    <p>I need to pass a pointer to a member function as an argument to a member function in another class. What I'm doing is something like below. I want to call int Processor::AddJob(void <em>(</em>_pFunc)(void*), void* _pArg) method with void* ProcessHandler::Task(void* a) as the first argument. I did it as </p> <pre><code>TaskFunc pFunc1 = &amp;ProcessHandler::Task; p_Processor-&gt;AddJob(pFunc1,10); </code></pre> <p>But it gives the error </p> <blockquote> <p>error: no matching function for call to Processor::AddJob(void* (ProcessHandler::<em>&amp;)(void</em>), int)’ Processor.h:47: note: candidates are: int Processor::AddJob(void* (<em>)(void</em>), void*)</p> </blockquote> <p>Can someone please help me on this.My implementation is as follows.(Not the exact code-it is much larger than this)</p> <pre><code>class Processor { public: Processor(); virtual ~Processor(); int AddJob(void *(*_pFunc)(void*), void* _pArg); }; int Processor::AddJob(void *(*_pFunc)(void*), void* _pArg) { //Job addition related code goes here } ///////////////////////////////////////////////////////////////////////////// typedef void* (ProcessHandler::*TaskFunc)(void*); class ProcessHandler { public: ProcessHandler(Processor* _pProcessor); virtual ~ProcessHandler(); void* Task(void* a); void Init(); private: Processor* p_Processor; }; void* ProcessHandler::Task(void* a) { //Task related code goes here } void ProcessHandler::Init() { TaskFunc pFunc1 = &amp;ProcessHandler::Task; p_Processor-&gt;AddJob(pFunc1,10); //This give the compile error. } ///////////////////////////////////////////////////////////////////////// int main() { Processor* pProcessor = new Processor(); ProcessHandler* pProcessHandler = new ProcessHandler(pProcessor); pProcessHandler-&gt;Init(); } </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.
