BINDSPEED
Fields
| Name | Value | Description |
|---|---|---|
| BINDSPEED_INDEFINITE | 1 | The IOleItemContainer::GetObject operation must be completed in a moderate amount of time. If this flag is specified, the implementation of IOleItemContainer::GetObject should return MK_E_EXCEEEDEDDEADLINE unless the object is one of the following: |
| BINDSPEED_MODERATE | 2 | The caller will wait only a short time. In this case, IOleItemContainer::GetObject should return MK_E_EXCEEEDEDDEADLINE unless the object is already in the running state or is a pseudo-object. |
| BINDSPEED_IMMEDIATE | 3 | There is no time limit on the binding operation. |
Remarks
Callers of the IOleItemContainer::GetObject method specify values from this enumeration, and implementers of that method use these values as a guideline for how quickly they must complete their operation.
The system-supplied item moniker implementation is the primary caller of IOleItemContainer::GetObject. The BINDSPEED value that it specifies depends on the deadline specified by the caller of the moniker operation.
The deadline is stored in the dwTickCountDeadline field of the <xref:Microsoft.VisualStudio.OLE.Interop.BIND_OPTS> structure in the bind context passed to the moniker operation. This value is based on the return value of the GetTickCount function. If dwTickCountDeadline is zero, indicating no deadline, the item moniker implementation specifies BINDSPEED_INDEFINITE. (This is the default dwTickCountDeadline value for a bind context returned by the CreateBindCtx function.) If the difference between dwTickCountDeadline and the value returned by the GetTickCount function is greater than 2500, the item moniker implementation specifies BINDSPEED_MODERATE. If the difference is less than 2500, the item moniker implementation specifies BINDSPEED_IMMEDIATE.
Implementations of IOleItemContainer::GetObject can use the BINDSPEED value as a shortcut approximation of the binding deadline, or they can use the IBindCtx instance parameter to determine the exact deadline.
