Value Changing Cell Formatting

im using a vba macro to open a workbook and bring values into specified cells in the current workbook.... however when i do this its changing the cell formatting and then the info is coming up as dates instead of how it should look, is there a way to stop this? here is my code....

Dim wb As Workbook
Application.ScreenUpdating = False ' turn off the screen updating
'On Error GoTo error1
Dim RunNum As String
RunNum = Range("N9").Value
Set wb = Workbooks.Open("X:FrontEndChip FabFacet CoatingFinished Eddy Runs" & RunNum & ".csv")
With ThisWorkbook.Worksheets("Sheet2")
.Range("C3").Value = wb.Worksheets(RunNum).Range("C3").Value 'run#
.Range("G3").Value = wb.Worksheets(RunNum).Range("G3").Value 'Date
.Range("J3").Value = wb.Worksheets(RunNum).Range("J3").Value 'Operator(s)..................

NOTE* the info being read into the worksheet looks like this 12-2 or 10-1 or 12-12 but if it would stay as TEXT like i have it set to instead of changing itself to date format it would work just fine
