I have a table with Zip CODE field. I uploaded my information to this table form an excel file. There were over 120K rows of data so no way i could do this in excel.
So I found that some of the ZIP codes are either blank or have less than 5 digits.
Can I build a a query with the ZIP code field that will return all zip code records with less than 5 characters or blank. I'd like to repair these zip codes and a update query will be my next step.
I repeat excel is not an option because when I try to sort by the Zip Code column my computer explodes (okay not literally) ....

Copying a column from one record to another. Code is:
Code:
Set fld = Records.Fields("violationLocalOrdinanceNumber")
If Len(fld & "") > 0 Then
rst!LOR_NB = Nz(Records!violationLocalOrdinanceNumber, "")
Debug.Print ("LOR NB:" & rst!LOR_NB & "." & " len:" & Len(Nz(Records!violationLocalOrdinanceNumber, "")) & " len new:" & Len(rst!LOR_NB))
End If
Some of the output I'm getting is:
LOR NB:8.08(5) . len:7 len new:25
LOR NB:7.08(5)(a) . len:10 len new:25
LOR NB:7.08(5)(a) . len:10 len new:25
LOR NB:7.08(5)(A) . len:10 len new:25
LOR NB:7.08(5)(A) . len:10 len new:25
LOR NB:7.08(5)(a) . len:10 len new:25
LOR NB:8.08(5) . len:7 len new:25
No matter what the original string length is, something is adding extra spaces and forcing it to 25 in the new record. This is the only field I've been able to identify with this issue. Column definition is char(25), no indexes or anything special that I can tell.
Tried adding a left() function call after the assignment but that didn't work either.

I have a Memo field that is used to be a description of a document. I don't know what the user will put in (could be anything), but it is eventually passed in a string to a query, etc.I discovered during testing that if an apostrophe is entered (Ex: This document explains how to deal with Joe's pleasant disposition.), it breaks my code. I then realized that all reserved words and characters would cause this problem.
I can get around this one just by using Replace(str, "'", "''"). However, I know there are others that will cause problems, and I don't want to end up with a string of replace statements just to fix them.

}
I'd like to run a query on tb_data.title that would replace any matching characters in tb_special_characters.character with nothing (I remove and close any spaces).

Is there an easy way in VBA to loop through a recordset and determine if the text string in a text field includes numeric characters?
I'm trying to do something like this:
Code:
Do Until rst.EOF
rst.Edit
If Left(rst!FldText,10) contains any numeric characters Then
rst!FldType = "Mixed"
ElseIF Left(rst!FldText,10) contains "PO" Then
rst!FldType = "PO"
Else
rst!FldType = "Std"
End If
rst.Update

I've got some code that loops through a record and copies the non-null fields to another record. This is the partial code:
For Each fld In tdf.Fields
If Not IsNull(Forms!contact_lookup![Contact_sub subform1].Form(fld.NAME)) Then
strSql = "UPDATE tbl1 SET tbl1.[" & fld.NAME & "] = '" & Forms!contact_lookup![Contact_sub subform1].Form(fld.NAME) & "' " & _
"WHERE tbl1.[FC_APN] = '" & Me.txtApn & "';"
DoCmd.RunSQL strSql
End If
Next fld
This works fine until it encounters a field whose contents has a reserved character, like a single quote (" ' ") in it, for example, "What's the what." At that point the SQL thinks there's a " ' " missing in the statement, and I get an error 3075 (syntax error: missing operator).

I use the below code as part of a database which creates documents and then saves them using data from the form fields.
Every now and again one of the form fields contains a "special" character such as /,@,& and this prevents the file from saving.
Is there a simple addition to the below code to remove special characters from the file name if there is one present?
It causes all sorts of issues as many people don't realise that there has been a problem until it is too late.
Code:
objWord.ActiveDocument.SaveAs2 FileName:="C:UsersPublic" & Forms![Front Page]![Site 2 Name] _
& " " & Forms![Front Page]![Combo79] & " " & "O2" & ".doc"
objWord.ActiveDocument.Close

The excel worksheet that I am importing into my database has some formula's, for an example =2+2. I am importing this worksheets, then checking fields against the main table, then exporting back to Excel. But I want to be able to keep the "=" signs when I import to remain so that when I export back into Excel the columns with the formulas will already be there.

I have an asset database I am designing to manage our computer inventory and assets.
I am trying to get a DLookup to work with one of my forms that will auto-populate some of the fields depending on what is entered in to the ProductID field. For instance, Make, Model, Asset type...
My problem is that the string that returns contains special characters, specifically "#" and gives me the error message -
Run-time error '3075':
Syntax error in date in query expression 'productID=EN371UA#ABA'.
My expression is definitely working, it just looks like it things it has something to do with date/time which it does not. Unfortunately, most HP equipment contains a # in the Product ID number.
Here is my expression -
Private Sub ProductIDCombo_AfterUpdate()
Make = DLookup("Make", "productlist", "productID=" & [ProductIDCombo])
End Sub
Make is the field I am looking up from the ProductList table. The Product ID is the ID I'm looking up from the ProductList table to find the make. My problem is actually getting it to return the correct value of "HP or Dell or Lenovo". etc.

So I have a login system established with loginID, passwords, and different user types. I also have a User Change Password form. However, this form only allows the user to change their password to something new. Also, for some reason the form only allows the first user in the table (ID#1) to be changed regardless of who is logged in. I was using an embedded Macro. I need to be able to have the old password entered and verified before the password can be changed to something new.

