问题描述

我的工作在C#和.Net4.0在线视频会议项目。

I'm working on online video conferencing project in C# and .Net4.0.

我希望有一个图书馆或code,我可以使用不同的形式收集网络摄像机的图像每秒。我试试这个使用AVICAP32,在此我们在这个发送的邮件像复制或编辑frames.but不同的目的,我们要通过图片框的参考,同时创造处理程序,如下所示:

I want a library or code which I can use for collecting web camera images per second in different form. I try this by using the AVICAP32, in which we send Messages for different purpose like copy or edit frames.but in this we have to pass a reference of picturebox while creating handler as given below:

mCapHwnd = capCreateCaptureWindowA("0", 268435456 | 1073741824, 0, 0, 640, 480,picturebox1.Handle.ToInt32(), 0);

使用这些命令,我​​能够捕捉到的图像,但问题是当我尽量减少PictureBox的形式。当时并没有创造新的形象。

Using these commands I'm able to capture images but the problem comes when I minimize the picturebox form. At that time doesn't create new image.

我觉得这事是因为我最小化的形式,当它直接复制此剪贴板中的图像不显示任何东西。

I think this is happened because I minimize the form and when it copies the image from this clipboard it doesn't show anything.

我怎样才能解决这个问题。任何形式的帮助将AP preciated。

How can i solve this problem . Any type of help will be appreciated.
