• Visual FoxPro Why my VFP exe file cannot be launched?

  I complied my program under VFP6 into an exe file in the program folder. But it cannot be launched. I believe there is nothing wrong with the code, because I just made a minor change. The funny thing is that if I copied the file to other folders on the same drive, it works! And even more wear is that some old version VFP exe files could not be launched from within that program folder, either. I have to copy them out to test. It only happens to VFP exe files. Other exe files are OK. It did the same with VFP9. Any idea what could be the problem I assume its your application (EXE) not VFP.EXE which u have complied is not working from a folder, but if u copy it to another folde ...Show All

• SQL Server Inserted and Deleted tables

  Hi: Can any of the experts please confirm the fact that Inserted and deleted tables in SQL Server 2005 are stored in tempdb . If so, how can I query them in tempdb ( A code snippet would be useful). Thanks AK The article describes how sqlserver physically create/maintain the inserted/deleted table. For a very long time now, tempdb has always been used as the workspace for sqlserver. It uses tempdb to hold the paged data that can't fit in the allowable memory - @table variable is the best example of this. So, in the new sql2k5, instead of scanning the log to materialize the inserted/deleted table, it goes ahead and store a copy of updated data in tempdb. This will make the materialization faste ...Show All

• Windows Forms Update custom control at design time when property changed

  Hi guys, I created a custom control SListView extending ListView. I define the SListView to hold a collection of a simple class type, which has two fields: name and id. Name should be displayed in the SListView control. Everything works fine except after I added a collection of names, the SListView control does not update its content at the design time. It will only display the names at runtime. I searched for answer, it may related to ControlDesigner.OnComponentChanged method, but I can't find examples on how to use it. Any suggestion Thank you!

• SQL Server SQLEXPR_ADV.EXE does not detect WinXP SP1

  Running SQLEXPR_ADV.EXE against Windows XP SP0 causes the setup to exit gracefully with a message indicating the the right service pack is not installed. However, running SQLEXPR_ADV.EXE against Windows XP SP1 does not exit and continues to install. Then, when you try to run a script against the installation, you get the message: [Microsoft][ODBC SQL Server Driver][DBMSLPCN][SQL Server does not exist or access denied]. This will become very problematic when installing SQL Server Express as the database for small installations. The setup really needs to be updated to look for all the system requirements that it can detect. Evidently it can detect the Service Packs. The Wise Installer is not able to script that requirements unles ...Show All

• Visual Studio 2008 (Pre-release) Guidance for IErrorHandler

  Hi, I'm looking for some guidance on how I should use the IErrorHandler. I have it configured, and running, but I'm really not sure how to go about getting it to the "right" things. Additionaly, I'm supposed to make it interact with the exception policies (ExceptionPolicy) of EntLib. Thanks Thanks Justice, I was able to get the specific FaultException<T> returned to the client To do so, I had to check the type of the exception (MissingMemberException) passed to IErrorHandler.ProvideFault, then create the correct FaultException<MissingMemberFault>(new MissingMemberFault(exception.Message) To avoid the repetitive code for each type, I've used a dictionary to ma ...Show All

• Windows Forms What is BindingSource?

  I know it is a broker between your datasource and your databound controls, provides a level of indirection between them and it is introduced in Framework 2.0 but what does Binding Source do What additional capability it provides compare to Currency Manager, Binding Context and Binding manager base One thing that a BindingSource does is it allows you to connect multiple DataGridView tables to a single data source. (Something not previously allowed before) This lets you do several things: Bind a parent table and display (in the second datagrid) the child table bound to the parent. Bind several datagrids to a single data source. You can display available records in one datagrid, display ...Show All

• Visual Studio Team System MS Project 2003 Dates not retrieved from TFS

  When retrieving work items using MS Project, dates are not retrieved correctly. The dates can be viewed using Excel or Team Explorer. Any ideas Alyaru, Thanks for the additional information. Regarding other fields being refreshed even though attribute PublishOnly="true" is a bug. I will log a bug regarding this issue. Regarding the old issue(Dates not getting refreshed) MS Project does scheduling on all the tasks automatically based on certain fields including "Remaining Work" and "Completed Work".This is the reason we made the date fields "Publish only" in MS Project and not editable outside MS Project. So that users edit these fields in MS Project and all the scheduling fiel ...Show All

• Silverlight (formerly WPF/E) web services

  Hello, am I correct to understand that there is no .NET framework integration yet I am wondering what support for calling web services there will be in v1 release. The usage I am thinking for WPF/E is to have XAML+C# as a complete front-end, using no javascript, and talking to backend web services. Does this sound like a reasonable usage that will be well-supported and is a goal for the WPF/E initiative To me it does not look like the December CTP supports this. Thanks, Brad Williams Going forward we plan to support the scenario you articulate using a slimmed down .NET Framework version. This CTP does not have that funcionality. Nevertheless, you can use ASP.NET and ASP.NET AJAX in conjunction wit ...Show All

• Commerce Server OrderGroup class questions

  I have a few questions about the OrderGroup classes (ie. Basket/PurchaseOrder) that I was hoping I could get some clarity about: 1.) When I add a variant product to my basket, and I bind the LineItems collection of the basket or PurchaseOrder to my grid, the DisplayName associated is the Variant's DisplayName, which could be something like "Small, Green" where the product family displayname would be "Polo T-Shirt". How can I make the grid always display the product family's name rather than the Variant Displayname 2.) Can one run Pipeline components on Purchase Orders or only on Baskets I ask this because we have requirements that will allow an order processor to add items/modify items/qty/prices... etc.. after an ...Show All
