I use VC++6.0 to create SDI project, my View base on CEditView class. I print out to view a string by GetActiveView()->SetWindowText(CString str), str = str + addstr. The cursor always on top of view. I want the cursor go to end of string str, or view scroll to bottom when I update str.
How to do that ? please help me.
thank !

Surely it isn't the most efficient way, but I use this and it works!
<br />
this->GetEditCtrl().SendMessage(WM_HSCROLL,SB_LEFT);<br />
this->GetEditCtrl().SendMessage(WM_VSCROLL,SB_BOTTOM);<br />

I try your way:
this->SendMessage(WM_HSCROLL,SB_LEFT);
this->SendMessage(WM_VSCROLL,SB_BOTTOM);
and
GetActiveView()->SendMessage(WM_HSCROLL,SB_LEFT);
GetActiveView()->SendMessage(WM_VSCROLL,SB_BOTTOM);
but nothing change.

You'll need to call GetEditCtrl() first.

Hi,
I have an application running and I have created a modeless dialog box, named it Log window.
I need this dialog to display in it's edit box, all the log information that the actual application sends.
eg:
The actual application opens files, writes to it, closes it.
The log windows should print "File opened succesfully", "abcd data written to file", "File closed" etc.
With whatever info I have, I think I will create some thread which will continuously read a global CString and keep updating the edit box in log window. But, will this slow down the application as the thread is continously reading the string.
Another option is to call a update_log() function after each operation and this function updates the log.
These are just ideas and I am not very sure of how to implement these or anything better.
Is there a better method . how ??
please help!!

Hello.
I suggest you do like this:
Prepare the text line (to be logged) in your main program.
Send it to the modeless dialog by means of a SendMessage-command.
Set the message ID to something higher than VM_USER, in order to aviod conflict with the ordinary Windows messages.
Track that message ID in the modeless dialog and display the text.

""Prepare the text line (to be logged) in your main program"" - OK
""Send it to the modeless dialog by means of a SendMessage-command."" - not familiar with SendMesage - will find out.
""Track that message ID in the modeless dialog and display the text."" - How. Should some thread be running to display the meesage whenever a new message comes?

As far as i understand if u want to have
every minute update in the Log Screen (dialog)
then u need to have a dedicated thread working
behind it .
A thread wont be so costly for this work just
u need to suspend the thread for some small time
if it aquires more resources.
else SendMessage is fine

Hello.
I assume your modeless dialog has got a Windows message loop.
If that's the case, then the logging text will come as a message in the standard message loop.
So all you have to do in the modeless dialog, is catch the specific ID (the ID you gave when you sent the logging message), get the message and then display it.
There is no need for an explicit thread in your modeless dialog.
I'm sure it will get clearer as you investigate the SendMessage func.
Unfortunately, I don't have the time to give you an example.
But search in CP for SendMessage, I'm sure you will get a lot of hits on the subject.
Good luck.

I got it working. Thanks a lot.
BTW, in class wizard, I could not see OnMessage(). I had to type manually in MesageMap. Why ?

Great! That's the way to do it.
I don't know why MS have hidden OnMessage in ClassWizard.
Keep up the good programming!
Kakan.

Probably because the message you wanted to process is unknown to ClassWizard.

Can anybody tell me how can i acces the first bytes at the entrypoint of an exe. I know the PE layout, format, but i don't know how i can translate the entrypoint to fileoffset and HOW i read those bytes?
I'm waiting for any kind of suggestion (or sample code).

What are you trying to accomplish by modifying an EXE directly?
I can't think of a valid reason for doing so, especially wanting to modify the entry point. Your post (and the previous one) sounds like you want help writing a virus.

I want to write a tool like PEid's PE signature viewer. A tool for compiler detection (by signature bytes).
|
|
|
|
|
Does this tool detect the compiler or the linker?

this tool will try to detect the compiler (and the cryptor or exe modifier)
|
|
|
|
|
I know the linker writes information to the EXE that can be retrieved, but are you sure that the compiler does too?

I only know that every exe has a signature bytes at the entrypoint of the exe. (i mean that the first 128 bytes at the entrypoint are the signature bytes, they help to identify the compliler). And these signature bytes are modified by the protectors, packers.
