hi, can anybody tell me how do i go about building an ISAPI application. the application which i intend to build is as follows: the user will select some options from a web page(options regarding some images) and then click the get button. then the image selected by the user should get displayed on the page. in html this is simple but this is only a test application.in the final application the user is going to select the name of another application and also send some data required by that application. the background program(i.e. the ISAPI extension ) will have to check whether the application required by the user exist and then pass on the data to that application and wait for the result. when it obtains the result it will show it back to the user. so as a first i want only to send back some images. can anyone tell me how to go about this application. i tried using the sample programs on code project but they did not have any explanation and did not worl properly. Lastly is there anyother better way to build this application other than what i have said(if it is the correct way) thanks aditya
