600.0. "Using B* API routines from Visual C++ 4.0" by METZFI::SIGNORINI (Mangez des pommes !) Mon May 05 1997 19:23

	Hi,

		I have installed BASEstar Open V3.1 on a ALPHA running 
	Window's NT 3.51. Now, i would like to generate C programs using 
	the BASestar Open API. I am using the MicroSoft Visual C++ 4.0 
	Developer Studio environment to build these programs.

	I have just made up a little program which have to read a data point.
	This program uses the following APIs : 
	bstr_initialize, 
	bstr_reference_set, 
	bstr_data_point_get_value,
	bstr_reference_unset,
	bstr_finish.
	But when i build it, i get the following message for each API routines :
	error LNK2001: unresolved external symbol bstr_...

	Just before the BUILD command, i have initialized the directory path
	to the library files with D:\BSTRO31S\BSTR\LIB

	I think it's probably wrong or it's not enough.

	If someone could help me or give me the location of a Window's NT
	developping guide, it would be very appreciate.
	
	Best regards

	Hi Laurent,
		before going more deeply into your problem, could you please
	check that the reference to the bstr.lib file has been properly set.
	You should look into your developer studio in Build->Setting->Link
	->Object/library modules. Since you have set the library path, you 
	must have there specified the bstr.lib file name.

	Btw, note that B*Open for NT has been built using Visual C++ 4.2
	which is a more stable version of VC++ than V4.0.

	Thank you Maurizio,

	My reference to the bstr.lib file was not correct.
	Now my program works fine.

	Regards
