阅读文本测试

Question

有一个在编码的UI测试WinEdit类的错误/限制：重写OnKeyDown方法或订阅在一个文本框中KeyDown事件时，无法使用WinEdit.Text属性。

也就是说，当你有这个...

private void myTextbox_KeyDown(object sender, KeyEventArgs e) 
{ 
    // ... 
} 

...这是行不通的：

var edit = new WinEdit(ancestor); 
edit.SearchProperties[WinControl.PropertyNames.ControlName] = "myTextbox"; 
edit.Text = "New value"; // This doesn't work 

我找到一个变通的设定值here ：

var edit = new WinEdit(ancestor); 
edit.SearchProperties[WinControl.PropertyNames.ControlName] = "myTextbox"; 
Mouse.Click(edit); 
System.Windows.Forms.SendKeys.SendWait("New value"); 

我的问题：没有人知道一个工作一个轮阅读价值？

var edit = new WinEdit(Window); 
edit.SearchProperties[WinControl.PropertyNames.ControlName] = "myTextbox"; 
string actual = edit.Text; // This doesn't work 

Answer 1

我发现了一个变通自己：

[DllImport("user32.dll", EntryPoint = "SendMessage", CharSet = CharSet.Auto)] 
public static extern bool SendMessage(IntPtr hWnd, int msg, int wParam, StringBuilder lParam); 

const int WM_GETTEXT = 0x000D; 

var edit = new WinEdit(Window); 
edit.SearchProperties[WinControl.PropertyNames.ControlName] = "myTextbox"; 
var sb = new StringBuilder(1024); 
SendMessage(edit.WindowHandle, WM_GETTEXT, sb.Capacity, sb); 
string actual = sb.ToString(); 

Answer 2

的解决方案是：

假设你有一个文本框一个窗口形式。

//Launch your Application 
ApplicationUnderTest mainWindow = 
ApplicationUnderTest.Launch(@"D:\Samples\YourApplication.exe"); 

//Search Text box in your windows Form 
var username = new WinWindow(mainWindow); 
username.SearchProperties[WinControl.PropertyNames.ControlName] = "txtUserName"; 

//To Set Text or get, Initialize WinEdit object and asign searched object username to WinEdit object editUsername 
WinEdit editUsername = new WinEdit(username) {Text = "Pakistan"}; 

//get text from textbox username 
string text = editUserName.Text;
