问题 I need to validate an email field in a table in Access 2010. I tried: Is Null OR ((Like "*?@?*.?*") AND (Not Like "*[ ,;]*")) but this did not work. 回答1: It appears that your database is in ANSI 92 mode, and when you pasted in the rule... Is Null OR ((Like "*?@?*.?*") AND (Not Like "*[ ,;]*")) ...Access automatically changed Like to ALike , producing... Is Null Or ((ALike "*?@?*.?*") And (Not ALike "*[ ,;]*")) The problem is that ALike uses the ANSI wildcard characters, so you need to change

问题 In Access 2010, how do you open a database (created in Access 2003) which requires an .mdw file to be used? In Access 2003 you had to reference the .mdw file first. I can't find out how you would do that in Access 2010. Can someone tell me how to open the .mdb file in Access 2010? 回答1: To open an Access database that has user-level security enabled and does not use the system default Workgroup ( .mdw ) file you need to launch Access with command-line arguments that specify the database to be

问题 I would like to loop through all UNBOUND controls on my form and clear their data or reset their values. I have textboxes, comboboxes and checkboxes. Every time I try something like this: Dim ctl As Control For Each ctl In Me.Controls If IsNull(ctl.ControlSource) Then ctl.Value = Nothing End If Next ctl I get a runtime error saying: 438 This object doesn't support this property or method. 回答1: That code loops through every control in the form's Controls collection. The collection includes

问题 I have a login form to my database done in Access 2010 and using VBA code. I want to be able to press Enter on txtboxPassword and automatically execute btnLogin_Click event. I tried this: Private Sub txtboxPassword_KeyDown(KeyCode As Integer, Shift As Integer) If KeyCode = 13 Then btnLogin_Click End If End Sub What I get is a self-made error saying Password is incorrect. If I debug I see that actually txtPassword is null , but I just typed the text in it! However If I click the Login button

问题 A database created with one of the new sort orders will not open in Access 2007 even with Service Pack 2 (SP2) installed. 回答1: There is a list of compatibility issues : http://msdn.microsoft.com/en-us/office/cc907897, which includes sort order, however the big gottcha is not stressed, and that is General sort order. This is not the same as General sort order in previous versions of Access, it is new. For compatibility, you must choose General Legacy sort order. 来源： https://stackoverflow.com

问题 I am developing an information system that works with a connected data source / MS Access database. The question is kinda cliche but I can't seem to find a proper solution from the similar ones I have come across. Here is my code for the button. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'myConnection.ConnectionString = connString 'myConnection.Open() If Me.txtConfirmPasscode.Text = Me.txtNewPasscode.Text Then Dim updateCmd As

问题 Pretty simple explanation. I have a table with 10 entries, 5 entries with the year 2010 and 5 entries with 2011 in a column. In the query I have, I use Like *2010 to filter out all entries equal 2010 and display onl those records. On my form, I have combobox being populated with each unique year (from a different table). So my combobox values are 2010 and 2011. Is it possible, when I select say 2011, I trim the right 4 characters and use as my Like criteria to refresh and requery the form,

问题 I'm being driven nuts trying to figure this one out. I'm using Python for the first time, and trying to write data collected from twitter out to an Access 2010 database. The command I'm using is: cursor.execute('''insert into core_data(screen_name,retweet_count) values (?,?,)''', (sname,int(rcount))) The error message being returned is: Traceback (most recent call last): File "C:/Documents and Settings/Administrator/PycharmProjects/clientgauge/tw_scraper.py", line 44, in <module> cursor

问题 While struggling with a single legacy MS Access application I faced this weird error: Cannot open any more databases. The application makes extensive use of UNION sql statements. So this seems to cause access hitting the limit of 2048 open tables. Any other chance than getting rid of these unions? 回答1: I had this problem when using linked external tables. The limit was reached because about 10 excel files were used by different queries over and over again. So the number of open tables was

问题 I was initially very pleased to discover the attachment field in Access 2010. It's a feature that aesthetically irks my inner database purist but my inner lazy sod is in charge here and it does look, on the face of it, like it could make one of my current projects much easier/simpler. Happily it displays pictures/icons automatically on the forms and reports but (why is there always a but eh!) it only displays the first one and I need it to display all of them. You can of course scroll through
