• Windows Forms Dynamically loading MDIchild forms at runtime

  Hi all, I would like to create an application where i can easily add / update components (e.g. inventory component, customers component) to the application without modifying the main project. I tried to design the architecture based on a MDI-application where I define the components in MDIchilds. The MDI-parent is then the main project. Each MDI-child has to be registered in a database and subsequently based on a user's credentials, this MDI-child can be loaded. Also based on these credentials, the user menu is dynamically created. I am actually looking for a project similar to DotNetNuke, but then developed in Windows Forms... But th ...Show All

There are software that can run on Thumb Drive like bharat   Oren Novotny wrote: It would be a pretty difficult thing to get .NET programs to run from a USB drive as they require OS level support (the .NET Runtime) to be available.  If .NET is already installed on the host, then you should be able to run most apps from a thumb drive (most apps won't care).  The trick is to have something if .NET is not installed already, and for this you have a couple options -- 1) Include the .NET Framework installer on the USB stic ...Show All
