I have an application with 3 forms. Form 1 has a credit card reader control, form 2 uses gps to obtain present coordinates, form 3 has camera to take pictures. Right now I load form1 with 2 buttons on it to go to form 2 and form 3. Issue is each time a form is closed and another is opened, there is significant delay as one control is destroyed and another is created. Can I do something like load all forms at the same time, and then show/hide forms based on what is selected. Would that affect performance as far as memory and resources are concerned?

Hello

to minimize form load delays you should preload forms. There was a similar question at http://www.experts-exchange.com/Programming/Languages/.NET/Visual_CSharp/Q_26729996.html?cid=1131#a34535698. I provided a code sample there.

"Did you already read the article about multiform framework in CF2?

http://msdn.microsoft.com/en-us/library/aa446546.aspx

and the revised one at http://blog.opennetcf.com/ctacke/2009/11/25/RevisitingTheFormStack.aspx"

These articles show how to cache forms. Hopefully these links will suit your needs.
