Until someone writes proper string visualisers for the Delphi debugger…

A few tricks to write long strings to files when the Delphi debugger cuts them off (just because they like using 4k buffers internally);

• TStringStream.Create(lRequestMessage).SaveToFile('c:\temp\temp.txt')
• TIniFile.Create('c:\a.txt').WriteString('a','a',BigStringVar)
• TFileStream.Create('c:\a.txt', fmCreate or fmShareDenyNone).WriteBuffer(Pointer(TEncoding.UTF8.GetBytes(BigStringVar))^,Length(TEncoding.UTF8.GetBytes(BigStringVar)))

They all work form the debug inspector, but they do leak memory. See comments below.

I am not sure if the buffer is not a little bit bigger, but still to small in recent versions. To quote myself “Cannot say it often enough – do use ReadProcessMemory for your visualizer” twitter.com – Uwe Schuster on Twitter and just build a simple visualizer.

[WayBack] @UScLE: Cannot say it often enough – do use ReadProcessMemory for your visualizer, but well I forgot JSON documents are never longer than 4K.
