我一直在尝试用 LibreOffice 替换 vb6 应用程序中的 Office OLE。
我已经取得了一些成功，但是，我在尝试搜索文本，然后根据找到的文本创建光标，然后在文档中的该光标点插入图像时失败了。
我已经能够拼凑出工作代码，使我能够搜索文本、替换文本和插入图像，但是，我似乎无法弄清楚如何创建一个允许我在以下位置插入图像的光标文字所在的步伐是我发现的。在提供的示例中，文档中的 [PICTUREPLACEHOLDER] 文本。
以前有人这样做过吗？他们对如何创建一个允许我指定图像插入位置的光标有什么建议吗？
我已经包含了 VB6 测试应用程序的代码，以便您可以查看源代码以了解其当前的工作方式。
如有任何建议，我们将不胜感激。
请注意 - 这是实验代码 - 非常粗糙且准备就绪 - 远不是最终代码 - 只是想弄清楚它如何与 LibreOffice Writer 配合使用。
要运行此程序，您需要创建一个带有按钮的空 vb6 应用程序。
您还需要安装 LibreOffice。
非常感谢
杆。

最佳答案
看来您需要将 View 光标移动到找到的位置。
Found = oDoc.findFirst(SearchDescriptor)
oVC = oDoc.getCurrentController().getViewCursor()
oVC.gotoRange(Found, False)
oVC.setString("")
