Load DLL from webpage

I need an ActiveX OCX written in C++ which will be embedded into a webpage and called from Javascript. It should have public methods which should do the following:

1) Download a file from a specified URL to a folder in windows. The URL and the Folder name will be passed in from javascript. If the folder name is empty, then the file should be downloaded to the user's local temp folder (please make sure that the string passed in from javascript is compatible with the string type you use in C++)

2) Load a DLL using Loadlibrary. The name of the DLL and the folder it's located in will be passed in as javascript strings. If the folder name is empty, use the users local temp folder as the foldername. The DLL loaded using LoadLibrary will have 1 function. It has the following prototype

void queryParams(char *inputString, int len1, char *retString, int len2)

inputString is a pointer to a string of length len1 and retString is a pointer to a string of lenght len2.

3) Your OCX will have a public method also called queryParams, but it will be called from javascript. It will take accept 1 parameter as a string and will return 1 parameter as a string. It will simply forward the string passed in onto the queryParams function in the DLL. The DLL will fill the retString parameter with a return value and your OCX will return it back to javascript. (The OCX will basically act like a bridge between javascript and the DLL)

4) Free the DLL
