Interface Nidaq to Softvelocity-Clarion

[Iowa Tinkerer]

Has anyone successfully used nidaq32.dll as an external library in the Softvelocity/Clarion application developement environment? I'm trying to use a PCI66xx board in my app, and having problems with "access violation" crashes in my app when I call the Nidaq dll.

Hello;

I'm not familiar with the environment you mentioned, neither National Instruments supports that, however the NI-DAQ driver is a DLL based driver that allows programming languages that can call standard Microsoft format DLLs to make function calls of that DLL.

Since we didn't test neither try NI-DAQ with that environment, that will be a trial and error process for you.

Sorry if I couldn't be of more help at this time.

I got past the compile and link stage, but when I run the program, it aborts with an "access violation at (address)" error. Am I passing the parameters with the wrong data types? Or looking for the wrong data type returned from nidaq32.dll? Any ideas would be appreciated.
