• Visual Basic DataGrid View Hover Picture

  Using VS 2005, I am writing a Windows control object which will display a grid of person records. I want it so when the user hovers their mouse over the picture cell, a popup image appears which follows the mouse cursor. I can get the image popping up and actually display on the screen, the only problem is I know the absolute position of the mouse but not where the mouse is in relation to the form. When I set the location for the image box, I n ...Show All

• Visual Basic Visual Basic Performance for 3 Million record/rows

  I have a Visual Basic 2005 .Net program that I written that read a 2000 and 2005 database. I was very surprise and shocked when it took three days to process only 600,000 rows of a 3 million row result. Because of the time it took to only process 600,000 rows I canceled the batch job and did everything in SQL using Query Analyzer. I was able to process the same volume in only 45 minutes. I was greatly disappointed in the results. T ...Show All

• SQL Server ODBC & Multi-threading

  I'm working on a C# (2005) app that requires shooting a large number of queries via Odbc, wait until the last one is done and then compute an overall result. Since the queries are not interdependent, I would like to get them to run concurrently on multiple threads. I did manage to get several queries run on different threads but the response time for the same query varies dramatically when another query is running concurently (even on a di ...Show All

• SQL Server ForceExecutionResult is ignored by parent

  1 Add a Sequence Container. 2 Add a Script Task to the contianer, and set the script to fail, Dts.TaskResult = Dts.Results.Failure 3 Set the ForceExecutionResult on the Script to Success. 4 Execute the package. The container fails, so it detects the Dts.Results.Failure, and ignores ForceExecutionResult. The task itself is Green, so that indicates success. I think this is wrong, as ForceExecutionResult should be observed by both the task and pare ...Show All
