Formerly I <a href="https://stackoverflow.com/questions/1863158/message-map-in-win32-no-mfc">asked a question</a> and got a fair response. But I am stucked with below macro definitions. The below definitions generates a Message Map function like it is in MFC Message Map. But the code below does not compile. Whole statements starting with <code>this-></code> are problematic ones except the one in MSG_HANDLER <code>this->meth(msg);</code> dont know why.. Hence what can be done to correct this issue? I use VS 2008. <pre><code>#define MSG_UNPACK(var, id, msg) x##id *var = (x##id *)(msg); #define BEGIN_MSG_MAP \ protected: \ virtual void dispatchToMsgMap(xMessage *msg)\ { \ if (msg->msg.message == WM_NULL) \ { \ return; \ } #define MSG_HANDLER(meth, wm_msg) \ else if (msg->msg.message == wm_msg) \ { \ this->meth(msg); \ return; \ } #define END_MSG_MAP(base) \ else if (msg->msg.message == WM_COMMAND) \ { \ this->dispatchToCmdMap(msg); \ return; \ } \ else if (msg->msg.message == WM_NOTIFY) \ { \ this->dispatchToNotifyMap(msg); \ return; \ } \ \ base::dispatchToMsgMap(msg); \ }; #define BEGIN_CMD_MAP \ virtual void dispatchToCmdMap(xMessage *msg)\ { \ MSG_UNPACK(Cmd, WM_COMMAND, msg); \ \ if (Cmd->ItemID == 0) \ { \ /* not allowed */ \ } #define CMD_HANDLER(meth, cmd_id) \ else if (Cmd->ItemID == cmd_id) \ { \ this->meth(Cmd->ItemID); \ } #define END_CMD_MAP(base) \ else \ { \ base::dispatchToCmdMap(msg); \ } \ }; </code></pre> Here, for example <code>this->dispatchToCmdMap(msg); \</code> is 41st line. 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(41) : error C2059: syntax error : 'this' 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(41) : error C2017: illegal escape sequence 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(42) : error C2059: syntax error : 'return' 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(42) : error C2017: illegal escape sequence 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(43) : error C2059: syntax error : '}' 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(43) : error C2143: syntax error : missing ';' before '}' 1>d:\devel\coding\vs2008\test2\test2\messagemapper.h(43) : error C2059: syntax error : '}'

Guidance

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.
