How do I clear/reset the BackColor of a windows application form? For instance, I have a set of radio buttons, each one changes the color of the background form color, when i reset the radio buttons i would also like to reset the color of the form back to it's original state?

I got on my form textboxes, checboxes but also a groupbox which holds texboxes.
The idea is to be able to clear and reset all of these by clicking a reset button.
At the moment i got this
Private Sub ClearFields()
Dim ctrl As Control
[Code].....
But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.
Is there an easy way to reset or clear a DataReader so it can be read through more than one time? I found a Close method but not an open method.
View 1 RepliesI currently have a chart that plots lines of a changing value every time it is called via a timer.
Everything is running as I expected and I am happy, but now I want to be able to press a [STOP] button which will stop the timer and stop the graph from updating, (which I have coded and is now working OK), BUT I then want the code under this [STOP] button to clear everything from the graph, so when I re-start the timer, the graph is cleared and starts plotting fresh points on a clean graph.
The problem I currently have is that when I press the [STOP] button and then press the [START] button, the new lines that get plotted are "added" to the existing lines that are already on the chart, instead of having a new "blank" chart, with no data on it.
So what I am really asking is does anyone know if it is possible to reset a chart clearing everything off it so it is ready to start displaying fresh data?
I was hoping it was something like: "Chart1.Clear" or something simple like that, but I can't seem to find anything that will do it.
I have built up an interface in VB2008 with many textboxs and labels on. When I click "New", I would like to clear all the textboxs and labels, i.e. each with a NULL value. Meanwhile, I also would like to clear all the arrays behind the program, i.e. the arrays which are not shown on the interface but is important for the calculation.The only way I could find out now is to clear the textboxs, labels and arrays one by one. So if there are 100 textboxs, 100 arrays, I have to write 200 lines in total. Obviously, it is not expected. Is there any other quick ways to directly reset everything to the beginning when the interface is just opened?

So im makeing class, where i need to change BackColor for part of form..What i meen is, i need to change forms BackColor, but not for all form, but for, example 20px from top..
View 5 RepliesWhen I change the BackColor for a Form, and then add new buttons, they have by default the same BackColor as the Form itself. That does not show on my Windows 7 development computer, but when I use the program on an XP machine, all buttons appear the same color as the form.
I correct this by changing the button's BackColor property to ButtonFace, but it is a pain to do it all the time and some times it gets past me and a wrong color button goes into the application.
Is there a way to change how this works so all buttons are placed with ButtonFace BackColor by default?
How can I change a form's backcolor to gradient one. The code (VB.Net) -
e.Graphics.FillRectangle(New Drawing.Drawing2D.LinearGradientBrush(New PointF(Me.Width, 0),
New PointF(Me.Width, Me.Height), Color.FromArgb(0, 58, 140),
Color.FromArgb(0, 215, 255)), New RectangleF(0, 0, Me.Width, Me.Height))
'fade from left to right
This code changes the form's background to a gradient one. It works fine. Now I want this to take place in an MDI form which will be a container for other forms. If I turn option IsContainer = False then it works but otherwise it does now. How can I change backcolor of MDI Form to a gradient one ?
How do i set the backcolor of the form to a rgb color via script, im making a theme tab, which changes the color, but i want the default color, and i have a custom color that is really close to it, but I dont know how to set to an rgb sadly. or i could use an alternitive by setting the background to the system color control, but I also dont know how to do that.This is what i have so far:

I've created a Form with 1600 Panels. Which are all called Panel (1-1600).
E.g. Panel1, Panel2, Panel500, Panel1000, Panel1600
I want a code so that if you click one of the Panels, the BackColor of the panel you clicked on, turns from Control to Red
I think there is an easier code than just adding this:
Private Sub Panel1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.Click
If Panel1.BackColor = "Control" Then
Panel1.BackColor = "Red"
Else
Panel1.BackColor = "Control"
End If
End Sub
To every single panel.
How to reset the properties of the form as well as all of the control properties values when i click a button.

View 4 RepliesI can make the background color of the form transparent by using: "Me.TransparencyKey = Me.BackColor"
"Me.BackColor" is set to default "Control", which I think uses 240;240;240 as the color.But using that color as the transparent mask color leaves gaps in controls who are also using that color.By changing the Me.BackColor to a "rare" color this problem is fixed.What problem really is, is that using the "Control" color I get the ability to ALSO interact with whatever is behind my form, which any other custom color does NOT.
Question: Why is this?
Request: I would like to use a custom color as the transparent color but KEEP the ability to interact with whatever is behind the form, how can I make it do that?
I am in thinking about building a small app. Its indended to be a screen grabber with a difference.The window form is see through by setting the Transparancy and BG properties to equivalant values. The TopMost property of the form is set to true.The concept is that the form is placed over the area of the screen that you would like to capture. As the form is see-through you can adjust the form around the area you would like to capture.Once you have done that, its just a matter of click a toolbar button eigther save it to file or copy to the clipbaord and placed in an image array.
Tipicaly it should have some of the functioning of a digital camera which at your lesure allows to view images seperatly in the array and deside wether to keep them or delete them.What would be the best control to use as the capture control? ie. The form itself or an Picturebox that is also seethrough?If the image carn't be crabbed that way, then it should be possible to read the coordinates of the PictureBox (top,left,width and heigh) relative to the underlying image on the underlying app. Than once the coordinates are known it should be possible to copy that rectangle of the screen?
My program is only one form, at a certain point I want the form to reload, and have all the variables and arrays be reset? I am able to to reload the form by:
Dim frm As Form
frm = New frmMain
frm.Show()
But the original form still stays open? My program is a version of blackjack. when who won or lost is figured out i want all the cards to clear (held in an array of picture boxes) I have random numbers generated (also put into an array) each random number then finds the image of the card it belongs too and then places it into the array of picture boxes. How to reset the arrays so I thought maybe trying to just reload the form would work?
Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

View 1 RepliesI created 3 Forms (Form1, Form2 and Form3) and I added a button on every form. This is code for Button1 on Form1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.BackColor = Color.Red
Form3.BackColor = Color.Red
Me.Hide()
Form2.Show()
End Sub
Code for Button1 on Form2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form3.Show()
End Sub
Code for Button1 on Form3:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form2.Show()
End Sub
Now, the problem is that when I click on Button1 on Form3 it shows Form2 but the Form2 BackColor is not red, it is default color, A.K.A Control Color. But I specified in Button1 on Form1 that Form2.BackColor is Red. And also if I click on Button1 on Form2 when Form3 shows it, the Form3 BackColor is also default, it is not red.
I know one way to solve it but it is so not-professional. It is that you add on Button1 on Form2 this:
Form3.BackColor = Color.Red
and on Button1 on Form3 this:
Form2.BackColor = Color.Red
It is ok in this situation but what if I have more stuff, for example if I have an option for changing theme so it has to change all labels and buttons ForeColor, what then, is there any other way?
