I've been working on this challenge for a while now without much luck. What I'm attempting to do is split a MIME byte response into its individual images. I am given the boundary to split on in the HTTP header but when I attempt the following code it doesnt work.
'boundary to split on

I am trying to split a string into array. I know about split, but it seems to need a separator of some type. Suppose I am going to be working with input like the following. 8561369 and I want to split each character of that string into an array. I tried something like this, but again Split seems to need a separator, I just keep getting the entire string in one entry of my array, not split. Dim values as String 'I am going to be populating this string variable via user input eventually, 'which is why I cannot just add spaces. values = "8561369"
[Code]...
I have the following string:
[URL]
I need to separate each value and put it in an array. typically it would be done by ".split". however I need it to be split in this order: 0, 50, 100, 200, 400 etc.. In other words, I need it to read the rows left to right. I have no problem separating each number, I just need it to read it in the specified order. I've tried the regexp and I forgot to mention that after each line there is a line break. I am not sure if this would impact the regex, but in any case, after i do the regex, I get the following order: 0, 6.65, 84..??, 35.... etc
I am not getting the order I need as stated above
Expected results: 0, 50, 100, 100, 200, 400, 218, 9.8, ???, 6.65, 6.31 etc...
I am going to follow some of the suggestions below by splitting up the string into separate lines initially. this code almost does that:
Dim fields() As String
fields = calculationText.Split(vbCrLf)
Unfortunately for some reason the spaces are lost. When i look into the array, all the spaces between numbers are lost. why?????????
I want to split a string with this array of char
Dim sepa As String = " '"",.;:(){}[]·#|-_<>+¿?=/&%$‚¬@!¡"
The question is how do I include in this string vbcrlf? So I can do the fallowing:
dim palabras as String() = RichTextBox1.Text.ToString().Split(sepa)
I tried:
Dim sepa As String = " '"",.;:(){}[]·#|-_<>+¿?=/&%$‚¬@!¡\r\n"
But it does not work.
The format I use in the file I am reading is this: [property name]=[property value],[property name]=[property value],[property name]=[property value], [etc...]

Really crappy title but i have spent the last hour thinking of a working around.
Summery: A textbox is used to list clients i work for, Uses the splitter ","
Being seven days of the work would some times requier 6 splitters looking like this
Breath, Kemp House, garden center, Garden Center, COEL, PPD, Town
As so, but what if i miss a day? Or i dont always work saturdays sundays. from the code below you will see i have not added any work around fora null value. My suggestion is to incorporate a <nw> (no work) tag, but the code needs to change <nw> to my own personal message that i choose.

I have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:

I have a string array (strValues()) that holds a large quantity of character data. I need to parse out characters that follow "*PN" and end with "*". I then need to store this data in a datatable so that I can loop through it afterwards and pull out the unique records to be added to an existing dataset. I've been trying to use basic "IndexOf" to get started but it tells me "Overload resolution failed because no accessible 'IndexOf' accepts this number of arguments". Is there a way to accomplish what I'm trying to do?Sample data: MS50*CF3224205*PNineed/thisdata*SD07JAN10*ED21JAN10

So I've been going around the internet looking for a way to convert regular text(string) into base64 string and found many solutions. I'm trying to use:
Dim byt As Byte() = System.Text.Encoding.UTF8.GetBytes(TextBox1.Text)

but it end up with an error saying
'ToBase64String' is not a member of 'System.Windows.Forms.Timer'.
I am trying to convert a TIFF image to a base 64 string.I have seen so much code on the internet like the one below, but I don't understand it .I dont know what to change so it converts my image(s).I want the outcome (the bytes) as a variable that I can use outside this function. Know how to do that?

My app receives a PDF as a base64, zLib deflated string in an xml file. At least that's the format I'm told it is in. It gets stored in a database, then I need to recreate the PDF from that string. I created a test app to figure it out. The function below takes the string and is supposed to return it in a decoded, inflated format which I believe I'll be able to use to rebuild the original PDF (I'm not there yet). I've done lots of research and found a few different libraries and ways to do this as well as received a java program from the developer who is sending me the PDF to use as an example. However I can not get the string to a usable format. Using the ManagedZLib.dll and the function below seems to get me the closest. As far as I can tell from debugging, everything works until I try to decompress:
zStream.Read(decompressedBytes, 0, decodedBytes.Length - 1)
This produces a "zLib error: -3". The only info I can find on that error is it is a 'data error'. There is very little other information on the web about it.
Public Function DecompressString4(ByVal origString As String) As String
Dim returnString = Nothing
' get the base64 content into String

I don't think the web server is trying to encode anything as there are no + symbols within the url string and I have just glanced over the two to compair they are the same.This returns a blank string whereas when I use the sections commented out in the first loop i get a really weired string back and when I use their simpleXor function it just returns complete nonsense.
I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

im already familiar with splitting variables into an array using a certain character e.g.
strtextfield = name,surname,dob
strpersonarray = strtextfield.split(",")
strpersonarray = (0)name
(1)surname
(2)dob
im wondering whether you can split one variable according to its characters e.g.
strtextfield = name
strpersonarray = strtextfield.split(unsure as to what char)
strpersonarray = (0)n

View 1 RepliesI am a little bit confused by the following VB statement
commands = Regex.Split(script, _
"GO", _
RegexOptions.IgnoreCase)
I know what regex.split does. I know what the first parameter is. The second parameter is what I'm confused by. I think it is using the word "go" as a delimiter to split the first parameter into an array of substrings. But I don't understand what that refers to.

I am currently working on a visual basic console application in Visual Studio 2005 which takes various csv files from an osCommerce web shop, processes them and writes the data to TAS Books accounts software with the aid of the Infoplex COM module.
I have 2 functions, one reads each line of a csv file into an array, and the second function uses Regex to split the lines array into the various fields before they are added to a structure.
There are something like 5000 records (lines) in the csv file, one example is as follows;
[Code]...
My problem is that due to the formatting of the product description in the example csv line above, it fails the Regex match and therefore fails to read.
I know this is because my pattern is wrong, but I'm not sure how to solve it, I think all I really need is for Regex to split the line by the "," between each element, this might be a little difficult because some of the descriptions contain both , and " but never one after the other.
I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:
21,Z920081
22,Z920082

120,Z930027
I'm trying to input this into an array and then a combo box using:
dim item as integer
dim array() as string
dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.

I need to Base64 encode a string, but the encoded string cannot contain "+". Wikipedia mentions a modified Base64 for URL, but I can't find a .NET class which uses this.For my application, I can't even URL encode "+" into "%2B". This is because I pass the encoded string to a service which I have no control over, and that service mangles any strings which contain "%2B". For this reason, I want my encoded string to only contain A-Z, a-z, 0-9, -, and _.
View 2 RepliesI need to split a string at all whitespace, it should ONLY contain the words themselves. How can I do this in vb.net? Tabs, Newlines, etc. must all be split!
