Private Function DisplayMoneyTaken() As Integer Dim totalMoney As Integer 'open the database connection
How can i get the index of an element in datatable which i got using the select method of datatable as
dim d as new datatable= 'some data source' dim dr() as datarow dr=dt.select("some condition")
now i want to find the index of first or second item which i have retrieved in data row. i mean there index in data table with out use of loops as loops take a lot of time when there is huge data in data table.
i have a 1 dimension boolean array and i need to get the index of the array element value = true.Anyone can point me a direction?I know i have to use.indexof() but when i try to use Variable.indexof(True) but it won't work.
I need a HTML element location (X and Y) in WebBrowser... Not the OffsetRectangle.Location one where you get a location coordinates inside parent element. I need a location coordinates inside the webbrowser...
im basically working on my final years project on the vb.net with the ilog business rules. i have trouble solving this error :Index and length must refer to a location within the string. Parameter name: length And the output show this :[size=2]
I am trying to import a text file into a data table using VB.NET. I need to loop thru each line of the text file and put certain elements of that line in a new row of the data table. The line may contain 50 elements, but I only need to get 15 of them. The very first line is a header row, which contains "File Name", "Object Name", "Object Weight", etc. The trick is the element locations move from file to file. For example, "File Name" element may be located at 0 in one file and then 15 in the next file. I need to find the exact location of my desired elements and save them to a variable. Then use that variable to locate the exact piece of data in the text file line to place in my new row.
The code below obviously doesn't work, but it kind of illustrates what I need to have done.
Try With dt .Columns.Add("fltObjectWeight", Type.GetType("System.Double")) .Columns.Add("vchObjectName", Type.GetType("System.String"))
numberofchar = timefull.Length If timefull = "" Then Else If numberofchar = 11 Then timefull = timefull.Remove(2, 9) ' isolate the hour depends on number of digits in hour parameter Else timefull = timefull.Remove(1, 9) End If End If This is my code, it doesn't work when I copy into form load. But when I try it in another form, it works. Index and count must refer to a location within the string. Parameter name: count
why this error happens with a bit of code i was trying? The code is actually intended to be for an onclick event, so it actually works there.
But im just curious as to why it errors as an onchange event. This is 9am pre-caffeine, so the reason is probably starring me in the face! On a form i have a text box, and a combo box. The combo box has various options in it, natch. Its a search form, which then fills a gridview with the results.
Drop down list options are: home number, mobile number, post code, Name, DOB
I thought id try and be "clever" and do away with the need for the combo box. Since a mobile number begins with "07", names are just characters, postcodes are character character number, and home number is all numbers and doesent begin with "07", and date of birth has /'s in it.
So i tried this to test the idea:
Private Sub AppSearchTB_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AppSearchTB.TextChanged Dim TLength As Integer = 2
I am trying to get the first 50 letters, so I used the subString function to get it. As you can see, I used this code to get it: <%# Eval("BannerDescription").ToString.Substring(1, 50)%>
But unfortunately it's not working and an error message is coming up: Index and length must refer to a location within the string. Because the user is the one who is controlling the data entry! Some times he gonna enter 10 letters other times maybe 1000 letter?
I tried them all but can we use it this way : <%# IIf(Eval("BannerDescription").ToString().Length > 49, Eval("BannerDescription").ToString().Substring(0, 49), Eval("BannerDescription"))%>
I keep getting the error saying that index and length must refer to a location within the string.
Public Class MainForm Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click Dim description As String = String.Empty Dim invCount As String = String.Empty
Consider the Statement: Dim pstr As String FileOpen(2, pfilepath, OpenMode.Input) pstr = LineInput(2) pstr = pstr.Substring(13, pstr.Length) Label1.Text = pstr FileClose(2) And it is Giving me the following error: Index and length must refer to a location within the string. Parameter name: length.
Dim Phone as string = "478-742-4050 478-256-6550" If _Phone.Length > 25 Then _Phone = IsNull(ReturnValue.Substring(0, 25).ToString, "") End If Return _Phone
Error: "Index and length must refer to a location within the string. Parameter name: length"
why error "Index and length must refer to a location within the string."appear when the process of the program is going to executeNonQuery, i'm looking the error for 2 day's i still can't find it.
I got this error and I don't know what should I do. Index and length must refer to a location within the string. Parameter name: length That's the line that i get the error on:

here is my codes below

[Code].....
the error appear when the program is going to update the 14th data... meaning from 1st to 13th data program works in the 14th it's not it gives me error "Index and length must refer to a location within the string

I am working on a very basic draw poker program. I need to analyze the hands. So far I have been able to identify a a pair, straight, a flush , and a straight flush. I'm not sure how to find three of a kind, full house, etc I have a function that uses a hash table to find out if there are duplicates in my array. I can use it identfy a sequence of cards. (i.e. if it returns a 5, that would be five cards in sequence) I'm not sure how to/if at all to use this for a pair , three of kind etc.. Maybe a differant approach would be useful. I've tried various pseudo code idea on paper and just don't see it.
