问题 As the title of my question suggest, how is it possible to loop through all the controls in a form, including subforms. For example I use the below sub routine to set the background colour of controls with the tag * Public Sub colCtrlReq(frm As Form) ' Sets background color for required field -> Tag = * Dim setColour As String setColour = RGB(255, 244, 164) Dim ctl As Control For Each ctl In frm.Controls If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType =

问题 I'm looking to split a multi-page access report up into individual pdf files based on a Customer ID and then saving those pdf files based on the Customer Name (or ID). I've looked into 'printing'/'converting' the report into one massive pdf file and splitting it there, but some customer invoices span two+ pages, therefore splitting that one pdf file page-by-page doesn't work. Any help would be greatly appreciated; if anyone needs more clarification on anything, don't hesitate to let me know.

问题 Is it possible to emulate the following MySQL query: SELECT * FROM `tbl` ORDER BY `date` DESC LIMIT X, 10 (X is a parameter) in MS Access? 回答1: While the Access/JET TOP keyword does not directly provide an OFFSET capability, we can use a clever combination of TOP , a subquery, and a "derived table" to obtain the same result. Here is an example for getting the 10 rows starting from offset 20 in a Person table in ORDER BY Name and Id ... SELECT Person.* FROM Person WHERE Person.Id In ( SELECT

问题 How can I create an Access Database at runtime in C#? 回答1: The first thing you need to do is get a COM reference to the Microsoft ADO Ext. X.X for DDL and Security. The X.X represents whatever version you happen to have on your machine. Mine used to be version 2.7, but with Visual Studio 2008, it was updated to 6.0. alt text http://blog.jrpsoftware.com/content/binary/WindowsLiveWriter/CreateanAccessDatabaseinC_10DDD/AddReference_2.png Once you have added the reference, ADOX will be added to

问题 I want to log web site visits' IP, datetime, client and refferer data to access database but I'm planning to log every days log data in separate tables in example logs for 06.06.2010 will be logged in 2010_06_06 named table.

问题 I've looked quite intensely, but couldn't find a post that directly solves my problem. The following code for a form I created works in Access 2003, which I use at work.

问题 When creating a new database in Access 2007, should ADO (ActiveX Data Objects) or DAO (Data Access Objects) be used? Edit: Part of this database will be importing data from Excel 2007 spreadsheets. 回答1: [For the record, the official name for what once was 'Jet' is now the 'Access database engine'.] For ACE (the Access2007 engine .accdb format) features it has to be ACEDAO. For Jet 4.0 features it has to be ADO classic. For Jet 3.51 features and earlier, pick either ADO or DAO. There are
