Does Not Support Transparent BK Color
Jan 14, 2009
One last hangup with an application and I've tried like heck to research this but no luck.When I do a button click on my open file, it brings up a sub with all the open file code same for my save file and everything works perfectly.If, the open file dialog is on the screen and you should click either cancel or close I get the following argument exception unhandled, (and I've pasted all the details).It throws the exception at the very first line where textbox1 gets it's backcolor(txc(0)) is the variable in my.settings
If I open ANY file I have saved by clicking OK, all goes perfectly, it loads the file and I don't get the exception.I only get it when I click off the open file dialog with cancel or X.

From my understanding PictureBox's don't support transparent backgrounds. What I am trying to do is just have a single picture that needs a transparent background just to be on display with my form. So how do I do this?

I am trying to use a background image for one of my programs and I get this error when I try to make the BackColor Transparent. It allows me to use the Background image I want but I get this error when I try to change the BackColor to Transparent. A Box pops up that says "Property value is not valid.", then when I click Details, it says "Control does not support transparent background colors."

I don't know what is wrong here. Firstly It is Winforms application using .net 2.0.
I have a Panel (backcolor set to Transparent, I want it to be see-through).
At run-time I want to overlap this panel on controls, show a new panel over it (as to make it feel like a model dialog). but the panel is not rendered transparent.

I am developing a small windows application(vb.net) in vs2005.I will have a grid view that will keep on refreshing for every 5 seconds.For that grid, I want to set a background image which I can do.But my problem is, while refreshing the grid image also get refreshed which make the form unpleasant to view. So, I try to make the grid backcolor as transparent so that I can utilize the form background image which will solve my problem. But I got the error message that, we can not set the grid back color to transparent. Is there any way to achieve this.

I have been using custom shapes for some time now but the pixels always have to be 100% solid or it mixes with the color I have set as transparent and its starting to get a bit annoying. Is there any way possible that I could take a png image with transparent pixels and use that as my custom shape without the transparent pixels becoming that color I chose? This is what I have: I want to put my image as the background without the purple being where the transparent pixels are.
Me.Backcolor = Color.Purple
Me.Transparencykey = Color.Purple

I started off with a VERY simple form and added a picturebox item to it. The code I was following used a procedure in the Form1.vb to override the transparent color of the image:
bmp.MakeTransparent(Color.Fuchsia)
bmp was defined in the Form's "Load" section.
Now things are different. I have more than 20 picturebox items now, each created in the Form1.Designer.vb code as follows:
Me.Tile020.Image = CType(resources.GetObject("Tile020.Image"), System.Drawing.Image)
Me.Tile020.Location = New System.Drawing.Point(922, 297)
Me.Tile020.Name = "Tile020"
Me.Tile020.Size = New System.Drawing.Size(64, 64)
Me.Tile020.TabIndex = 3
Me.Tile020.TabStop = False
The image is referenced from the resources. When I run the program, I'd like all these images to have their backgrounds transparent. None of these controls is currently referenced anywhere in the code at present. What's the best way to get them to display transparently, other than recreating them as transparent .PNG's?

I have tried this:
For i = 255 To 1 Step -1
MyPanel.BackColor = Color.FromArgb(i,Color.Red)
Next
This will make the background color fade to transparent.The problem is, I don't want only the background color to change.I want to change the visibility / opacity of all the controls inside that panel too..

Is it possible to change the back color of a form to transparent? I don't want to use transparent key. Because I want to put a semitransparent picture in a picture box and there is a big problem with transparent key. The semitransparent pixels show the transparent key color.

I've tried adding a splash screen ]...to one of my applications and after exploring a while I somehow managed to get it working what bugs me now is that my splash screen is in fact a image inside a picture box and the form always shows the control color behind so what I tried is adding the form color to the transparency key this worked, somehow now, I use a png image that has some transparent effect also what I've noticed is that where I would want to show the transparent effect from the image the transparent color that is set in the forum shows below is the image to get my point of view:
I'm wondering if I can remove that "pink" color (set by me in the forum) from the image .I want to get a effect like the one Adobe products have for example

after many weeks of annoying compatibility with windows xp, I realized that I should change the .netbar buttons to standard windows buttons. When I did this, and put the button on the transparency area and then debugged the application. I found out that the transparency add-in made the text inside the button transparent: How can I make the text show just the color, not transparent?

I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)

I want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?

I have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.
