We have a aspx page which writes a value to a textbox in two webhosts, Ix and godaddy...
When trying to retrieve the value from a VB6 code, it works fine with Ix but gives an error (object doesn't support this property or method) in godaddy.

The vb code uses where Autoreg is the Input
WebBrowser1.Document.Form1.AutoReg.Value

The link to the exe which retrieves the value is in the below link

http://www.megaupload.com/?d=L7WAP04W

In the exe command 1 button is for ixwebhosting and command 2 is for godaddy

Can anyone tell what is the difference in two hosts?

It seems to be a problem in your exe, maybe godaddy is sending you extra HTTP headers that you need process or something.

HTML form on http://saralsolutions.com/test2/sarl_sol.aspx doesn't have a name attribute. that might be throwing off your object reference WebBrowser1.Document.Form1.AutoReg.Value.

http://saralsolutions.com/test2/sarl_sol.aspx
<form method="post" action="sarl_sol.aspx" id="form1">

Open in new window

Change it to:
<form method="post" action="sarl_sol.aspx" id="form1" name="Form1">

Open in new window


On http://trueirr.com/test/Test2/sarl_sol.aspx it had the name parameter on the form, but I can access it now, I guess you took it down, np, try the name parameter.

Is this a server side form? Although I didn't see runat="server" on them.
AFAIK ASP.Net alters the id and name of the server side forms, maybe that has something to do with this.

Try using a regular .html file instead of .aspx to see if that is the case.

yes, it is a server side form.. I have specified runat="server" .. How can I pervent it from changing(only name is missing, id attribute is shown)?
Server is using IIS 7.5(Windows Server 2008)

I'm not sure if this is supported on VB control, but you can try to skip the form and access the element using following method:
WebBrowser1.Document.All("AutoReg").Value

Open in new window


P.S:
I'm advising you only with my former VB experience, you might want to get some .Net experienced eyes on this be using the "Request Attention" link.

thank u for the reply.. and it works!
But the problem is our product already has the old code, and it is a tedious and tough process to replace this in all our customer places.
So, it is essential to make the old code work in the new web host.
Is there a way that can be done?

It could be due to the difference in the .Net framework versions the web hosts use.
http://saralsolutions.com has version 4 and the other seem to have an earlier version. Check on your hosting configuration if you can switch to the .Net framework version your app worked with, you might need to get the assistance of the hosting service for this.

Thank you for your assistance sudaraka..
Yes It was because the support for name attribute of form was removed in asp.net 4.0.
It worked when I changed the .net version to 2.0
