I have written a program that will gather data from several different COM ports and reformat the data before sending it to a web site. This program is intended to run 24/7, but only send the information at user specified intervals. I have the routines to gahter data, but I only need it to perform this task at the specified time (5 minutes to each hour). At startup the dialog minimizes to the system tray. I would like a balloon message notifiy anyone watching that the data is about to be sent, and allow them to add additional comments if they choose (by clicking on the balloon). The system tray icon has several context menu items that the user may need. Is this the proper use of a background thread? I would also like opinions on the best method for pausing execution until the specified time.
View 4 RepliesI want to gather some data from some tables of an Access Database, I've found some solutions online, but I haven't found ways to fill a datatable, or dataset, and get each single field properly. Is it easier for me to get whole tables then get just the info that i want, or should I make a lot of searches in the access DB getting just what I want each time? Any code snippets for it? The Access Database is in an ACCDB file, with no user or password. I'm currently using VB.NET, but it doesn't matter if you answer in C#. [URL]
View 2 RepliesI have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?
View 1 RepliesI am making a report using the reportviewer. I have grouped the data and the group works. But when I try to put some data in the group header, I get the following error:The Value expression for the textbox Dep_Name refers to the field Dep_Name. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.
The data I am trying to display is from a different table then the one that I am using to group the data. Does this mean there is a problem with the relationship between the tables?

My VB.net application has a lot of application settings, is it possible to group them somehow(other than having a common name)?For example, my application has a lot of winforms each of which needs to save some information about itself. Is it possible to use something like:

Form2.width = My.Settings.Form2.Width
etc.
I've a large table of Items and I need to organize them by Category, then by Year and then by Month.Item has CategoryID and Dated properties.I got this far:
Dim Items = From Item In DB.Items _
Group By CategoryID = Item.CategoryID _
Into Categories = Group _
Order By CategoryID
But where I put the:
Group By Year = Year(Item.Dated)
and the
Group By Month = Month(Item.Dated)
The final result should be something like this:
For Each Category in Categories
For Each Year in Category.Years

I am using a nice shopping cart I found online. I would like to translate this code to use a repeater or listview and dynamically retrieve my data, but I cannot seem to find a way to group my data correctly.I know the ListView can group by a certain amount of items, but I have not found a way to do it with this scenario.The shopping cart works by having a ul list of items, followed by their details in the div below. This process starts again by getting three more ul items, followed by three more details. How could I do this using a ListView or repeater? I have not found a way to repeat both of these sets of data I need in a group of three.[code]

Because all of my applications begin with the product in the Title bar can this be achived.
I have multiple sub's that i'd like to group together, however all of the groups need to be in the same class. They all work together, but it would help me organize the code and make it less confusing if I could group some of the different subs together for outlining purposes. Is there a way to do this? I tried to find answers online, but I couldn't find what I was looking for.
View 3 RepliesI have a class called Trigger. within this class, I can perform a variety of functions, the main of which is to monitor a specific condition. In this class I have a bunch of class variables that are used to setup the condition as well as for information purposes after the condition has executed. All the conditions are stored in a database and when I start the program, I create a New Trigger class for each condition and store the variables (name, desc, action to perform once the condition is met, etc.) I was thinking about changing the class to create a Structure called Configuration where I would store all the variables. But then I would have to save the Configuration within the class so it could be used later on if needed correct?
[Code]...
but in looking at this i realized that I am creating a new structure and then creating a new trigger class where I am saving the Configuration structure which essentially seems the same as just using class variables as I was before. I also looked at creating a Configuration Class and a Trigger Class. then from the main class I would create all the Configurations and have a shared Trigger class that monitored all of them instead of having a single Trigger class for each Configuration. Using this method i could create a hash table that kept track of each configuration that was being monitored and stop it if required.
Does either method sound more appropriate over the other. I am just trying to understand when/why to do things a certain way.
I did attempt searching but it just gave me a "505 bad gateway error".So my issues is the grouping header isn't working lol.
