OemKeyScan

VB聲明

Declare Function OemKeyScan Lib "user32" Alias "OemKeyScan" (ByVal wOemChar As Long) As Long

說明

判斷OEM字符集中的一個(gè)ASCII字符的掃描碼和Shift鍵狀態(tài)

返回值

Long，低字包含了掃描碼。高字包含了下述標(biāo)志：位0標(biāo)志著Shift已經(jīng)按下；位1標(biāo)志著Ctrl鍵按下；位2標(biāo)志著Alt鍵按下。如兩個(gè)字都為-1，表明字符未在OEM字符集中得到定義

參數(shù)表

參數(shù)

類型及說明

wOemChar

Long，欲轉(zhuǎn)換的字符的ASCII值

注解

這個(gè)函數(shù)只能轉(zhuǎn)換那些單擊鍵就能生成的字符。倘若字符要通過“Alt+3數(shù)位”（比如Alt+255）才能出現(xiàn)，則不能用這個(gè)函數(shù)轉(zhuǎn)換

原文：This function only translates keys that can be typed with a single keystroke. Keys that are entered using the ALT + 3 digit entry cannot be converted with this function.
