problem in picture display

Question

i display a pic on picture box and then i want to display another pic after some seconds
but problem is that first image is not displaying only display 2nd image

1... display first picture from database such as
pbThumbImage.Image = new Bitmap(new MemoryStream(objEmployee.Picture));

2... and then get the reference of current main thread
Thread main = Thread.CurrentThread;
Thread.Sleep(5000);

3.. and then display another pic
pbThumbImage.Image = global::TimeEntrySystem.Properties.Resources.DefaultImage;

but problem is that first image is not displaying only display 2nd image

you are only seeing the second image because you are using the UI thread to do the showing of the image. You see the UI thread will not update the form until ALL of the code has been completed. you can get around this by using a Timer control. Put the timer control on the form set it's interval to 5000 and set Enabled = FALSE . now in your current code instead of doing a Thread.Sleep(5000);(also remove the other thread code) enable the timer. Double click on the timer to create the Tick event. In the Tick event copy your code to display the second image. your code would like something like this... private void Form1_Load(object sender EventArgs e) { pbThumbImage.Image = new Bitmap(new MemoryStream(objEmployee.Picture)); timer.Enabled = true; } private void timer_Tick(object sender EventArgs e) { timer.Enabled = false; pbThumbImage.Image = global::TimeEntrySystem.Properties.Resources.DefaultImage; }
