NT Service Heelllpppp!!!

[johnfermor]

This great NT Service code by Richard Eikeland was submitted some time ago but I can't get it to work as I get a "Line 28: Constant Already Declared with a different value: #SERVICE_ALL_ACCESS".

This question was also asked by AAA_2500 when the info was last posted (Dec 2003) but hasn't been answered.

Have I missed something here? I can't see any earlier declarations. Has the routine been broken by a PB update maybe? Is there a workaround?

Thanks everyone....

If a constant is already declared, you give it another name...

[Karbon]

Or don't define it yourself as it's already declared!

[Pupil]

PB has quite a few precompiled constants already in '.res' files located in the '\residents' folder the constant in question is probably already there inside the 'windows.res' file. So you can do one of two things either use the one that is precompiled(assuming it's value is correct) i.e. comment out the line assigning the value to this constant in your program or you can just use a different name for the constant in your program...
