      VB怎么更改鼠標(biāo)指針樣式

      時(shí)間: 本達(dá)868 分享

        VB設(shè)置鼠標(biāo)的指針樣式,可設(shè)置窗口中的鼠標(biāo)樣式和系統(tǒng)中的鼠標(biāo)指針樣式,通過(guò)操作窗口中的菜單,你就可以很方便的改變鼠標(biāo)樣式,下面是學(xué)習(xí)啦小編給大家整理的一些相關(guān)解決方法步驟,希望對(duì)大家有幫助!

        相關(guān)拓展:vb如何控制鼠標(biāo)

        主要是要通過(guò)兩個(gè)方面:

        (一)對(duì)鼠標(biāo)的停留位置做出判斷,也就是得到鼠標(biāo)在屏幕上停留的位置。

        (二)將鼠標(biāo)的移動(dòng)到所確定的位置上。 而實(shí)現(xiàn)這個(gè)功能則要使用到SetCursorPos這個(gè)函數(shù),此函數(shù)的功能是設(shè)定鼠標(biāo)位置。

        這個(gè)函數(shù)的聲明如下:

        Public Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long

        而僅僅有這個(gè)函數(shù)是不夠的,還需要定義一個(gè)type格式的自定義變量。定義為:

        Public Type POINTAPI

        x As Long

        y As Long

        End Type

        它用于存放鼠標(biāo)的位置(屏幕上的位置)。

        但是一個(gè)新的問(wèn)題又出現(xiàn)了:鼠標(biāo)到底放在哪里呢?也就是如何獲得屏幕上的位置。

        這個(gè)問(wèn)題就要用到另一個(gè)函數(shù):GetCursorPos,它的功能是獲得屏幕上鼠標(biāo)的坐標(biāo)。

        它的聲明如下:

        Public Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

        這樣就可以通過(guò)GetCursorPos函數(shù)獲得鼠標(biāo)的位置,存放到一個(gè)POINTAPI變量中,再通過(guò)SetCursorPos函數(shù)來(lái)設(shè)置鼠標(biāo)的位置。

        這樣就可以十分順利的來(lái)控制鼠標(biāo)了!
