This code won't work. You'll get an error message saying that you're using an unknown class. You need to change
strcpy(className, "RICHEDIT_CLASS");
to
strcpy(className, RICHEDIT_CLASS);
I tried this and it worked fine.

Did you init richedit control??
if you use MFC, please try to call AfxInitRichedit() in App::InitInstance().
maybe that's the point.
|
|
|
|
|
No MFC. Just Win32.
-Tareq
|
|
|
|
|
try to use "InitCommonControlsEx();" in your InitInstance() function.
|
|
|
|
|
nope  its the same.
-Tareq
|
|
|
|
|
try
::LoadLibrary("Riched20.dll");
For win95 the rich edit control lib is "Riched32.dll",
for win98 win2k&winxp, the lib is "Riched20.dll"
|
|
|
|
|
tried that also ... i'm sure its some silly mistake. it cant be that complicated.
HINSTANCE hLib;
hLib = LoadLibrary("Riched20.dll");
if (!hLib)
{
hLib = LoadLibrary("Riched32.dll");
if (!hLib)
{
MessageBox(0, "Richedit control failed to initialize!", "Editor", MB_ICONERROR);
exit(0);
}
else
strcpy(_className, "RichEdit");
}
else
{
strcpy(_className, "RICHEDIT_CLASS");
}

Hi,
I'm looking for an easy way to test my embedded C code.
I have figured out how to get my C code complied into MFC VC6.0, now I would like to take the native C "printf" (for debugging) and display it in a MFC list or text box. I don't care which one
I'm only after debug output and being able to push MFC buttons.
Please help me with a simple way to do this. I'm not an expert C++ programer.

stupid question here?
where would I start to get an editbox receiving strings one line at a time to display the last line. example
1<br />
2<br />
3<br />
4<br />
5<br />
6<br />
7
right now line 6 and 7 are out of view in the editbox, but I want the editbox to show 6 and 7, and hide 1 and 2. In other words just auto display the last messages sent to the editbox.
thanks,

Did you try out CEdit::LineScroll(...)?
from msdn:
void LineScroll(int nLines, int nChars = 0);<br />
<br />
Parameters:<br />
nLines <br />
Specifies the number of lines to scroll vertically. <br />
nChars<br />
<br />
Specifies the number of character positions to scroll horizontally. This value is ignored if the edit control has either the ES_RIGHT or ES_CENTER style.

just use WM_VSCROLL like this:
::SendMessage(WM_VSCROLL,hWnd,SB_BOTTOM,0);
the hWnd is the handle of edit box;
good luck!

Hi,
Did any one know how to get a message in Visual C++ when a smart card was inserted or removed ?
Thanks Very much
|
|

I don't know the answer but asking the questions 3 times in two days isn't going to help you get an answer.
Why don't you just read all of the messages posted on this board for the last two weeks? I do that all the time and I seem to recall someone asking a question about how to detect new hardware inserted and registering your application for notification from the operating system.
As a last resort, do a search. Though, I know that can be hard getting the right keywords.

How to view in messagebox
sample file: http://dziennik.naczasie.pl/testfile.txt
if I try messagebox return only """
|
|
|
|
|
Load file contents to the string (CString or simply char*), then display it. Consider scrollable edit box or some decent UI instead of a MessageBox, unless the file is always small and formatted in a way that MessageBox can handle.
