Check the following files "test.h" and "test.cpp".
When using the following code, Class View does not identify the constructor correctly,
and displays it as Global() and not as test().
If Global is defined in the same file ( test.cpp ), the bug does not occur.
Does anybody know of a solution to this bug?

test.h
-----
#define Global __declspec(dllexport )

test.cpp
------
#include "test.h"
class test {
Global test();
};

I built a WebService in C# and consumed it in VC. All works on the machine with VS.Net, but fails on the client machine after the install. I have included both msvcr70.dll and mfc70.dll with the install. Any suggestions as to what I'm missing?

How can I do this?

I have an SDI application. When WM_CLOSE message is received by CMainFrame, I want to check a flag bSthInProcess. I want the application to exit only when this flag is clear. So I coded

LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
    if ( message == WM_CLOSE )
    {
        CMyView *pView = (CMyView *)(GetActiveView());
        if (pView->bSthInProcess)
          MessageBox("wait while exiting.. "); //<== problem here
        while ( pView->bSthInProcess )
          Sleep(2);
    }
    
    return CFrameWnd::WindowProc(message, wParam, lParam);
}

the problem is, if I use MessageBox(), use have to click on the OK button. I want a message which will display the message, and close itself when the application closes.
How could I code it? Confused | :confused:

Thank you very much! Rose | [Rose]

You may want to use a modeless, custom dialog box.

Thank you, this works.

is there any easier way to do it? I mean, is there any API funciton like MessageBox()? Confused | :confused:

You will have to do a custom modeless dialog box because MessageBox is a modal dialog box function. There are no other quick APIs to creating a message box.

Do this. Create a thread. Show the messagebox from that thread. Just after you start this thread, Sleep() for a while, then continue. Thus when the main thread exits the second thread is closed.

Hi Nish,
I believe your method works. But it is not any easier to implement in terms of lines of code economy. Hmm, on second thought, I don't need to create a dialog class for this. That's the advantage. Thank you!

Performing registration -- What does it performs ?

Hi,

When I compile and ActiveX object using ATL, I can see the "Performing Registration" friendly message in the Build View.

My question is.. what operations does it performs ? Only RegSvr32 ? or RegTLib or... ?

Thanks, Bye !

Hola Braulio!
Go to Project -> Settings -> Custom build tag. The commands executed after building the object are:

regsvr32 /s /c "$(TargetPath)"
echo regsvr32 exec. time > "$(OutDir)\regsvr32.trg"

which executes rgsvr32.exe and times the operation. It could be that the commands are different for the particular project configuration you selected, but now you know where to look Smile | :)

Hola Joaquin !

I looked at that, I was very confused because, I can make work my ActiveX COM Object if I compile the source code in the same machine ( if not then it will fail to pass the metafile Frown | :-(

for the thing of handling my activeX inside a word automated instance in my MFC app), I thought maybe I forget to register the TLB or ... no idea Cry | :((

I don´t know what to do..., The only ideas that I have is to Marshal the interface ( now what I make is to have an Stream in HGlobal that should be enough), or try to get the metafile buffer and paste it in an safe array or as CData in an XML Dom tree).

What do you think ?

Braulio

Ummm... If you go to Project -> Settings, select your .idl and then the Custom Build tag, you can see the command midl is invoked.

midl /Oicf /h "test.h" /iid "test_i.c" "test.idl"

I hope this makes some sense to you (I'm no expert in ATL COM stuff).

NT\2K users?

Many of us work for Corporations that have central servers. This NT\2K servers each have a list of available users that are allowed to connect to the server. Is there anyway to Query the server and get the entire list of users? Also, Is there any way to query each network computer and see what user is logged on?

Nothing is impossible, It's merely a question of figuring out HOW?

question on SHFILEOPSTRUCT

i have something wrong but not sure what to look for.
the directory that i am passing is vaild (i can use _rmdir() and it works using the same variable.
but my problem is that i do not know how may files or sub-diretories may be in the the folder that i wish to delete. From what i understand this function will delete folders that have contents. i have been trying to delete for now an empty folder dirname = c:\\junk
when i run SHFileOperation() i get:
Cannot Delete File: File System Error(1026)
if i check the attributes on the directory there is nothing checked.

thank you for any help

SHFILEOPSTRUCT shf;
memset(&shf,0,sizeof(shf));

shf.hwnd = mywindow::GetSafeHwnd();
shf.wFunc = FO_DELETE;
shf.pFrom = dirname;///////////////this is a valid directory
shf.fFlags = FOF_SIMPLEPROGRESS | FOF_NOCONFIRMATION ;

int shfret = SHFileOperation(&shf);

Re: question on SHFILEOPSTRUCT

Joaquín M López Muñoz25-Mar-02 7:32

The pFrom member is a "multistring", i.e a string composed of many substrings terminated by '\0's. In your particular case, there's only one substring terminated by '\0' plus the standard '\0' regular C strings are equipped with. So, try with "c:\\junk\0" and tell us if that worked.

Window's visual behavior overriding

Can anyone help me?
If I override window sizing (lock WM_NCLBUTTONDOWN / HTLEFT..HTBOTTOMRIGHT and so on until WM_LBUTTONUP), do i have to dispatch WM_ENTERSIZEMOVEs and WM_EXITSIZEMOVEs? Where do they appear - in DefWndProc main message loop or sent by WM_NCHITTEST / sizing handler?

These messages are sent in the DefProc handler for WM_SYSCOMMAND with the SC_SIZE, or SC_MOVE flag set in this message.

I am not quite sure what your question is, or what you are trying to accomplish, however, here is the flow of message generation. If the message is indented, that means that it is generated in the DefProc handler for the message before it.

I hope this helps you.

There is an article about manipulating the start-up menu. I dunno if you can add anything to the shutdown dialog, I don't see why not...?

However you could I imagine display your options prior to the shutdown dialog using this authors techniques.

CControlBar show...?

alex.barylski

24-Mar-02 23:58

I asked this questio earlier and didn't get an answer...perhaps I was to vague i'll try and be more specific.

I have derived a class from CControlBar(which is derived from CWnd so nothing should change much should it...?)
and naturally overriden the Create().

My window(derived CControlBar) is created but also creates it seems 2-3 others???

I used spy to verify the window was created and it's show a few more childs then I thought should be there...?

ANyways...using Spy I determined that the reason my CControlBar isn't showing is because it has a negative height.

0,0,320,-2...???

What do I have to do to show the Window...? i've done this a hundred times with generic CWnd, but the same doesn't apply to the CControlBar obviously.

When createing the CControlBar I specify a command ID within range:

AFX_IDW_CONTROLBAR_FIRST+32

What else am I missing...?

Thanx! Smile | :)
