How to get time elapsed in milliseconds

profiling, string, timer, vb6

Solution

Yes, you can use the Win32 API:

DWORD WINAPI GetTickCount(void);

To import it in VB6 declare it like this:

Private Declare Function GetTickCount Lib "kernel32" () As Long

Call it before the operation and after and then calculate the difference in time passed.

Problem

Since performance of string concatenation is quite weak in VB6 I'm testing several StringBuilder implementations. To see how long they're running, I currently use the built-in ``` Timer ``` function which only gives me the number of seconds that have passed after midnight. Is there a way (I guess by importing a system function) to get something with milliseconds precision?
