Ms Access AddItem with VBA

阅读更多关于 Ms Access AddItem with VBA

I have a Form that has a button on it. The button basically copies records from one Table to the other. As records are read and copied, it is also checked for specific values. E.g. If one of the fields in the table has a value of "" then it should call another form that allows me to enter a date. Once the date is entered and the form is closed the programme carries on with copying. It can also happen that the key fields in the table that is being copied are duplicate. In this case I should a 'listbox form' should be launched with a listbox displaying the values of the duplicate records. I

问题 I have a form to input records to a table. I would like it to open on an empty add (New) instead of displaying the first record of the table. To be used by a Navigation Form which opens the input form from a button. 回答1: You can use acFormAdd (value = 0) as the optional DataMode argument to OpenForm .

filter continuous form using textbox

阅读更多关于 filter continuous form using textbox

问题 I need to let users filter a continuous form using values the user enters into a textbox. And the continuous form is also nested within a couple levels of navigation subforms. This sounds easy enough, but all the examples I find on the web use macros instead of vba. I set up the structure and wrote an AfterUpdate procedure for a textbox txtFilter as follows: Private Sub txtFilter_AfterUpdate() Dim filterval As String filterval = txtFilter.Value With Forms!Main!NavigationSubform.Form

Design an Access Form with Dynamic SQL as Recordsource

阅读更多关于 Design an Access Form with Dynamic SQL as Recordsource

I am pretty new to Access VBA programming. Here is one problem I have when creating a form in Access. I need to link the form's recordsource to a query object which I have already defined. Let's say I have field1, field2, field3, etc. in my query. The end product I would like to present is on top of the form, there are several text boxes for user to input filtering criteria of field1, field2, field3 ... and on a click of a button, a datasheet displays at the bottom of the form with the filtering criteria applied besides the existing fields in my query, I need to include at the end of the

Duplicate each row pulled in and add an extra field counting up one day between a given start and end date

阅读更多关于 Duplicate each row pulled in and add an extra field counting up one day between a given start and end date

I'm using Microsoft Access and I want to create a query that duplicates each row pulled in from a table with an extra field added on counting up one day between a given start and end date. So if there's 4 days between the start and end date there's 4 duplicate rows returned for each record with only difference being the added date field counting up 1 day. Is this actually possible to do? HansUp This task is fairly easy if you have a calendar table which includes a row for each date you need. (See this Stack Overflow answer for other reasons why a calendar table can be useful.) Without such a

Convert Access 2010 accdb to 2007 accdb

阅读更多关于 Convert Access 2010 accdb to 2007 accdb

I'm trying to convert an accdb file from use in Access 2010 to Access 2007. I first tried opening the file with Access 2007 and I get the error Unrecognized database format . I was able to get my backend to open in 2007 by removing the MSysResources table (which uses the new attachment datatype) but the same technique has not worked with my front end. My front end does use a webbrowser control (which Microsoft claims won't work but also won't stop the file form being opened). I thought I'd better import one form at a time to see where the error is. While in a new, blank 2007 file I tried to
