Application Startup and Shutdown
In the code snippets below, the methods StartStyleVision_Click and ShutdownStyleVision_Click are those assigned to buttons in the AutomateStyleVision example that, respectively, start up and shut down the application. This example is located in the C# subfolder of the API Examples folder (see the file Form1.cs):
Windows 7, Windows 8, Windows 10, Windows 11 | C:\Users\<username>\Documents\ |
You can compile and run the project from within Visual Studio 2012/2013/2015/2017/2019/2022.
Starting StyleVision
The following code snippet from the AutomateStyleVision example shows how to start up the application.
// Handler for the "Start StyleVision" button
private void StartStyleVision_Click(object sender, EventArgs e)
{
if (StyleVision == null)
{
Cursor.Current = Cursors.WaitCursor;
// If there is no StyleVision instance, create one and make it visible.
StyleVision = new StyleVisionLib.Application();
StyleVision.Visible = true;
Cursor.Current = Cursors.Default;
}
else
{
// If an instance of StyleVision is already running, make sure it's visible
if (!StyleVision.Visible)
StyleVision.Visible = true;
}
}
Shutting down StyleVision
The following code snippet from the AutomateStyleVision example shows how to shut down the application.
// Handler for the "Shutdown StyleVision" button
// Shut down the application instance by explicitly releasing the COM object.
private void shutdownStyleVision_Click(object sender, EventArgs e)
{
if (StyleVision != null)
{
// Allow shut-down of StyleVision by releasing UI
StyleVision.Visible = false;
// Explicitly release the COM object
try
{
int i = System.Runtime.InteropServices.Marshal.ReleaseComObject(StyleVision);
while (System.Runtime.InteropServices.Marshal.ReleaseComObject(StyleVision) > 0) ;
}
finally
{
// Disallow subsequent access to this object.
StyleVision = null;
}
}
}
