I want to force all capitol letters in a label and when text is input into a text box. How can I do this?
View 1 RepliesIm extremely new to programming. Im trying to determine how to get values from 6 different text boxes put them into an Array. They are in a function not on the form. Three of those values need to be used for calculation.
View 14 Repliesi got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
in my text file i have two part. Called bottom and top. So i need to read the Top part first then and match the line with bottom part. Its like this

I'd like to know if it is possible to refer to section of an array. e.g.
dim a(10) as integer
foo(<reference to array a starting at item 2>) 'only use items 2 to 9 of the array
...
sub foo(byref a() as integer)
<do something with array>
end sub
Note that I don't want to copy the array to a new array or pass in indices, if I can avoid doing so. Subroutine foo should be able to process the array without knowing if it gets the whole array or just a section.

I am working on an assignment where I need to have a product list that is loaded into a list box upon the form loading. This is generated from a txt file in the /debug folder upon loading. Now my question is how do I have the product names show up in the list box when there are 3 separate parts to each product. The product, the cost, and the quantity in inventory, and all I want to show up is the product in the listbox, where the rest show up elsewhere.
CODE:
'This procedure loads the data for the array from txt file. As well as loading the Product.txt file into the system when the program loads.

View 9 RepliesI am having some trouble with an array full of data which I am trying to process. The data has been picked out of an Excel spreadsheet and contains items such as phone numbers. The problem is that when I drop this array back into a spreadsheet, Excel being clever, decides that some of the phone numbers are numbers and removes the "+" from the front.[code]...
I know that adding a ' in front of the + will remedy this. What I need to do is find out which of the numbers in the array are actually numbers and which have spaces/characters in them. IS there a quick way of doing this without having to search through each individual character of each array position?
I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?

Dim BigNumber As Double = 2 ^ 1000
Dim DigitArray() As Char = BigNumber.ToString.ToCharArray
Dim Index As Integer = 0

View 14 RepliesI'm trying to make a text ecrypter/decrypter were I can choose how it gets encrypted. So i'm using the 'Replace' method to replace a letter to a different letter. But what happens is, only some of the letters convert correctly! What some a doing is converting themselves twice. So if A gets replaced by B and B gets replaced by A, if i entered A, it would convert to B, then back to A.[code]...

Okay, this is more than just a find text and replace it. how to select only certain letters ( such as A and T will be used in this example ) and replace them with another. For example, I have a document that says:
Hello this is a test application. Thank you for testing!
and i save it, i want it to in a way to encrypt it, what do i mean? i mean like replace all the letters with other, then apply the opposite code for opening the file to "decrypt" it. Like what i would replace is something like change all the A's to T's. But the thing is i need to do this for all the letters. Im sure there are places on how to find and replace text, thats easy, but is there a way to do this in simple lines of codes without having to write a seperate code for all 26 letters?
I'm keeping track of some things that are numbered and others that are lettered; while NumericUpDown is perfect for selecting numbered things, I need an analogue for selecting lettered things. The obvious choice would be a listbox that just contains all the letters of the alphabet. But I need to show only the appropriate range of letters, so if I want to use a listbox, I need to write a function that populates the listbox with the first n letters of the alphabet; if n > 26, it should continue with aa, ab, and so on. How do I do this?
