Hi guys
Somebody has an example about to reduce the minimum size of a ComboBox
When I add a Combo box,there is a minimum size and I'd like to have one smaller (I talk about height) than this.
Do you know a derived class where I could see how to do this?
Best Regards
Doc

You can adjust the height within the resource editor. If you click on the down arrow portion it outlines the minimum size.

You might want to try SetItemHeight for the combo.

i want to draw into a windows menu but i
can't find a way to get a device context
for it. more specificially, i want to
make a rectangular menu of icons. windows
doesn't seem to support rectangular menus,
so instead i am making a menu with 1 owner
drawn item. i draw the menu when i get the
WM_DRAWITEM message. i can select the
correct option because i can call
GetCursor() when processing WM_MENUSELECT.
what i can't do is update the highlighting
while the mouse moves. i can process
WM_EVENTIDLE messages, but when handling
this message i have no way of drawing into
the menu. WM_DRAWITEM provides a DC, so I
know one exists in the system. Is there
any way to copy this DC and use it later,
or get the DC? Are menus implemented as
windows? Because if so i could maybe
get the hWnd for the menu or something.
Thanks, Phil.

I am studying the communication of MS Media Player while it plays a http file. I find a interesting thing.
I wrote a small program to accept requests from the media player. For most video files like mpeg, I found that it sends http get request to download a the video file. But, the I tried to use the media player to play a wmv or asf file, it did not send any request, it however tried to receive the information from the server instead of sending a request. As result, the server program of course can not provide any wmv/asf file for downloading by media player.
I don't understand why media plyer doest not send an http request while downloading wmv or asf files. What possible inside operation does it perform?
Could you give me some tips?
|
|
|
|
|
Does anybody know?
Why does the web client begin to receive information from the server before sending a request? In what case they will do that?

I am currently using the Pdh to enumerate through processes running on the system in order to get the process id of a particular application.
Given that I know its name is there a simpler way to achieve this?
Thanks

Thankyou David
I particularly like the WMI flavour.

Okay, so WMI seems pretty neat, until you figure out what it takes to get it installed if it is not already on a system. Just a word of warning before running off to depend upon it.

Thanks I will bear this in mind

I wrote a resource script with menu resources duplicated on several languages.
MSDN states that I can control loading appropriate version of resource using
SetThreadLocale() call, but this way doesn't work. Operating system always
loads English version of menus in spite of what thread locale I'm using. Can
you tell me what's wrong? I'm working with Windows XP SP1.

What value does it return?

SetThreadLocale() return TRUE. I'm feed in it LCID equal to
MAKELCID(MAKELANGID(LANG_RUSSIAN, SUBLANG_DEFAULT), SORT_DEFAULT),
but it resources loaded in English. Dont know why?

Hi,
I use a thread in my app and in one portion of the code, the thread call another class. This class trie to pop up a window but get's a handle of 0x0000. Look like the Create or CreateIndirect fails.....
<br />
CWaitDlg *w=new CWaitDlg ("","Please Wait");
w->Create (IDD_WAIT); <br />
w->ShowWindow (SW_SHOWNORMAL);<br />
<br />
|
|
|
|

The handle will always be 0 until you actually create the window.
John
|
|
|
|
|
You are right.
The problem starts when I use the Create function.....
|
|
|
|
|
Is the thread that creates this based on a UI type thread or a background worker thread? If you are using MFC (which it appears), this is very important, as you should only create UI elements with a UI thread. See AfxBeginThread() in the Docs for more info.
onwards and upwards...

I agree this is essential with MFC and the GUI.

Hi everybody,
I would like to create a function which could allocate memory for any of pointer of pointer declared.
In my class C, i consider 2 pointers of pointers : **p and **q ( declared as public in class C), i would like to create a function AllocMemPointerOfPointer, which takes 3 input : RowSize, ColSize and Pointer. The function doesn't return value. It just allocate memory for Pointer, which is a pointer on RowSize pointers of any type .
How could i do that without allocate memory to a "copy" of Pointer ?
I hope my question is clear ! if not, feel free to ask me more informations !
Thanks in advance for your answers
Gerald

Maybe you should make your modal dialog window have the desktop as its parent?
Try calling GetDesktopWindow() and use the returned handle for the parent of the modal dialog and see if that helps.

Hi!
I am trying to use the registry with win32 api c++.
But I have difficulties using the RegQueryValue functions.
I found some examples on the net but they all use CString and I cant use it because I dont write in MFC...
Can someone write an example? ( if possible the whole thing how to get a value?)
Thanks in advance!
Well... I am a beginner ...
