Is it possible to use IDiaDataSource::LoadDataFromPdb to read pdbs from symbol store?

Yes, it is possible to use the IDiaDataSource::LoadDataFromPdb method to read Program Database (PDB) files from a symbol store. The symbol store is a location where PDB files are stored along with the corresponding binaries. The LoadDataFromPdb method allows you to load debugging information from PDB files, whether they are located locally or in a symbol store.

Here's how you can use IDiaDataSource::LoadDataFromPdb to read PDB files from a symbol store:

1. Obtain an instance of IDiaDataSource. This interface is used to create and manage IDiaSession and IDiaSymbol instances.

2. Use the IDiaDataSource::LoadDataFromPdb method to load the debugging information from the PDB file in the symbol store. You need to provide the path to the binary executable (EXE or DLL) and the search path for the symbol store.

Here's a code snippet in C++ that demonstrates how to use IDiaDataSource::LoadDataFromPdb to load debugging information from a PDB file in a symbol store:

cppCopy code
#include <windows.h>

#include <dia2.h>



int main() {

    CoInitialize(nullptr);



    IDiaDataSource* pDataSource;

    CoCreateInstance(CLSID_DiaSource,

                     nullptr,

                     CLSCTX_INPROC_SERVER,

                     IID_IDiaDataSource,

                     (void**)&pDataSource);



    // Path to the binary executable

    const wchar_t* exePath = L"path_to_exe.exe";



    // Path to the symbol store

    const wchar_t* symbolPath = L"srv*C:\\Symbols*http://msdl.microsoft.com/download/symbols";



    IDiaSession* pSession;

    if (SUCCEEDED(pDataSource->loadDataFromPdb(exePath))) {

        if (SUCCEEDED(pDataSource->openSession(&pSession))) {

            // Now you can use the IDiaSession instance to access debugging information

            // and symbols from the loaded PDB file in the symbol store.



            pSession->Release();

        }

    }



    pDataSource->Release();

    CoUninitialize();



    return 0;

}

Replace path_to_exe.exe with the actual path to the binary executable and ensure that you have the necessary PDB files in the specified symbol store path.

Note that this example demonstrates how to load debugging information from a PDB file in a symbol store. Depending on your use case, you may need to perform additional operations to retrieve specific debugging information or symbols from the loaded PDB file.
