You need VC 7.x for that class.

Service stops when LOG OFF from the system

hi friends,
i m facing one problem while using services.
the problem is..........

The service behaves well initially when i start manually through service interface(service is not autostart, one has to start manually). As soon as i LOG OFF from the system & again LOG IN to the system i found that service stops however when i check the service interface it shows that service is running and even TASK MANAGER displays the EXE of SERVICE as running status.

i hope u understand my problem.
waiting for reply.

I assume that urs in an ATL Exe Service, so you register it
by servicename /Service
by doing so it wont stop ther service even if you log out.

I'll try it but I didn't use it for a long time. I used the TrackMouseEvent() for an owner drawn caption where I needed to track whether the mouse has left the caption.

Header:

bool m_bMouseTracking

Constructor:

m_bMouseTracking = false;

void OnMouseMove(UINT nFlags, CPoint point):

if( !m_bMouseTracking )
{
    TRACKMOUSEEVENT tme;
    tme.cbSize = sizeof(tme);
    tme.hwndTrack = m_hWnd;
    tme.dwFlags = TME_LEAVE | TME_HOVER;
    tme.dwHoverTime = 1;
    m_bMouseTracking = _TrackMouseEvent(&tme);
}

void OnMouseLeave(WPARAM wparam, LPARAM lparam):

// Here I did my repainting stuff
...
m_bMouseTracking = false;

But I think you can use TrackMouseEvent() only with Windows98 and newer. If you want to be compatible to older OS's too, you should look for SetCapture() and ReleaseCapture(). Then you can check on which OS your app is running and switch to the appropriate tracking mechanism... Wink | ;)

boost makes min/max ambiguous

Hi,

when I include the boost library into my project, I get min and max as "ambiguous symbols".

it is enough to include boost/config.hpp

Now my project is fairly big (and I already removed two "using namespace std" instances in a header file), yet the error persists, and I have no idea how to track it down.

Any ideas?

Flirt harder, I'm a coder.

Have you tried defining the macro NOMINMAX in your project settings? This effectively removes Windows min and max macros.

Start by reading about Word's automation Object model.
You can, I recall, access the document's collection of tables.
Having done this, you should be able to refer to properties of the table to extract text from it.

If you know VB it's helpful

Hi,

I have an output file (text file). In the text file there are a few locations of other text files, along with the name and path of each file.

it seems like if the location is anywhere other than the desktop the file can not be found.

How can I read the location of a file from another text file and open it?

Thank

Enlarging dialog window

How can you handle the case where you want to put a Max limit on the size that you can make a MFC dialog based application window.

I store the main dialog windows size in the InitDialog routine, but how do you limit the resizing?

I placed code in the OnSize, but it did not work.

How to make a PropertySheet window always display as the top-most one?

bin89222-Feb-04 6:01

2-Feb-04 6:01

I am working on a project of BHO and I need to make a PropertySheet dialog box pop up when I click on an item in the context menu. The property sheet is from the BHO. The problem is sometimes the PropertySheet is displayed under the current IE window and the user cannot see it. I know what caused the problem. It is because there is one BHO for each IE window. But when a property sheet is called, the program just use PostMessage to send out a message, and the first BHO that gets it will display the property sheet. That is why sometimes the property sheet cannot be seen. How do I solve this problem?
I tried to use SetWindowPos(NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE) in the property’s initialization function. But it doesn’t work. I also tried to add SetForegroundWindow(); before that. There is still something wrong with it. First, it will make the IE window that the BHO hooked to become the window on focus and make the current IE window hide; Second, it only works on the IE windows from the same thread(The new window is generated from current old window by clicking on File->new->Window). It doesn’t work when the IE windows are on different thread, for exampe, generated by clicking on the blue “e”.

Please help. Thanks a lot in advance

I am not familiar with BHO but did you try wndTop as the first parameter to SetWindowPos() instead of NULL?

Multicasting and UDP

Can somebody please enlighten me on the topic of Multicasting and UDP? Confused | :confused:

I am trying to build a simple chat program, but the problem is that I will need to load one socket per client, so there will be a very big number of connections and I don't want that. The fact is that I heared that Multicasting can help a lot. How can I find out IPs of computer on a LAN and send messages all around?

Thank you lot in advance ! Smile | :)

Alright. I'm stepping through my code in Visual Studio.NET and I notice in the "Autos" window variable values turn red. I assume this happens to show that a variable value is being modified or was just modified. But I'm not sure. Could somebody explain?

Thanks in advance.
