When Im trying to add reference to my class library, and choose the assemblies-tab, it says "No items found". No assemblies are listed
|
|
|
|
|
If nothing at all is being listed under the assemblies tab then something has gone very wrong with your VS installation or .NET installation. I suspect you have put something in the search box.
You were adding your class library under the solution tab - if it's in the solution as a project then that is the correct way.
Here's an article on managing project references[^] and another on adding references[^]
|
|
|
|
|
Don't create the reference to the library .DLL itself. Reference the PROJECT in the solution instead. Right click "References" in your project, pick "Add Reference...", In the nav bar on the left, open "Solution" and in the center box, put a check mark next to your library project. Click OK.

Why are you asking for an explanation of what appears to be someone's resume here ?

You must realise that most of us here have a low opinion of the recruitment industry as we have been subjected to their idiocies too many times.
Now this seems to be someone trolling with a sense of the ridiculous or you really are as thick as most of us think you are.

It's a job ad: if you don't understand the requirements, then it's a waste of time applying as you won;t be able to do the job.
Keep looking for something where you understand at least 75% of what they are looking for.

My Php file is returning this json. how can i covert it in c#.
{"response"[
{"user_id":"26","crtloc_lat":"47.678238","crtloc_lng":"-122.131416"},
{"user_id":"27","crtloc_lat":"9.350192","crtloc_lng":"-95.391006"},
{"user_id":"28","crtloc_lat":"47.678238","crtloc_lng":"-122.131416"}
]
}
php file is present at anybodyhere.net/returntest.php
My Code
public async void sendmsg() {
WebRequest request = WebRequest.Create(http://anybodyhere.net/returntest.php);
WebResponse response = await request.GetResponseAsync();
List<Responsemsg> responsemsg;
using (var stream = new StreamReader(response.GetResponseStream()))
{
responsemsg=JsonConvert.DeserializeObject<Responsemsg>(stream.ReadToEnd());
}
foreach (var item in responsemsg)
{
Console.WriteLine("id={0},latitude={1},longitude={2}", item.user_id, item.crtloc_lat, item.crtloc_lng);
}
}
}
public class Responsemsg
{
public string user_id { get; set; }
public string crtloc_lat { get; set; }
public string crtloc_lng { get; set; }
}
public class RootObject
{
public List<Responsemsg> responsemsg { get; set; }
}
</pre>
|
|
|
|
|
Your JSON is invalid - it's missing a ":" between the "response" property name and the value.
Once that's fixed, update your RootObject to match the structure, and deserialize that:
public class RootObject
{
public List<Responsemsg> response { get; set; }
}
...
RootObject responseData;
using (var stream = new StreamReader(response.GetResponseStream()))
{
responseData = JsonConvert.DeserializeObject<RootObject>(stream.ReadToEnd());
}
foreach (var item in responseData.response)
{
...
}

Well the error is quite clear - the path
C:\WSmfgIT\WSmfgIT\WSmfgIT\wsmfgit\wsmfgit\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction does not exist or the account that you are running this under does not have access to that folder.
For example, if you are running this on a server you won't have access to "C:\..." - Try using relative pathnames
Are you sure that the path is correctly constructed? The repeated sequence WSmfgIT\WSmfgIT\WSmfgIT\wsmfgit\wsmfgit looks as if something has gone wong
|
|
|
|
|
my actual path is this :
@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf"
|
|
|
|
|
The reason you're having a problem is because you're using Server.MapPath along with mapping to a specific address. Do one, or the other, and not both.
|
|
|
|
|
this is my path
@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf" so how should I declare it? can you pls help me..

Member 12016106 wrote: Server.MapPath(@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf" + filename)
The Server.MapPath method expects a virtual path within the current application. It should look something like:
Server.MapPath("~/workinstruction/pdf/" + filename)
You've passed in a physical UNC path, which won't work.
If you want to save the file in the UNC path, don't use Server.MapPath:
FileUpload1.SaveAs(@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf" + filename);
Member 12016106 wrote: cmd.Parameters.AddWithValue(@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf", filename);
Your query doesn't have a parameter with the name \\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf. I suspect you meant to pass that as the path:
cmd.Parameters.AddWithValue("@Path", @"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\workinstruction\pdf");

In your btn_upload_Click method, you've not set the command's connection property.

Thank You soo much for your kind explanation..
I got the answer..

I am developing a instructional aids for school, that should be able to lock student windows tab to one app, and he cannot access other app. This locking is on request sent by server, and the lock/unlock action should be performed in a timely basis.
I have looked into "assigned access", but it seems not suitable, because it require a special user account, and need a reboot to enter the mode.
Do you have any idea or direction to handle this?
Target platform is Windows 10.
|
|
|
|
|
Windows doesn't support this because, well, it's a shared system running many applications at once.
The only way I know of is that you'd have to install an application on the target machines that, on command, installs a global keyboard hook to catch and eat Alt-Tab, Ctrl-Esc and Ctrl-Shift-Esc. You'd also have to set the policy on the machines that prevent users from running Task Manager.
