Re: How to get all the instance of a windows Service using WMI?

1-Jun-07 8:53

Are you sure it is a windows service? You can only install unique named windows services so I am a little confused by your statement about User can create multiple instances of the same service. The service is always running and perhaps the service launches a windows app then or something?

Of Course it is a windows service...The name of the Service is Of Course Unique...but has one Executable.

people laugh at me because they say im different and I laugh at them because they are all the same.

How to access the data in a "DataSet" rather than a "DataGridView"?

Hello everyone,

I have a DataGridView which is populated by data from a remote DataBase server. The following code show this:

//create a mysql DataAdapter<br />
                OdbcAd = new System.Data.Odbc.OdbcDataAdapter("SELECT * FROM company;", OdbcCon);<br />
<br />
                //now fill and bind the DataGrid<br />
                OdbcAd.Fill(myds4, "company");<br />
<br />
                //Display the table "company" in the datagridview controller<br />
                dataGridView4.DataSource = myds4.Tables["company"];

I was wondering if it is possible to access the data in the DataSet rather than in DataGridView?

For example:

I am using the following line of code to get the "company_name" value and display it in an TextBox.

txtCompanyName.Text = dataGridView4.Rows[FilterCompany_id].Cells["company_name"].Value.ToString();

My question is, rather than tapping into DataGridView4; can I tap into "myds4" which is the DataSet holding the entire unfiltered data since I am applying filters to the data shown in the DataGridView?

Thank you very much and have a great day.

yes you can. myds4.Tables["company"][rownumber][columnnumber] or myds4.Tables["company"][rownumber]["columnname"]

shortcut to trigger event when not in focus

does anyone know a way to make an event trigger if a key combo is pressed ( lets say ctrl+alt+insert) that would trigger an event to go

the problem is that the app may not be in focus

You can do it, but I am not sure you really want to. If you hook into the windows message loop you can pick up on all windows messages includeing keyboard keypresses, but it is pretty intensive and would most likely affect the proformace of your application and perhaps the performance of others as well. I guess I would ask why do you want to do this? Is there a better way to do the same thing? It would be un likely that your users would know this key press short cut.

Now if you are trying to write a nice little hack that is looking for control - alt del and then you are trying to get the password typed it etc. that is another issue. You won't find much help here on this site for that type of stuff.

the problem is that they are working seamlessly

there is an application they use that is run on a remote server

and on occasion it locks up and the user does not have access to ctrl alt delete becuase it is running on a remote session and that would open taskmanager for there local comptuer

the only solution i can think of is to run another application with the remote application ( two applications) and when ever it locks up set it a key stroke command so that the second program (my program) kills the first which will respawn in a few seconds

since the second app will not have its windows displayed i dont know how else to trigger it other than to use a keyboard shortcut

also since they will be wokring in the other application, My app wont be the primary focus

In the remote session you can right click on the task bar at the bottom and select task manager. That way they can see the task manager on the remote PC. I think that would be the best option.

i think you missed the part about it running seamlessly

yes its a remote desktop but only the one application is displayed on the users computer

it gives the illusion that its running localy

so the taskbar and the start button all that stuff is you local compuer

just the app is displayed and run remotly.

Wow, that is different. I guess that isn't the design I would go with. I am assuming this is a windows application? Is there a reason it needs to run on the remote server? Do your users only have lame PC's so their pc's won't actually run the app? Or perhaps you don't want to load the .net framework on their pc?

You can launch a windows app from a network server and it will run locally on the user's PC as long as the trust has been set up. I have actually written an article on this:

Anyway, I think I would look at some other options to get out of that situtation if possible.
