send F5 key to browsers using PostMessage - c

I loaded "html.html" file in Firefox browser and used the following code to refresh it which works fine.
int main()
{
HWND v;
v = FindWindow(NULL, "Mozilla Firefox");
if (v == NULL)
print("not found");
else
{
print("found");
PostMessage(v, WM_KEYDOWN, VK_F5, 0);
PostMessage(v, WM_KEYUP, VK_F5, 0);
}
}
I loaded the same file in Google Chrome browser and modified the window title in the previous code to "html.html - Google Chrome". The code finds the window but the browser is not refreshed. The same (no refresh) happens with Opera and Microsoft Edge.
What am I missing here?
EDIT 1:
I used the following to send Ctrl+F5, but I still cannot refresh Chrome.
PostMessage(v, WM_KEYDOWN, VK_CONTROL, 0);
PostMessage(v, WM_KEYDOWN, VK_F5, 0);
PostMessage(v, WM_KEYUP, VK_F5, 0);
PostMessage(v, WM_KEYUP, VK_CONTROL, 0);
EDIT 2:
(After being asked about tests with other automation software.)
I prefer to use pure WinAPI. Also, I already have the right key because F5 is used to refresh those browsers. To prove that, I called SetForegroundWindow() before sending the key and it will refresh all browsers.
But I cannot use SetForegroundWindow() because I need to keep the browser in the background, also calling this function is just overhead since without it, the code works fine for Firefox.
So what is the difference between Firefox and the others in this specific matter?

Automate Chrome with window handle

I am working on a project in c which i am trying to simulate chrome browsing.
my only difficult is to find a way to get links position on screen after i receive a handle to chrome window. anyone knows how to get the links position??
i am familiar with selenium and managed to do so in python but i require to do so in c too.
any ideas?
int wmain()
{
HWND hwnd = NULL;
for (;;)
{
hwnd = FindWindowEx(0, hwnd, L"Chrome_WidgetWin_1", 0);
if (!hwnd)
break;
////Get Links position
}

cookies validation using selenium

I am new to selenium. Actually I am working on some cookie validation project, which requires me to manually check the cookies present before and after clicking on some consent link in multiple browsers (Firefox, ie, chrome, safari).
Previously in the phase 1 project I ran a qtp script to treat the firefox as a window object and capture screenshots, but that is quite troublesome if the resolution changes or any minor look-n-feel changes. Also it is quite difficult to manage and it works on firefox only and I needed to write the same script again for chrome and safari. Apart from this since QTP is licensed product and currently we are using seat license so I can't run it on multiple machines to speed up execution.
So I thought moving to Selenium. As of now my requirement is:
1. open the page - take the screenshot once page loaded.
2. check the cookies using firebug or any other way - take the screenshot
3. click the link to close the consent - take screenshot once consent closed.
4. refresh the page and again check the cookies using firebug - take screenshot
So I done some research on selenium and found that I can validate the cookies using verifyCookie but still I need screenshot of firebug window for cookies. So I got stuck here.
please help me out here..
I found some possible way to do this on Firefox but now I was looking forward for something similar for Chrome if that possible. Thanks
Selenium cannot interact with firefox extensions, or the browser in the way you want it to.
What you can do is collect a list of cookies on the page by doing:
driver.manage().getCookies()
This will give you a list of all cookies that are visible to Selenium. Please note that this is the same as the cookies that are visible in the JavaScript console (Not all cookies are visible via JavaScript, for example cookies set with the HTTPOnly attribute) using:
document.cookie
I would suggest you use getCookies() to programatically validate the cookies.
In selenium IDE if you want to take screenshot of the page use captureEntirePageScreenshot command
captureEntirePageScreenshot | D:\\test.png |
D:\\test.png - path of file where you want to save the file
Got some solution

firefoxProfile.setPreference(domain + "defaultPanelName", "cookies");
WebDriver driver = new FirefoxDriver(firefoxProfile);
driver.get("http://www.google.com/webhp?complete=1&hl=en");
WebElement query = driver.findElement(By.name("q"));
query.sendKeys("Cheese");
query.sendKeys("\n");
Robot robot = new Robot();
BufferedImage img = robot.createScreenCapture(new Rectangle(new Dimension(1024, 768)));
File path = new File("E:\\abc");//Path to your file
if(path.getName().indexOf(".jpg") == -1){
path = new File(path.getPath() + ".jpg");
}
ImageIO.write(img, "jpg", path);
}
}
might be useful.

