问题 Environment: Windows 7 64bits Runtime Access 2003 32bits Runtime Access 2010 32bits We need to install 2 access runtimes in Windows 7 64bits, versions 2003 and 2010 because we are using databases of these two databases. I updated a pc from a Windows XP that worked out well, and now with this windows 7 there is any way to make this work. It works when I install each of them separately but when they are both installed together, there is no way. The last runtime I install, it is the database

问题 Based on Accessing Password Protected MS Access file from excel, I should be able to go to Options > Client Settings and set the Encryption Method to "Use Legacy Encryption" and then be able to connect to my encrypted database through Excel Data Connections. However, when I do this, I still get prompted for the password repeatedly and eventually have to hit Cancel (and thus get no connection). I am using Excel 2010 and Access 2010. My database is encrypted and has linked tables (as well as

问题 I have a query that looks at two times and calculates the difference and puts the value (in seconds) in another field. I then sort that field. The problem is when one of the times is empty the row in the new field in not populated so when I do the sort the rows that nothing in them are pushed to the top. What I would like to do is replace the null with another value. Something like 9999999. That way when I perform the sort the rows that now have 999999 will be place at the bottom of the sort.

问题 I'm getting an error saying that Access cannot find the referenced form CFRRR but there is definitely a form there. Not sure if I'm just not writing the code correctly. Public Function AssignNullProjects() As Long Dim db As dao.Database Dim rs As dao.Recordset Dim strSQL As String Set db = CurrentDb strSQL = "SELECT CFRRRID, [program], [language] FROM CFRRR WHERE assignedto Is Null" Set rs = db.OpenRecordset(strSQL, dbOpenDynaset) If Not rs.BOF And Not rs.EOF Then While Not rs.EOF strSQL =

问题 I am trying to use an Insert Into query to select data from an Excel file and insert it into an Access table. The issue I'm having is one of the Excel columns can be letters, numbers or both. I would like to select the data as text, but I seem to only get blanks for the text and text/number entries. If I sort the Excel file so that a text item is in the first row, all data is converted. I have tried the following: strSQL = "INSERT INTO tblImport ([TIMS Company Code]) " & _ "SELECT [TIMS

问题 Hi I am creating a table in MS Access to store the details of children in a school. I have a field called YearGroup which needs to calculate the school year they are in based on their date of birth and whether they have been moved up or down a year. I.e. if the expression deems they are six years old they should be placed in year 2. If they were moved down or up a year they should be in year 1 or 3 (this is based on another field in the table called YearModifier). The code I have at the
