ReadINIStr and WriteINIStr

Thank you for your reply Sir. I was able to write the ini string but I still don't get how to make the launcher compare the volume serial number to another volume serial number.

For example; the first installation writes the Volume serial number in ini string and saves the ini file in $EXEDIR\DefaultData directory. Then if you copy the whole installation directory in another usb or volume, the launcher will then get the current volume serial number and compare it to the serial number which the installer saves in the $EXEDIR\DefaultData directory.

If the two serial number didn't match then the launcher gives a message saying "portableapp has been copied to another drive." then the launcher exits, thus copying the whole portable app install directory makes it unusable.

The thing is wanted to know how to prevent the copying of my portableapps to other drive.

This is part of the code that I use:

Function GetDiskVolumeSerialNumber
${GetRoot} `INSTDIR` $R0 <-(I used this to specify that the volume was a removable drive and not a system drive.)

!define GetVolumeInformation "Kernel32::GetVolumeInformation(t,t,i,*i,*i,*i,t,i) i"
System::Call '${GetVolumeInformation}("$R0",,${NSIS_MAX_STRLEN},.r0,,,,${NSIS_MAX_STRLEN})'
FunctionEnd

Please correct me if you found some errors with the codes that I use.

Thank you Sir.
