Re: How to implement Tab order to the controls in a MFC Dialog box

If you are using resource editor, you can set the tab order there. It is available in "Layout" menu in VC6 and "Format" menu VC9. Shortcut key is Ctrl + D (in VC6 keyboard shortcut map). Then you can see the tab order indication for all controls. You can click on each controls to sequence.

If you are creating the controls dynamically, the creation order sets the tab order. You can change it by using SetWindowPos().

Hi ns Ami,

I am creating dynamic edit box in Group Box. My current Tab order is Group Box, OK, Cancel button. Now I want tab order as:
Group box-> Edit Box 1 -> Edit Box 2 -> Edit Box 3 -> OK -> Cancel.

How can i achieve this? do you have any idea?

Anshul

I presume that "dynamic edit box" means you are creating edit box dynamically at run time. If so, you can use SetWindowPos API to set the Z-order of edit control. You will get more information from the API documentation. The parameter hWndInsertAfter (or pWndInsertAfter in the case of MFC) can be the window handle of control, which is needed to be before in tab order.
For example,
m_edit2.SetWindowPos( &m_edit1, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZER | SWP_NOACTIVATE );
This will set the tab order as edit1 -> edit2.

Hope this info will help.

Hi Ami,

I am creating edit box in Group box as:

#define ID_CURRENT_SN_EDIT  2000

m_gbGroupBox = (CStatic*)GetDlgItem(IDC_GROUPBOX);
int pointY = 0;
int i = 0;

for (int x = 0; x < m_vecpData->size(); x++, i++)
{
  pointY = 30 + (i * 35);
  m_ceEdit = new CEdit;
  m_ceEdit->Create(WS_VISIBLE| WS_BORDER |ES_READONLY | WS_TABSTOP, CRect(10, pointY, 130, pointY + 25), m_gbGroupBox, ID_CURRENT_SN_EDIT + i);
  m_ceEdit->SetWindowText(m_vecpData->at(x).c_str());
  m_ceEdit->SetWindowPos(m_gbGroupBox, HWND_BOTTOM , 10, pointY, 130, pointY + 25, SWP_NOSIZE); // This line is not working.:confused:
  m_ceEdit->ShowWindow(SW_SHOWNORMAL);
}

In this case the tab order will be same as the creation order. So no need to set the Z-order again. Anyway, is this a compilable code? Argument count of SetWindowPos seems as wrong.

Note that you are creating edit control as child of that GroupBox (a static control, i think). In that case the tab key navigation will not enter to the controls inside the GroupBox. Applying WS_EX_CONTROLPARENT style to GroupBox will help you.

For instance,
m_gbGroupBox->ModifyStyleEx( 0, WS_EX_CONTROLPARENT );

This is my modified compilable code but tab order is not working as GRPBox -> Edit 1 -> Edit 2 -> Edit 3 -> OK -> CANCEL.

It is still working as GRPBox -> OK -> CANCEL.

#define ID_CURRENT_SN_EDIT  1003

m_gbGroupBox = (CStatic*)GetDlgItem(IDC_GROUPBOX);
m_gbGroupBox->ModifyStyleEx( 0, WS_EX_CONTROLPARENT);

m_btnOK      = (CButton*)GetDlgItem(IDC_OK);
m_btnCancel  = (CButton*)GetDlgItem(IDC_CANCEL);

int pointY = 0;
int i = 0;

for (int x = 0; x < m_vecpData->size(); x++, i++)
{
  pointY = 30 + (i * 35);
  m_ceEdit = new CEdit;
  m_ceEdit->Create(WS_VISIBLE| WS_BORDER |ES_READONLY, CRect(10, pointY, 130, pointY + 25), m_gbGroupBox, ID_CURRENT_SN_EDIT + i);
  m_ceEdit>SetWindowText(m_vecpData->at(x).c_str());
  int nCtlrID = ID_CURRENT_SN_EDIT + i;

  if (x > 0)
  {
    CEdit* pEdit = (CEdit*)GetDlgItem(nCtlrID - 1);
    m_ceEdit->SetWindowPos(pEdit, 10, pointY, 130, pointY + 25, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE );
  }
  m_ceEdit->ShowWindow(SW_SHOWNORMAL);
}

Any Help or Suggestion!! I do not know what to do now.

Well, you missed WS_TABSTOP style.

And the following is not needed...

Hey Ami,

Thanks a lot for your valuable suggestion. It is working now. great :) !!!

Now my another task is:

There is one Static GRPbox which has been created in CFormView by using ToolBox. Now in Static Groupbox, I am creating "n" number of dynamic GrpBox. In Dynamic GrpBox, I am creating dynamic Edit Box (few are READ ONLY too).

Now I have to set taborder for that also. Any suggestion on this.?

Regards,
Anshul

I believe that, since you could understand your first solution well, you can implement this easily. Smile | :)

Or, are you in any trouble with that?

Well, In first round it is working but once it comes to OK or CANCEL button is not going back to edit box.

I am trying for that...

I will post code after few minutes or if you do have idea of why is it not coming back to edit box, you can let me know..

how to get the full length of the string that contains 0's inbetween.
I tried _tcslen() on the LPCTSTR, but it gives the string len till the first occurrence of a 0.

TIA

But in that case, how will you find the end of the string?

Are you talking about a 0 or a NULL present in your string.
If it's a 0, it shouldn't be a problem.

You need to google first, if you have "It's urgent please" mentioned in your question.

you may try this :

CString strTemp;
---
--
--
// if you need length of string
strTemp.GetLength ();

In this case how do you know the end of string?

In this manner, normally the last string will be ending with two consecutive nulls (0s). Is your string so?
