I really don't know why you want to optimize this code!?
give me the whole code of the function.
Don't try it, just do it!

Most time takes b=(BYTE)a . And it is impossible to make it works faster.
|
|

|

Please read my response. You can make "b = (BYTE) a " a LOT faster. It involves using a "fast ftol". Search google for that phrase.

I think you use static_cast rather than C style casts and ass /Qifist as a compiler swich to swich it on.
Or use assembly
#pragma warning (disable:4035)
__declspec( naked ) long Q_ftol( float f )
{
static int tmp;
__asm fld dword ptr [esp+4]
__asm fistp tmp
__asm mov eax, tmp
__asm ret
}

I want to use the activeX Listview from mscomctl.ocx in my mfc- project. I couldn't find any information about integration in mfc application. there is only a help for visual basic developers.

You are simply to open resource editor, insert an instance of list view control in dialog. Then everything is very simple.
If you want to use list control in nondialog windows, the following is an excerpt from MSDN:
1. Define the control in the view or window class.
2. Call the control's Create member function, possibly in OnInitialUpdate, possibly as early as the parent window's OnCreate handler function (if you're subclassing the control). Set the styles for the control.
Read more in: Visual C++ programming guide -> Adding User Interface Features -> Details -> Control Topics -> Using List Control

Thanks for the information. The Visual programming guide give me no information about the activeX Listview from mscomctl.ocx.
I need the functionality like the right part of the explorer (multiselect row, sort ...) therefore the MFC class CListCtrl have not included such features.

Hi! I got one small problem and I wonder if somebody could help me with this program in C++. Here is the program:
Const SND_ASYNC = &H1
Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal _
lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
' Play a WAV file.
'
' FileName is a string containing the full path of the file.
' If SyncExec is True, the sound is played synchronously
' Returns True if no errors occurred
Function PlayWAV(N:\sound\1.wav, Optional SyncExec As Boolean) As Boolean
If SyncExec Then
' play the file synchronously
PlayWAV = PlaySound(FileName, 0, 0)
Else
' play the file asynchronously
PlayWAV = PlaySound(FileName, 0, SND_ASYNC)
End If
End Function
Program is signing me an error in line 1. I don't know why. If somebody has a solution, please help me with my program!

You do realize that the code you've shown is VB and not C++, don't you?

have you tried using double backslash in the path name as in C++ and C a single backslash followed by a letter is a special case, e.g. \n is newline

ofstream outfile("F:\\test\\myoutfile.txt");
ifstream infile("F:\\test\\myinfile.txt");
ok!

Compiler doesn't looks for your files... that is not a compiler error !!!. is not a sintaxis error... because is a string... You know what I mean ??

I have to get back the static text on a dialog programatically. Say version number on help about dialog which will keep on changing .
But when the code like getwindow text executes the dialog is not active . So grtting invalid handle .please advise

assuming you have an object in your main program for this dialog and you are also using MFC, then you can assign a variable (CString probably) to the text box using the class wizard and then you should be able to access it in your main program (you may need to add a Get method).

the problem is that there is no gurantee that this object will be created in program lifetime. In fact if the user does not click on help->about , object is never created.
Suman ray
|
|
|
|
|
Couldn't you create the object in your constructor and then override the help->about method so that it just does "m_HelpDialog.DoModal ( ) ;" ?
This way the object will always exist during the program run.
Andy,

perhaps calling IsWindow(..) with the handle of the static control to receive the text from before doing so helps

Does anybody know how windows determines the background colour to use for static and group box controls?
At the moment I have a window (not a dialog) that contains a tab control which contains group, static and edit controls. This works fine if themes are not being used. If I enable themes the background colour for the static and group box controls is different to the colour of the tab control. It would appear windows is using the background colour from the parent window instead of the tab control. I'm wondering if windows uses different rules when the parent is a dialog?
Can anybody offer any suggestions?

Control colour's are set via WM_CTLCOLORXXX messages and the returned brush is used to paint the controls background, and the DC passed is used to paint the "foreground".
Theme's are probably getting in the way, and I'm not sure how they fit in the grand scheme of things - I guess you just have a app with a custom manifest file and it looks ok with themes off but not on.
I do remember seeing many apps - MS ones included - that have problems with Tab controls in XP.

Hi All,
Can someone tell me how to identify the font used by Windows Explorer when showing file names? Is it somewhere in the registry?
Thanks,
Chris

I belive it lives at:
HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics\IconFont
Though if I remeber correctly it's a pain as it's stored as a REG_BINARY along with some extra info.
