libnodave / News: Recent posts

Visual Basic

As many people asked me about VB, I tried it out with Excel 97 and VBA. I had to recompile libnodave.dll with the __stdcall directive. You can find a precompiled .dll, .lib and VBA examples in the "patches" section.

Since version 0.5, libnodave can also be used with win32. The DLL and tesat programs have been compiled succesfully using the free commandline tools from Borland.

libnodave has been tested with an S7-400.
A difference was found in the response in step 10 of PLCconnect. The next version will deal with both. Until then, you can use this patch for S7-400:

uc t7[]={
