1. Permission issues
Please make sure that the folder "Guest User" of the file you upload has permission to write, some are stored in the database, and also have permission to modify.
2. File size limit
IIS 6 For security reasons, the default maximum request is 200K (that is, the maximum submission data limit is 200KByte, 204800Byte).
Solution:Close the IIS Admin Service
Open \Windows\system32\inesrv\
Modify the value of ASPMaxRequestEntityAllowed to what you need, the default is 204800
Start IIS Admin Service
After modification, the file needs to be modified at the same time
In , the default size of the uploaded file is 4096 KB, which is 4M, but you can change this data in it. The most commonly used method is to directly modify the file in C:\WINDOWS\\Framework\v1.1.4322\CONFIG directory (the Framework version will be different, you will enter the directory of the version you use), and find httpruntime on this line to change the value of maxRequestLength to the ideal value. For example, if you want 8M, enter 8192.
3. Chinese system, installed English patch for IIS
After inspection, it was found that the host used by the customer was the Chinese version of Windows 2003, and later changed to the English version of Windows, and an error occurred.
Generally, the same problem sometimes occurs after the system has been upgraded to IIS or patched. We just need to add a piece of code before the ASP file.
<!-- must be fist line in ASP -->
<% @LCID=4100 %>
4. Language issues
Set the regional settings to [China] in the control panel
5, date, time issue
In the control panel, set the time format to: H:mm:ss in the control panel, and change the time zone to Beijing in the control panel "Date Time". (The reason for changing this is because some attachments are uploaded with time named. If the time format is incorrect, it will cause the program to report an error)
6. The Chinese name or path used by the uploaded file
If you use ASP to upload without components, because Chinese is not supported, you need to check whether Chinese is included on the upload path.
7. Report "Microsoft VBScript runtime error Error '800a0005' Invalid procedure call or parameter: 'chr' " error (My problem is this)
Microsoft VBScript runtime error '800a0005' Invalid procedure call or argument: 'Chr' /admin/inc/,
line 75 This error may be because the server is in English because the Chr function returns a String containing characters related to the specified character code.
Related syntax: Chr(charcode) The necessary charcode parameter is a Long used to identify a certain character. Description: Numbers between 0 and 31 are the same as standard non-printed ASCII codes.
For example, Chr(10) can return newline characters. The normal range for charcode is 0 – 255. However, in DBCS systems, the actual range of charcode is -32768 to 65535. Note: The ChrB function acts on byte data contained in the String. ChrB always returns a single byte, instead of returning a character, a character may be one or two bytes. The ChrW function returns a String containing Unicode. If it is not supported by Unicode, its function is the same as the Chr function.
So just replace the chr in line75 code that makes the error: stemp=stemp&chr(AscW(ChrB(AscB(upfile_5xSoft_Stream.Read(1)))&ChrB(c)))) with chrw
