C# 全屏模式下,在vlc播放器上覆盖图片盒
我想在Windows窗体应用程序中以全屏模式显示VLC播放器前面的pictureBoxC# 全屏模式下,在vlc播放器上覆盖图片盒,c#,winforms,overlay,vlc,C#,Winforms,Overlay,Vlc,我想在Windows窗体应用程序中以全屏模式显示VLC播放器前面的pictureBox `if(axVLCPlugin21.video.fullscreen == true) { Debug.WriteLine("Is fullscreen"); pictureBox2.BringToFront(); pictureBox2.Focus(); pictureBox2.Show();
`if(axVLCPlugin21.video.fullscreen == true)
{
Debug.WriteLine("Is fullscreen");
pictureBox2.BringToFront();
pictureBox2.Focus();
pictureBox2.Show();
}`
我尝试了这个方法和另一个使用Windows窗体弹出它的方法(),但它只出现在全屏后面
如果有人愿意分享他们的解决方案,我将不胜感激。感谢@Jimi,他建议我使用hook方法,它运行良好,下面是我的代码,希望能帮助他人
public partial class Test : Form
{
private IntPtr testPic;
private IntPtr hWinEventHook;

private WinApi.RECT rect = new WinApi.RECT();

this.Show(toCover);
toCover.Focus();

这是一个太具体的问题,任何人都无法帮助您,而不需要在winforms中显示VLC ActiveX插件,播放视频,然后切换到全屏。当您尝试其他方法时,发生了什么?为什么他们不够好?您是否尝试过创建一个新表单,
form.TopMost=true
,将图片框放在那里?然后会发生什么?@Warty是的,我试过使用from.TopMost=true
但仍然一样,它只出现在全屏后面。这是因为全屏不仅仅是一个无边界窗口,就像游戏劫持整个显示一样…@RonBeyer ya它劫持了整个显示,我找不到任何方法来劫持回来。
