    <p>I have a problem I can't seem to resolve. I have a file JobDispatcher.cpp which includes a file <code>#include "CalculateNormalsJob.h"</code> containing the declaration of a class with the same name.</p> <pre><code>class CalculateNormalsJob : public Job { public: CalculateNormalsJob(some params); ... }; </code></pre> <p>The file CalculateNormalsJob.cpp contains the following definition</p> <pre><code>CalculateNormalsJob::CalculateNormalsJob(some params) : Job(params) { } </code></pre> <p>Both CalculateNormalsJob.h and CalculateNormalsJob.cpp are in the same project and folder as JobDispatcher.cpp which creates a Job object as</p> <pre><code>add(new CalculateNormalsJob(some params)); </code></pre> <p>During linking, I receive the following error</p> <pre><code>Error 9 error LNK2001: unresolved external symbol "public: __thiscall CalculateNormalsJob::CalculateNormalsJob(class ResourceMap *,class JobScheduler *,class Job *,int)" (??0CalculateNormalsJob@@QAE@PAVResourceMap@@PAVJobScheduler@@PAVJob@@H@Z) C:\Fredrik\vs12\proflexa\scanner\JobDispatcherJob.obj </code></pre> <p>I am clueless as to what I have forgotten. I'm using Visual studio 2012 under Win7 and the included v110 compiler.</p> <p>Any help appreciated!</p> <p>EDIT:</p> <p>For some reason it seems like <code>CalculateNormalsJob.cpp</code> is not compiled. I have however no clue as to why. It is included in the project and Visual studio's IntelliSense has knowledge of the class and it's functions. </p> <p>EDIT 2:</p> <pre><code>CalculateNormalsJob.h CalculateNormalsJob(ResourceMap *state, JobScheduler *scheduler, Job* listener, int scanNumber); CalculateNormalsJob.cpp CalculateNormalsJob::CalculateNormalsJob(ResourceMap *state, JobScheduler *scheduler, Job* listener, int scanNumber) : Job(state, scheduler, listener), scanNumber(scanNumber) { } Call: add(new CalculateNormalsJob(state,scheduler,this,scanNbr)); </code></pre>

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.
