请问怎么控制MessageBox()弹出的对话框的位置？

[liyuhui2007]

例如：我想让一个MessageBox()弹出的对话框在窗体的左下角显示，或右下角，或是窗体的某一个位置

[peterb]

自己做个form实现吧 好像MessageBox()不可以

[taiyangyu119]

不可以，自己写一个吧

[wzytiger]

没用过,好象不可以的,

[liyuhui2007]

自己写一个form怎么弄呀？请给个例子看看呀

[jupiter911]

因为MessageBox本身并不是Form,所以你无法控制他的位置,只能自己写一个窗体了

[GhostAdai]

不可以，自己重写一个。

[jlbaowei]

应该不可以

[lovefootball]

API可以实现
首先用FindWindow找到对话框然后用MoveWindow

[DllImport("user32", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern int MoveWindow(IntPtr hWnd, int x, int y, int w, int h, int repaint);
[DllImport("user32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Auto)]
private extern static IntPtr FindWindow(string lpClassName, string lpWindowName);

与其调用ＡＰＩ还不如自己写个ＦＯＲＭ呢～～～～～～～～

实现起来是比较麻烦，参考如下代码：

using System.Runtime.InteropServices;

public delegate IntPtr HookProc(int nCode, IntPtr wParam, IntPtr lParam);

[DllImport("user32.dll")]
public static extern IntPtr SetWindowsHookEx(int hookid, 
    HookProc pfnhook, IntPtr hinst, int threadid);

[DllImport("user32.dll")]
public static extern IntPtr CallNextHookEx(IntPtr hhook, 
    int code, IntPtr wparam, IntPtr lparam);

[DllImport("kernel32.dll")]
public static extern IntPtr GetModuleHandle(string modName);

[DllImport("user32.dll")]
public static extern bool UnhookWindowsHookEx(IntPtr hhook);

[DllImport("user32.dll")]
public static extern bool GetWindowRect(IntPtr hWnd, ref Rectangle rect);

[DllImport("user32.dll")]
public static extern bool MoveWindow(
    IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

public const int WH_CBT = 5;
public const int HCBT_ACTIVATE = 5;
IntPtr hookHandle = IntPtr.Zero;

private IntPtr CBTHookCallback(int nCode, IntPtr wParam, IntPtr lParam)
{
     switch(nCode)
     {
         case HCBT_ACTIVATE:
             Rectangle vRectangle = new Rectangle();
             GetWindowRect(wParam, ref vRectangle);
             vRectangle.Width = vRectangle.Width - vRectangle.Left;
             vRectangle.Height = vRectangle.Height - vRectangle.Top;
             MoveWindow(wParam,  // 右下
                 Screen.GetWorkingArea(this).Width - vRectangle.Width, 
                 Screen.GetWorkingArea(this).Height - vRectangle.Height,
                 vRectangle.Width, vRectangle.Height, false);
             UnhookWindowsHookEx(hookHandle);
             break;
     }
     return CallNextHookEx(hookHandle, nCode, wParam, lParam);
}

private void button1_Click(object sender, EventArgs e)
{
    hookHandle = SetWindowsHookEx(WH_CBT, new HookProc(CBTHookCallback), 
        GetModuleHandle(null), 0);
    MessageBox.Show("Zswang 路过");
}

我也写了一个，秀一下哈，要不白费了，好在和上面的都不太一样：
[code=C#]

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
nw = new NW();

}
protected override void WndProc(ref Message m)
{

{
if (nw.Handle != null)
{
nw.ReleaseHandle();
}
nw.AssignHandle(m.LParam);
nw.SetPoint(this.Left, this.Top);//显示在窗体的左上角了
}
base.WndProc(ref m);
