Re: Executing an .exe file on server trough ASP.NET as Administrator

29-Apr-03 10:06

Hi...

I have some problems. I need to reboot my FTP service on my server trough an ASP.NET UI. I've tried to use Impersonate to gain administrator access, and use Processes to execute the command. This won't work, since impersonated access aint interhited to the process.

The next thing we tried, was to use some Windows API calls like CreateProcsessAsUser and CreateProcessWithLogonW, witch worked localy in a console app. (Used task manager to be sure the right user was executing the process). BUT, when using the exact same code, trough ASPNET, the ASPNET account was the account executing the .exe file.

So, witch options do i have? Anyone got file execution trough ASP.NET to work? This is driving me crazy.. Would love to se some code samples from people executing .exe files trough ASP.NET using C#.

*frustrated* Frown | :(

confused:

A suggestion is to create a windows service. Doing so, you decide (service properties / LogOn tab) under which logon the service is running. Then build an ASP.NET page which awakes the service on demand.

Agree..

This was what i was thiking avbout, BUT, i have one concerne, witch is that the problem is not my code but BulletProf FTP server. The reason is that in the middle of my frustration a system SP in SQL Server came in mind: xp_cmdshell, witch allows
you to execute shellcommands on the server. I created a .BAT script rebooting the server. If i double clicked the .bat file, it rebootet my FTP server, but, if i simply typed "EXEC xp_cmdshell 'c:\myscript.bat'" nothing happened. This is realy strange!

I have never written any windows services, but i was thinking that this might be the solution. Once i have the service up and running, i can set permissions to the service, and access it trough ASP.NET?

Am i the only one experiencing these problems executing .exe files on the server..?

Tnx for the help so far..

PS! Other suggestions on how to reboot my FTP server is greatly appreachiated.

(Sorry my bad english, my head is getting tired, and my mother thounge is Norwegian..)

Not sure if the WINAPI methods are the key. Since, the CreateProcess... methods worked just fine in a console app, but in a asp.net app, it simply wouldn't execute correctly. I did manage to execute the command as Administrator (according to the Task Manager) but, it didnt work... Anyone know if Bulletproof FTP Server have any issues like this?

Change local hostname using WMI?

29-Apr-03 11:11

A full fledged Windows Form app can run inside IE6, inside a web page. Now you need to find (or better, write it on your own) a Windows Forms which does draws object models. My suggestion is to look around gotdotnet.com samples, sourceforge,....

Plain text in a RichTextBox

Re: Plain text in a RichTextBox

29-Apr-03 5:34

Hi All,

I'm having a problem that I hope will be simple to solve. I have a RichTextBox that I don't want to format text. By this I mean if I copy a piece of text that is say bold and italic when I paste it into the RTB I don't want it to have those characteristics (unless the Font specified for the RTB has them). For an example lets say that font in my RTB is 8pt and I copy something that is 14pt when it's pasted it gets pasted at 14pt, I don't want that. Is there any way to get around this?

Thanks

I have a DataGrid in my windows app. One of the fields is a date time type. It's showing up at a date in my DataGrid. I really need to see the time too. How can I change the format of this one field in the DataGrid?

To change the format of a column, you need to set the Format property of the DataGridTextBoxColumn corresponding to the column. See the example code under DataGridTextBoxColumn should help.

Thanks you for your reply.

In my application I'm trying to display records in a table that let me know that some services I have written are working. At this point I'm updating the display on a button click. I tried to apply the code I found in the example you pointed me to. You can see the error message from my exception trap. Can you tell me where I when wrong?

private void m_btnUpdate_Click(object sender, System.EventArgs e)
{
this.sqlDataAdapter1.Fill(this.imAliveDataSet1,0,0,"ImAlive");

// Gets the DataGridTextBoxColumn from the DataGrid control.
DataGridTextBoxColumn myTextBoxColumn;
myTextBoxColumn = null;
// Assumes the Time column is a DataGridTextBoxColumn.
try
{
myTextBoxColumn = (DataGridTextBoxColumn)dataGrid1.
TableStyles["ImAlive"].GridColumnStyles["Time"];
}
catch (Exception excpt)
{

string strMsg = string.Format("{0} Exception caught.", excpt);
}

// Gets the DataGridTextBox for the column.
DataGridTextBox myGridTextBox;
myGridTextBox = (DataGridTextBox) myTextBoxColumn.TextBox;

strMsg "System.NullReferenceException: Object reference not set to an instance of an object.
at FordMon.Form1.m_btnUpdate_Click(Object sender, EventArgs e) in c:\source\ford\fordmon\fordmon\form1.cs:line 227 Exception caught." string

Is there an method or a way of preforming a SQL SELECT statement on a DataTable so that it returns a array of Rows?

The DataTable.Select() method won't do the job as my query is a bit too complex for me to use it.

This is my SQL query:

SELECT COUNTY_ID , NAME
FROM TOWNS
WHERE NAME IN
( SELECT NAME FROM TOWNS
GROUP BY NAME HAVING COUNT(*) > 1);

Do I need to use a SQLDataAdapter or something? Just a guideline on how I should go about doing this would be helpful.

Thanks

While a data set has some of the features of a relational database, it's not got a full SQL interpreter, so DataTable.Select won't do what you're looking for. If your data is in SQL database, you can issue the query with a SQLDataAdapter as you suggest.

Hope that helps.

How can I to determine when socket connected to my TcpClient is close connection?

I do this...

IPAddress ipAddress = Dns.Resolve(Dns.GetHostName()).AddressList[0];<br />
TCPListiner = new TcpListener(ipAddress,PortNumber);		<br />
TCPListiner.Start();<br />
<br />
while(true)<br />
{<br />
if (TCPListiner.Pending()) <br />
{<br />
TcpClient TCPClient = TCPListiner.AcceptTcpClient();<br />
NetworkStream LNS = TCPClient.GetStream();<br />
}<br />
}

then I send some text throw NetworkStream LNS. Client can close connection. And result this....

Hi, I have a problem with drag and drop: every sample about it i have found shows only how to drag a text from a textbox to another or a listview/treeview item to another. Instead, I have some controls (some shapes) and i need to allow to the user to drag them over the form like the visual studio IDE, with the resizing handles, the drawing of the dragged control's border, etc... exactly how the IDE! Can anyone help me, showing some samples (in vb.net or c#)?
