Sample applications that demonstrate some of those Plugin technologies follow.
On windows the code samples included in the STK install are read only. If you wish to work with one of the samples, you should copy the appropriate directory to an area on the local machine where you have write permissions, and then mark the files writable before trying to compile them.
Registering Windows Script and Binary COM Component Plugins on Vista with UAC Enabled
If User Account Control (UAC) is enabled on Vista, and you attempt to register a Windows Script or binary COM Component plugin, you will receive the following error:
The module C:\Windows\<system32>\scrobj.dll was loaded but the call to DllRegisterServer failed with error code 0x80070005.
Use the following workaround to register the plugin:
- Run the command in elevated mode. Right click on "Command Prompt" and select "Run as Administrator".
- Navigate to the directory containing the plugin(s) that you want to register.
- Run the following command: c:\windows\system32\regsvr32 /i:<plugin name> c:\windows\system32\scrobj.dll
Using Code Samples
The code samples included in the STK install are read only. To work with any of the installed code samples:
- From the Windows Start menu, select STK 12->STK Codesamples 12 to access <STK install folder>/CodeSamples/CodeSamples.zip.
- Copy CodeSamples.zip to a folder where you have write permissions and unzip the file.
- Change the properties of the files to writable before compiling them.
