Dear Roger, Dave, thank you again for your answers.
since English is not my mother tongue (hint: i fluently read the original scripture of Ecclesiastes, the resource of the poem Roger quotes ), the question i posed may have been somewhat unclear.
i want to embed a combobox inside a list control subitem. now, by changing the combo font size i can control the combo (==edit+arrow == -1 item) size (SetItemHeight(-1, x) fails here), and visibly make it smaller than system default (without resorting to Owner-Drawn combo). alas, i wish to programatically quantify the combo frame VISIBLE size, to some actual pixel measure (i do not wish to use the resource editor). i cannot get it with GetClient\WindowRect() because of unknown reasons (which have nothing to do with drop down list size).
i hope i could profit from your experience.
Thank you all![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) , yonatan

Use CComboBox::GetItemHeight()/CComboBox::SetItemHeight() with nIndex set to -1 to get/set the height of the edit/static control portion of the combobox

Add your own handlers for cut/copy/paste
ON_COMMAND(ID_EDIT_COPY, OnEditCopy)
void CXView::OnEditCopy()
{
CWnd* pWnd = GetFocus();
if ( pWnd != NULL )
pWnd -> SendMessage(WM_COPY);
}

How to add an item to desktop's context menu or is there an article to read about this?
|
|
|
|
|
For CodeProject articles dealing with programming the Shell and with the Shell API, see to General -> Shell Programming.
The desktop is a part of the Shell. Just like the Start Menu, Quick launch, Task Bar and Tray Area are parts of the Shell.
Here's a direct link to the Shell area: http://www.codeproject.com/shell/[^]
I recommend the article by Michael Dunn 'The Complete Idiot's Guide to Writing Shell Extensions', parts 1 to 8. Happy reading

I have dialog based application.
Main dialog contains it's own controls, like button, and one TabCtrl.
Tab control contains couple of child dialog windows, their visibility is determined by selected tab in tab control.
I need to make this resizable, but it's flickering to much, especially tab control and child winwow's controls.
I tried to disable OnEraseBkgnd on both main window and child windows, but with no effect.
How to do this ? 
Thanks

i am not sure it will work but,
in the resource of the dilaog choose properties of the dialog, and in the style tab check the 'clip siblings' and 'clip children'
this should do the trick.....

I am trying to change an environment variable from a code.
I have tried the each one of the following:
1. sprintf(szCatiaBase, "CATIA_BASE=%s" , (LPCTSTR)strCatiaBase);
nRet = _putenv(szCatiaBase);
2. sprintf(szSysCall, "set CATIA_BASE=%s", (LPCTSTR)strCatiaBase);
nRet = system(szSysCall);
3. CRegKey rkRegistry;
CString strValueName("CATIA_BASE");
rkRegistry.Open(HKEY_CURRENT_USER, "Environment");
sprintf(szValue, "%s", (LPCTSTR)strCatiaBase);
LONG lRet = rkRegistry.SetValue(HKEY_CURRENT_USER, "Environment", szValue, (LPCTSTR)strValueName);
rkRegistry.Close();
BUT....
None of the above actually changed the environment variable - when I opened the cmd console and tried to see the envonment variable's value thruogh:
> set CATIA_BASE
I got the old value - meaning - the environment has not changed!!!!
Does anybody know how this should be done so the the environment will realy change?????
Thnx

On my hard disk I have 4 partitions. The one partition I formatted in the ext2 format so I could run Linux from it. However I would like to now change the format of the partition back to vfat (so it can be seen by Windows). Does anybody know how I can do this? OR is there aprogram available to do this? I don't want to reformat my whole harddisk.

What flavour of window are you running?
To keep linux files - use partition magic. If you don't care for those, delete and re-add partition.

I am running Windows 98  .
I don't have partition magic. The problem is that I can't even access the partition with DOS.

