How do I take the input of a text box as as string and write out a procedure for a button that takes the input and outputs a variable in the list box. For example i want to assign various values to strings such as the price of a chair = $10 and price of table = $40 . How do would you write it so that when you click the button it takes the word chair in the text boxs and outputs a value in the list box.
View 1 RepliesI have a USB device that is "seen" as a COM Port. It has eight channels, each require a single character to turn ON/OFF. It's a DLP-IO8 for reference.
1-8 turns ON each channel
Q-I turns OFF each channel
Sending a "124" will turn on channels 1, 2 and 4.
I want to randomize ON/OFF with "on-the-fly" speed control.
cmbSPRan.Value is my NumericUpDown starting at 1 and ending with 10
RandomNumber = RandomClass.Next(1, 87654321)
SerialPort1.Write(RandomNumber)
Timer1.Interval = (cmbSPRan.Value) * 250

I need a loop that I can still use the functions of the form (change speed or Stop loop).a way to utilize Q-I to turn the channels OFF randomly. I've tried Do Until, Do While loops and a few others.

1-8 turns ON each channel (12345678)
Q-I turns OFF each channel (QWERTYUI)
Truth table for device:
1 = Ch1 ON | Q = Ch1 OFF
2 = Ch2 ON | W = Ch2 OFF
3 = Ch3 ON | E = Ch3 OFF

I am checking for empty string values, but how do i see for the Quantity text box if the user chose only numerical values after the empty string. For example...

The program consists of making 2 text boxes, one labeled Age, and one labeled Name.The Name text box must return the name in all uppercase.If the Age text box isn't filled with a numerical value, you should receive a message saying "need a number" and return your cursor to the age box.2 command buttons "Process" and "Exit"

I'm trying to write a Database manager in VB (2010) that updates a SQL database that compiles and summarizes my financial records. The code works, but I'm having issues with one exception that I think I understand, but can't circumvent. I've built an I/O form that enters a series of purchases and sales into a temporary datatable. After review of the list, the program connects to the database and executes the SQL. That all works and isn't a problem.

View 2 RepliesI wish to extract numerical data from a text file and plot the data on a graph using the Zengraph classes. Each record has five variables.
I attempted to use the split function but failed to successfully get past one record.
1) How does one create an array or arrays using a text file containing many records, each with five distinct variables?
2) Is it better to create a number of single-dimension arrays or create one multi-dimensional array?
3) Is it easier to somehow convert a text file to an Excel file, with each variable in its own cell and each record on one row?
I have created a program and would now like to stop users from entering incorrect values/Text inside specific textboxes. For example i would only like text to be entered when a customer name is to be inputted and if a numerical key is pressed a message box will appear saying "sorry letters only" or something in that line. Also waould like it the other way round when trying to enter text within a number only text box.[code]...
View 1 RepliesHow would you replace a certain word from input to output? Like, if you type "Tigers are cool" in a text box I want the ouput after a button click to be "Lions are cool", changing 'tiger' to 'lion'. It should also be case sensitive so Tiger would convert to Lion, not lion.

The following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.
1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.
2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.
However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?

Okay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?
View 1 RepliesI have a javascript code that will output text in a separate textbox. Id like to try and do the same thing in my application now. Basically what I want to be able to do is type in a phone number and when the area code is entered to have it display the state.
Input textbox : 512
Output textbox : TEXAS
I have no idea if it is possible or how to do that.
I was working on a project and could not get the text output to be formatted like a table in text-box or rich text-box in visual basic 2010. Here are the code i have tried.
For i = 0 To 17
If cartfull(i) Then
rtbReceipt.Text = rtbReceipt.Text & vbNewLine & amount_added(i)

Basically, I want to have a text box that will display text associated with the text input.
For Example:
input : 512
output : TEXAS
or
input : 659
output : ALABAMA
I have heard that it is possible to do this, and I would like to find out a way to. Even if I need a separate text file with the arrays, I would like to get this to work.
I was have a code (shown below) but I am getting errors for the following line:
Code:
Dim line = lines.Where(Function(l) l.StartsWith(TextBox1.Text)).FirstOrDefault
