如何使表單在手機上可拖動6.5

我正在爲Windows Mobile 6.5（c＃，.net，compact framework）開發應用程序，而且我很難找到如何在不使用的情況下上下拖動表單默認的滾動條。我的表單比設備的屏幕更大，我不希望用戶使用默認滾動條，而是拖動表單。如何使表單在手機上可拖動6.5

任何想法如何做到這一點？

謝謝

窗體無法在Windows Mobile的屏幕上移動。他們也不能只拿到屏幕的一部分。這僅在Windows CE中可能。

Thorsten是正確的，窗體創建是硬編碼到任何Compact Framework運行時，並且您不能創建非全屏窗體（這是一個窗口視圖中的對話框）。

如果您開始在VS（2003/2005/2008）中開發本機C/C++ Windows CE項目，則在您的定義中，窗口大小是免費的。

，但使用的PInvoke改變創建後形式的窗口樣式，你可以有一個可移動的窗口形式：

和應用（下同）窗口樣式和位大小調整後：

這裏是C＃精簡框架的代碼片斷：

using System; 

using System.Collections.Generic; 
using System.Text; 

using System.Runtime.InteropServices; 
using System.Reflection; 

namespace MovableForm 
{ 
    class winapi 
    { 
     public static void moveWindow(System.Windows.Forms.Form form){ 
      SetWindowPos(form.Handle, (IntPtr) HWNDPOS.HWND_TOPMOST, form.Left + 10, form.Top + 10, form.Width - 20, form.Height - 20, (uint)SWP.SWP_SHOWWINDOW); 
     } 

     public static void setStyle(System.Windows.Forms.Form frm) 
     { 
      uint oldStyle = getStyle(frm); 
      uint newStyle = (uint)(
          WINSTYLES.WS_OVERLAPPED | WINSTYLES.WS_POPUP | WINSTYLES.WS_VISIBLE | 
          //WINSTYLES.WS_SYSMENU | // add if you need a X to close 
          WINSTYLES.WS_CAPTION | WINSTYLES.WS_BORDER | //WINSTYLES.WS_DLGFRAME | WINSTYLES.WS_MAXIMIZEBOX | 
          WINSTYLES.WS_POPUPWINDOW); 
      int iRet = SetWindowLong(frm.Handle, (int)GWL.GWL_STYLE, (int)newStyle); 
      //if returned iRet is zero we got an error 

      int newExStyle = GetWindowLong(frm.Handle, (int)GWL.GWL_EXSTYLE); 
      newExStyle = (int)((uint)newExStyle - (uint) WINEXSTYLES.WS_EX_CAPTIONOKBTN); //remove OK button 
      iRet = SetWindowLong(frm.Handle, (int)GWL.GWL_EXSTYLE, (int)newExStyle); 
      moveWindow(frm); 
      frm.Refresh(); 
     } 

     //great stuff by http://ideas.dalezak.ca/2008/11/enumgetvalues-in-compact-framework.html 
     public static IEnumerable<Enum> GetValues(Enum enumeration) 
     { 
      List<Enum> enumerations = new List<Enum>(); 
      foreach (FieldInfo fieldInfo in enumeration.GetType().GetFields(
        BindingFlags.Static | BindingFlags.Public)) 
      { 
       enumerations.Add((Enum)fieldInfo.GetValue(enumeration)); 
      } 
      return enumerations; 
     } 
...

再就是我用枚舉（所有鑄造對不起，我永遠不會明白，爲什麼旗API調用定義爲int）：

 [DllImport("coredll.dll", SetLastError = true)] 
    private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); 
    [DllImport("coredll.dll", SetLastError = true)]

    //non-fullscreen window (ex zDump) = WS_STYLE=0x90c9004, WS_EX_STYLE=0x00000008 
    //WS_POPUP | WS_VISIBLE 
    enum GWL:int{ 
     GWL_STYLE = -16, 
     GWL_EXSTYLE = -20, 
    }

}

...

希望stackoverflow能夠在不久的將來有時間上傳代碼。

基本窗口樣式改變的是WS_CAPTION。〜約瑟夫 – josef
