hi,keshav
u r adding a text wright and it is not working..
i think my question was not clear
i am having a datagrid and one of the column is made as a
column type=DataGridViewComboBoxColumn
and i am adding a rows like
Scenario_Designer_gridview.Rows.Add(filename);
where filename contains the list of files in a specifeid folder i am getting from folder browser.
now i want add the list of files to a that column...
i am getting error......
help me pls.
|

|

u mean to say that when the user clicks on the browse button, it should open a file dialog for only a fixed path, and automatically select all the files from that path, and load the names of the files in the data grid rows! right?
I will try to figure it out. It requires a little addition of code.
I will try it and let u know.

or do u mean that every row in that datagrid will have a column that comprises of a combo box that allows u to choose a particular file?

Hey, I wanna try to make a 3rd party prog that can control CS servs from outside (Like HLSW).
I know this is not the main forum for this, but I think that maybe someone here knows what I'm talking about and MAYBE help me (please).
Well, I could find several sites to deal with RCON cmds, and I even found a code (with a help of a friend) to connect to the server and exec RCON cmds, but however, I can't get the log.
This is a link that showed me a little about the log: http://www.hlstats.org/logs/[^]
but however, I could not understand HOW to get it.
If someone can help, PLEASE PLEASE HELP ME.
And if you have a prog\snippet for this this would help even more!
Thanks ALOT in advance.

Hello All,
I am using a datagrid, and I populate the datagrid, using a sqldata reader. The code is as follows.
SqlConnection conn = new SqlConnection("Data Source=" + Environment.MachineName + "\\WINCC;Integrated Security=SSPI;Initial Catalog=Logger; Packet Size = 32766;");<br />
SqlCommand cmd=null;<br />
SqlDataReader rdr = null;<br />
conn.Open(); <br />
cmd = new SqlCommand("SELECT * FROM RDPLogViewer", conn);<br />
rdr = cmd.ExecuteReader();<br />
while (rdr.Read())<br />
{<br />
LoggerDatagrid.Rows.Add(rdr["TypeLevel"].ToString(), rdr["TimeStamp"].ToString(), rdr["SubSystem"].ToString(), rdr["ClassName"].ToString(), rdr["FunctionUsed"].ToString(), rdr["Memory"].ToString(), rdr["Statement"].ToString());<br />
}<br />
rdr.Close();<br />
conn.Close();<br />
It is working perfectly fine. Does there exist an alternative or an additional way to populate the datagrid, more fast? I just want to optimize it.

Hi,
Why dont you try to use SqlDataAdapter to fill a data set and then attach that data set to the DataSource property of the DataGrid. I think this will save you some coding effort.

I think the way what you used to bind the grid is difficult. As coolestcoder told you can use sqldatadapter to fill one dataset. Then set the dataset as datasource to grid. One more problem what i find with your binding is,it's tough to implement paging on your example since sqldatareader is forward only. So better to go for dataset

HI,
Is it possible to do IPC with DOS apps using C#?
I have a 32-bit DOS App which takes in CMD line parameters. I need to get the results from this app onto a Windows Form.
The results are quite large, 25-30 MB....which is the 1. Easiest and 2. Fastest way to do it?
I'm right now looking for an easy way to do it, but a Fast way with minimum overhead would be great.
Examples and pointers would really help.
Thx

is it possible to lock a file so that only a certain application has privelege to write to it? how? i want to create an application that makes use of a log file such that the log file cannot be modified outside the application. Also, this means that only those users that have access to run my application will be able to modify the log file (through the application).
thanks in advance.

Have the application open the file and set the sharing appropriately:
See:
* File.Open[^]
* FileShare[^]

Hi Colin Angus Mackay,
I think DenClancy wants that a file ( even if a simple text file ) must not be opened without a particular application. Is this possible ? What if an Admin user tries to open this file ?
Actually I wanted to restrict access to some files, even if the files are simple text files (even to admin users). I heard about something called Access Control List. Is it applicable here ? I dont know the details of ACL. If possible, please reply in details.
Thanks.

coolestCoder wrote: Is this possible ?
As I pointed out, the application can deny others the ability to do anything but read the file. Or it can take exclusive control over the file too. See the previous links to FileShare.
coolestCoder wrote: What if an Admin user tries to open this file ?
Yes, even an administrator - Try it with a SQL Server database file. You won't be able modify it regardless of who you are logged in as because the SQL Server process has control over it. Not even someone logged on as the same user as SQL Server can access the file.
coolestCoder wrote: ctually I wanted to restrict access to some files, even if the files are simple text files (even to admin users).
You can change the permissions on a file as you need it. I'm not sure if you can lock an admin out though. If it is possible then it would only be a temporary situation as the admin would have the ability to grant themselves access again.

Hi!
I think the real question is how to permanently lock a file without an application that has to keep the file handle open all the time.
Sure you can set FileShare to None, but the moment your application ends anyone can access the file again.
The original poster wanted a way to deny access to a file for everybody even after the application has finished.

I think you could achieve something similar if you can create a separate user with a random password only your application knows and have your application set the access rights for the file so that only this particular user has access rights.
But an administrator could take ownership of the file and thus modify the access rights anyway...

thanks, but application works on my PC in others not (in others i have installed .NET Framework 2.0), do I have to install anything else?

Blue_Boy wrote: but application works on my PC in others not
There must be some difference between your PC and the others. In order to track that difference down you need a debugger. The debugger isn't necessary to run the application, it is just necessary to find out what went wrong. Then you can tell if there is something missing or not.
On the target machine you can install the .NET 2.0 SDK. That comes with a basic debugger. If your application has been built as a debug built it will help you track down the problem.