I need a program (create it in VC++ console app) that does Disable. or Enable Network Connections like when you do this:
1. Win XP Prof. - Open Network Connections.
2. Right-click the LAN or High Speed Internet connection that you want to disable.
3. Click Disable. or Enable
I was searching in "Platform SDK: IP Helper" IpReleaseAddress
GetAdaptersInfo ...
I did find only a funtion doing the same thing like (win32 command)
ipconfig /release myLocalAreaConnection
BUT this does not help me because we do not have DHCP enabled.
Many thanks for any hints

I inadvertedly deleted the .scf entery in my Register, so now I can't click on the "Show Desktop" Button. Does anybody know the entry for this in the register? I think it might be something like "%1"%* but I can't get it to accept it.
I am the handsome one in the crowd.

Put this in notepad save as .scf
[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop

The .scf file contains the lines when I open it in Notepad. What I am missing is the entry in the Register. That is when one runs regedit then there should be a key with something like scffile and subkeys like shell, command, open. That entry under open is missing and what I need to place in the register.

Hi there
I have been trying to use CToolTipCtrl with splitter views (CSplitterView).
In my SDI project, I have 2 views created with CSplitterView which contain
bitmaps. I want tooltips to appear when the mouse moves over a bitmap. I
have been successful in implementing this, but... the problem occurs when I
do the following:
- I click on view A
- I move the mouse into view B, over a bitmap. The tooltip appears but with
the text "Last Record". What happens is that window B is not receiving
TTN_NEEDTEXT message. I need to click on window B to have the correct text
displayed.
I would need help to implement one of the following:
1. how do I route the TTN_NEEDTEXT message to all my views.
or
2. how do I disable the tooltip in a view as long as this view is not
receiving TTN_NEEDTEXT message.
or
3. any other brillant idea.
Thanks a lot!
Laurent

So here is my solution:
I have implemented a method to handle TTN_NEEDTEXT for the mainframe. The method sends the
message to the window at the location of the mouse pointer:
BOOL CMainFrame::OnToolTipNeedText( UINT, NMHDR*, LRESULT* )
{
const MSG* pstpMsg = NULL;
CPoint clCursorPos;
pstpMsg = GetCurrentMessage();
::GetCursorPos( &clCursorPos );
::SendMessage( WindowFromPoint( clCursorPos )->GetSafeHwnd(), pstpMsg->message, pstpMsg->wParam, pstpMsg->lParam );
return TRUE;
}
Anybody sees any problems with this implementation?
Laurent

There seems to be no apparent problem with the implementation you specified.
The basic handling of the splitter window, I think, when receiving a tool tip request, is to pass the request to the view which currently has focus. What you are doing here is trapping the tool tip request message and passing a notification to the window under the mouse instead, which is the correct way. I am unsure if this is correct, you could check it with Spy if you need to.
I believe that if you didn't implement this, the tooltip showed by the view would be the one bound to the view currently having focus. So, if you clicked on view A and moved your mouse over to B, the tool tip displayed would be the one bound to view A, and vice versa. However, as I didn't see the code you used, I cannot be sure, as I haven't tested it myself.

Hi!
I am doing measurments on IP-TV. My program is joining a multicast group and then I recieve video packets from the group.
I will study the packets I recieve, but I do not know how to convert from mpeg-2 to ASCII in c++ and vice versa.
If there is someone out there that knows, I am thankful for your help,
|

I don´t know exactly what do you mean when you say 'convert from mpeg-2 to ASCII in c++'.
I have developed (for my company) a mpeg transmission system based on RTP protocol. I listen to a multicast port and i receive the data in a buffer i provide. I mean, I create a buffer like this...
BYTE *pBuffer = new BYTE[BUFFER_SIZE]; // buffer big enougth
then the socket functions fill the buffer and I use it like
SRtpHdr *pHdr = (SRtpHdr *)pBuffer;
Once I proccess the headers I reach the raw mpeg data to proccess itself (i mean, save to a file, display using DirectShow...)
