If you're new, how come you previously asked this:
at first excuse me because of my poor english i have written a program for sending an image or for video conference via internet with sockets and i am using tcp protocols my problem is that when i test program on my computer it works fine but when i test it over internet with between two pcs the reciver cant recieve image correctly minwhile i am using dial up
If you're really new, why are you working on such complex things ? Either way, why did you ask twice ? And how come you didn't just search the site or google in general for the many examples that exist ?

If this is true, then this is a dumb task for you to attempt. Try learning some C# first before you worry about more complex tasks like this. Otherwise, you're doomed to failure, no matter what you do, you'll run against your lack of basic knowledge in trying to impliment it.

Hi,
I am trying to insert/update/delete a field from sql server table using dataadapter in c# windows application.
Here insert and update are happening,but 'delete' is not working
I will show my delete part :
public int UpdateAllUserDetails(DataSet dsUsers)
{
private SqlConnection connection;
private SqlCommand command;
private SqlDataAdapter dataAdapter;
connection = new SqlConnection(ConfigurationManager.AppSettings.Get("conString"));
connection.Open();
dataAdapter = new SqlDataAdapter(command);
dataAdapter.DeleteCommand = new SqlCommand("DELETE FROM UserDetails WHERE vUserName=@vUserName", connection);
dataAdapter.DeleteCommand.Parameters.Add("@vUserName", SqlDbType.VarChar, 50, "vUserName");
int ret = dataAdapter.Update(dsUsers);
return ret;
}
can somebody say what is missing here?

Try and run the same sql statement in your DBMS as it will tell you what if anything is wrong with your statement. My guess is that you may have some dependencies in your tables, that prevent you from deleting.

Thanks kstls,
But I have no dependencies for this because i am trying to delete some newly inserted userdetails data, which will create a new field in that single table only and not in any of the dependency tables.
Here by debugging the code i am getting the update command as :
"DELETE FROM UserDetails WHERE vUserName=@vUserName"
which when run directly in DBMS just replacing vUserName as 'testuser' which is the primarykey vUserName :
[ DELETE FROM UserDetails WHERE vUserName='testuser' ]
is deleting properly
But not working from code

Hello,
I am making one windows application in C#. I am using SQL Server as database.So, my question is I want to deploy the .exe file to the client with out installing sql server in clients system.
to do that what files I should supply to him with SetUp exe.?
If it is necessary to install SQL Server in client system how can i do? I want to install this exe in almost 100 systems.
As I am new to Windows Application, can anyone explain about it... or give some article links so I can understand the whole processfrom creating application to End User deployment.

You should not need to deploy any SQL engine or code to your client systems. You should have one SQL Server to which the clients connect. They just need to have the relevant connection string.
If you are deploying this as a separate database for each user I would suggest something lighter such as SQL Server Express Edition. This for the secondary reason that the Express Edition is free whereas installing a full SQL edition on 100 machines will cost you upwards of £400,000 (gbp) that is $700,000 (usd). That is the approx going rate for an academic licence installation of SQL 2008 * 100 which is the cheapest licence available.
If you have knowledge, let others light their candles at it.

If the computers all run their own local DB, then an Access DB may have been better from a deployment POV, or SQL Server Compact. As it stands, you may need to install SQL Server Express, configure a connection string and deploy your DB onto it.

hi
How to open external program from my C# program (Windows-mobile) ,
and give this external program the focus ?
thank's for any help
|
|
|

Not very helpful my friend.
This has been reposted a couple of times as no-one seems to know the answer. Google does throw up how to launch another application, but setting the focus is rather more difficult. I don't know how to do it on Windows Mobile, the api's are all different from Windows desktop or server, and I did a bit of checking around as well. Came up dry.
If you have some good search terms that find the answer to the activation problem maybe you could post them here. I am intrigued as to what you searched for if it is so easy to find.
If you have knowledge, let others light their candles at it.

Perhaps you should then try the mobile development forum, it seems to be more geared for your issue.

In normal windows applications this will work
System.Diagnostics.Process process = System.Diagnostics.Process.Start("ProcessName.exe");
Something like that but i am sure you that you need to use the System.Diagnostic Namespace.
Another solution could be to use System.Reflection but you need to do some more research on how to use that namespace but i am certain it's possible with System.Reflection.
Best of luck

My first page on load remains minmized but all other related pages remain in normal state. the fact is that its window sate property is in normal state..how can i handle it in c# windows application.Can anyone help to solve this issue.

Set the property for initial window state to something other than minimised.

its normal state only but only that single page is loading so.
|
|
|
|
|
The problem is that only on page load for the 1st time..the next time we open it it will open in normal mode.
|
|
|
|

If you have it set correctly, then you must have some code that's causing it to minimise.

il explain u the flow.After login we enter into a new registration form that form is minimised.but if we close that registration form n then open, it wil open in the normal state.
|
|
|
|
|
Well, then you need to take the code that shows the form, and explicitly mark it to not be minimised. I repeat, you either have a problem in your code, or you have a property set wrong.
