invalid command name in tcl while running my tcl script for new protocol in ns2 it shows error as:
num_nodes is set 108
invalid command name “Agent/HEBM”
while executing
“Agent/HEBM set radius_2”
(file “balance.tcl” line31)
please, reply as soon as possible, it will be very helpful to implement my project.
It is because tkinter window closed but other processes related to it are still running. To avoid this, put try and except wherever the error is occurring in your code. To avoid the error, do this whenever the error function is called:
import sys
...
try: the_function()
except: sys.exit(1)
Fell free to comment in case of more detail requirement or any error if occurred.

I use cocos2d-x to do the game. After running my program for a while, the variable "NotEnemy" will always report the "access violation" error. NotEnemy is the variable I set in EventListenerPhysicsContact, always using cocos2d-x There will be errors like the title, all I want to know when there is such a mistake, is there any solution, I hope someone can tell me, right, NotEnemy I am assigned this way, auto NotEnemy=contact.getShapeB( )->getBody()->getNode();
I tried setting it to nullptr after using NotEnemy, but it didn't work. Now it generates a new error "Exception at 0x76EE35D2 (located in TankBattle.exe): Microsoft C++ Exception: std::exception, in memory Location 0x00C5F548.
There is an unhandled exception at 0x7640E6EB (ucrtbase.dll) (in TankBattle.exe): A critical program exit has been requested. ", used to be an error about access permissions conflicts, but they are all problems with NotEnemy, and they all appear in the "NotEnemy->SetPosition(Vec2(166,14))" statement.
filename and line number of python script
I need to print the current filename, function and line number in a Cython script. The proposed solutions only work for .py script and they do NOT work for Cython script.
Thank you
This is a pretty unsatisfactory work-round, but I suspect it's probably (close to) the best you can do.
Cython generates debugging info when an exception is raised, therefore you need to raise and catch and exception to get access to this info
import sys
import traceback
def f():
# code ...
try:
raise RuntimeError() # get information about this line
except RuntimeError:
print(traceback.extract_tb(sys.exc_info()[2],limit=1))
# ... more code
Note that you can't attempt to save duplication by putting this all in a "get_debug_info" function and then looking further up the stack trace - Cython only generates the stack frame for a function as the exception propagates up the stack so if you catch the exception then you can't see any Cython frames above it.
I'm working on a project and I become always an Exception "TypeInitializationException".
I tried to give a string to a global string variable but it failed.
That's the code for the viewmodel and it failed on the second line
| {State = _}, ConsumablesClicked vm ->
Testtyp <- vm.TrackPosition.ToString()
That's on the other program
let mutable Testtyp = ""
I become this InnerException "Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read.".
"The type initializer for '.$BarcodeGenerieren' threw an exception.", that's the exception explication.
Has someone a Idea how solve this?
That exception indicates that some code is trying to call Console.ReadKey when the standard input for that process has been redirected (see e.g. Allowing redirection of StandardInput of a C# application when doing "Console.ReadKey"). The solution is not to call Console.ReadKey, but it's not clear from your description where this is actually happening (perhaps in the static constructor for one of your types?).
I found the solution after a lot of try and it was only, that I had a Console.Readkey in my code, that I forgot to delete.
I had before a console apllication and I transformed it to be a class.
using EF4
I atempt to make a connection but get this error message
"Entity Exception Message At least one of the input paths is not valid because either it is too long or it has incorrect format."
This used the example from http://msdn.microsoft.com/en-us/library/bb738533.aspx but passing in my own server name. What is the "input paths"
When I run it from a web app its fine, when I try and run it in a unit/integration test passing in the connection (as app.config might not be there) I get this error.
Whats going on?
I had the same issue. I was writing the code in the following way
ebuilder.Metadata = #"Model1.csdl, Model1.ssdl,Model1.msl";
Then after some research I changes it to
ebuilder.Metadata = #"res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl";
The magic happened and it started working.
I had same error in EF6. when I try to fetch something from DB, this error was thrown.
I solved this problem with correcting the MetaData part of my connectinString.
you must have MetaData part like below:
metadata=res:///myModel.csdl|res:///myModel.ssdl|res://*/myModel.msl;
Having a StorageFolder object and trying to create a folder with a name that contains a colon somewhere inside (not at the beginning or the end) results in a COM error with HRESULT 80004005 (HRESULT E_FAIL).
Example:
await ApplicationData.Current.TemporaryFolder.CreateFolderAsync("abc:xyz",
CreationCollisionOption.OpenIfExists);
If the colon is at the beginning ot at the end I get a HRESULT 8007007b with the message "The filename, directory name, or volume label syntax is incorrect". That's fine.
I checked with other invalid chars but only a colon leads to E_FAIL.
This may be a problem if the user enters the folder name. Workaround is of course to simply check for a colon in the filename.
Does anyone know a possible reason for the E_FAIL error? I assume that COM thinks the foldername starts with an URI but can of course not figure out what kind of URI it is.
Well, COM's infamous error reporting is back with a vengeance. We've gotten spoiled from years of .NET's excellent and informative exceptions but that rug got pulled by WinRT. COM is the underlying interop mechanism and HRESULTs are the way errors get reported.
E_FAIL is the canonical error code, the only descriptive text you can get with that is "Unspecified error". Which is accurate, the Microsoft programmer that handled that code could not or did not want to produce a more descriptive error. Another great doozy is E_UNEXPECTED, it translates to "Catastrophic failure". The term "catastrophic" really refers to the value of the error message if you ever get it.
Speculating somewhat, the "abc:xyz" path string is actually valid. It refers to an alternate data stream named "xyz", stored in file "abc". So checking the path string isn't going to raise a stink, at first. You are however creating a folder by that name, not a file. A folder cannot have an alternate data stream. Apparently this is discovered very late, too late to still produce a more accurate error code. It should have produced a Windows error and they are wrapped appropriately in a HRESULT by or-ing it with 0x8007000 but that wasn't done for unguessable reasons.
No way to send feedback about this, the Windows group doesn't have the equivalent of DevDiv's connect.microsoft.com. Good thing you know what caused the error.
