    <p>I have inherited a Visual Studio project that contains hundreds of files. </p> <p>I would like to extract all the typedefs, structs and unions from each <em>.h/</em>.cpp file and put the results in a file).</p> <p>Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. </p> <p><strong>typdef</strong> int myType;<br> <strong>struct myFirstStruct</strong> { char a; int b;...};<br> <strong>union</strong> Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}<strong>myUnion</strong>;<br> <strong>struct</strong> { bool c; int d;...}<strong>mySecondStruct</strong>; </p> <p>My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this).</p> <p>Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) </p> <p>Or a tool to accomplish this. </p> <p><strong>Edit:</strong><br> I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. </p> <p>The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.</p>

    1. COC++ isn't a regular language, so you won't be able to accurately parse it with a regular expression. Why do you want to do this?

    2. COAnd how would this make it easier to support exactly, when all of your class typedefs and structs are extracted into a non-class related file?

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.
