View 7 RepliesI am using Visual Basic.net 2010 to try to develop a simple VB application to control a data projector using RS232.So far, I have programmed the 'power on' button to open the serial port and send the power on command.The port opens successfully, but the projector does not receive the command properly, so it never powers on the projector.The RS232 command for power on is: BE EF 03 06 00 BA D2 01 00 00 60 01 00
My code for sending the command is: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

View 5 RepliesI have an application that monitors a set of opc boolean tags.When a tag changes from false to true (triggered), the application is supposed to query the database for data recording during a specific time period.I had the app done or so i thought until i realized that the background worker that i dimension to do the query is not firing the runworker completed event.at the start of the app, I create a new class for each trigger config in an xml file. Each trigger class has its own opc monitor and handle specific for that one boolean tag.If a tag changes to true a NEW instance of the query class is created.A new background worker instance is dimensioned to do the actual work.(this because there is a pre trigger query and a post trigger query which could be up to 24 hrs after the event has been "triggered" to true and the bg worker will wait until the required amount of time has completed before doing the post query).When the bg worker has completed, it should dispose of itself and all its managed resources.
The very first tag that changes to true will function as expected but when it is complete the RunWorkerCompleted will not fire. Everyone there after will operate as expected but not the very first one.I couldnt figure out why so I started commenting out some code.If I remove the line to create a new oracle connection, it works.
