Loop Through A String And Create An Array?
May 28, 2012
I have a string where I have created a template so to speak.
{
Dim myvariable as string
Richtextbox1.text = Richtextbox1.text & "The dog jumped over the" & myvariable & "to find the fox."
}
I have a list box that contains a list of options that loads into the variable example: fence, bucket, etc.
So the sentences would read like
The dog jumped over the fence to find the fox The dog jumped over the bucket to find the fox
Right now I have it coded to display into a rich text box but everything is in the same rich text box.
I'm trying to load the string into an array at the end of each loop this way I can then have each sentence separated.

Is it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.

I have a string array that represents the field names for a table I need to create. Given that the first field type is date, the second is time, and the rest are floats, what is the easiest way to create the table? I am currently using the following code, but it seems there may be a simpler, less convoluted way
vb
'read the column names from the OPC server
Dim colNames() As String = GetFileColumnNames().Split(","c)
'build command string used to create the table

I would like to format output to a property of a custom control I have made.For instance I have a literal control in my control and when populated I want to check if it is longer than 30 characters long, if so, then go to the next space (as to not cut the word off) after the 30th character and place a <br /> tag in to place the next 30 characters on the next line.So if there were 100 characters in a string, there would be 3 line breaks in the label.I have the looping worked out to get the label populated but cannot get how to dymaically create the array based on the string lenth property and index of method.

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

I want to know how to loop though this array so that when i start the program up it will start at the beginning of the array with the first prisoners details and then when i click "Next" the next prisoners details will be displayed in all of the boxes.

I'm writing a loop to go through the first array of a 2D loop, and I currently have it like this:
For Each Dir_path In MasterIndex(, 0)
'do some stuff here
Next
But it's giving me an error, saying it expects an expression in the first field. But that's what I'm trying to do, loop through the first field. How do I fix this? What would I put in there?
EDIT: to clarify, I'm specifically looking for the 0th element in the subarray of each array, that's why that second field is constantly 0.

I define a arrary.
Dim myStr(100) as string.
Then the length of this array is still 0. Then is risky to cross the bound. So how to intialize this array without using a loop?

I've been looking far and wide to find the answer to my question. Its probably has a simple answer, but I am new to VB2008 and can't figure it out. I have a web form setup 30 textboxes, and am trying to find a way to quickly add them to an array through a loop.Their ID's are all - TextBox1,TextBox2 ect. I have this loop here that runs with no errors, but nothing shows up in the TextBox's on the web form.If the TextBoxes are already on the form, do I still need to declare new boxes when trying to add them to the array?

This program is to display the monthly payment and amortization table for three mortgage loans with the same loan amount, but three different interest rates and terms.The ArrayIndex is not looping properly.The first loan displays correctly, but the other two only display the monthly payment and not the amortization table.[code]I originally had the For...Next loop in the DisplayAmortizationTable() sub with the Do Until loop nested in it. My instructor had me move the loop to the Main() sub, but it did not help.
