If you have the window handle and the control IDs, you can just gather or set the data like in your own dialog. E.g.<br />
<br />

<pre><code id="code-20-39249102-1">#define ID_TEXTFIELD 1234 // finding that is the tricky part
HWND hwnd = FindWindow(NULL,_T(&quot;Dialog Title&quot;));

TCHAR acText[256];

GetDlgItemText(hwnd,ID_TEXTFIELD,acText,256);</code></pre>
</div>

Ok, let me elaborate a bit...<br />
<br />
My main dialog is defined as IDD_DIALOG1<br />
<br />
I have another dialog ( which is not shown until a button is pressed ) defined as IDD_DIALOG2<br />
<br />
Inside of IDD_DIALOG2 is a textfield, defined as IDC_PRINT.<br />
<br />
Question:<br />
<br />
How do I retrieve IDC_PRINT from IDD_DIALOG1?<br />
<br />
Could I copy the value of IDC_PRINT to a global variable, and simply access it that way from IDD_DIALOG1? If so, how?<br />
<br />
Thanks!

Question:

How do I retrieve IDC_PRINT from IDD_DIALOG1?

Could I copy the value of IDC_PRINT to a global variable, and simply access it that way from IDD_DIALOG1? If so, how?

<div class="content wysiwyg-content">
My application is a Dialog box. Within my app, there is a button, which when pressed another dialog appears. <br />
<br />
My questions is, am I able to access Global Variables from here, and can I access controls as I normally would?<br />
<br />
For instance, from the second dialog, I want to check the contents of an edit field in the first one.<br />
<br />
Thank you

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
