FindFirstFile fails on Windows 64 XP

If yes, then do you have the prototypes of functions exposed from that dll? Declare a prototype and use LoadLibrary to load the DLL.

Hello,

When I try to run the following program on any of the OS, except 64-bit windows versions, I don't have any problem, but if I try to run the program on 64-bit system, I don't call fails with error no. 3.

My specific requirement is to get the contents of the following directory
under Windows 64 - XP it is= "C:\windows\system32\config". I face problem only when accessing this directory, I could access all the other directories.

I tried this using Visual Studio 2005.

Following are the code lines

WIN32_FIND_DATAW pTempFind;

mbstowcs(szTemp, "C:\\WINDOWS\\system32\\config\\*", 256);

hFile = FindFirstFileW(szTemp, &pTempFind);

Can someone pls. tell me what could be the reason for this? any solution is highly appreciated.

Regards,

Adi

Do you have appropriate permission for that folder?

Yes.

But the problem is that, this happens only on 64-bit system. I tried this with administrative login also, but then also it fails.

If I write the VB.NET applications, i.e. using the Open Dialog, then it shows me this folder.

So what could be the problem?

Regards,

Adi

If FindFirstFile() is failing and GetLastError() is returning 3, that equates to ERROR_PATH_NOT_FOUND.

Actually it's a long interger and its usage is pretty strightforward, see MSDN for time function. Smile | :)

Actually ... with VS 2005 time_t is either __int64 or long integer depending on whether _USE_32BIT_TIME_T is defined or not.

Hi,

Could anybody tell me about typecasting.How to convert a simple int to a CString.I want to return a integer value through the messagebox.

Thank you

Siddharth

If just displaying an integer value in message box is your problem, use CString::Format for that.

CString str;
int i = 68;
str.Format("%d is an integer and %c is a character", i, i);
AfxMessageBox(str);

Hi,

I entered this code,
Now it is displaying some garbage value???
Actually, iam getting that integer through a edit control like,

int s;
m_height.GetDlgItemInt(s,NULL,TRUE);

m_height is the value entered in the edit box.

Thank you,

AfxMessageBox(str);

m_height should be a CEdit object. Then you can use its GetWindowText() method.
