how to disable "Use hardware acceleration when available" on chrome

8-Jul-13 5:42

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:

C++

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.

BOOST C++ Library for MFC application

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 Smile | :)

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[^]?

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..

Tab control with custom draw?

JoneLe866-Jul-13 7:35

6-Jul-13 7:35

I want to make the flat control (2D look) instead of (3D), I can draw a rectangle or changing the color using custom draw

C++

(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

C++

TCS_faltbutton

and

C++

TCS_BUTTONS

does not solve this

how to set entire console window background color with given RGB(SetConsoleScreenBufferInfoEx)?

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:

C++

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!
