所有访客
我在vb.net中的子表单有问题.具有子表单的是不同的Access.
我有3种形式(1是主要形式，2是项目形式，3项目清单)
这是我的过程:

推荐答案

您不能将一种形式放入另一种形式. 表单之间没有功能上的父子关系.

形式上，Form是Control，因此Control.Parent可以用于Forms，但是尝试使一种形式成为另一种形式的父项会引发异常.您可以使用P/Invoked非托管Windows API SetParent来解决问题，但是……不要这样做.防止将表单放入表单是一种很好的防呆措施，请不要滥用此.NET UI库.

相反，只做一种形式.用Control.Parents.Add可以将不同的表单重新制作成面板.一个很好的替代方法是使用TabControl.在这种情况下，您的表单将是TabPages.它易于实现，并且外观和功能非常好.

You cannot put one form insider another. There is no functional parent-child relationship between forms.

Formally, a Form is Control, so Control.Parent could be used for Forms, but an attempt to make one form a parent of another one throws an exception. You can do a dirty work-around by using P/Invoked unmanaged Windows API SetParent, but… don''t do it. The preventions of putting a form into a form is a good fool-proof measure, don''t abuse this .NET UI library.

Instead, make just one form. What were different forms re-work into panels, use Control.Parents.Add. A very good alternative is using TabControl; in this case what were your form will be the TabPages. It''s easy to implement and looks and function in a very nice ways.

Good luck,
