DataCollection.ResumeProfile Method (ProfileLevel, UInt32)

Article
2015-09-30

The ResumeProfile method decrements the Suspend/Resume counter for the specified profiling level.

Namespace: Microsoft.VisualStudio.Profiler
Assembly: Microsoft.VisualStudio.Profiler (in Microsoft.VisualStudio.Profiler.dll)

Syntax

public static ProfileOperationResult ResumeProfile(
    ProfileLevel profileLevel,
    uint elementId
)

public:
static ProfileOperationResult ResumeProfile(
    ProfileLevel profileLevel,
    unsigned int elementId
)

static member ResumeProfile : 
        profileLevel:ProfileLevel *
        elementId:uint32 -> ProfileOperationResult

Public Shared Function ResumeProfile (
    profileLevel As ProfileLevel,
    elementId As UInteger
) As ProfileOperationResult

Parameters

profileLevel
Type: Microsoft.VisualStudio.Profiler.ProfileLevel

Identifies the execution level of the identifier specified in elementId.

elementId
Type: System.UInt32

The process or thread identifier generated by the system.

Return Value

Type: Microsoft.VisualStudio.Profiler.ProfileOperationResult

The return value, ProfileOperationResult, is an enum.

Remarks

The initial value of the Suspend/Resume counter is 0. Each call to SuspendProfile adds 1 to the Suspend/Resume count; each call to ResumeProfile subtracts 1.

When the Suspend/Resume count is greater than 0, the Suspend/Resume state for the level is OFF. When the count is less than or equal to 0, the Suspend/Resume state is ON.

When the Start/Stop state and the Suspend/Resume state are both ON, the profiling state for the level is ON. For a thread to be profiled, the global, process, and thread level states for the thread must all be ON.

Examples

The following example illustrates the ResumeProfile method. The example assumes that a call to the SuspendProfile method has been made for the same thread or process identified by DataCollection.CurrentId.

void ExerciseResumeProfile()
{
    // The initial value of the Suspend/Resume counter is 0. 
    // Each call to SuspendProfile adds 1 to the Suspend/Resume 
    // count; each call to ResumeProfile subtracts 1. 

    // Variables used to print output.
    HRESULT hResult;
    TCHAR tchBuffer[256];

    // Declare enumeration to hold result of call to ResumeProfile
    PROFILE_COMMAND_STATUS profileResult;

    profileResult = ResumeProfile(
        PROFILE_GLOBALLEVEL,
        PROFILE_CURRENTID);

    // Format and print result.
    LPCTSTR pszFormat = TEXT("%s %d.\0");
    TCHAR* pszTxt = TEXT("ResumeProfile returned");
    hResult = StringCchPrintf(tchBuffer, 256, pszFormat, 
        pszTxt, profileResult);
    }
