In the open save file dialog box, you can use the MSComDlg. CommonDialog object and set the type filter. However, you must set the MaxFileSize attribute. Otherwise, an error occurs. The specific implementation code is as follows.
It can be used in ie5678 after testing. in the XP system. new ActiveXObject ("MSComDlg. commonDialog ") object cannot be created. I found a lot of information and it seems that it still cannot be solved. we recommend that you use the file control.
If any expert has more convenient solutions, I hope you can give me some advice !!!
