to li_yirong (lyr): 在你的a.dll工程中找到a.lib文件，将a.dll;a.lib放到需调用该dll工程的debug目录中，system32下也可。在当前vc6的菜单的project->settings->link->object/libaray modules:中将你的a.lib所在地址路径粘贴过来。再重新编译一道，应该可以了。
tools -options-directories,选择directories for lib，指定路径。ok
dynamic-link library (DLL) A feature that allows executable code modules to be loaded on demand and linked at run time. This enables the library-code fields to be updated automatically, transparent to applications, and then unloaded when they are no longer needed. You can use LIB to create an object (.OBJ) file that contains a copy of a member of an existing library. To extract a copy of a member, use the following syntax:LIB library /EXTRACT:member /OUT:objectfileThis command creates an .OBJ file called objectfile that contains a copy of a member of a library. The member name is case sensitive. You can extract only one member in a single command. The /OUT option is required; there is no default output name. If a file called objectfile already exists in the specified directory (or the current directory, if no directory is specified with objectfile), the extracted objectfile replaces the existing file.You can use LIB with the /DEF option to create an import library and an export file. LINK uses the export file to build a program that contains exports (usually a dynamic-link library (DLL)), and it uses the import library to resolve references to those exports in other programs.In most situations, you do not need to use LIB to create your import library. When you link a program (either an executable file or a DLL) that contains exports, LINK automatically creates an import library that describes the exports. Later, when you link a program that references those exports, you specify the import library.However, when a DLL exports to a program that it also imports from, whether directly or indirectly, you must use LIB to create one of the import libraries. When LIB creates an import library, it also creates an export file. You must use the export file when linking one of the DLLs.

只是找不到a.dll而已嘛
好办
把a.dll放到windows目录下的system目录下
或者你把a.dll的绝对路径加到PATH中也行
