Body
I am finding some difficulties when I try to iterate with a vector that contains another vector inside. I have a header file which defines a structure like this: typedef struct Set{ char varname[32]; void * value; } Set; <pre><code>typedef struct Setup { float instant; std::vector<Set *> SetVar; } Setup; std::vector<Setup *> TestCase; </code></pre> In the cpp, I have a function that simply reads an xml file and parses the readen value to the TestCase vector, like this: <pre><code>while(SetupHandle.ToElement()){ Setup * newSetup = (Setup *)malloc(sizeof(Setup)); str = SetupHandle.ToElement()->Attribute("instant"); newSetup->instant = atof(str); TiXmlHandle SetHandle = SetupHandle.FirstChild("Set"); i=0; while(SetHandle.ToElement()){ Set * newSet = (Set *)malloc(sizeof(Set)); str = SetHandle.ToElement()->Attribute("Variable"); strcpy(newSet->varname, str); const char * newstr = SetHandle.ToElement()->Attribute("Value"); newSet->value = (void *) newstr; newSetup->SetVar.push_back(newSet); i++; SetHandle = SetupHandle.Child("Set", i); } TestCase.push_back(newSetup); index++; SetupHandle = TC_top.Child("Setup", index); } </code></pre> The library compiles, but when when I use it, the program crashes in the line that says "newSetup->SetVar.push_back(newSet);". It throws an unhandled exception saying: "Unhandled exception at 0x0430d7ba (tcmodule_psttm_isorc2014_d.pyd) in ISORC2014_CaseStudy_d.exe: 0xC0000005: Access violation reading location 0xcdcdcdc1." Does somebody know what am I doing wrong?

1. COIs there a reason why you've written this in such a C-like style? If I were you my first steps here would be to replace malloc with new, and add reasonable constructors to those classes.

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.
