• Visual Studio Tools for Office Add/Remove Worksheet in VSTO Workbook

  I created various worksheet inside a VSTO workbook, but now, I can't remove my testing worksheet and add blank new worksheet. 1. I can't select Delete in solution explorer when right-clicking on the worksheet item. 2. Even I remove worksheet in Designer pane (right click the tab at the bottom of Excel workbook and selete Delete), rebuild the VSTO project and then the deleted worksheets are all still here.

• Game Technologies: DirectX, XNA, XACT, etc. PointSprites and Alphablending?

  I followed Riemers tutorial on point sprites and got it almost working. This is how it looks like: http://www.karlfredberg.se/cgtalk/pointSprites.jpg I am also using the sample from the Animation Component and this is where I think the problem lies. The Zdepth sorting works fine with ordinary objects but the objects from the sample doesn't work. I guess there is something with the World Matrix that screws things up. I have no idea how to fix it. Indeed, this problem has to do with the Z ordering of your scene. I bet you're first drawing the bullets, and next the scene behind it. At the moment you're drawing the bullets, the bullets are blended with the color behind them: plain blue. Next, when you d ...Show All

• Smart Device Development Improving the performance of the application?

  Hi, I have a form (Form2) with ImageList. When I try to show form2 with ImageList takes 6 to 8 seconds time which may make the user impatient and irritative. When I run with out ImageList takes 2 sec time. Actuallly I am taking the images from the imagelist and showing on panel. With out imagelist If I try to take images directly to pictureboxes it take more than 8 seconds time. Can any one guide me how reduce the time from form to another form.

• Visual Studio Express Editions Allowing the user of your application to import their own files

  Ok, this is something totally new to me. I've not delved into this with VB at all. Here's a summary of what I want to do. I want to create a flash card application for a teacher. The program itself simply displays information and the student must respond to the information. To check their answer, the "reveal" the back of the card. Similar in concept to normal flash cards. However, I want this application to be as flexible as possible. I want the teacher to be able to IMPORT an ASCII text file from within my application. So, my question is what's considered "best practice" when programming something like this Additionally, what would you suggest for references in finding sample code to experiment with and ...Show All

• .NET Development Error "ExecuteScalar requires an open and available connection..."

  H all, I have an application that retrieves data from a local SQL2005 (Standard edition) database frequently (e.g. more than 10 times/second normally). It usually works fine. However, if the program was paused for a while (e.g. for a few hours) by a pop-up error message box or an Sleep() statement, it generates the following error message when its data processing resumes: " ExecuteScalar requires an open and available connection. The connection's current state is closed ." The application is coded with C# using ADO.Net. The connection is OleDbConnection. It seems there is some timeout process that I do not know. Could anyone offer any hint Thanks, hz Thank you all for the information! Firstly, let ...Show All

• Software Development for Windows Vista EventDeliveryFailedException

  Hello. I already asked something similar to this in at least one other thread. And many other Threads ask about this problem This time I'll post real code, so there are no doubts. In the highlighted line the execution stops saying there is an EventDeliveryFailedException. I know for sure the service is registered in an ExternalDataExchangeService. And I'm sure the HandleExternalEventActivity is listening to the right event form the right interface. And I know through Tracking that the HEEA is in execution.

• SQL Server Trigger not executing

  I will try to keep this as simple as possible and make a long story short. The college I work for has bought a third party package to basically run the operations of the school. There is a component for registration, admissions, billing, etc. It also has a web component so students can access their school information from anywhere. The backend for all of this is SQL Server. To make things easy, the vendor has provided us with the steps to bulk load users, via DTS, into the system and create their accounts for the web portion. The way this works is as follows: I create a CSV file which I then load via DTS into their "Bulk Load" table. This table has an "on insert" trigger that fires off when the load happens on the &q ...Show All

• SQL Server How to find the dependency object of a particular table

  Hi all, I m using SQL Server 2000. I want to know the Dependencies of a particular table in my database.
