#WINRUNNER VIDEO TUTORIALS SOFTWARE#
In Sept 2016, Hewlett Packard Enterprise announced it is selling its software business, including Mercury products, to Micro Focus. Hewlett Packard Enterprise acquired LoadRunner as part of its acquisition of Mercury Interactive in November 2006. LoadRunner can generate the scripts by recording them, such as logging HTTP requests between a client web browser and an application's web server. The messages and interactions to be generated are stored in scripts. LoadRunner simulates user activity by generating messages between application components or by simulating interactions with the user interface such as keypresses or mouse movements. LoadRunner can simulate thousands of users concurrently using application software, recording and later analyzing the performance of key components of the application. It is used to test applications, measuring system behaviour and performance under load.
LoadRunner is a software testing tool from Micro Focus. But for out parameters there is no use to send value.Simplified Chinese, Dutch, English, French, German, Italian, Japanese, Korean, Portuguese-Brazilian, Russian, Spanish. So, by this we came to know while working on ref parameter we need to send value too. Let me show the drawback of “ref” parameter as shown below code.Įrror 1 Use of unassigned local variable 'i' Let’s try this using “ref” in the function. Same as above, But as I told you we are getting an error when I am trying to use “I” in the “Calc” method like “i=i+2000”. Let’s change “out” to “ref” in the above program. Address into the formal parameters, In the reference type parameters formal parameters modifications effects in the actual parameters, As per C#.Net we can get the variable address, we can send the variable address. Using reference type parameters we can send actual parameters. To retrieve this particular requirement Microsoft introduced Reference type parameters. It will through you an error (unassigned).
#WINRUNNER VIDEO TUTORIALS CODE#
But in the previous code I am trying to display in Calc method and that through an error because when you mention “out” in the method parameters then it won’t take “in”. Hence the variable “i” changed to 2000 Great. We need to mention “abc.Calc(out i) ” to retrieve by this error as shown below code and with little modification. But here we forgot put “out” keyword in calling function “abc.Calc(i) ” so its throwing error. This “out” keyword indicates what ever the changes made to “i” in “Calc” function that should return to Main(). I just added a “out” keyword in “Calc” function. The above code is same as our previous one.
Here below code explains you first program using out parameter with error.Įrror 1 The best overloaded method match for '(out int)' has some invalid argumentsĮrror 2 Argument '1' must be passed with the 'out' keywordĮrror 3 Use of unassigned out parameter 'i' So to retrieve this requirement microsoft introduce this concepts. By this example if we change the variable name in the method “Calc” it wont effect the variable in Main() method. Here i am sending value 100 when I call “Calc” method from Main() and display the value inside the “Calc” method.Īgain while going back to Main() i assigned a value to “i=2000” and then WriteLine will display the value 1000 again. So using “abc” object we are calling “Calc” method with one parameter. Variable “i” is initialized to a value 100. Here “abc” is an object that looks like “Number” class created. First I will show you a code which includes a class and view variables.Ĭonsole.Write("Press any key to continue.") It’s very hard to get understand the above sentence let me explain you with example. The Microsoft newly introduced out parameters in the c#.net, Using out Parameters we can send formal parameter value into the Actual parameter, while working with the out type parameters we have to initialize values to the formal parameters, out type parameters function can returns collection of values.
