how do i enable visual styles in C++ ?
i'v done creating all my window and now i want my controls have visual styles Confused
oh and one more question .. how do i make that i'll see only password characters in my textbox?

and when i wanna check the text inside a textbox how can i get the text?
edit: nvm i got the text but i want to compare it with something and when i do that it does nothing even if the text is the same
Code:

char Password[255];
SendMessage(hPassword,WM_GETTEXT,MAX_PATH,(LPARAM)Password);
if (Password == "asd")
{
 //
 // etc ..
 //
}

for visual styles add this to the top of your project

Code:
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' "\
"version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

#include <commctrl.h>
#pragma comment( lib, "COMCTL32.lib" )


then in your WinMain add

Code:
INITCOMMONCONTROLSEX Init;
Init.dwICC = ICC_STANDARD_CLASSES;
Init.dwSize = sizeof(INITCOMMONCONTROLSEX);
InitCommonControlsEx(&Init);


To set the password char use the message EM_SETPASSWORDCHAR (http://msdn.microsoft.com/en-us/library/bb761653(VS.85).aspx)

use one of these functions:
GetDlgItemText
GetWindowText

or use this message
WM_GETTEXT

Edit for your edit:
You cannot compare a string like that in C++, you can only compare single charecters. so for strings Use the function strcmp (for ASCII) or _tcscmp (for UNICODE, included in tchar.h)

If the function returns 0 the string's are the same.

nice thx bro.
allthough i used the WM_GETTEXT message and i did got the text but when i compare it with other text i get nothing
it's like he's avoiding the "if" part

edit:
just saw your edit XD so i can use strcmp(str1,str2)?

not quite a bool, it returns 0 if there the same, i think it returns non-zero or -1 if there not the same.

example:

Code:
TCHAR tszStr1[50];
_tcscpy( tszStr1, _T("String 1") );
if ( _tcscmp( tszStr1, _T("String 1") ) == 0 )
{
    MessageBox( NULL, _T("Strings are the same"), _T("_tcscmp"), MB_OK );
}

my code goes like this:
Code:

char Password[255];
if (strcmp(Password,"aaa") == 0)
   MessageBox(NULL,"same","same",MB_OK);


but still it's avoiding the "if" part

try to add an "else MessageBox( NULL, "Not same", 0, 0 );"

and see if that pops up.

and does char Password contain any text? cuz if your declaring it right above then comparing it without assigning it a string or charecter then the function isn't going to return the same.

well it's really wierd this is my code for the comparing part if you wanna look at it:
Code:

      case WM_COMMAND:
         switch(LOWORD(wParam))
         {
            case IDC_CLOSE_BUTTON:
               PostQuitMessage(0);
               break;
            case IDC_LOGIN_BUTTON:
               char Password[255];
               SendMessage(hPassword,WM_GETTEXT,MAX_PATH,(LPARAM)Password);
               if (strcmp(Password,"123") == 0)
               {
                  MessageBox(NULL,L"YES",L"YES",MB_OK | MB_ICONEXCLAMATION);
               }
               else
               {
                  MessageBox(NULL,L"NO",L"NO",MB_OK | MB_ICONEXCLAMATION);
               }
               break;
         }
         break;

it's always go to the else part

instead of WM_GETTEXT do this:
Code:

if ( GetWindowText( hPassword, Password, MAX_PATH ) == NULL )
{
    MessageBox( NULL, "Fill in the box", 0, 0 );
}
else
{
  // do your check
}


it uses the WM_GETTEXT Message but its a bit easier to use.
