使用 ShowWindow 显示便签会导致“漏洞"在粘性 [英] Show Sticky Note using ShowWindow cause "holes" in the stickies

问题描述

我正在使用以下内容通过其句柄显示/隐藏窗口:

[DllImport("user32.dll")] private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);//ShowWindowAsync() 的 Win32 API 常量私有常量 int SW_HIDE = 0;私有常量 int SW_SHOW = 5;ShowWindowAsync(_hWnd, SW_SHOW);//橱窗ShowWindowAsync(_hWnd, SW_HIDE);//隐藏窗口

当我隐藏便笺然后再次显示它们时，它会在便笺中造成视觉洞"，我必须关闭便笺并重新打开.

问题截图如下:

我认为该问题特定于粘滞便笺.
我不知道为什么会这样，但我想以某种方式解决它..

我考虑过检查窗口是否是粘滞便笺，如果是，则打开/关闭它而不是显示/隐藏会起到相同的作用，但我真的不喜欢它 - 感觉很笨拙.

解决方案

从 ShowWindowAsync() 更改为 ShowWindow() 解决了问题.

我不知道为什么 ShowWindowAsync() 会导致这个问题，我希望在这里得到一个有教育意义的答案，但现在，只要我的问题得到解决，我就很高兴.

I am using the following to Show/Hide window by its handle:

[DllImport("user32.dll")] private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);

// Win32 API Constants for ShowWindowAsync()
private const int SW_HIDE = 0;
private const int SW_SHOW = 5;

ShowWindowAsync(_hWnd, SW_SHOW); //Show Window
ShowWindowAsync(_hWnd, SW_HIDE); //Hide Window

When I hide Sticky Notes and then Show them again it cause visual "holes" in the stickies and I have to close the Sticky Notes and reopen.

Here's a screenshot of the problem:

I believe the problem is specific to the Sticky Notes.
I dont know why it happens but I would like to solve it somehow..

I thought about checking if the window is Sticky Notes, and if it is then Open/Close it instead of Show/Hide will act the same but I dont really like it - feels hacky.

解决方案

Changing from ShowWindowAsync() to ShowWindow() solved the problem.

I dont know why the ShowWindowAsync() cause this problem and I wish for an educating answer here but for now, as long as my problem is solved I am happy.
