Replacement.Application 是将应用程序对象的引用。当你调用给AddPicture（）上的照片立即在即使执行查找操作之前，在当前位置插入。

我看到两种可能性：

1. 加载的图片，将其放置到Windows剪贴板中，然后执行查找操作指定^ C作为替换文本。 Word将替换^ C与剪贴板的当前内容。这就是文档说：

ReplaceWith

类型：System.Object

可选的对象。

替换文本。若要删除由Find参数指定的文本，使用空字符串（）。您可以指定特殊字符和高级搜索条件，就像您查找的说法去做。要指定一个图形对象或其他非文本项作为替代，移动项目到剪贴板，并指定^ c按钮ReplaceWith。

请不要使用wdReplaceAll，但wdReplaceNone，使查找操作本身并不做任何更换。但是，你就必须在发现地方插入你的内容的机会。这样做，在一个循环，直到不再出现被发现。

This code is replacing the text with an image but its placing the multiple copies of an image and placing them in the beginning of the document. I want the image to be placed at the same position where text was present. My find text is available in the table cell. Is it due to that?

解决方案

Replacement.Application is a reference to the application object. When you call AddPicture() on that, the picture is immediately inserted at the current position before the find operation is even executed.

I see two possibilities:

1. Load the picture, place it into the Windows clipboard and then execute the find operation specifying "^c" as replacement text. Word will replace "^c" with the current content of the clipboard. This is what the documentation says:

ReplaceWith
Type: System.Object
Optional Object.
The replacement text. To delete the text specified by the Find argument, use an empty string (""). You specify special characters and advanced search criteria just as you do for the Find argument. To specify a graphic object or other non-text item as the replacement, move the item to the Clipboard and specify "^c" for ReplaceWith.

2. Do not use wdReplaceAll, but wdReplaceNone, so that the find operation itself does not do any replacing. But you then have the chance to insert your content at the place found. Do that in a loop until no more occurrence is found.
