case ID_FILE_SAVEAS:
			{
				OPENFILENAME ofn;
				char szFileName[ MAX_PATH ] = "";
				ZeroMemory( &ofn, sizeof( ofn ) );

				ofn.lStructSize	= sizeof( ofn );
				ofn.hwndOwner	= hwnd;
				ofn.lpstrFilter	= "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
				ofn.lpstrFile	= szFileName;
				ofn.nMaxFile	= MAX_PATH;
				ofn.lpstrDefExt	= "txt";
				ofn.Flags		= OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT;

				if( GetSaveFileName( &ofn ) )
				{
					HWND hEdit, hTabs;
					hTabs = GetDlgItem( hwnd, IDC_MAIN_TAB );
					int curTab = TabCtrl_GetCurSel( hTabs );
					hEdit = vect[ curTab ];

					if( SaveTextFileFromEdit( hEdit, szFileName ) )
					{
						SYSTEMTIME st;
						GetLocalTime( &st );
						char dateTime[ 27 ];

						HWND hTabs = GetDlgItem( hwnd, IDC_MAIN_TAB );
						
						char drive[ _MAX_DRIVE ];
						char dir[ _MAX_DIR ];
						char fname[ _MAX_FNAME ];
						char ext[ _MAX_EXT ];
						
						_splitpath( szFileName, drive, dir, fname, ext );
						
						titem.mask	 = TCIF_TEXT;
						titem.pszText = fname;
						
						TabCtrl_SetItem( hTabs, curTab, &titem );

						sprintf_s( dateTime, "Saved: %d/%02d/%04d %02d:%02d:%02d", st.wMonth, st.wDay, st.wYear, st.wHour, st.wMinute, st.wSecond );
						SendDlgItemMessage( hwnd, IDC_MAIN_STATUS, SB_SETTEXT, 1, ( LPARAM )dateTime );
						
						ShowWindow( hEdit, SW_SHOW );
					}
				}
			}
			break;


Any suggestions as to why its not showing? For some reason the hEdit control decides to hide. - All my edit controls are stored in a vector named vect. - Status bar updates great with the date and time it was last saved.

If you comment this line same thing is happening ?
TabCtrl_SetItem( hTabs, curTab, &titem );

Yes, I've commented line by line testing it after i commented each part of the code and the error appears in the ShowWindow( hEdit, SW_SHOW ) line. Its weird too because before I had ShowWindow( vect[ curTab - 1 ], SW_SHOW ) and it worked great then I tried implementing something else into the code and now I cant seem to get it to work the way I had it. I deleted everything that I tried to implement.

Corection: It does stay visible, but the tab isnt updated with the new filename when commenting that one line: TabCtrl_SetItem( hTabs, curTab, &titem ); It also will show up when changing tabs, but for some strange reason it stays hidden once I save the file.

Update: I got rid of the TabCtrl macro and used this line:

SendMessage( hTabs, TCM_SETITEM, curTab, ( LPARAM )&titem ); and I'm getting the same result.

Well I've figured out a solution. Right after I set the tab control item text, I hid the edit control before I showed it. For some reason that works, but I'm confused as to why, so if anybody knows why that would happen, let me know please!!!
