I have the following code (IP addresses changed) in a Delphi 7 project.
$IfDef starts a conditional compilation section. If Name is defined (by a prior occurrence of $Define), the source code after the $IfDef directive is compiled, up to the corresponding $Else or $EndIf compiler directive. Table 8-1 lists the symbols predefined by the compiler with. Not the answer you're looking for?

Undefines a compiler directive symbol - as used by IfDef: Author links: Buy Website Traffic at Buywebsitetrafficexperts.com Buy Proxies at.
Under project options:
- In the 'Directories/Conditionals' tab under the section marked 'Conditionals', I have a single definition: 'DEBUG'.
- In the 'Version Info' tab under the section marked 'Module Attributes', I have ticked the checkbox labelled 'Debug-build'.
In the above code example, the 'DEBUG' symbol is not defined, so the IP address is set to 123.456.789.12 instead of 127.0.0.1. What am I doing wrong?
This question is following on from Does Delphi's conditional compilation allow the defined symbols to contain values?

If you compile your project and there are no changes and the DCU is available on the path for the last non debug build then it will be used, causing this problem. Also make sure this unit is included in the uses clause of the DPR.
If you build the project it will force a recompile of all units added to the project.
I generally compile for syntax but always build for testing/deployment.
