UpdateData(FALSE) refresh all members values into the linked controls.<br />
<br />
So be carefull if you want to upgrade only one control, it is more secure to do this (in order to record any user changes) :<br />
UpdateData(TRUE); &nbsp; // Retrieve values from control<br />
m_message=myvalue;<br />
UpdateData(FALSE); &nbsp;// Refresh m_message<br />
<br />

I have just started with Visual C++.<br />
<br />
I have created a MFC application Diaglog. On the form I have created a Edit box.<br />
<br />
I have assigned the the control's the following ID's <br />
IDC_user_message<br />
<br />
Using the Class wizard I have assigned a member variable m_message using the class wizard. <br />
<br />
In the code I want to make the edit box display some text that I will hard code. <br />

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
