web page input to C++ code
hi all
I have a web page that contains a button. on click of this button an image is loaded from my hard drive.
I want to send this image as the input to my C++ exe file.
Any pointers as how to do this.
Any documentation for the same would be of great help.
Thanks

Where will the executable be? In the web server? Or in the end-user's computer?
If on the server, then your web page should be able to tell if the button was pressed, and then spawn your C++ executable file in the server side passing say, the file name of the image as part of the command-line arguments. This should be easy enough for pages in PHP, ASP, or ASP.net.
If on the end-user's computer, then things get complex really fast. Most (if not all) browsers will stop a web page from spawning an executable in the end-user's computer due to security reasons. You'll have to play along the rules of the browsers to get it to work.
In Windows, Internet Explorer would allow the web page to run your executable through an ActiveX component that is marked as Safe for Scripting. There are two ways to mark and ActiveX component as such: 1. Through the windows registry, or 2. The ActiveX component implements IObjectSafety. I have done neither, so I don't think I can help with these.
I don't know the rules of Firefox, if any, and much less other web browsers or browsers in Unix/Linux or Mac.

Since this is a C++ forum, you might be better off asking elsewhere.
