Hi All!

I want to get Datas out of a WebSite eg. a "string-gadget" on a website and the selected item of a combobox gadget after pressing a buttongadget.

How could I realize that? I suggested the action of a "GO" button will start a small .exe with commandline-parameters of the stringgadget and the combobox gadget. but how to realize it!?

Anyone have suggestions?

Mike

You must write a win-CGI program
The webserver will start your app, with a filename as commandline parameter.
This file is in *.INI format (mostly with .tmp extension)
in this file will be the name of the "Content File" , this holds the data of youre POST action.
Also the name of the "Output File", this file is send to the user after he pushed the button and the CGI app is finished.
Some webservers also put your form data at the end of this file.

example of html file with button

Code: Select all



CGI Example



Parameter

some webservers start your app with 3 parameters, the input file, the content file, and the output file
But most webservers support the first way.

Example of purebasic app "purecgi.exe "that must be placed in CGI-WIN directory on webserver, writes the name of the input file in cgitest.txt

Code: Select all


SourceFileName$ = ProgramParameter()
If OpenFile(1,"cgitest.txt")
  WriteStringN(SourceFileName$)
  CloseFile(1)
EndIf

Delay(20000)

Note the delay(20000), i needed this to be able to catch the input file, files only exist as long as CGI app is running. They are created by the server in the current TEMP dir.

example of the input file from OMNIhttpd webserver

Code: Select all

Thanks for fast answer but your method gives me a problem:

The GUI of my application should be displayed in a Browser-Window on a local machine and there is no CGI support or webserver installed.

Edonkey or Emule for eg uses a ED2K:// Link in the URL field wich starts the application by clicking on this link and giving parameters to it. I searched through the source-code of Emule (open source) and my registry and found some entrys. I need to check if I get it work on my own application.
