dotnet web services
group:Starting Windows Application from .NET Web Service
dotnet web services:
which consumes customer information and then attempts to create a new customer account in an accounting application (i.e. QuickBooks). For unattended access to the accounting application, an exception for the application attempting to access the accounting application must be granted through the accounting application user interface the first time. I am able to activate this exception dialog box through a Windows application, however, calls to my web service results in an error, essentially telling me that I don't have the necessary exception, but not activating the exception dialog box in order to grant the exception. Once I have the exception, the web service can access the application without user intervention. Something is preventing the web service from activating the necessary accounting application exception dialog box. I have attempted numerous configurations including the following: running the application pool under an administrative account (for testing purposes), setting the "Allow service to interact with the desktop" property for the World Wide Web Publishing and IIS Admin Service, verfiying the ACLs of the appropriate folders, and changing app pool uesr accounts. In addition, there is a configuration where I can use an out-of-process COM server supplied by accounting application to perform the same operation. This configuration yields the same error. What other configuration issues might prevent the web service from successfully activating the exception dialog box? Is there an issue that would prevent the web service from interacting with the desktop? Alternatively, Is there a way to configure a specific security context for the accounting application? I would appreciate any insights. Thank you.

Surely it's possible that our answer would be different depending on which exact exception you received? Please post the result of ex.ToString() so that any InnerException chain is included. Second, where do you expect the dialog box to display? The web service does not have a display device associated with it. How were you planning on filling in the fields of the dialog box? There is no keyboard associated with the web service. Finally, you should really ask the QuickBooks developers this question, as this is probably not a generic "how do I run any Windows application from a web service" question, but rather "how do I run this particular QuickBooks command from a web service"? -- -------------------------------------------------------------------------------- John Saunders | MVP - Windows Server System - Connected System Developer
Thank you for your response. The error message is QuickBooks specific and
pretty much as described, but here is the exact text: "This application is not allowed to log into this QuickBooks company data file automatically. The QuickBooks administrator can grant permission for an automatic login through the Integrated Application preferences." The exception dialog box is launced from the QuickBooks application the first time the "integrated application" (in this case the web service) tries to access the QuickBooks file. The idea is to have QuickBooks open on the web server, call the web service, have the open QuickBooks application display the execption dialog box (a QuickBooks form), fill in the dialog box for the exception, and click OK. Subsequent calls from the Web Service will see the previously granted exception and be allowed access automatically. This is similar to how MAPILabs Outlook Security Add-In functions for granting security exceptions to Outlook from third-party applications. Regarding point number three, I have traversed the QuickBooks developer information and newsgroups exhaustively prior to this post. I am not the first to blaze this trail according to the QuickBooks newgroups, but there are really no comprehensive replies that one can use to discern the appropriate configuration. Windows Server 2003 is not considered a supported QuickBooks operating system although shared QuickBooks files routinely reside on servers with this O/S. Given the lack of QuckBooks related information, I decided to try and approach the issue from a more general IIS configuration standpoint. From what I have read in the IIS/Web Service newsgroups, others have tried similar configurations but there solutions (see first post) have not worked in my particular instance. Thanks again.
