My problem is this:
I use SetSel() and SendMessage(EM_SETCHARFORMAT, ...) to highlight stuff in the control, and it works fine when using SetWindowText() to set the contents of the control. However, when I use streaming for setting the contents, and if the selection to highlight starts at the first character position (CHARRANGE.cpMin = 0), the highlighting is applied to the entire contents of the control. Moreover, the formatting remains when I fill the control with new text, even if I don't highlight anything in the new text.
Reproducable with:
<br />
int nTransfer;<br />
<br />
nTransfer = _tcslen(m_pchStreamBuf);<br />
if(nTransfer > cb)<br />
nTransfer = cb;<br />
memmove(pbBuff, m_pchStreamBuf, nTransfer);<br />
*pcb = nTransfer;<br />
m_pchStreamBuf += nTransfer;<br />
return 0;<br />
<br />
CHARFORMAT2 cf;<br />
memset(&cf, 0, sizeof(cf));<br />
cf.cbSize = sizeof(cf);<br />
cf.dwMask = CFM_COLOR | CFM_BACKCOLOR;<br />
cf.crTextColor = RGB(0x00, 0, 0);<br />
cf.crBackColor = RGB(0x00, 0xff, 0xff);<br />
m_ctrl.SetSel(0, 3);<br />
m_ctrl.SendMessage(EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf);<br />
Anyone?

Hi All,
I am writing a Win32 application to retrieve the information of all process running on the user’s system. To do the same following steps are used:-
Create the process handle Using Win32 API OpenProcess(,,), on passing process id as a parameter
Handle returned by OpenProcess(,,) is further used to retrieve the other information of the process like process name, associated modules etc.
OpenProcess API fails to create the handle for process id 0(system idle process) and 4 (system). API always returns NULL for process id 0 and 4 and hence I am not able to retrieve the associated information.
dwPID = 0 ;//or 4
HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, false, dwPID ) ;
if ( NULL != hProcess )
{
if ( EnumProcessModules(hProcess, &hModule, sizeof(hModule), &dwTotalModulesSize) )
}
else
{
cout<< “Unable to open handle “<<endl ;
}
Please let me know if there any way to get desired information for pid 0 and 4.
Thanks in advance

actually they are system process, they keep track of system idle time, so mightbe that will reason you mightn't be getting the handle to the process!

So why aren't you calling GetLastError() to find out why?

What on earth are you waffling on about? The only security hole is access rights on the remote machine, which by default are extremely limited.

If you think that accessing your CEOs (or any coworker for that matter) C: (D:, E:, F:...-Drive is not a security-hole, I think no one can help you.

have you ever work on network!? \\SYSTEM_NAME\\c$ is still available except now you have to provide username and password.

Oh - thats new, then. The hole is closed here for years, now.
In XP you still could access anything not hidden well enough.
E.G. Your bosses USB-Stick (FAT-Formated as it is).

OK, again slowly:
Until recently, even in XP (I think), you could scan all mounted drives on all computers in the local windows-network (that is anything up until the next network router).
Anything between you and full access was the Windows file security. Non-existant e.g. on USB-Sticks.
That IS a security hole. Regardless what Microsoft-cultists say.
This could have been switched off in the registry. See here[^].
Our network policy enforces this.
Now you tell me, that this no longer the case. Fine.
It should have been never. And the ones responsible for that need to be disgraced until their fourth decendant.

As an owner of a small local area network with only 3 PC's in it all on my desktop I am glad this feature exists it makes it so much easier.

Easier than just creating a real share where you need it?

well actually no, because I know how to use Net Share from the commandline, but yes if all I had was the poxy windows folder share prpoerty sheet it is much easier because the property sheet sharing page wants to reset all permissions on every thing below the share point which is totally unneccessary in a desktop lan environment.

Hello,
I have a tab control, contents of which are displayed by a CDialog. This dialog contains different controls on it. I am having following issues :-
1) After I run my app, if I put another window on top of it (say calc.exe) and switch back to my app, I see the area convered by calc.exe is erased!
2) I have a menu which pops up if I do a right control on the header of my Clistctrl .. after the menu goes away, the area covered by the menu is erased and comes back only when I move my mouse over the area...
3) If I hit enter the contents on the tab control (which are displayed by CDialog) go away completely!
Thank you in advance for your help...

I guess it is because of z-order problem. What is the parent child relation of tab and the dialog having the controls?

Override OnOK() and OnCancel() in the dialog having the controls. Like OnOK() { } and OnCancel() { } in the class declaration. Rebuild the project to avoid compilation issues.

Thanks NS...
>> I guess it is because of z-order problem. What is the parent child relation of tab and the dialog having the controls?
How do I find that out?
Also, another problem I forgot to mention was .. if I hold on move my app window, the controls start disappearing ...
|

See, if a button is placed in a dialog, then the dialog becomes the parent of the button and the button is a child of the dialog.
Similarly, if the tab and the controls' dialog are the childs of the same parent, then there can be painting issues like you specified.

class __declspec(novtable) CIOMessageMap<br />
{<br />
public:<br />
virtual bool ProcessIOMessage(IOType clientIO, ClientContext* pContext, DWORD dwSize) = 0;<br />
};<br />
<br />

<br />
#define END_IO_MSG_MAP() \<br />
return bRet; \<br />
}<br />
Why class CIOMessageMap should be declared by declspec(novtable)?
The macros implements the member function of CIOMessageMap --ProcessIOMessage();But in other places of project,there no any inheritances of CIOMessageMap.
Who can tell me the advantages about this coding style?
There are will best in detail.;)

ProcessIOMessage() is defined as virtual, so the compiler wants to add a vtable for the class. But, because it's an abstract class (due to the = 0) it cannot be instantiated and doesn't need the overhead of the vtable. __declspec(novtable) instructs the compiler to not generate a vtable.
A more detailed explanation can be found here[^].

Hi all,
I was able to set particular cell's content by CRange::put_Item() from MFC typelib class, but how can I set cell's background color and put comment into it? I've googled it but got no result so far.
Thanks,
|
|
|
|
|
To set the background color, look for an Interior property of the Range object, Interior has a Color property that specifies the color of the background, the Range can span cells.
To add a comment, use the AddComment method of the Range object.
|
|
|
|
|
Thanks, Roger!
But how can I reference the color property?
range.get_Interior();
and when "range.AddComment(COleVariant("1234"));" was reached an exception happened.
