C# development example-customized screenshot tool (9) using custom cursor and cursor when taking QQ screenshots (picture)

When using the screenshot function of QQ, do you think its cursor is cool? Today I will talk about how to apply a custom cursor and use the QQ screenshot cursor in our screenshot tool.

Open resource:

Switch to file resourceView:

Open the resource file directory and copy the cursor file to this directory:

Required cursorFile download：C#Software development example. Customize the cursor file used in your own screenshot tool

Select theResources directory and refresh, Display the cursor file just copied in:

Select the cursor file and drag it to the file view of the resource:

Resources The first letter of the word in the resource name is changed to uppercase.

Cursor preview:

Add privatevariableinForm1 class:

#region 自定义光标 System.Windows.Forms.Cursor cursorCross = null; System.Windows.Forms.Cursor cursorDefault = null; System.Windows.Forms.Cursor cursorText = null; System.Windows.Forms.Cursor cursorColor = null; #endregion

Add WindowsAPIStatement:

[DllImport("user32.dll")] private static extern IntPtr LoadCursorFromFile(string fileName);

Add a method to obtain the cursor from existing resources:

/// 
 /// 从已有资源中获得光标 /// 
 ///  ///  public static Cursor getCursorFromResource(byte[] resource) { byte[] b = resource; FileStream fileStream = new FileStream("cursorData.dat", FileMode.Create); fileStream.Write(b, 0, b.Length); fileStream.Close(); Cursor cur = new Cursor(LoadCursorFromFile("cursorData.dat")); return cur; }

Add window initializationEvent handlingProgram, add a custom cursor:

/// 
 /// 窗口初始化事件处理程序 /// 
 private void Form1_Init() { this.isCuting = false; this.beginPoint = new Point(0, 0); this.endPoint = new Point(0, 0); cursorDefault = getCursorFromResource(Properties.Resources.Cursor_Default); cursorCross = getCursorFromResource(Properties.Resources.Cursor_Cross); cursorText = getCursorFromResource(Properties.Resources.Cursor_Text); cursorColor = getCursorFromResource(Properties.Resources.Cursor_Color); }

Set the default cursor, handle the cursorstatus:

Add in theelsecondition of the ShowForm method :

this.Cursor = cursorDefault;

Add code in the ExitCutImage method:

this.Cursor = cursorDefault;

Add the mouse to enter the Form1 form event handler:

/// 
 /// 鼠标进入Form1窗体事件处理程序 /// 
 ///  ///  private void Form1_MouseEnter(object sender, EventArgs e) { this.Cursor = cursorDefault; }

Form1'sconstructorAdd code:

Form1_Init();

Ok, compile, take a screenshot to see the effect!

Multiple cursor files have been added here, but only one is used.Otherswill be used in functions added in the future.