Launch default web browser, but not if URL already open

I have a link on my app UI that launches a URL using System.Diagnostics.Process.Start(). If the user clicks the link several times, it opens several tabs.
Is there a way, maybe a command-line option, to still use the default web browser, but have it just reopen the same tab if the URL is already open? It would be OK if it doesn't work with every possible browser out there, but nice if it at least works with IE, Firefox and Chrome.
I doubt it, but since I didn't see any other questions/answers on this topic, I figured I'd ask.
This is somewhat of a workaround but it might get you started. I have used the System.Diagnostics.Process.ProcessId.
As an example I have used IE, I will explain later why I did this. The code is just "quick and dirty" but I just made it as proof of concept.
I have created a basic WinForm app with one button that will open google in IE, if it has already been opened by the application it will not be opened again.
I added the System.Diagnostics reference.
public int ProcessID;
public Form1()
{
InitializeComponent();
}
private void MyButton_Click(object sender, EventArgs e)
{
if (ProcessID == null)
{
StartIE();
}
else
{
if (!ProcessIsRunning())
{
StartIE();
}
}
}
private bool ProcessIsRunning()
{
bool ProcessRunning = false;
foreach (Process p in Process.GetProcesses())
{
try
{
if (p.Id == ProcessID)
{
ProcessRunning = true;
}
}
catch { }
}
return ProcessRunning;
}
private void StartIE()
{
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "iexplore.exe";
proc.StartInfo.Arguments = "http://www.google.be";
proc.Start();
ProcessID = proc.Id;
}
This does not completely do what you requested but it might be a good start. There are a few reasons why I did it this way and what possible options are..
If you would use the url as the Filename, it would indeed open up the webpage in the default browser, it would however not return a processID. This is why the snippet shows usage of IE. (If you would use this option, you could use the System.IO.File.Exists to make sure the desired browser is installed)
If you would like to use this option, you can query the registry to pick up what te default browser is, if you have that you could launch that from the value obtained from the registry. If you then change the process.startinfo.filename to this value, then you will launch the default browser but you will still obtain a processId so this might be the way forward. You can check how to do this over here: http://social.msdn.microsoft.com/Forums/en/netfxbcl/thread/b200903e-ce69-4bd4-a436-3e20a7632dc4
Showing the internet window if it would already be opened, can be done by using the SetForegroundWindow property. As this is already documented in this article, I did not add it in this snippet.
I hope this helps to get you on your way.

How to create a win32 application without window in background with C?

The application do not need any window or console. It can be a console application if the console window can be removed or can be put into background. The application will do some simple tasks(such as cleaning rubbish files) and exit.
I hope that the application should not be a windows service if possible.
I hope that the application can be started with double-click in explorer window and run silently.
When the application is running, I hope that the mouse cursor should not be changed to hourglass shape. That is to say, do not disturb the user when the application is running. Just run and exit silently.
DO NOT NEED to run it when windows starts or user logins.
I hope this can be done in C if possible. What should I do?
task_finished = 0;
CreateThread(NULL, 65535, task_thread, para, 0, NULL);
MSG msg;
while(!task_finished){
while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) {
if(task_finished)
break;
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
IIRC, you can do this by just writing a WinMain function that doesn't create or display a window or console. Lambert's answer about using a message loop will help you if you want your program to be able to send or receive messages from other programs, but if you're just doing simple background processing all you should need is a WinMain that doesn't make a window.
All you need is a message loop -- just use this code (modified from here):
MSG msg;
BOOL bRet;
while ((bRet = GetMessage(&msg, NULL, 0, 0)) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
Edit:
For I/O or other tasks, you can either (1) create another thread, and do everything from there, or (2) Use MsgWaitForMultipleObjects inside the loop (before the next GetMessage() call) to simultaneously wait on your I/O and on messages, so that you can be notified when there's either a message, or when your I/O is finished.
Warning:
I haven't figured out how to make the application not bring up the hourglass shape when starting. If you need that functionality, consider creating a Windows service instead. You can also compile as a console application, then use FreeConsole to hide the window.

Programmatically press a button on another application (C, Windows)

