VB App: “Comb Merge” Excel Workbooks

[Human2.0]

Greeting fellow Humans,

I'm trying to "comb merge" (if any thing as such) bunch of Excel files. There are 2 type of Excel workbook: A & B

Both has a column called : Location ID

These are the step I think the prog should do :

Promp user to select location of 2 file >> Read data from the user selected file >> Open pre-set Excel template paste item accordingly >> Save it!

Final Output: Same Location ID from both workbook in 1 sheet beside each other..

Possible? please guide me..newbie here..done my research Smile | :) **i can post picture of the files but i don't think you can on here

**Update: there are many pair of A&B files.Each pair of A & B files has different number of rows

**Here is how the interface looks like, just to gv an idea: http://www.imgplace.com/viewimg849/8800/45mergeinterface.jpg

Yes it's possible.
I might be easier to do and possibly use it with VBA from Excel, but it is possible to do it with VB.Net.

Imports Microsoft.Office.Interop.Excel
Imports System.Data.OleDb
Public Class Form1
Private Sub btnHT_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHT.Click 
OpenFileDialog1.ShowDialog()
If OpenFileDialog1.FileName = OpenFileDialog2.FileName Then
    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
ElseIf OpenFileDialog1.FileName = OpenFileDialog3.FileName Then
    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
ElseIf OpenFileDialog1.FileName = OpenFileDialog4.FileName Then
    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
Else
    lblHT.Text = OpenFileDialog1.FileName End If
End Sub

Else
    lblHb.Text = OpenFileDialog2.FileName
End If
End Sub
 
Private Sub btnRT_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRT.Click
OpenFileDialog3.ShowDialog()
If OpenFileDialog3.FileName = OpenFileDialog1.FileName Then
    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
ElseIf OpenFileDialog3.FileName = OpenFileDialog2.FileName Then
     MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
ElseIf OpenFileDialog3.FileName = OpenFileDialog4.FileName Then
    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)
Else
    lblRT.Text = OpenFileDialog3.FileName
End If
End Sub
 
Private Sub btnRB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRB.Click
OpenFileDialog4.ShowDialog()

    MessageBox.Show("File already uploaded!", "Try again", MessageBoxButtons.OK, MessageBoxIcon.Warning)

total 5 button : Header Top , Header Bottom , Report Top , Report Bottom & Merge.
I have created a template for the final output.

Report top & Report bottom will be paste in a specified cell = copy & paste concept.
Quantity: Header files has standard set of rows each time.

Below that

the Report top & Report bottom will be "comb merge. The primary key would be "Location"

So same "Location" id from Report top & report bottom will be paste beside each other..process goes on depending how many quantity it has.

Quantity: report files has random quantity of rows.

Simplified steps:
1-user selects all 4 files.
2-user click merge
3-data are read and paste in the template file
4-user prompt to save.
-HAPPY ENDING-
