I need to pass the pointer of an initialized 1D array of U8 type to my Dll file. At first, I set the length of the 1D array and initialized it. Then I configured the Call Lib Node and made the input parameter as 1D Array Pointer of U8 type. The prototype of the called function in my Dll file is:
EXPORT void Grab(unsigned char *LVPict) Also, I had a goble pointer of 1D buffer in my Dll file, defined as LPBYTE pImage, and I wrote the data in the goble buffer to the 1D array, using for (DWORD i=0; i<dwSize; i++) LVPict[i]=pImage[i]; But after I run the VI, LabView crashed down every time until I reduced dwSize, the legth of buffer, to 1. That means, I can not write anything from the buffer to the array. I'm very very sure the array initialized in LabView is far far huge than the goble buffer.
