• .NET Development Delayed Datareader column error

  In a live application which i created, i noticed that after a day or two, i get a datareader error, specifically the error which returns a column name as it's message. i.e if i had written reader["col_name"] i get col_name as the error message. The problem is that i read 5 column names in a single read, and the messages vary, it not always the same column name. However, whenever i restart the server, the problem goes away for another day or two. Recently i increased my max pool size because i was having pooling issues, this had an effect on the datareader error in that it now occurs every 2-3 hours instead of the 1-2 days. pls i need help on this one Thanks The error is saying that the ...Show All

• Visual Basic Installing VS 2005 Broke ActiveX in VB6 and Access - Need Help

  I have a development machine at work that has Access 2000 and VB6 on it with working projects. I have installed VS 2005 as I am training in that language now as well. My problem is that I have functioning code in Access and VB6 that no longer works because of the licensing errors for ActiveX objects. The only KB article I found that remotely refers to this issue asks that you import the VB6Controls.reg file on VS 2005 Pro CD #2. I went to do it and the .reg file does not exist on any of the VS CD's and I'm not even sure if this is the fix I want to use. I need the code in VB6 and Access to continue working but I also want to develop new things in VS 2005. Help Thanks! Can you please tell me which co ...Show All

• Software Development for Windows Vista how to customize icons shown in the designer

  Hi, does someone know, how I can replace the images shown for the root activity and for the last activity in the designer with my own images I mean the white arrow within the green circle on top of the designer surface and the white circle within the red rectangle at the bottom of the designer surface. All activities are shown inbetween these symbols. Regards, Mario Solved this myself. I found that the workflow itself is an activity by studying the FlowChart example provided at this site.

• Game Technologies: DirectX, XNA, XACT, etc. Managed DirectX performance

  Hi, I can't get DirectX to go faster enough in 2D environment. Wasn't expecting to hit a road block so soon. Any solutions to improve 2D performance. VB.NET\Window\Fullscreen\ VSync makes your application to synchronize with the monitor vertical refresh (if it’s faster, waits for the monitor). It allows to get rid of small image artifacts, but it will make your application to never go over your monitor’s refresh rate. That can be definetly the reason... If not, something is slowing down your code. Is your scene very complex ...Show All

• Windows Forms Need to change the System Date Format through ASP

Please help me on this. Thanks in advance. The DateTime.ToString() ...Show All

• Visual C++ const_cast and mutable

  Hi All, Anybody can give some realworld scenarios on using const_cast and mutable objects I think the use of mutable is justified when maintaining state is not visible externally.  Scenarios: 1. As Jonathan said, a counter on number of accesses.   (Note that this doesn't include the scenario in which you count object instances--thats' where you would use a private static member.) 2. More oftenly, caching.  You want your "read-only methods" to perform faster.  Caching results as a private mutable data member is a good way to accomplish this.  Conventionally, you should expect that a mutable data member's value would never change the result of calling a const member function: i.e. you must maintain t ...Show All
