2008 - Using Split Method Shows 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.

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.
[code] Error4'Char' values cannot be converted to 'Short'. Use 'Microsoft.VisualBasic.AscW' to interpret a character as a Unicode value or 'Microsoft. VisualBasic.Val' to interpret it as a digit.
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]......
Ive been reading up on the split function on Msdn but grasp how if I had a text in textbox1 it would remove all spaces and textbox1.text and is split the easiest method?
I have an app that reads 2 colums of numbers from a .rtf textfile. The textfile is added to a textbox line by line in a counter. Now I want to split these values to 2 other textboxes. but I don't know how to proceed now. The .rtf textfile is 2 columns of data (imported from Excel), I need this format because it is a pointpair list for Zedgraph. If I use this code both number is added, theres no split:

I have split a string into a char array, now i need to copy the char array to an int array with the ASCII values of each char.Don´t know how to do it without looping each value.
This is my code:
origen = RichTextBox1.Text.ToString Dim valor As Char() = origen.ToCharArray Dim numeros As Integer() = (How can i convert "valor" to an int array?????)
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 [Code] .....
I'm having trouble assigning values to an array and am getting the error, "Value of type MemberFocal.Member cannot be converted to System.Array" - MemberFocal.Member is part of a custom class and I am attempting to create an array of these objects. Here is the code:
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.
I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
"##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.

If I have a datatble column set as int16 but rows can contain null values for this column. How do i write the linq query. I keep getting an error null value exception. Dim query = From n In resultstable.AsEnumerable Where n.value is dbnull.value does n't work.
I have the following vb code which works as expected when it's in a code-behind page. I tried to move it to a shared or component page since I will need to use it in multiple pages:
Imports Microsoft.VisualBasic
Public Class DetTime 'Determine eastern time

However the "if" statement shows an error " statement cannot appear outside of a method body" and the Microsoft solution is to "move statement into a procedure or subroutine"
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%_
However i get the following error: "Value of type 'String' cannot be converted to 'System.Uri" How can i set it so that it is set in the correct format?
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:
Dim ioReader As New System.IO.Streamreader("C:old.csv") ioLines="Name,Sal,Location" Dim ioWriter As New System.IO.StreamWriter("C:
[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 got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

I am trying to split an array into a jagged array for easy manipulation, but I am having a bit of trouble with the Copy method of Array.This is what I have:
Dim masterData()() As String = New String(splitCounter.Count - 1)() {} For i As Integer = splitCounter(0) To splitCounter.LastIndexOf(splitCounter) Array.Copy(ServerResponse, splitCounter(i), masterData(i) = New String(), i, splitCounter(i
