VB开发人员都会遇到文件定位的问题。VB提供的Dir[(pathname[, attributes])]函数应该可以满足各种文件定位问题。使用Dir函数时，我们必须给它提供文件的全部路径，否则是找不到的。而有时我们往往是不知道文件的路径的，如果要利用该函数来定位文件，我们必须编写一定的代码。笔者在利用该函数编制查找文件的函数时，颇费了些工夫，可是发现查找的效率不高，效果不太理想。那么有没有编码少且更快的方法查找文件呢？笔者后来利用一个 API函数成功地编制了一个高效率的查找文件的函数。-VB developers will face the problem of document location. VB provided by Dir [(pathname [, attributes])] function should be able to satisfy the positioning of various documents. Dir function to use, we must give it the full path to provide a document, otherwise it is not found. And sometimes we often do not know the path to the file, and if want to use this function to locate a document, our code must be prepared. I use the function in the preparation of the document search function, something a lot of work, but found that search efficiency is not high, less than ideal results. Well, there is no code and a faster way less search documents? I was using an API function successfully developed a highly efficient file search function.
