I have written a small GUI based vb.net program that speaks to embedded devices via the com port. The GUI code contains a class which all communication to the embedded device is handled through (com port device, communication protocol, parsing info, holding device related info after each read).That class is called EDComms.
I wanted to add a thread so that the EDComms object could run in the background and report back as it downloads logs files and such (It can take a while to get log files from the device sometimes).So. Should I have EDComms inherit from backgroundworker thread? Or should I have a background worker thread as a member of EDComms?Right now I am going with the second choice. The only thing I have to do now is write a func for registering two delegates from the GUI for notifying task progress, and notifying task complete.Or is there a better choice than these two I have presented Perhaps have the thread as a member of the GUI?

Yup,not PHP but it's the same for readability)As you may imagine I want to make a simple text based rpg game, but that's not an important fact.The buttons btn1 to btn3 are already created at the designer, and there are going to be other procedures which will assign values to their text property according to the game context (main menu, combat, shopping, training, etc.) you're at.Ok, so what I want to do with that procedure I pasted is to parse the text of ANY of those buttons when I click them, and according to its value select a case which will trigger another appropriate procedure (now there are only msgboxes as placeholders for testing only).My problem is that I dont know how to refer to the originating class of the handled event! I mean, let's say I click btn2. I'll want to immediately get the text property of that button only and use it as the value for the select case tree. I suppose I need to put something at that ?I wrote there, but I don't have any idea. The first time I was so naive to put me.text in there, and of course it returned the form name. Is there's something to do this thing...? I thought at first it would be a very simple task, but I'm going nuts searching for a solution so it's like if it was not possible, but I find hard to believe that, because this would be very useful, right? By the way, what I want to achieve is not needing to make a separate procedure for each button and to avoid as well the need to move any game option to another procedure if later on I want to rearrange the menus, because I expect the game to have more than three buttons actually.

I'm setting up a simple app that has 2 variables, one from a combobox and one from a textbox.Putting all my code directly in the button1_click sub works just fine, however, I wanted to add a marquee progress bar so I tried to implement a backgroundworker.
[code]...
and call it with Me.Invoke(New SetComboBoxTextDelegate(AddressOf SetComboBoxText), ComboBox1.Text)but it still throws the Cross-thread operation invalid error.

I have a form with a few text boxes, one of which has it's contents stored to a integer variable.
The value stored will end up being one of a few numbers ranging from 12 to 98, and I need to the same number of new variables as the number in the textbox.
Can I automate the creation of new variables based on the value stored, or do I need to define the max number required and just ignore the rest when using less?

In my program I have a combo box that the user selects a date from and a list view that the user selects an employee ID from. How do I properly design my database query string to use both the date selected and the employee ID selected? The date is stored in a variable called YearMonth and the employee ID is stored in a variable called EmpID.
Here is what I am trying to do with my query:
Dim ExactQuery As String = _
"SELECT * " & _
"FROM[JobTypeExact_Query] WHERE (EMPID = ?) AND WHERE (YEARMONTH = YM)" 'Define Exact job type query

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

I am trying to set the variables, 'min and 'max' from user selected preferences. But, since the code where the variables go is outside of the private sub, I can't figure out where to put the code to retrieve the data from the file.

I have to display the available times in a dropdownlist called "DDL_avalTime" based on the date selected in a ASP calendar.
How the program works is that when a User clicks a date form the caldendar, it checks the SQL database. In this case the table that I'm retrieving it from is "trainerbookings" from the column "trainingDateTime". The data type for this column is datetime.[code]...

I want to populate the combobox based on the selected item in the first combobox. The following code is written in vb.net 2008
Public Class Form1 Sub fillcombo()
strsql = "select * from device"
Dim cmd As New OleDb.OleDbCommand
cmd.CommandText = strsql
cmd.Connection = con
[Code] .....
For this code I am able to populate the first combobox and when I select the specific item in combobox then the second combobox shows only the first element of that item.
In MS access 2007 I have created 2 tables:
1) Contains the device ex:computer
2) Contains the device and its parts ex: cpu, monitor so here the device has duplicate values
Table names are device and parts.
