This is very nice but more complicated example. I'm looking for simple way , to exchange image control with png supportable control.

The reason AlphaImage Control is complicated is that it supports 32-bit alpha images(Png, Bmp, Ico), Gif and will work on OS Win98 or later even if you do not have GDI+ installed.

If all you want is Png support, this can be done easily with GDI+ which limits you to XP or later(unless you install GDI+ on Win98). You will need at minimum a PropertyPage, UserControl, and a GDI+ support module. Not really something you could put together in a few minutes. It would probably take several hours.

I have to do it on visual basic 5 to modify an old software that work fine on w98 2000 xp etc

aicAlphaImage includes a folder "Usercontrol Only". Run "AlphaImageControl.vbp" and it will create an OCX. Then go to Project/AlphaImageControl Properties/Component and set Binary compatibility = True and point to the OCX you just compiled. This ensures that you have a unique GUID for this control.

Add the OCX to your project via Project/Components and the control should appear in the ToolBox.

I try, but where can I download aicAlphaImage and AlphaImageControl.vbp ?

You can download AlphaImage Control - PNG Compatible [VB6] here:

I have compiled ocx control and add to my own project.
I can view PNG images, but only in iteractive mode (open file -browse ...etc)
I need have a control property to view images from program running, and not in interactive mode, that is same as use internet explorer.
Sorry, this is not my soluction.
:(

Fine!
I'm incoming to pay points to danaseaman.
Only another dubt: the compiled AlphaImageControl.ocx is free or have to be purchased or paid or licensed or is trialware and expire....... ?

Hi,
I speak about AlphaImageControl.ocx with a VB Guru....
Is strange that it include ZLIB.DLL ..... (more emplojed for build spyware and malware)!?
Is real?
What about?

Zlib is included so that you do not need to install GDI+ on Win9x systems. It contains compression and decompression functions. Zlib is not Spyware or Malware. See http://www.zlib.net/ 

Thank, I see for it.

In any case I have open a new question about, and if you want 125 extra points go on

I have a remark.
DLL included in OCX is ZLIB1.DLL and not ZLIB.DLL

What is ZLIB1 ??
