Transparent forms! HELLLLLPPPPP!!!

[bruta]

Grrrrrrrr!!!!!

For some reason I can't make my form become transparent!

I am in the middle of creating an MP3 player and want a realistic style! I want to have a trasparent FORM!!

Is there some way I can do this because, quite honestly, VB5 help is pretty crap.

whoa, thanks abdul !

Ive been fiddling around with all kinds of API functions to get my whole form transperent. Couldent ever get it quite right.

IT WORKS NOW :D

Normally, if you put a GIF with a transparent background in an image (not a picbox) control the background will be transparent on the form- You can see other controls through it. But if you do this on a form using your code, the once transparent GIF has a grey box around it.

Do you know of a way to keep the GIF's background transparent when you make the form itself transparent? Is there a way at all?

[abdul]

Sorry, I still did not get it:

Do you want to put this gif(let us assume a circle) directly onto the form or Do you want to load the gif in a image box and then you want to show the image box on the transparent form?

So basically, Do you want to, somehow, show the circle(gif) on the transparent form?

[kedaman]

if you convert your gif file into ico format, it's automatically blitted transparently if you put it in a imagebox. If you want you could also use regions to your advantage, I made a control once that cuts out the regions specified by a userdefined color you use as mask. If you want I could upload it here.

[abdul]

What do you want to make the region of? If it is an image control then its is impossible. But if you just want to show a transparent picture then you can put that in a picture box, and then make the regions of picture box(you also need to make the form transparent and set its borderstyle to none)

[DaoK]

abdul he ONLY want to put a background (exemple a picture of the letter "B" and he want all the background transparent but not the letter "B". But he want the inside of the "B" transparent (the "B" letter is saved in transparent Gif so he should be able to see inside the "B")

I hope that gonna help you to understand him.

[Andreas@ALSoft]

I'm not sure but it should be possible to create a user control with a maskpicture and a background picture so that the regions around the background picture are transparent.
Set the control's controlcontainer property to true
Then place that control on your form you made transparent with abdul's code.
I hope it works...
