Excel 2007, VBA import new .csv files to update existing tab - excel

Question

I've just been acquainting myself with the VBA language and would appreciate any help. I'm trying to write a program that updates an existing tab with a new file.
Here's what I have so far:
Sub ImportFile()
'
' ImportFile Macro
'
' Keyboard Shortcut: Ctrl+Shift+I
' Clears active sheet
Cells.Select
Selection.ClearContents
Range("A1").Select
' "Open" prompt window
Dim aFile As String
aFile = Application.GetOpenFilename(FileFilter:="Comma separated values files, *.csv")
If aFile = "False" Then Exit Sub
' Import .csv file to active sheet
With ActiveSheet.QueryTables.Add(Connection:= _
"TEXT;C:\Users\jiarui.hou.THRUBIT\Desktop\thrubit\data\PS25R_175c_20110711_proc1.csv" _
, Destination:=Range("$A$1"))
.Name = "PS25R_175c_20110711_proc1"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.RefreshStyle = xlInsertDeleteCells
.SavePassword = False
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.TextFilePromptOnRefresh = False
.TextFilePlatform = 437
.TextFileStartRow = 1
.TextFileParseType = xlDelimited
.TextFileTextQualifier = xlTextQualifierDoubleQuote
.TextFileConsecutiveDelimiter = False
.TextFileTabDelimiter = False
.TextFileSemicolonDelimiter = False
.TextFileCommaDelimiter = True
.TextFileSpaceDelimiter = False
.TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, _
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
.TextFileTrailingMinusNumbers = True
.Refresh BackgroundQuery:=False
End With
End Sub
But the problem is in the first two lines of the third part, it directs to a specific file. But I want the program to import ANY file that I had specifically selected. I guess what I'm asking is how do I link the second part which prompts a window to open a file, to the third part which links that directory address in place of the current SPECIFIC directory address.

Answer 1

Use the concatenation operator & and make the string that you pass to connection be "TEXT;" & aFile
With ActiveSheet.QueryTables.Add(Connection:= "TEXT;" & aFile, Destination:=Range("$A$1"))
Also, I think instead of "False" you want False on the 7th line.
