易语言修改在访问完网页后超级链接框中文本的颜色

下面是详细的攻略：

步骤一：获取超链接框的对象

首先，我们需要通过易语言获取到超链接框的对象，可以使用以下代码：

Declare Function GetDlgItem Lib "user32.dll" (ByVal hDlg As Long, ByVal nIDDlgItem As Long) As Long

Dim hSuperLink As Long
hSuperLink = GetDlgItem(hwndDlg, idSuperLink) 'hwndDlg为窗口句柄，idSuperLink为超链接框的控件ID

其中，hwndDlg为窗口句柄，idSuperLink为超链接框的控件ID。

步骤二：获取超链接文本的对象

接下来，我们需要获取超链接文本的对象，可以使用以下代码：

Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hWnd As Long, ByVal Msg As Long, ByVal wParam As Long, lParam As Any) As Long

Dim hSuperLinkText As Long
hSuperLinkText = SendMessage(hSuperLink, WM_GETTEXT, MAX_PATH, ByVal VarPtr(szSuperLinkText)) 'WM_GETTEXT为消息类型，MAX_PATH为字符串缓冲区的长度，szSuperLinkText为缓冲区

其中，WM_GETTEXT为消息类型，MAX_PATH为字符串缓冲区的长度，szSuperLinkText为缓冲区，需要在代码中定义。

步骤三：修改文本颜色

最后，我们需要修改超链接文本的颜色。可以使用以下代码：

Dim hDC As Long
hDC = GetDC(hSuperLinkText)

SetTextColor hDC, RGB(255, 0, 0) '设置文本颜色为红色

ReleaseDC hSuperLinkText, hDC

其中，SetTextColor函数用于设置文本颜色，ReleaseDC函数用于释放设备上下文句柄。

下面是一个完整的示例代码：

'Define Constants
Global Const MAX_PATH = 260
Global Const WM_GETTEXT = &HD

Declare Function GetDlgItem Lib "user32.dll" (ByVal hDlg As Long, ByVal nIDDlgItem As Long) As Long
Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hWnd As Long, ByVal Msg As Long, ByVal wParam As Long, lParam As Any) As Long
Declare Function GetDC Lib "user32.dll" (ByVal hWnd As Long) As Long
Declare Function ReleaseDC Lib "user32.dll" (ByVal hWnd As Long, ByVal hDC As Long) As Long
Declare Function SetTextColor Lib "gdi32.dll" (ByVal hDC As Long, ByVal crColor As Long) As Long

'Define Variables
Dim hwndDlg As Long
Dim idSuperLink As Long
Dim hSuperLink As Long
Dim szSuperLinkText As String * MAX_PATH
Dim hSuperLinkText As Long
Dim hDC As Long

'Get Super Link Control Handle
hwndDlg = GetForegroundWindow() 'Get Handle to Foreground Window
idSuperLink = 1234 'Super Link Control ID
hSuperLink = GetDlgItem(hwndDlg, idSuperLink)

'Get Super Link Text Handle
hSuperLinkText = SendMessage(hSuperLink, WM_GETTEXT, MAX_PATH, ByVal VarPtr(szSuperLinkText))

'Modify Text Color
hDC = GetDC(hSuperLinkText)
SetTextColor hDC, RGB(255, 0, 0) '红色
ReleaseDC hSuperLinkText, hDC

上面的示例代码中通过 GetForegroundWindow 和 GetDlgItem 函数获取了窗口句柄和超链接框的控件 ID，然后通过 SendMessage 函数获取了超链接文本的对象句柄，最后使用 SetTextColor 函数将文本颜色设置为红色。
