hi
i am using to form in my application each form have a datagridview i want to transfer all the rows of one datagridview to other form datagridview how?

You can bound both the datagridview with the same datasource.

You can use this method to get the DatagridView DataSource.
public Form2(DataGridView dg)
{
InitializeComponent();
this.dataGridView1.DataSource = (DataTable)dg.DataSource;
}
|
|
|
|
|
i did't bound any datagrid to any datasource but i just added some rows to one datagrid and want to copy it to other form datagrid using the code
RegistrationForm rg = new RegistrationForm();
for (int i = 0; i < dataGridView2.Rows.Count-1; i++)
{
string[] values = { dataGridView2.Rows[i].Cells ["TestID"].Value.ToString(), dataGridView2.Rows[i].Cells["TestName"].Value.ToString(), dataGridView2.Rows[i].Cells["Charges"].Value.ToString(), dataGridView2.Rows[i].Cells["DeliveryDate"].Value.ToString() };
RegistrationForm.dataGridView1.Rows.Add(values);
his.Close();

Hey guys, I'm currently working on a windows application and I'm looking for some help from developers with this experience ... Currently it's being tested on a single computer after fixing all the bugs I'm planning to distribute it and my target is around 100 to 200 clients.
1- the best method for Creating an install file (other than visual studio built in one which I'm already using)
2- the best way to update the software (currently I have to reinstall it on the client's machine)
3- Any useful tips or articles on creating online update
4- currently I install SQL 2005 and attache my database, a friend of mine suggested SQL lite, which one is more efficient?
5- Security, I know it's almost impossible to guarantee this 100% but I'm looking to find the best method, adding CD keys which has to be confirmed online, having USB security keys, ... what do you recommend ?
Thanx guys, I'm looking forward to your tips and help and if you've got any articles regarding my question please share it with me cause I'm here to learn.
Regards,
K

Hi ,
I will Answer only About what I am Sure of ...
1- I use NSIS Script ( I love it )
4 - Sql2005 or Sqlite ?
SQL 2005 | Sqlite
------------------------------------------------------------------
Work on network (Server) | Work On Single Machine only ( embedded)
Hard to Deploy and Install | Copy and paste to Deploy
Up to 13.00 GB DataBase Size | Up to 2.00 GB Size
5 - I use SmartAssmbelly , and I never used Dongle before ( but you must take a look at www.safenet-inc.com[^])
I know nothing , I know nothing ...

Look into Click Once deployment?
I recommend SQL Server (at least the Express version), you never know when you may need to scale up in the future.

now the my program is running..
now to stop it...
run-> xyz.exe -stop //to stop
i'm thinking that when i write this last command, i use diagnostic class to kill xyz.exe process..
wat say.. m i thinking right... is there anyother way to do it..

|

I do that with my Windows Services.
|
|
|
|
|
wat m saying.. is that possible...
|
|
|
|
|
Possible? Yes.
Sensible? No.
What you are asking for is pretty much a windows service. You could do what you want, but it would be technically much more difficult than a service. Weren't you asking about TSRs earlier? The answer remains a the same, Windows services will do what you are asking, is there some reason you can't use them?

actually..
i dont know how to write window services...
and moreover m having just a month to complete my program...
my program does 3 works...
keylogger for security purposes,
watches mentioned files,
and kills mentioned processes...
now to that i've the knowledge abt all three...
but wat i'm lacking is the way i want to integrate them...

i'm unable to understand this services from that article..
i understood its using service controller class in c#..
but m confused where should i place my code to be executed in it..
it says that the control should be transfered to os after the service is executed. but i want my program to be kept running otherwise it wont be logging keys, or watching files, or killing mentioned processes..
i hope u got my point..

