LockType Enumeration (original) (raw)
Summary
Defines the various flags that can be used to lock and unlock Multimedia features.
Note
As of v21 the LEADTOOLS Multimedia toolkit has been updated to use a seamless license mechanism and any new development must use it. The new licensing mechanism uses RasterSupport.SetLicense. For a step-by-step tutorial on a .NET platform, refer to Add References and Set a License.
The UnlockModule mechanism is still supported in v21.
Syntax
public enum class LockType Members
| Value | Member | Description |
|---|---|---|
| 0x00000001 | Computer | Unlocks the module at the computer level. Unlocking at the computer level should be avoided because it can cause unexpected behavior in other applications. |
| 0x00000002 | Application | Unlocks the module for this instance of the application. This is the recommended value. |
| 0x00000004 | ApplicationPath | Unlocks the module for this particular application. Use this for unlocking support in a third party application (like Windows Media Player). |
Example
using Leadtools;
using Leadtools.Multimedia;
using LeadtoolsMultimediaExamples.Fixtures;
public bool _result = false;
public void MultimediaSupportExample()
{
// pszKey is a string containing the serial number. It is defined like this:
// string pszKey = "MySerial";
string pszAppId = "My Test Application";
try
{
// unlock the multimedia feature
Leadtools.Multimedia.Common.MultimediaSupport.UnlockModule(pszKey,
Leadtools.Multimedia.Common.LockType.Application,
pszAppId);
}
catch
{
return;
}
// [use the multimedia feature here]
// lock the multimedia feature before exiting the app
try
{
Leadtools.Multimedia.Common.MultimediaSupport.LockModules(Leadtools.Multimedia.Common.LockType.Application,
pszAppId);
}
catch
{
return;
}
_result = true;
}
