I have modified this code from https://www.vbcoders.com/vb/scripts/ShowCode.asp?txtCodeId=68349&lngWId=1 (many thanks to David for his submission). Modifications: Added a richtext preview window, that makes it look like the VB IDE. Added a 'add constants & types' checkbox when you're looking through declarations. This will grab whatever constants and types are listed in the declaration, and append them to the preview. Added ability to search through constant+enum values. The reason I modified this, was I because I was intercepting windows messages and thought this would be a fast way to see what the messages might mean... So in the search textbox, you can now either look for a declaration, constant, type or enum as before, but you can also enter in values. For example, let's say you've subclassed a window, and all these numbers are coming through your debug window, how are you meant to know what means what? Well, if you enter &H9 in the textbox, all the constants and enumerations with the value &H9 will be shown in the preview window. Pretty handy if you ask me... There were a few other bugs I found in the beginning which I should have noted down, but I just went ahead and fixed them. From memory, one of them was it was looking in the wrong listbox for the 'subs' (thinking it was looking in the declaration listbox).
