↘锁芯ラ 提交于 2019-11-27 05:46:05
问题 Bear in mind here, I am not an Access guru. I am proficient with SQL Server and .Net framework.

Well, of course, there is a need to convert the data

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.

不羁岁月 提交于 2019-11-27 04:42:29
问题 I have a list box that populates with different sets of data based on user selections. How can I cycle through any given values that may be in the list box? Is this a For Each statement, or what? 回答1: You can do you a For loop to examine each row in the listbox, and do whatever with the rows which are selected. In this example, I display the second column from selected items in the lstLocations listbox. (Column numbering starts with zero.) Private Sub cmdShowSelections_Click() Dim lngRow As

Use SELECT inside an UPDATE query

自作多情 提交于 2019-11-27 04:32:34
How can I UPDATE a field of a table with the result of a SELECT query in Microsoft Access 2007. Here's the Select Query: SELECT Min(TAX.Tax_Code) AS MinOfTax_Code FROM TAX, FUNCTIONS WHERE (((FUNCTIONS.Func_Pure)<=[Tax_ToPrice]) AND ((FUNCTIONS.Func_Year)=[Tax_Year])) GROUP BY FUNCTIONS.Func_ID; And here's the Update Query: UPDATE FUNCTIONS SET FUNCTIONS.Func_TaxRef = [Result of Select query] Well, it looks like Access can't do aggregates in UPDATE queries. But it can do aggregates in SELECT queries. So create a query with a definition like: SELECT func_id, min(tax_code) as MinOfTax_Code FROM

How to refer to Excel objects in Access VBA?

。_饼干妹妹 提交于 2019-11-26 22:51:40
What declarations I have to make in order to be able to use Excel objects and constants from my Access 2007 VBA script? Dim wb As Workbook or Set objExcelApp = New Excel.Application or .Borders(xlEdgeBottom) Thanks marg First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects. After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example: Dim xlApp as Excel.Application Let's say you added an Excel Workbook Object in your Form and named it xLObject.

梦想的初衷 提交于 2019-11-26 21:49:59
问题 In an MS Access 2007 project report, I have the following (redacted) query: SELECT SomeCol FROM SomeTable The problem is, that SomeCol apparently contains some invisible characters.

I have no control over this data type, so I can't change it. How can I modify my SELECT query to strip out anything non-numeric. I suspect
