Click transparency - VB.net

[Bittenfleax]

I made a thread on StackOverflow, however the majority of people on there are dicks.

So, I am making an "overlay" of a sort. 

 

Long story short I need an image on top of everything (which I got). But I am trying to get it so it presses behind the image and does not focus the vb.net application. I can do it with only one color however (the white background color) with a transparency key so everything white is transparent. (however my image is not).

 

I tried to create a graphic but had no luck. Has anyone else been able to do this? - Thanks

I could do it if I wasn't at school -.-

if you want to do it yourself download paint.net and paste your picture in, then get the magic wand and change the tolerance until it only detects the white, delete it then save it

BAM your good to go

Yeah, but the bits that are not white I need so I can see them, but I can click straight through them.

 

Thanks for the reply

Your question should include the GUI framework you're working with.

 

If you're using WPF then it's easy. Control the transparency with the Opacity property. To click through the control set IsHitTestVisible to False.

 

If you're using WinForms, it's more difficult (consider switching to WPF). See here for clicking through a control. Unfortunately I'm not sure how to get full transparency on your image.
