For a beginner don't you think this is a bit complicated? Connect both apps to a database, plenty of examples and easy for a beginner to understand

Explain where and how this senerio would occur. Are you saying the database wouldn't be able to deal with concurrency issues? How would using a webserive or writing to a file lessen this risk?

I've thought about it a little, and looked into it a bit more. You're right, race conditions don't seem to happen here. I got the roles backwards in my head. Sorry about that

My code is really basic using an Http channel to send a client activated object and it works fine when I run the client and the server from the same pc.. But when I try to run the server on one pc and the client on another, the client just shuts automatically. The 2 pcs are not connected in any way, but they both are using wifi.. and my code uses an http channel, so they can connect through the internet.. right? Do I need their IPs for them to find each other, or is the shared Http channel port enough? Sorry.. I'm a beginner.. any help would be amazing...

Maybe you could post a piece of the code of client and server? Could be helpful...
|
|
|
|

My server is:
public static void Main()
{
HttpServerChannel channel = new HttpServerChannel(9000);
ChannelServices.RegisterChannel(channel,false);
WellKnownServiceTypeEntry remObj = new WellKnownServiceTypeEntry
(
typeof(ProcessActivator),
"ProcessActivator",
WellKnownObjectMode.SingleCall
);
RemotingConfiguration.RegisterWellKnownServiceType(remObj);
Console.WriteLine("Press [ENTER] to exit.");
Console.ReadLine();
}
My client has:
HttpClientChannel http_channel = new HttpClientChannel();
ChannelServices.RegisterChannel(http_channel,false);
IProcessActivator.IProcessActivator process_activator1 =
(IProcessActivator.IProcessActivator)Activator.GetObject
(
typeof(IProcessActivator.IProcessActivator),
"http://localhost:9000/ProcessActivator"
);
process_activator1.Run("IExplore.exe", @"http://www.codeproject.com");
There's also a library called ProcessActivator and it just has the run command... I included the remoting references.. The code runs fine when i run both the server and the client on the same machine... but they won't work with each on a separate pc...

Nevermind.. I figured it out..
I was making a call to the local machine instead of the remote machine(IP address)
"typeof(IProcessActivator.IProcessActivator),"tcp://localhost:9000/ProcessActivator"
Solution:...
Pass the IP address of the remote machine to the client application
"typeof(IProcessActivator.IProcessActivator),"tcp://192.168.0.104:9000/ProcessActivator"

I would like to write a picture viewer app that outputs the image over the entire screen, not just the desktop. I can't seem to find the solution to write over the taskbar. Any help would be appreciated.
Thanks

You need to set the window state to be set manually, and you set the coordinates of the window so that the Top and Left are 0. You can use Screen.PrimaryScreen.Bounds to work out what the width and height of your screen is. Obviously, you'd need to do more work if you wanted to cover other screens in a multi monitor setup, but the Screen class provides access to the other monitor information in AllScreens.

Thanks Pete, but this will only cover the desktop, not the taskbar.

Set TopMost=true; on this window.

you can use:

DataView dv = new DataView(dtCompanyForm, null, "Id", DataViewRowState.CurrentRows);
//to assign dataview to datatable
dtCompanyForm= dv.ToTable();

Doesn't really matter in this case, what is the structure of your database.

Have a look here at MSDN[^]. This only creates database, but you can enhance it further to execute your whole script.

there are too many ways to do it, if you wish to use Linq to Sql Classes (.Net3.5), you simply create database with dbObject.CreateDatabase(); method call. or you can generate the create script with Sql Management Studio and then execute it with a sqlconnection object, otherwise there is tool named SQL_Packager[^] it makes these generating scripts and writing codes to execute it steps with simple wizarded UI.

Do not repost same question.
|

Make the "print" button a submit, when you click on it you submit form to page that stores this data in database, and then you redirect to a page which will re-render all this informaiton in gridview and call over JavaScript page print command which is called this way: window.print()
Maybe someone else has better suggestion, you could submit data over "AJAX", but, it's same thing, anyhow he need to submit this data, only if you would save it over ajax you would save some time re-rendering gridview.
