ACC: "Out of Stack Memory" Error Message with SendKeys Macro (101067)

SYMPTOMS

When choosing a command button, you may receive the following error message:

Not enough stack memory left

This error message occurs when you activate a macro from the OnPush property in version 1.x, or the OnClick property in version 2.0, of a command button on a form. The macro includes a SendKeys action (in which the keystrokes sent include the ESC key) and the Wait argument is set to Yes.

MORE INFORMATION

You receive the above error message if you choose a command button and all the following conditions are met:

The macro attached to the command button includes a SendKeys action.
The command button's Cancel property is set to Yes.
You choose the command button by pressing ESC.

If the command button activates a macro that performs a SendKeys action, which in turn sends an ESC keystroke, the button that repeatedly activates the macro is chosen and an endless loop results. Note that if the Wait argument on the SendKeys action is set to No, Microsoft Access will appear to hang.

Steps to Reproduce Behavior

Start Microsoft Access and open the sample database NWIND.MDB.

Create a new macro called Test Macro:

        OnPush: Test Macro (version 1.x)
        OnClick: Test Macro (version 2.0)
        Cancel: Yes
