boxs. In the other group box is just radio buttons with list of companies to choose from with one radio button set to search through all companies. My problem is, how do I get my code to where I can choose to search by either policy number or by first name/last name and to then choose which company the person is with. Here is my code I have so far:
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim connetionString As String
Just finished this and figured I would share.. It just uses images, but works very well.. Have a couple work arounds in there so you can still bind it to a Class. Let me know what you think:
I'm not sure about the last line re. data from a radio button. Does this say add to the structure only if the male radio button is checked?
My second question is how do I get data from the gender variable in the structure? I want to calculate how many Males versus Females have been stored in the array. I've tried all sorts of things, but nothing works.
Examples of faulty code / logic are below:
Private Sub btnAddtoStructure_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddtoStructure.Click
Dim i As Integer
