Use CFileDialog::m_ofn-->lpstrInitialDir .Modify your code like this,

CFileDialog dlg(TRUE, _T("dgl"), _T("Playlist"), OFN_FILEMUSTEXIST, "*.*", this);
dlg.m_ofn.lpstrInitialDir = "c:\\";//mention folder you want to display initialy
dlg.DoModal();

If your window is the current foreground window, clicking its taskbar button automatically minimizes it. You don't have to do anything to get this feature.

create internet shortcut

Hi,
Mine is a unicode Supported application.I have used the following function to create internet shortcut.
CreateShortcutToURL(LPCSTR pszURL, LPCSTR pszLinkFile)
{

HRESULT hRes;
IUniformResourceLocator *pURL = NULL;

// Create an IUniformResourceLocator object
hRes = CoCreateInstance (CLSID_InternetShortcut, NULL,
CLSCTX_INPROC_SERVER, IID_IUniformResourceLocator, (LPVOID*) &pURL);
if (SUCCEEDED(hRes))
{
IPersistFile *pPF = NULL;

hRes = pURL->SetURL(pszURL, 0);

if (SUCCEEDED(hRes))
{
// buffer for Unicode string
int nLen = MultiByteToWideChar(CP_ACP, 0,pszLinkFile, -1, NULL, NULL);
LPWSTR lpszW = new WCHAR[nLen];

// Ensure that the string consists of ANSI characters.
int k= MultiByteToWideChar (CP_THREAD_ACP, 0, pszLinkFile, -1, lpszW, MAX_PATH);
//USES_CONVERSION;

// LPCOLESTR p = T2COLE (pszLinkFile);

hRes = pURL->QueryInterface (IID_IPersistFile, (void **)&pPF);
if (SUCCEEDED(hRes))
{
// Save the shortcut via the IPersistFile::Save member function.
hRes = pPF->Save (lpszW, FALSE);

// Release the pointer to IPersistFile.
pPF->Release ();
}
}
// Release the pointer to IUniformResourceLocator
pURL->Release ();
}
return hRes;
}
But the shortcut is not created when for ex: pszLinkFile= "D:\MyFavorites\Online Bookmarks\button\How to convert char* to WCHAR* in C - C.url" and also sometimes if the atring contains ":" and ">>" such type of characters.At present the string contains "*" .How can i resolve this.

How can we add and delete registry entries in Vista.I wrote the program it is working in XP but it is not working in Vista.
Sample code:LONG Res = RegCreateKeyEx (HKEY_CLASSES_ROOT, lpszKeyName,
0,NULL,
REG_OPTION_NON_VOLATILE ,KEY_ALL_ACCESS,NULL, &hkResult,
NULL);
LONG Res=RegDeleteKey(HKEY_CLASSES_ROOT,lpszKeyName);

In Windows Vista you need to have the application run under Admin privileges. You can do this by creating a manifest file. you can write to HKEY_CURRENT_USER key without having the admin privileges.

Somethings seem HARD to do, until we know how to do them.
