window.open后不能缩放

不可缩放。windowopen后不能缩放，大小都不能调整，只能滚动，除非将该页面关闭之后再重新打开，将该页面不放大即可。windowopen常用来在新的window或新的tab页打开一个页面或文件(如、PDF等)。

// C# public void OutlookUI() { // Create an instance of each control being used thistreeView1 = new SystemWindowsFormsTreeView(); thislistView1 = new SystemWindowsFormsListView(); thisrichTextBox1 = new SystemWindowsFormsRichTextBox(); thissplitter2 = new SystemWindowsFormsSplitter(); thissplitter1 = new SystemWindowsFormsSplitter(); thispanel1 = new SystemWindowsFormsPanel(); // Insert code here to hook up event methods // Set properties of TreeView control thistreeView1Dock = SystemWindowsFormsDockStyleLeft; thistreeView1Width = thisClientSizeWidth / 3; thistreeView1TabIndex = 0; thistreeView1NodesAdd("treeView"); // Set properties of ListView control thislistView1Dock = SystemWindowsFormsDockStyleTop; thislistView1Height = thisClientSizeHeight 2 / 3; thislistView1TabIndex = 0; thislistView1ItemsAdd("listView"); // Set properties of RichTextBox control thisrichTextBox1Dock = SystemWindowsFormsDockStyleFill; thisrichTextBox1TabIndex = 2; thisrichTextBox1Text = "richTextBox1"; // Set properties of Panel's Splitter control thissplitter2Dock = SystemWindowsFormsDockStyleTop; // Width is irrelevant if splitter is docked to Top thissplitter2Height = 3; // Use a different color

窗口每OnSize一次，获取一次它的大小，与程序启动时的大小做比较，算出其比例，调用自定义函数，在自定义函数中获取每个控件的大小GetDlgItem(IDC_XXX)->GetWindowRect(&rc);

然后把每个控件进行按比例缩放，使用MoveWindow函数

各函数具体用法请查msdn

DPI is how scaling setting is implemented Their relationship is:

96 DPI = 100% scaling

120 DPI = 125% scaling

144 DPI = 150% scaling

192 DPI = 200% scaling

Read the DPI setting like so:

// C# code to get dpi setting:

float dpiX, dpiY;

Graphics graphics = thisCreateGraphics();

dpiX = graphicsDpiX;

dpiY = graphicsDpiY

You'll have to make sure that your program is set to DPI aware in manifest, otherwise it may return 96 in all settings
