Transparent Controls Over Form With Background Image Shows Backcolor Not Image?

Sep 18, 2009

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible.  I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet.  Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left.  I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image.  I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

Png Image Transparent With Video In Background?

Mar 26, 2011

Me again. I also have a png image and a web cam video in my form. I have transparent parts on the png image that show through to the form background colour.

How do I set it so it shows the video in the background, when I put the png image over the top of the video?

At the moment its still shows straight through to the back of the form?

Forms :: Transparent Background Over A Picturebox?

Jan 3, 2009

I have a picturebox with a pic in it, and I have a label on top of the picture.

I want the background of the the label to be transparent, so I set it's background prop to transparent and it's parent to the picturebox. I do this on form load, but for some reason the label entirely disappears once the form loads?

Transparent Listveiw Or Stretch Listview Background Image?

Apr 15, 2010

I am making an operating system based game in visual basic. The real problem is that the game runs full screen and when it comes to desktop backgrounds I am having heaps of problems.First I had the desktop as just the forms background image but I needed to add icons to the desktop so I anchered a listveiw onto the background and the problem is that the listview is not transparent and you can't see the desktop background.

I thought that I could fix that problem by setting the background image on the listveiw as the background image but the problem is when i set a background image on the listveiw there is no option to stetch the image. The only option is to tile the background image.

How can I get the listveiw either transparent or set it a stretched background. ( the user gets to choose a desktop background so they all need to be able to stretch to the full desktop of the user's screen resolution.)

Forms :: Transparent Form Background Not Crisp?

Jul 28, 2009

I have an app that uses transparency so that the background of the app is a custom shape. The problem I am having is the rounded corners are jagged. Not a nice clean rounded corner like you would see on an icon or widget. I have tried several different image types (i.e. PNG, GIF, etc). But it seems when I use the transparency Key the quality on the edges gets worse.

Programmatically Determine Background Of Image (logos, Etc) And Make Transparent?

May 20, 2011

I'm attempting to write a solution so that my user's can "watermark" their Images with their Company Logo. I've got the actual watermarking part done and working so now I'm creating the "upload logo" feature so that they can provide me with the Logo they wish to appear watermarked onto their Images.I'm using VB.NET and this will probably end up in a Web Service that accepts the Logo JPG file, and returns the "altered" Logo. What I need to happen in this Web Service is:

1) Gray-scale the image. Which I have working as well, thanks to this article.

2) Make the background transparent (so the logo looks clean when watermarked onto an image). This is where I'm stuck.

I think for the most part, any logos that are uploaded will have a generic white background but I can't assume that. Is there a way to somehow detect the background of an image or the background colors, so that I may make those colors transparent?So basically what I need is just a way to determine the background on an Image or even just the background colors so that I may make them transparent.

Non-linear Performance In Scaled Background Images?

Aug 5, 2011

I have a form that scales a background image. The form is painted 30 times a second (using Invalidate so it redraws the whole background image). When the window size is less than half my screen (1366x768), Task Manager reports that the program's CPU usage is 00. If I increase this a few pixels in width, all of a sudden the CPU usage jumps up to 50+. I can get up to about 606000 pixels in the client rectangle before it starts exhibiting this behavior

Set Custom Background Image?

Dec 4, 2009

I'm having a few problems creating a transparent form. The reason I want to do this is because I'm attempting to make a custom border (one that isn't exactly square).I can already get the form to be transparent, then I set my custom background image, which all works perfect, it even detects when the mouse enters the image, which is great. (I use transparency key to make the form transparent)

The problem is, if I add ANY control, or even if I just save the file, NOTHING else, the whole thing has a spaz attack.. Instead of having the image with the transparent form, the square form appears every time I run the app.

Image Transparency Along With Transparent Forms

Oct 29, 2009

i know how to make a picturebox have a transparent image within it, and i know how to make forms transparent, but what i cant seem to figure out is how to add an image which has transparent parts to a completely transparent form and have it still look nice. you know when you find images which look really good by them selves, but then look really bad when moved to a different background cause they still have the white border (or any other colour border). is there ANY way which i can accomplish removing this border? its almost like the alpha channel that removes the ugly border, when putting the image on the form, is forgotten about and the colour of the forms background fills in the gap..

The customer wants a gradient which I will need to repeat, but how would I create this? the image is 1px in width 976 in height [Code].

Interface And Graphics :: Button Background Gradient Disappears?

This is VB 2008, under Vista. I can't seem to change the background color of a button without the gradient disappearing.Strangely enough, you can even set the background color to itself and the gradient disappears. How do you keep the gradient but change the color?

Here's an example:

Button1.BackColor = Button1.BackColor ' This should do nothing!

Transparent Control's Background

Dec 16, 2010

I have been looking in a lot web site and forums trying to find the way to make my picturebox background transparent or catch whatever I drew on top of a transparent panel, let's explain it.
Case 1-) I trying to make an app, where the user can load onto the winform a word document(I have part this ready), then I put on top of the control where the doc. is loaded a transparent panel(this part is ready too) and the user can sing (on top the panel) then I need to get the user's draw(sing) and print it in the document.

Every time that I try to do it always I get everything that is within the panel area, then I just want the user's sing.

case 2-) I tried to use a picturebox then it works perfect, I can get just the user's sing and print it back in the document, but the problem is, I can't put a picturebox on top of the control where the doc. is loaded because then I can't see the doc.

If anybody wants to see the code to make the panel transparent, or catch whatever you draw on top the pictureBox.
