Syntax To Search (and Return Results) In Two Dimensional Array
Jan 11, 2012
The following code works just fine:
Dim wksSheetNames(0 To xlsWB.Worksheets.Count - 1, 0 To 1) As String
Dim i As Integer = 0
For Each Wks In xlsWB.Worksheets
Wks.Activate()
wksSheetNames(i, 0) = xlsApp.ActiveSheet.codename
[Code] .....
What is the best vb.net based search method that would permit me to search for i.e. "Sheet2" and be able to obtain "Cats"? I attempted to ascertain the index number of "Sheet1" with:
Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")
Then obtain the value "Cats"
wksSheetNames(SheetArrIndex, 1)
But I received an error message:
Code Line ->>>> "Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")"
Error msg ->>>> "Only single dimension arrays are supported here.:
Obviously I do not know how to Search and Return the results of a 2D array.

Currently I have a gridview bound to a datatable which is populated with groups from the AD. I need to be able to add search functionality so users can type in part of a group name and have the results display only groups that fit their search criteria.
Here's what I have so far.
<asp:TextBox ID="searchParam" runat="server"></asp:TextBox><asp:button ID="btnSearch" runat="server" Text="Search" />
<asp:GridView ID="dgSearchDLs" runat="server" AutoGenerateColumns="False" DataKeyNames="cn" DataSourceID="ObjectDataSource1">
<Columns>

Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above.
Actual Results: When Result(x) is true, all elements become Array1(x) and Array2(x) .What is wrong with the function?

So basically, I am running through my selected path recursively and returning the results to an array.. I think.
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim path As New FolderBrowserDialog
If path.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.TextBox1.Text = path.SelectedPath
[Code] .....
I was told that to return the search to an array, I add the return toarray() at the end.
Now obviously Im not getting errors, but I am also not polling the results that are in fileslist.toarray(). I've looked at arrays quite a bit, I see their functionality if they are defined like myarray(4) with 5 declared array values... its an array with 5 value places. And to read from any one of the 5, you'd say something like msgbox(myarray(3)) to call the 3rd place in the array.
Well, as you can tell from the code, I am putting a variable amount of information into the array, How can I call that information? If I scanned a folder with 300 files, how can I call the results of that array and put them in a text file, or console, or messagebox through them? And assume I am doing it through a button click event. So, button click to read all input in the array to console or something like that.

if label1 = RF350022
label2 = Increase

label4 = 100%
only if it contains all of these words it should return the first instance (row3) then end or null the rest (row4).how can i get row 3 to show in message box now it has been found?

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

I am having a problem understanding the following error message:
Value of type 1-dimensional array of string cannont be converted to 2-dimensional array of string because the array types have different numbers of dimensions This line seems to be causing the error:
New String((13) - 1) {}
I did a Google search on this but didnt come up with anything useful. I didnt even change the code.I just found this example online and copied/pasted it into a project that Im working on.

I am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I would like to create a vb form with a combo box (with song title), a text box (for song lyrics), and a button (to submit or refresh). It is linked with an access database. The combo box is populated with the songTitle field in the db (this part works fine). The text box is populated with the lyrics that go to that song The first updates fine but I can not figure out how to run a query to pass to the text box's text property. I want the user to be able to select a song from the combo box, click the button, and have the text box populated with the new song's lyrics.
Any suggestions on how to accomplish this, or a good place for a tutorial that explains the necessary elements for having vb query a database and return the results?

I am not a VB programmer, but I assumed for the most part that the syntax is C like, I received the program above from a non-technical recruiter with the following input f1("enritcde3 dtyeds4t8", 2). From my understanding the following output would be ("enritcde3 dtyeds4t8",2,2,2,""). Am I missing something?

I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...

I am developing an ASPX web page to return results from two SQL stored procs via VB. When I execute these two stored procs, they both return valid data. But for some reason, when I run this report it doesn't return any errors, however, it doesn't return any records/data either!
Also, I can't debug it for some reason, although I can set breakpoints! This is using VS 2008, but I think reason I can't debug is I believe this is a limited version that just works for SSRS and SSIS.
[Code]...
Could the problem be due to the fact that this web page uses the same SQL connection for both stored procs? The first proc should be returned initially, and the second proc after this screen. So I don't need both stored procs information simultaneously, so I would think I could reuse the same SQL connection.
OK, I found where the problem is located. If I just comment out the Level statement in the Where clause, it does return data. So only thing I changed was that one line in my SQL code and it works. This means missing data must be due to datatype incompatibility, no? What is the problem?
