Error in getting Handle of editBox?
-
Hi All, In my project I want to get the string value set in text box. So I write following code as CEdit *pOpenEdit = (CEdit *) GetDlgItem(IDC_FOLDER_PATH); if( NULL != pOpenEdit->GetSafeHwnd()) { pOpenEdit->GetWindowText(buff,256); } In the above code I did not get handle of edit box. What is wrong in this code. Please send me solution if anybody have. Thanks Om

What happens if you run this code?
CWnd *pwnd=GetDlgItem(IDC_FOLDER_PATH);
pwnd->GetWindowText(buff,256);Or if you declare a variable for editbox
m_Edit.GetWindowText(buff,256);
or if you use of
WM_GETTEXTmessage ? -

/* I'm not sure what your having trouble with. However, I am confused what your using the handle for? Do you realize that your trying to use a pointer before you've even checked that it is valid? */ void CTest712Dlg::ShowEditText() { if (::IsWindow(m_hWnd)) { CEdit* pOpenEdit=(CEdit*)GetDlgItem(IDC_FOLDER_PATH); if (pOpenEdit) { CString sText(""); pOpenEdit->GetWindowText(sText); TRACE("%s\n",sText); } } } void CTest712Dlg::OnButton1() { // TODO: Add your control notification handler code here ShowEditText(); }

Use ClassWizard (Ctrl+W) to associate a
CEditvariable with theIDC_FOLDER_PATHcontrol. Then use itsGetWindowText()method.

Are you sure id of editbox is correct and what happens if you declare a variable for it did you can values of edit control.

Hi Hamid, ID of Edit box is correct, because by using same ID i get the pointer for setting value to the window. CEdit *pOpenEdit = (CEdit *) GetDlgItem(IDC_FOLDER_PATH); if( NULL != pOpenEdit->GetSafeHwnd() ) { if( strOpenPath != "" ) pOpenEdit->SetWindowText(strOpenPath); } This code is execute well but in following code i did not get the handle. CEdit *pOpenEdit = (CEdit *)GetDlgItem(IDC_FOLDER_PATH); if( NULL != pOpenEdit->GetSafeHwnd() ) { char buff[500]; pOpenEdit->GetWindowText(buff,256); strOpenLocation = buff; } In this code I did not get handle so it is not entered in if block. Let me know what is wrong in this code. Thanks in Advance Om

I have a question why you didnt declare a variable for edit control instead handle to it?
