OnChar

[mpsoutine]

Hi All,

Not sure if this is the correct function to do this in. I'm trying to take a character in an one edit box, convert in to uppercase, and print it in the original edit box and also a surname edit box. Get following error message:
The instruction at "0x5f42e11a"referenced memory at "0x00000020". the memofy could not be "read".

MPSoutine.

You will need to post the relevent code.

Hi,

I aggree. I thought I did the cut and paste correctly.

MPSoutine

void CInitials::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default

CEdit::OnChar(nChar, nRepCnt, nFlags);

CEdit* pEditInitials =(CEdit*)GetDlgItem(IDC_EDIT_INITIALS);
CEdit* pEditSurname = (CEdit*)GetDlgItem(IDC_EDIT_SURNAME);

CString strText;

//**Retrieve the text from the "Initial" edit box

pEditInitials->GetWindowText(strText);

//** Update the context of the surname edit box

pEditSurname->SetWindowText(strText);






if(isalpha(nChar))
{
if(islower(nChar))
nChar -=32;

//**Call the default window procedure as the value of nChar
//**may have been altered

DefWindowProc(WM_CHAR, nChar, MAKELONG(nRepCnt, nFlags));

//**Call the default window procedure again to add the p[eriod

nChar = '.';
DefWindowProc(WM_CHAR, nChar, MAKELONG(nRepCnt,nFlags));


}

//** If the backspace key is pressed call the
//** base class function twice to remove the period
//** and the letter

if(nChar == VK_BACK)
{
CEdit::OnChar(nChar, nRepCnt, nFlags);
CEdit::OnChar(nChar, nRepCnt, nFlags);
}

}
