I'm afraid the .ini file syntax hasn't been specified too clearly by MS or whoever.
Since it is not detailed what a string to be read by Get(Private)ProfileString(),
I won't make any assumptions regarding special characters.
The only comment I have yet come across is the single line comment, that is a line
starting with a ';'
A rest-of-line comment would demand specific treatment of the ';' character.
It seems to be unimportant wether the '=' is surrounded by whitespace or not.
To get slightly more (and less) control of how an .ini file is accessed, use
Get(Private)ProfileSection(), which reads a whole section into memory.

1. What is the best way to reboot the system which is really not platform specific?
ExitWindowsEx seems to be the function, but it has too many
platform restriction. I tried looking for a KB but could not
find anyone on this.
Any help?
2. I have a simply installation startup, which will install some system stuff like DCOM95/MDAC/50COMUPD/HHUPD before executing the main program to be installed.
Most of the updates require a reboot, and I use the RunOnce registry key to automatically restart the installing steps.
The problem is the main installation is Windows Installer
based program and I wish to follow the tradition here to allow the user access to the desktop. However, with the RunOnce key, Windows seems to wait for the program to complete before displaying the desktop. Is there any good way to yield control to Windows to display the desktop?
Best regards,
Paul.

The ExitWindowsEx function will work on all Windows platforms, but under NT/W2k/XP, you will have to check and/or modify the system privileges to enable the ExitWindowsEx call to work correctly.
See this link on CodeGuru for some code:

It seems that WS_EX_LEFTSCROLLBAR style is not working with combo boxes - has anybody found a solution to that?
Even thought there is a property called "left scrollbar" in the resource editor, it does not change a scroll position. ModifyStyleEx is also not working...
|
|
|
|
|
It works on my Win2000 box. Are you sure that you have enough items in your combobox to actually display the scrollbar? Combos with no items display no scrollbar at all.

Yes, it filled with items and I have a scroll bar but in the usual place, that is on the right. I am on NT4 thought - gottat test it at home with w2k...
Using a SPY++ I can see that the drop style has changed if I use ModifyStyleEx against the ListBox part of combo only, the resource editor only changes the style of the edit part. I tried all the combo types - simple, drop down and list to no avail... Strange...
Dziekuje za pomoc.

From the CreateWindowEx docs in MSDN:
"WS_EX_LEFTSCROLLBAR: If the shell language is Hebrew, Arabic, or another language that supports reading order alignment, the vertical scroll bar (if present) is to the left of the client area. For other languages, the style is ignored."
Have no idea what if W2K US-English shell supports Hebrew, Arabic or reading order alignment. Seems that you can forget about this style if your app is going to run on different Windows versions.

Yeah, it looks like it works on my "English-speaking" w2k as well.
How annoying is that!

Hi all,
I have two application, A.EXE and B.EXE. The two applications communicate using OLE Automation method. A.EXE is the server and B.EXE is the client. Now, I want B.EXE to pass a HWND to A.EXE, and A.EXE will draw image at the given HWND. I can't make it.
CWnd::FromHandlePermanent(hWnd) return NULL.
I would like get advice from codegurus here whether this approach is possible or not. If not, is there any other method to do so?
thanks
regards,
yhtay

No.

|

Is the HWND just the handle to the main window for B.EXE ? If so, why not just enumerate the windows and find it that way ? Or use Copydata to send the info between processes ?

Thanx in advance for the Help .

Hi there, can someone give me an idea as to why this code:
/*****************************************************/

/*****************************************************/
CRect rect;
CFont TextFont, *oldFont;
CWnd *wnd = GetDlgItem(IDC_PLACEHOLDER); // find where to put the text (a static control)
ASSERT(wnd != NULL);
ASSERT(IsWindow(wnd->m_hWnd) != FALSE);
wnd->GetWindowRect(&rect);
ScreenToClient(&rect);
CPaintDC dc(this) ; // device context for painting
if (m_dc.GetSafeHdc() == NULL)
{
m_dc.CreateCompatibleDC(&dc) ;
m_bitmapTitle.CreateCompatibleBitmap(&dc, rect.Width(), rect.Height()) ;
m_pbitmapOldTitle = m_dc.SelectObject(&m_bitmapTitle) ;
}
TextFont.CreateFont (40, 0, 0, 0, 300, // Create the font
TRUE, FALSE, 0, ANSI_CHARSET,

oldBitmap = (CBitmap *)memDC.SelectObject(&memBitmap) ;
if (memDC.GetSafeHdc() != NULL)
{
// draw the text on the memory dc
memDC.BitBlt(0, 0, rect.Width(), rect.Height(),
&m_dc, 0, 0, SRCPAINT) ;
// bitblt the result to the display DC
dc.BitBlt(rect.left, rect.top, rect.Width(), rect.Height(),

}
memDC.SelectObject(oldBitmap) ;

produces perfectly fine output on Win NT but garbage on win 95/98/Me?? I'm stuck!! 
to understand what I mean about garbage, please see Win NT and Win98
Thanks in advance for any help!

