Re: WPF MVVM Threads and a Log

I answered a question a while back about using log4net to log to the UI. I blogged about how to do it here[^].

I was brought up to respect my elders. I don't respect many people nowadays.

ah, that looks interesting. I'll give that a go, plus it looks like it might provide a base for more larger apps.

Thanks

I am writing a windows desktop application in C# 2008 and i wanna to have select for datatable :

IEnumerable<string> idsInA = dtd.AsEnumerable().Select(row => (string)row["ID"]);

it filters only on one row (ex.ID) but the thing i wanna is for three rows (ex:ID , Title , Path)
Ho i can do that ?

IEnumerable<string> idsInA =
    (from row in dtd
     where row["ID"] = idFilter && row["Title"] = titleFilter && row["Path"] = pathFilter
     select row["ID"]).AsEnumerable();

But this only returns one column, if you want all the columns, you would use something like this:

var rowsInA =
    (from row in dtd
     where row["ID"] = idFilter && row["Title"] = titleFilter && row["Path"] = pathFilter
     select row);

and then rowsInA is an IEnumerable that contains the row objects.

C# accessing a windows api

I am writing a windows desktop application in C# 2010 that will be calling a windows api. The user will enter some information, hit the submit button, and the windows api will be called.

My question is would you show me code on how to call the windows api, tell the windows api what you are looking for, and return any optional values obtained from the windows api?

This will give you just about any API info you need, with code[^]

An impossible task, since the code for each function is unique to that function. Go to MSDN, search for the function you are interested in, and read the documentation.

What functions in the Windows API are you wanting to call?

I will get calling an windows api that another programmer at work is 'writing'? Should I ask her how to call the windows api?

Pete O'Hanlon13-Jun-13 9:48

13-Jun-13 9:48

Unless you are working for Microsoft, the other programmer is not writing a Windows API. And yes, you should ask her how her "API" should be called.

The Windows API is Microsoft's own API for windows that they provide to allow you to call functions within the OS: http://msdn.microsoft.com/en-us/library/windows/desktop/ff818516(v=vs.85).aspx[^]

If someone else is writing a library and they are providing an API then they should be providing documentation for it's use.

C# using WPF

I want to write a C# WPF application using visual studio 2010. I want to be able to allow the user to do the following:

1. enter some data,

2. select a file from a directory path,

3. error message will be displayed if the user enters wrong data,

4. the user will hit the submit button and call a windows api.

Thus can you tell me how to accomplish this goal?

Create a WPF project in Visual Studio. Write some code. Beyond that, it's up to you.

In addition to Pete's comments, if you head over to the articles section you will find plenty of good samples of Windows forms applications, and how to use the various controls. Alternatively look here[^] and here[^] on MSDN.

Server 2012 remote powershell with C#

I'm having the toughest time finding / figuring out how to get remote powershell working with 2012.

Currently this is my code:

private void OpenRunspace(string username, string password, ref Runspace remoteRunspace)
        {
            // Convert plain text password to secure string
            SecureString pass = new SecureString();
            foreach (char c in password.ToCharArray())
            {
                pass.AppendChar(c);
            }

            PSCredential psc = new PSCredential(username, pass);
            WSManConnectionInfo wmci = new WSManConnectionInfo(new Uri("http://" + ConfigurationManager.AppSettings["ExchangeServer"] + "/powershell"), "http://schemas.microsoft.com/powershell/Microsoft.Exchange", psc);
            wmci.AuthenticationMechanism = AuthenticationMechanism.Kerberos;
            wmci.ProxyAuthentication = AuthenticationMechanism.Negotiate;

            wmci.SkipCACheck = true;
            wmci.SkipCNCheck = true;
            remoteRunspace = RunspaceFactory.CreateRunspace(wmci);
        }

The error I keep getting is "Access is denied". I've verified the credentials I am passign to it is part of the REmote Management Users group on that local server, ran the Set-User "Administrator" powershell enabled command in Exchange 2013

What else am I missing here?

You can use the web.config or app.config files for that. They are accessed through the ConfigurationManager class.
They are XML based files and have several sections that ConfigurationManager can read. One of those sections is "ConncectionStrings" (or something similar.)

See here[^] and here[^] and here[^]

hope this helps.
