我的 Delphi 项目 (MyProject) 遇到问题。在没有我参与的情况下（一如既往）出现的问题基本上归结为未显示的表格。我检查了 .dpr 文件，它看起来像这样：

// Removed code above for brevity
begin
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TfrmMain, frmMain);
  Application.Run;
end.

我检查了.dfm，表单对我来说看起来不错（我之前从未意识到表单的可见性默认设置是假的，所以我认为就是这样 - 只是发现设置为真可见并没有解决我的问题问题）。

换句话说，我已经检查了我所知道的所有相关设置。所以我创建了一个新的、新鲜的项目（NewProject）。新项目的事件日志如下所示：

我意识到这两个事件日志看起来不一样是有充分理由的，因此这可能充其量是朝着正确方向发展的一点。具体来说，失败的项目 (MyProject) 包含更多库，这会导致加载更多 DLL。

不过，有一件事让我想到：失败的项目在加载 PSAPI.DLL 后停止加载，而工作项目在显示表单之前所做的最后一件事是加载 CLBCatQ.DLL。

这对任何人都意味着什么？我还能做些什么来进一步挖掘问题？谢谢！

经典的 PEBKAC。主表单构造函数有问题，因此没有显示表单。

带回家的信息：不要把一个简单的问题变成一个复杂的问题。
