Microsoft vba access

If no class module exists for the form or report, Access creates one and adds a procedure to the module for each macro that was associated with the form or report. Access also changes the event properties of the form or report so that they run the new VBA procedures instead of the macros. While the form or report is still open in Design view, if the property sheet is not already displayed, press F4 to display it. On the Event tab of the property sheet, click in any property box that displays [Event Procedure] , and then click the build button.

To view the event properties for a specific control, click the control to select it. To view the event properties for the entire form or report, select Form or Report from the drop-down list at the top of the property sheet.

Access opens the Visual Basic Editor and displays the event procedure in its class module. You can scroll up or down to view any other procedures that are in the same class module. In the Navigation Pane, right-click the macro that you want to convert, and then click Design View. In the Convert Macro dialog box, select the options that you want, and then click Convert. Under Modules , double-click the module Converted Macro- macro name.

Unlike a class module, a standard module is not part of a form or report. You will most likely want to associate the function with an event property on a form, report, or control so that the code runs exactly when and where you want. To do this, either you can copy the VBA code into a class module and then associate it with an event property, or you can make a special call from the event property to the standard module by using the following procedure.

In the Visual Basic Editor, make a note of the function name. For example, if you converted a macro named MyMacro, the function name will be MyMacro. In the Navigation Pane, right-click the form or report with which you want to associate the function, and then click Design View. On the Event tab of the property sheet, click the event property box with which you want to associate the function. Be sure to include the parentheses. In the Navigation Pane, double-click the form or report, and test it to see that the code runs as it should.

From Visual Basic, first create a reference to the Access object library, and then create a new instance of the Application class and point an object variable to it, as in the following example:.

From applications that do not support the New keyword, you can create a new instance of the Application class by using the CreateObject function:. After you create a new instance of the Application class, you can open a database or create a new database by using either the OpenCurrentDatabase method or the NewCurrentDatabase method.

You can then set the properties of the Application object and call its methods. When you return a reference to the CommandBars object by using the CommandBars property of the Application object, you can access all Microsoft Office command bar objects and collections by using this reference. You can also manipulate other Access objects through the Application object. Your code will be faster if you refer to the Controls collection implicitly.

The following examples show two of the ways you might refer to a control named NewData on the form called OrderForm. The next two examples show how you might refer to a control named NewData on a subform ctlSubForm contained in the form called OrderForm. The following example shows how to use TextBox controls to supply date criteria for a query. The following example shows how to use the BeforeUpdate event of a form to require that a value be entered into one control when another control also has data.

The following example shows how to use the OpenArgs property to prevent a form from being opened from the navigation pane. The following table will give you the knowledge of the shortcut keys and their functions available throughout the Visual Basic editor, where you will write , modify and run your VBA code. Code in programming language has to be written exactly, there can be no errors or bugs.

If there is any error or bugs then it will show compiling issue. Fortunately, you can debug code in VBA quickly with these debugging shortcuts. This function is mainly used to change the old path for the linked tables to a new path. The function does this by dropping the linked tables and then relinking it to the same table in the database specified in the new path.

Dim dbs As DAO. Count — 1 To 0 Step -1 If dbs. TableDefs intTbl. Add dbs. Name dbs. Delete dbs. Name End If Next intTbl. Else Debug.
