CNETRESOURCE does have an operator NETRESOURCE... Cry | :((

else it would not compile in VC++ 6.0

Thanks for your time.

The two NETRESOURCE operators need to be removed. They will cause all sorts of problems with standard STLs

NETRESOURCE* operator &()
  {
      return &m_nr;
  }

  operator NETRESOURCE() const
  {
      return m_nr;
  }

Specificall,y the operator & is causing the problems. The & operator is used heavily in standard STL. When STL applies the & operator, it is expecting a reference to the class, not a NETRESOURCE *, thus the problem.

Thanks!

, this removes the error, but now I have to find something to replace the operator, since I get this error...

SelectComputerNetwork.cpp(58) : error C2664: 'CSelectComputerNetwork::EnumServers' : cannot convert parameter 1 from 'CSelectComputerNetwork::CNETRESOURCE *' to 'NETRESOURCE *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Just make a new routine to get that resource. IMHO, I don't understand why NETRESOURCE was made private when the operator & provided unrestricted access to the member. I would just make NETRESOURCE public and be done with it.

I will try to make a new routine to get NETRESOURCE, I also made NETRESOURCE & CNETRESOURCE public, but I get the same error...

Thanks for your time.

Yeah, all you will have to do is change those (*ix) to something like (*ix) .m_nr or (*ix) .GetNetResource ().

Keeping proportion of screen

Can you give any suggestions on how to keep the proportion of the screen the same irrespective of the screen resolution. i.e. Visual Studio workspace appears the same whether you are using 800x640 or 1280x1024.

I am using both dialogs and document views in my program and want them to look the same amongst different users.

Many Thanks

James P

James,

I don't know what you mean by "keep the proportion of the screen the same irrespective of the screen resolution". And actually, DevStudio does not appear the same when you change resolutions. If you have it at 800x600, things like fonts, buttons, menus, dialog boxes, etc. look larger than when you switch over the 1024x768. This is not a bad thing - the higher the resolution, the smaller everything looks but the more real estate you have. That's normal behavior.

What I usually do is make my larger dialog boxes fit perfectly inside the smallest allowable resolution (ie., 800x600). This makes them look fine at the higher resolutions.

Regards,
Alvaro

Bookmarks question

Today I went to go add a bookmark to one of my files and I was shocked to see tons of bookmarks that I did not create. They pointed to source files in directories that I don't even have. I download a lot of free source code from this site and others. When you open a project that someone else created does it add their bookmarks to yours?

Modal, Modeless, Message Madness

C^hris L^osinger10-Jan-02 7:17

I have a dialog application, call it dialog "A". It can launch a modal dialog, dialog "B". The modal dialog can launch a modeless dialog "C" that is owned by the main application dialog (A).

Because C is modeless and owned by A, You can close dialog B and still have dialog C available. (and you can then re-open B, etc).

I want to be able to send a WM_COMMAND message from the modeless dialog C to the main dialog, A. I have a pointer to A, so calling PostMessage to post the message is no problem. The problem is this: when dialog B is up (which is modal, owned by A), the message from C doesn't get to A, because B, being modal, is eating all the messages. Frown | :(

What should happen is this: A, B and C are all up. C Posts a message that causes B to close and A to do something. How can I do this??

You may need to do thi with 2 messages - a WM_CLOSE to close B and then the message to A.

Alternatively, seeing you know this is a 'special' message you could filter it in the PreTranslateMessage function of the dialog(s). If the message always goes directly to B, the filter could pass it on to A and get B to suicide.

Happy programming!!

I would have dlg B post (relay) the message to dlg A before closing. Of course, you'd have to have the CWnd of dlg A in order to do so...

A knows about B, but does it know about C, or does only B know about C?

You could create a CTypedPtrArray of CWnd and store all of the dialogs' CWnd*'s in it, and either make it a global array or pass it in the constructors from one dlg to the next, and have each dialog add it's own CWnd* to it as it goes. Then, you could post the message to the desired CWnd*'s.

A owns both B and C. C knows about A and B knows about A (A is their parent). C doesn't know anything about B, though i guess i could hack up something that would make it available.

what a mess Smile | :)

If A knows about both B and C, and if you want something to happen in B if C closes, just Have C post a message to A to indicate that C is closing, andf have A post a message to B that tells B that C has closed and B can react accordingly...

Sounds like you already have everything you need.

Loose cable? Damaged card? It does not seem like a software problem to me. Maybe switching to another testing scenario (different cable/machine/card) could shed some light.

II. Get a process's CPU usage at a specific given time (Must).
III. Can enumerate all running processes (Optional...).

2. I want to download CPop3Connection class that I found at this site
using the search engine. Unfotunately I can't find it.
I'll be very glad if someone will leave a link to it...

Problems with Ms Word and Automation

Hi,

I´m using Automation to have in one splitter window a Word window and in the right pane some buttons to add graphics tables...

The problem comes on XP, when I close that window, I get some strange error when it´s close ( OnSize is called after the window is destroyed), here is the code i call

void CReportFrame::OnClose() 
{
    TRY {
	// must destroy report bar manually
	CWnd* wnd = m_wndSplitter.GetPane(0, 0);
	wnd->DestroyWindow();
	delete wnd;

	// handle inplace Word view
	CReportDoc* pDoc = GetReportDoc();
	COleClientItem* pItem = pDoc->GetPrimarySelectedItem(GetReportWordView());
	if (pItem != NULL) {
	    pItem->Delete();
	    //delete pItem;
	}

	CFrameWnd::OnClose();

	delete pItem;
    } CATCH(CException, e) {
	AfxMessageBox("CReportFrame::OnClose : exception caught.");
	ASSERT(false);
	e;
    } END_CATCH;
}

Thanks in advance, Bye !

Maybe you should use: m_wndSplitter.DeleteView(0, 0);
instead of:

// must destroy report bar manually
CWnd* wnd = m_wndSplitter.GetPane(0, 0);
wnd->DestroyWindow();
delete wnd;

I'm trying to call a Property Sheet from an explicitly linked

The DoModal function is called but no Window appears, I get the trace message "CPropertySheet Returned Error code 0"?? But that means Success!

It Works for Dialogs etc..

Has anybody else had the same problem?
