You are probably doing it in the wrong place. All painting should be done in response to a WM_PAINT message. Doing it elsewhere means that it will be overwritten the next time the window gets repainted.
Note: please put your code (properly indented) in between <pre> tags (use the code link above the edit window) so it is like:
if (IsDlgButtonChecked(hDlg, IDC_RADIO1) == BST_CHECKED )
{
EndX = LOWORD(lParam);
EndY = HIWORD(lParam);
SetROP2(hDC, R2_XORPEN);
MoveToEx(hDC, StartX, StartY, NULL);
LineTo(hDC, EndX, EndY);
IsDrawing = FALSE;
}
Use the best guess

hi , ,
"Use hardware acceleration when available " only exists on latest version of chrome.
I know that we can go to the Chrome menu > Settings > Show advanced settings > "System" > unselect "Use hardware acceleration when available" .
However I don't know path of file or path of registry so I can't change value of "Use hardware acceleration when available "
How to disable "Use hardware acceleration when available" using C++ .
Thanks

This setting is stored in a file called Local State.
The file is available in the folder C:\Users\<user>\AppData\Local\Google\Chrome\User Data
The contents of this file are in JSON format.
There is a section as follows -
"hardware_acceleration_mode": {
"enabled": true
}
Changing the value between true and false toggles this setting.
Make sure that chrome is not running when changing this value.

@Superman :thank you for helping me
I will check this way and we can modify value, and then The chrome can run normally .
Thanks

Hi,
I am very new to automation code Unit testing.I feel we can do Unit Testing using Boost Library for MFC code.So i tried for a sample example for its usage. I got a link from a link like - ''Designing Robust Objects with Boost[^] .Here he implimented for a DLL. But my application is a EXE(MDI application)and having lot of dependenies.
Hence i'm looking for more sample which shows Unittesing for EXEs and Mocking activity for the dependency.And all using BOOST C++ library. Now i'm using its latestes version. OR else any suitable TOOL suggested for the same purpose. Kindly help me soon.

Unit testing is done for code such as C++ classes or functions.
It will be the same for either a DLL or an EXE or however you package your code.

Thanks Superman for your suggestion.
In my case, as it is a MFC application, there is lot of predefined classes which are being used in my application(MDI). Like - CString , CWinApp, CSerialization, ... etc. So how to handle those predefined class or class's methods.
And some of the Dialog Boxes [Modal Dialog boxe] are there ,for them some input parameteres are there and some values are being returned from that dialog to the mail application. So for this we may have to create some Abstract class and some mocking lines need to handle the dependency. But i unable to implement the same. So i need some example implementation which may be easier to cath easily. Hence kindly help me .

You will need to stub out the predefined classes and some APIs.
You will also need to create other test harnesses to block out the UIs.
All these will not be very straight forward to implement.
I'm unable to show you code that I have since it is proprietary.
You will need to search the web to see if you can find any examples.
Since I learned them on the job, I'm not sure if there are any books available on this.

You are absolutely right.
It seems this methodology defintely fulfill my requirement.Since last 2 weeks i'm struggling for the same. Similar type of methodology, some has adviced me also. Unfortunately i unable to contact him.
Also i searched a lot from web,but faild to get any proper guidance. As i'm beginner to this area , iunable catch some of the web documents.
I should not ask like this and also it is hard to find out time.But my kind reqest to you. If possible can you please create a small Dialog based/ SDI/ MDI application and use BOOST library/any good tool for its unit testing. I know,for you it'll take maximum 1- 1.5 Hrs to do.Really i'm feeling bad while asking you to work for me, but i am really in a big trouble.
And i need to show some good progress by tomorow.So that i can give a confidence and i'll be able to implement for whole project .Hence kindly if you can able to prepare some protoype app(above), it'll be kind enough. So that i can able do some progres or it may enhance my confidence on further Unittesting work.Thats what my customer wants. Hence please try to help sooon.
Additianlly i need to look at test coverage activity too.
Thank you

Hi there,
I have been using a CMFCShellTreeCtrl inside an OutlookBar, and simply wanted to change the name label on it. The control itself works just fine. Creation is performed in the following way:
tree.Create(dwTreeStyle, rect, &bar, ID);
pOutlookBar->AddControl(&tree, strName, 2, TRUE, dwStyle);
Simply changing the contents of strName does not result in a change in the labeling of the control. The old name is still present. What is going on here?
many thanks..
|
|
|
|
|
Just a thought, might it be that what's displayed is some other property e.g. data or content?
|
|
|
|
|
The control is ultimately inheriting from CWnd; have you tried SetWindowText[^]?
Use the best guess
|
|

|

Thank you both for your suggestions. Ultimately I decided to use a different (simpler) type of control to achieve the functionality I wanted.
Still curious about this simple problem.. I will revisit it another time.
cheers..

i want to make circular progress bar control on my dialog??
How can operate on this?? Give some tips and idea!
From funcky coder..

Thanks to good tips.. Ill change on MFC Type,,
Maybe big work for me! YAY~

I want to make the flat control (2D look) instead of (3D), I can draw a rectangle or changing the color using custom draw
(DRAWITEMSTRUCT) but the changes behind the tab as the picture below, the black is my rectangle
http://social.msdn.microsoft.com/Forums/getfile/305523[Tab control 1 ]
I have changed my rectangle to OPAQUE but still the same thing
By the way the whole tab has that (3D), I have no idea why??
http://social.msdn.microsoft.com/Forums/getfile/305526[Tab control 2]
Can I remove that 3D look from the tab control?
And if the DRAWCUSTOM should deal with that Why my rectangle behind the tab it supposed to be on it for covering that tab?
Edit:
using
TCS_faltbutton and
TCS_BUTTONS does not solve this

I'm struggling at how to customize the console window background color. I have found that SetConsoleScreenBufferInfoEx may help me, but I don't know how to do it. I want to customize the background color like the properties window do. Anybody can help me?enter image description here
And now what I have is customize the foreground color with RGB, here is my code:
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFOEX csbiInfo;
csbiInfo.cbSize = sizeof(csbiInfo);
GetConsoleScreenBufferInfoEx(hStdout, &csbiInfo);
csbiInfo.ColorTable[6] = RGB(200, 255, 0);
SetConsoleScreenBufferInfoEx(hStdout, &csbiInfo);
SetConsoleTextAttribute(hStdout, 6);
The more I do, the more I can do!

