• Visual C# Design Issue

  I have the following forms and the MDIparent can open 3 different types of child forms. MDImain form.    ChildForm1    ChildForm2    ChildForm3 So the MDI has to transfer fileNew() or fileOpen() to each childform since the child knows best how to handle this. Should I use a property to trigger this event from the MDi fileNew_click event Something like    ChildForm1 childform = new ChildForm1;     childform.MdiParent = this ;    childform.setNewFlag(true);  <<===== trigger event in child which can invoke       &nb ...Show All

• Visual Studio Express Editions Converting a System.Object to a byte[] and vice versa?

  Is it possible to convert a System.Object to a byte[] and vice versa The reason I ask is I'm using the encryption built into the framework and need to encrypt some objects after I put them into an ArrayList. If this isn't possible, how could you convert a struct to a byte[] and vice versa I found the following code posted by a MS VIP in another forum but it doesn't work with my structs (I'm thinking because I have strings in them, which means I can't use the Bits.Converter class) static unsafe byte[] NoteDataToBytes(MyStruct nd) { byte[] NoteDataInBytes = new byte[sizeof(MyStruct)]; fixed (byte* pNoteDataIn ...Show All

• Visual Studio 2008 (Pre-release) SSPI fails without userPrincipalName, why?

  I'm using a netTcpBinding with a self-hosted service running as my own user, with a client of ASP.NET hosted by IIS running as Network Service on another machine. I'm a bit confused on the service/client identity and how it relates to authentication. I find that if I don't specify anything in the <identity> for my client <endpoint> things fail: Error: System.ServiceModel.Security.SecurityNegotiationException: A call to SSPI failed, see inner exception. ---> System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The target principal n ...Show All

• .NET Development DeriveParameters with Provider-Independent Data Access

  Well the Provider-Independent Data Access is quite good in ADO .NET 2.0 My only problem with it and what makes it somehow useless is that DbCommandBuilder does not have an implementation for DeriveParameters... Now My code goes: ------------- DbProviderFactory DbProvider = DbProviderFactories .GetFactory( "System.Data.SqlClient" ); DbConnection dbConnectionObj = DbProvider.CreateConnection(); dbConnectionObj.ConnectionString = ConnectionString; DbCommand dbCommandObj = DbProvider.CreateCommand(); dbCommandObj.Connection = dbConnectionObj; dbCommandObj.CommandText = storedProcedureName; dbCommandOb ...Show All

• Visual C++ is there a better way ?

  I'm new to C++.NET & for the 2 or 3 applications I've written that have used .lib files, I explicitly add them into Linker >> Input>> Additional Dependencies & type in the path for my computer. Thus works fine, but every time I transfer the application to another computer & I need to open up the project & chnage the path. Is there a better way to include the lib files regards, ak Linker - Input - Additional Dependencies are stored in the project file (.vcproj file).  You don't need to open the project every time, it will be saved in the project.  As long as ...Show All

When the speaker was asked about private and protected members, he said they had something for him, but he never actually said what it was. How is this possible I don't want to have to make methods public and wrap a property around every field just for testing.

• Visual Basic Visual Basic 2005 Express Ed. BETA 2

  Hello. I was wondering if it's possible to get Visual Basic 2005 Express BETA 2 on CD without having to have a Credit Card in Australia. I have tried the manual and automatic downloads and they don't work for me at all, both at home (not connected to internet) and at work. (I couldn't use the automatic download at work due to me not having admin privleges) Thanks. Hello again I've just downloaded it. I had to split it into 5 pieces and take it home like that... It should still work... I hope... I've only got 2 pieces left! Yay! (As long as they don't reset the server) Once I've got all the pieces I'll burn it to one of my brand ne ...Show All
