The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Trouble with updating columns in excel via VB.NET

Asked by qz8dsw in Microsoft Visual Basic.Net

Tags: Visual Studio 2005 insert records excel ADO VB.NET

Hi all,

I've been tasked with updating a program that was written in VB5 around 10 years ago and updating it to VB.NET.
Although a complete re-write would have been advisable time to re-learn the original codes logic and re-write did not allow it.
So Yup, I used the convert wizard.
It's pretty much going great and even was able to get most of the old legacy VB code out.
One thing that did not work from start and is still not is updating a specific row and column in an excel spreadsheet with a value.
I've tried many and varied ways and spent 4 odd hours on google chopping and changing code to make this work.
I know I'm close, but not close enough.

Although I'll kick myself any help would be appriciated.

Cheers
Terry

Sub Update_Excel(ByRef intColumn As Short, ByRef strField As String, ByRef iRow As Short)
        Dim oConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Application.Info.DirectoryPath & "\" & strSpreadSheet & ";Extended Properties=""Excel 8.0;HDR=Yes;"";")
        Dim recordsupdated As Int16
        ' Open a connection to the Excel spreadsheet
        oConn.Open()
        ' This SQL statement selects a cell range in the worksheet.
        Dim oCmd As New System.Data.OleDb.OleDbCommand()
        oCmd.Connection = oConn
        oCmd.CommandText = "UPDATE " & strSSColumn & iRow & ":" & strSSColumn & iRow & " SET " & strSSColumn & iRow & "=" & strField 
        ' Open a recordset containing the worksheet data.
        oCmd.ExecuteNonQuery()
        oConn.Close()
 
        oCmd = Nothing
        oConn = Nothing
    End Sub
