系统默认浏览器是保存在注册表中,读取和设置需要操作注册表,但是在xp和win7(Vista及以上系统)下的位置是不同的,需要分别读取和设置;
读取系统默认浏览器:
Win7下:
function GetDefExplorerPathOnWin7(): string;
const
CPath = ‘%s\shell\open\command‘;
var
oReg: TRegistry;
sKey, sPath: string;
begin
Result := ‘‘;
sKey := ‘‘;
oReg := TRegistry.Create();
try
oReg.RootKey := HKEY_CURRENT_USER;
if oReg.OpenKeyReadOnly(‘Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice‘) then
begin
sKey := Trim(oReg.ReadString(‘Progid‘));
end;
if not SameText(sKey, ‘‘) then
begin
oReg.CloseKey;
oReg.RootKey := HKEY_CLASSES_ROOT;
sPath := Format(CPath, [sKey]);
if oReg.OpenKeyReadOnly(sPath) then
begin
Result := Trim(oReg.ReadString(‘‘));
end;
end;
finally
oReg.CloseKey;
oReg.Free;
end;
end;
XP系统下:
function GetDefExplorerPathOnXP(): string;
var
oReg: TRegistry;
begin
Result := ‘‘;
oReg := TRegistry.Create();
try
oReg.RootKey := HKEY_CLASSES_ROOT;
if oReg.OpenKeyReadOnly(‘HTTP\shell\open\command‘) then
begin
Result := Trim(oReg.ReadString(‘‘));
end;
finally
oReg.CloseKey;
oReg.Free;
end;
end;
设置系统默认浏览器:
这里假设设置系统默认浏览器为IE,先将IE的路径读取到变量ABrowserPath中;
win7系统下:
procedure SetDefaultBrowerOnWin7();
var
oReg: TRegistry;
begin
oReg := TRegistry.Create();
try
oReg.RootKey := HKEY_CURRENT_USER;
if oReg.OpenKey(‘Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice‘, True) then
begin
oReg.WriteString(‘Progid‘, ‘IE.HTTP‘);
end;
oReg.CloseKey();
finally
oReg.Free;
end;
end;
XP系统下:
procedure SetDefaultBrowerOnXP(const ABrowserPath: string);
var
oReg: TRegistry;
sValue: string;
begin
oReg := TRegistry.Create();
try
oReg.RootKey := HKEY_CLASSES_ROOT;
if oReg.OpenKey(‘HTTP\shell\open\command‘, True) then
begin
sValue := Format(‘"%s" -- "%%1"‘, [ABrowserPath]);
oReg.WriteString(‘‘, sValue);
end;
oReg.CloseKey();
finally
oReg.Free;
end;
end;
