How can I show the contents of a TStringList in the debugger?

Question

I want to display the entire content of a TStringList while debugging the application. Instead I just get pointers. The Flist is showing only the address.

Answer 1

If you are using Delphi 2010 or later, the debugger allows for this using debug visualizers.

For older versions, you can dump the contents of the Text property in the Watch window or using OutputDebugString, but that's difficult to read. You could set up watches for each element of the list, but that's only practical for very short lists.

I would probably use an external logging app like CodeSite or SmartInspect that let you dump the contents of a TStringList in a single call.

Answer 2

Inspect the Text property. It's the concatenated version of the stringlist.

Answer 3

Since i´m using BDS MMVI, i´m using an "ultra clever smart" method for that kind issue, i use it for large xml documents. I start context file editor (very capable free text editor writen in delphi by the way). On the debugger window a just do a FList.SaveToFile('contents.txt'), since context can monitor file modifications i can see whats happening in my xml files.

Sorry for the "clever" joke but it does work for me.

Peace
