Description: the first half of this program in Inno Setup instance inside there, behind the database backup and restore inside the instance is not easy to find online, I spent a great difficulty sentence try out , please Zhuanzhai marked to indicate the respect of the individual labor. Thank you!

Highlights: 

/ / Database backup file in a position to lay the package you want to restore the database to find the backup file first, then find the backup file before the software installation to where we need to know, which is the installation path. Installation in the registry to establish the relevant information, including software installation path recorded on the registry, please see the above write the INNO SETUP Registry Add read.

Why restore the database in this way, it seems to be around a circle, in fact, I also think that this may not be a good way, but I do not know any other way to get the data in the installation package ( file path) or software to be installed. {App}, {pf} such as this can not be directly used, why we have such a stupid way.

If any friends have a good way, please let me know. 

/ / Get the installation path from the registry, according to the path found to restore the database backup file.

if RegQueryStringValue (HKLM, 'SOFTWARE / *******', 'Server', ResultStr) then

The MsgBox (DB_PATH mbinformation, MB_OK); / / test to see the path right

oRestore.files: = db_path; / / Specify the backup file

oRestore.replacedatabase: = true;

oRestore.sqlrestore (sqlserver); / / perform the restore operation
