Namespace: Microsoft.ComputeCluster
Assembly: CcpAPI (in ccpapi.dll)

Usage

Syntax

'Declaration
Function QueueJobs ( _
    jobs As IClusterEnumerable, _
    userName As String, _
    password As String, _
    isConsole As Boolean, _
    hwndParent As Integer _
) As IClusterEnumerable

IClusterEnumerable QueueJobs (
    IClusterEnumerable jobs,
    string userName,
    string password,
    bool isConsole,
    int hwndParent
)

IClusterEnumerable^ QueueJobs (
    IClusterEnumerable^ jobs, 
    String^ userName, 
    String^ password, 
    bool isConsole, 
    int hwndParent
)

IClusterEnumerable QueueJobs (
    IClusterEnumerable jobs, 
    String userName, 
    String password, 
    boolean isConsole, 
    int hwndParent
)

function QueueJobs (
    jobs : IClusterEnumerable, 
    userName : String, 
    password : String, 
    isConsole : boolean, 
    hwndParent : int
) : IClusterEnumerable

Parameters

jobs
An IClusterEnumerable interface that contains a collection of IJob interfaces for the jobs that you want to add to the queue.

userName
The name of the RunAs user, in the form domain\username, under which the job will run. The user name is limited to 80 Unicode characters.

If userName is NULL, empty, or not valid, the cluster searches the calling user's credential cache for the credentials to use. If the cache contains only one credential, that credential is used. If the cache does not exist or contains multiple credentials, the user is prompted for the credentials.

password
The RunAs user's password. The password is limited to 127 Unicode characters. If this parameter is NULL or empty, the method uses the cached credentials (see ICluster.SetCachedCredentials). If the credentials are not cached, the current user is prompted for the credentials. If the isConsole parameter is true, the user is prompted in the console window; otherwise, the standard credentials dialog box is used.

isConsole
Set the value to true if the application is a console-mode application. Set the value to false if the application is a GUI application.

hwndParent
The handle to use as the parent window for the modal credentials dialog box. If 0, HWND_DESKTOP is used. The handle is ignored if isConsole is true.

Return Value

An IClusterEnumerable interface than contains a collection of integers that identify the jobs. The identifiers in this collection correspond directly to the jobs collection passed in the jobs parameter.

Remarks

If you need to add multiple jobs to the queue, calling this method provides better performance than calling the ICluster.QueueJob method in a loop.

If the method fails to add one of the jobs to the scheduling queue, none of the jobs are added to the queue.

Calling this method is the same as calling both the ICluster.AddJobs and ICluster.SubmitJobs methods.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
