I'm not sure if this is what you're looking for, but you can find a windows app called rasphone.exe in C:\Windows\System32.

So, something like this might help:

ShellExecute(0, 0, _T("rasphone.exe"), 0, 0, SW_SHOW);

When you execute that, it will let you connect, disconnect, and edit properties of you network connections.

Hope it helps. Smile | :)

Have you tried SHGetFolderLocation(NULL, CSIDL_CONNECTIONS, ...)? That would get you a PIDL that can then be used to obtain the actual path of the "Network Connections" virtual folder.

The control panel "dialog"?

If so...

// On Vista:
::CreateProcess(_T("C:\\Windows\\System32\\control.exe"),
_T(" /name Microsoft.NetworkAndSharingCenter"),
...

// On older OSs (I didn't test this):
::CreateProcess(_T("C:\\Windows\\System32\\control.exe"),
_T(" ncpa.cpl"),
...

And if that's the wrong dialog, never mind Smile | :)

You may use the Win32 API CreateDirectory to create a new folder.
If the function succeeds, the return value will be nonzero.

Hi,

You can use WIN32 API in MFC also..

Here is sample code for what Rane says:

if (::<code>CreateDirectory</code>("C:\\temp\\", NULL) == 0) // Check if succesfull
{
  // To do when unsuccesfull. Maybe the directory already exists?
}
else
{
  // To do when succesfull
}

RegEnumValue : Not able to retreive registry value for Date format..

Hi,
Can anybody tell me why am I not getting Value's data in below code, in buffer 'pszRegValData' ? The surprising thing is that I am able to receive other value's data in it which has REG_SZ datatype... but the value for which it's not giving any output has REG_SZ as a datatype too.. data for it is "04/26/2007 10:20:01".. It's not giving me data in buffer(pszRegValData) for REG_BINARY too...

retCode = RegEnumValue(hkScanKey, i,
szRegValueName,
&dwRegValNameLen,
NULL,
&dwRegValType,
(LPBYTE)pszRegValData,
&dwRegValLen);

Thanks in advance.

Which is not an error, but means that more data is available.

thanks for the reply. But I am already making sure that buffer size is enough to store the data...by API 'RegQueryInfoKey()' I am getting max length of value's data.. I am executing it before 'RegEnumValue()' and allocating the buffer for value (length returned by 'RegQueryInfoKey' + 1)... still why 234 error ? Frown | :(

I just traced my code and found that for every character it's taking 2 bytes.. and I am allocatiing buffer as per length returned by 'RegQueryInfoKey' which returned length of longest value data... for example actual date string/data(REG_SZ) length is 20 but when 'RegEnumValue' gets the date string/data, the length returned is 40(in last param of 'RegEnumValue').... So I doubled my buffer's size but still it gives me same problem... any suggestions ? I am running my 'console' appln on 32 bit intel proc with 32-bit XP OS on it...

I resolved the prob, after each call we need to set the data buffer size back to max value length... sadly this is not quoted in MSDN! it's hard to understand whats going on wrong in code when MSDN says everytime 'RegEnumValue' iterates thru reg values,it returns the data length... I wasted my night for this silly problem...

With moving the file or figuring out what your temporary folder is?

Use the GetTempPath() function to retrieve the path of the temporary files directory - see the documentation here.

Then to copy the file use the CopyFile() or CopyFileEx() function to copy the file to the temporary directory.

Converting a Text into an Integer

Rane29-Aug-08 20:45

Rane

29-Aug-08 20:45

Hi,

I'm in need of a conversion routine to convert a string into a integer(long). I'm relying on CRT function _tcstol to do this. Below shown is my approach:

main()
{
_TCHAR *q = 0;
char txt[] = "5x";
long l = _tcstol(txt, &q, 10);
if (q && _tcsclen(q))
{
cout<<"Invalid Integer";
}
}

I'm relying on parameter2 in _tcstol to validate a integer. (i.e)the endptr Pointer to character that stops scan.

Will this approach work fine in all cases?

Thanks in Advance
