问题 I'm inserting a few rows in a table via OleDB, and select instantly the inserted row. I can't retrieve the row in this way, i have to wait for approx. 3-5 seconds. And then the inserted row appears in the table. I observed this behavior in the database itself, i inserted the row via OleDB and watched the opened table in Access. The row appeared 3-5 seconds later in the table. Does Access buffer rows? Do i have to send a flush or commit, etc. via OleDB ? Any suggestions would be very helpful.

问题 I am attempting to export a worksheet from Excel 2007 to Access 2007 on Windows 7 including creating a new table. I have tried the following VBA in Excel but it states "Compile Error User-defined types not defined" and then highlights the first variable declaration for the Access object. I have the Microsoft ActiveX Data Objects 6.1 Library referenced. What is wrong? Dim acc As New Access.Application Dim ws As Worksheet Dim ThisWorkbook As Workbook Dim a As Long Dim b As Long Set ThisWorkbook

问题 I'm new to VBA and Access in general and ran into this problem whilst trying to use the proposed alternate implementation from another question I'd asked (DLookup in Access not running until textBox clicked on in Form) The code below runs, the issue is that Me.Key is different for each record being displayed in the form and running this in the form open event means it grabs only the first value assigned to Me.Key from the first record. How can i make this run so that Me.Key is different for

问题 I have two tables in an Access database, tblProducts and tblProductGroups. I am trying to run a query that joins both of these tables, and brings back a single record for each product. The problem is that the current design allows for a product to be listed in the tblProductGroups table more than 1 - i.e. a product can be a member of more than one group (i didnt design this!) The query is this: select tblProducts.intID, tblProducts.strTitle, tblProductGroups.intGroup from tblProducts inner

问题 I have 20 text boxes on an Access 2010 form called [P101] to [P110] which refers to fields [P101] to [P110] in the source table. The may contain a value or not, but if not I do not want to see them. I also have a field [UsedFields] in the table which has counted how many of the fields are in use. In Form_Current I can set the following code but is there a way I could set a FOR NEXT loop to use a variable for the Field Name? The current code (which works but is very clumsy) is: If UsedFields >

问题 When I try to run this query in Access through the ODBC interface into a MySQL database I get an "Expression too complex in query expression" error. The essential thing I'm trying to do is translate abbreviated names of languages into their full body English counterparts. I was curious if there was some way to "trick" access into thinking the expression is smaller with sub queries, or if someone else had a better idea of how to solve this problem. I thought about making a temporary table and

问题 Does an end-user need to own MS-Access application to run an C#.Net application that uses MS-Access? The C# custom application will ship with MS-Access File (.Accdb). The application is expected to access tables and show reports. I expect the user to be able to download and install the run-time version of MS-Access (free) (and) OLEDB driver, then install the C# application. User may have to adjust the connection string, but I am not sure if doing just this is sufficient or not. Thanks. 回答1:
