How do I use OutputDebugString to print a message that's in a string variable?
Solution 1
You can write a wrapper function to take care of the variables passed to OutputDebugString
as it expects a PChar.
Something like:
procedure DebugMsg(const Msg: String);
begin
OutputDebugString(PChar(Msg))
end;
There is a useful reference for debugging techniques here.
And if your Delphi is a bit rusty there's the ever useful Delphi Basics site. I use it a lot :)
Solution 2
In addition to the 2 answers you got about OutputDebugString() and WriteLn(), for debugging there is a better solution: CodeSite from Raize Software (see http://www.raize.com/DevTools/CodeSite/Default.asp ).
If you have Delphi XE, that should already come with an somewhat reduced functionality version of CodeSite.

I recently had to do some changes in some Delphi code. Therefore, I have some basics questions:
- Generally, how do I output to the console?
- How do I output to the console with
fx
that is a string variable?
I started using
OutputDebugString
, but I couldn't get it working with a variable.
