你用的WriteLine, Line就是行,所以會加換行符

如果用Sw1.Write("....");就不會換行
在寫System.Windows.Forms.Clipboard.SetText時,提示是依系統,也就是說不一定可使用,鑒于是匿名提問就點到而止
vb.net 有專門的托盤圖標控件 在工具箱里直接添加一個就可以了 兩行代碼即可
NotifyIcon1.Icon?=?Me.Icon
NotifyIcon1.Visible?=?True
在資源文件管理器中,找到數據庫,屬性管理器中出現屬性,選擇不復制,或當文件最新時才復制
這說明你調用 API 傳參存在問題。
首先有沒有設置結構體內存對齊?
[StructLayout(LayoutKind.Sequential)] 加了嗎?
COLORREF 不要用 Color 代替,用 int 代替
TCHAR cfFaceName[32] 定義為 Byte 數組也可以,帶在傳參前,必須初始化為 32 個長度

是不是內存讀寫代碼有問題!用上面的代碼試試,我以前寫的;
調用方法:
Dim mem As New MemoryEditor(進程句柄)
Dim offsets As Integer() = {H1, H2, H3} '{一級基址,二級基址,三級基址}
Dim baseaddr As IntPtr = mem.ReadBaseAddress(內存地址, offsets)
Dim value As Integer = mem.ReadMemoryToInteger(baseaddr)
