VS 2008 - Panels And Their BackColor On Form
Jan 23, 2010
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.

I am trying to change to form backcolor from one colour to another with a time delay of 1 second. I have tried various things without success and this is the best I can come up with:[code]The problem I am getting is the colour is not changing until the loop has finished.

I'm trying to make custom ListBox with some graphics. Base is ItemCollection - each item contains Panel, 2x label and 2x picturebox. What each panel have to do:
- Change backcolor on MouseEnter and set color back when MouseLeave occurs.
- On MouseDown(LMB) - Panel stays "selected" - different color.
Problem: I can't access multiple panels at a time(and I need to), just one via sender as in function. Of course, I can do it hacky way, but I want to do it effective and regular. Is ItemCollection the right solution or should I do it just like an array of panels? Also I want them in one "box", ItemCollection is good for it.
Second "problem": I need to make labels "merged" in panels, when i MouseEnter them(labels), background color on that panel sets to my default color. when i MouseClick them(labels), nothing happens (need to "select" parent panel). It can be again fixed with hacky way, just disable labels - but then the colors of labels are unchangeable.

I would like to have two different panels (with associated buttons, textboxes, etc.) on the same location on a form. Is this possible and if so, how do I go about doing it? I need this to control two different boards with the same application.I realize it would be difficult to edit the form if they are on top of each other. Is there a way to place these panels apart while designing/coding, but have them located in the same spot on the form during runtime?

I am trying to conduct a research experiment using a psychological measure. Basically its a bunch of words and you need to specify a value for (1-5). So, what I did was take a numericupdwn box and a label and paired them up using a panel. I did the same thing for 19 other sets. I placed each one carefully on the grid, nice and neatly, however I need to randomize the order of how they are arranged.
I spent hours trying to figure out how to set the location point for a panel. But to use variables through a random number generator, is simply too difficult!

I am in the process of creating an all-in-one application for my own purposes. This application has panels with different "Mini-apps" inside of each. Timer, Notepad, Calculator, etc... The top of the application is a drop down menu and each of the drop downs has "Minimize" and "Maximize" for the appropriate application. When the minimize function for a "mini-app" is clicked, then that application is not visible. When maximize is clicked, the the application reappears.What I am attempting to accomplish is that when, for example, the two lower panels are minimized then the form resizes to only show the top two application.Basically, its like rows. If the two bottom are not visible, then the application should resize to fit nicer. An example of this type of application would be Windows Calculator (found in Windows 7 systems and probably other OS).[code]

When 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 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?

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 have a program that will use a lot of panels. The panels will all be on top of each other. Then if you clicked an option on one of the panels it would cause another panel to come up and so on. This is a game so it's not like the panels come up in a set order each time. Depending on what the use selects a different panel could come up in a different order.
z-order or hiding Z-order is supposedly a nicer way to do it instead of hiding so i was going to try that, but sometimes when a panel comes up it has info from another panel on it or the panel doesn't show at all and other things like that.Is there a way i could send all panels to back and bring only the panel i want to front other than doing something like..
VB.NET
Panel1.BringToFront()
Panel2.SendToBack()
Panel3.SendToBack()
[code]....
Since doing that every single time would take so much time depending on the number of panels there is.

I 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?

I'd like to set a panel to double buffered to prevent the massive flickering that I've got while I slide panels in and out of my form, but I'm not sure how to.I've Googled it, but all I've found is snippets of code which I don't know how to use. It involves something about creating your own class with double buffering enabled and then creating a panel from that class.

I 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?

I'm working on an menu program right now which has 20 panels used to display bmps that can be clicked on to select things. These panels are simply named something like pnl01, pnl02, etc. to pnl20. I'd like to make them into an array, like pnl(0) through pnl(19), so i can change the bmp on different panels like this:
x = 7
pnl(x).backgroundimage = image.fromfile(file)
i thought this had something to do with enumerated controls but after some searching i couldn't figure out if i was looking for the right thing.

I'm trying to make the BackColor of each row the same when a certain field is equal. When it reaches a row where this field is not equal to the previous one, it changes the BackColor property of the row.
Below is what I've come up with... but all the rows are remaining the same color. From what I can tell i'm changing the DefaultCellStyle.BackColor property and that applies to all cells, not just the current row in the loop. What property do I change to only affect the current row in the loop?
vb
Private Sub CommonSiteDGVBackColor()
Dim switchBackColor As Boolean = False
Dim prevSite As String = Nothing