Two Solutions to address moving an Access Memo field into Excel when string has > 255 characters. All my 'reports' use Excel VBA (Access Reports are not used). The Excel reports can have 40,000 records. Speed to create the report can be an issue.
Describing 2 Solutions below to address moving Access memo fields with > 255 characters into Excel.After running this code
Code:
720 ObjXL.DisplayAlerts = False
ObjXL.Columns("X:X").Select
ObjXL.Selection.NumberFormat = "@" ' set column to Text
730 ObjXL.Worksheets(intWorksheetNum).Cells(intRowPos, 1).CopyFromRecordset rsNutsAndBolts
The Comments column are limited to 255 characters. So, the CopyFromRecordset (recordsetvariable) creates the 255 character limitation.
The reason? The 255 character limit is because CopyFromRecordset sutomatically uses the Characters property of the Range object. The 255 limit would not be there if the Cell Value property is used to assign the string to that cell.
Dim sRx as String ' String Prescription
sRx = "String with > 255 characters ... you fill in the rest ...."
Cells(1, 1).Value = sRx ' Cell's Value property assignment can be very large
Solution 1:
The record set is still in memory. By using a loop, a cursor can start with record 1 (memo column) and assign that value to the Excel row / column using the .value as shown above. Basically, this moves one memo field at a time, record by record. e.g. Read First recordset in Access, copy to variable, assign value to Excel row/column Then move next on each Access and Excel.
Solution 2:
An Access Memo filed [RxNotes] can have up to 750 characters. Cut it apart into three new fields that end up out in the very right Excel columns AA, AB, AC.
Note1=Mid([RxNotes],1,250)
Note2=Mid([RxNotes],251,250)
Note3=Mid([RxNotes],501,250)
Then using Excel Object - Concat the cells back cell by cell...
X2=CONCATENATE(AA2,AB2,AC2))
Then delete the columns AA, AB, AC to hide the evidence..Neither solution is all that elequent. Read about this and by golly, it made a difference
ConcatComments = "'" & CommentString
Before using the CopyFromRecordset be sure to add a single quote in front of the large string.
Turns out the interface between Access and Excel look for this to prepare Excel immediately for the string to be a string, not something else. Some of my strings had weird print characters that kind of looked like Japenese characters. It seemed random, it always happened if the string was 255 or more characters (ramdonly, not always). The single quote doesn't show up in Excel, but got rid of all the noise.

I would like to ask how can i validate the username and password in a textbox? I have a frmLogin and frmMain.
I have also a table called 'tblUsers' with column fields 'username and password'.
If username is not found in database then a msgbox will prompt 'Username is not yet created'.
If username is okay and password is incorrect then msgbox will prompt 'Incorrect password'
If username and password is okay, then a msgbox will prompt 'Successfully login' and will continue to frmMain.

I have a mdb file that does not have database or user level security, but it does have a VBA password.I want to transfer (overwrite) a new form to this database from another Access database. The form I'm exporting has VBA code. When I try using docmd.TransferDatabase I get an error. The error is:
"The TransferDatabase action was canceled."The line is:
DoCmd.TransferDatabase acExport, "Microsoft Access", txtCheckInFile, acForm, "SubformLineSummaryContractor", "SubformLineSummaryContractor", False, False
where txtCheckInFile is the location and mdb file name I'm trying to send the export.It might be because the form already exists. So, if I go into the database and delete form, and repeat the export I get the message:
"Microsoft protect this Visual Basic for Applications Project with a password. You must supply the password in the Visual Basic Editor before you can perform this operation."My question is it possible to transfer a form to a MDB that has a passworded VBA? I know the VBA password.If not, perhaps it is possible to remove the VBA password in the database (using VBA), make my export, and then add the password back in?

I'm new to access vba and I'm trying to create a login form. I have already my code to login but i want to validate the password in 'case sensitive' basis. Below is only what I've got so far.
Code:
Private Sub cmdLogin_Click() Dim login_validation As Variant login_validation = DLookup("Password", "tblLogin", "Username='" & Nz(txtUsername.Value, "") & "'") If Nz(login_validation, "") <> Nz([txtPassword].Value, "") Then MsgBox "Incorrect Password. Please try again." txtUsername.Value = "" txtPassword.Value = "" txtUsername.SetFocus Else MsgBox "Hi " & txtUsername.Value & "," & vbNewLine & vbNewLine & "you have successfully login!" DoCmd.OpenForm "frmMain" End If End Sub

I have a Back end (with password) which resides in a netdrive while the front end is installed in each individual users desktop, the problem is, some of the users netdrive was mapped in a different way (different letters..some are J others are G). I'm looking for code that I can relink the database to the front end in runtime, I did try to look in the net but I can't find anything that I can put the password as parameter.
this sample code from Dev is good, but i got an error because the database requires a password.where i can put the password?
Code:
Function fRefreshLinks(NewDbName As String) As Boolean
Dim strMsg As String, collTbls As Collection
Dim i As Integer, strDBPath As String, strTbl As String
Dim dbCurr As Database, dbLink As Database
Dim tdfLocal As TableDef

I have built a simple database (by no means complete) but I am after adding some further code into it. Basically on the form [FrmMain] I have a button that allows me to send a document to a relevant CSU contact. It finds the file name based on the info in the table TblResident. What I want to do is open the word document before sending and add a password to it using vba.
