Hi all:

I just got 120 (GetLastError()) from GetCurrentDirectory() on WinME, that means the API doesn't implemented. Is there any other reason this call may fails? and any other substitute?

Are you sure GetLastError returned 120? The documentation says GetCurrentDirectory works on Windows ME too. Here[^] the link is. (See the requirements section there). Use FormatMessage and display your error right there.

Yes, I noticed the requirement section, and that was what make me wonder. I try to append the API with "::" but to no avail so far.

But I did see the two functions exported form Kernel32.dll from WinME:
GetCurrentDirectoryA and W

Note that if your project is unicode aware, then the unicode version of this function,

GetCurrentDirectoryW

will be called. You will need MLU (Microsoft layer for unicode) installed on your Windows ME machine.

PS: If you don't care for unicode, you will have to make an explicit call to

GetCurrentDirectoryA

Exactly, GetCur...A works! Thanks a lot.

I would strongly suggest not to use ANSI version of a call in a unicode project. Install MLU and use the Unicode version. The major harm in getting it done this way is that if the path contains unicode characters, this call will fail again.

You are probably an experienced VB programmer. The reason I say that is that all DLLs created by VB are COM/ActiveX objects. C++ uses Windows in a more direct manner and can often create DLLs that are not COM/ActiveX objects. When communicating with C++ programmers, if you say DLL when you mean to say COM/ActiveX object, then you are more likely to confuse us.

There are many ways to use MFC for databases. You should read the documentation. There is (was?) even a MFC tutorial about database programming using MFC.

No boss. I need to use simple C++. I can't include advanced features like WMI. Do you have any concept how to get it? Please help me. I am badly in need of it.

i dont think it will help him. it will give the volume serial number that is given by the windows when u format the drive. the volume serial number is not a permanent one. it will change every time u format the drive. the volume serial number can be changed programatically .

The Manufacturer's serial number can't be retrieved by GetVolumeInformation(). The manufacturer's serial number and model number is embedded in the Firmware of the disk. it is a permanent one and can't be changed programatically since it is kept in ReadOnly area of the disk. U can use WMI classes or even SMART (Self Monitoring Analysis And Reporting Technology)functions to retrive the serial number. Reading through the IO ports may be another method but its a very unreliable one i suppose. There are plenty of examples that are available on the net but the code is in VB. Use Google and see if u can get some examples in C++. Surely the link given by WhiteSky will help.

Good Luck

vijay.
