由於要在網頁上顯示Tree的結構,開始使用JQuery的Tree,但是當資料量很大時會導致第一次載入很慢。(特別慢,資料量太大了網頁一下還反映不過來),於是改用JQuery的FileTree的外掛程式,每層通過ajax的方式到後台擷取資料,結果還好,不過當資料量大的時候,頻繁的點擊頁面,反映也會很慢,而且要求Client的配置好些,而這邊的site上帝配置都比較低,有的機器會導致無反映的情況。無奈改用Activex的方式吧。對vc不是特別的熟悉,於是選擇了C#,因為site上的每個Client都會有.net Framework。OK..開始改寫。
主要參考:http://www.codeproject.com/KB/cs/CreateActiveXDotNet.aspx
1.建立類庫工程
2.添加一個UserControl,AxTree
3.定義AxTree Class的屬性
[ProgId("MyTreeActiveX.AxTree")]
[Guid("A5C532BA-45B2-44c7-ACAE-D526EF9D47B0")]
[ComVisible(true)]
[ClassInterface(ClassInterfaceType.AutoDual)]
[ComSourceInterfaces(typeof(ControlEvents))]
public partial class AxTree : UserControl, IObjectSafety
說明:
ComVisible:是否可以見
ComSourceInterfaces:該Activex實現的事件的類
IObjectSafety:繼承與該介面,標記安全,否則在生產Activex後,和網頁互動還需要對ie進行設定。
[
Serializable,
ComVisible(true)
]
public enum ObjectSafetyOptions
{
INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001,
INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002,
INTERFACE_USES_DISPEX = 0x00000004,
INTERFACE_USES_SECURITY_MANAGER = 0x00000008
}
[
ComImport(),
Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"),
InterfaceType(ComInterfaceType.InterfaceIsIUnknown)
]
public interface IObjectSafety
{
[PreserveSig]
long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions);
[PreserveSig]
long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions);
};
4.添加方法,屬性
[ComVisible(true)]
public string Leve1ColorRGB{get..set…}
方法和屬性添加 [ComVisible(true)] 就好
5.添加Event
寫一個Event的介面,ControlEvent
[ComVisible(true)]
[Guid("5F6E5E2D-8C6D-4524-AD44-E8B169D90371")]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface ControlEvents
{
[DispId(0x60020001)]
void OnDial(string callno, string updeppkey);
}
在AxTree中定義對應的Event:
public event ControlEventHandler OnDial;
6.實現IObjectSafety介面
#region [IObjectSafety implementation]
public long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions)
{
pdwSupportedOptions = (int)m_options;
pdwEnabledOptions = (int)m_options;
return 0;
}
public long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions)
{
return 0;
}
#endregion
7.註冊和反註冊 Atviex
[ComRegisterFunction()]
public static void RegisterClass(string key)
{
// Strip off HKEY_CLASSES_ROOT\ from the passed key as I don't need it
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
// Open the CLSID\{guid} key for write access
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
// And create the 'Control' key - this allows it to show up in
// the ActiveX control container
RegistryKey ctrl = k.CreateSubKey("Control");
ctrl.Close();
// Next create the CodeBase entry - needed if not string named and GACced.
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
inprocServer32.Close();
// Finally close the main key
k.Close();
}
[ComUnregisterFunction()]
public static void UnregisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
// Open HKCR\CLSID\{guid} for write access
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
// Delete the 'Control' key, but don't throw an exception if it does not exist
k.DeleteSubKey("Control", false);
// Next open up InprocServer32
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
// And delete the CodeBase key, again not throwing if missing
k.DeleteSubKey("CodeBase", false);
// Finally close the main key
k.Close();
}
8.產生強命名檔案。xxx.snk.編譯產生…ActvieX的dll寫好了。
安裝:
在該解決方案中添加一個安裝項目,選擇項目輸出->主輸出,確認ActiveX的dll檔案的屬性Register:vsdrpCOM,在調整下其他的屬性(檔案名稱..)編譯就好。
cab的安裝製作:
下載cabsdk的工具,微軟網站上有的下。
下載後執行如下:
C:\cabsdk\BIN\MyTreeActiveX>cabarc.exe n TreeActiveX.cab TreeActiveXSetup.msi My
TreeActiveX.inf
Microsoft (R) Cabinet Tool - Version 1.00.0601 (03/18/97)
Copyright (c) Microsoft Corp 1996-1997. All rights reserved.
Creating new cabinet 'TreeActiveX.cab' with compression 'MSZIP':
-- adding TreeActiveXSetup.msi
-- adding MyTreeActiveX.inf
Completed successfully
會產生一個TreeActiveX.cab的檔案,網頁上就可以使用了。
對了。inf的定義:
[version]
signature="$CHICAGO$"
AdvancedINF=2.0
[Setup Hooks]
hook1=hook1
[hook1]
run=msiexec.exe /i "%EXTRACT_DIR%\TreeActiveXSetup.msi" /qn
網頁的寫法:
<object id="ActivexObject" name="ActivexObject" width="100%" height="100%" classid="clsid:A5C532BA-45B2-44c7-ACAE-D526EF9D47B0"></object>
<script language='javascript' for='ActivexObject' event='OnDial(tel,uppkey)'>
dosame…
</script>
通過以上步驟完成ActiveX的編寫,cab的製作和網頁的部分。部署好後,會正常使用。
不過該ActiveX沒有簽名,所有需要設定一下ie,允許下載為簽名的activex才可以正常下載和使用。
如何對ActiveX進行簽名我還不知道,等有時間使用Google大法好好再查查看。
