changing caption of static text control

Pandiani · #1 18-Sep-2004, 17:07

Is it possible to change caption of static text control in Visual C++ .Net in runtime. For example if user click on button caption on some static text control is changed. I declared CStatic variable named m_Text but dont know what to do next. Static text field has ID: IDC_TEXT

Code:

void CPlotDlg::OnBnClickedButton1()
{
	m_Text.???
}

Thanks for help!

You can go 2 ways about this.
1. Do what you did, and than add this line in the data exchange section of your dialog:

CPP / C++ / C Code:

DDX_Control(pDX, IDC_TEXT, m_text);

Now your dialog is ready to exchange data with your control.
Than, in your button's OnClick event:

CPP / C++ / C Code:

void CPlotDlg::OnBnClickedButton1()
{
	m_Text.SetWindowText("I'm a static control");
}

However, IDC_TEXT might be defined as -1. In this case, define it in Resource.h with a different value - don't cae what that is, just something you didn't use for another control (>0, howerver).

2.(Recommended)
Declare a member variable of your dialog as a pointer to CStatic:

CPP / C++ / C Code:

CStatic *Label;

Then, in your OnInitDialog, attach it to your dialog:

CPP / C++ / C Code:

Label = new CStatic;

Label->Create("I'm a static control too", WS_CHILD | WS_VISIBLE,
	          CRect(10, 40, 160, 80), this, 90210); //Beverly Hills :D

Change it's caption:

CPP / C++ / C Code:

void CPlotDlg::OnBnClickedButton1()
{
	Label->SetWindowText("I'm a changed static control");
}

Mental Note: I should write a small tutor about data exchange and populating text controls sometime, since many people don't find it obvious the way that VC treats this controls. As a side note, I completely understand this, since I found it too confusing, and I think MS didn't find the best and most user-friendly way to handle the implementation of this controls.

Hope this is what you were looking for.

Best regards,
Luci
