• Visual Studio Models relationship

  Hi, When I run Domain Model project a new instance of VS (Experimental Build) is opend. I am using Class Diagram type. I created 2 files with my extension, for exmaple Test1.mydsl and Test2.mydsl. Test1.mydsl has Parent object. Test2.mydsl has Child object. I need to have a inheritence relationship b/w these objects. Is it possible that one object lives in first dsl file and another from second dsl file inherits from it Because I have a huge model and it would be better to separate sub-model in different files. Thanks. Hi, The DSL Tools don't natively support cross references between models. The good thing is that the DSL Tools team just released a Power Tool that does support thi ...Show All

• Windows Forms Overriding an 'invisible' property

  UserControl has a property called Text which is hidden from the user at design time. How do I override Text such that the user can 'see' it This is untested code, but I'd say just your usual override should work: public override string Text { get { return base .Text;} set { base .Text = value ;} } If that doesn't work try using the new keyword instead of override. ...Show All

• SQL Server Process task hangs running bcp

  We are attempting to use Microsoft SQL Server Integration Services Designer Version 9.00.2047.00 to run a BCP command from a Process task. We are able to do so without a problem when running it interactively, but when run as a SQL Server Agent job the bcp process never completes and the job hangs indefinitely. We also tried using a Script task for this, with the same result. Has anyone else run into this problem Thanks, Ron Thank you for the suggestion, Duane. In this case, though, the package executes, it just hangs on the Process task that executes the BCP command. The security level of the package is DontSaveSensitive, and the Agent service account has full permissions to the fil ...Show All

• Visual C++ Decorations on C++ DLL function declarations really needed?

  I used the _stdcall decorators on the Visual C++ function definitions and declarations, but I couldn't get communication between the DLL and the Visual Basic application that was trying to call the functions of the DLL.. When I removed the declarations from the VC code almost completely (all but for the DLL_Main function definition), it worked fine.  Is there any disadvantage to using this approach   Everyone I communicated with about it , including my boss and people that answered the MIcrosoft help posting that I put up, stated that you have to use those decorations.  Why is that   It works fine without it so far.  My boss will be back from travel tommorrow.  I was hoping to find out today so I can make ...Show All

• Visual Studio Tools for Office VSTO Outlook 2003 Add-in Deployment problems

  I've had a lovely little add-in now working on my machine for a while, and yet I haven't been able to deploy it successfully, not even on my own machine once. The program works absolutely perfectly on my machine when debugging and running through Visual Studio, but when deployment comes, the common error "Not loaded. A runtime error occurred during the loading of the COM Add-in" occurs. I've now created the simplest of simple add-ins, that simply display "HELLO WORLD" in an attempt to deploy that, to then further, deploy mine - still no look. The main blog I found which seemed to cover the most problems was http://weblogs.asp.net/mnissen/articles/427504.aspx I created the installer class that i read about ...Show All

• Visual Basic Can't add DLL's from GAC through References-Add Reference

  Hi all, I need added a DLL to my GAC (C:\Windows\Assembly) but when I want to add a reference to this newly added DLL I can't seem to add through right-clicking on 'References->Add Reference' and then selected the 'Browse' tab in the 'Add Reference' dialog. I can locate the dll, but when I click 'OK', nothing happens. Any ideas I agree with you and think it is a shame that there is no easy way to directly reference an assembly in the GAC if it’s not on the provided list. As for why you cannot select it when browsing to C:\Windows\Assembly... look at the folder again in the Windows shell... it’s not a traditional folder that you can so easily access as it is really an app known as the Assembly Cache Viewer and that provides a ve ...Show All
