Transperancy

[Guest]

I am having trouble understanding how to code to get a control to have a
transparent background in VB6

I have a .PNG file with the a pretty foreground image and a background as an
alpha channel. I am trying to use this either as a picture box or as a
label. I can set the background color nicely to any shade in the chart, but
transparent does not work.
I need to have the foreground 100% OPAQUE AND THE BACKGROUND 100%
transparent.
I can recolor the alpha channel to any color needed to specify transparent
with Photoshop.

I do not need to manipulate transparency during the execution, just need to
turn image visible or not and move it around.
I have found several Google references, but the code always results in "this
control not allowed transparency"

where do these lines of code go?

SetStyle(Control.SupportsTransparentBackColor, True)
Me.BackColor = Color.Transparent
Form1.TransparencyKey(System.Drawing.Color.Transparent)
The instructions are very vague.

suggestions??

Joisey,

Not the most simple question mostly. This is a VBNet newsgroup and your
question will probably have a very different solution in VB6.

I advice you to ask this question in the newsgroup.

microsoft.public.vb.general.discussion

I hope you find your answer soon

Joisey,

This are always very difficult questions to get answers.

Maybe can you search for your self in this newsgroup,
http://groups-beta.google.com/group...sparancy&qt_g=1&searchnow=Search+this+groupOr ask this in the newsgroupMicrosoft.public.dotnet.framework.drawing where you have probably the mostchange.Although png is a speciality from Herfried, so sending this message again inin this newsgroup with VBNet instead of VB6 can maybe help.Cor
