Damn! I can't remember it, but there was some way to subclass the edit box of a combo! I'll look for it, but I bet someone else will answer ya before I can dig it up

A million thanks. I was just about to dive into deriving a my own combobox class and then subclassing my edit control in my new combobox ctrl. This is much 'classier'

String resources are weird. Strings are stored in blocks of 16. IDs 0-15 are block 0, 16-31 are block 1, etc. So block# == ID >> 4. Use the block # to load the resource (with Find/Load/LockResource APIs). Once you get the block loaded, the format of the block should be obvious (Unicode strings, length-prefixed).

I've tried my own little replica of Chris' Creating Custom Controls, but whenever I add it to my project, the program simply fails to load, with no error or display of any kind. Has anybody had this problem, and how did they resolve it? I don't know where in the source my problem could be, and I shouldn't post the whole thing.
Thanks,

I've been there. It was a while ago, but I think it had to do with the message pump.
Make sure that you're handling your messages to the custom control correctly.

Ok. Thanks very much for the reply and the help. I'll look at the messages and go from there.

Could you please perhaps report back if this was the correct solution later on?
I Would be delighted to know that I've helped someone.

Gladly.
I took another peek at the message handlers but couldn't find anything obviously wrong. I decided to take another crack at it from scratch, and this time the program loaded, and my custom control was visible. I *think* the problem I introduced originally was due to misreading Chris' article and trying to simultaneously implement the control as one you can add in with the resource editor, AND one that you manually Create(). I think for some reason this simply caused the program to not load.
Anyway, I continued to work on it and have made progress on this control (which I need for an app I'm working on--yes, it's supposed to be like the Task Manager grid control thingy). What a difference being able to see the program makes!
Thanks for the help,

Could anyone point me in the direction of an example or suggest a way to do an error log view in MFC?
I need something similar to Visual Studio's build output - a read only text output.
Should I derive a class from CEditView or CRichEditView or is it better to roll my own via CScrollView? I don't need anything too fancy (e.g. colours, fonts etc.) as it's just for an in-house tool that I'm writing.
Thanks for your help,
Marc

I did it without MFC, I just created an edit box and made it read only. It's one of the flags you can set for an edit box.

Thanks Christian but it's not quite what I want.
I'm using the doc/view architecture so I want it to be a view not just an edit box.
I've changed the flags of the edit view before and it's ok but I was wondering if there was a better way without having a greyed background and a cursor (caret) on screen.
Any ideas?
Marc

You can hide the caret - I did. As for the rest, mine did not go grey, if yours is, try handling key presses yourself in the view and discarding them. This has the advantage that you could accept certain keys to, for example, clear the view.

It's gone grey for me!
The method I'm using to set readonly is:
void CLogTextView::OnInitialUpdate()
{
CEditView::OnInitialUpdate();
// TODO: Add your specialized code here and/or call the base class
CEdit &edit_ctrl = GetEditCtrl();
edit_ctrl.SetReadOnly();
}
This makes the view go grey! Any ideas how not to leave it white?!
Also, do you know which methods hide the caret?
Thanks for your help,
Marc

As I recall, there was a hide caret function I called in set focus. I dunno why your view is grey, but as I said, if you leave that and instead catch WM_KEYDOWN, WM_KEYUP and WM_CHAR and don't call the base class, you'll get what you are after.

Cheers Christian.
That works a treat.

Ah, but there is one problem.
Whenever I add text to the edit control it seems to notify the Document and hence asks me if I want to save my changes when I go to quit out. Any idea how to stop this?
Marc

|
|
|

I did not use Doc/View. The Document has a dirty flag - set it to false as you close and you won't get that prompt. I forget it's name though.

Yes, I could do that but I won't know whether the rest of my code has properly modified the document or not.
Is there no way to stop the edit control from telling the document that it is being modified?
Marc
|
|
|
|
|
In the code that updates the edit control, check if the flag is set to dirty. If not, then reset it to not dirty after doing the update.

I am creating server based multi client chat application. In this regard i like to ask a question. I hope that "experienced" people will answer these easily. Remember that the application is very simple. A client just send text message of certain size to another via server. Server will run on Win2000 machine in StandAlone environment. Please answer the following question:
What do you think the maximum number of sockets my server create on accepting connection. Or in other words
considering the work load as i given in above paragraph, what do you adive me about the maximum number of sockets descriptors i create on my server.
