SendKeys.Send("^v")

Hi all

I'm having trouble with my app and i need some help.
I have an app that needs to paste some numbers from a listbox into another App.
Using

SendKeys.Send("^v");

works great while working on a local computer, the problem is that i'm working on a remote desktop and sometimes when sending the "^v" it only sends the "v" D'Oh! | :doh:

Can anyone help me figure this out ?

Thanks in advance. Smile | :)

i take it your ^ represent control?

As per the docs it should be wrapped in a brace; {^}

http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys(v=vs.71).aspx[^]

"The plus sign (+), caret (^), percent sign (%), tilde (~), and parentheses () have special meanings to SendKeys. To specify one of these characters, enclose it within braces ({})"

I don't think that's the problem , because it works without the {} , but for example when i have 50 numbers in the listbox, pasting 45-47 number is OK, while it makes 3-5 random mistakes, sending only the "v".

To emulate "Control" you don't need {} because than it will send the "^" character only...

Are you using Send or SendWait?

Have you tried the other? could be a timing thing.

I don't think sendkeys is the best mechanism though when dealing with remote desktops; This thread seems to back this up; http://social.msdn.microsoft.com/Forums/en/Vsexpressvb/thread/01d1c501-880a-48c3-8b82-d3b08e974ff0[^]

Those a control characters to SendKeys. If you want to send those actual characters, you have to enclose them in the curly braces.

He's sending Control-V, which is correct in his code.

The technique, on the other hand, of using SendKeys at all is suspect.

I agree. Basically, using SendKeys is per definition unreliable. Best to code what you want (and keep control), rather than relying on a quirky method that can go wrong at any turn.

Try running remote desktop in full screen mode.
Apparentely, Remote Desktop only acknowledges key strokes in full screen mode.

Try sending an additional printable character afterwards, e.g. a space: "^v ". Some time ago, I experienced a situation where that helped, but I do not know why that worked...

Class Hierarchy To XML

What's involved in converting a hierarchy of classes to an XML file? I'm not talking about serialization. I just want to take a collection of objects and create an XML file out of it?

Thanks

Actually, that is serialisation, to XML at least. The path of least resistance is to use the built in XML serialisation.
If you don't want to do this you nned to use reflection to traverse the object graph whilst writing the XML to file.This is slightly harder than it sounds,as you also need to take into account collections and potential loops in the graph.

Personally, I'd go for the built-in option if possible. You can write your own formatter if the built in one isn't to requirements.

Yes, you are. Cue the wiki quote

serialization is the process of converting a data structure or object into a format that can be stored (for example, in a file...

Start with the docs for XmlSerializer here: http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer.aspx[^]. There are plenty of examples on that page of the default, as well as finely controlled serialization.

I'd like to write an application that monitors connections to my machine through the sessions portion of computer management. I have win7 32 bit and .net 3.5 .

Can anyone point me in the right direction on which c# methods I should be looking at?

Thanks!

You will have to look up the API for 'the sessions portion of computer management' (not sure what that is myself but hopefully you do!), and call the appropriate methods through P/Invoke.

Hi Ken,

Thanks for the response.

I was able to get this working today, the only problem is that I cannot close the session. It appears that this is a Windows thing, because I see the same behavior when I do so within computer management. I can right click and say "Close session" and then refresh and it will reappear.

I was wondering if you had any ideas on how to actually close the session?

In my code, I am calling session.Delete(); without any success.

Thank you

Blizzard Authenticator

The blizzard authentication is really cool, just as well as all other RSA tokens. I understand that synchronization plays an important role in this matter, but when using RSA or authenticated encryption, isn't its main goal based on time of the day that this information is generated? If so, if the server goes down, doesn't that mess up the synchronization with all other devices?

Re: Blizzard Authenticator [modified]

My understanding is that the Blizzard authenticator is purely a number generating machine.
It does not depend on the time - if you ever use an RSA token you will find that each time a new number shows a bar also decreases in size.
With an RSA token you need to enter the number generally while there are still two bars left due to this synchronization issue.
The Blizzard authenticator has no such countdown bar.

I think this question may also need to go to the lounge as it is not really a C# question Wink | ;)

For a heads-up, you need to get a GSM modem (or a CDMA modem), attach it to your PC and use the API provided with the modem to send SMS.

And do not use words like "important" or "urgent" here. People in CP help others in their leisure, it may be urgent for you, but not for us here.
