• Windows Forms In a real bind...designer won't run w/ binding

  Here are the steps to reproduce my problem: 1. Create Tab1 2. Create Tab2 3. Place a bunch of controls 4. Add data bindings for two DataGridViews (one on Tab1, one on Tab2) == everything fine so far == 4. Add a new tab (Tab3 -- no controls) == still fine == 5. Move Tab3 to beginning (new order: Tab3, Tab1, Tab2) == stops working! == When I open the form, I get an error dialog . Then, when I hit OK, the form is broken. 6. Remove Tab3 == works fine again == 7. Add two new tabs 8. Move both tabs to the beginning (new order: Tab3, Tab4, Tab1, Tab2) == stops worki ...Show All

• SQL Server Exceedingly long update on large tables - why?

  We have a simple UPDATE query, joining two tables, that takes much longer than 10 hours to run, but if we break the table in six (10 million rows in each table), it takes only fifteen minutes to run each part. Why And how can we tell in advance whether a query will cross the threshold into l.o.n.g.r.u.n.n.i.n.g query Or, how can we prevent it The system is Windows XP Pro with 4GB RAM (/3GB switch), and SQL Server Standard 2005. Log files, swap files, dbf files are on separate drives. The system is dedicated to SQL Server. No other queries are running at the same time. The database is in Simple logging mode. Each table is a few GB with 60 ...Show All

• Visual C# Abstract classes and static methods

  Hello there! I was wondering why is not possible to define a static method into an abstract class, well... I was wondering that because I'm trying to force an user who inherits from this class to implement a static class and I just didn't find a way to do that... is there a way to do this Because there's a layer calling static methods and I don't want to change these methods to regular methods just because I'm not being able to solve this problem... Thanks Static methods can be defined in an abstract class. However, you cannot force a derived class to implement a static method. If you think about it, such a method would be ...Show All

• Visual FoxPro cannot open up a form-- BIG TROUBLE

  I have been working on this form for about two months adding new objects and manipulating databases. The last save I did was about 4 days ago. I have a few grids in it on different pages of pageframe and everything worked fine. I never added any columns to any grid at design time. At runtime VFP determines the column layout after a grid is given an alias as a record source. Today, just a few minutes ago I decided to add three columns to a grid which has always been empty at design time. After I did a save, I got an error message at runtime: Error loading file - record number 34: o_Grid2 <or one of its members>. Header Class: ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. rendering multiple video streams

  I'm developing an application which displays 4 (or even more, if possible) video streams simultaneously in real-time (30 fps per stream). I need a renderer that will take the raw YUV frames and display them to a Win32 window, scaling as required. Each stream is independent of the others, including running in separate threads. Currently, my app has an independent DirectDraw-based renderer for each stream (written by someone else), but performance degrades dramatically (much more than it should) as streams 2-4 start. I'd like to know how DirectX experts would approach this problem. Thanks for any advice you have, Scott ...Show All

• Windows Forms Dynamically adding CONTROLS in VC++

  Basically I'm creating an app where the entire thing is controlled by scripts. I want to be able to create a FORM on-the-fly, with controls added via scripting . how to do it Try to observe how Visual Studio designer generate codes when you design your form, this is exactly the same way you can generate a form and child controls on run-time. 1. Create an instance of an empty Form. 2. Set the properties for the Form. 3. Create an instance of a child control. 4. Set the properties for the child control. 5. Add the control to the Form using its Controls collection. 6. Repeat #3 to create more child controls. Regards, -chris ...Show All
