Delphi 启动应用程序时出现运行时错误 217（断言失败（C:\...\tmssoftware\TMS VCL UI Pack\AdvXPVS.pas，第 1536 行）

Question

从 "TMS ComponentPack" 升级到 "TMS VCL UI Pack" 后，安装在 Windows 7 或 windows 8.1 上的应用程序在启动后崩溃，出现运行时错误 217 错误。

同一应用程序适用于 windows 10 或 windows 服务器 2012

使用 EurekaLog，我可以看到具体错误是在调用过程 LOADDLL

期间第 1536 行的 AdvXPVS.pas 断言失败

我无法调试应用程序，因为我的开发平台安装在 windows 10.

procedure LoadDLL;
begin
  if DLLLoaded then Exit;

  DLLHandle := LoadLibrary('UXTHEME.DLL');
  if DLLHandle >= 32 then
  begin
    DLLLoaded := True;

    @OpenThemeDataForDpi := GetProcAddress(DLLHandle,'OpenThemeDataForDpi');
    Assert(@OpenThemeDataForDpi <> nil);

    //********************************************************* 
    // LINE 1536 START FROM HERE 
    //********************************************************* 
    @OpenThemeData := GetProcAddress(DLLHandle,'OpenThemeData');
    Assert(@OpenThemeData <> nil);

    @CloseThemeData := GetProcAddress(DLLHandle,'CloseThemeData');
    Assert(@CloseThemeData <> nil);

    @DrawThemeBackground := GetProcAddress(DLLHandle,'DrawThemeBackground');
    Assert(@DrawThemeBackground <> nil);


    ...
    ...

    @EnableTheming := GetProcAddress(DLLHandle,'EnableTheming');
    Assert(@EnableTheming <> nil);
  end
  else
  begin
    DLLLoaded := False;
    { Error: UXTHEME.DLL could not be loaded !! }
  end;

end;

有时我们会收到行号减一的错误。在您的情况下，Assert(@OpenThemeDataForDpi <> nil); 失败，因为 OpenThemeDataForDpi 至少需要 Windows 10 1703。作为解决方法，您可以编写自己的版本，它只忽略 dpi 参数并调用标准 OpenThemeData，然后当你得到 nil 指针时，将其设置为你的实现。
