Custom Shape - Setting Transparent Color
Jun 28, 2010
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 want to create some custom shapes for MS Office which we can use in house.
For example I want to create a shape named "carton box" which have three - four default places where user can add some text. It is same as other shapes or I would say just like shapes (line, flowchart, arrow etc) in MS office 2007.
Is there any way to create and reuse such a new objects, also if user don't have these shape in their toolbox and get a document which includes these shapes; he should be able to see it (defiantly in read only).
Background - I am a .NET developer and also having small knowedge of MS office development in .NET.

I am looking to build some small custom buttons. I want to keep it simple and give them a gradient backgroud and use grey colours to illustrate shapes on them. Very similar to the buttons you see in Excel/Power Point/Word 2007 at the bottom right of the screen. The buttons are next to the slider bar which increaes the view % of the screen. These buttons are grouped together and have different combinations of squares/rectangles on them for viewing options Any idea where to start with the shapes?

I want to be able to create a custom shape that holds icons. Lets say for simplicity that it is a sqaure. I need the ability to load up to X amount of icons in the square. Lets say I need up to 6 icons. These icons will always be the same. However not all custom shapes will need them. I am assuming that I have to create a custom shape object class. I also want the icons to automatically adjust in size when I change the size of the shape. I am guessing that one way to do this would be to drop a TableLayoutPanel into the shape and then dock it to the shape. Then set the dock property of the icon to the cell that it resides into within the TableLayoutPanel in the shape. The number of rows/columns of the TableLayoutPanel would be predicated on the number of icons needed.

I am working on a contract to repair problems in a application that interfaces with a custom built digitizer tablet.The application recognizes the tablet at startup, initiates calibration to locate the pad limits and then saves those limits to file.During the run of the application the user has a cursor that is changed to a line with a X on the left hand side of it. The user then uses this custom cursor to click in a PDF document where they would like the contents of the Digitizer pad to be placed. When they click a box signifying the size of the digitizer pad along with the same blank and X appears. What I have been having issue with is that the box and the line with the X appear most of the time but on occasion the line and X appears at either the top or bottom of the box and the click is no longer at the line with the X but somewhere in the middle of the box. This really screws up things and often the user has to uninstall and re-install the application to get it righted.
The values that save the calibration points are bound to variables during the build process, there is a separate routine to calibrate the digitizer pad if the user desires to do it again.

I have a custom cursor for the user to allow them to position text in PDF files. For the most part there never seems to be a problem, but a choice few people are seeing massive problems with this.
One particular client loads the program, and then loads a PDF document into it. Once the program has loaded when the user clicks he either doesn't get a custom cursor or the signiture blank that is to show up is above the frame that is to surround the blank.
The user is using Windows XP on a laptop and the software re-renders the cursor and box every time. There is a signiture tablet that the user buys to connect to this software, and the user also has expressed problems with the Tablet not staying connected.
I can provide pictures of the changes and code if anyone would like to tackle this?

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.

I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

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.

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 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

I'm trying to create a simple transparent PANEL control. I want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.

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 have a semi-transparent custom control in vb2005 - works fine, except I can't get it to update/refresh correctly. If I update the custom parameter _backgroundColor, the control appears to be overpainted - e.g. each attempt to update the colour of the control overpaints the existing colour - until it becomes a solid block of colour. However, forcing a refresh of the form makes the control display the correct colour. Any ideas? I don't want to have to repaint the form just to get this control to render correctly. Code for the custom control is below.
