IDC_STATIC Problem?

Hallo all,
I have a problem with changing text for IDC_STATIC. I have 1 Combobox, 1 button and 1 idc_static text in my dialog. For initializing, everything worked quite well. Now after clicking the button, I want to update the new text for the idc_static and also for the combobox. It worked for the combobox but for the static text, it didn't work, and I don't know why. Can somebody help me?

Thank you very much

DDX_Text(pDX, IDC_STATIC_RPA_STATUS, m_strRPAStatus);	
DDX_Control(pDX, IDC_COMBO_STATE_REASON, m_StateReasonCtrl);
 
m_pParentWnd->GetRpaProps()->m_strRPAStatus = StringFromVar(pRpaTab->GetFieldValue("Status")); ---> it didn't work
// CString Status = StringFromVar(pRpaTab->GetFieldValue("Status"));
// SetDlgItemText(IDC_STATIC_RPA_STATUS, Status);              ---> this also didn't work
m_pParentWnd->GetRpaProps()->m_StateReasonCtrl.SetCurSel(nID); ---> it worked perfectly

The following is one possible solution:

1. Declare m_strRPAStatus as a CStatic member variable:

CStatic m_strRPAStatus;

2. Use the following macro:

DDX_Control(pDX, IDC_STATIC_RPA_STATUS, m_strRPAStatus);

3. To update the text call the following line:

m_strRPAStatus.SetWindowText(_T("New text"));

Hallo LordOfPorts,
Thank you for your quick reply, I will test it again, but I am still wondering, it worked at the 1st time opening the dialog, why didn't it work after clicking the button on this dialog?
Regards

Actually it will work if you call UpdateData(FALSE); after changing the value of the CString variable.
m_pParentWnd->GetRpaProps()->m_strRPAStatus = StringFromVar(pRpaTab->GetFieldValue("Status"));
UpdateData(FALSE);

Hi LordOfPorts,
I already tried UpdateData(False); and it didn't work :-(
I am still thinking about your 3 ways above, because if I change the type of the variable, I have to change my whole program, and it will take much time :-(
Do you have any other idea?
Thank you very much

I did exactly in the way in your 1st post, but there was Debug Assert Error at the 1st time opening the dialog :-(

ASSERT(::IsWindow(m_hWnd));
m_hWnd == NULL

IDC_STATIC is a generic ID for static controls.  To do what you want you need to define a unique  ID for each static control you want to manipulate the text of.

rambovn, you mentioned that with CString it had worked during the dialog initialization so you have already correctly set the ID of your CStatic control to IDC_STATIC_RPA_STATUS, correct?

I have tested the first solution with mapping to control to a CStatic member variable as well as using UpdateData(FALSE); when the member variable was of CString data type successfully so let's check the configuration one more time assuming you are using the CStatic member variable approach from the first post, i.e. how does the OnInitDialog() look like? It would be something like:
BOOL CYourDialogDerivedClassDlg::OnInitDialog()
{
	CDialog::OnInitDialog();
 
	// ...
 
	// TODO: Add extra initialization here
	m_strRPAStatus.SetWindowText(_T("Original Text"));
	
	return TRUE;
}

...and just to also confirm, you have replaced the following line:

DDX_Text(pDX, IDC_STATIC_RPA_STATUS, m_strRPAStatus); // when mapping CString

with:

DDX_Control(pDX, IDC_STATIC_RPA_STATUS, m_strRPAStatus); // when mapping CStatic

(Was the text set in the resource editor ?)


The question is not very clear about how the dialog controls are (ID, initial caption)

To Andy: My ID is already unique, it already worked for the initialization. It didn't work only when I clicked the button on the same dialog.
Can you explain your question "Was the text set in the resource editor" more clearly? Thank you very much
To LordOfPorts: I already did like the way you wrote, but it didn't work also for the inialization so I changed it back
I attached my code again

Ok, so m_strRPAStatus is a member variable of the CRPAProperties class and OnRPAProperty is a member method of the GPSView_Fen. Try calling UpdateData(FALSE); from GPSView_Fen::OnRPAProperty() in the following manner:
m_pRPAPropsDlg->m_strRPAStatus = StringFromVar(m_pRPAPropsDlg->m_pRPATab->GetFieldValue("Status"));
m_pRPAPropsDlg->UpdateData(FALSE);

It worked quite well until I go to the function: void CRejectRpaReason::OnOK()

You need to call the UpdateData method of the window to which m_strRPAStatus belongs because it is mapped to a CString variable. With the combo box you are calling m_pParentWnd->GetRpaProps()->Invalidate(); which takes care of this for you.

Can you display the value of the m_strRPAStatus variable after setting it, i.e. in the code above:

m_pRPAPropsDlg->m_strRPAStatus = StringFromVar(m_pRPAPropsDlg->m_pRPATab->GetFieldValue("Status"));
AfxMessageBox(m_pRPAPropsDlg->m_strRPAStatus);

Is it the correct new value?

yes it is correct :-(, my problem was so strange for me :-(
OnRPAProperty worked perfectly until now, the problem comes from this function (see the line that is bold), and I already checked the value of " m_pParentWnd->GetRpaProps()->m_strRPAStatus", it is also correct, but why didn't it appear on the dialog?

                pStateReasonTab->SetFilter("");

                {
                        m_pParentWnd->GetRpaProps()->m_strRPAStatus = StringFromVar(pRpaTab->GetFieldValue("Status"));
 
                //      m_pParentWnd->GetRpaProps()->m_strRPAStatus.SetWindowText(StringFromVar(pRpaTab->GetFieldValue("Status")))  ;

Can you try:

instead of:

What do you mean by initialisation?
Do you design the dialog then put some text into the static control in the resource editor?  eg. "This is my combo->"

To Andy: I created the dialog, and by opening it at the 1st time, the static text is filled by the value that I got from the database.
After that, I clicked one button named Reset on this dialog, and tried to fill the static text with the new value, it didn't work. That's what I meant for initialization.
To LordOfPorts: it didn't work.

Thank you very much for your help.

I just want to give up :( But I have to solve it :-(
