[SOLVED] In LoadRunner what's the difference between ctrx_set_window_ex and ctrx_sync_on

In LoadRunner what's the difference between ctrx_set_window_ex and ctrx_sync_on_window

I am working on a performance test of Citrix application using Load Runner and Citrix Protocol.

I need to wait for a window to appear, and reading the documentation I see I can use one of those:

ctrx_sync_on_window : Waits until a window is created or becomes active.
ctrx_set_window_ex : Waits a specified time for a window to appear in the Citrix client

But reading their documentation, I don't clearly understand the difference except for the time factor and which one I should use.

I tried each of them, and they are working for me, but I don't know which one is the best.

First Option:

ctrx_sync_on_window("Notepad", ACTIVE, 0, 0, 801, 601, "snapshotXX", CTRX_LAST);

Second Option:

// Wait 5 seconds for Notepad popup to appear
ctrx_win_exist("Notepad",5)

Solution

ctrx_win_exist is mostly used, when there is a time frame needed until a windows appears/becomes active; ctrx_sync_on_window is part of the synchronization options, such as bitmap sync. It will make sure the windows is located on a specified position.

Usually it depends on the script which one is better to be used
