Does anyone know how to get a list of all the thread handles in a process on Windows NT4.0? On Windows 2000 and Windows XP the toolhelp32 api can be used, but this is not available on Windows NT 4.0.
Also the process status helper library (PSAPI) has a function to enumerate all processes, but not all threads.
Note, I am interested in the thread handles, not the thread ids as I don't know of a way to get a thread handle if you know a thread id (that works on Windows NT 4.0).
Cheers

Correct me if i'm wrong here i'm a beginner.
Doesn't VC++ 6 have some tools for looking at threads etc... I've been playing around with them myself, however u may be looking for something a bit more techy than them.
I hope this will either ring a few bells in your or other visitors heads as to the matter.
.NET or not .NET? MFC is the question......

Use the Spy....
But if you want it prgramatically, for each process, you need to open new enumprocess for each process. The process are a tree, and pspi show you every level, you need to open every process for see if you have more sub process...

Hello everyone,
I thought of posting this in the operating system forum, but it has so little traffic I thought the question would be overlooked.
On Windows XP and Windows 2000 you can use:
HANDLE hThread;
DWORD dwProcessId;
dwProcessId = GetCurrentProcessID();
hThread = OpenThread(..., dwProcessId);
to get a handle to a thread if you know its thread id.
How do I do this on Windows NT 4.0? The OpenThread() function
does not exist in kernel32.dll on Windows NT 4.0.
Hoping someone can help. Kernel mode device driver solutions
are valid, I'll consider any method to get this info.

MSDN says:
Windows NT 4.0 and earlier, Windows 95/98/Me: There is no way to get the thread handle from the thread identifier. If the handles were made available this way, the owning process could fail because another process unexpectedly performed an operation on one of its threads, such as suspending it, resuming it, adjusting its priority, or terminating it. Instead, you must request the handle from the thread creator or the thread itself.
A thread can use the GetCurrentThread function to retrieve a pseudo handle to its own thread object. This pseudo handle is valid only for the calling process; it cannot be inherited or duplicated for use by other processes. To get the real handle to the thread, given a pseudo handle, use the DuplicateHandle function.

I would like to implement a resizable dialog box with controls in the dialog box resizing along with the dialog borders. I tried adding guides and margins in the Microsoft Dialog Editor, but these margins do not seem to resize along with the dialog borders. Can anyone let me know how I can resize items along dialog borders?
Thanks in advance.

Hey,
First off if this is a really silly question then please excuse me but this is my first attempt at writing an application in c++.
I am trying to write a c++ program that can access a SQL Server database through ODBC/ADO(I don't care how just want it to work). I get c2059 error : 'constant'on the following line:
hr = m_pConnection->Open(_bstr_t(L"driver={sql server};SERVER=(local);Database=loggy;"),_bstr_t(L"sa"),_bstr_t(L"choices"),adModeUnknown);
Every command run after this complains about not being a member of _connection. I am using #import to import the msado15.dll whcih seems to be the best way(after many surfing hours). I would apreciate it if any one could help me. I think I have just put some code in the wrong place or something.
Thank you in advance
Regards
Adam

I have lost the Admin password to a VSS database. Without this I can no longer run the SS Admin tool. Does anyone have an idea of how to recover for this situation? 
Thanks.

After a couple of hours searching through Google, I hit this great link.
http://groups.google.com/groups?q=VSS+ADMIN+PASSWORD&selm=93v9ll%24ldt%241%40nnrp1.deja.com&rnum=6
It gives a procedure for removing the password requirement for Admin. You use a hex editor to replace some values in the database's um.dat file and presto, you can now start the Admin utility without being prompted for a password.
Hope this helps out someone else.

Please Explain to me why you will not get an error.

This is simple. The function "OnFileOpen" is local to three different classes, namely CMyView, CMyFrame and CMyDoc. You would get an error if they were declared as global.

