Earlier in this chapter you used the Save and SaveAs methods of the ThisWorkbook property to save the files you change using VBA. Excel keeps track of whether a workbook has unsaved changes, which is helpful if you want to check the workbook and save it every time you run a procedure that affects the workbook s contents, or if you want to close a workbook without saving any of the changes you ve made (such as when you run a series of formatting routines to highlight different aspects of your data but want everything reset when you re done).

Another aspect of saving values in a workbook relates to how extensively you use links to external data sources. For example, if you were part of an enterprise that made a lot of individual sales that you tracked in a Microsoft Access database, you might want to create links from each cell in the workbook to the corresponding cell in the database table. If you had Excel continue its default behavior of recalculating the workbook by checking the values in the database table, you could have a long wait on your hands every time you open the workbook. The code you use to save the link values is 23 22 Setting the SaveLinkValues property to False would cause Excel to re-check the values every time the workbook is opened and, if the values were not available, would generate an error. 23 23 Private Sub ProductName_GotFocus() We have some tricky "overlay" text boxes here that shouldn t get the focus.

It also keeps the unbound combo box in sync as you move from row to row as long as the underlying record has a valid category. (A new record won t have a related CategoryDescription until you choose a Product ID, so the code doesn t update the unbound combo box on a new record.) Finally, if you try to click in CategoryDescription or ProductName, the GotFocus code moves you to the underlying combo box where you belong. Why didn t I simply set the Enabled property for CategoryDescription and ProductName to Yes If you do that, then you can t ever click into the category or product combo boxes because the disabled text box overlaid on top would block you. Note If you want to see what the filtered combo box looks like without the overlay, make a backup copy of Contacts.mdb, open the fsubContactProducts form in Design view, move the Category Description and Product Name text boxes down similar to Figure 23-19, and save the form. Now open the frmContacts form and click on the Products tab. winforms qr code reader WinForm Barcode Reader with Webcam and C# - Code Pool
