: Woops.. 忘了放说明, Sorry, 如下:<br>: Inpout32.zip contains a DLL that enables direct reading and writing to I/O ports in 32-bit Visual-Basic programs running under Windows 95.<p>: by Jan Axelson<br>: Lakeview Research<br>: Email: jaxelson@lvr.com<br>: WWW: http://www.lvr.com<p>: Important information and cautions:<p>: 1. Use this DLL at your own risk. Writing directly to hardware ports can result in system crashes, loss of data, and even permanent damage. Inpout32 was developed to allow access to parallel ports and other ports on custom hardware, but you can use it to attempt to access any hardware that is mapped as an I/O port. You've been warned!<br>: <br>: 2. Use this DLL only with 32-bit programs. 16-bit programs require a 16-bit DLL (inpout16.dll).<br>: <br>: 3. Windows 95 allows direct port reads and writes unless a VxD has control of the port and blocks access. Under Windows NT, direct port access is not allowed, and you must use a kernel-mode device driver.<br>: <br>: 4. For the latest parallel-port programming and interfacing information and tools, visit Parallel Port Central at: <br>: <br>: http://www.lvr.com <p>: *** <br>: <br>: Inpout32.zip contains the following files:<p>: inpout32.txt<br>: This file<p>: inpout32.dll <br>: A DLL that enables the use of Inp and Out routines in 32-bit Visual Basic 4 and Visual Basic 5 programs. <br>: <br>: inpout32.bas <br>: Visual-Basic declarations for Inp and Out <p>: inpout32.vbp <br>: Visual Basic 4 test project for inpout32. The project will also load into and run under Visual Basic 5.<p>: inpout32.frm <br>: Startup form for the test project <br>: <br>: inpout32.dpr <br>: Source code for inpout32.dll. The DLL was compiled with Borland's Delphi 2.0 Object Pascal compiler.<p>: **<p>
