Objects - structures like a Dictionary, Collection, Object, Workbook, and so on - take up a lot more space than simple variables, like an Integer, String, or Boolean. I ran through this thought exercise since it can be helpful in showing why VBA doesn’t always make copies of “variables” when you pass ByVal. You may be wondering what’s the point of talking about memory addresses.
When the program returns to the original subroutine, the VBA program looks to the original memory address (0x0001234), not the copy’s address. In our ByVal example from the previous section, VBA now has two variables with the name myString, but they refer to completely different memory locations. The two different x variables point to different memory locations. You can have copies of variables, or you can have identically-named variables in different subs or functions.Īt the hardware level, that means our example has an x variable stored at 0x0001234 and a variable with the same name, x, at another location, say 0x0006789. However, just because a variable has the name x doesn’t mean it is always referring to the same memory location, even in the same program. If you change the value by writing x = 10 the value stored at 0x0001234 would change to 10. Every time you reference x, your machine accesses memory address 0x0001234. When you initialize a variable using Dim x as Integer a memory location is set aside for a variable of datatype Integer, and its address is stored in a lookup table. If you write a new value to a variable, say by writing x = 2, the value at that memory location is changed. When you call that variable for use in calculations, the machine looks up the memory location and accesses that physical location to retrieve the value. There is a physical place on a RAM chip that stores the value of that variable, which is referenced by a memory location ID (memory address). In a nutshell, that’s what ByVal does.Īll computer programs must store their variables somewhere in working memory (RAM). The string goodbye is actually assigned to a second, short-lived instance of myString, which is erased after sub_sub2 ends. This happens because the instance of myString that is looked up by the Debug.Print line is the original variable. To do this, simply add ByVal in the declaration line of the called sub, like this:Īt the end of this subroutine, myString should output hello. You can shield your original variable by making a copy of it, then passing this copy to the new function/sub instead of passing the original variable. Often you don’t want to modify your original data, but you want to work with that data in another function or sub. Sometimes it can even be dangerous to the integrity of your application. It’s relatively intuitive, but not always useful. The variable myString went to sub_sub, was modified, and came back with a different value. If you run this, you should see goodbye in your Immediate window (press Ctrl + g to display the immediate window). We didn’t specify how we passed the variable, so it defaults to ByRef. In this example we passed the variable myString to the sub_sub subroutine. Print myString End Sub Sub sub_sub ( myString ) myString = "goodbye" End Sub Presently I am doing it manually and want to know if this can be automated using MS Excel or preferably in google sheets.Sub pass_variables_with_defaults () Dim myString As String myString = "hello" sub_sub myString Debug. PS: I have not captured pid (player ids) in the attached excel file) which I should have done it. Kindly have a look at it and let me know if there is a way to do it and if there is worth spending time on it. I am also attaching an excel file on the desired tabular format. (There is a limit to the api key and the link may not open after few hits and therefore I am also attaching output of the link in a text file). Here is a link from where the json data can be fetched. Please let me know if this can be done in MS Excel or google sheets (preferred). This is why I came here to check if it can be done in Excel using vba/macros/formulas.

However the output of CricAPI is standard JSON format so if you have a person who knows how to program Google Sheets they will likely be able to fetch the data you need. You'll need to work with someone who has experience with Google Sheets. I then contacted support team of cricapi but they are not willing to give support for google sheets and sent me the mail given below: I tried working with scripts in google sheets to import the data but it doesn't get imported in a proper format. I was trying to figure out how to get the data in google sheets. delivers an api service where they give out data in json format that can be read through ASP/ASP.NET, PHP, CURL PHP, Node.JS & Javascript for which they have given sample source codes on how to retrieve the data.
