expression.IsCurrentUser(ByVal bstrUsername As String) As Boolean

expression Required. An expression that returns a reference to the User object.

bstrUsername Required String. The user name in the format of "domain\username."

returns A Boolean value indicating whether the specified user name matches the name of the current user.

## Security Level

0: Can be accessed without restrictions.

## Remarks

Even though the IsCurrentUser method is marked as security level 0, it is not always accessible. When a call is made to the IsCurrentUser method, InfoPath first performs a security check to determine if access to this method is allowed. The security check confirms whether the calling code is trusted or not and it determines the location of the calling code.

If the calling code is trusted (as it is when, for example, the IsCurrentUser method is called from an installed or signed InfoPath form template, or from trusted external code, such as an executable file on the local computer), InfoPath will allow full access to the IsCurrentUser method.

If the calling code is not trusted (as in the circumstance of a call coming from a domain-based InfoPath form template or from script executing in Microsoft Internet Explorer), InfoPath first checks where the call is being made from. If the call is from code that is not trusted in an InfoPath form template at a URL such as "http://www.contoso.com/example.xsn", then the call is from the Internet zone. InfoPath denies access to the IsCurrentUser method for all calls that are not trusted coming from the Internet zone. If the call is from a URL such as "http://contoso/example.xsn", then the call is from the Intranet zone. For a call that is not trusted from the Intranet zone, InfoPath checks whether the Internet Explorer user authentication settings allow automatic logon (in the Intranet zone only or for every logon). If Internet Explorer is configured for automatic logon, then InfoPath allows full access to the IsCurrentUser method. Otherwise, access to the IsCurrentUser method is denied.

Note This object model member is not supported when the Disable Service Pack features option on the Advanced tab of the Options dialog box in InfoPath is selected or when Microsoft Office 2003 Service Pack 1 or later is not installed. Any form that implements this object model member in its code will generate an error message if it is opened in InfoPath when service pack features are disabled or unavailable.

## Example

In the following example, the IsCurrentUser method of the User object is used to determine if the current user equals "UserDomain\NancyDavilio".

    var fUserMatched;
    fUserMatched = Application.User.IsCurrentUser("UserDomain\NancyDavolio")
