Using Split Method - Error: Char Values Cannot Be Converted To Integers
Feb 10, 2009
i have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data. Below is code I used to get the data when the Save button is clicked. [Code]
Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part. Plus even then I don't know if this would do what I want. EDIT: Ok I fixed the error and got it kind of working, but now I have a new question. Now, I put a button on the form that I can use to load the data when I choose to just to test. This works, it takes the data from each time slot and loads it back when I click the button. New question is how can I get it to load as soon as I open the existing appointment? Putting it in the form load event won't work because it checks for data before there is any in there.

I'm trying to use this overload
Split(ParamArray separator() As Char, count As Integer) As String()
However, when I use this
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, 2)
I'm getting the ArgumentException (Illegal enum value: 2)
I tried using named arguments with no effect:
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, count:=2)
Using this overload didn't weed out the error either:
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, count:=2, options:=StringSplitOptions.None)
The error is occuring only at run-time. Intellisense swallows it without problem.

This should be fairly easy, yet I have no idea on how to approach this. Perhaps the split command . Anyway, what I need to do is split as string into two integers.
For example MyStringXS = "10, 20"
I need to end up with:
MyIntegerX = 10
MyIntegerY = 20
BUT!
These strings obviously change. So it could be MyStringXS = "120, 230" Or MyStringXS = "12340, 20342" And so on.

I'm trying to split an inputted string (txtStart.text) into separate integers. The split function works fine for me, but I can't figure out how to store the each part of the array... This is my current code that I based on an example from MSDN library:
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
SplitStringIntoWords()
End Sub[code]......

I've mainly been recording keystrok macros... I created visual basic code that allows the user of a template to hide table gridlines - which works fine. The code to show gridlines does not work if the table has only one row. Here is the code - it is getting "stuck" on the
.LineWidth = wd
LineWidth050pt for a horizontal border, as there isn't one. I don't know how to change the code to not execute the command if a horizontal border line does not exist.
With Selection.tables(1)
With .Borders(wdBorderLeft)
.LineStyle = wdLineStyleSingle
.LineWidth = wdLineWidth050pt
.Color = 5592405

I have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient
Dim test as New Service1.Class1
test.P_integer = 1
[code]....
how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.

Using VB.NET - I have a string:
"##RES00012##Some value ##RES00034##Another value"
That I want to split using the "##RES" as a seperator to:
"##RES00012## Some value " and "##RES00034## Another value"
The string.split function doesn't seem to offer an overload to split on multiple characters or array of characters and maintain the seperator, which is required for functional purposes.
I'm looking at simply searching for indexOf("##res") and using string manipulation to do this unless I'm missing something obvious? I've searched SO for a solution but unable to find anything that actually does what I'm after.
The following is the closest i've found: how-do-i-split-a-string-by-a-multi-character-delimiter-in-c

I'm having some issues using the String.Split method, Example here:
Dim tstString As String = "something here -:- urlhere"
Dim newtstString = tstString.Split(" -:- ")
MessageBox.Show(newtstString(0))
MessageBox.Show(newtstString(1))
The above, in PHP (My native language!) would return something here AND urlhere in the message boxes.
In VB.NET I get:
AND
: (colon)
Does the String.Split only work with standard characters?

I need to test a string of text that needs to contain a certain type of char values. The known is allowing of a-z,A-Z,0-9. But the variable (which will be coming from a database field) will be the allowed symbols. The allowed symbols will look something like:!@#$%^&*()
So using regex, how can I check a string of text to make sure it ONLY contains a-z,A-Z,0-9 AND the allowed symbols as shown above? Remember, the allowed symbols is dynamic at run time so I need to somehow be able to plug that in to the method at run time.
The following examples would be valid using the above symbol string:
Test1234%
Test1234
The following example would NOT be valid:Test1234%_

I need to read this data into a string array. In my new file I need to write Name,Sal and Location columns only. Here is my code:

When I am splitting the above data, the sal column values which already contains "," is splitting into 2 cells. I want to keep the sal column value as a single cell by ignoring "," in between numbers.

I know how to count the "Char" in a word (using .Length), but for this assignment, I really have no idea how to count the words in a sentence. What kind of method am I supposed to use for this particular assignment?
