Hello
I used this code to add printer but it did not work
try
{
oManagementScope = new ManagementScope(ManagementPath.DefaultPath);
oManagementScope.Connect();
ManagementClass oPrinterClass = new ManagementClass
(new ManagementPath("Win32_Printer"), null);
ManagementBaseObject oInputParameters =
oPrinterClass.GetMethodParameters("AddPrinterConnection");
oInputParameters.SetPropertyValue("Name", "testprinter");
oPrinterClass.InvokeMethod("AddPrinterConnection", oInputParameters, null);
return true;
}
catch (Exception ex)
{
return false;
}

What does "it didn't work" mean?
Where did you specify what printer to connect to? What driver to use? What printer settings (port, ip, etc)? I can't imagine you would get a working printer just by telling Windows the name of one...

Thanks for answer
did not work mean when I execute the code and go to Printers ,I did not see any new printer.
I want to create it on local host(Client Machine)
Port:Local port.
IP:Local IP
thanks

No problem.
There are only 10 types of people in the world, those who understand binary and those who don't.

The same way you would do it on paper. Create a List of all the points in the graph and then draw a line from the first to the last, passing through each intermediate point. You can do this by using the Graphics Class[^], or search Google for some other utility classes that may help you.

I do not plot as in the picture. No numbers only lines

|
Sorry, but I do not know what you mean.

No lines. does not seem spots

Sorry, but that is no more clear. Try explaining in detail what you are having trouble with. And if it is a matter of translation, then perhaps you can get someone else to help with the English.

self.dots=[]
for i in range(0,num_dots)
if (condition)
self.dots.append("fix",dots[i])
else
self.dots.append("free",dots[i])
Hi all.I have a part of my project created in python and i would like to rewrite in c#.In python i used a list (self.dots) to have every item ordered with its string value.in c# i don't know how to obtain the same thing.i need to check if each item is free or fix but following the order i previously established.

Perfect.thank you very much

Take a look at the SortedList[^] or SortedDictionary[^] classes.
other than that there is also a "Sort" Method on the Default List[^] object. Where you can pass a comparer object with your logic how to sort the items contained in that list.
Besides, I'm not really sure what you're trying to accomplish. So I can't guarantee those are what you're looking for

Ok.thank you very much.Do you know how the sorteddictionary is ordered? by adding elements?i am looking up on the web in the meanwhile.
|
|
|
|
|
In the SortedDictionary sorting is made on the key. And you can't have the same key multiple times in the same dictionary.
Note that for both the SortedDictionary and the SortedList the object on which the sorting should happen has to implement the IComparable Interface or you need to assign an IComparer Implementation that takes care of the sorting for you.

ok i think i have undestood.I only need how to get value by index.is the following the only way?and do you think is it too slow?
sortedDictionary[sortedDictionary.ElementAt(index).Key] = value;
thank you very much
|
|
|
|
|
If you want to use the dictionary this should suffice. But that's just from the top of my head:
sortedDictionary.ElementAt(index).Value = value;
There should be no need to access the dictionary twice just to set the value.
|
|
|
|
|
|
If you wan't to use the index instead of the key take another look at the SortedList.
There is an example of how to access an element by the index (Hint: myList.GetByIndex(i))
There are places where a Dictionary is useful and then there are places where List is useful. That's why both those types exist.
|
|
|
|
|
ok thank you very much. now i will try both to understand which is the best solution for me
|
|
|
|
|
i didn't know SortedDictionary<tkey, tvalue="">.I'm searching for information in internet.Is it the right way?
Thank you

Whether a SortedDictionary, or a SortedList, is "right," depends on the requirements of your code.
Does the solution you are creating require frequent immediate access to a sorted collection of data, and is that data "coming in" in a way where it's "unsorted" ?
If that's the scenario, then perhaps you are required to sort the data every time you add a new item to it.
On the other hand, if your need for access to sorted data is intermittent, perhaps you'll get better performance if you sort on demand.
Keep in mind that a SortedList is a collection of Key/Value Pairs, and there is a cost in memory, and computation, for maintaining it compared to a simple Generic List, just as there is for using a SortedDictionary.
“I'm an artist: it's self evident that word implies looking for something all the time without ever finding it in full. It is the opposite of saying : 'I know all about it. I've already found it.'
As far as I'm concerned, the word means: 'I am looking. I am hunting for it. I am deeply involved.'”
