[VB6] - Hide textbox(or other control) backcolor

[joaquim]

can i hide the textbox(or picturebox) backcolor?
(it's a question that normaly i found the code for a form)

May be by setting the control's transparency key to the color, but I believe it only works on forms. Problem is that Windows doesn't use the Alpha component of colors when drawing...
It can be done if you add the picturebox to a form, with as backcolor an unused color (like pink) and give the form a transparency key of that color. Then you make sure this form stays on top of your main form (as if it is a control) by handling the position/sizechanged events of the main form.

The best solution is a custom control, but for a textbox this can take a while.

If you want multiple controls to have this, simply make one top-layer form which contains the controls (and see-through spots) with a background form having the background to display. (like an image of some sort)

No API is involved here though.

You can try to search for it. Here is one for example:

Though this is not a truly transparent picturebox, but it may be something to play with.
