Then do the comparing with user inputs?
I appreciate your help all the time...

yes...
like where strInput = "-09:00"
CString strTest;
int i;
for(i=0;i<=m_pszTimeZones.GetUpperBound();i++)
{
strTest = m_pszTimeZones.GetAt(i);
strTest = strTest.Mid(4,6);
if ( strTest == strInput)
break;
}

Ok, thanks. I'll check it and let you know.

Hey dan o, your code works fine. Where I'm going wrong is the use of my buffer. I'm not sure what exactly happened, but the changing of the buffer size for different time zones gives an error.
Thanks buddy,
At the same time, I'm try to do another thing. Say I want to get both display name and standard zone name. How can I do that through the above your code.
I appreciate your help all the time...

ok, anyway
just closing this item now...
just make a new stringarray
CStringArray m_pszTimeZonesNames
if (iRet == ERROR_SUCCESS)
{
ZeroMemory(&buffer, sizeof(buffer));
dwSize = sizeof(buffer); //again
iRet = RegQueryValueEx(Key, _T("Std"), NULL, &dwType, (BYTE *)buffer, &dwSize);
if (iRet == ERROR_SUCCESS)
{
strValue.Format(_T("%s"), buffer);
m_pszTimeZonesNames.Add( strValue );
}
have a nice day

That's what I have tried. But when I add a CStringArray and compile its ok, but I can't run the code. When I run following exception given,
Unhandled exception at 0x00414ff3 in TimeZone.exe: 0xC0000005: Access violation writing location 0x00000020.
on following line of code.
m_pMainWnd = &dlg;
I have no idea about that. Even on CStringArray documentation there is no such explanation.
I appreciate your help all the time...

i wonder if you did exactly as below
.h
m_pszTimeZones
m_pszTimeZonesNames
.cpp
void <myclassname>::TestTZ()
{
HKEY hKey, Key;
DWORD dwType = REG_SZ;
int iRet = 0;
CString strName, strValue, strPath, strKey;
strPath = _T("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Time Zones");
iRet = RegOpenKeyEx(HKEY_LOCAL_MACHINE, strPath, 0, KEY_READ, &hKey);
if (iRet != ERROR_SUCCESS)
return;
TCHAR achKey[MAX_PATH];
TCHAR achClass[MAX_PATH] = _T("");
DWORD cchClassName = MAX_PATH;
DWORD cSubKeys;
DWORD cbMaxSubKey;
DWORD cchMaxClass;
DWORD cValues;
DWORD cchMaxValue;
DWORD cbMaxValueData;
DWORD cbSecurityDescriptor;
FILETIME ftLastWriteTime;
DWORD i;
DWORD retCode;
TCHAR buffer[MAX_PATH];
DWORD dwSize = sizeof(buffer);
// Get the class name and the value count.
RegQueryInfoKey(hKey, // key handle
achClass, // buffer for class name
&cchClassName, // length of class string
NULL, // reserved
&cSubKeys, // number of subkeys
&cbMaxSubKey, // longest subkey size
&cchMaxClass, // longest class string
&cValues, // number of values for this key
&cchMaxValue, // longest value name
&cbMaxValueData, // longest value data
&cbSecurityDescriptor, // security descriptor
&ftLastWriteTime); // last write time
// Enumerate the child keys, until RegEnumKeyEx fails. Then
// get the name of each child key and copy it into the list box.
for (i = 0, retCode = ERROR_SUCCESS;retCode == ERROR_SUCCESS; i++)
{
ZeroMemory(&achKey, sizeof(achKey));
cbMaxSubKey = sizeof(achKey);
retCode = RegEnumKeyEx(hKey, i, achKey, &cbMaxSubKey, NULL, NULL, NULL, &ftLastWriteTime);
if (retCode == (DWORD)ERROR_SUCCESS)
{
strName.Format( _T("%s"), achKey);
strKey = strPath + "\\" + strName;
iRet = RegOpenKeyEx(HKEY_LOCAL_MACHINE, strKey, 0, KEY_READ, &Key);
if (iRet == ERROR_SUCCESS)
{
ZeroMemory(&buffer, sizeof(buffer));
dwSize = sizeof(buffer); //again
iRet = RegQueryValueEx(Key, _T("Display"), NULL, &dwType, (BYTE *)buffer, &dwSize);
if (iRet == ERROR_SUCCESS)
{
strValue.Format(_T("%s"), buffer);
m_pszTimeZones.Add( strValue );
}
if (iRet == ERROR_SUCCESS)
{
ZeroMemory(&buffer, sizeof(buffer));
dwSize = sizeof(buffer); //again
iRet = RegQueryValueEx(Key, _T("Std"), NULL, &dwType, (BYTE *)buffer, &dwSize);
if (iRet == ERROR_SUCCESS)
{
strValue.Format(_T("%s"), buffer);
m_pszTimeZonesNames.Add( strValue );
}
}
RegCloseKey(Key);
}
}
}
RegCloseKey( hKey );
}</myclassname>

