    <p>I have the following files</p> <p>file1_moduleA.hpp</p> <p>file1_moduleA.cpp</p> <p>sharedFile.hpp</p> <p>file1_moduleB.cpp</p> <pre><code>//sharedFile.hpp extern CustomClass *doSomething(CustomClass *var1, const char *var2); extern CustomClass *doSomethingElse(const char *var1); template &lt;class MYCLASS_A&gt; void myFunction(CustomClass *var1, const char* var2){ assert(somthing); if (condition){ new (MYCLASS_A); } } //file1_moduleA.cpp #include "sharedFile.hpp" // Contains the definitions of doSomething and doSomethingElse among others //file1_moduleA.hpp // Other declarations //file1_moduleB.cpp #include"sharedFile.hpp" //...SNIPPETS OF CODE void someFunction(CustomClass* var1){ doSomething(var1, "FOO"); } //... </code></pre> <p>The following are in one Visual Studio Project, Project A: file1_moduleA.hpp, file1_moduleA.cpp and sharedFile.hpp</p> <p>The following are in another VS Project, Project B: file1_moduleB.cpp, file1_moduleB.hpp</p> <p>Project A compiles and links perfectly, whereas Project B compiles but gives an unresolved symbol for <strong>CustomClass *doSomething(CustomClass *var1, const char *var2)</strong> at <strong>someFunction in file1_moduleB.cpp</strong></p> <p>I have tried <strong>defining</strong> the function with and without extern; tried using a separate file for the template in file1_moduleA.hpp; tried inducing dependency between ProjectB and ProjectA in VS, but nothing seems to work. I am unsure why the definition is not being found during linking. ProjectA.lib however, is being created.</p> <p>Any help in this regard would be appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
