WaitStart

Note

This article applies to Visual Studio 2015. If you're looking for the latest Visual Studio documentation, see Visual Studio documentation. We recommend upgrading to the latest version of Visual Studio. Download it here

The WaitStart option causes the VSPerfCmd.exe Start sub-command to return only when the profiler has initialized or when the specified number of seconds has passed. By default, the Start command returns immediately. If the Start sub command returns without initializing the profiler, an error is returned. If the number of seconds is not specified, the Start command waits indefinitely.

The WaitStart option is useful in batch files to insure that profiler has been initialized.

Syntax

VSPerfCmd.exe /Start:Method /Output:FileName[Options] /StartWait[:Seconds]  

Parameters

Seconds
The number of seconds to wait before returning from the Start sub-command.

Required Options

The WaitStart option can only be used with the Start sub-command.

Output: filename
Specifies the output file name.

Remarks

Example

In this batch file example, the Start command will wait for 5 seconds for the profiler to initialize.

VSPerfCmd.exe /Start:Sample /Output:TestApp.exe.vsp /WaitStart:5  
if not %errorlevel% 0 goto :error_tag  
VSPerfCmd.exe /Launch:TestApp.exe  
goto :end  
:error_tag  
@echo Could not start Profiler!  
@echo Error %errorlevel%  
:end
