is there a way to accept user input and convert those inputs into command? e.g. i have a textbox that can "test" commands. when i type this into the textbox, it should run the command:
dim a = "asd"
msgbox(a & "fg")
I know there are work-arounds like using a Select Case, but in my situation, it would make things a lot easier... especially since I won't know exactly what will be entered. I can't force the user to use a combobox or anything like that either, because it is going to be unique code for every situation. If there is no way of doing this, I will figure something else out, but it will require a lot more work.

Then I need the program to count how many times, the letter appears in the phrase. I have everything set up.

How do I get numbers typed into a text box to be feed into my code and then the code to be ran?Below is the code that I want the information from a text box to be fed into. With the (0, 50) being the numbers.I will have a form set up like this, A button labeled Generate. 3 Text boxes total, 2 of them side by side with one being low and one high. For example The user will input 5 in the low box at 100 in the high box. Hitting generate the numbers will then be inserted into code and the result being shown in the 3rd text box.
Now what is the code that I'm looking for that will help me take information from TextBox1 and TextBox2 and insert into the (XXXX, XXXX) field in my buttons code?

Lets say I have 20 lines like this. I want to change this lines according to user input. So user will input how many lines they want to change in terms of row and column. In my program
Row=TextBox5.Text column=TextBox6.text
User must enter initial value for x and y. Let say the initial value is
x=1 y=1.
Row=2 column=5..
Now my lines should look like this.
1 1
2 1
3 1
4 1
5 1
1 2
2 2
3 2
4 2
5 2
x y
x y
x y
x y
x y
x y
x y
x y
x y

Since I enter row=2 only two set of lines is change other lines remain unchange. But in my coding all the lines is changing like this:
1 1
2 1
3 1
4 1
5 1
1 2
2 2

5 5
which is wrong.
This is my code
Dim lines() As String = IO.File.ReadAllLines("C:\wirematches.txt")
Dim xValue As Decimal = Val(TextBox1.Text)
Dim yValue As Decimal = Val(TextBox2.Text)
Dim altValue As Decimal = 2.54

I'm familiar with Visual C# and the try/catch for that but I cannot seem to figure out how to do the same thing in VB. Basically I can't figure out how to get the try/catch to work with text boxes and input from the user and whatnot.I've tried setting the textbox.text property = "" but that has no use, I've been trying to find something on Google about it but I cannot seem to find a single thing about textbox try/catch statements. Is it possible to do it with text boxes?
View 5 RepliesIs there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.
I have a text box labled QTY, which feeds the QTY column on a datatable. the table then is ran through a function that takes the data and converts it to a string which my production machine can read. My problem is this, and its probably really simple (these problems usually are) how to i force the user to use a specific type of input on the txtbox so they would have to put the QTY in the format of 01 02 03 etc etc, i have it set to default to 00 but i want to force the user to haver to input 2 chars.

1. Start System Information Program (easy)
2. Call a video test program, and send a couple arguments (see below)
3. Receive arguments from the video test (I do not know how to do this, I do not know how to send from the video test or receive from the system information)

View 1 RepliesThis is what I'm trying to accomplish: I have a Point of Sale application that integrates with a credit card processesor. I wan't to remove any user interfacing logic in regards to the credit card processor in the point of sale and add it to a application that sits in the background or system tray. I want to be able to send a command to the background app to popup a form for user input.
For example: User in the Point of Sale clicks a button "Credit Card" at this point it will send a command to the background app say "ProcessCC" which will pass a transactionid and an amount , this will open a form for the user to enter in the credit card information and submit the payment to the credit card proccessor.
Reason: I need to get a padss certification and don't want to submit the point of sale to do it. Rather send the simple background app that will control any credit card processing functionality such as encryption , storing etc. I know it can be done using sockets but was hopping for an alternative solution.
