问题 Thanks to a great answer to a previous question (thanks Hansup and Remou), I've made an Access form based on a ADODB recordset that pulls at runtime. This enables it to have a checkbox that is only in memory. The checkbox is fine. I've now been asked to add a drop-down filter by "Client" to the form. Easy enough. I made the drop-down box, made a little query for the control source, and in the After_Update event, added this code: Private Sub Combo_PickClient_AfterUpdate() Me.Filter = "Client='

问题 I have an Access form with a textbox that is uses as an expression as it's controlsource to calculate a value to display. While the below expression works fine in Access 2003, it doesn't display in Access 2007 automatically. Only when I click on the field, does the value display. What is does is it checks the database for a value based on other fields on the form. If its NULL, the field displays a "N/A". If it's not NULL, it displays the value found in the database. Does anyone know what I

问题 I'm trying to insert data into a Microsoft Access Database. I inserted data into the Access database, but the first and second time are the only times that show the data I inserted. When I rebuild my application, the data I inserted is gone. I don't know where they go and not show. I use C# with the .NET framework to develop. Here's the relevant part of the code: OleDbConnection con = new OleDbConnection(ConfigurationManager.ConnectionStrings["Constr"].ConnectionString); OleDbCommand com =

问题 I have a database table in Microsoft Access. I want to assign the default value of one of those fields to another field that happens earlier in the same table. I tried the value =[Form1].[AssignedByes] with no luck and the same for =[AssignedByes] but with no luck. Can anyone help? The field name I'm assigning the value to is [RemainingByes] and the field that assigning the value of is [AssignedByes] . 回答1: To get around this problem, I create a Query that basically functions as the table. I

问题 I'm trying to make a field on a report highlight in red with white bold font on a report when it has an "S" populated. This keeps making all records in the field red. Please help! Private Sub Report_Activate() If Me![PULL STATUS] = "S" Then Me![PULL STATUS].BackColor = vbRed Me![PULL STATUS].FontBold = True Me![PULL STATUS].ForeColor = vbWhite End If End Sub 回答1: The code you have should be contained in the On Format event of the Detail section of the report. When you set the BackColor ,

问题 I am encountering a problem, I had done a function that the data can be loaded by detecting scrolling position, the function was made with a SQL statement "Rownum", it only works in Oracle, but not in ACCESS. I would like to query the data and resort it ID value 1 aa 3 bb with Rownum we can do like this NID ID value 1 1 aa 2 3 bb how can I write a SQL statement with Microsoft ACCESS 回答1: Access does not support that function. If your ID field is a numeric primary key, you can include a field

问题 I'm having difficulty getting my pyodbc inserted hyperlinks to work in my Access 2003 database. It appears to look like a hyperlink but does nothing when clicked on. For it to work, I have to edit it in Access and only then does it recognize that, "oh yeah that is a hyperlink". import pyodbc cnxn = pyodbc.connect("DRIVER={Microsoft Access Driver (*.mdb)};DBQ= C:\\Users\\multidata\\Documents\\db1.mdb;") cur = cnxn.cursor() #hyperlink is the text file. table1 is hyperlink column in ms access

问题 Access will sometimes fail to exit cleanly and leave an MSACCESS.EXE process running with no visible user interface (the application is no longer shown in the Applications tab of Task Manager). What is the minimal code necessary to reproduce this error? UPDATE : I've posted an answer that reliably reproduces the problem. I would be very interested in other scenarios that may also reproduce the issue. I will upvote any future answer that successfully reproduces the problem. I would like to
