Hello, im trying to make a command button that once clicked imports a .csv file into a table, applies queries and creates a report.

So far i have..


***************Command button****************


Private Sub Command0_Click()


Dim strFilter As String
Dim lngFlags As Long

strFilter = ahtAddFilterItem(strFilter, "Access Files (*.mda, *.mdb)", _
"*.MDA;*.MDB")
strFilter = ahtAddFilterItem(strFilter, "dBASE Files (*.dbf)", "*.DBF")
strFilter = ahtAddFilterItem(strFilter, "Text Files (*.txt)", "*.TXT")
strFilter = ahtAddFilterItem(strFilter, "All Files (*.*)", "*.*")

MsgBox "You selected: " & ahtCommonFileOpenSave(InitialDir:="C:\", _
Filter:=strFilter, FilterIndex:=3, Flags:=lngFlags, _
DialogTitle:="Hello! Open Me!")


DoCmd.TransferText acImportDelim, "", "tblImportTableTest", MYVARIABLE, False, ""

End Sub

In the command button code the bottom line says MYVARIABLE, this is part of where the code should import to the table. If anyone knows how to finish this bit id appriciate the help. Thanks, Marley.
 
I am not quite sure with you code so:-

Code: 
Sub GetCsv()
Dim strFilter2 As String
Dim strStartDir As String
Dim varFileName As Variant

'Set filter for file dialog
strFilter2 = "Text (*.CSV)" & vbNullChar & "*.CSV" _
& vbNullChar & "All Files (*.*)" & vbNullChar & "*.*"
' Set default directory to look in
strStartDir = "C:\"

'get file path
varFileName = tsGetFileFromUser(strFilter:=strFilter2, strInitialDir:=strStartDir)
If IsNull(varFileName) Then
    MsgBox "No File Selected!", vbCritical, "Selection Error"
    Exit Sub
End If

DoCmd.TransferText acImportDelim, "", "tblImportTableTest", varFileName, False, ""

End Sub

use this in conjunction with the code found at
http://www.access-programmers.co.uk/forums/showpost.php?p=459981&postcount=4
and see how you get on

ur code has varFileName, the purpose of my code was to give the user a choice of file and then import it. What is the purpose of the code you just linked me to? does it import to a database table?

thanks, Marley.
 
the linked code is similar to your module :)
its called by varFileName = tsGetFileFromUser(.... to allow the user to browse for the file.

It should import using your DoCmd.TransferText acImportDelim, .........

Peter
 
my code works

Yeah what i mean is my code works and allows the user to browse. Its the

DoCmd.TransferText acImportDelim,...

is the problem. MYVARIABLE should be an actual variable but i dont know where im declaring it
 
try something like

dim MYVARIABLE

MYVARIABLE = ahtCommonFileOpenSave(InitialDir:="C:\", _
Filter:=strFilter, FilterIndex:=3, Flags:=lngFlags
MsgBox "You selected: " & MYVARIABLE , _
DialogTitle:="Hello! Open Me!")

HTH

Peter
 
again this line was lit up

DoCmd.TransferText acImportDelim, "", "tblImportTableTest", MYVARIABLE, False, ""


but this time i got the error:

The action or method requires a file name arguement


Any idea what that means?
 
again this line was lit up

DoCmd.TransferText acImportDelim, "", "tblImportTableTest", MYVARIABLE, False, ""


but this time i got the error:

The action or method requires a file name arguement


Any idea what that means?
 
did the message return the correct path/filename?

try
DoCmd.TransferText acImportDelim, , "tblImportTableTest", MYVARIABLE, False


HTH

Peter
 
right when i hover over the code a box appears saying myvariable="" which makes me think im obviously missing something important. Yet im completely clueless to what it is.. any ideas??
 
did the message box show the file/path when the code ran? if not did it before I changed it?

Peter
 
yes

yes it allowed me to find the file and click ok, it then told me the name of the file i had selected. But after this it would debug.
 
can you post the onclick code that you have now please.

Peter
 
For the codes, how can we set to the "My Computer" location when calling the functions?

Thanks.
