Hi all. I inherited this code from a contractor. It is a .NET user
control that runs on the client side (ie) on machines with the
framework installed. I have been mucking around to get it work for a
couple of days now, and am growign really frustrated. I need to
expose an Import method on the ImportControl and have it accesible to
javascrip in the browser.

If I remove the InterfaceType and ClassInterface attributes, compile
and then view the typelib created by tlbexp, it does not show any
methods on the class. If I add the attributes, the methods are
listed... ...but when I invoke throuhg the web nothing works. The err
is: "Object doesn't support method or porperty"

....PLEASE HELP ME... Thank you -- code posted below

[InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IImportControl
{
string Import(string workingDirPath, string fileName, string
fileType) ;
}

[ClassInterface(ClassInterfaceType.None)]
public class ImportControl : System.Windows.Forms.Control,
IImportControl
{
private System.ComponentModel.Container components = null;
public ImportControl()
{
InitializeComponent();
}

public string Import(string workingDirPath, string fileName, string
fileType)
{
return "" ;
}
}

CLIENT SIDE

<OBJECT id="ExportObject"
data="data:application/x-oleobject;base64,IGkzJfkDzxGP0ACqAGhvEzwhRE9DVFlQRSBIVE1MIFBVQkxJQyAiLS8vVzNDLy9EVEQgSFRNTCA0LjAgVHJhbnNpdGlvbmFsLy9FTiI+DQo8SFRNTD48SEVBRD4NCjxNRVRBIGh0dHAtZXF1aXY9Q29udGVudC1UeXBlIGNvbnRlbnQ9InRleHQvaHRtbDsgY2hhcnNldD13aW5kb3dzLTEyNTIiPg0KPE1FVEEgY29udGVudD0iTVNIVE1MIDYuMDAuMjgwMC4xMjI2IiBuYW1lPUdFTkVSQVRPUj48L0hFQUQ+DQo8Qk9EWT4NCjxQPiZuYnNwOzwvUD48L0JPRFk+PC9IVE1MPg0K"
classid="clah.dll#clah.ImportControl" VIEWASTEXT>
</OBJECT>

parent.document.getElementById("ImportObject");
ImportObject.Import("","","")
 
Does the client side have the correct permissions ?
I had the same problem and had to give full trust on intranet to make it
work
To make this check .Net Wizards on Adjust .net Security choose "Make changes
to this computer" and give full trust to Local Intranet.

I think this is your problem ;)

Yes it was permissioned correctly on the client side. The issue was
the server Execute permissions were set to scripts and executables.
As a result IIS was trying to run the dll request as an ISAPI
extension, rather than just serve the binary to the client.

Thank you though
