I have a .pdb program database from a C++ application compiled in debug on Windows VS2005. I use the DIA SDK to find function names but I can't seem to retrieve the filenames for the symbols.
Is there some switch I need to turn on? Does this work?!
So the answer to this appears to be that you find the line number first and then the source file?!
E.g.
virtual IProgramSymbol^ getSymbolFromAddress(UInt32 address)
{
// Find the symbol with the virtual address we were given
IDiaSymbol ^ sym = nullptr;
m_session->findSymbolByVA( address, SymTagEnum::SymTagFunction, sym );
if (sym != nullptr)
{
// Get source code information via lines numbers. Odd, but this seems to be the way
// to do it.
String ^ srcFile = "unknown";
int line = 0;
UInt64 startAdr = sym->virtualAddress;
// Find line numbers from start_address to start_address+1, which should be 1 symbol!
IDiaEnumLineNumbers ^ lines;
m_session->findLinesByVA(startAdr, 1, lines);
if (lines != nullptr)
{
// get the line number
IDiaLineNumber ^ lnb = lines->Item(0);
line = lnb->lineNumber;
// get the source file from the line number (weird!)
IDiaSourceFile ^ sf = lnb->sourceFile;
if (sf != nullptr)
{
srcFile = sf->fileName;
}
}
return gcnew DiaSymbol(sym, srcFile, line); // found a function
}
