Pass the parameter to the functions called from a dll

Hi all

I am interfacing a motor controller for PMC - 100 through the Protocol of Performax using labwindows.

I need to explicitly link the PerformaxCom.dll and call functions with him. I'm calling this function

BOOL fnPerformaxComOpen (DWORD IN dwDeviceNum, OUT HANDLE * pHandle);

Faithful:

If you want to link explicitly, you can consult this article: http://zone.ni.com/devzone/cda/tut/p/id/8503

It has a code snippet that shows passing two parameters to a DLL function.

But as for your statement that "I don't know how to pass parameter to him", in the example, you reference, you pass a parameter: it's just a constant string rather than a variable.

  • Pass a parameter to a function to use AS the operator in

    I'm trying to pass a parameter to a function that uses the LIKE '% name_in % ',.
    I don't know how to use...

    the setting is called "name_in".


    Thanks in advance,

    the setting is called "name_in".

    Your code should say:

    ... LIKE '%' || name_in || '%'
    

    If name_in is inside the single quotes, it will mean the 7 characters literals 'n', 'a', ', 'e', '_', 'i' and 'n'.
    You want to refer to the variable named name_id, in order to keep the name of the variable outside of the quotation marks.

  • I know where the last call from my iphone stolen?

    I know where the last call from my iphone stolen?

    Not anyone here, not Apple. You can check with your operator if they used your SIM card, and you may have to get the police involved for the information about the location. If it was not your SIM card, you would not be able to.

  • The missed calls from deleted blackBerry Smartphones the next day

    Hello

    With my Blackberry Curve if I miss a call he's going in the call log; However, the next day, all the missed calls from the previous day are deleted.  I checked and it is not a memory problem.  Is it possible to record missed calls, so that they are not automatically removed?

    Thank you!

    No, your call log will always show the last 20 calls.

    The shortcut would be to open the list of Messages, press ALT + P.

  • Call the function QML from C++ (simple question)

    I guess that's a pretty easy question but I'm a bit new apart from development c ++ of BB10. I have a QML file in the assets folder called Functions.qml which has only onne inside functions.

    import bb.cascades 1.3
    
    Page {
        objectName: "funct"
        function printStat() {
            console.log("hello");
        }
    }
    

    In one of the functions in applicationui.cpp there is a function called resendNotification() (you may know this code from the model of the app without head)

    void ApplicationUI::resendNotification()
    {
        InvokeRequest request;
        request.setTarget("com.example.TestNotificationService");
        request.setAction("com.example.TestNotificationService.RESET");
        m_invokeManager->invoke(request);    // --> call the printStat() function of Functions.qml file
        Application::instance()->minimize();
    }
    

    My question is, before you minimize the app How can I call the function printStat() of the qml file? I have always developed my apps in QML so never had to deal with c ++. Should be easy enough to call a function well.

    Thank you in advance!

    first step is to find the object by ObjectName using findChild, usually from your element root (navigationPane).
    example:
    NAV-> findChild ("myTextField")

    If you have the object of another source that is fine too, of course.

    second step is to use QMetaObject::invokeMethod with the object and the name of the method.
    Example:
    QMetaObject::invokeMethod (container, "setText", Q_ARG (QVariant, text));

  • The function parameters from a non sequential fashon

    Consider the function below:

    personalfunction (String Name, int age, City: String): void
    {
    trace (name + "is" + age + "years old and lives in" + City + ".")
    }

    The settings can only (?) be passed in the order they are declared in the function, as shown below.

    personal ('John', 40, "London", 0)

    If the order is changed like: personal("London" ", John", 40), there will obviously be a type error (position 2 parameter is an integer).

    Is it possible to pass parameters to the function as: personal(city = 'London', name = John", age = 40)?

    In this way, we don't have to worry about 'order' in which parameters are passed.

    You can use:

    obj instanceof. Age number

    obj. Name instanceof String

  • Retrieve the name of the function call

    I have 2 function in the CFC, even calling another function in the same CFC.

    IS anyway to get the name of the first function (the appellants) from the second?
    OR
    is there anyway inside a function to retrieve this name?

    Sounds right up your alley:

  • Received the phone call from support, is this a scam?

    Just got a "phone call from an Indian call center, arguing that my PC send malicious messages. They wanted me to run a Prefetch. I pretended that I he had just had a power cut and could not operate my computer. After asking SEVEN times how he got my ' phone he hung up.

    Just got a "phone call from an Indian call center, arguing that my PC send malicious messages. They wanted me to run a Prefetch. I pretended that I he had just had a power cut and could not operate my computer. After asking SEVEN times how he got my ' phone he hung up.

