• Game Technologies: DirectX, XNA, XACT, etc. Rants on XNA 1.0

  This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the contents are only built before the program runs. The helper functions wrapping D3DX can only be used with types in the content pipeline. I have to utilize the full content pipeline just for generating something dynamically, of course with significant performance cost. Or I have to write those D3DX utilities my self. Currently I don't have a good id ...Show All

• Visual C# Passing properties as delegates

  Let's say I have the following: class Foo { private int myInt; public void SetInt(int i){myInt = i;} } And then somewhere else, I have this: delegate void MyDelegate(int); // Define a delegate that matches the signature of the Foo.SetInt function class Bar{ void DoStuff(MyDelegate someDelegate){ .... } // A function taking the delegate as an argument } Now I can easily pass SetInt as a delegate to the DoStuff function, no problem there. But what if I'd used a set property instead of the SetInt function, like so class Foo { private int myInt; public int MyInt{ set {myInt = value;} } } Is there any way I can then pass the MyInt property as a delegate to another function I suppose I could do it by wrapping it in an ...Show All

• Windows Forms Problems with "Show Dialog" and Large amounts of data

  I have an inventory lookup form, called from many different user controls, that could easily be loaded with large amounts of data (150000+rows). My problem is that with only 22000 test records it takes about 35 seconds to load. This would be acceptable if I could load it up the first time and then simply hide it. The problem is that the ".showdialog " method of the form, while it works and allows me to pass the selected ID to the calling form, brings up a new instance every time causing the delay reloading every time. In VB6 you could hide the form then show it again and pass a global variable containing the selected ID from one form to another. In VB.net 2005 the Only way to pass the variable from the one form to the other, ...Show All

• Visual Basic null reference in passing array between procedures

• SQL Server AS 400 data being interpreted as unicode strings (DT_WSTR) datatype

  I am building a data warehouse. Some of the data comes from an AS 400 EPR system. I used the OLEDB connector when first pulling the data into SQL Server doing simple import data from table option. That worked great for getting the initial data load into SQL Server and creating the base SQL Server tables although it was excruciatingly slow (that was probably due to the transport from the AS 400). Now, I need to get new records that are added to the AS400 side of things on a daily basis. For that, I was trying to use the OLEDB AS400 connector. However, I found that the OLEDB connector wouldn't work when I was trying to specify an SQL Statement for what to get; i.e., a simple query like Select * from TWLDAT.STKT where BYSDAT >= '2005-01 ...Show All

• .NET Development GetHashCode and Equals once again

  I do not see how GetHashCode() and Equals() can ever successfully be implemented given the guidelines. I am assuming that one of the guidelines, apart from the well-known one of two objects being equal ( Equals() ) returning the same hash code ( GetHashCode() ), is that GetHashCode can not change during the lifetime of an object. Given this assumption it appears to me that GetHashCode must either be implemented on a totally immutable class, or that it must only use immutable data members of a class. Since this is the case, the Equals() function must also depend on either a totally immutable class or only use immutable data members of a class. To me this need to rely only on immutable data in a class defeats the entire purpose of object eq ...Show All

• Visual C++ VC++ won't run from source control: "The system cannot execute the specified program"

  Hi, I've installed VS 2005 C++ Express into source control and it won't work. I've wasted the better part of a day so far trying to get it to work. The error message I get when trying to run something as simple as lib.exe is: "The system cannot execute the specified program."

• SQL Server How to process partition as processReaggregate in SSAS 2005

  processReaggregate in MSAS 2000 only rebuild map, index and aggregation for a partition. It is fast to process a partition after redesign the aggregates. Could anyone tell me how to process a partition as processReaggregate in SSAS 2005 ProcessDefault Thanks. It is one of the cases where the answer is really short :) In AS2005 you use ProcessIndex command to do exactly that: Rebuild aggregations and indexes for partition.
