Hi

We are currently evaluating the ImageBox component and would like to know if it is possible to display an Icon which is embedded in the application as a resource? We have got this working for bitmap resources using DispayFromHBitmap but not icons.

Cheers

Hi Tom,

Hi Loic

It's Visual Dataflex 14.0 but it uses the windows api to access the images from the resource, i.e. LoadImage and passes IMAGE_ICON. Using DisplayFromHBitmap returns an error 7, ViewerWin32Error, should it work or should I be using another command. I can display the icon when I load it from disk using DisplayFromFile but need to display it from the resource.

Cheers
Tom

OK Tom, I understood.

Unfortunately there is no function to display an icon from an icon handle. Maybe you can find a way to convert the hicon to bitmap ?

In GdPicture Pro we have a method called CreateImageFromHICON() which seems to be what you need. For the next release I will add a DisplayImageFromHICON() in the ImageBox control.

Best regards,

Tom, we just released the last edition. I think nexte releases will be available in end of January 2009 now.


Here an exemple using the Win32 api to convert an HICON to an HBITMAP. Maybe you can convert it into your programming language ?

Hi Loic

Also can we put ourselves to beta test the next version? How does your beta program normally work?

Cheers

Hi Tom,

Unfortunately we can't provide beta edition but only with the same architecture that the current edition (same properties, same methods...). This for binary compatibility requirement.

However i have an idea. Could you tell me what is the returned value of the DisplayFromHBitmap() method in your case ?

Best regards,

Loïc

Hi Loic

When using DisplayFromHBitmap to get the icon resource it returns error 7 - win32.

HI,

You can try the last release available. I've added HICON support into the DisplayFromHBitmap() method !
For the next major release you will be able to use directly the DisplayFromHICON() method.

Best regards,
