Change Colour Of Picturebox By Selecting Different Radio Buttons?
Oct 9, 2011
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.

To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _
[CODE]...
To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.

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.

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 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.

the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:

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.

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

I've created a structure as seen below:
Structure MemberType
Dim FirstName As String
[CODE]...
This was at the very top of my code. The gender data comes from radio buttons.
My code for adding user input into the structure is:
MemberArray(i).FirstName = txtFirstName.Text
MemberArray(i).Surname = txtSurname.Text
MemberArray(i).Gender = radFemale.Checked = False
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
[CODE]...
I was trying to get a running total based on totalmales (and the same for totalfemales) and then display these results in another form.

I even tried to put in the Form_Load area,

I'm trying to draw multiple radio buttons on my form. I've used this same logic to draw multiple text boxes and for some reason, this doesn't work.
For counter As Integer = 0 To rc - 1
'controller name Radio button and properties.
Dim dynRadio As New RadioButton()
Me.Controls.Add(dynRadio)
[code]....
I have validated that:
rc = 3 and the loop does iterate three times.The values that come back from the db are correct.xAxis and yAxis are placed properly and is the same increment as my text boxes.It's just not giving me three radio buttons for some reason. It only displays the first one.
