• .NET Development Visual Studio VWD generates incorrect SQL for Access database with autonumber key field

  While trying to demonstate the 'code free' benefits of VS2005 to students I noticed that the SQL generated for a simple Access table with an autonumber for its key field does not handle INSERT properly. It insists on including the Autonumber field in the SQL, despite only providing TextBoxes for the non-key fields. See the following: < asp : AccessDataSource ID ="AccessDataSource2" runat ="server" DataFile ="~/App_Data/names.mdb" DeleteCommand ="DELETE FROM [tblNames] WHERE [ID] = " InsertCommand ="INSERT INTO [tblNames] ([ID], [Name]) VALUES ( , )" SelectCommand ="SELECT * FROM [tblNames]" UpdateCommand ="UPDATE [tblNames] SET ...Show All

  Hi, I need to copy folder. In vb6 I had fso.

• Visual Studio Team System Work item assignment

  Can two people work on the same work item simultaneously Multiple users can open (and read) workitems simultaneously. If you are using the Visual Studio UI, if two users edit the same workitem, the first person to save the workitem has his changes committed. The second person will not be allowed to save and overwrite the first persons' changes - he will have to get the latest version of his workitem and make his changes again. If you are editing the workitem using Excel, Excel integration supports a feature to merge changes from the two users, so you may be able to write changes to the workitem depending on the kind of changes yo ...Show All

• Visual Studio Tools for Office Drag & Drop + VBA Marco Question

  Dears, I have 2 questions: 1. I'd create a DataGridView inside a User Control (ActionPane) in my VSTO2005 project, and I'd like to know is it possible to allow users to "drag and drop" a DataGridViewRow item, that's row(s) of data, from ActionPane to Excel worksheet directly I can't find any DragEnter event handler for the worksheet object. 2. I want to display a dialog box asking user to select a location of a dynamic ObjectList, that mean, I'll create a ObjectList on the fly and let the users select a destination. I tried the Globals.ThisWorkbook.ThisApplication.InputBox with option 8 (Range) but it's just a modal dialog, I even c ...Show All

• Visual C# Thread Safe Access to DateTime

  Hello all ... I'm working on a class to return the current date. It is a bit more complex than the following code due to managing cultures, but below is the basic idea. My question is: how can I ensure the execution of the get property is thread-safe, without single-threading my application My understanding from the doc that is that I need to be thread safe when using DateTime. I was thinking that lock would be too restrictive and with a lot of calls to this class would almost single-thread my application. Would a Read Write Lock be appropriate here Some other approach Thanks so much for your suggestions! Doug ...Show All

  As Anders pointed out in his Channel9 demo, Extension Methods in C# 3.0 really make Linq possible.

• Visual C++ Changed the COM signatures....using ildasm.....

  Hi, I have a .exe COM which I used in .NET but some signatures got changed....so I opened it with ildasm and changed the signatures so that it should return something from the function....This is the error I'm getting now.... The runtime has encountered a fatal error. The address of the error was at 0x79e8aff6, on thread 0xb4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack. Any Ideas.... Thanks, Harsimrat ...Show All