If you have command handlers in view, frame and documents, then the framework will call the one in view only. If there is no handler in your view class, then the framework will try to dispatch the command in your frame class.
This might be more clear if you look in the MFC source code (in "winfrm.h", MFC7), where the message is actually dispatched.
BOOL CFrameWnd::OnCmdMsg(UINT nID, int nCode, void* pExtra,
AFX_CMDHANDLERINFO* pHandlerInfo)
{
CPushRoutingFrame push(this);
CView* pView = GetActiveView();
if (pView != NULL && pView->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
return TRUE;
if (CWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
return TRUE;
CWinApp* pApp = AfxGetApp();
if (pApp != NULL && pApp->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
return TRUE;
return FALSE;
}
Hope this helps.
Regards.

Hello again everyone, and Happy New Year.
I'm relatively new to VC++ so I'll try to explain this the best I can. Here's my situation... I have an SDI app where the MainFrm is CSplitterWnd'ed into several different views. I have one view that is a "keypad" (CView) with a bitmap that resembles a standard keyboard numpad. If the user presses any numpad buttons, I want that view to "see" and process those window messages. The following snippet is how I'm trying to do it, but it doesn't seem to receive any messages. What am I missing??
// ==================================================================
void CMainFrame::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
ASSERT( GetActiveDocument() );
CClocksterDoc* pDoc = static_cast<cclocksterdoc*>(GetActiveDocument());
int iQty = 0;
switch(nChar)
{
case VK_NUMPAD1: iQty = OES_KEY_01; break;
case VK_NUMPAD2: iQty = OES_KEY_02; break;
case VK_NUMPAD3: iQty = OES_KEY_03; break;
......
}
if( iQty > 0 )
{
pDoc->DoPurchaseRequest( iQty );
}
CFrameWnd::OnKeyDown(nChar, nRepCnt, nFlags);
}
// ==================================================================
I hope explained this well enough.
Thanks...

It's the view that receives key-down messages and not your CFrameWnd derived window
Nish
p.s. from cafe. so anony post

Thanks Nish. That works, but only when it has the focus. Is there a way to force the view to always receive the key-down message??
Thanks.

You maybe interested in system wide event hooks.
Lookup SetWindowsHookEx
|
|
|
|
|
Just telling you that you have to do all hooks in a DLL if you want to catch when a key is pressed while your app is in no focus!

Richard Jacko & Rickard Andersson & All,
First, thanks for the reply. I think I'm headed in the right direction.
Secondly, I'm very new to Windows programming so I'd like to apologize for my "Windows ignorance"  . Please bear with me...
From reading the docs on SetWindowsHookEx, I assume that I want to set the idHook = WH_KEYBOARD, right? Then, I have to write a DLL with a procedure that will handle the message (which I've never done).
Is this all correct?  Thanks.
Marcus

I have the following code that will attempt to print various files without the need of Print Previews etc.
temppath = patharray[0].Left(patharray[0].ReverseFind('\\')+1);
temppath += "ReportFiles\\My file.html";
ShellExecute(NULL, "print", temppath, NULL, NULL, NULL);
filestring.Format("Production sheet has been printed.", tempfile);
m_misc.InsertItem(12, filestring, 1); UpdateWindow();
However, when the print dialog appears I get the following error message appearing in a message box:-
"Cannot find the file 'D:\Test\ReportFiles\My file.html' (or one of its components). Make sure the path and filename are correct and that all required libraries are available."
Despit this message the file is found and prints OK!?!?! Is there any way to avoid this message from being shown.
Also, I would like to not have to show the print dialog box so that it will automatically print on completion of a task. Is there any way of doing this and also to print multiple copies of the report.
Any constructive suggestions would be greatly appreciated.
Cheers,
James

Ok I'm going to take a couple of guesses
1.)
ShellExecute uses the default file association in your case "html" to open the document.
So in effect you are probably using your browser to print for you. And probably you are using IE4+ to do your dirty printing.
Check to see it's just not your PC that has this problem,
(Us coders are quite likely to abuse file associations on development boxes)
So maybe your code will run OK on a neighbours PC but not yours.
2.)
Consider changing your NULL paramaters to empty variants, And turn off the "Active_Dektop"
3.)
Try using OLECMDEXECOPT_DONTPROMPTUSER
as a paramater, I think its the third one ?
4.)
Make sure your Browser can actually print without errors ocurring.
