        }

        //extension should be complete search strings like "*.png"
        //you might want to implement this in a second thread and display some progress

how do i define what the threashold is?

also i get an error

Error 1 'WindowsFormsApplication1.Form1.button1_Click(object, System.EventArgs)' must declare a body because it is not marked abstract, extern, or partial C:\Users\windows -7\AppData\Local\Temporary Projects\WindowsFormsApplication1\Form1.cs 23 22 WindowsFormsApplication1

any idea why?

Hello,

im trying to make a program that opens up jpeg files one at a time and look at there brightness and then if its past a threashold moves the file to a "keep" folder if not moves it to a "varify" folder

im new to C# so im not sure where to start

sorry if this has been asked before

i didnt think i could in C# can i use the same sort of code in c#?

and no its not my app im trying to hook into or i would just change the source of the app and edit my new code into it that would make things too easy

i was told that i couldnt do that in c# hence the delphi.

im new to programming in c# so i dont know too much in c# hence the stupid questions

yeah its a ie browser so if i try to call the Twebbrowser hmm i will try that thanks for your advise as that is what i wanted to block really

here is my delphi code but need a little help

uses ActiveX;

procedure WBFindDialog(AWebBrowser: TWebbrowser) ;
const
  CGID_WebBrowser: TGUID = '{is this my Target?}';
  HTMLID_FIND = 1;

var
  CmdTarget : IOleCommandTarget;
  vaIn, vaOut: OleVariant;
  PtrGUID: PGUID;
begin
  New(PtrGUID) ;
  PtrGUID^ := CGID_WebBrowser;
  if AWebBrowser.Document <> nil then
    try
      AWebBrowser.Document.QueryInterface(IOleCommandTarget, CmdTarget) ;
      if CmdTarget <> nil then
        try
          CmdTarget.Exec(PtrGUID, HTMLID_FIND, 0, vaIn, vaOut) ;
        finally
          CmdTarget._Release;
        end;
    except
    end;
  Dispose(PtrGUID) ;
end;

procedure TForm1.FormCreate(Sender: TObject) ;
begin
  WebBrowser1.Navigate('http://www.web.com) ; 
end;

procedure TForm1.Button1Click(Sender: TObject) ;
begin
  WBFindDialog(WebBrowser1) ;
end;

All i know is the Application was developed with Delphi

so if i can find the API call im might have a chance ?

thanks for you quick reply
it must have a API call as it has a browser in the middle of the application

i dont know if it can be done in C# or its a matter for unmanaged code i know a little about delphi if it needs to be done in that
