StringCompare if not empty

[martijntijn]

I use the following script to check for installation of the .NET Framework:

code:


StrCpy $2 0

  loop:

    EnumRegKey $1 HKLM Software $2

    StrCmp $1 "v2.0.50727" done

    IntOp $2 $2 + 1

    !StrCmp $1 "" loop

    MessageBox MB_OK "NoMsFramworkInstalled"

  done:

I want to loop trough my Registry is the key 'v2.0.50727' exists. Every key I compare with "v2.0.50727". When true go to 'done', when false reloop.

[Line 6] If $1 is not empty, reloop. What is the right syntax for this line? And will this code work?

StrCmp $1 "" 0 loop

[kichik]

code:
StrCmp $1 "" 0 loop

This would be much easier with the LogicLib:

code:
!include LogicLib.nsh

#...

StrCpy $2 0

${Do}

	ClearErrors

	EnumRegKey $1 HKLM SOFTWARE\Microsoft\.NETFramework $2

	${If} ${Errors}

		${Break}

	${EndIf}



	${If} $1 == "v2.0.50727"

		MessageBox MB_OK found

		${Break}

	${EndIf}



	IntOp $2 $2 + 1

${LoopWhile} $1 != ""
