How to fill web page fields from a Win32 Delphi application.

Hello.

I need to fill some web page fields with data that is already in a Windows 32 Delphi application.

The problem is that I don't know the name of the fields of the web page because it has
frames and the right mouse button (to see the source code) is disabled. If I use the browser's
menu: View/"Source code" I only get this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
      <HEAD>
            <TITLE>Logistics System 2.01</TITLE>
            <meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
            <meta content="C#" name="CODE_LANGUAGE">
            <meta content="JavaScript" name="vs_defaultClientScript">
            <meta content="http://schemas.microsoft.com/intellisense/ie5" name="vs_targetSchema">
            <SCRIPT language="javascript">history.forward();</SCRIPT>
            <SCRIPT language="javascript">self.resizeTo(1024,768);</SCRIPT>
      </HEAD>
      <FRAMESET border="0" frameSpacing="0" rows="71,*" frameBorder="NO" cols="*">
            <FRAME name="frmEncabezado" src="wfrEncabezado.aspx" frameBorder="no" noResize scrolling="no">
            <FRAMESET frameSpacing="0" frameBorder="no" cols="184,786">
                  <FRAME name="frmMenu" src="wfrMenu.aspx" frameBorder="yes" bordercolor="#005fb3" scrolling="yes">
                  <FRAME name="frmTrabajo" src="wfrBlank.aspx" frameBorder="no" scrolling="yes">
            </FRAMESET>
      </FRAMESET>
</HTML>

In the Windows 32 application I have all the data that the users have to type manually to the web form, and I want to copy the data automatically when they push a button "copy data". The web application is from another company and I
have no access to the code.

Thanks in advance.

As I extensively use javascript I would suggest it. Because you dont know the field name where you want to set the value you wil have to find the correct field first and then set its value.

Here is the javascript that goes through all the elements and displays all of them in alert.

var
s : TStringList;
begin
s := TStringList.Create;
s.Add('javascript:function myselect() {');
s.Add('var ecnt=document.forms[0].elements.length;');
s.Add('var i;');
s.Add('var elist="";');
s.Add('for (i=0; i<ecnt; i++) {');
s.Add('el = document.forms[0].elements[i];');
s.Add('elist=elist+el.name+"="+el.type+"\n";');
s.Add('}'); //end for
s.Add('alert(elist);'); //end for
s.Add('}; myselect();');
WebBrowser1.navigate(s.text);
s.Free;
end;

I hope this will help you. and once you know the field name setting its value is pretty simple.

See the following on how to set values through javascript.

You need to obtain the HTML source from the frame that has the elements you want to fill in.
Then you can call the functions in my post here to fill them.
http://www.experts-exchange.com/Programming/Programming_Languages/Delphi/Q_20848037.html

You'll have to modify the sAction and sMyFormTitle variables and the parameters in the array passed
to FormSubmit to match what is in the form on the frame.

This works on a running instance of IE.
