I'm trying to create a Selenium script in Powershell that automatically buys something that I tell it to. I've gotten it past finding the item, and clicking the Buy Now button, but then this window pops up and I've tried what seems like 3000 different ways of failing to click the Place your order button. Web code to the right. Appears to be the "turbo-checkout-pyo-button", but finding it by ID, XPath, CSSselector, etc have all failed for me. It's not a wait issue. I've even thrown in an explicit (and overly long) 5 second delay to be sure this field is present and "should" be clickable. Any ideas?
I've tried all of these. They're all followed by $placeYourOrderBtn.click() (and have all failed):
$placeYourOrderBtn = $ChromeDriver.FindElementByXpath("//*[#id='turbo-checkout-pyo-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//*[#id='turbo-checkout-place-order-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//span[text() = Place your order]")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-place-order-button-announce")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-pyo-button")
$placeYourOrderBtn = $ChromeDriver.FindElementByCssSelector("#turbo-checkout-pyo-button")
I did this for a windows that sends email. You have to click the button to open the new window, then use "SwitchTo()" to change to the new window.
[void]$Webdriver.SwitchTo().Window($WebDriver.WindowHandles[1])
You may have to read the window handles attribute and query each one to determine which one you need to open.
I am working with this example from MathWorks: https://www.mathworks.com/help/supportpkg/plutoradio/examples/qpsk-transmitter-with-adalm-pluto-radio-1.html
When i run the example it creates an sdrqpsktx variable in the matlab workspace
I want to change sdrqpsktx.MessageBits to something smaller.
When i run the following code in matlab:
a = sdrqpsktx.MessageBits(1:448);
sdrqpsktx.MessageBits = a;
I successfully change sdrqpsktx.MessageBits to a.
However when i run this in simulink sdrqpsktx.MessageBits changes back to its original size.
How do i permanently change sdrqpsktx.MessageBits and run the example with my changes?
Thank you.
There is a model callback, probably a StartFcn, that is overwriting your changes to the variable every time you start the simulation. You either need to delete or modify that code.
To see the code go to:
File->Model Properties->Model Properties, and select the Callback tab.
Any callback that is followed by a * has code in it. Click on that callback to see the code.
See Callbacks for Customized Models for more detailed information.
I'm considering using Matlab Compiler to distribute software for a price. I'm investigating (very) simple methods to discourage re-distribution without annoying users. Any recommendations?
One thought is to email a user a license key and have them input this during the installation process to be verified on a license server. If the key matches what is on the server, the installation proceeds as usual, otherwise, a warning message is shown to inform the user to purchase another license. However, this method requires a specified function to run only during the installation process, and not thereafter (so as not to annoy the user). Is this possible using Matlab Compiler or otherwise?
I suppose I could create a file on the user's disk that the program looks for when it starts (if it exists, then it is not being run for the first time), but if the user copies the whole directory, that file would get copied too.
In order to create an effective licensing system, you have to link it to one or more properties of a user machine (MAC address, OS ID, hard disk serial numbers, CPU serial numbers, etc...).
If you don't to this, you are just going to release licenses that can be transferred from one user to another. If one user decides to spread his license file worldwide, you are doomed because everyone could potentially take that license file and use it to unlock your application.
But if you link your license files to one or more properties of a user machine, as mentioned above, you must be able to obtain these properties either:
before the user decides to buy your application;
when the user activates his license.
First Scenario
You release your software as a trial. When it is started for the first time, you set an expiration date in the registry or in a file well hidden somewhere. You check against the expiration date when the application starts and, once it is reached, you throw an error and you don't let the used play with your application anymore.
Within the application, you create a Register Now button somewhere. When it is clicked, the application retrieves the machine properties and passes them to the web page / form that will be opened to let the user perform the payment. That page will be in charge to validate the machine properties, receive the payment and, finally, deliver a valid license code based on these properties.
Within the application, you must implement the same logics that allowed your form to create the license code, because you will need to use them in order to validate the code itself every time your application starts. A pseudo-code example:
mp1 = GetMachineProperty1();
mp2 = GetMachineProperty2();
mp3 = GetMachineProperty3();
lc = GetLicenseCode();
if (~strcmp(sha1([mp1 mp2 mp3]),lc))
errordlg('Invalid license code!');
return;
end
This is the simplest path. But keep in mind that if one or more properties of the user machine change (because he changes a device or reinstalls his OS), his license will be invalidated and you will have to provide a customer assistance service that takes care of this kind of situations.
Second Scenario
This one is much harder. You will not be able to know the user's machine properties in advance. So your licensing system will work on a two-steps basis. You release a unique code (called LID for example) when the used purchases your application. Then, once the user inserts that it in your application, your application must send it back together with the machine properties. The final key (called LKey for example) is then computed and sent back to the user.
mp1 = GetMachineProperty1();
mp2 = GetMachineProperty2();
mp3 = GetMachineProperty3();
lkey = GetLicenseKey();
if (~strcmp(sha1([mp1 mp2 mp3]),lkey))
errordlg('Invalid license code!');
return;
end
Machine Properties
The first solution has been provided to you through a comment: the MachineGuid value located in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography. It's pretty solid. But it will only work on Windows machines. Use winqueryreg to access the registry.
