问题 I have an export process that transfers data from my Access tables to an Excel File. A couple times I have had issues where the process didn't generate one or more of the sheets (1 sheet = 1 table) in Excel. So when the transfers are complete I want Access to check if all the sheets are located in the Excel file. I have most of the Check process worked out all I need now is a way to "read" the sheet names from the Excel File in to a table. How can I read the Sheet name (not the data)? 回答1:

问题 I am importing an excel file into Access 2010 and the date field(CALLDATE) comes in as text(YYYYMMDD). I would like to use an update query to update a new field "dateofcall" but using a date/time format.

I also tried to use DateSerriel() but still was getting errors. Any suggestions? 回答1: You can use left, right and

问题 I have a form that has the 'data entry' property set to yes. It is bound to a table. When I start filling in the form it automatically saves it. I do not want this to happen.

So how to can I save meaning RichTextBox content in the Access database in RTF format? And how to can I read this? 回答1: Native Rich text in Access 2007/2010/2013 uses a subset of HTML, not RTF, so unless you want to convert to/from RTF<>HTML when you load/save your data, you will have to find another way to store your formatted text.

问题 So this code is meant to serve as a simple search system to go to certain records in a recordset. I originally had it so they had to click the btnGoToID button in order to perform the search.

问题 Is there a limit to the amount of inserts you can do within an Access transaction before you need to commit or before Access/Jet throws an error?

问题 I'm creating a windows application using C# whereby I'm accessing an empty Access database which contains two tables: Provinces and Locations. I'm working on the form that just deals with the Provinces table which looks like this: This is a subform.
