Edit Box from funtion
-
Hello! I am new to MFC. I want to change an Edit Box from a function! The situation is the following (simplified):
int function(); //Prototype void TestDlg::OnGo() { SetDlgItemText(IDC_Output, "From OnGo!!!"); //Works fine function(); // Call my function } int function() { SetDlgItemText(IDC_Output, "From funtion()!!"); // ERROR }So, the output from the function does not work. I know, I have to append something, but what????? -

function()a member of of your TestDlg class. or, 2. You need to pass handle of dialog window (HWND) toSetDlgItemTextas first parameter, infunction:SetDlgItemText(hWnd, IDC_Output, "From funtion()!!");
You may pass this handle to
function. This handle is member of TestDlg class with namem_hWnd. ARSALAN MALIK -

Doesnt work, GetDlgItem() asks for Window Hande (doesn't accept 1 Parameter)! How can I get this? WoodStock
Their are two versions of GetDlgItem. 1. The SDK version needs two param 2. The CWindow::GetDlgItem and CWnd::GetDlgItem needs 1 param. Are you getting some compiler errors ?. Regards Alpha

function()to:int TestDlg::function()
{
...
}and don't forget to add the prototype to the class. Don't use
SetDlgItemText(). Use ClassWizard to create a control variable (CEditin this case) and use theSetWindowText()method to change the text.
