(Delphi) Define global flag?

Recommended Posts

iChallengeYou

First a happy new year :)


 


So I want to define a global flag which can be used everywhere in the project.


So in example i want something like this:



isUnpackMe = false;
Button1.Click()
{
if (isUnpackMe)
{
ShowMessgae('This is an unpackme');
}
}

So i don't want to declare isUnpackMe as an variabele but want to define it like the pre-defined {$IFDEF CPUX86}.


 


Does anyone know how to do that?

I think this is what you mean:

var  text : string;begin  // Set our code into test mode  {$Define TESTMODE}  text := 'We are in test mode';  // Display the value of text if we are in test mode  {$IfDef TESTMODE}  ShowMessage('text = '+text);  {$EndIf}  // Switch off test mode  {$UnDef TESTMODE}  text := 'We are out of test mode';  // Display the value of text if we are in test mode  {$IfDef TESTMODE}  ShowMessage('text = '+text);  {$EndIf}end;

You can also use M4 macros for a bit more functionality. Always wondered why Delphi has no preprocessor..  :scratch:
