I am using VBA in Access to modify a excel sheet using Macro 1 and input it in a table using Macro 2. When I run both of these consecutively, my system gets stuck in a loop, but works fine if I restart the Microsoft access application after running one Macro and run Macro 2. Also at times, the excel file on which I am running my code gets a pop-up box to enable read/write access.. Can someone help me with it?

I am working on a custom VBA script that dynamically collects user-entered form data and inserts it into a MySQL database. My problem is, to convert form field data into an SQL script, I have to use string functions; thus, all my data, including dates, gets inserted as text. I need to convert all the dates the form collects from m/d/yyyy format to yyyy-mm-dd format for my MySQL database to infer schema and load date data into DB without an error. I need to do so dynamically, meaning, the script has to work regardless of how many date fields are collected. I have:
Private Sub Submit_Button()
Dim doc as Document
Dim control As ContentControl
Dim FormDateField As Date
Dim ReportNumber As String
Dim myValues As String
Dim myFields As String
Dim conn As ADODB.Connection
Dim strSQL As String
Set doc = Application.ActiveDocument
Set conn = New ADODB.Connection
conn.open "DSN=ABCD"
For Each control In doc.ContentControls
Skip = False
If Left(control.Range.Text, 5) = "Click" Or Left(control.Range.Text, 6) = "Choose" Then
Skip = True
Else:
myFields = myFields & control.Tag
myValues = myValues & "'" & control.Range.Text & "'"
End If
If Not Skip Then
myFields = myFields & ", "
myValues = myValues & ", "
End If
Next
myFields = Left(myFields, Len(myFields) - 2)
myValues = Left(myValues, Len(myValues) - 2)
strSQL = "INSERT INTO TABLE_1 ("
strSQL = strSQL & myFields
strSQL = strSQL & ") VALUES (" & myValues
strSQL = strSQL & ")"
conn.Execute strSQL
MsgBox "Form data saved to database!"
conn.Close
End Sub
However, my program is crashing because it is trying to insert a string into the date field (the actual final form will have many date fields.) I thought if I change the date format to MySQL format, it may be able to infer schema? I tried adding
If IsDate(control.Range.Text) Then
control.Range.Text = Format(control.Range.Text, "yyyy-mm-dd")
Else FoundOne = False
End If
and I know in Excel you can do:
Application.FindFormat.NumberFormat = "m/d/yyyy"
Application.ReplaceFormat = "yyyy-mm-dd"
Any suggestions? Thank you.
Assuming all dates are in date-picker content controls, you could use:
Private Sub Submit_Button()
Dim CCtrl As ContentControl, bSv As Boolean, DtFmt As String
Dim myFields As String, myValues As String, strSQL As String
With ActiveDocument
bSv = .Saved
For Each CCtrl In .ContentControls
With CCtrl
If .ShowingPlaceholderText = False Then
Select Case .Type
Case wdContentControlDate
DtFmt = .DateDisplayFormat
.DateDisplayFormat = "YYYY-MM-DD"
myFields = myFields & .Tag & ", "
myValues = myValues & "'" & .Range.Text & "', "
.DateDisplayFormat = DtFmt
Case wdContentControlRichText, wdContentControlText, wdContentControlDropdownList, wdContentControlComboBox
myFields = myFields & .Tag & ", "
myValues = myValues & "'" & .Range.Text & "', "
Case Else
End Select
End If
End With
Next
.Saved = bSv
End With
If myFields <> "" Then
myFields = Left(myFields, Len(myFields) - 2)
myValues = Left(myValues, Len(myValues) - 2)
strSQL = "INSERT INTO TABLE_1 (" & myFields & ") VALUES (" & myValues & ")"
Dim Conn As New ADODB.Connection
With Conn
.Open "DSN=ABCD": .Execute strSQL: .Close
End With
Set Conn = Nothing
MsgBox "Form data saved to database", vbInformation
Else
MsgBox "No form data found", vbExclamation
End If
End Sub
As you noticed, Word does not have Application.FindFormat or Application.ReplaceFormat, but if you know the format is m/d/y you should be able to do this:
myValues = myValues & "'" & ymd(control.Range.Text) & "'"
Function ymd(s as String) As String
Dim v As Variant
v = VBA.split(s, "/")
ymd = Right("0000" & v(2),4) & "-" & Right("00" & v(0),2) & "-" & Right("00" & v(1),2)
End Function
Everything else (e.g. the way you add commas to the list of dates) looks fine but I have not tested.
I am importing a series of CSV files into Access tables. I have the following line that imports each file:
DoCmd.TransferText acImportDelim, , FN, F.Path, True
This import statement works and creates the necessary table. However, it creates the field types from the data, and depending on the first few rows of the data it may create a field as numeric that should be text - and then causes an error when it encounters a text value later in the file.
How can I force the field type to Text for every field in the input file? I've used Import Specifications before, but first the file format (provided by others outside my control) may change from time to time, and second it's a very "wide" file with 200+ column, so this isn't a practical answer.
This is not a great workaround, but I had to go through the process anyway to get around the 255 field limit in tables. In short, the import steps I ended up with are
Read the 1st line of the file as an inputstream
Split the line to get the field names, put them in a data dictionary table and then manually mark the ones I want to import
Use CREATE TABLE to create a new data table (selected fields only) with all of the fields set to TEXT
Read each line of the file as an inputstream
Split the line to get the data for each field
Use INSERT INTO to add the selected fields to the data table
Cumbersome, but it solves both problems - I'm not limited to 255 fields in the input files and I can control the data type of the fields as I create them.
The code, if anyone cares, is

I've been using stackoverflow for over a year now but this is my first post so if I do something wrong, please let me know and I'll try to do better next time.
I'm currently using MS Access 2003 as a front-end data entry application with an MS SQL 2008 back end. A function used by just about every form in the app is breaking for no reason that I can determine when called from a specific subroutine.

When called from any other sub it works fine and returns the appropriate value. Please help.
I don't have an actual explanation as to why it was returning an error code but by removing the error checking the process worked. If anyone has an actual explanation as to what was actually causing the issue it would be greatly appreciated.

This code works as I want but "looks" slow even with a test DB with only a few records in each table.
I believe the time is spent (how can I check if this is true?) in the loop between comments.
Is there a more basic, obvious and efficient way to filter the form than creating a recordset and looping through it as I am doing?
The form "Libri" is a big one with several subform to be able to see all the data of a Book.
The query "Libri_All_Query" is a join of almost all tables in the DB and the code shown is executed from a form where I plan to add all possible search fields.
Forms have a filter property:
stWhereClause = "Title Like '" & Me.txtSearch & "*'"
Me.Filter = stWhereClause
Me.FilterOn = True
The filter should be constructed in a similar way to a WHERE statement. There are some limitations compared with Where. You may wish to check with DCount that records will be returned.
EDIT
If you want a set of records where a subform contains only certain records, you need something on these lines:
SELECT b.Title
FROM Books b
WHERE b.ID IN (
SELECT j.BookID FROM BooksAuthorJunction j
INNER JOIN Authors a ON j.AuthorID = a.ID
WHERE a.Author Like "Arn*")
There are advantages in building more that one form, books as a main form and authors as a subform, then authors as a main form and books as a subform. It is often easier on the user.
Im working with my project inventory system i want to display the filtered dates in my books table in the mysql in my listview1 using 2 DTPicker and make a report for it. Im having an error in my query in the classmodule idk if its only the query and im really confused im a begginer in vb 6.0...please in need your help guys.
Im using 2 tables namely books and supplier.

Sub DisplayList(ListView1 As ListView, DateFrom As Date, DateTo As Date)
Dim lstItem As ListItem, a As Integer
Dim rs As New ADODB.Recordset
Dim sql As String
If rs.State = adStateOpen Then rs.Close
sql = " SELECT supplier.category,books.title,books.dataAcquired,books.amount,books.quantity,books.accesionno,books.conditions" & _
" From supplier INNER JOIN books" & _
" ON supplier.code=books.code" & _
" WHERE (((books.dataAcquired)>=#" & DateFrom & "#) and ((books.dataAcquired) <=#" & DateTo & "#))" & _
" GROUP BY supplier.category,books.title,books.dataAcquired,books.amount,books.quantity,books.accesionno,books.conditions" & _
" ORDER BY books.dataAcquired DESC;"
rs.Open sql, cnn
ListView1.ListItems.Clear
Do While Not rs.EOF
a = a + 1
Set lstItem = ListView1.ListItems.Add(, , a, 1, 1)
lstItem.SubItems(1) = rs(0).Value
lstItem.SubItems(2) = rs(1).Value
lstItem.SubItems(3) = rs(2).Value
lstItem.SubItems(4) = rs(3).Value
lstItem.SubItems(5) = rs(4).Value
lstItem.SubItems(6) = rs(5).Value
lstItem.SubItems(7) = rs(6).Value
rs.MoveNext
Loop
End Sub
MY CODE IN MY FORM:
Private Sub Show_Click()
clsData.DisplayList ListView1, DTPicker1.Value, DTPicker2.Value
lblCount.Caption = ListView1.ListItems.Count
End Sub
Private Sub Form_Load()
DTPicker1.Value = Date
DTPicker2.Value = Date
End Sub
Private Sub Form_Activate()
clsData.DisplayList ListView1, DTPicker1.Value, DTPicker2.Value
lblCount.Caption = ListView1.ListItems.Count
End Sub
Change # by '
format date how yyyy-MM-dd or yyyyMMdd
sql = " SELECT supplier.category,books.title,books.dataAcquired,books.amount,books.quantity,books.accesionno,books.conditions" & _
" From supplier INNER JOIN books" & _
" ON supplier.code=books.code" & _
" WHERE (((books.dataAcquired)>='" & format(DateFrom,"yyyy-MM-dd") & "') and ((books.dataAcquired) <='" & format(DateTo,"yyyy-MM-dd") & "'))" & _
" GROUP BY supplier.category,books.title,books.dataAcquired,books.amount,books.quantity,books.accesionno,books.conditions" & _
" ORDER BY books.dataAcquired DESC;"
change loop while added validations for recordset emptys, some how
if RecordsetIsClosed(rs) then exit sub
While Not RecordSetIsEmpty(rs)
a = a + 1
Set lstItem = ListView1.ListItems.Add(, , a, 1, 1)
lstItem.SubItems(1) = rs(0).Value
lstItem.SubItems(2) = rs(1).Value
lstItem.SubItems(3) = rs(2).Value
lstItem.SubItems(4) = rs(3).Value
lstItem.SubItems(5) = rs(4).Value
lstItem.SubItems(6) = rs(5).Value
lstItem.SubItems(7) = rs(6).Value
rs.MoveNext
wend
Public Function RecordSetIsEmpty(ByRef rs As ADODB.Recordset) As Boolean
' On Local Error GoTo RecordSetIsEmpty_Error
' RecordSetIsEmpty = True
' If rs Is Nothing Then
' RecordSetIsEmpty = True
' Exit Function
' End If
' If RecordsetIsClosed(rs) = True Then
' RecordSetIsEmpty = True
' Exit Function
' End If
RecordSetIsEmpty = (rs.BOF = True And rs.EOF = True)
' RecordSetIsEmpty_Done:
' Exit Function
' RecordSetIsEmpty_Error:
' Resume RecordSetIsEmpty_Done
End Function
Public Function RecordsetIsClosed(ByRef rs As ADODB.Recordset) As Boolean
On Local Error GoTo RecordsetIsClosed_Error
RecordsetIsClosed = True
If rs Is Nothing Then
RecordsetIsClosed = True
End If
If rs.State <> adStateClosed Then
RecordsetIsClosed = False
End If
RecordsetIsClosed_Done:
Exit Function
RecordsetIsClosed_Error:
Resume RecordsetIsClosed_Done
End Function
Dont forget to open the database connection
updated thanks Mark Bertenshaw
RecordSetIsEmpty is use for problems when do movenext.. well i remember
RecordsetIsClosed is use because in some cases and databases managers return not recordset or the recordset is not correct initialized
for example access is necessary use movefist before do movenext or read values
