PRB: Macro with Two SendKeys Actions Loops Infinitely

Article ID: Q103251
Creation Date: 19-AUG-1993
Revision Date: 01-DEC-1996 The information in this article applies to:

  • Microsoft Access versions 1.0, 1.1, 2.0, 7.0, 97

SYMPTOMS


Moderate: Requires basic macro, coding, and interoperability skills.

When you run a macro that includes two SendKeys actions, the macro enters an infinite loop and you must restart your computer to regain control.

CAUSE


When only one SendKeys action is used in a macro, you can stop the macro by pressing CTRL+BREAK and then choosing Halt. However, using a second SendKeys action toggles the default, or non-Single Step, macro mode so that you cannot terminate the macro without restarting your computer.

Steps to Reproduce Behavior


CAUTION: Save all work on your computer before you set up the example below. You will have to restart your computer after you run the sample macro.

  1. Open a database and create the following macro:

          Macro Name       Action
          -------------------------
          Go Loop          SendKeys
                           SendKeys
          Go Loop Actions
          ------------------
          SendKeys
             Keystrokes: " "
             Wait: No
          SendKeys
             Keystrokes: " "
             Wait: No
  2. Create a new, blank form in Design view.
  3. Add a command button to the form and set its OnClick property (or OnPush in version 1.x) to Go Loop.
  4. Switch to Form view, and then click the command button.
