[英]How to show modeless owned dialog in .NET 1.1
我需要在.NET 1.1中顯示一個無模式對話框。 以下代碼適用於 .NET 2.0 或更高版本:
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
private static extern IntPtr GetActiveWindow();
private void ShowModelessOwnedDialog()
{
IntPtr wHnd = GetActiveWindow();
NativeWindow parent = NativeWindow.FromHandle(wHnd);
MyForm f = new MyForm();
f.Show(parent);
}
調用Show(IWin32Window)
是在 .NET 2.0 中引入的。 你知道如何欺騙這個代碼在.NET 1.1中工作嗎? 也許有任何非托管電話?
這是 1999 年的一篇文章,展示了如何調用SetWindowLong來完成此操作。 我對您不得不使用 .NET 版本 1 表示哀悼。
這是在 .NET 1.1 中將所有者分配給托管表單的方法。 我從@Dave Markle 答案和 .NET 2.0 的Show(IWin32Window)
實現中提取了以下代碼。
private void AssignOwner()
{
AssignOwner(this, GetActiveWindow());
}
private void AssignOwner(Form f, IntPtr ownerHandle)
{
if (ownerHandle == IntPtr.Zero) return;
NativeWindow parent = NativeWindow.FromHandle(ownerHandle);
GetWindowLong(new HandleRef(f, f.Handle), -8);
SetWindowLong(new HandleRef(f, f.Handle), -8, new HandleRef(parent, ownerHandle));
}
public static IntPtr GetWindowLong(HandleRef hWnd, int nIndex)
{
if (IntPtr.Size == 4)
{
return GetWindowLong32(hWnd, nIndex);
}
return GetWindowLongPtr64(hWnd, nIndex);
}
public static IntPtr SetWindowLong(HandleRef hWnd, int nIndex, HandleRef dwNewLong)
{
if (IntPtr.Size == 4)
{
return SetWindowLongPtr32(hWnd, nIndex, dwNewLong);
}
return SetWindowLongPtr64(hWnd, nIndex, dwNewLong);
}
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
private static extern IntPtr GetActiveWindow();
[DllImport("user32.dll", EntryPoint = "GetWindowLong", CharSet = CharSet.Auto)]
public static extern IntPtr GetWindowLong32(HandleRef hWnd, int nIndex);
[DllImport("user32.dll", EntryPoint = "GetWindowLongPtr", CharSet = CharSet.Auto)]
public static extern IntPtr GetWindowLongPtr64(HandleRef hWnd, int nIndex);
[DllImport("user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto)]
public static extern IntPtr SetWindowLongPtr32(HandleRef hWnd, int nIndex, HandleRef dwNewLong);
[DllImport("user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto)]
public static extern IntPtr SetWindowLongPtr64(HandleRef hWnd, int nIndex, HandleRef dwNewLong);
.net 1.1 中有一個MessageBox.Show 過載和 IWin32Window
http://msdn.microsoft.com/en-us/library/aa335416(v=VS.71).aspx
public static DialogResult Show(
IWin32Window owner,
string text,
string caption,
MessageBoxButtons buttons,
MessageBoxIcon icon,
MessageBoxDefaultButton defaultButton
);
以及在這里獲取 IWin2Window 的示例
