使用java访问桥功能，除了“setTextContents”之外，Everything似乎都能正常工作。

本文介绍了使用java访问桥功能，除了“setTextContents”之外，Everything似乎都能正常工作。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我们正在使用Java Access Bridge（Windows访问桥DLL）尝试将文本发送到java窗口的字段。我们初始化了A.P.I.，成功检测到了一个java窗口（这只能在第二次调用isJavaWindow函数时正常工作）。我们可以通过getAccessibleContextFromHWND获取可访问的上下文。然后我们使用上下文来递归孩子，直到我们找到有问题的文本框。我们可以使用getTextInfo函数来读取字段的内容，getAccessibleContextInfo函数返回良好的数据。我可以看到该字段的属性可通过accessibleContextInfo数据结构进行编辑，但setTextContents函数始终返回false。这是C＃中的代码片段用法（我们也尝试过使用Autoit）A.P.I。版本2.0.2 public 部分 类 Form1：表格 { public Form1（） { InitializeComponent（）; } private void button1_Click（ object sender，EventArgs e） { // 枚举窗口 JavaAPIFunc.Windows_run（）; bool found = false ; Int32 VmId = 0 ; AccessibleContext Ac = new AccessibleContext（）; AccessibleContextInfo Info = new AccessibleContextInfo（）; foreach （KeyValuePair< intptr，> lWindow in OpenWindowGetter.GetOpenWindows（）） { IntPtr lHandle = lWindow.Key; string lTitle = lWindow.Value; if （JavaAPIFunc.isJavaWindow（（HWND）lHandle）） { MessageBox.Show（ 找到一个java窗口）; JavaAPIFunc.getAccessibleContextFromHWND（lHandle， out VmId， out Ac）; found = true ; break ; } } 如果（找到） { TraverseTheBullshitInterface（VmId，Ac ）; } } private AccessibleContext TraverseTheBullshitInterface（ Int32 VmId，AccessibleContext AccessContext） { AccessibleContextInfo Info = new AccessibleContextInfo（）;

< / pre > We are using the Java Access Bridge (windows access bridge DLL) in trying to send text to a java window’s fields. We have initialized the A.P.I., successfully detected a java window (this only works correctly on the second call to the "isJavaWindow" function). We are able to obtain the accessible context via "getAccessibleContextFromHWND". We then use the context to recurse through the children until we find the text box in question. We are able to use "getTextInfo" function to read the contents of the field and the "getAccessibleContextInfo" function is returning good data. I can see that the property of the field is editable via the accessibleContextInfo data structure, however the "setTextContents" function always returns false.
