Delphi TWebBrowser 内核版本修改

Delphi TWebBrowser 内核版本修改

WebBrowser的默认内核是IE的

 

改变内核版本的操作：

1、在开始菜单内输入“regedit.exe”，进入注册表编辑器

2、找到注册表项：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

在右侧空白区域内单击鼠标右键，点击[新建]→[DWORD（32-位）值]

新建的项取名为 你的执行文件名称（例如：MyApplication.exe），编辑值时，选择基数“十进制”，填写数值数据，这里填写11000（IE11）

 

 

不同IE版本所对应的DWORD值：

有时间再补充博客，写一个Delphi 版的自动修改代码，以下代码适合Delphi7

 

function TFrom1.WriteAppNameToReg:Boolean;    //写入到注册表
 var
 reg:TRegistry;
 sPath,sAppName:String;
 Sver:string;
 lenver:Integer;
begin
      Result:=True;
      reg:=TRegistry.Create;
    try
        reg.RootKey:=HKEY_LOCAL_MACHINE;
        sPath:='SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION';
        if isWin64 then
        sPath:='SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION';
        if reg.OpenKey(sPath,True) then
        begin
         sAppName:=ExtractFileName(Application.ExeName);
         Sver:=GetIEVersionStr;
　　　　　 lenver:=StrToInt( Copy(Sver,1,Pos('.',Sver)-1) );
         //lenver:=StrToInt(leftstr(Sver, Pos('.',Sver)-1));
         // if not reg.ValueExists(sAppName)then
          if lenver<=7 then
            reg.WriteInteger(sAppName,7000)
          else
          if lenver=8 then
          begin
            reg.WriteInteger(sAppName,8000)
          end
          else
          if lenver=9 then
          begin
            reg.WriteInteger(sAppName,9000)
          end
           else
          if lenver=10 then
          begin
            reg.WriteInteger(sAppName,10000)
          end
           else
          if lenver=11 then
          begin
            reg.WriteInteger(sAppName,11001)
          end;
 
 
        end;
        reg.CloseKey;
         
    finally
       FreeAndNil(reg);
    end;


function TFrom1.GetIEVersionStr: string;   //获取IE版本
var
 Reg: TRegistry; // registry access object
begin
 Result := '';
 Reg := TRegistry.Create;
 try
    Reg.RootKey := Windows.HKEY_LOCAL_MACHINE;
 if Reg.OpenKeyReadOnly('Software\Microsoft\Internet Explorer') then
 begin
  //这儿新版本IE的取值位置不同所以要判断 
  if Reg.ValueExists('svcVersion') then
    Result := Reg.ReadString('svcVersion') 
   else
   if Reg.ValueExists('Version') then
    Result := Reg.ReadString('Version');
 end;
 finally
   Reg.Free;
 end;
end;


function TForm1.IsWin64:Boolean;   // 判断系统
var
 Kernel32Handle:THandle;
 IsWow64Process: function(Handle:Windows.THandle;var Res:Windows.BOOL):Windows.BOOL;stdcall;

  if Kernel32Handle=0 then
     Kernel32Handle:=LoadLibrary('KERNEL32.DLL');
  if Kernel32Handle<>0 then
  begin
    IsWOW64Process:=GetProcAddress(Kernel32Handle,'IsWow64Process');
    GetNativeSystemInfo:=GetProcAddress(Kernel32Handle,'GetNativeSystemInfo');
    if Assigned(IsWow64Process) then
    begin
      IsWow64Process(GetCurrentProcess,isWoW64);
      Result:=isWoW64 and Assigned(GetNativeSystemInfo);
      if Result then
      begin
         GetNativeSystemInfo(SystemInfo);
         Result:=(SystemInfo.wProcessorArchitecture=PROCESSOR_ARCHITECTURE_AMD64)or
         (SystemInfo.wProcessorArchitecture=PROCESSOR_ARCHITECTURE_IA64);
      end;
    end
    else
    Result:=False;
  end
  else
  Result:=False;
end;
