However your computer can simultaneously process other background tasks like printing or thread ordering.
These functions can be quite useful when you need to hold the program to wait for some other process or task (not directly connected or communicable to the VBA engine) that is yet to be completed.
The syntax of Sleep statement is as follows:#If VBA7 Then Public Declare Ptr Safe Sub Sleep Lib "kernel32" (By Val dw Milliseconds As Long Ptr) 'For 64 Bit Systems #Else Public Declare Sub Sleep Lib "kernel32" (By Val dw Milliseconds as Long) 'For 32 Bit Systems #End If Sub Sleep Test() Msg Box "Execution is started" Sleep 10000 'delay in milliseconds Msg Box "Execution Resumed" End Sub#If VBA7 Then Public Declare Ptr Safe Sub Sleep Lib "kernel32" (By Val dw Milliseconds As Long Ptr) 'For 64 Bit Systems #Else Public Declare Sub Sleep Lib "kernel32" (By Val dw Milliseconds as Long) 'For 32 Bit Systems #End If Sub Sleep Test() On Error Go To Invalid Res Dim i As Integer i = Input Box("Enter the Seconds for which you need to pause the code :") Sleep i * 1000 'delay in milliseconds Msg Box ("Code halted for " & i & " seconds.") Exit Sub Invalid Res: Msg Box "Invalid value" End Sub The job of both of these functions is same but sleep function is not as accurate as Wait.
Sleep statement depends on processor’s ticks to calculate the time delays which many vary slightly on different machines. The advantage of Sleep statement over Wait is that it is quite flexible as you can give the time delays in milliseconds.
