Did you set the SS_NOTIFY style when creating these dynamic controls?

SS_NOTIFY? What's that? I can't find that style in MSDN.

What I've got is the MFC wrapper class for a home grown control. I am creating it like this, in a member function of my CFormView derived class:

CHEditDouble* CGraphView::CreateHEdit(const RECT& rc, const UINT& nID)
{
DWORD dwStyle = WS_VISIBLE|WS_CHILDWINDOW|WS_CLIPCHILDREN|WS_TABSTOP|ES_LEFT|ES_AUTOHSCROLL;
DWORD dwExStyle = WS_EX_LEFT|WS_EX_LTRREADING|WS_EX_RIGHTSCROLLBAR|WS_EX_NOPARENTNOTIFY|WS_EX_CLIENTEDGE;

CHEditDouble* pHEditDouble = new CHEditDouble();
ASSERT(pHEditDouble != NULL);
(void)pHEditDouble->Create("Edit", dwStyle, rc, this, nID);

return pHEditDouble;
}

I'm not sure how to see what the system does with this same control when it creates them from a dialog ersource, something must be different.

The SS_NOTIFY style is not welll documented in MSDN at all. If you do a search and not use the index it should turn up some references.

I use the TT_NEEDTEXT on formviews/floating windows. In the floating ones I create the controls like this:

m_LeakSensors[0].Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_LLEAK_SENSOR1) ;

This makes the tooltip work for that control as long as I map the correct control ID in the onTTNeedText function.

Well, that doesn't seem to make any difference. I tried adding the style, and nothing happened. There must be something else I'm not doing right.

This is a complete guess, but do you call EnableToolTips() before or after creating the dynamic controls?

Well, they are created after the EnableToolTips call. It's a good guess, though.

Add a icon to the status bar of a SDI app.

It looks like it has nothing to do with the way I am creating the controls after all. I tried doing the exact same thing in another project, a simple dialog app, with the same dynamically created control, and it works fine.

I am putting the created controls inside a frame. I think this is messing things up. If I move the frame so it's around some of the controls and not others, then the ones out of the frame get the TTN's, and the ones in it don't.

But I don't want to get rid of the frames, cuz the make the dialog look pertty. Now what? DOes this mean the frame is on top of the controls? Both the frmae and the controls are direct children of the form.

Now I'm confused . . .

ShellExecuteEx()

How can I start application, which name is starting from "home" using ShellExecuteEx()?

If I try to run "homesite5" it brings me an IE window with "homesite5" as an url. It does the same for all names, starting from "home". It isn't depends of such file existance and availability via %PATH%.

And as I found, "Start"->"Run..." acts the same way. Just type "home<something>" there...

p.s. I'm using win2k sp2. win98 seems to have the same bug (or feature?)

With the best regards, Vitaly.

i had never noticed this before.. it seems your best bet is to put it in quotes with an absolute path.. like "c:\homesite5.exe"

still a newb.. cut me some slack :P

quotes will not help...
absolute path will, but i don't know it. the reason I'm using ShellExecuteEx() is cause I need to start different apps knows only their names not paths. winword, notepad etc...

With the best regards, Vitaly.

Anyone know of any articles on "How to" add a icon to your status bar?

Do I have to custom draw the status bar to acomplish this?

Preferred Audio Devices

Is there a way to change the default (preferred)audio devices on Windows NT/2000/XP from an application?

In other words, how can I accomplish the same thing from my application as when I change the Control Panel -> Sounds and Multimedia -> Audio -> Preferred Playback/Record Device settings?

Animation control

I'm having a problem with my animation control. I'm loading a 175 Kb AVI file on my WM_INITDIALOG routine, and I immediately start playing it. However, sometimes when I go to run the software, the AVI takes a while to start playing, so nothing shows on the screen for a couple of seconds. Do I need to wait for the load and/or play routines to complete successfuly before continuing? If so, how would I accomplish that...the WaitForSingleObject routine?

Or is there something else that needs to be done, such as placing the first frame image on the dialog for x number of seconds, then showing and starting the video after x amount of time has passed.

How to change the color of my dialogs?

In the new PocketPC 2002 system the background of my dialogs are white and not gray like in the old PocketPC system.

So, how can I change the background color of my dialogs on the PocketPC 2002 system to gray?

I need this, because I use the CCeButtonST v1.2 buttons from Davide Calabro (http://www.codeproject.com/ce/ccebuttonst.asp) and they look not very good on a white background!

(I am working with embedded Visual C++ 3.0 + PocketPC 2002 + MFC)

I am looking for the APIs which can show all shared files of a computer in a LAN. And how can I get all the computers' names connected to LAN. ( like LANster- a software for searching in LAN).

If anyone knows, please tell me. Smile | :)

I have tried the function : NetShareEnum, but it only showed all the directories that a computer shares. But I am looking for the functions that showed all the shared files.

Couldn't you just list the files in each of those directories then?

That's why I ramble so much. If you're short and quotable, there's a much greater danger of ending up in a sig.