I'm trying to use the following code to press a button on my other application:
HWND ButtonHandle;
if( (wnd = FindWindow(0, "Do you want to save?")) )
{
ButtonHandle = FindWindowEx(wnd, 0, "SaveButton", "&Save");
SendMessage(wnd, WM_COMMAND, MAKEWORD(GetDlgCtrlID(ButtonHandle), BN_CLICKED ), (LPARAM)ButtonHandle);
}
It doesn't work. I tried passing different handles to MAKEWORD and to change the WPARM and LPARAM but nothing.
Any ideas on how to click a button on another application's window?
Code is appreciated.
Thanks.
EDIT:
The reason it doesn't seem to work permissions. I sent a PostMessage() and the result was an error with GetLastError() = 5 (or Access Denied).
Any ideas?
EDIT2 I don't mean to be rude but please please please, I already searched all the API's including getting and setting the regions for the button and then sending a button down and button up, getting the control ID, getting the class ID and a zillion more.
The reason I asked the question here in the first place is because I already exhausted my search on the internet.
If you know the answer PLEASE POST CODE, do not suggest an API and that's it, show me how does that API solves the problem. It's not hard.
thank you.
EDIT 3: The question's answer was selected automatically when the bounty finished. The question still remains without an answer.
Are you sure that "SaveButton" class name is valid? Do you get the button
handle?
Try to send messages to ButtonHandle window (directly to the button).
Update: I believe this should work,
SendMessage(ButtonHandle, BM_CLICK, 0, 0);
See the following solution, also you can use
SendMessage(ButtonHandle, WM_LBUTTONDOWN, 0, 0);
SendMessage(ButtonHandle, WM_LBUTTONUP, 0, 0);
Or
SendMessage(ButtonHandle, BM_CLICK, 0, 0);
HWND buttonHandle = 0;
BOOL CALLBACK GetButtonHandle(HWND handle, LPARAM)
{
char label[100];
int size = GetWindowTextA(handle,label,sizeof(label));
if(strcmp(label,"&Save") == 0)
{
buttonHandle = handle;
return false;
}
return true;
}
void main()
{
HWND windowHandle = FindWindowA(NULL,"Do you want to Save?");
if(windowHandle != 0)
{
BOOL ret = EnumChildWindows(windowHandle,GetButtonHandle,0);
if(buttonHandle != 0)
{
LRESULT res = SendMessage(buttonHandle,BM_CLICK,0,0);
//SendMessage(buttonHandle,WM_LBUTTONDOWN,0,0);
//SendMessage(buttonHandle,WM_LBUTTONUP,0,0);
}
}
}
Note:
Getting sure from the window text,button text (check if there is space at the end of the window title)
SendMessage(btnHandle, WM_LBUTTONDOWN, 0, 0);
SendMessage(btnHandle, WM_LBUTTONUP, 0, 0);
SendMessage(btnHandle, WM_LBUTTONDOWN, 0, 0);
SendMessage(btnHandle, WM_LBUTTONUP, 0, 0);
You have to send a button click twice. Not sure why (maybe the first click only activates the window of the button), but I'm using this code for a long time and it always worked for me.
maybe this can help:
http://www.cplusplus.com/forum/beginner/8806/
Access Denied errors on SendMessage or PostMessage make no sense unless the process sending the message is running at a lower integrity level than the target process.
This should not be happening unless the process that owns the target window is being run "asAdministrator" or is a service. And its damn hard for services to create windows on the interactive desktop with Windows 6 and up.
You can do some reading about Integrity Levels Here if they apply even remotely to this situation. Internet Explorer is about the only other application that 'opts in' to the integrity security model by purposely lowering the integrity level of itself in order to sandbox itself more effectively.
If you can raise the window containing the button you can send raw mouse event to a position within the boundaries of button.
There are two function to simulate mouse event SendInput and mouse_event. I recommend using mouse_event function. To raise a window you can use ShowWindow. I don't know how to get the handle of a button, but if you have its hWnd its easy to find its absolute position using GetWindowRect function. Try using these, if you run into any problems I will be glad to help.
Or define a custom WM within your application window to handle save request. WM_CUSTOM or WM_USER (cant remember which) marks the start of user defined window messages.
When I have to do these kind of things I use SendKeys. It is VB-ish and C# provides a nice interface to use but for C/C++ you'll have to do it <this way>. What is nice with it is that you could write scripts and run them instead of hard coding it in your code.

Sorry I don’t have any simple code to get you started. As “SendMessage()” does not seem to be working for you, I don’t know of another option apart from “UI Automation”
I am assuming you have check with Spy++ (installed with MsDev) that you message are being send to the correct button etc – and that the button is a standard windows buttons. My first instant would say use “SendMessage()" or "PostMessage()” but given the numbers of answers about “SendMessage()” and the fact it is not working for you. I expect someone is going on…
//Send digit 4 to the already opened calc.exe
HWND windowHandle;
windowHandle = FindWindowA(NULL,"Calculator");
if(windowHandle != 0)
ret = EnumChildWindows(windowHandle,GetButtonHandle,0);
BOOL CALLBACK GetButtonHandle(HWND handle, LPARAM)
{
char label[100];
int size = GetWindowTextA(handle,label,sizeof(label));
if(strcmp(label,"4") == 0)
{
PostMessage(handle ,WM_LBUTTONDOWN,(WPARAM)0x0001,0);
PostMessage(handle ,WM_LBUTTONUP,(WPARAM)0x0001,0);
PostMessage(handle ,WM_LBUTTONDOWN,(WPARAM)0x0001,0);
PostMessage(handle ,WM_LBUTTONUP,(WPARAM)0x0001,0);
return false;
}
return true;
}
You can use sendkeys (as tr3 said) to send mouse clicks, which is different than using SendMessage. It is also less direct and more hack-ish, but is useful for automation (in VBS).
Also, just a guess but the problem could be that your message handling is broken somewhere by not calling the base class member. Example:
void CMyClass::OnMessageY(CWnd *cwnd)
{
CBaseClass::OnMessageY(cwnd);
//... my code
}
if you sure ButtonHandle are valid handle you can use pair WM_LBUTTONDOWN and WM_LBUTTONUP message instead of BN_CLICKED
HWND ButtonHandle;
if( (wnd = FindWindow(0, "Do you want to save?")) )
{
SendMessage(ButtonHandle, WM_LBUTTONDOWN, MK_LBUTTON, 0);
SendMessage(ButtonHandle, WM_LBUTTONUP, MK_LBUTTON, 0);
}
A non-C approach: Use Java and the java.awt.Robot class to move the mouse around perform real clicks (I guess there is something in the Windows World for this, too).
Problem: You have to know where your button is :D