Oops, it's work.
I have to clear the array after certain time I think. Do this after some time of use the array.
m_pszTimeZones.RemoveAll();
Now seems it is work.
Another thing also tested by me.
On comparing of user input with array element, if the user input is not found what happened.
for(i=0;i<=m_pszTimeZones.GetUpperBound();i++)
{
strTest = m_pszTimeZones.GetAt(i);
strTemp = m_pszTimeZones.GetAt(i);
stdTT = m_pszNames.GetAt(i);
strTest = strTest.Mid(4,6);
if ( strTest == strIn)
{
SetDetails(strTemp);
SetDlgItemText(IDC_STD, stdTT);
break;
}
else
{
AfxMessageBox("Error");
break;
}
}
This is what I have tried. Because of the second break it wont iterate. If removed the second break, get the error message until it is found. How should I avoid it.
I appreciate your help all the time...

SetDlgItemText(IDC_STD, stdTT);

}
}
if (!bFound)

Hmm, thanks it works. So, it's better to rate your advice to use of CStringArray.

Hi all,
After completing the time zone application now I'm going to workout a similar application.
Say I have a folder which contain large number of files. I want to read that folder and collect some information on those files. In details view of a folder we can see that lots of details are available.
eg: File Name, Size, Date Created, Date Modified and many more.
I want to read a specific folder and collect those details. So from where I should start this work.
I appreciate your help all the time...

perhaps next code snippet helps you
CStringArray m_pszFileNames
void <myclass>::TestFile()
{
struct _finddata_t g_file;
long hFile, lTime;
CString strName, strPath, strCurrentPath;
m_pszFileNames.RemoveAll();
strPath = "c:\testpath";
/* Get the current working directory: */
char buffer[_MAX_PATH];
_getcwd( buffer, _MAX_PATH );
strCurrentPath.Format( _T("%s"), buffer);
_tchdir(strPath);
if( (hFile = _findfirst( "*.*", &g_file )) == -1L )
{
printf( "No files in current directory!\n" );
}
else
{
strName = g_file.name;
m_pszFileNames.Add(strName);
/* Find the rest of the *.* files */
while( _findnext( hFile, &g_file ) == 0 )
{
strName = g_file.name;
m_pszFileNames.Add(strName);
lTime = g_file.time_write;
}
_findclose( hFile );
}
_tchdir(strCurrentPath);
}

Hi Experts,
I want to name of some API to perfome the following tasks:
1.How to Restart the system programatically?
2.API that determines system getting shutdown.
3.API that tells system is starting.
Thanx in advance.

If the system is in starting state then how can your application be running? Or you want your application to run on startup?

Hi all,

I want to verify this path that this path exist or not and is there a file with same name already created....Is there any api which could help me in doing this........
Thanks

Use CFileFind class & its member functions
this may help you.

PathFileExist is the api you have to use for said problem, also you have to include shlwapi.lib in your program!

You can use of FindFirstFile for check does file exist or no.

I have craeted a CWinThread object for thread. This thread implements a reccurssive type function. I have used SendMessage/PostMessage functions but it is crashing. Please help me by informing exact reason and alternate solution.

|

you will have to be more specific, unless you are expecting some psychic CP member to figure out the 'exact' solution for you...
meanwhile heres a good source on threads that may help you out figure out the problem on your own:

What message are you sending?
Could you show me the code fragment?
|
|
|
|

I have used the following code in the procedure that run under a thread
ULONG64 ulPercent = INT64(m_ulFileCopied * 100)/INT64(ulFileSize);<br />
SendMessage(UM_PROGRESSS_INFO,(WPARAM)ulPercent,0);
In the above code while executing the SendMessage function the system is crashing. I have also used PostMessage function instead of SendMessage but the result is same.
