When trying to use my ActiveX control in Visual C++, I noticed that when inserting the control in the dialog the control will not be created which causes the m_hWnd to be NULL which causes problems in my control behavior at design time. What shall I do to overcome this problem? Any ideas?

I´m having problems getting the my process handle, using GetCurrentProcess() I always
get 0xfffffff... back. I need to get my own process handle to pass on to a watchdog process to monitor, has anyone any idea how to get to grips with this problem ?
ps, I´m using ATL/WTL and API NO MFC

The return value is a pseudo handle , to get the real handle use GetCurrentProcess() with DuplicateHandle() or call to OpenProcess()

Thanks, I used the following code
HANDLE hHandle;
DuplicateHandle(GetCurrentProcess(), GetCurrentProcess(), GetCurrentProcess(), &hHandle, PROCESS_ALL_ACCESS | STANDARD_RIGHTS_REQUIRED |THREAD_ALL_ACCESS, FALSE,NULL);
CloseHandle(hHandle);
That worked...

The 0xff thing is correct as in the doc however u may want to use the PID instead i.e. GetCurrentProcessId()
Until the process terminates, the process identifier uniquely identifies the process throughout the system
|
|
|
|
|
That´s true, but as far as I Know (read) you can not terminate or kill a process with the PricossID, just with the Process handle.
But any way, I ´ve solved that problem, know I have to change the Token on NT/XP/2000 system to Terminate/Kill the process, and Shutdown or reboot, and the MSDN is not very helpfull at all

I have a program (like a virtual keypad) which I wpould like to inject typed things into another process. What I have works if the program that gets it is the main window (like notepad etc). However, if I want to send things to a control like edit box INSIDE the window, I know that the window gets the message but the edit box does not.
This is due to the fact I get the HWND to the window of the target windo as
HWND wnd =::GetForegroundWindow()
Thus I tried to do this:
CWnd* pWnd = FromHandle(wnd);
CWnd* pFoc = pWnd->GetFocus();
I then use pFoc->m_hWnd in the AttachTHreadINput call
What is wrong here. I get some can not read from loc ??? error. What would I need to do to get the HWND to the actual control inside the window that has the focus FROM another program?
THanks for any advise.

Before I setup the Printer Setup dialog I wanted to set the paper size and orientation ect.
What I did was:
CPrintDialog PDlg(TRUE);
GlobalAlloc(GMEM_MEVABLE, sizeof(DEVMODE));
DEVMODE* pDevMode = (DEVMODE*) GlobalLock(PDlg.m_pd.hDevMode);
pDevMode-> ...
...
GlobalUnlock(PDlg.m_pd.hDevMode);
PDlg.DoModal();
According to MSDN this should be enough to initialize things before the call to DoModal, right?
Thanks for any suggestions.

I'm interested to know what version control ppl use at work. I'm currently evaluating visual sourcesafe with sourceoffsite for distributed team collaboration on code and also cvs on a linux machine with windows gui clients. One is free and the other is not but has anyone had any experiences with both or use something else?
|

We use SourceSafe and SourceOffsite here. biut I'm afraid I've got no experience of CVS.
This topic has been discussed pretty extensively in the Lounge, so I'd suggest a quick trail through the posts (don't worry, there's only 77,000 of them  ) would be a good starting point.
Just try setting the filter to "SourceSafe" or "version control" and you'll find plenty of information.

We have used WinCVS at work and found that on many occations it 'Lied' to us about diffs in files.
We also us Source Safe on projects where we use Visual Studio as it is conviently intergrated. A warning however if the SS database is on a UNIX server, be sure that the file system which contains the 'sepository' is not subject to quotas. If a user overruns the soft quota during the checkin process, it screws up the repository because the file will be integrated and the history update may not happen. This happened a number of times on a previous project I worked on and now I have insisted that source code is free of quotas, because we know that no matter which system you use the repository will only grow and not shrink.
Happy programming!!

I have imported office 97 (or maybe XP), no dll hell any more, now it is called com hell;
#import "D:\Microsoft Office.97\Office\Mso97.dll"
#import "c:\Program files\Common Files\Microsoft Shared\VBA\VBE.DLL"
#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBEEXT1.OLB"
#import "D:\Microsoft Office.97\Office\MSWORD8.OLB"
As i would like to support different office versions, i need "a bit" changed headers, so there wouldnt be any namespace conflict between different versions of imported librarys.
After checking tlh, i have encountered on #pragma start_map_region. What does it do?
|
|
|
|
|
The only thing I can think of is that start_map_region is a macro. Try searching for a definition...
Otherwise I'm afraid I can't help.

I write the following code to draw a radial gradient fill,but it goes to slowly.Can anyone help to correct the code,please?

pDC->SelectObject(pOldBrush);
}

pDC->Ellipse(&rc); is consuming over 70% of the time spent in your two functions (using a rectangle with size 200 by 200 and a memory DC)
You are painting the same areas over and over again, excluding the outermost part of the ellipse.

If you are taking in events, look for DocumentComplete (DISPID_DOCUMENTCOMPLETE) (DOM has been built, and is ready to be read/manipulated).
If not, check the readystate of the document with IHTMLDocument2::get_readyState

Hi,
I want to know how to programatically create key's
and values in the Registry..
A small example would be helpful
Thanks in advance
Sameer

You can use CRegKey like so:
CRegKey reg;
BOOL ret = FALSE;
if (reg.Create(HKEY_CURRENT_USER, "Software\\YourApp") == ERROR_SUCCESS) {
reg.SetValue("Value", "Name");
reg.Close();
}
