P: n/a
Hi

I am developing a small application to capture a record a video file
through webcam in C#.NET.
In this application i created a JPEG images for every slide,means every JPEG
image was treated as a slide then i want to display these images as a slide
show.
How can i alot time teo each frame?
How can i display images one by one without my interaction?
Please give me the solution or any releated source code.
Thanks in advance.

Hi,

This might help.

1/ Put a "timer" control on your form (I assume that you're using a form?)
2/ Set the interval (it's in milliseconds)
3/ Set Enabled = true
4/ Handle the 'tick' event. This fires every time the timer passes the
interval. In this tick event, change the picture that you're displaying.

With regards to displaying the picture, I haven't included it in the code
example... I assume that you'd just use a picturebox control.

I have included a code sample which puts a textbox on a form and increments
a counter on it every second.

Hope that this helps,
Damien Sawyer
