Is there a way to pass numerous properties to an .exe in a single property used as the .exe parameter...

[Superfreak3]

Hi all, 

This might be sort of a weird one.  We have a ton of configuration settings stored in a property that we want to pass to an .exe.  Is there a way to use a property to pass, let's say just two properties, for example by including them in another property...

COMBINEDPROPERTY=[FIRSTPROPERTY] [SECONDPROPERTY]

Then the custom action .exe is called with [COMBINEDPROPERTY] as its parameter/argument.  I was hoping that would then provide the various property values, but when I check what is passed to the .exe, I see [FIRSTPROPERTY] [SECONDPROPERTY] instead of something like firstvalue secondvalue.

Is this even possible?

I tried passing several properties in a single property and that didn't work.  I'm just passing all of my properties in as a delimited list with is split into an array and handled that way in custom action code.

Are you using a type 51 custom action to set COMBINEDPROPERTY ? And is COMBINEDPROPERTY listed in the SecureCustomProperties property?

Ah, I think I overlooked the set property method.  What I did to quickly test was to place [Property1] [Property2] directly in the Property table value.   I think I totally forgot about the set property custom action.  I'm confident that will work.

And all involved are in SecureCustomProperties.

Yes, the Value column of the Property table is of type Text, not Formatted, therefore properties are not resolved in that column.

Thank you Stefan.  It's something I've always wondered about, but never had the opportunity or need to try some like this.
