问题 I found many questions similar to mine but not quite the same, and nothing I found in them helped me so here is new one. Expected output: Difference between one time record and previous one if the User is the same. Sample table: +-------+--------+-------------------+------+ | RowID | User | Godzina_transakcji| Diff | +-------+--------+-------------------+------+ | 1 | AAA | 14:23:03 | | | 2 | AAA | 14:23:57 | | | 3 | AAA | 14:25:03 | | | 4 | BBB | 03:37:23 | | | 5 | BBB | 03:39:21 | | | 6 |

问题 I would like to be able to change the Textbox.DefaultValue during the 'On Load' event of a form such that each time the form is loaded the user is prompted with an InputBox to change a specific TextBox.Default value which in my case the TextBox control on the table is called Stream. I have tried the following code but each time it gives me a 'RunTime Error 3422 Cannot modify table structure. Another user has the table open'. Private Sub Form_Load() CurrentDb.TableDefs("Class 1 Students (C1)")

问题 I have a report that lists Deposits, with the DepositID set as a hyperlink. OnClick of DepositID, it opens the Deposit Entry form to that particular record. However, the form opens to a new record instead of the one the user clicks on. I think it is because I have another bit of code that runs OnLoad of the form that goes to a new record, and it might be executing that after executing the OnClick code. OnClick of DepositID from the report: DoCmd.OpenForm "DepositForm", acNormal, "", "

问题 I've created a form where I can use a subform to load data from a query into textboxes so I can edit the data one at a time and update the database. This usually works fine except I have a run time error that randomly appears now and then - '-2147352567 (80020009)': The value you entered isn't valid for this field.' If I stop running it and try running it again it usually works fine until the same run-time error appears. It's very inconsistent. Private Sub btn_SelectAgency_Click() If Not (Me

问题 We have developed a consolidation function that will be used by other processes and want to position the function in its own MDB (call it "remote") so that it can be referenced and called from "caller.mdb" when its needed. The function is designed to return an array and works great when executed called directly from within "remote." However, with "remote" properly referenced in the "caller" VBA project, when "caller" makes the call the function returns errors. We get a variety of errors such

问题 I'm having a little trouble with the form filter in Access 2007. I'm using the listview in a few forms and the user needs to be able to filter there. For testing purposes I made a query, which is just based on one table. If I want to set the first filter, it looks like that: I choose a value and if I want to set another filter (on a different field obviously), there aren't values available to choose from. This seems to happen only if I use a query (doesn't matter if I use every field, or just
