I have a form ,by invoking mouse_click event,i captured mouse clicked point and stored in 'mpoint' variable.now i have a second form,so my question is how i invoke mouse_click event of first form so that i can use 'mpoint' value in second form

推荐答案

你需要做的确切取决于两种形式之间的关系。如果表单创建了另一个的实例，则将其命名为Parent，将新表单称为Child。现在因为父母知道孩子（它必须要创建实例），但孩子不需要知道父母，你想要做什么取决于你的两个表格之间的关系。

在两种形式之间传递信息，第2部分：儿童到父母 [ ^ ]

Exactly what you need to do depends on the "relationship" between the two forms. If a form creates an instance of the other, call it the "Parent" and new form it's "Child". Now because the parent knows about the child (it has to in order to create the instance), but the child needn't know about the parent, exactly what you want to do depends on teh relationship between your two forms.

See here:
