• SQL Server Can I Use Non-empty Behavior for These Calculated Members?

  I still find myself extremely confused about using the non-empty behavior for calculated members. We have a series of calculated members that we refer to as "Velocity", such as "Velocity Sales". The basic definition for these velocity measures is to get the total from the previous 63 business days and then annualize that total (i.e. multiply by 4), with the 63rd business day belonging to the previous month. For example, Velocity Sales for any day in September 2006 would be totaling the sales $ for the business days in the range of 06/05/2006 through 08/31/2006, and then multiplying it by 4. Perhaps not surprisingly, these measures result in extremely poor performance. Since I'm confused on the non-empty behavior, this p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotate to match a heading

  OK, sorry if this is already somewhere.... I couldn't find it when I did a search. I'm working on a 2D project where I have images moving around the screen. They have a 'heading' vector that is sort of generated randomly. I'm trying to calculate an angle of rotation based on the dot product between the heading vector and a 'straight' vector of (1.0f, 0.0f) ... I'm using this because the original image for rotation is facing to the left. (its actually a left arrow --> ) It seems like its sort of working, but not quite right. Sometimes they aren't oriented correctly, and when I put in a negative value for the heading like (0.0f, -1.0f) it rotates as if the heading were (0.0f, 1.0f)..... meaning the sign was lost somewhere in the dot prod ...Show All

• Visual C++ Can't get Csv format for clipboad to work with unicode

  I have been struggling with writting a comma seperated string to the clipboard with the intention of pasting the string into excel. The code below works fine for all three character sets (ANSI, MBCS, and UNICODE) when using appropriate standard formats CF_TEXT or CF_UNICODETEXT. When I add the Csv format everything works ok for ANSI and MBCS but does not distribute the values seperated by the commas in the text strings into individual cells in UNICODE. In fact, when I paste special and select Csv, all I get with UNICODE is the first value in the first cell as opposed to 1 in first cell, 2 in second cell, 3 in third cell, and 4 in forth cell. I get the Csv in seperate cell with my project set to ANSI or MBCS. What am I doing wrong I use ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX SDK Slowdown

  Hi folks. I used to use Blitz3D to create 3D games because it was so easy to rapidly develop a game whilst avoiding all the general complications involved. The obvious downside with Blitz was that it wasnt an object orientated language. It seems that Game Studio Express has been written for the same purpose - to make Game programming easy and rapid. So I'm interested in using Game Studio Express as I am familiar with C# and it seems like it could be the next logical step (although I see I'm going to have to wait until the content pipeline arrives before doing any 3D). I have one concern though: Does installing the DirectX SDK slow down games and/or your system in general I remember installing the DX7 SDK years ago and since it enabl ...Show All

• Visual Basic Newbe - needs help with configuration

  I have installed Visual Studio with my SQL server. I don't know why but when I create a new project the only templates I get are Business Intelligence Projects, I want the Microsoft Application template.

My Visual Studio Express will not connect to the SQL server saying it is not configured for remote access yet I know it is as the Visual Studio connects fine.

• Windows Forms DataGridView, KeyDown Event

  Hi, It seems as the KeyDown event only fires when a column, row, or a combination is highlighted. This does not include the case when a cell edit session is in progress, in which the event does not fire. Any event to capture the keyboard entries while the cell edit mode is on going. Regards, Reza Bemanian Goran, I read through the thread you generated earlier. Strangely enough I use the EditingControlShowing event to update a DataGridViewTextBoxEditingControl object, which provides the metrics to manipulate the editing text. In this case, I am using the Text, SelectionStart, and the SelectionLength properties. The problem is the Text properly always shows the cell content, though capturing the re ...Show All
