A source control plug-in built using the Source Control Plug-in API Version 1.2, can use a batch operation to execute the same source control operation across multiple projects or multiple connection contexts. Batches can be used to eliminate redundant, per-project dialog boxes from the user experience.
If a user selects multiple items that belong to more than one connection in a source control plug-in built using the Source Control Plug-in API Version 1.1 (for example, two web projects on different file-share machines) and checks them out, the user sees the same dialog box repeatedly. This scenario occurs even if the user clicks the Apply to All check box in the dialog box, because the IDE resets its state for each connection context.
New capability flag
The SccBeginBatch function sets the SCC_CAP_BATCH flag to indicate that a batch operation is in progress.
New functions
The following new functions support the batch operation:
The SCCBeginBatch function starts a group of source control operations. The SccEndBatch function closes the group. The groups may not be nested.
