inlineprivate

Handles the SelectedIndexChanged event of comboBox2. Sets the quality based on the selected index in the comboBox.

Parameters

sender	The source of the event.
e	The EventArgs that contains the event data.

This method retrieves the selected index from comboBox2 and sets the quality based on the selected index. It first checks if a valid index is selected, then it parses the quality value from the qualitys array and removes the '' symbol. The SetQuality method is then called with the parsed quality value to set the quality.

CreateImageNode()

async Task< Node > xeno_rat_server.Forms.WebCam.CreateImageNode ( )

inlineprivate

Creates an image node and returns it. If the image node already exists, returns the existing node.

Returns

The created or existing image node.

This method creates an image node if it does not already exist. If the image node already exists, it returns the existing node. The method sends a byte array with a value of 4 to the client asynchronously. It then creates a subnode asynchronously using the parent client and assigns it to the variable SubSubNode. The method sets the type and ID of the subnode using Utils.SetType2setIdAsync method and checks if the ID is not equal to -1. If the ID is not equal to -1, it returns the type and ID asynchronously using Utils.Type2returnAsync method and sends a byte array to the client. The method receives a byte array from the client and checks if it is null or the first element is 0. If so, it disconnects the subnode and returns null. If the ID is equal to -1, it disconnects the subnode and returns null. Finally, it returns the created or existing image node.

Dispose()

override void xeno_rat_server.Forms.WebCam.Dispose ( bool disposing )

inlineprotected

Releases the unmanaged resources used by the component and optionally releases the managed resources.

Parameters

disposing

True to release both managed and unmanaged resources; false to release only unmanaged resources.

This method releases the unmanaged resources used by the component and optionally releases the managed resources. If disposing is true, this method disposes of all managed resources. If disposing is false, this method releases only the unmanaged resources.

GetCamera()

async Task< string[]> xeno_rat_server.Forms.WebCam.GetCamera ( )

inline

Asynchronously retrieves the list of cameras from the client and returns the result.

Returns

An array of strings containing the list of cameras retrieved from the client.

This method sends a request to the client to retrieve the list of cameras and awaits the response. The response is then parsed to obtain the number of cameras, and individual camera names are received and stored in an array. The array of camera names is then assigned to the 'Cameras' property of the class and returned as the result.

InitializeAsync()

async Task xeno_rat_server.Forms.WebCam.InitializeAsync ( )

inlineprivate

Initializes the object asynchronously by creating an image node, adding temporary on disconnect, refreshing cameras, and starting the receive thread.

This method initializes the object asynchronously by performing the following tasks:

1. Creates an image node by awaiting the result of the CreateImageNode method.
2. Adds temporary on disconnect by invoking the AddTempOnDisconnect method on the created ImageNode.
3. Refreshes cameras by awaiting the result of the RefreshCams method.
4. Starts the receive thread by invoking the RecvThread method.

RecvThread()

async Task xeno_rat_server.Forms.WebCam.RecvThread ( )

inline

Asynchronously receives image data and updates the picture box with the received image.

This method continuously receives image data from the connected ImageNode and updates the picture box with the received image. If the received data is null, the method breaks the loop and stops receiving. If the application is in a playing state, the received image data is converted to an Image object and displayed in the picture box. The method uses asynchronous operations for receiving data to avoid blocking the main thread.

Exceptions

Exception

Thrown if there is an error in receiving or processing the image data.

RefreshCams()

async Task xeno_rat_server.Forms.WebCam.RefreshCams ( )

inline

Refreshes the list of cameras and updates the UI accordingly.

This method asynchronously retrieves the list of available cameras using the GetCamera method. It then updates the UI by clearing the existing items in the comboBox1 and adding the new camera names. If no cameras are available, it disables the button2; otherwise, it enables the button and sets the camera to the first available one using the SetCamera method.

Exceptions

Exception

An exception may be thrown if there is an error while retrieving the list of cameras or setting the camera.

Returns

A task representing the asynchronous operation.
