Are you trying to develop an RTP player or download and use a third=party one?

Hi everybody,
i perform a PostMessage(WM_NEXTDLGCTL); and the focus is not set on the next
control but is set on the second next control.
Is there a special thing to know?
Big thanks

do you set the "tab stop" property to true for that control.
Note: If the next control is a list control and you are trying to do a TAB for setting the focus on that control that list SHOULD contain atleast one item before it shows that it gained focus
modified:The tab order for your window can be changed by pressing ctrl+d in resource view(ie design time)
Somethings seem HARD to do, until we know how to do them.

Thansk for your answer
The next control is a DatePickerWnd.
All controls have "TabStop" to TRUE.
If i press the TAB-Key on the control, then the focus steps on the (correct) next control.
But via WM_NEXTDLGCTL it steps 2 controls farer.
If i remove the WM_NEXTDLGCTL, the focus stays on the initial control.
And 2 WM_NEXTDLGCTL sets the focus indeed 4 controls farer

Probably that's how you've set up the "Tab Order" in design time?

The Tab-Order is correct at designtime and during the execution of the application.
Pressing the Tab-Key navigates me correctly trough the view ...
thanks for help

Did you read the fine print on the MSDN page[^]? (The parameters - wParam, lParam and the Remarks section)

Yes, but i doesn't work for me 
A PostMessage(WM_KEYDOWN,(WPARAM)VK_TAB); sets the focus to the previous control
but with silly sideeffects (insertion bar is still in the initial textbox and the new taped characters are inserted in the new textbox )
Thanks anyway

You told me that you read the documentation:
If wParam is zero, the next control receives the focus; otherwise, the previous control with the WS_TABSTOP style receives the focus.

That was just for testing (in this case i use a WM_KEYDOWN and not a WM_NEXTDLGCTL )

Try GetNextDlgTabItem(PrevWnd)->SetFocus().
BTW read the docs carefully on WM_NEXTDLGCTL. It has some detail associated with it.

Yes, i already read the MSDN-Documentation.
I don't have a handle to the next control.
I call the WM_NEXTDLGCTL in a universal function, which sets only
the focus on the next control, wherever the control is placed.
In my case:
I hit the F2-Key on a certain textbox. A Dialog opens modal and shows a Grid.
The user selects a line and the Dialog places a string into the textbox (where the user hit's the F2-Key)
Then i post the WM_NEXTDLGCTL Message so that the next textbox is selected.
Thanks

Well for testing purpose, I put this event call in a timer
void OnTimer( UINT Id )
{
PostMessage( WM_NEXTDLGCTL, FALSE, FALSE );
}
Works well for me, focus shifts properly around all controls in the dialog. Then I put it in a button event handler, after this the focus always moved to the Cancel button, guess why? So you need to watch out for such issues.
A wild guess! Are you posting WM_NEXTDLGCTL twice, since it's a post message you wouldn't know, a suggestion would be replace PostMessage with SendMessage(MSDN says don't) for testing purpose to find out where if at all a duplicate one is being posted, since it blocks. Don't forget to revert back to PostMessage.

Hi. I am programming c++ with MFC on VS2005. I was wondering how you can make your application draw outside its own window.
There are softwares out there that allow a user to scribble anything on the computer screen over any applications that are running or the desktop. A couple of them are
ActivePen (http://www.kongda.com/products/activepen/default.asp),
VBDoodle (http://www.hopkinsprogramming.net/software/vbdoodle/gallery/)
Draw-On-Screen (http://downloads.zdnet.com/abstract.aspx?docid=352162)
My question is how would I replicate this behavior? Im new to visual c++, and although i have experimented with making my own version of paint, I was only able to draw inside the screen of my MFC application which was made using Edit view class as base class. Did not see any way to draw just anywhere on the screen outside the window.
It would be great if you could maybe name a few built in classes/methods that can do this, or provide me with a link to a known resource on this topic. Thank you.

If you are using MFC, you can use CWindowDC dc(0); to get a device conext to entire screen. Other wise use GetDC(0) to get the dc to entire screen.
Any drawing to the above dc's will come in screen at the specified locations.
|

|
|

On similar lines as the answer you received above you can get a dc for the desktop window HWND. The desktop window hwnd can be obtained by GetDesktopWindow API
Somethings seem HARD to do, until we know how to do them.

Hi All,
We have quite about 30 clients connecting to about 200 servers on our WAN. Currently we are experiencing extremely slow connection establishment times, in the order of 15-20 seconds. However, a ping from a client to the same server responds in 1-2 seconds.
The client and server applications are based on WSASocket.
I have traced the client and server side applications to death and it seams that the delay is in the receiving of the FD_ACCEPT event. Once the event has been received and the connections established, all seems fine, but it takes an unusually long time for the event to be received (through WSAEnumNetworkEvents).
Are there any reasons for the connection establishment to take SOOOO long, while a ping goes through quite quickly ?
Thanks
OD

Sounds strange, maybe your routers do some traffic shaping or you hit a bottleneck in your network infrastructure. I would try to send more dummy data with the connection handshake (to see if that has a negative or positive impact), plus try another listening port number.