Without a real context (not a DC context) it's pretty hard to tell.
I can however tell you that you're in error to not check the return codes from each and every function above why I'd say you deserve the errors. After you've added those checks, perhaps you can see for yourself what went wrong? If not, that would be a good point to ask this question.
P.S.
If you're the "Senior Test Engineer" for that company, would you mind telling me what products you sell so I know what to stay clear of?

The code I posted was a cut and paste into a demo project, I removed a lot of stuff to make it more readable and easy to see what I was trying to do.
We don't sell any products, so rest assured you need not live in fear of coming across any software that might hurt your pwetty wittle compewter....
I'd be more than happy to tell you the products we test, but wait, what's that?? you're anonymous, silly me...
Thanks for the constructive criticism...

I've rewritten your function, I hope you find it a little neater 
/*****************************************************/
/* draw some text */
/*****************************************************/
CRect rcWnd;
CFont TextFont, *oldFont;
CWnd *wnd = GetDlgItem(IDC_PLACEHOLDER); // find where to put the text (a static control)
ASSERT(wnd != NULL);
ASSERT(IsWindow(wnd->m_hWnd) != FALSE);
wnd->GetWindowRect(&rcWnd);
ScreenToClient(&rcWnd);
CDC placeDC;
if (!placeDC.Attach(wnd->GetDC()->GetSafeHdc()))
ASSERT(FALSE);
if (m_dc.GetSafeHdc() == NULL)
{
if (!m_dc.CreateCompatibleDC(&placeDC))
ASSERT(FALSE);
if (!m_bitmapTitle.CreateCompatibleBitmap(&placeDC, rcWnd.Width(), rcWnd.Height()))
ASSERT(FALSE);
m_pbitmapOldTitle = m_dc.SelectObject(&m_bitmapTitle) ;
m_dc.FillSolidRect(0, 0, rcWnd.Width(), rcWnd.Height(), ::GetSysColor(COLOR_3DFACE));
}
if (!TextFont.CreateFont (40, 0, 0, 0, 300, // Create the font
TRUE, FALSE, 0, ANSI_CHARSET,
OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,
PROOF_QUALITY,
DEFAULT_PITCH|FF_SWISS, "Arial"))
ASSERT(FALSE);
oldFont = m_dc.SelectObject(&TextFont); // select the font
m_dc.SetTextColor (RGB(128, 0, 0)) ; // set a bunch of attributes of the dc
m_dc.SetBkMode(OPAQUE);
m_dc.SetBkColor(::GetSysColor(COLOR_3DFACE));
m_dc.SetTextAlign (TA_LEFT);
CString Title = "Test ";
m_dc.TextOut(0, 0, Title);
m_dc.SelectObject(oldFont) ;
placeDC.BitBlt(0, 0, rcWnd.Width(), rcWnd.Height(), &m_dc, 0, 0, SRCCOPY);
Basically your problem was that a CBitmap created under 98 using CreateCompatibleBitmap is full of random garbage. The line
m_dc.FillSolidRect(0, 0, rcWnd.Width(), rcWnd.Height(), ::GetSysColor(COLOR_3DFACE));
fixes this. You should have had text in the top corner though, but I'm not sure why you did not as I did a partial rewrite to get rid of unnecessary DC's, etc.
Where in Australia are you ? ( I'm in Tassie )

I noticed, just today, that IE has an interesting feature when organizing your favourites list. What I noticed is a line appears under an entry when you drag over it. It appears that the line is indicating where the item will be dropped. What this means to me is that a folder can be repositioned within the list rather than becoming a child of the target. I would like to do the same thing but have no idea how. I see this same type of thing in other products, Netscape and DemoShield. Can anyone help me? Try it yourself if you have not experienced this yet!

Check these methods:
CTreeCtrl::SetInsertMark
CTreeCtrl::SetInsertMarkColor
They're simple wrappers around TVM_SETINSERTMARK and TVM_SETINSERTMARKCOLOR messages, supported on COMCTL version 4.71 and later. Basically this means that target machine must have IE 4.0 or later installed.

does anyone know how make a window active when multiple windows are open.
in an mdi applicatin under window menu item there is a list of all open files and the active
one is checked, i want to know how that code works, so that when i click on my tree node
that window should be activated,
Thanks,
F.Dost
|
|
|
|

Yeah its pretty easy,
use the SetActiveWindow (hwnd ) function.. You need to get the window handle for the window you want to activate though..
Do that by
hwnd = FindWindow(NULL, "Put the window title here")
SetActiveWindow (hwnd )
|
|
|
|
|
If you are talking about the MDI "document windows", you need to send WM_MDI* messages to the "MDI client", the window that is usually in the dark gray colour.
