Use the cstring member function Format for conversion. For example: INTEGER (INT) Str. Format ("% d", I ); Float) Str. Format ("% F", I ); Data Types supported by cstring constructors, such as string pointers (char *), can be directly assigned values. STR = username; V. BSTR, _ bstr_t and ccombstr Ccombstr and _ bstr_t are encapsulation of BSTR, and BSTR is a 32-bit pointer to a string. Char * can be converted to BSTR like this: bstr B = _ com_util: convertstringtobstr ("data"); // you need

pointer to obtain the data address of the safearray, and then assign a value to the value pointed to by the pointer. If an array in safearray is a multi-dimensional array, you can convert the multi-dimensional array to a one-dimensional array, or you can obtain a pointer to the array to operate on the elements in the array. (3) Use the variant variable to wrap the safearray. The source code for implementing a two-dimensional array using safearrar is as follows: Vartype

We can use the system modulation provided by the UNIX system to develop the virtual terminal program, and we can add it to our application. I have written th
