Copyright

DLL copyright

---

Description:

This is a USBm.dll function that returns a string with DLL copyright information.

Command Syntax:

true⁄false USBm_Copyright( string )

The USBm_Copyright function syntax has these parts:

Remarks:

In VB the string passed as an argument must be large enough to hold all the characters that the function places in the string. The best way to achieve this is to set the string to a large size with the String function as in this code:

strStrng = String(250, ” “)

Note: USBm_Copyright always returns TRUE.

Note: USBm_Copyright does not affect the internal error string.

VB Declaration

Public Declare Function USBm_Copyright _     Lib “USBm.dll” _         (ByVal copyrightstring As String) _     As Integer

VB Example

Dim strng As String * 255     USBm_Copyright strng     frmStatus.lstDevices.AddItem “Copyright of USBm DLL: ” & strng

This code fragment shows that strng is loaded with the “copyright” text of the DLL. Assuming that the form called “Main” exists with a text box called “Info”, the “copyright” information will be made visible to the user.

C Prototype

int USBm_Copyright( char *copyright );

C Example
