Hi.

If you use SPY++ to check the content of a edit box, it is always
"" even though edit box has some string.

I have the same problem and use copy() and paste() of CEdit class.
That is, after you make some edit box of your dialog, you can
copy and paster the same string from the target edit box to your
edit box.After this, you can use GetWidnowText() to your program.

Hope for help.

It's useless.
After all,when the eidt control's style is ES_PASSWORD,You can't copy them. In the other hand,GetWindowText() only get the edit content belong to the same application.
//sigh.
Have another good Idea?

Hi.

What means "useless"?

I made this program to read type name and value name of html
on the dialog of MS FrontPage. And it works fine.

Because I didn't use to read the password like "*****". I didn't
confirm this.

If you want to use copy(), you need set SetSel() cover all string.
Actully, I try to find the other approach, but in vain.

If someone knows the other solution, please tell us.
I have many things to do, Java RMI and so on. I'm not interested in
this topic anymore.

GetText only get's the title of the window if passed a window handle and the title of the edit control if passed a handle to an edit control

to actually get the text contained within an edit control you need to send the WM_GETTEXT message using SendMessage()

read up abou tthese two things in the msn help files (you really should have Visual studio if you are going to be developing windows applications, in which case all the info you need is there - do a help search for these things)

good luck

John.
