Like this:
BOOL IsAdministrator(void)
{
BOOL fRet = TRUE;
HANDLE hProcess = INVALID_HANDLE_VALUE;
HANDLE hAccessToken = INVALID_HANDLE_VALUE;
UCHAR InfoBuffer[1024] = {0};
PTOKEN_GROUPS ptgGroups = (PTOKEN_GROUPS)InfoBuffer;
DWORD dwInfoBufferSize = 0;
PSID psidAdministrators = NULL;
SID_IDENTIFIER_AUTHORITY siaNtAuthority = SECURITY_NT_AUTHORITY;
UINT x = 0;
hProcess = GetCurrentProcess();
if(!OpenProcessToken(hProcess,TOKEN_READ,&hAccessToken))
return(FALSE);
if(!GetTokenInformation( hAccessToken,TokenGroups, InfoBuffer, 1024, &dwInfoBufferSize))
return(FALSE);
fRet = AllocateAndInitializeSid(
&siaNtAuthority, 2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0, &psidAdministrators);
if (!fRet)
return(FALSE);
for(x = 0; x < ptgGroups->GroupCount; x++)
{
if(EqualSid(psidAdministrators, ptgGroups->Groups[x].Sid))
{
FreeSid(psidAdministrators);
return(TRUE);
}
}
FreeSid(psidAdministrators);
return(FALSE);
}
Which will return true if the current user is a member of BUILTIN\Adminstrators group or false otherwise

IsUserAnAdmin[^] will test whether the user is a member of the Administrators group. This is one of the Settlement Program Interfaces[^], so you may need to use LoadLibrary and GetProcAddress to use it.
However, this only works well in the default environment. An administrator may have assigned rights to other user accounts or groups to give them raised privileges. A better way is simply to try whatever operation needs to be performed, and handle any access-denied errors that occur.

Maybe it was only ever exported by ordinal.
The Settlement Program is something that came out of the anti-trust suit: this is one of the 'revealed' APIs. If you get hold of a recent Platform SDK (December 2002 or later, currently at February 2003), you'll find this function in ShlObj.h. I assume that the appropriate import library (shell32.lib?) contains the necessary import to call the function.
I stand by my earlier statement that this is the wrong way to do it anyway.

Use CRichEditCtrl::StreamOut() and write your own stream callback function, in that you copy raw bits from rich edit control to HGLOBAL.
See the EDITSTREAM and CRichEditCtrl documentation for details.

the callback function is called, passing the data in segments, so should i allocate memory on the heap for each call and the integrate the whole data in a newly allocated memory or is there a way to keep appending data to the buffer allocated only once....(or is there a way to find in advance how much buffer we should have?)
thanks
ahmed

The callback function takes the cb parameter, which contains required size of CRichEditCtrl data. You can grow the HGLOBAL memory with GlobalRealloc.

hello every body
I want to know how can i end an sdi application like what we do in the Dialog application by calling CDialog::OnOk()
Best Regards

I believe the best practice is to post a WM_CLOSE message to your CFrameWnd-derived object. Something like that: AfxGetMainWnd()->SendMessage(WM_CLOSE);

thank u for it is working now

Hi!
I want in my program to be able to input text into an edit control and instead of having to move the mouse and click on the button to get the text input, I want it so that when you press enter, rather than closing the dialog, it will work the same as clicking on the button.
Can someone please help?
Thankyou
Ashman

I have done this some time ago. I don't know exactly how I have done it anymore, but I think I have used CWnd::PreTranslateMessage. If you overload it in your dialog class you can capture the key event before it is sent to the window!

Hi
I think to deactivate Enter Key u have to cancel OnOk() in the virtual member function like the following:
//////////////////////////////////////////////
void CanyDlg::OnOK()
{
// TODO: Add extra validation here
//CDialog::OnOK();
}
//////////////////////////////////////////////
Best Regards

Capture the WM_COMMAND message for your default button (lets say here your default button has the ID IDOK) by overriding the relavant function, CYourDialog::OnOk in this case, then rather than calling the base CDialog::OnOk, move the focus to your edit control, either like this:
GetDlgItem(IDC_MY_EDIT_CTRL)->SetFocus();
Or like this:
SendMessage(WM_NEXTDLGCTL, (WPARAM)GetDlgItem(IDC_MY_EDIT_CTRL)->GetSafeHWnd(), TRUE);
The difference between them is the second is usually more suited to moving the keyboard focus around a dialog box as it updats the button borders correctly, so in full:
void CMyDialog:::OnOk()
{
if(CWnd::GetFocus() == GetDlgItem(IDC_MY_EDIT_CTRL))
{
// edit control focused, so do normal stuff
CDialog::OnOk();
}
else
{
// move focus to edit control
SendMessage(WM_NEXTDLGCTL, (WPARAM)GetDlgItem(IDC_MY_EDIT_CTRL)->GetSafeHWnd(), TRUE);
}
}
This will make enter move the focus to the edit control if something other than the edit control is foucsed, or make enter behave as normal if it is the edit control that's focused

That's all U need in MFC. I know very similar solution in win32sdk. If U need tell?
Cheers!

hi Ashman,
all you have to do is to set the focus on the specific control... you can use
(CEdit*)GetDlgItem(YOUR_Edit_ID))->SetFocus(); to avoid you to move explicitly your mouse upon the EditBox, and in the OnInitDialog(), you tell which button to be pressed when the user presses Enter key by giving it the property Default

I want to initialize a executable, making OS to search for the file.
STARTUPINFO si = {sizeof(si)};<br />
PROCESS_INFORMATION pi;<br />
TCHAR szCommandLine[1024] = {0},*pszCommandLine = 0;<br />
<br />
DWORD lFileName = <br />
SearchPath(NULL,(LPCWSTR)"YPager",(LPCWSTR)".exe",(DWORD)sizeof(szCommandLine), szCommandLine, *pszCommandLine);<br />
<br />
BOOL bCreate = CreateProcessNULL,szCommandLine,NULL,NULL,FALSE,0,NULL,NULL,&si,&pi);
there is no complier error but szCommandLine cannot fill the path.
Any other suggestions to achieve the same goal is appreciated.
Cheers!
Siddharth

Hi,
I use VC6 (SP5) in Windows XP Pro (SP1). I wanted to add Greek/Chinese strings. I edited the .rc files in a Unicode editor, saved the file as UTF-8. But, now, VC6 has problems handling the file. But, if I save it as a normal file, the strings are garbled.
How do I add other language strings to my resource file and what shd I use to compile it?
TIA
MRK

I've noticed that VC6 has problems in dealing with language strings, especially unicode characters. What we do normally is create the structure of the resource file using the VC resource editor, then have the translators to use their text editor (I think they use TextPad), re-include the modified resource file in Visual Studio. DO NOT modifiy in any way the file after it has been translated - do not change dialogs, not accelerators, nothing. If you do get a saved copy of the translated version and copy and paste the text using a text editor to replace the garbled text.
VC7 seems to have addressed the problem.
Hope that helps.
