Hello, I'm asking yet another question to all of you geniuses.
I've gotten nearly every function working in the program I'm developing for work. The one thing I'm missing, however, is the ability to run commands on remote computers.
At first, I was hoping there was some .NET function to do this easily (you can start and stop services, so why not apps?) However, it does not appear so. Perhaps I missed one.
My next guess was to try to start telnet, and try to use SendKeys.Send() to send my commands... however, the commands pass into my Command Prompt before telnet finishes connecting.
The actual problem is that i'm hoping for a .NET managed way to run remote commands. A workaround for telnet like that would be usable, but only as a last-hope sort of thing. If possible, perhaps there is a .NET managed way to perform the task without running DOS commands remotely? This is what I'm trying to do:
RemoteComputer comp = new RemoteComputer("Target");
comp.Run("wuauclt.exe /resetauthorization");
comp.Run("wuauclt.exe /detectnow");
I'm simply trying to get the remote computer's Windows Update Agent to reset authorization, and then detect updates.
Thanks in advance to any of you who can help.

I suspect you need to have a program installed on the target computer, which you can communicate with. Otherwise, Windows would have no security at all, right ?

Well, the security is not an issue.
Whatever the method I try to utilize, my account has Administrator rights on all of the target computers....... but perhaps I can work on the "Install a Program" idea.
Can anyone teach me about making a pushing services? I only know how to Start and Stop them remotely.
edit:
Actually, i found a great tutorial on how to make basic services. Cool.

How do you select the row that has the ">" pointer on it on the DataGridView? I guess i am looking for the current row or the active row or the row that has focus.

I have a datagridview bound to a datatable. One varchar column is visible and the datagridview automatically creates a tooltip for the entire column's data when it does not fit in the current column width. How to I access the underlying tooltip so I can adjust the time the tooltip is displayed? Actually, I would like to force the tooltip to remain visible while the mouse is pointing to a row in that one column datagridview.
Thanks for you help and suggestions.

Hi,
Im trying to clarify whats the best method to join columns from 2 datatables which have a relation into one DataGridView.
Example:
Customers Table:
id
name
id_country
Countrys:
id
name
Then I have them linked using DataRelation and my DataGridView points to the Customers Table, datagrid wizard shows only fields from Customers Table and the only way I know to add them to the view is changing the select query of the DataAdaptor doing a join like:
Select customer.id,customer.name,customer.id_country,countrys.name FROM customer,country WHERE customer.id_country=country.id;
or using the inner join...
But is there a better way in C# to do it without changing the main query of the dataapapter, i saw something called Child() in Expressions , but was imposible to put it working.
Thanx in advance,

Hi all,
I am trying to change the size of label control but its not changing. I am trying to change it within form aswell as by changing it from property, but its not working. It gets back to its same small size.
This problem is in VS2005, whereas when i try in VS2003 it works fine.
Is there anything i can do for this matter ?
Thanks

Is the AutoSize property set to true ?

I'm building a Control descendant that overrides OnPaint() to draw itself according to its Enabled state; and I've overridden OnEnabledChanged() to call Invalidate(). However, when setting Enabled, OnEnabledChanged() is never called. What am I doing wrong?
TIA,

Hi fellow C#-ers
I have a question, hope there's someone out there that might give me a possible solution to this issue.
Basically I'm trying to parse a string (the query string) to my returnResults method which in turn returns a DataSet object. What I'm trying to achieve is to strip down the query string and work with a certain number of character which in turn will be parsed to my SqlDataAdapter to provide it with the table name.
So, let’s say my query string looks like this:
<br />
SELECT * FROM Product<br />
All I basically need is the table name, in this case "Product".
How is it possible to only strip the string of the character "Product" ?
<br />
<br />
public DataSet returnResults(string query)<br />
{<br />
SqlDataAdapter sqlDA = null;<br />
DataSet ds = null;<br />
StringBuilder str = new StringBuilder();<br />
string tableName = null;<br />
<br />
str.Insert(0, query);<br />
<br />
tableName = str.<br />
<br />
<br />
return ds;<br />
}<br />
<br />
Your feedback will be much appreciated.
Thanks!

You can use a regex that looks for the word 'FROM' and then grabs the word after it. You could even find that with string mashing
It's a shame your code is dealing with SQL this directly

Hi Chistian,
Thank you for your response.
I also would like to have your ideas when you said

Hi,
there are basically two ways:
1)
string operations
there is String.IndexOf(str) to locate a substring,
String.Substring(start, length) to take a substring,
String.Trim() to remove white space at start and end,
and String.Split(separator, times) to split a string by a separator
In your case, I would try something like:
int i=s.IndexOf(" FROM ");
s=s.Substring(i+5);
string[] sa=s.Split(' ', 2);
s=sa[0].Trim();
alternatively you could split first, then search which array element contains FROM
and use the next array element. Or just assume it always must be the fourth element...
You should carefully choose your startegy to locate the stuff you need.
2)
regular expressions
very powerful, not very intuitive; in this case I would prefer string operations

Hi Luc,
Thank you for providing me with a solution.
It makes sense now!
I have to be honest, I haven’t had to deal with string manipulation in a long time.
I appreciate the feedback.
Thanks.

I can't install Visual C# on my PC! When I try to install it, it starts, and there is this line at the bottom that says "Re-Establishing the connection... (Attempt 1 of 5)". The "1" eventually gets up to 5 and then I get an error telling me the setup has encountered a problem. Is the setup trying to establish a connection with the internet? My PC doesn't have internet - I have to use my dad's Mac. Any suggestions?

The basic install from the Microsoft site is just a bootstrap installer, so you download a small program that presents the options then you only download the bits you actually want to install. If you don't have an internet connection this installer won't work.
However, there is a solution. You can download a CD image in either ISO or IMG format. The download and installation instructions can be found here: http://msdn.microsoft.com/vstudio/express/support/install/[^]
If you are downloading from a Mac, the burning an ISO image onto a disc will be different.

My dad's mac does not have the ability to burn to a cd. to transfer files from one computer to another i've been using a 128MB USB. But thank you for the help! Now I know what the problem is. My parents keep saying that they're going to get a usb connector that will recieve the internet from our router. (They said this a really long time ago, yet it still hasn't happened )

Hello Everybody,
I want to retrieve HTML TextBox value from Code-Behind. I can't make it Runat="Server" as i am doing some Javascript functionality. When i am making it Runat="Server" my JS function is throwing an error.
Please help..
Thanks in advance
|
|
|
|
|
As long as the text box has a name and is part of a form, you should be able to query the Request to find the value. Something like string s = Request["MyTextBoxName"];
|
|
|
|
|
Thanks for your reply...
Actually i had bind that textbox in a DataGrid.
I am new to C# so please help..
|
|
|
|
|
Well, I definitely would need more information on this and I'm not sure on your familiarity with ASP. Could you describe what exactly it is that you're trying to do with the text box in your data grid?

Actually you still use JS on server side controls (runat=server).To reference these controls you can use the following:
<br />
var oControl=document.getElementById("<%=your_control_ID.ClientID %>");<br />
To get/set a value , you can use the following:
<br />
oControl.Value<br />

Whenever I run a program such as Windows Notepad, there are little dots in the lower right corner that make it easier to resize the window (they make it so your mouse doesn't have to be right on the line). Could anyone tell me how I can get these in my programs? Thanks in advance.
