问题 Here is a code snippet: Private Sub frmSearch_UnMarkAll() Const sqlD As String = "DELETE * FROM PickList WHERE TableName = ""CARS"" AND KeyNo IN (" & _ "SELECT RecNo FROM Cars " If frmSearch.WhereSql <> vbNullString Then CurrentDb.Execute sqlD & frmSearch.WhereSql & ")" End If Stop End Sub This function is called by clicking a command button on the frmSearch form. The button raises an event that is handled by the above code. WhereSql is the where clause from the listbox displayed on the find

问题 I'm reading an excel file from a C# app using ACE.OLEDB. Everything has worked fine so far until today I noticed that one of the column names is read incorrectly. Here's what I've got in my excel file Here's what I've got in my debugger Basically the dot (".") is replaced with a hash ("#") for some reason. The code is straightforward and works fine for the most part, don't think the problem is there, but will show it here just for the sake of clarity. DataTable data = new DataTable(); string

In comes Access, and as soon as you open the linked table, Access shows a 0 (false) instead of a blank cell (problem

问题 I am trying to extract the schema of an .mdb database, so that I can recreate the database elsewhere. How can I pull off something like this? 回答1: It is possible to do a little with VBA. For example, here is a start on creating script for a database with local tables. Dim db As Database Dim tdf As TableDef Dim fld As DAO.Field Dim ndx As DAO.Index Dim strSQL As String Dim strFlds As String Dim strCn As String Dim fs, f Set db = CurrentDb Set fs = CreateObject("Scripting.FileSystemObject") Set

问题 For a small project I need to utilize a simple database with very light requirements: few tables, no more than few thousands of records in total, 2 or 3 users. I am working in .NET environment. As a database server (even those Express editions) seems like a huge overkill in this case, a very simple MDB database could do for most of the requirements. I am however, concerned about concurrency. My idea is to place the .mdb file on a network share and let users access this file from their .NET
