Need help with System::Call Function
Hello,
i need help with my installer. I have wrote an installer script for an TAPI Client Installation. My selfmade resolve of TAPI Registration is a little "BUGGY". I used Registry Commands for example. WriteRegDword, ReadRegDword etc. and copy the values in a ini File at the installation. If the user, uninstall the TAPI Client, the uninstaller read the values in the ini and del the Registry Entry on this Position. That´s works but only if the user doesn´t change manually the registry of TAPI Clients. And negative too, the user must restart his/her system for correctly working of the TAPI Client after Installation.
But i have founded two System Call Functions that i must include in my script for killing this BUG:mad:
System::Call 'tapi32::lineAddProvider'
http://msdn2.microsoft.com/en-us/library/ms893340.aspx
System::Call 'tapi32::lineRemoveProvider'
I have no idea in which way i must set the parameters that this Function work. i read all nsis.sourceforge topics but it was impossible for me to execute the call correctly. I´m stupid. Please help me.
Useful for helpers:
Windows-Registry-Path for Tapi-Providers
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers
Example installed ProviderFilename:
myTAPI.tsp - installed in $sysdir
