I like display pictures in image vb5 control .
jpg anfd gif are supported without problem.
How display also PNG pictures?
Please, complete code because I'm novice in vb programming.
I include example to finish/modify.

THE FILE UPLOADER BLOCKED ME SOME EXTENSIONS.
To use it rename the files:
form1frm form1.frm
form1frx form1.frx
progetto1vbp progetto1.vbp
progetto1vbw progetto1.vbw

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.

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 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.
:(

At runtime you can load images from File, Resource, Array, Clipboard, Handle, or StdPicture:
Option Explicit
 
Private Sub Form_Load()
   aicAlphaImage1.LoadImage_FromFile (App.Path & "\firefox3.png")
   'aicAlphaImage1.LoadImage_FromResource VB.Global, "Custom", "LaVolpe"
End Sub

Open in new window

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/
