Generic Progress Bar - for long-running events (queries, etc.)

I have a few long-running events in my application (example:  building a 10-level treeview structure from 10 data tables.  Over our network, this task can take as long as 10-15 seconds to build for some conditions (which feels like an eternity) - I have played with indexing, with only minor improvement.  When run locally, from my disk, the tasks run much faster.

The only indication to the user that something is happening is the status bar at the bottom of the Access window, which is pretty dinky and not-so-obvious, and the hourglass.

I'd like to add a generic progress bar (or a pop-up) that would more clearly indicate that *something* is happening, and maybe describe the task.  I've seen similar things in other apps that run, but % progress is unknown (i.e., a repeatedly scrolling progress bar).

As the processes that are running are fairly CPU intensive, I do not want to add any significant burden or drag out execution time by any appreciable amount.

Any ideas how to present something to the user?

u can use SysCmd to do it

an example can be found here

when u build, its obviously in a loop

so see if u can build around that
Define a counter, though u really need to know the MaxValue, I guess a large dummy value would suffice if u dont knw

so to initialize the progress bar, setting explaining text and maximum value for the counter

Call SysCmd(SysCmd_InitMeter, "Text", MaxValue)

Setting the Progress bar using the counter value - increment countervalue in loop, remeber also to do  DoEvents

Call SysCmd(SysCmd_UpdateMeter, CounterValue)

then when done remove the progress bar when finished

Call SysCmd(SysCmd_RemoveMeter)
The other option is to create a popup form

then in your counter, update the value or something in the popupform
then refresh that form

Docmd.openform "myPopup"

do ... loop here

    do somethng
    forms!mypopup!counter = somevalue

Hello markp99

Since you have nothing to display in way of progress, what you are really looking for is an animation.

An animated gif on a popup form would be ideal, but I can't seem to display animations on forms. You would have to build the form with WinAPI calls (much like the "copy file" animation).

In pure access, you would use a popup form with a timer event, for example set to run two or three times a second. In that event, you can manipulate the size of a rectangle, move something around on your form, or even create a crude animation using image objects (for example six hidden images, and your timer event will show them one at a time).

The good thing about the timer event is that every thing happens almost as if it ran in a separate thread. The bad thing is the "almost". Some operations take too high a priority and even prevent the timer of a form to do any animation, and the screen won't refresh.

But it's worth a trial.


I have used the following below as reference to help me use a popup form to track the progress of an FTP download and Db data refresh.  It is not pretty, but it worked.  But, I wouold go with Mr. Harfang concepts, they have helped me in the past.

1. Go to MVP Sandra Daigle's site for some working examples:
