Silently installing an inf file from your delphi application
<![CDATA[
Question:
My self-written install program needs to install a 3rd party tool which comes with an .INF file. How do I call it up to install invisible ('silent install')?
Answer:
The INF file format has been around for many years at least since Windows 3 and it has many options including modifications in the registry, driver installation or date and version control. There are even free tools available to generate INF files.
Executing them from a Delphi application is no problem if you use the function shown below. Simply pass the path to the .INF file and handle of your form (use 0 if you have a console application).
uses
ShellAPI;
function InstallINF(const PathName: string; hParent: HWND) : boolean;
var
instance: HINST;
begin { InstallINF }
instance := ShellExecute(
hParent,
PChar('open'),
PChar('rundll32.exe'),
PChar('setupapi,InstallHinfSection DefaultInstall 132 ' + PathName),
nil,
SW_HIDE);
Result := instance>32
end; { InstallINF }
