• Visual Basic upgraded os, now can not find .dll

  I work for a company who just recently updated their OS from Windows 95/ 98 to xp. The most important program they run was custom made and worked fine in the older OS. When it is run on XP it has an error before it even opens saying "Run-time error: Dxinit.dll not found" . I have talked to the original programmer who said that .dll was custom made and needed to be upgraded already to work on 98. My question is this, how can I get the new OS to see this .dll and run the program I have the VB project files and all the info for installing and compiling.

• Game Technologies: DirectX, XNA, XACT, etc. how to find elapsed time?

  Is there a Windows and Xbox 360 way that I can get the elapsed time between two events For instance, I want to find the ammountt of time the user waited between two mouse clicks. It could be 200 ms, or it could be 5620 ms. I don't need the code for mouse clicks, etc. I just need to know how to get the total elapsed time in milliseconds since the last time I asked for it. Much like getTickCount in the win32 api. Thanks! You could save the gameTime.TotalGameTime.TotalMilliseconds value at the first click, and then when the user clicks a second time, subtract the total milliseconds current from the saved saved value. if(firstClick) baseTime = gameTime.TotalGameTime.TotalMilliseconds; else if(sec ...Show All

• .NET Development passing dbnull to splserver express

  I have an application i'm writing connecting to sql server express. there is a field call PayDate which is a text field and it passes the date to a coloumn in splserver which is a "date" type and allow nulls is checked. I can add and update the dates changed with no problem, but what I want to do is when the date on the textbox form is removed, I want to pass a "null" back to the PayDate column in sqlserver so it shows as "NULL" . When I used "mySQL", I had no problem passing a null back, but with sqlserver I can't seem to get this to work.

• Game Technologies: DirectX, XNA, XACT, etc. Starting 3D from 2D

  I come from a 2D background and figure that XNA is a perfect chance to start making some 3D programs, one problem: the math and terms involved are becoming too much for me. I'm looking for a resource to simplifiy the 3D process, I went through the nice video tutorials and got my ships moving and rotating; even got them rotating/moving on all three axis (axi ), albeit with some weird behavior. Terrain terrorifies me, I have no idea on any of it. I'm looking more so for explanation rather then code, I followed reimer's tutorials but I found them incredibly confusing; they seem more angled towards someone to play with the code rather then learn from the explanations. Anyway, please if you have any resources share'em with me because I'm con ...Show All

• SQL Server .NET Custom UDF - "Internal error: An unexpected exception occured."

  Hi! I have developed some .NET UDF for MSAS2005. I compiled it, added assembly to database and tested it - it works. But works only on my test seerver. On life server I've got this message: "Internal error: An unexpected exception occured." Assembly is registered as unrestricted. I've maid simple test function in own assembly file, which just gives back 1. It also works on test- and does not work on life server. Customer will kill me :-( .... P.S.

• .NET Development Neither XmlReader nor XmlTextReader are able to process my XML file

  Hi, I am not able to use the XmlTextReader class in C#, as it is not able to read DTD entity codes, and I can't use the XmlReader because it returns bogus AttributeCount/HasAttributes values. In other words, I'm stuck. I started by using the XmlTextReader, which works nicely until I get to XML that uses DTD entity codes. I needed to use the XmlReader.Create() method and pass an XmlReaderSettings object into the constructor - with ProhibitDtd set to false. This worked, but now I get plainly incorrect results for the HasAttributes and AttributeCount method/properties. AttributeCount is returning 1 when reading the following element: "<gloss>readability</gloss>". Not only that, but the 'HasAttributes ' property returns true while ...Show All

• Visual Studio 2008 (Pre-release) Func definition syntax to change?

  LINQ is pretty cool but when I see this: delegate TR Func<TR>(); delegate TR Func<T0, TR>(T0 a0); delegate TR Func<T0, T1, TR>(T0 a0, T1 a1); delegate TR Func<T0, T1, T2, TR>(T0 a0, T1 a1, T2 a2); delegate TR Func<T0, T1, T2, T3, TR>(T0 a0, T1 a1, T2 a2, T3 a3); It stands out pretty quickly that a slightly different language structure is needed here... this brute-force approach is trouble. What if I need a predicate with 13 parameters I've lost the convenience this syntax intends. One obvious alternative would have been the pre-existing EventHandler model, by using one EventArgs object the author overrides - in this case a QueryArgs object: delegate TR Func<TArgs, TR>(TArgs args) where TArgs : QueryArgs; ...Show All
