问题 My problem is quite simple but I haven't found a solution so far... I created a form in Access called Form1. In this form, I inserted an "Unbound Object Frame", which is a new macro-enabled Excel worksheet. In the Excel sheet, I create a macro we can call "ExcelMacro". I want to know how to run macros in this Excel sheet from Access, e.g. in my Access macro, run "ExcelMacro" I do NOT want to link my Excel sheet to an external Excel workbook. Do you have any ideas? Thanks a lot for your help!

问题 I have an Access database and an Excel workbook. What I need to do is query the database and paste the query into a worksheet. The issue is Runtime. I have stepped throught the program and everything works, but it works extremely slow, we're talking up to 30 second run times per query, although most of this run time is coming with the CopyFromRecordset call. The database has over 800k rows in the table I'm querying. Currently at my company there are people every morning who manually query the

问题 I have a pretty simple question: Is it possible to order the rows retrieved according to the which condition is met? For example, I have a table of people, and I want to retrieve all people whose names begin with an "I", or end with an "ster", or contain "lo", ordered according to which condition of these is met. First the rows that match the first condition, then the rows that match the second, and so on. ( Without duplicated: if a row meets the first condition, it shouldn't show again for

问题 Is there an easy way to read an entire Access file (.mdb) into a DataSet in .NET (specifically C# or VB)? Or at least to get a list of tables from an access file so that I can loop through it and add them one at a time into a DataSet? 回答1: Thanks for the suggestions. I was able to use those samples to put together this code, which seems to achieve what I'm looking for. Using cn = New OleDbConnection(connectionstring) cn.Open() Dim ds As DataSet = new DataSet() Dim Schema As DataTable = cn

So I'm doing a mock database (so it looks silly) just to learn the ins and outs and need some help with DLookUp at the moment. My database has two tables, with the following fields: C_ID the PK in Courses and FK in Student tblCourse: C_ID, Title, Subject tblStudent: S_ID, C_ID, Name, EnrollDATE As I said this is just for testing/learning. So what I want is to
