Should be easy for someone who knows:

How do I change the icon image for an ActiveX control that I am trying to build in Delphi 5?

By default it comes up as those funny 3d shapes.

I know how to do it when creating custom VCL components (ie you create the .dcr file using image editor), but it doesn't seem to work on ActiveX components.

- Start Delphi's image editor.
- Create a new dcr-file.
- Add a new 24x24 Bitmap to the content.
- The name should be like TMyActiveX
- Edit the image
- Save it with the same name as the .pas file except that it must be .dcr now.

Forget the above. When you import the ActiveX Control into delphi, the .dcr file is created automatically in the imports directory. Just edit that one.

(Delphi 5)

I don't really want to ask all of my customers to edit the icon every time they import my activex control! Anyway, this doesn't work for VB users etc.

There must be a simple way to change the icon that is compiled into the .ocx file.

edit the bitmap from the .res file and rebuild the project to get the new icon in your activex ready for deployment.

1. Open you ActiveX projects .res file ( Your projectname.res in the same
dir as  your project ) in the image editor.
2. Edit the Bitmap 1 to your image.
3. Close the Bitmap editor.
4. Save  the Res File and exit.
5. Open your ActiveX project and then do a Build All.
6. Remove the ActiveX control from the associated package file and compile
the package file. You should then get a message saying "This control is no
longer registered.. ".
7. Import the ActiveX Control back into the package and recompile the
package. You should then get a message indicating a new control has been

Don't know why it didn't work the first 10 times I tried.

Maybe the Build All...