    I had 4 phone calls during the month. The first, I was late for an appointment, and I had to go. Fortunately, I had time to think and realized it was a scam... Be caught unawares gives them the advantage

    The second, I knew it was a scam. I listened and then never said thank you and hung up.

    During the 4th, I was ready for a little fun. First of all, I unplugged the ethernet from the modem, just to be doubley sure.

    He guided me through his wicked manouevers, and every time I lied I did. When it asked me to press the Microsoft icon to the right of the Ctrl key and 1, I said "I have an Apple on this key". He said 'you have a Mac. I said: 'no, I have Windows to the top. Microsoft icon beside the right Ctrl key. I can get my Mac computer to Windows with these keys. "He said"I'm confused"I answered:"have you not heard of the latest technology. It's called the computer Jekyll and Mr Hyde' at this stage that he hung up.

    The longer you keep him talking, the greatest of his phone bill will be and it loses time to scam someone else.

  • Is the phone call from someone with Microsoft real?

    received a phone call from someone who said 'they were Windows and one person was haking the computer/laptop from my house', I would like to know if this is true and how to fix it?

    * original title - Haking *.

    It is certainly not true.  Microsoft does not contact customers unless they contacted Microsoft first and asked to be contacted.  It is a scam, just hang on them if they remember.

  • Is there a way to discover the function calling ESTK?

    Dear forum,

    How do you find the calling feature?

    I remember this issue has been asked on the forum before and, if my memory is good, it's Peter Kahrel who did it. Anyway, it was a long time ago and I can't find the post.

    main();
    function main() {
        hello();
    }
    function hello() {
        // Is it possible to find out that the caller function is 'main'?
    }
    
    

    Before taking the post, I googled for it and find many suggestions, for example:

    alert("caller is " + arguments.callee.caller.toString());
    
    

    But nothing works for me.

    Kind regards
    Kasyan

    Here is a new version of the function:

    function callerName() {
        var arr = $.stack.split(/[\n]/),
        callerName = arr[arr.length - 3].replace(/\(.*\)/, "")
        return callerName;
    }
    

    I fixed the regular expression to remove the brackets and everything.

    The previous version returns the name of the function with arguments, as follows:

    Result: ProcessTables ([paragraph: [object paragraph]])

  • How to make/receive the phone call from a laptop connected to the smartphone via bluetooth?

    Dear community of Microsoft,

    I have a smartphone (Samsung SCH-I759) which I want to connect to a laptop running Windows 7 Professional, then I could make/receive the phone call on the cell phone.

    After browse around, I saw several methods to do are pretty simple. Activate bluetooth on both devices connect, match and set - the bluetooth device menu.

    When I followed these instructions, I was able to pair the devices but the ability to use the bluetooth connected as a phone smartphone does not appear. Instead, I have less accessible services in the menu. Here is the screenshot:

    For those who have been successfully pair and use their laptops as phone, would you care to share the how-to?

    Thank you

    NALA Jati

    It depends on the abilities programmed into your phone. Your photo, I can say that is not possible on your phone, then you will not be able to do.

    If you want to make/receive calls on your computer, you could try to use Skype or Google Voice.

  • Received the phone call from scam of asking to connect to the computer

    A man with a voice of Indian call center called and asked my friend to connect to his computer because they knew that she had had problems with the help and he called for a "windows service center.  She asked for a number to call back and he hung up.  There is a phishing scam rightnow?

    It is a phishing attempt! Do not give any information.

    Reported people on these calls for a person who represents Windows (note: not Microsoft).

    It is a scam! Not to follow their instructions or advice and not to provide ANY information to them.

    Because they use the internet lines and/or phone to complete their fraud, there may be federal agencies in your country who are interested in discovering their calls. Their report directly to the appropriate agency if you feel you can contribute to their arrest and the charges.

    Microsoft do NOT pick up the phone and start dialing customers and never phones/e-mails asking for personal information or asking them to visit a web site!

  • Received the phone call from 'Computer Maintenance of Windows operating system', is it a scam?

    Original title: scam or not

    I just got the phone is off "Windows OS computer maintenance required", I went through the senario execution because I apparently files may contain a virus.  I got a number to call back and ask for Henry 02 80060075 apparently in Sydney.  I remembered and has a call center responded in the form of windows.  After going through several id checks which they knew my CLSID number but one of them that I take now is the same number for many people.  In any case I tell them I work for a COMPUTER company and would take my computer to work with them check.  The guy said that he did not believe I worked for a COMPUTER company, because I did not understand what they are trying to help me for a very small cost of AUD $110.  After a long debate and tell him, I thought it was a scam I hung up.

    So my question is: Windows to call Manila on a Saturday night at 5:30?

    It is a popular scam. Microsoft has no unsolicited phone calls. You should read the very first post on this forum.
