Export table to Excel Macro

I have a form with a command button set to execute a macro designed to export a table to Excel version 2003.

The VB code that is executed is as follows:

Private Sub LASARGrabToExcel_Click()
On Error GoTo Err_LASARGrabToExcel_Click

    Dim stDocName As String

    stDocName = "LASAR_Grab_Export"
    DoCmd.RunMacro stDocName
    Me.UpdateLASAREXPORT.Enabled = True

Exit_LASARGrabToExcel_Click:
    Exit Sub

Err_LASARGrabToExcel_Click:
    MsgBox Err.Description
    Resume Exit_LASARGrabToExcel_Click
   
End Sub

The macro name is "LASARGrabToExcel" and the table to be exported is named "LASAR_Grab_Export".

The macro was developed using the TransferSpreadsheet action. I hardwired the path and filename as parameters in the macro design view (see attached image).

What I would like to be able to do is to provide the user with a prompt to specify their own filename and path. I imagine this would need to be accomplished by modifying the macro code. However, I am not aware of how to access it. If there is some VB code I need to add, please provide detailed instructions on how and where to add it.

Thanks!

Open in new window


Then use it like so:
Private Sub YourCommandButton_Click()
Call ExportTable("tbl_YourTableName or your queryname")
End Sub

Open in new window

I pasted the code into a new module and named the module "SaveFile"

I then added:

Private Sub LASARGrabToExcel_Click()
Call ExportTable("GrabResults_LASAR")
End Sub

Open in new window


Upon clicking the button, I receive an error "Compile Error: Sub of Function not defined".

The debugger shows "Call ExportTable" as highlighted and there is a yellow arrow and highlighting over "Private Sub LASARGrabToExcel_Click()"

Is there something I am missing?
so this:
Private Sub LASARGrabToExcel_Click()
Call ExportTable("GrabResults_LASAR")
End Sub
 
would need to be behind a button on a form? where the item you are clicking is named "LASARGrabToExcel"

Is that the case?

Can this be easily modified to export a query to Excel?
no modification required, just pass in the name of the query as the table name

Great! I had another bit of unrelated syntax off, which was making me think the module needed to be modified. It is working well.

I am going to ask a related question regarding IMPORTING an Excel file and appending it to an existing table. Any code you may have for that would certainly be appreciated. Thanks again.
