推荐答案

设置的="_ blank" title ="New Window"> ^ ]属性
您还应该放置PictureBox的位置，或者使用 FlowLayoutPanel [^ ]

问候

Set Parent[^] property of PDFPicture

You should also position your PictureBox''es or maybe use a FlowLayoutPanel[^]

您从未将图片框添加到表单的Controls集合中.您还需要设置每个图片框的位置"和大小"属性，以使它们不会最终都位于完全相同的位置，并且大小完全相同.它们都具有相同的大小是可以的，只是不要将它们都置于相同的默认坐标(0,0).如果您这样做，只会看到其中一个框.

You never added the picture boxes to the Controls collection of the form. You also need to set the Location and Size properties of each picture box so they don''t all end up being in the exact same place, with the exact same size. It''s OK to have them all the same size, just don''t put them all at the same default coordinates (0,0). You''ll only see one of the boxes if you do.
