hey, just a tiny problem:

i use a CDialog with a couple of CustomCtrls arrange vertical. My CustomCtrl uses a CToolTipCtrl to display ctrl states.
When the Tooltip appears the control "under" the tooltip would not be repainted up to to the time the dialog call invalidate or the control gets the focus.

How can I solve that problem?

Hi,
I want to open multiple childs windows inside one of the childframe window of an MDI application. Any idea about how to achieve this?.

Details is like below:

I have my mainframe window derived from CMDIFrameWnd. Now in one of the childframe ( derived from CMDIChildWnd ) I want to open mutiple child windows i.e my child frame should behave as a parent to another child windows. Please let me know how to achieve this.

Any sample would be of great help.

Thanks,
Amit

The classic point to create child windows would in your CChildFrame::OnCreate handler.
I know the CSplitterWnd stuff goes there. You can also add toolbars etc at that point.

Have a wierd one. One of our customers recently purchased a new computer with XP PRO installed. Out software prints fine on others customer's pcs running XP PRO, but this one wants to print everything upside down and backwards. Has anyone ever seen this happen. Would appreciate anyone's input.

Have you tried putting the paper in the other way around? Big Grin | :-D

More seriously, I would look at differences in printer / printer drivers rather than XP.
I used to have a lot of problem with Epson drivers when HP ones worked just fine.
Does the problem happen when you change printers? Does it happen on a known-good-system
with the suspect printer?

Does the issue happen if you print from another application? Or just yours? I usually
use Wordpad as a simple should-be-fine application.

Is it just an (obsure) option in the print setup?

This is likely some really obscure print driver option that is running amuck, but if you solve it, I'd love to hear the reason. This sounds like a great trick to play on some of my evil co-worker's PC. :mwaahaaha: Smile | :)

Compiling C++ in .NET 2003

I have just compiled an old VC6 project in VS.NET 2003 and I am getting some odd errors. It's been a while since I did any C++ and am a bit rusty so any help would be appreciated.

In the following code:

template<class T> class COpList <br />
{<br />
public:<br />
<br />
	COpList();  <br />
	~COpList();<br />
<br />
	bool ParseList(CTokenizer&);<br />
	void StartIterator(void) const;<br />
	const T* GetOp(void) const;<br />
<br />
	void Display(ostream&) const;<br />
	string GetAsText(void) const;<br />
<br />
private:<br />
<br />
	void AddOpListElement(const string&);<br />
<br />
	typedef vector<T*> OPVEC;<br />
	OPVEC m_vecOpList;<br />
	mutable vector<T*>::const_iterator m_it;<br />
};

The last line in the class (in bold) is giving the error:

error C2146: syntax error : missing ';' before identifier 'm_it'<br />

What is it telling me? I have looked it up in help and it seems to have something to do with specialisation but, as I say, I am kinda rusty on C++. Any help would be appreciated.

Thanks

Have you got an #include <vector> at the top of the .h file?

Yes, sorry I forgot to include it in my post.

Microsoft have tightened up on C++ compatability in VS.NET so I think it is something to do with that, in particular specialisation in templates. I wrote this stuff a few years ago (it's a programming language compiler/interpreter) and haven't been keeping up to date so if anybody can point me in the right direction as to why this is happening it will be appreciated.

Along the lines of the other post:

Have you tried replacing your vectors with std::vector? Or are you using namespace std; ?

I have using namespace std;

It compiles fine in VC6 - the issue is to do with template specialisation although I am not using it.

Change the line to

mutable typename vector<T*>::const_iterator m_it;

IIRC, this also affected the WTL 7.0 source, specifically the printing stuff, so Nenad had to change the code in exactly the same way. Nice to know that MS get caught out just like us mortals.... Wink | ;)

Simple Input Box

I'm creating a Time Series Viewer, an I'd like to let the user chose the path he wants (where he has his data).

The problem is I'm not used to MFC, and I'd like to know if there is a way to avoid creating a complicated dialog box.

If I am to do it, how do I include it to my other project, that's to say: how do I tell my main project to call this dialog box when I want it to do so, and how do I get the input in memory to use it?

Thanks

You can use CFileDialog()

WM_MENUDRAG Problem.

I have a small problem...
...and suggesting pills off the internet will earn a slapping!

I can setup a draggable menu, and respond to the WM_MENUDRAG message just fine.
I can even do a DoDragDrop and drag menu items to (e.g.) a toolbar.

But the menu is still there!

What I want to do is to dismiss the menu as soon as the dragging operation
starts (which I should be able to do responding to the WM_MENUDRAG message)
so I can drag to a toolbar covered up by the menu.

I know this is a pedantic niggle, but its been bugging me for ages!

If this is too vague, I'll upload a zipped mini-project and post a URL in
the morning. There's a bit too much code involved to just post here...

Any hints / pointers / examples appreciated,

Iain.

I helped with a similar problem on CG a while back. You can do it like this:

Use SetFocus() on a different control
Use SendInput() and set the dwFlags input to MOUSEEVENTF_LEFTDOWN
Use PostMessage(WM_LBUTTONDOWN, 0, 0)
Use WM_CANCELMODE

Thanks for your help Roger. I'm dealing with the MainFrame menu rather than a TrackMenuPopup one,
but that shouldn't make any great difference. I'll have a play and see what's going on.

So Brussels got the final vote then? I will have to visit the article on it.

I hope to go. I just mislaid (or lost Eek! | :eek:

Looking at the sample, a mouse hook, and ::EndMenu / the cancel menu stuff you quote should
solve my problem nicely. And I'd no longer need a drag / drop menu either!

I knew there had to be an elegant solution out there. When I started to (metaphorically)
bang my head against a brick wall I knew I was using the wrong approach...

Thanks again,

Iain.
