How to check a string value read from an edit box

E2STE · #1 04-May-2005, 15:27

HI

Just started using mfc and am having problems reading a value that should be passed from an edit box.

I have created a 2 dialog boxes, 1 contains an edit box and a button.

I would like to do a check to see if anything has been written in the box and if it hasnt then i would like the other dialog box to be displayed saying, 'no string entered'.

I have assigned a member variable to the edit box called m_customerError

I have tried everything from if(m_customerError == ""), to if(IDC_CustomerError == "hello" and tried writing hello in, but when i debug to see what value has been recoded it just says ( "" ) so i think its not reading what im entering into the edit box.

My code is below, what do i need to write to check if anything has been entered?

CPP / C++ / C Code:

#include "customerError.h"

void CNewGUIDlg::OnSearchButton() 
{
	
	if( write check in here)
	{
		customerError Dlg; // second dialog box

		Dlg.DoModal(); //display dialog box
	}
	
}

I woud be very appreciative for any help.

Cheers ste.

CEdit* edit; // CEdit of the aforesaid editbox, initiate it with GetDlgItem func
edit->GetWindowText(strString);
if(strString.IsEmpty())
{
...
...
...
}

Hope it helps
