• Visual C++ /clr Error

  // compile with: /clr #ifdef _MANAGED public ref class A { public: static void foobar(); // error C3280 }; #endif I compile the above in Visual Studio C++ 2005 with /clr and get error C3280. The documentation says if the /clr switch is set, it should compile as managed. error C3280: 'OSAPI::Net::Event::foobar' : a member-function of a managed type cannot be compiled as an unmanaged function So, why is a declaration in a compile unit that is built using managed code see this as compiling an unmanaged function Also, when the documentation says function, does the definition of function include method declarations I would say term "function" includes "member method declarations". ...Show All

• Windows Forms Editing tables without Primary Key

  Hello everyone. I am trying to work with a database in C# 2005 Express. One of the tables in that database doesn't have a Primary Key. However, it has a unique Foreign Key associated with each row. How can I select any particular row for editing on that table Its easy to select and edit tables which have a Primary Key by writing something like: dataset.TableNameRow row = dataset.TableName.FindBy(PrimaryKey); row.BeginEdit(); . . . row.EndEdit(); But how can I select and edit a row from a table which doesn't have a Primary Key Thanks in advance, Ashish i dont think you can actually access a row with no pk if u can't reference it.. if it is in a dgv maybe then but i havent tried it is good practice to keep an index or sum ...Show All

• Windows Forms Modifying BidingSource

  I wonder if I can modify the bindingsource to dispaly specific field from a table rather than displaying the whole table.  Here is what I am talking about.  I am using a commercial grid to display my data.

• Game Technologies: DirectX, XNA, XACT, etc. Custom soundtracks

  I've only had XNA Game Studio Express since yesterday, but I've been having a lot of fun with it. I've started working on a game which is coming along nicely, but one thing irks me - I can't figure out how to have music playing that stops when a user chooses a custom soundtrack instead. At the moment, when a user chooses their own track is starts playing fine, but the game soundtrack continues to play in the background. I'm sure I've missed something simple, but I can't for the life of me figure it out. Any hints would be much appreciated.

• Visual Studio 2008 (Pre-release) BAML->XAML

  Hi all! I know you don't like people using BAML, but I've got a bit of a problem: I have a program that I've written, and have lost the source code for. Luckily, I have the compiled executable. So, I have been able to extract the BAML file, but I'd really like it in XAML for easy editing. I know about loading BAML with Application.LoadCompenent, but that doesn't help when you need to 'decompile' BAML in to XAML. I've been told this was possible in earlier versions of WPF, but has been removed ever since Parser.LoadBaml was removed. Is there any way to retrieve the XAML source Karl After you have done Application.LoadCompenent to retrive an object instance from BAML, you should be able to use XamlW ...Show All

• Windows Forms How to use an IF statement to filter values in a DataSet column?

  Hi, I'm new to C# and I'm currently stuck at using an IF statement to filter certain values within a dataset. A DataView isn't an option since I'm trying to loop through the entire record set. Specifically, I'm trying see if the object "Type" equals to "Outage" or "TR Outage". I'm getting compile time errors saying that it cannot implicitly convert object to bool and another one that cannot use operand ||. Here's the code I have (problem highlight in bold).