After a bit of experimentation I found that setting the background colour and then sending a clear screen (cls command) will set the entire background to the selected colour. The only bit I cannot find, is how to send a clear screen command from code. In the old ANSI.SYS days it was done by <ESC>[2J, but that does not seem to work in command.com windows. However by adding a system("cls") call I can get the entire screen to the new colour. The following code sets the background to white.
SetConsoleTextAttribute(hStdout, BACKGROUND_BLUE | BACKGROUND_RED | BACKGROUND_GREEN);
system("cls");

How to customize the color with RGB ? This is the real question.
|
|
|
|
|
I don't think you can; the function accepts any combination of the single values [ RED | GREEN | BLUE ] which allows up to 8 colours (16 if you add the highlight flag). If you want full colour control then you should be looking to use a proper Windows application which lets you use the complete range of RGB values.
Use the best guess

I am creating a modeless dialog from an ActiveX which loads in the Internet Explorer 9/Windows 7 using following code:
Where CMyActiveXCtrl class is of COleControl type.
void CMyActiveXCtrl::OnBnClickedTest()
{
m_MainDialog.bClosed = false;
m_MainDialog.ShowWindow( SW_SHOW );
MSG Msg;
BOOL bRet;
while (bRet = GetMessage(&Msg, NULL, 0, 0))
{
if (bRet == -1)
{
MessageBoxA(this->m_hWnd, "Message loop error", "My ActiveX", MB_OK);
break;
}
if (PreTranslateMessage( &Msg ) == 0 )
{
if (!::IsDialogMessage(m_MainDialog.m_hWnd, &Msg))
{
TranslateMessage( &Msg );
DispatchMessage(&Msg);
}
}
if (m_MainDialog.bClosed == true)
{
break;
}
}}
m_MainDialog.bClosed set true on modeless dialog close/destroy. Now when my modeless dialog is opened in ActiveX and the user closes the browser window using IE > File > Exit or clicks on top right "X" button, IE main windows closes (no longer visible) but it leaves an orphan IE process in the task manager.
The same code working fine on Windows XP/ IE 8. Can anyone suggest me what could be the problem with above message loop in OnBnClickedTest() else without that message loop, it works fine.

Here is my guess:
Message order can be different with different window managers. Even on the same windows installation the window manager and the message order can be different if you change between aero/oldschool/whatever look.
One possible reason can be the following: when you press X the window receives WM_SYSCOMMAND/SC_CLOSE that triggers a WM_CLOSE that triggers WM_DESTROY that finally executes a PostQuitMessage() in a usual windows program. Pressing the Exit menuitem usually skips the first step of the chain and sends WM_CLOSE directly to the window. I think here the problem can be that your loop consumes the WM_QUIT message placed by PostQuitMessage() to the message queue (when your GetMessage call returns FALSE) so when you return from your loop the message loop of IE doesn't have any quit message to process. I'm not exactly sure about this (haven't tried it) because WM_QUIT isn't really a message in the message queue of your thread, its rather a bit that tells GetMessage()/PeekMessage() to return WM_QUIT when there are no more messages left in the queue, maybe this flag remains set but who knows... If the flag doesn't remain set (that can be windows version specific) then the problem can be what I described. When your main loop ends (GetMessage returns false) try to repost the quit message by calling PostQuitMessage((int)Msg.wParam) a the end of your OnBnClickedTest() function to place a WM_QUIT message (flag) in the queue for the main loop of IE. Try it and good luck with this.
Of course this disaster can happen only if the WM_QUIT is consumed and if WM_QUIT comes before the bClosed flag of your dialog becomes true. You can check that by placing a log into your bClosed checking if block and after the end of your loop.
EDIT: Another even better solution if you know the HWND of the main window: after checking the m_MainDialog.bClosed flag of your dialog put in another if block that checks whether this message is a WM_CLOSE message sent to the main window and in that case break out of your loop. An even better version of this: in your loop you should call PeekMessage() before every GetMessage() call just to look ahead in the queue (without removing the message) and if its a suspicious message sent to the main window (WM_SYSCOMMAND/SC_CLOSE or WM_CLOSE) then you break out your loop immediately without processing the message and you let the message loop of IE to process it. What is nice about this solution is that it would work even if the main loop of IE wanted to act on the WM_SYSCOMMAND/SC_CLOSE or WM_CLOSE message of the main window - putting such handlers into the main loop is not a good practice (you should handle that in the windowproc of the specified hwnd) but maybe MS guys committed that hack...
briefly:
for (;;)
{
WaitMessage();
PeekMessage();
if (WM_SYSCOMMAND/SC_CLOSE or WM_CLOSE sent to the main window)
break;
BOOL bRet = !GetMessage();
if (!bRet)
break;
}
EDIT: of course you know the HWND of the main window because you just have to call GetParent() on the HWND of the activex control or its window in a loop (or recursively) until it returns NULL HWND and the HWND before the NULL result is the top level window.
