Error : Index 0 Is Either Negative Or Above Rows Count

Jan 6, 2009

I have a button that is supposed to display a form:

Code:
Private Sub btnEditAssociate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEditAssociate.Click
frmEditAssociate.ShowDialog()
End Sub

Code:An error occurred creating the form. The error is : index 0 is either negative or above rows count.There is a database call on the form load property of that form, so the problem could be with that, but the when I step into the showdialog() call it produces that error on the show dialog line, so I can never see what is going wrong.

Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

MySQL Count Rows Count Rows And Gain Access To Other Information In A Row Based On Provoided Information

Oct 8, 2009

I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)

So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).

VS 2008 : Re-index Variables To Non-negative Integer Values?

Oct 19, 2010

I have a program that calculates values of a function, say f, with respect to another variable, say L.I have an array of f(L), for L going from 0 to a given integer value, say t-1 in steps of a value i.I need to export the values of this function to an Excel spreadsheet in a given column, and to do this, I would like to re-index the function f, since i is much less than one, and so the following loop I use (see below) won't work:

For L = 0 To t - 1 Step i
Sheet.Cells(L, 1) = L
Sheet.Cells(L + 1, 2) = f(L)
Next L

The first code in the loop will essentially load the values of L itself, at which the function is defined and calculated, and the next line will load the values of the function at each value of L.Since the indexes of the row and columns in an excel spreadsheet only go in steps of 1, I need to convert the indexes of the function, or the indexes to which L is loaded, so that it would be scaled so that the first entry corresponds to L=0, but the next is L=i, but loaded into row number 2, etc.

Count Rows For Particular Columns If No Data Then Ignore And Count

Oct 6, 2010

Declare some class level variables that will keep track of the sums for each column. For example:

[Code]....

During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?

Asp.net Mvc - Getting A Count Of Rows That Match In Mvc 3 Using EF

Oct 24, 2011

I have a mvc 3 app that uses EF. In one function I need to get a count of rows that match a statement. I thought I could just do it like this:

Dim _ClassCount As Integer = _CurrRegistrants.Where(Function(c) c.tues_class = _CurrCourse.course_ref).Count

But that stays at 0 even when there are 40 records that match the criteria.. I think I have the right idea I just need to change the syntax a little..

Dim _CurrRegistrants As List(Of reg_classes) = db.reg_classes.ToList
For Each Course In _courses.Where(Function(a) a.course_day = "Tuesday")
Dim _CurrCourse As cours = Course
