I've a program that calls other dialogs.

However, it appears that I can only call one dialog at any one time.
The main dialog is disabled until I exit the second dialog.
I want to be able to call many dialogs without the main dialog being disabled.

Suggestions much appreciated

Kind Regards
Caoimh

CMydialog *pDlg;
pDlg = new CMydialog;
pDlg->Create(CMydialog::IDD);
pDlg->ShowWindow(SW_SHOW);

Do this for other dialogs also.

For futher reference you can checkout what modeless dialogs are.

I did a bit more research on modeless dialogs.

At the moment this code allows one to call a new dialog every time the button is pressed.

Would you by chance know of a routine which would solve this problem, i.e. I only want the dialog once, not many times.

Well you want many dialog box open and want only one of each dialog box to be open, its just a matter of programming logic.

CMyDialog *pDlg = NULL; //Some where global or in the theApp

if(pDlg == NULL)
{
pDlg = new CMyDialog;
pDlg->Create.....
...
}

When you destroy the window, i.e in OnDestroy
set pDlg = NULL;

hope this helps.

You'll need to use modeless dialogs instead of modal.

Hi,

I'm writing a MFC program at the momemnt. My program receives a string, but I want to output the hex version of the string to an edit box rather than the actual string.

Suggestions much appreciated

Kind Regards
Kevin

CString strEditText;
strEditText.Format("%x", atoi("2468"));
editctrl.SetWindowText(strEditText);

Do you mean a string representing a number? Or just the hex for an aribtrary string? Use atoi() for parsing a number. To convert an arbitrary string to a hex encoded string try something like this:

CString csYourString = "Something.";<br />
	CString csHex, csEditContents;<br />
	int i;<br />
	for (i=0; i<csYourString.GetLength(); i++)<br />
		{<br />
		csHex.Format("%02X", csYourString.GetAt(i));<br />
		csEditContents.Append(csHex);<br />
		}<br />

csEditContents will then contain "536F6D657468696E672E"

Is this what you meant?

The append method won't work, not a member of CString, any suggestions on a workaround

Oh well, stuff like Append() is the whole reason for having a class like CString.
You can write your own append code then. Its only a few lines.
