TestComplete multiple inquiries / issues

For issue 1) rraghvani​  example is a good one. However, these are additional things you can also try:

✅ 1. Standard Scrollbars (Most Common Case)

If the control uses standard Windows scrollbars, TestComplete usually exposes them via the VScroll and HScroll properties.

var wnd = Aliases.MyApp.MainWindow.ScrollableControl;

// Scroll vertically
wnd.VScroll.Pos = 50; // set vertical position
Log.Message("Current vertical scroll position: " + wnd.VScroll.Pos);

// Scroll horizontally
wnd.HScroll.Pos = 30; // set horizontal position

You can also check:

• VScroll.Max, VScroll.Min
• HScroll.Max, HScroll.Min

Use Object Spy to confirm that VScroll and HScroll exist.

✅ 2. Scroll with Keyboard Keys (Fallback)

If the object doesn’t expose scrollbars:

var control = Aliases.MyApp.MainWindow.ScrollableControl;

// Scroll down with arrow key
control.Keys("[Down]");

// Scroll up
control.Keys("[Up]");

// Scroll page down
control.Keys("[PgDn]");

// Scroll to end
control.Keys("[Ctrl+End]");

✅ 3. Scroll with Mouse Wheel

If the control reacts to the mouse wheel:

var control = Aliases.MyApp.MainWindow.ScrollableControl;

// Scroll down
control.MouseWheel(3);

// Scroll up
control.MouseWheel(-3);

✅ 4. Scroll into View (Child Control)

If you want to scroll a child object into view:

var child = Aliases.MyApp.MainWindow.ScrollableControl.SomeChildControl;
child.ScrollIntoView();

⚠️ 5. Custom Scrollbars (Non-standard Controls)

If the control uses custom or owner-drawn scrollbars, you might not see VScroll or HScroll at all. In this case, you’ll need to:

Option A: Click scrollbar arrows or drag manually

var scrollbarDown = Aliases.MyApp.MainWindow.ScrollbarDownButton;
scrollbarDown.Click();

Option B: Drag scrollbar thumb

Use Drag and Drop methods to simulate a drag of the scrollbar thumb:

var thumb = Aliases.MyApp.MainWindow.ScrollbarThumb;
thumb.Drag(thumb.X, thumb.Y, thumb.X, thumb.Y + 100); // scroll down

Use Object Spy to locate these subcomponents (e.g., scroll buttons, thumb).

Ignoring rule "3. One thread per one problem" just this once!

1. You could iterate through the scrollbar positions until the object becomes visible on screen and until scrollbar end position has been reached. Pseudocode code example

   var scrollBar = YourContainerObject.VScroll;
   while (!YourTargetObject.VisibleOnScreen && scrollBar.Position < scrollBar.Max) {
       scrollBar.Position += 10;
       Delay(500); // Allow time to scroll
   }
   YourTargetObject.Click();

    

2.  I don't understand this question. Do you want to perform a Shift Key?

3. Within TestComplete you can have Project Suite, having a number of Projects. You can also set Test Items, to run all the projects it includes. Here's an example, where I run all projects within the project suite, in order

   If you refer to TestComplete Command Line, there are several examples of running TestComplete via the command line shown.

Hi hina​

3. One thread per one problem
Please do not ask several questions in one thread. First of all, they may not be connected to each other. Besides, you will get replies faster if you separate them into different threads posted to the relevant forums.

I am having difficulties replying to any point as I am not an expert on all three subjects.
