Check a Screen Color Before a Windows Macro Clicks
Asoftech |
A recorded click follows your instructions even when the screen is not ready. If a desktop application has a stable status indicator, a screen color check can help you choose the next action. Asoftech Automation compares a pixel with a reference color and supports different actions for matching and nonmatching results. This guide explains how to test that condition before using it in a routine.
Choose a useful screen indicator
For example, imagine a test application with a solid indicator that turns green when a sample task is ready. Check a point inside that indicator before the next click. This is a suggested workflow, not a built-in integration with that application. Use a large, flat area of color rather than a text edge, animated icon or changing image. A matching pixel is a visual clue; it does not prove that a file was saved or a process completed correctly.
Set up the color check in Advanced Input
Prepare sample data and record a short routine. Open the macro for editing and expand Advanced Input. Place the color check before the click that depends on the indicator. Keep the application visible and the expected screen unobstructed.
Choose whether to check the pixel under the mouse or at a predefined position. For a fixed indicator, select a position inside its solid area. Keep the window layout consistent while testing so the chosen point stays over the indicator.
Select the reference color. The documented color picker can sample the screen; its position option can also fill in the sampled location. Choose Equal for an exact RGB match, Not Equal for a difference, or the approximate comparison for similar colors. Approximate matching can also accept an unintended color, so verify it against both states. For the green-indicator example, use Equal with the sampled green.
Insert the condition. The editor adds If, Else and EndIf lines. Place the test click between If and Else so it runs only when the color matches; leave the Else branch empty for this example. Check that no duplicate dependent click remains after EndIf, where it would run regardless of the result. The Asoftech Automation usage guide explains these controls in more detail.
Test both outcomes before repeating
Run once with the indicator in the expected state and check that only the intended action occurs. Then use the same sample workflow with a nonmatching indicator and confirm that the dependent click does not happen. Repeat with the mouse moved away to check that a hover effect is not changing your sample. If loading takes time, use a suitable Wait action before the check. A single color comparison is not an automatic wait-until-ready routine; repeated checking needs an explicitly designed and tested sequence.
If the color check gives the wrong result
Recheck the sampled point, reference color and comparison mode. A moved window, changed zoom, different theme, tooltip or dialog can put another pixel at the same position. Sample again in the layout you will use. Prefer an exact comparison when the indicator is stable; use approximate comparison only after confirming that it distinguishes the intended states. If no reliable visual indicator exists, leave the decision supervised instead of treating an unrelated color as confirmation.
Keep the condition and the result separate
After each trial, inspect the actual result in the target application. A green pixel cannot validate document contents or detect every application error. Keep the routine small until both paths behave as expected, then back up the tested macro before adding repeats or scheduling.
