Figure Out Different Ways Of Making Programs Work?
Jun 22, 2010
I've been going through a VB book I had while in College, and was trying to figure out different ways of making programs work.One assignment was to create a multi-dimensional array to figure out wind chill factors. The only part I really can't get to work right is using 2 numericUpDown controls. Using 2 dropdown menus was obviously easy because the items are indexed, but as far as I know, numericUpDown controls are not indexed.
Instead I used 2 selectCase statements to determine the index in each updown control, then passed the indexes to a function to determine the answer.The numericUpDown controls both increment by 5, (wind from 5 to 30) (temp from -20 to 15)Just looking to see if someone has any ideas of a better way of doing this.

I have two text boxes, submit button. and a dropdown list with the items(even, odd, and all). I want to calculate the sum of either all "Even", "Odd" or "All" numbers according the selection. In the code below, I have the "all" section working correctly but I'm trying to figure out a way to get the Even and Odd to work.
Some one suggested me to develope a good formula for determining whether a number is even or odd, then calling that from within the program as needed. I've tried that below with the IsEvenNumber function but got stuck. Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

I've not really got a lot of experience making any games, but currently I've only made small basic games which involve, moving picture boxes with Case (KeyDown) events and timers etc, I've noticed a few problems such as, flickering and jittery movements as it += on to Top or left. Especially when I try it on other computers it varies and is sometimes really bad. I've heard from my lecturer that you can use other things in VB.NET such as GDI+ or GDK or whatever, I'm not really sure, but would someone be able to explain to me what other ones there are for VB.NET or the best method for me to do to move on to more effective ways of creating a graphical interface.

I can't seem to find the correct words to search for an answer. I'm using VS 2010 so I have auto-implemented properties.I have a class and I want to access the properties by a string.
Public Class MyClass
Property Prop1 As String
Property Prop2 As String[code].....
But, I also want to be able to access the variables something like this way....
Dim MyVar = New MyClass
MyVar.Items("Prop1") = "Prop1 Value"
MyVar.Items("Prop2") = "Prop2 Vaule"
How can I setup MyClass to work both ways?

Below is the code I have been working on in VB.NET What basically happens is that when the user presses the calculate pay button, a message box is supposed to appear with all of the information in it, however the error comes up with: 'InvalidCastException: Conversion from string "Total pay: 5" to type 'Integer' is not valid.'
Public Class Form1
Dim TotalPayWithoutOvertime As Integer
Dim HoursWorked As Integer
Dim DoubleRate As Integer

I'm using the following code to read some values in from a tab delimited text file:
vb.net
Using Parser As FileIO.TextFieldParser = My.Computer.FileSystem.OpenTextFieldParser(LogFile, vbTab)
Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String
[Code]...
As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.

Is there a way to make ProgressBarRenderer.DrawHorizontalChunks actually work the same as the standard ProgressBar rendering?
If you create a Class that Inherits ProgressBar and override the OnPaint event then you have to render the Empty ProgressBar and it's fill% manually. This pretty easy with the ProgressBarRenderer. However, the DrawHorizontalChunks function is ugly compared to how a standard ProgressBar renders itself.
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle)
ProgressBarRenderer.DrawHorizontalChunks(e.Graphics, New Rectangle(0, 0,

I also have a second more minor issue in that I Shadowed the value property (for various reasons), so PerformStep (which then has to be Shadowed to keep the Value property in check) causes it to increase in blocks rather than smoothly growing between the two Values (old value growing to old value + step); the only solution I can see is to extend the code in the Shadows Sub PerformStep code to move the Value property gradually between the old and new values.

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

I started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..

When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.

My programming days are many years in the past - so I'm trying to get back into it. My current problem is as follows - I have a word document that is set up as a mailmerge document that is merged to email (through outlook). The merge records are in an excel spreadsheet (the email address is in a field called EMAIL). My emails are getting rejected by the recipient domain because they're being sent too fast (so they therefore think that they're spam).
I need to create a VB Program that will use the document called MASTER and merge it with the spreadsheet called RECIPIENTS and send via Outlook. However, I need it to send the first 10 emails, wait 10 minutes, send the next 10, wait another 10 minutes and continue cycling through until all of the emails have been sent.

I'm trying to figure out the 'bytestowrite' command, but I'm not having much luck.I'm sending some info over COM1 to and LED sign, and since it runs at 300 baud it takes a minute or so to transfer. I was trying to use the 'bytestowrite' command to find out how many bytes still needed to be sent, and use that info with a progress bar, but I'm always getting 0 when using 'bytestowrite'
Below is the code I tried to get the bytes left to write into a label box, but I've probably got it wrong (but I like to try to figure things out before I ask for help).
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Using com1 As IO.Ports.SerialPort = My.Computer.Ports.OpenSerialPort("COM1", 300, Ports.Parity.None, 8, Ports.StopBits.One)
Label1.Text = com1.BytesToWrite
[code]....
I thought putting it in a timer would keep checking the com port to see if there were any bytes to be written, but it always shows 0.

I found this code on here while doing a search and would like to be able to use it but it was written in C and I dont know much about that (don't know that much about VB.NET either but trying to learn)[code]What I do have is a text box where a user enteres a desired number of US dollars to convert to three types of currency.I know how to convert the string entered to an integer so the calculation can take place. What I don't know how to do is modify the above code so that the results will show up in the correct text boxes after each calculation (yes I know I have to convert the integer back to text).If someone could show me how to do the first Select Case I can figure the rest out.

I have a string with some custom formula like FVAL("A")+FVAL(B). I want to figure out all string inside FVAL() which does not have quotes around it.
So basically I want to extract out B because it does not have quotes around it.
