Question

我正在使用Visual Studio Community 2015来修改VB 2013项目。每当我尝试打开我的主Windows窗体时，就会发生“从错误的HRESULT E_FAIL调用COM组件返回”消息。我根本无法修改表格。我可以找到调试中没有代码错误。

如果他们看起来适用于我的情况，我已经尝试了以下几种解决方案： Error HRESULT E_FAIL has been returned from a call to a COM component VS2012 when debugging

这只发生在解决方案中的一个VB表单上。其他两种表格工作正常。

调用堆栈错误：

我要重建表单，因为它只有一个屏幕会出错。目前似乎没有一个很好的解决方案。

获取“错误HRESULT E_FAIL已从调用COM组件返回”VB
