[RESOLVED] Getting error : Round is not declared ….

The following code generate error: Round is not declared ….

Private Sub Command1_Click()
Dim dNum As Double
dNum = 95.33266545
Text1.Text =

Round(dNum, 2) & «%»
End Sub

How to modify it?

Thanks.

Re: Getting error : Round is not declared ….

check menu > project > references
look for any missing references and remedy

i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next

dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part

come back and mark your original post as resolved if your problem is fixed

Re: Getting error : Round is not declared ….
Perhaps you’ve overloaded the global definition somewhere by declaring something as Round elsewhere in your program. You can work around this by using VBA.Round to resolve the ambiguity you introduced.

However since you’re only trying to create a String expression anyway (relying on implicit type coercion, not the best policy when programming) why not use one of the many functions for doing this?

If you had a proper fractional value you could just use FormatPercent$, but for some reason you’ve already prescaled your value by 100. You can also use Format$ once again being clever in order to un-do your prescaling.

For example:
Code:

Dim dNum As Double dNum = 0.9533266545 'No prescaling! Text1.Text = FormatPercent$(dNum, 2) & "%"
Or:
Code:

Dim dNum As Double dNum = 0.9533266545 'No prescaling! Text1.Text = Format$(dNum, "0.00%")
Or in your case you have to unravel your prescaling:
Code:

Dim dNum As Double dNum = 95.33266545 Text1.Text = Format$(dNum, "0.00%")

Re: Getting error : Round is not declared ….

I am sorry. Actually I am using it on vb.net. It is working fine on vb6. What can I do now? Shall I post this question on vb.net?

Thanks.

Ahh. Yes, asking in a VB.Net forum might get you faster answers.

«___ was not declared in this scope» err

«___ was not declared in this scope» errors

I am receiving compiler errors as follows and do not know how to fix this. I know it’s the same type of error, I just don’t exactly know how to fix this error. Thanks in advanced!

main.cpp: In function ‘int main()’:
main.cpp:26:18: error: ‘count’ was not declared in this scope
for (count = 1; count <= 12; count ++);
^
main.cpp:28:13: error: ‘count’ was not declared in this scope
count = count + 1;
^
main.cpp:29:13: error: ‘output’ was not declared in this scope
output count;
^

#include <iostream>
#include <cstdlib>
#include <string>
    using namespace std;
    int main()
    {
            int acctNum;
            string firstName;
            string lastName;
            int purchasePrice;
            int payment;
           
            
            cout << "Please enter account number";
            cin >> acctNum;
            cout << "Please enter customer's first name";
            cin >> firstName;
            cout << "Please enter purchase price";
            cin >> purchasePrice;
            
            payment = purchasePrice / 12;
            cout << "Customer first name:" << firstName <<endl;
            cout << "Customer last name:" << lastName <<endl;
            cout << "Account number:" << acctNum <<endl;
            
            for (count = 1; count <= 12; count ++);
            cout << "Payment number";
            count = count + 1;
            output count;
    }

You’re getting that error because you hadn’t initialized the ‘count’ variable. Write
int count; after int payment;

Also replace output count with cout<<count;
cout is used for console output. There’s nothing called output in STL of C++

Also:
can you explain what you’re trying to do with this block:

            for (count = 1; count <= 12; count ++);
            cout << "Payment number";
            count = count + 1;
            output count;

Hello bkatic,

In addition to what Nwb has said you should give this a read http://www.cplusplus.com/doc/tutorial/control/#for

After yo will notice that for loops are generally written as:

for (int count = 1; count <= 12; count++)
{
    // <--- your code here.
}

The «int» allows you to define the variable count for use as a local variable in the for loop.

To what you think is in the for loop. Actually nothing because of the semicolon at the end of line 27 that should not be there. What it does is limit the for loop to just that line.

This is what your code looks line in a different way:

for (count = 1; count <= 12; count++);

cout << "Payment number";
	
count = count + 1;
	
output count;

I think this is what you intended:

for (int count = 1; count <= 12; count++)
{
	cout << "Payment number";

	count = count + 1;

	output count;
}

What is the point of line 5 in the above code? Between this and the for loop you are adding 2 to count on each iteration of the loop. Adding to count is what the third part of the for condition is for.

Hope that helps,

Andy

Wow, thank you for the responses! I finally got it to work. As to what I’m trying to do with the

for (count = 1; count <=12; count ++)
cout << "Payment number";
count = count + 1;
cout << count;

is from the pseudocode my homework assignment gave me. The pseudocode is as follows:

for count 1 to 12
output «Payment Number», count, «: $» , payment.
endfor

For context the assignment is designing an application that accept’s a client’s loan amount and monthly payment amount and outputs the loan balance each month until the loan is paid off.

But after further inspection and your feedback I understand why it doesn’t make sense and I have to switch things around. Thank you again!

So you’re supposed to display
"Payment Number" count ": $" payment
for 12 purchases

( In your for loop you need to add braces like Andy said, but also you don’t need count = count + 1 because count++ in the for parameter does that job for you. You must have been confused with while )

But where will you get the ‘payment’ from? Something is missing because the program accepts only 1 purchase but is asked to display 12 purchases??

Also I didn’t get why «payment = purchasePrice / 12;» is being done.
And I suspect that purchasePrice is supposed to be an array. Also lastName was never assigned, you can’t call it when it’s not assigned.
