Switching editboxes using tab

[goody11]

Hey,
I was just wondering how do I make my edit boxes so that when the the tab button is hit the cursor will go on to the next edit box in windows API. I've done some research on functions that deal with the cursor but I can't string them together to make something that works. Help please. Thanks.

[William Hemsworth]

Have you tried SetFocus?

[goody11]

Well yes, but how can I use that in order to do this?

[William Hemsworth]

If you use SetFocus on the handle to the text box, it should move the text cursor to there.
Just tried it, it worked.

[goody11]

How can I say, if the tab button is pushed, use SetFocus() ?
(I haven't dealt to much with code for saying if a certain button is pressed do something.)

[William Hemsworth]

How can I say, if the tab button is pushed, use SetFocus() ?

Show me your code.

Have you already programmed the functionality of the tabs? and do you have a HWND of the text box? If not, these are small details I can still help with.

[goody11]

I'm not sure how to create the functionality of the tabs.

[goody11]

Here is the best thing that I could come up for the tab functionality but it still doesn't work.

case WM_CHAR:
			switch(LOWORD(wParam2))
			{
				case 0x09: 
				{
					HWND hmove = GetDlgItem(hwnd2, IDC_POSTEXT);
					SetFocus(hmove);
				}
				break;
			}
		break;

[goody11]

Actually here's the code to the entire dialog Procedure:

BOOL CALLBACK DlgProc2(HWND hwnd2, UINT Message2, WPARAM wParam2, LPARAM lParam2)
{
	switch(Message2)
	{
		case WM_INITDIALOG:
			// This is where we set up the dialog box, and initialise any default values

			SetDlgItemText(hwnd2, IDC_STEXT,     "    Spanish");
			SetDlgItemText(hwnd2, IDC_ETEXT,     "    English");
			SetDlgItemText(hwnd2, IDC_POSTEXT,   "Part of Speech");
		break;
		
		case WM_CHAR:
			switch(wParam2)
			{
	                case 0x09:  // tab 
                       {                          
                           HWND hmove = GetDlgItem(hwnd2,IDC_POSTEXT);
                           SetFocus(hmove);
                        }
			}
		break;

		case WM_COMMAND:
			switch(LOWORD(wParam2))
			{
			case IDC_AWA:
			{
				int length = GetWindowTextLength(hRetrieve);
				LPCSTR pszText = "á";
				SendMessage(hRetrieve, EM_SETSEL, length, length + 1);
				SendMessage(hRetrieve, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_EWA:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "é";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_IWA:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "í";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_OWA:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "ó";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_UWA:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "ú";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_NWT:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "ñ";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			break;
			case IDC_UQ:
			{
				HWND edit = GetDlgItem(hwnd2, IDC_ANSQW);
				int length = GetWindowTextLength(edit);
				LPCSTR pszText = "¿";
				SendMessage(edit, EM_SETSEL, length, length + 1);
				SendMessage(edit, EM_REPLACESEL, true,(LPARAM) pszText); 
			}
			case IDC_SAVE:	
				DoFileSave(hwnd2);
				EndDialog(hwnd2, 0);
				hwndGoto = NULL;
			break;
			}
		break;
		
		case WM_CLOSE:
			EndDialog(hwnd2, 0);
			hwndGoto = NULL;
		break;
		
		default:
			return FALSE;
	}
	return TRUE;

OK, after some research I figured out that I could use WS_TABSTOP but it's still not working. I have condensed my Program down so that you can see somewhat of the full code that I am dealing with.

If it's the default tab-control, then your event handler should look somewhat like this:

case WM_NOTIFY:
      {
        HWND tabs = GetDlgItem(hDlg, IDC_TABS);
        switch ( ((LPNMHDR)lParam)->code ) {
          case TCN_SELCHANGE:
            {
              selectedTab = TabCtrl_GetCurSel( tabs );
              // Code here
            }
            break;
        }
      }
      break;

But looking through your resource code, I don't see any sign of a SysTabControl32 box, what are you using for your tabs?

[goody11]

I'm not following your code very well, could you please explain it? And shouldn't the tab stop style fix my problem because from the research that I've done, It should do exactly what I want it to. Do you know why those tab stops aren't working.

[goody11]

Never mind. I figured it all out. Thanks for all of your help. I had to use the IsDialogMessage function properly.
