Related to edit boxes

[Taruni]

Hi, I am working with edit boxes.I have declared a member variable for it with data type as "CString" .Is there any event which rises at the time when the edit box looses the focuses(for eg stating that the range is not between 100 and -100) or alternatively I need some means to set the range for that edit box for which I have declared a variable of type "CString" . I will enter only numbers and not character type data.I will convert the entered data into integers later on.For the entered data I need to find whether it is in the range or not. Thanks in advance Taruni

You can set Min value and Max value for your control(editbox)_**

:) I thing it is better to add control variable for Edit box Instead of using CString as datatype, use CEdit. :) Dream bigger... Do bigger...Expect smaller aji

For that i think he need to add Control variable for the edit box instead of CString Dream bigger... Do bigger...Expect smaller aji

Then why CString? ;)

The EN_CHANGE notification message is sent when the user has taken an action that may have altered text in an edit control. Then you override the EN_CHANGE Event and write this code // where m_editbox is a variable associated to the edit window

char *myValue=new char[m_editbox.GetWindowTextLength ()];
m_editbox.GetWindowText(myValue,strlen(myValue));
int i=0;
i=atoi(myValue);
if(i>=100 || i<=-100)
{
	AfxMessageBox("Invalid value:");
}

I hope that I understood your query correctly Somethings seem HARD to do, until we know how to do them. ;-)_AnShUmAn_

You should be using CEdit instead. Otherwise, you'll be (incorrectly) using UpdateData(). See here for how/why that method can be avoided.
