I only need to use a command prompt for my program and want to call a couple of WMI methods.
All the examples I see on the web use MFC and Windows Forms for showing how to use WMI.
A simple example would be to just call
Win32_WindowsProductActivation.SetProductKey( myKey );
and then close the app.
I just need a start on what I need to include and do to setup a simple call without using forms.
I am not that familiar with MFC Forms, only .Net Forms, but I do not want to have to install the .Net framework so I thought i would just write this in C++. Also, do not want to use VB Script.
Well, hopefully this is easy for someone to whip up an example for me.
Much appreciated.
Thanks.

I write this 3D editor at
http://marius.homeunix.org:8000
I've moved the compilation process in a thread. ()
The thread has to update the progress bar of the Dialog-Bar
and the text in the static and report list box.
I'm sending WM_* messages to these windows.
Under Win2K work 100% OK but in Win 98 it hangs
in the SendMessage (dead lock). Any Ideeas
Thanks.

Did you try using PostMessage?...

I have to send text to the static control
TCHAR someOutString;
_stprntf(someOutString,"Preogress is :%d%%",_percentage);
dlgbar.m_static.SendMessage(WM_SETTEXT,0,(LPCTSTR)someOutString);
If I do PostMessage I loose the LPARAM ... 'someOutString'.
I have installed VC 6 under 98 and I I get hang in user.dll
Thx

>> I have to send text to the static control <<
So what? You may have different options, e.g:
1. Put your TCHAR someOutString as global variable acessed by both threads;
2. Allocate yours someOutString on sending thread and free on receiving...
>> I get hang in user.dll <<
The reason for hang could be limited message queue on Win98...

Opps... It works.
I did it and It works fine. Thank you. Anyway I have overmessage there
Now I SendMessage() 1-3/sec. and is OK.
{
static int modul = 0;
if(modul++%64 == 0)
{
UpdateProgressBars()
}
}
Thanks. Igor.

OK, that confirms that the reason for a deadlock is limited queue on Win98.
Hope 3 seconds is fine, but it's still not be 100% bullet prooof. I don't see any solution other then PostMessage. With PostMessage also you can check on your sending thread that only one WM_SETTEXT is travelling and Post only if nothing is in queue.
For example if your string is global and sending thread sets it and receiving empties it --> you will only PostMessage if that global string is empty...

I have studied the instruction setting up a C++ project to use CxImage at http://www.codeproject.com/bitmap/cximage.asp.
But I still need help to generate/find the library files. I downloaded the source files and did a build on the project. But I do not see the library files stated in the instruction, for example, jpeg.lib.
Please help.

I just found out how to generate the lib files. I have to select a Configuration before the build.

How can I get a DLL's version programmically?
Thanks

Assuming it has one, try VerQueryValue(), GetFileVersionInfo(), and related functions.

So inorder to get the version I have to use all three of those functions listed in the MSDN? There's no easier way?
By the way is the answer 2?
Thanks

Yes, you'll need to call GetFileVersionInfoSize(), GetFileVersionInfo(), and VerQueryValue(), in that order.

It's easy once you've done it a few times. Now if you have no interest in how it all works, you can always skip to this class.

The application lost the toolbar tooltips after the SetState statement
m_wndToolBar.GetToolBarCtrl().SetState(ID_INBOX, TBSTATE_HIDDEN)
If I comment this line out, the tooltips comes back.
I tried to get the tooltips back by adding the following line
m_wndToolBar.SetBarStyle(m_wndToolBar.GetBarStyle() | CBRS_TOOLTIPS)
But this does not work. The tooltips are not showing up at the toolbar.

Hi!
I am building a chat application and I'd like the main chat window to scroll down (such that the last message is at the bottom of my CRichEditCtrl) when the user enters a message.
I have not been yet able to do this. I know about LineScroll, but how many lines should I scroll with it? (Because the user can move the scroll bar upwards whenever he wants.)
Thanks!

How about this:
long lPos = GetRichEditCtrl().GetTextLength( );<br />
GetRichEditCtrl().SetSel( lPos, lPos );
"...Ability to type is not enough to become a Programmer. Unless you type in VB. But then again you have to type really fast..."
Me
|
|
|
|
|
This doesn't work.
From SetSel()'s help:
"This function does not scroll the contents of the CRichEditCtrl so that the caret is visible."
Other ideas?

Yes, you are right, SetSel function does not scroll the contents...
However, I think that the user will be annoyed if he decides to scroll up and see for example history of messages and at that time another message arrives and your code will scroll down. I think it's not right.
So, think about it: maybe you don't have to scroll. Just append new message to the end. In that case SetSel helps.
Not insisting of course:
void CChatView::AddString(LPCSTR lpszStr, COLORREF color )<br />
{<br />
LONG nStart, nEnd;<br />
GetRichEditCtrl().GetSel( nStart, nEnd );
LONG nLength = GetTextLength( );<br />
<br />
long lPos = GetRichEditCtrl().GetTextLength( );<br />
GetRichEditCtrl().SetSel( lPos, lPos );
<br />
GetCharFormatSelection();<br />
m_charformat.dwMask = CFM_COLOR;<br />
m_charformat.dwEffects = NULL;<br />
m_charformat.crTextColor = color;<br />
GetRichEditCtrl().SetSelectionCharFormat(m_charformat);<br />
Edit_ReplaceSel(m_hWnd, lpszStr);<br />
<br />
if((nStart != nEnd)&&<br />
(nLength > nEnd + 10))<br />
GetRichEditCtrl().SetSel( nStart, nEnd );
}

The user won't be annoyed, because I want this scrolling to take place only when HE enters the message (and not his chat partner), so that he doesn't have to scroll down to the last line and then enter his message.
Thanks anyway!

Here's a really late response for you, and I understand that you will probably already have a solution. But my searching around on the net didn't find much more than your question and a lack of an answer. Hope this helps someone else.
This works for me:
CRichEditCtrl results(myEditBoxHWND);
LONG lLen = results.GetWindowTextLength();
results.SetSel(lLen, lLen);
results.ReplaceSel(_T("My new bit of text\n"));
int nFirstVisible = results.GetFirstVisibleLine();
int nTotalLines = results.GetLineCount();
results.LineScroll(nTotalLines - nFirstVisible);Phil

When I select various items in a CListCtrl they are obviously selected because the background colour changes.
However, when the CListCtrl looses focus, the items are not obviously in focus. Is there anyway I can change this so it behaves more like Windows Explorer and leaves the selected items selected, but a different colour when the window is out of focus.
Many thanks,
Alan Dugdall

Check the list control's "Show selection always" property in the resource editor. You can also set this style programatically by doing:
DWORD dwStyle = ListView_GetExtendedListViewStyle (m_listCtrl.GetSafeHwnd());
dwStyle |= LVS_SHOWSELALWAYS;
ListView_SetExtendedListViewStyle (m_listCtrl.GetSafeHwnd(), dwStyle);
