golang hide window

May 27, 2023 pm 12:37 PM

In program development, hiding windows is a relatively common operation. In some cases, we need to let the program run silently in the background without disturbing the user. Golang is an emerging programming language with good concurrency and performance. So how to implement hidden windows in golang? This article will give you a detailed introduction.

First of all, we need to clarify what a window is. In computer operating systems, a window refers to an area occupied by a program on the interface. In the Windows operating system, there are many types of windows, such as ordinary windows, modal dialog boxes, etc. Normally, we need to use system-level API to hide the window.

In golang, we can hide the window by calling cgo to call the relevant Windows system-level API. The specific steps are as follows:

Step1 Define the Windows API function

In the process of hiding the window, we need to call the ShowWindow function in the Windows API. The ShowWindow function is a simple window display control function that can set the window to hidden, minimized, maximized and other states.

Therefore, in golang, we need to define this function. The specific code is as follows:

type HANDLE uintptr
type HWND HANDLE

const SW_HIDE = 0

func ShowWindow(hwnd HWND, nCmdShow int32) bool {
    _ = showWindow.Call(uintptr(hwnd), uintptr(nCmdShow))
    return true
}

var (
    user32      = syscall.MustLoadDLL("user32.dll")
    showWindow  = user32.MustFindProc("ShowWindow")
)

In the above code, we first define the two types HANDLE and HWND. HANDLE is a reference to the object, and HWND is the handle type of the window. Then, we defined the ShowWindow function, which returns a bool type value indicating whether the operation was successful. The specific implementation process is achieved by calling the showWindow.Call function. Finally, we use the syscall.MustLoadDLL function to load the user32.dll library and the MustFindProc function to find the ShowWindow function.

Step2 Hidden window

After defining the relevant functions, the next step is to implement the operation of hiding the window. The specific code is as follows:

func HideWindow() bool {
    hWnd := GetConsoleWindow()
    if hWnd == 0 {
        return false
    }
    ShowWindow(hWnd, SW_HIDE)
    return true
}

func GetConsoleWindow() uintptr {
    h := syscall.MustLoadDLL("kernel32.dll")
    p := h.MustFindProc("GetConsoleWindow")
    ret, _, _ := p.Call()
    return ret
}

In the above code, we call the GetConsoleWindow function in the HideWindow function to obtain the handle of the console window. If the acquisition fails, false is returned. If the acquisition is successful, the ShowWindow function is called to hide the window. Finally, the operation result is returned.

In the code implementation of this article, we used the two Windows system-level API libraries kernel32.dll and user32.dll. At the same time, we also checked the return result of obtaining the window handle to ensure the correctness and robustness of the program.

Summary

This article introduces the method of using golang to implement window hiding, which is achieved by calling Windows API library functions. Specific steps include defining Windows API functions and implementing the operation of hiding windows. Golang's concurrency performance is excellent. In some scenarios that require window hiding functions, using golang is a very suitable choice.

You should care about the "strings" package in Go because it provides tools for handling text data, splicing from basic strings to advanced regular expression matching. 1) The "strings" package provides efficient string operations, such as Join functions used to splice strings to avoid performance problems. 2) It contains advanced functions, such as the ContainsAny function, to check whether a string contains a specific character set. 3) The Replace function is used to replace substrings in a string, and attention should be paid to the replacement order and case sensitivity. 4) The Split function can split strings according to the separator and is often used for regular expression processing. 5) Performance needs to be considered when using, such as

Mastering the bytes package in Go can help improve the efficiency and elegance of your code. 1) The bytes package is crucial for parsing binary data, processing network protocols, and memory management. 2) Use bytes.Buffer to gradually build byte slices. 3) The bytes package provides the functions of searching, replacing and segmenting byte slices. 4) The bytes.Reader type is suitable for reading data from byte slices, especially in I/O operations. 5) The bytes package works in collaboration with Go's garbage collector, improving the efficiency of big data processing.

You can use the "strings" package in Go to manipulate strings. 1) Use strings.TrimSpace to remove whitespace characters at both ends of the string. 2) Use strings.Split to split the string into slices according to the specified delimiter. 3) Merge string slices into one string through strings.Join. 4) Use strings.Contains to check whether the string contains a specific substring. 5) Use strings.ReplaceAll to perform global replacement. Pay attention to performance and potential pitfalls when using it.
