cursor

问题 I am using JavaScript to create a very simple code that inserts bulletin board codes into a textarea when you click on a button. The code I wrote works ok, however, I would like to be able to place the new tags at the cursor instead of at the end of the text, and then keep the cursor in the middle of the new tags.

A blinking cursor seems weird in a view that can't be manipulated

问题 I am trying to write a procedure with the following functionality. Namely, is looking for records from the tables in the schema. In particular, it is a typepkstring column in these tables. At the same time, I have the composedtypes table on the same schema, which has the column pk. The pk column contains all number identifiers from the aforementioned typepkstring column.

问题 When I open the Google web page using: WebBrowser1.Navigate('http://www.google.com.au/advanced_search?hl=en'); it opens with the cursor in the edit box.
