IEMBitmap.LoadFromResource crashes when trying to load the resources from a 64-bit EXE file:

Here is the project to reproduce the error:

attach/PeterPanino/20241011104749_TIEMultiBitmapHelperLoadFromResourceTestv2.zip
86.34 KB

How can the crash be avoided?

The documentation says only: "Appends the specified types of resources from PE files like EXE, DLL, OCX, ICL, BPL, etc from a module, such as an EXE file."

It does not mention 32-bit or 64-bit.

ImageEn 13.6.0
Delphi 12.2
Windows 11

I have tried to limit the resource types to Bitmap and GroupIcon:

ImageEnMView1.IEMBitmap.LoadFromResource(ThisExeFile, [ietrBitmap, ietrGroupIcon]);

In this case, the crash does not occur, but the Bitmaps are empty:

It is unclear whether the Bitmaps are shown empty only with this specific EXE file or whether this is a general limitation.

I have now improved my project:

1. Loading only GroupIcon resources due to the 64-bit limitation
2. Applying an automatic Filtering system that shows only the icon resources with the largest dimensions in the EXE file

Hi Peter

Your demo works fine when I test it here on various EXE files. Is there are particular EXE/DLL I should load to reproduce the error?
