One, with VC + + Write a dynamic link library files such as Install.dll
Implementation features:
1, automatically change the security level of IE to enable unsigned ActiveX controls to install executable EXE files ready;
2, automatically determine whether the browser controlled by the client installed the installation program;
3, automatically judge the browser's operating system, and turn to the corresponding client program installation interface;
4. Automatically judge the installation path of the client program of the controlled end;
5. Keep ...