Another good alternative is the Window Domain Controller Security ID, which is another machine-specific unique identifier. You can retrieve it using Java code within Matlab:
wdc_sid = com.sun.security.auth.module.NTSystem.getDomainSID();
or through the Windows registry key HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\GroupMembership. The registry approach should be the one to use if you want to maintain a certain backward compatibility with old Matlab releases. Unfortunately, the Window Domain Controller Security ID is another identifier that is available only on machines that run under Windows.
If you want to adapt your licensing system to every possible OS and environment, you have to use a more generic approach, based on universally accessible hardware properties: MAC adresses, hard disk serials and such things. As far as I know, the most reliable property is the MAC address, because its uniqueness, althrough not granted, is almost certain and it's very unfrequent to change a network adapter (there are more chances to break an hard disk actually). Retrieve the MAC adresses of the machine network adapters using Java code as follows:
mac_addrs = '';
net_int = java.net.NetworkInterface.getNetworkInterfaces();
while (net_int.hasMoreElements)
mac_addr = net_int.nextElement.getHardwareAddress();
if (~isempty(mac_addr))
mac_addrs = [mac_addrs, '-', sprintf('%.2X',typecast(mac_addr,'uint8'))];
end
end
mac_addrs = mac_addrs(2:end);
The above computation produces a character array that represents the result of the concatenation of all the MAC addresses found on the machine. Again, for compatibility reasons, this may not work on old Matlab releases, so you have to use a much more complex approach, described here.
[EDIT]
This approach to retrieve the MAC address based on the underlying OS could be easier:
switch computer('arch')
case {'maci','maci64'}
[~,a]=system('ifconfig');
c=strfind(a,'en0');if ~isempty(c),a=a(c:end);end
c=strfind(a,'en1');if ~isempty(c),a=a(1:c-1);end
% find the mac address
b=strfind(a,'ether');
mac_add=a(1,b(1)+6:b(1)+22);
case {'win32','win64'}
[~,a]=system('getmac');b=strfind(a,'=');
mac_add=a(b(end)+1:b(end)+19);
case {'glnx86','glnxa64'}
[~,a]=system('ifconfig');b=strfind(a,'Ether');
mac_add=a(1,b(1)+17:b(1)+33);
otherwise,mac_add=[];
end
I found it in the comments of this article.
This is probably simple, but I have not found how to do it.
Needing to monitor my C# console application in vs 2015.
The help file for dbMonitor states:
"You can do it by dropping MySqlMonitor on form from toolbox or by creating it manually in code."
But I cannot find out how to create it manually in code.
I am using the PostgreSQL dot connect.
When I run dbMonitor it does not see my processes.

I don't know how I missed it:
PgSqlMonitor pgMonitor = new PgSqlMonitor();
pgMonitor.IsActive = true;
OK, I have been at this for a while ...
I am trying to track when user changes input languages from Language Bar.
I have a Text Service DLL - modeled from MSDN and WinSDK samples - that registers fine, and I can use the interfaces ITfActiveLanguageProfileNotifySink & ITfLanguageProfileNotifySink and see those events just fine.
I also have finally realized that when I change languages these events occur for the application/process that currently has focus.
What I need to do is to simply have these events able to callback to my own application, when it has the focus. I know I am missing something.
Any help here is appreciated.
Thanks.
I did some double-checking, and you should be able to create a thread manager object without implementing ITextStoreACP so long as you don't call ITfThreadMgr::Activate.
So, the code should look like:
HRESULT hr = CoInitialize(NULL);
if (SUCCEEDED(hr))
{
ITfThreadMgr* pThreadMgr(NULL);
hr = CoCreateInstance(CLSID_TF_ThreadMgr, NULL, CLSCTX_INPROC_SERVER, IID_ITfThreadMgr, (LPVOID*) &pThreadMgr);
if (SUCCEEDED(hr))
{
ITfSource *pSource;
hr = pThreadMgr->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
hr = pSource->AdviseSink(IID_ITfActiveLanguageProfileNotifySink,
(ITfActiveLanguageProfileNotifySink*)this,
&m_dwCookie);
pSource->Release();
}
}
}
Alternatively, you can use ITfLanguageProfileNotifySink - this interface is driven from the ItfInputProcessorProfiles object instead of ItfThreadMgr. There's a sample of how to set it up on the MSDN page for ItfLanguageProfileNotifySink.
For both objects, you need to keep the source object (ITfThreadMgr or ITfInputProcessorProfiles) as well as the sink object (what you implement) alive until your application exits.
Before your application exits, you need to remove the sink from the source object using ITfSource::UnadviseSink, and then release the source object (using Release). (You don't need to keep the ItfSource interface alive for the life of your application, though.)
