Public Shared Function BeginDeferWindowPos(nNumWindows As Integer) As IntPtr

Public Declare Function BeginDeferWindowPos Lib "user32" _

The BeginDeferWindowPos function allocates memory for a multiple-window- position structure and returns the handle to the structure.

DeferWindowPos fills the multiple-window-position structure with information about the target position for one or more windows about to be moved. The EndDeferWindowPos function accepts the handle to this structure and repositions the windows by using the information stored in the structure.

If the system must increase the size of the multiple-window- position structure beyond the initial size specified by the nNumWindows parameter but cannot allocate enough memory to do so, the system fails the entire window positioning sequence (BeginDeferWindowPos
