C#生成dll,其中引用了office的com控件实现文档转换。
当其他winform程序调用时正常。
但注册该dll后,由PHP调用时出错。
try catch了一下,输出“Word 出现问题”。
测试机器上装的是office2007。C#实现文档转换部分:
<span>string</span> fileFolder =<span> Path.GetDirectoryName(wordFilePath); </span><span>string</span> fileNameWithoutExtension =<span> Path.GetFileNameWithoutExtension(wordFilePath); </span><span>string</span> htmlFilePath = fileFolder + <span>@"</span><span>\</span><span>"</span> + fileNameWithoutExtension + <span>@"</span><span>.html</span><span>"</span><span>; Object objWordPath </span>=<span> wordFilePath; Object objHtmlPath </span>=<span> htmlFilePath; MSWord.Application wordApp; MSWord.Document wordDoc; Object Nothing </span>=<span> Missing.Value; wordApp </span>= <span>new</span><span> MSWord.ApplicationClass(); wordDoc </span>= wordApp.Documents.Add(<span>ref</span> objWordPath, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing);<span>//</span><span>===========PHP调用时这下面的语句执行不到</span> <span>object</span> format =<span> MSWord.WdSaveFormat.wdFormatFilteredHTML; wordDoc.SaveAs(</span><span>ref</span> objHtmlPath, <span>ref</span> format, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span><span> Nothing, </span><span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span><span> Nothing); wordDoc.Close(</span><span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span><span> Nothing); wordApp.Quit(</span><span>ref</span> Nothing, <span>ref</span> Nothing, <span>ref</span> Nothing);
dll注册后,PHP调用部分:
<span>php </span><span>$c</span>= <span>new</span> COM("ComLibrary.Test"<span>); </span><span>echo</span> <span>$c</span>->SaveWordAsHtml("D:\\ningtao\\xampp\\htdocs\\test.doc"<span>); </span>?>
不知道是由什么引起的。
初步怀疑有2中可能:
1、dll注册为COM+再被PHP调用时,没有正确的调用office的com组件。
2、被PHP调用时,由于文件的读写权限引起的问题。
大家有没有遇到过类似问题的,该如何解决?
