![]() All barcodes require start and stop characters and must be included in the barcode. Self-checking fonts (such as Code 39 and Codabar) have the checking code built-in so that it is not necessary to calculate check characters. Self-checking fonts are easy to use in Access as well as other applications and can be entered directly from the keyboard. It should be noted that if the client is not a technical user or programmer, use the self-checking barcode fonts. Like:ġ23.Implementing barcode solutions with IDAutomation fonts provides a high level of scalability with operating systems, applications and printer independence. One can associate a status line with the progress bar that announces what element is being processed. Pbar.init Me.Progressbar_border, Me.ProgressBar_Bar The progress rectangle in in front of the border. A border, and solid bar that is resized as things progress. Private Sub LogErr(objErr, strMod, strProc, intLine)ĭue to problems with available control I created a home grown progress bar using 2 rectangles.

On your form, all you need is three labels. This produces a nice little progress bar: Just drop it into your project in a class module called clsLblProg, and use it like this: I use it all the time in my Access development projects. In case others might find this useful, here is a class I wrote for this purpose. But you can always show the hour glass this tells the user that something is happening. Possibly you could split the work of your slow query into smaller pieces, in order to get the chance of updating a progress bar. You cannot watch a runnging query in code or the like in Access. Note: Of course you must do the work programmatically for this to work.
