Usage of RAB on PC

labu

Hi All,

We are working at developping HMI's for our installations and would like to be able to use the same components for GTPU and PC Based. So far so good on TPU.

We are in need of support in order to build applications on PC as, for example, how to connect to a specific controller without using the NetScanner ( as this one is denied access when launched from a WebPage).

 

------------

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Source Error:

Stack Trace:

Version Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573

-----------------

 

Secondly, once gaining access to a controller in a windows application, we get the system hanging (application locking when executing the line in the debugger) while trying to get the rapid data

private void button1_Click(object sender, System.EventArgs e)
{
ABB.Robotics.Controllers.RapidDomain.RapidData MyData;
MyData = MyController.Rapid.GetRapidData("T_ROB1","ComTest","toto");
label1.Text = MyData.ToString();
}
 
Same code is doing fine on the GTPU.
Version used is RAB 5.05 from SolutionBank
Any help Welcomed,
 
Best Regards,
Laurent

The PC CAPI is not in the GAC yet. It will be in 5.06 release coming soon.

ASP:NET has not been covered as a development platform by the product project right now. What you can do to continue is to try to add the ASPNET account to the Administrators group. If this doesn't work, the problem may be related to .NET code access security. See Start Menu/Program Files/Admin Tools/Microsoft .NET 1.1 Configuration.

Hi,

 

Thanks for information, as far as ASPNET restrictions, I found a good article about Access Restriction

http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q817033

And a possible solution

http://weblogs.asp.net/pleloup/archive/2003/08/25/25226.aspx

This surely needs to be used with caution as it might grant more provileges than expected in some Web applications.

 

Looking forward 5.06
