I am executing a Perl file. I am getting this error. Can anybody please suggest the solution. I am getting this kind of error on many pages like:
"Can't call method "goto" on an undefined value at " ..
Means error is same just by replacing get method name.
Please help.
It means the variable on which the method get is called is undefined instead of being an object that accepts the method.
Look at the line number given by the error message (in the file given by the message). If the error is in a module, and you don't see where the variable should have been initialized, then put use diagnostics; at the top of the script after your use strict; and use warnings; so you get a stack of the method/function calls at the point of error.

I use the objSNMP.get method in Excel VBA without any problems.
I'd like to use the objSNMP.set method, but unfortunately it's not that easy. According to the website, it should work similarly to get, with the difference that there is one more parameter: the value to be sent.
If I try the official way:
objSNMP.Set ("43.18.1.1.2", OIDValue)
Image1
I get the message "Compile error: Syntax error".
I found another solution that works conditionally. Namely as follows (it can be seen commented out in the picture):
randomVarName = objSNMP.Set("OID", Value)
For example:
temp = objSNMP.Set(".1.3.6.1.4.1.9.9.68.1.2.2.1.2." & PortNum, 21)
In this case, the code runs without error. This is interesting because I haven't found any official information about this anywhere. Somewhere deep in the recesses of the internet, I only found this possible solution some time ago.
If, on the other hand, I do not enter the value directly, but write the name of a variable there (e.g. VLANNum),
temp = objSNMP.Set(".1.3.6.1.4.1.9.9.68.1.2.2.1.2." & PortNum, VLANNum)
I receive an error message. Image2
It doesn't matter if the type of the variable is not declared, string or integer. I also tried several different cell types in Excel, but nothing changed.
The error message is:
Run-time error '-2147467259 (80004005)':
The requested SNMP operation attempted to modify a variable, but
either a syntax or value error occurred.
Based on the above, I cannot insert the value read from the excel table at the end of the "objSNMP.Set" method in such a way that it can send the value. I could only solve the task if I create 4094 different "objSNMP.Set" lines and select what is necessary from among them. Not very efficient.
I have the solution. The value transferred with the variable works in the following form:
objSNMP.Set ".1.3.6.1.2.1.2.2.1.7.9", CInt(x)
Where x is the variable.
I just created this tiny Office script:
async function main(context: Excel.RequestContext) {
context.workbook.names.getItem("Newname").delete;
}
The range name 'Newname' exists in the current workbook, the code runs without error but the name is not deleted. Why? I would expect to receive a runtime error if I'm not allowed to delete range names.
I think it missed the bracket:
context.workbook.names.getItem("Newname").delete();
I just tried by this gist, you could have a try. https://gist.github.com/lumine2008/f55a6265a93b421112de210b22e9a48a
delete is a method. In JavaScript, a method requires opening and closing parentheses, even if there are no parameters to be passed:
context.workbook.names.getItem("Newname").delete();
My tests confirm this. Also, the code should include await.context.sync();
It's important to realize that JavaScript supports assigning a method to a variable (object), similar to assigning a function to an Excel Name, by leaving off the parentheses. This object can then be used at some point to execute the method. This is why no errors are thrown when the parentheses are omitted.
Example:
const deleteNewName = context.workbook.names.getItem("Newname").delete;
deleteNewName();
(Thanks to Lumpenstein for this information about JS kindly provided in a comment.)
I have a VBA function that worked fine, until I tried to pass an extra variable to it. Now the code won't run, and I get an error stating Expected:=, I've tried renaming the function, but no help.
Was - Function GetData(site_add)
Changed to Function GetData(site_add, temporary) and failed - despite changing the call to the function accordingly...!?!
Is it possible that the compiler is glitching and I should focus on that? I have other functions in the code that use 5 call 5 variables and don't even call/use them all...!? Help...
By adding the second parameter, you are effectively telling the compiler that every call to this method now requires two parameters instead of one. So you have to find everywhere you call the GetData() function and make sure it now passes two parameters instead of one, even if the second parameter is Nothing. Now, if you want it to default to nothing so you don't need to pass it you can rewrite it as
GetData(site_add, Optional temporary)
*my vb is rusty, so take my example with a grain of salt please.
This isn't so much a question to help me figure out code, rather a question asking what the behavior of an object is. In python 3, there is a function
dir([object])
I am reading the python document on it, and it says it returns the names of the arguments attributes, more or less. And if there is no argument, it returns the list of names in the current local scope. So let's say, my only code I have is:
dir([nullObject])
I haven't initialized it at all in my code, so it should just be null. Does the compiler see this as an error, or will it treat the function as if it was called without any arguments?
There is no such thing as a "null object" in Python. There are unbound names, but those result in a NameError as normal.
I need to see the full object returned by node_load() method. I know we can use var_dump() method for this. but don't understand where and how to use the var_dump() method...
Thanks
print the output in a drupal message (I'm using var_export() to redirect the output).
drupal_set_message('<pre>'.var_export($node, true).'</pre>');
Paste these lines on the first line of the function.
