Delphi 开发ActiveX控件(非ActiveForm)
Delphi 开发ActiveX控件(非ActiveForm)
Q：为什么不采用ActiveForm工程？通过它可以快速开发带窗体控件，创建过程也非常简单(都不用考虑安全接口问题)，很省事！
A：如果要实现的功能用不上窗口，而一个带窗口的空程序就500多KB，不便于ActiveX的发布，本实现方法可降到100多KB，CAB打包后只有几十KB； 好吧，我承认我有点体积控。
2. 在该工程中新建一个 Automation Object对象
填写类名
3.建一个测试方法(Test)
向导会自动生成相关代码！
注意：
如果需要发布到Internet，还需要实现一个IObjectSafety接口，标记脚本是安全的，运行时才不会被IE阻止。如果想在线安装ActiveX控件还需要数字证书签名后才可以。
unit AXDemo_u; {$WARN SYMBOL_PLATFORM OFF} interface uses ComObj, ActiveX, AXDemo_TLB, StdVcl, Windows; type TAXDemoCtrl = class(TAutoObject, IAXDemoCtrl, IObjectSafety) FObjectSafetyFlags: DWORD; { 实现IObjectSafety 接口用于将控件标记为安全，否则IE加载时可能会被阻止！} function GetInterfaceSafetyOptions(const IID: TIID; pdwSupportedOptions, pdwEnabledOptions: PDWORD): HResult; stdcall; function SetInterfaceSafetyOptions(const IID: TIID; dwOptionSetMask, dwEnabledOptions: DWORD): HResult; stdcall; protected procedure Test(const Msg: WideString); safecall; implementation uses ComServ; function TAXDemoCtrl.GetInterfaceSafetyOptions(const IID: TIID; pdwSupportedOptions, pdwEnabledOptions: PDWORD): HResult; var Unk : IUnknown; begin if (pdwSupportedOptions = nil) or (pdwEnabledOptions = nil) then Result := E_POINTER; Result := QueryInterface(IID, Unk); if Result = S_OK then pdwSupportedOptions^ := INTERFACESAFE_FOR_UNTRUSTED_CALLER or INTERFACESAFE_FOR_UNTRUSTED_DATA; pdwEnabledOptions^ := FObjectSafetyFlags and (INTERFACESAFE_FOR_UNTRUSTED_CALLER or INTERFACESAFE_FOR_UNTRUSTED_DATA); pdwSupportedOptions^ := 0; pdwEnabledOptions^ := 0; function TAXDemoCtrl.SetInterfaceSafetyOptions(const IID: TIID; dwOptionSetMask, dwEnabledOptions: DWORD): HResult; var Unk : IUnknown; begin Result := QueryInterface(IID, Unk); if Result <> S_OK then FObjectSafetyFlags := dwEnabledOptions and dwOptionSetMask; procedure TAXDemoCtrl.Test(const Msg: WideString); begin MessageBox(GetActiveWindow, PChar(string(Msg)), initialization TAutoObjectFactory.Create(ComServer, TAXDemoCtrl, Class_AXDemoCtrl, ciMultiInstance, tmApartment);
