Communications :: Converting Numbers To Strings And Vice Versa
Oct 23, 2009When sending numbers over my server/client, I need to first convert them into strings and pack them together into larger strings, then deconvert them at the opposite end. I need to ensure that they occupy exactly the correct number of spaces in the string - for example I need an integer to use up 4 spaces. So for example, if I had a byte, then 2 integers, I need the first character to contain the byte, characters 2,3,4,5 to contain the first integer and 6,7,8,9 to contain the second integer. Then I can retrieve each number from the string using Mid(Position,Length) and convert it back to a number.I know how to convert bytes using chr and asc, but how would I convert my integers into my string and ensure they occupy the correct number of spaces in the string (and back).All the conversion methods I've looked don't seem to fit the bill. Will I need to write my own function to achieve this?

View 1 RepliesVS 2010 Gradient Color Text Tool - Strings And Numbers
Jun 11, 2011I am making a gradient colored text tool for a game I play where they use a 3 digit number as an RGB color code before text. Making gradients by hand is tedious, as to do a gradient you type one letter at a time with an RGB code that changes by 1 in front of each letter.
example: "^090H^190e^290l^390l^490o" Would be a color gradient for Hello
I have a user input text into a text box and choose up to 6 colors. The colors then are assigned RGB values, only instead of 0-255 they are 0-9. (So they look like this 000=black 999=white 090=green, etc.)
I have figured out how to do this, but now I need to place the RGB values in front of the users text while only changing one of the RGB numbers at a time.
So if the color values are 090 and 900:
"090 190 290 390 490 590 690 790 890 990 980 970 960 950 940 930 920 910 900" is what I would like generated with the users text spaced evenly between.
I have no idea as to how I would go about putting three digit color codes between the users text or how to change the color codes one number at a time. I could try to do this on my own but it would be sloppy and probably a lot more code than needed (I have a feeling I should be using a loop or something like 'for each')... It's been awhile since I opened VB!
Way To Concatenate List Of Strings Into A Comma-separated Strings, Where Strings Are Members Of An Object?

View 2 RepliesRandom Numbers And Random Strings
Nov 24, 2009I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.

View 39 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
Find Strings Inside Strings?
Aug 15, 2011I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 2 RepliesDataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings
May 14, 2009I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.

Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

View 1 RepliesBox - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers
Oct 4, 2011I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
Program To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected
Mar 6, 2011I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
