This registered interface allows the session debug manager (SDM) to obtain information about programs that have been "published" through the IDebugProgramPublisher2 interface.

Syntax

IDebugProgramProvider2 : IUnknown

Notes for Implementers

The debug engine (DE) implements this interface to provide information about programs being debugged. This interface is registered in the DE section of the registry using the metric metricProgramProvider, as described in SDK Helpers for Debugging.

Notes for Callers

Call COM's CoCreateInstance function with the CLSID of the program provider that is obtained from the registry. See the Example.

Methods in Vtable order

Method Description
GetProviderProcessData Obtains information about programs running, filtered in a variety of ways.
GetProviderProgramNode Gets a program node, given a specific process ID.
WatchForProviderEvents Establishes a callback to watch for provider events associated with specific kinds of processes.
SetLocale Establishes a locale for any language-specific resources needed by the DE.

Remarks

Normally, a process uses this interface to find out about the programs running in that process.

Requirements

Header: msdbg.h

Namespace: Microsoft.VisualStudio.Debugger.Interop

Assembly: Microsoft.VisualStudio.Debugger.Interop.dll

Example

IDebugProgramProvider2 *GetProgramProvider(GUID *pDebugEngineGuid)
{
    // This is typically defined globally. For this example, it is
    // defined here.
    static const WCHAR strRegistrationRoot[] = L"Software\\Microsoft\\VisualStudio\\8.0Exp";
    IDebugProgramProvider2 *pProvider = NULL;
    if (pDebugEngineGuid != NULL) {
        CLSID clsidProvider = { 0 };
        ::GetMetric(NULL,
                    metrictypeEngine,
                    *pDebugEngineGuid,
                    metricProgramProvider,
                    &clsidProvider,
                    strRegistrationRoot);
        if (!IsEqualGUID(clsidProvider,GUID_NULL)) {
            CComPtr<IDebugProgramProvider2> spProgramProvider;
            spProgramProvider.CoCreateInstance(clsidProvider);
            if (spProgramProvider != NULL) {
                pProvider = spProgramProvider.Detach();
            }
        }
    }
    return(pProvider);
}
