In fact, its own global variables lead to the third-party call stack when it comes out of the core.Be sure to check that your processing is correct.Determines whether the calling interface is thread safe. Let's say you're a colleague. You have to make sure that he is right. Just like today's other core, the caller insists that he writes thread-safe, as if it were not thread-safe, as if the code had not been written, and finally found out that the code he wrote was not thread-safe.

Add a Timer control to the interface, and then add the timer's tick to the UpdatePanel1 trigger (implement a timed partial refresh map), set a time interval, and add the following code to the event: protected void Timer1_Tick (object sender, EventArgs e){/* The following code can realize the dynamic movement of the point, on the basis of the original point longitude offset 0.5 each timeCatalog cat = MapInfo.Engine.Session.Current.Catalog; MapInfo.Data.Table tbl = MapInfo.Engine.Session.Current.C

Operation Steps: 1. Enter the sound will shadow editor, insert a video footage in the video track. 2. Expand the Options panel and set the interval parameter to 15 seconds on the Video tab, as shown in the following figure. 3. Insert a picture of the material in the overlay Rail 1 and adjust the material range. 4. Select the material in the overlay Rail 1 and adjust the material size and position in the preview win
