• Visual C# C# - Generics on this class type

  Hello, I am trying to instantiate a generic class, using the current class as a parameter. Normally you would do this like this (assuming a class MyClass): private Generic<MyClass> _g = new Generic<MyClass>(); And then i wrap this instance in a read-only property called MyGeneric: public MyGeneric<MyClass> MyGeneric { get { return _g; } } However, this is not really object oriented. Since any class derived from MyClass (MyDerivedClass) would have an instance typed on MyClass, not MyDerivedClass. i.e: MyDerivedClass.MyGeneric returns a Generic<MyClass>. So, how can i instantiate a Generic class using the current class-type as a parameter, in a truly object oriented (polymorphic) m ...Show All

• Windows Forms How do I disable the AddNewItem button on the bindingNavigator control ?

  I have a simple form with a DataGridView, a BindingNavigator and BindingSource allowing me to view the contents of a table called 'RUN'. I have included the DataSource in my project so a runTableAdapter and myDataSet.Run has been created automatically for me. The problem is that on this particular form I don't want the user to be able to add new items using the BindingNavigator control. I could just delete the 'AddNewItem' control from the navigator but for a consistent look and feel I would rather just disable it. I can disable it at design time which works to begin with. Then at run time, the user can select some 'filtering criteria' using other controls on the form and then press a button. I then fill the table using the following: ...Show All

• SQL Server DBMail - Attach CSV File - CSV file format NOT recognized when Excel tries to open it

  Afternoon. OK ... I have DBMail generating a CSV file from a query. ALL WORKS GREAT! I get the email and attachment. Issue is when I try to open the CSV, Excel comes back saying it does not recognize the file format. If I continue to open it, all of the column headers are in one cell as well as all the fields generated by the query are in the same row(s). I even see the comma "," seperater inbetween each column so I know the delimiter is being placed correctly. I am also able to save the attachment as a TXT file and then I am able to import it as a comma delimited file and it brings it in just fine. SO ... how do I correct the issue of the CSV not being in a format that Excel can open by default Thanks ALL! ...Show All

• Visual Basic Clock formatting

  I wrote a countdown timer program, but it seems that the clock does not show the 0 when it is less than 10, specially in the minutes and seconds. In the hour part, it's probably alright, but I'd like to show 0 in the minutes and second display. I use String .Format with this kind of formatting: "{0:d}:{1:d}:{2:d}" How do I show the zeroes in front You can use the .PadLeft method, or, for dates use the following formatting: Dim d As Date = Now Debug.WriteLine( String .Format( "{0:HH}:{0:mm}:{0:ss}" , d)) ...Show All

• Visual Studio 2008 (Pre-release) Impersonation problem?

  Hi, I seem to have discovered some rather strange behaviour inside a service when trying to impersonate the caller. I'm using WsHttp binding with default settings - no additional BindingConfiguration specified. My client side proxy is generated using the 'Add Service Reference' function from Visual Studio. The problem arises when the clientside proxy has its AllowedImpersonation property incorrectly set to the default 'Identify value', as in proxy.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal. TokenImpersonationLevel .Identification; On the server side, I'd expect the WindowsImpersonationContext impersonation = ServiceSecurityContext .Current.WindowsIdentity.Impersonate(); call ...Show All

• Windows Forms Transparent label Control in VB 2005

  I am trying VB 2005. The label control has no transparent (backstyle) option. The help says that this is so and to overcome it by setting the background color to transparent. I tried this but still get error that backcolor transparent is not supported. This is very annoying as I use transparent labels and text boxes all the time. Can anyone tell me what I am doing wrong or an alternative. Alot of the controls/components in Windows XP were released unfinished. Which may explain why alot of properties for certain controls/components act in awkard manners such as this. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Bug in BoundingFrustum.Contains()?

  If i write the following code: BoundingFrustum f = new BoundingFrustum(new Matrix(1, 2, 3, 4, 5, 6, 7, 8, 9, 8, 7, 6, 5, 4, 3, 2)); Vector3 vector = new Vector3(1,1,1); BoundingBox box = new BoundingBox(vector, vector); ContainmenType t; t = f.Contains(vector); Console.WriteLine(t); t = f.Contains(box); Console.WriteLine(t); I'd expect both to give the same answer. Either both are contained or both are disjoint. However the Frustum contains the point but the box is disjoint. What's going on It's not enough to test whether there is a single plane that excludes all the vertices. A box that's tilted just outside the corner of a frustum will then be considered "inside" even when it's "outside.&q ...Show All

• SQL Server Merge: Records associated by a JOIN Filter not being sent to a subscriber

  Hi, I have a merge (SQL 2005 Standard -> Express) topolgoy which is having problems  The main problem is that the join filters don't seem to work for one area and I am hoping someone can help me with some troubleshooting advice There are 140+ tables in the topology but the ones causing  particular  pain are a parent child relationship where the child is actually a bridge/linking table to another table. Therefore although it is a parent child in the replication filters it is the reverse. i.e. the child has the paramterised filter on it and the parent is one level down joined by it's id.  There are other tables joined to this parent table but it stays at three levels deep.  The @join_unique_k ...Show All