To be able to control a Service from the command line I do something like:
private enum Action
{
None = 0
,
Status
,
Install
,
Uninstall
,
Start
,
Stop
}
[System.STAThreadAttribute()]
public static int
Main
(
string[] Args
)
{
int result = 0 ;
try
{
Action action = Action.None ;
if ( Args.Length > 0 )
{
System.Enum.TryParse<Action> ( Args [ 0 ] , true , out action ) ;
}
switch ( action )
{
case Action.None :
{
if ( System.Environment.UserInteractive )
{
System.Console.WriteLine ( "Syntax: JunkService STATUS | INSTALL | UNINSTALL | START | STOP" ) ;
}
else
{
System.ServiceProcess.ServiceBase.Run ( srv ) ;
}
break ;
}
case Action.Status :
{
System.ServiceProcess.ServiceController svc =
new System.ServiceProcess.ServiceController
(
srv.ServiceName
,
System.Environment.MachineName
) ;
try
{
System.Console.WriteLine ( svc.Status ) ;
}
catch ( System.InvalidOperationException err )
{
System.Console.WriteLine ( err.Message ) ;
}
break ;
}
case Action.Install :
{
System.Configuration.Install.ManagedInstallerClass.InstallHelper
(
new string[] { System.Windows.Forms.Application.ExecutablePath }
) ;
break ;
}
case Action.Uninstall :
{
System.Configuration.Install.ManagedInstallerClass.InstallHelper
(
new string[] { "/UNINSTALL" , System.Windows.Forms.Application.ExecutablePath }
) ;
break ;
}
case Action.Start :
{
System.ServiceProcess.ServiceController svc =
new System.ServiceProcess.ServiceController
(
srv.ServiceName
,
System.Environment.MachineName
) ;
switch ( svc.Status )
{
case System.ServiceProcess.ServiceControllerStatus.Stopped :
case System.ServiceProcess.ServiceControllerStatus.StopPending :
case System.ServiceProcess.ServiceControllerStatus.PausePending :
{
svc.Start() ;
break ;
}
case System.ServiceProcess.ServiceControllerStatus.Paused :
{
svc.Continue() ;
break ;
}
}
break ;
}
case Action.Stop :
{
System.ServiceProcess.ServiceController svc =
new System.ServiceProcess.ServiceController
(
srv.ServiceName
,
System.Environment.MachineName
) ;
if
(
( svc.Status != System.ServiceProcess.ServiceControllerStatus.Stopped )
&&
( svc.Status != System.ServiceProcess.ServiceControllerStatus.StopPending )
)
{
svc.Stop() ;
}
break ;
}
}
}
catch ( System.Exception err )
{
System.Console.WriteLine ( err ) ;
}
return ( result ) ;
}

If you don't want to make your app a service and don't want to build a listener that listens for a close message, you can achieve your goal by periodically checking for the presence of an "exit" file (in the same directory as the application). The -stop command line argument would simply create the "exit" file and exit, causing all normally running instances of your application to exit.
Caveat: this is a cheesy hack but may meet your needs at a pinch.

Hi all!
I have another post about this issue, but I will try to explain myself a bit better this time (sorry for posting 2 times) since the previous post did not get any attention!
Here's the situation:
I have a WinForms project called WinFormsProj1. I have several settings in this project which are saved in a "user.config" file (which lies in "C:\Users\Kåre Tragethon\AppData\Local\WinFormsProj1\WinFormsProj1.exe_Url_********\VersionNo\user.config"). From my main application (WinFormsProj1) I can find the path of the "user.config" by:
Configuration _usrConfigLoc = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);
And then
string _filePath = _userConfigLoc.FilePath;
In the same solution I also have another project called WinFormsProj2. I want to access the user.config file to WinFormsProj1 from my WinFormsProj2 project. How can I find the file path?
I must point out that the path I am looking for is NOT the "C:\Program Files\WinFormsProj1......"!! I am looking for the path of the user.config file which lies in "C:\Users\The User\AppData\Local\AppName\AppName.exe_Url_*********"

Query for multiple occurrence in Column in a table
or to count which record is occur multiple time

This is really a SQL question rather than a C# one. To do this, you can use
select id, count(1) from mytable group by id
having count(1) > 1

Hi, all!
Here is the problem:
I'm writting some code that gets HTML page, and then grabs it's content. The content of the page is organized in multiple pages, and navigation between them is done by clicking on the page's number below the records (For example, there are 150 records, displayed in 10 pages * 15 records/page. Therefore, the web page contains 10 hyperlinks to other pages with records). Obviously, in order to get all the information needed, I need to loop through all the pages' links, download their HTML and afterwards parse the information.
The problem is, that I can only download 2 pages from the list. For some unknown reason, my code freeses after it downloads 2 pages. The order of the pages does not matter, for example if I start from page #5, I can only get pages 5 and 6.
According to common sense and VS debugger the problem lies in the method, that downloads HTML code
public delegate byte[] getHTTPdelegate(Uri address);
public void downloadPage(string URL)
{
client = new WebClient();
getHTTPdelegate dl = client.DownloadData;
IAsyncResult ar = dl.BeginInvoke(new Uri(URL), null, null);
while (!ar.IsCompleted)
{
Thread.Sleep(10);
}
rawPage = dl.EndInvoke(ar);
}
After downloading page #2, the application stops, and in a minute ar two throws an unhandled exception stating that operation has timed out.
Please note, that the problem is not "why isn't it working?", but "why does it work only 2 times?", when it should be downloading all the pages.
Any ideas will be highly appreciated.
