I am working on a program to turn on devices at times of day and days of week. I am designing it for 15 devices and each device has a file. The problem I have is monitoring all 15 files. I can monitor each one and it works for that device, but only the device file I have called. I used data binding to create the files and can display the files one at a time, but I need to monitor the info on all 15 files actively.

The code below works and the event fires but nay code I insert in the OnChanged events gets this error:Error 7 Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
The error message makes no sense to me. I just want to call a SUB() on the same form or make a call to me WP class as shown. How do I do that?

I am trying to use the filesystem watcher to monitor a folder on a ftp site for files added. Does anyone know how to do this? I have even read that the filesystem watcher was not meant for ftp's but rather local monitoring, which doesn't make sense to me.
View 1 RepliesI'm writing a program which has to perform several operations on data exported from a CAD software.The amount of data to be processed is huge and even by simplifying the program at maximum it will still take about 10-15 minutes for average models.
The operations are performed on an array from the first to the last element. Let's say for a list of 10 elements (as example) that I start from element 1 and I finish when element 10 has been computed. I thus thought that since I'm working on a 8 processor machine would be convenient to make use of multi-threading. My idea is, for the case of 10 elements, to make thread1 working from 1 to 5 and make thread2 working from 6 to 10.I already wrote a working code for a 2 thread process which is working, but I want to extend the number of threads and eventually decide in function of the threads available. The basic structure is given below:

Can I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..

actually i have to develop a project to monitor EDI/Edifact data that are send between different EPR systems.Different erp systems means also different database systems. So i have to develop an app to monitor up to 5 tables.These tables can be stored in SQL Server, Oracle, MySQL or DB2. What kind of data access do i have to use ? ODBC ? ADO.NET ?? I actually don't have an idea how to handle this.In the app (i have to write) there should be something like a "DB Configuration for EDI" and there i want to configure if it is SQL, MySQL or what ever that i have to access.In the different Databases all the tables have the same name (means in SQL there is a table called Actlog and in Mysql also a table called Actlog)How can i write my app that it is DB independent ??

I have a piece of hardware that is controlled via USB.There are 8 LEDs on the output byte. One LED per bit.I like to toggle the outputs based on selection of checkboxes and given frequency entered in TextBox.I inserted 8 checkboxes to allow me to select the desired LEDs to be on.I select the checkboxes to select the required LEDs.The checkbox gives me the byte value. XORing the byte value with 255I can see them toggling very fast. I have a while loop to blink forever until I click on stop button.The stop makes the seq=false and this should stop the blinking but it keeps going.How can I insert desired delay of flashing frequency in my output routine?How can I stop on demand to change pattern without exiting the program.

View 9 RepliesI'm trying to make a simple program that keeps track of a list of phone directories. It offers the option of adding new names to the directory and deleting names already stored.I want the program to display a small unobtrusive message when a name is added or removed.For example, a label that shows "James Potter added to directory..."and then disappears after a few secondsGoing through th file mentions the timer but it seems like an awfully long winded way involving a new control and a new subroutine for every single timed event. I was wondering if there's an easier way, perhaps a single command like:
