Mobile apps are much the same as any ordinary app and C# will do it very nicely. Not sure if you can do mobile apps on Express though - does it have the emulator?

Err... Well, you could have one computer with a direct connection to the internet that all other computers connect to. The other computers on the network would have to connect to this machine so you could control from there what they get. Depending on how large the network is, you might need one meaty computer, or just set up a small server.
As for the code part, you'd need to make a server application to accept any incoming requests and send back the webpage / information you need to. There are countless articles and examples of making a server application here on CP and the rest of the internet, so you should read through some of those.

Hy everyone!
I know there is a c# operation, to watch a directory for changes, meaning to realize, when files are copied into it to handle them etc.
this could be done by filesystemwatcher (FileSystemWatcher watcher = new FileSystemWatcher(); )
but in which order are the files which are found in this directory handled? in alphabetical order or just picking one?
so lets say i copy three files to this directory
b_file, a_file and c_file in which order are these files handled?
and lets say there is already a d_file in it when i start the service watching, which files comes first?
because i want to realize a tool which takes the files describing what to do (in xml). so the correct order is important. therefore i have to know the files are handled in the correct order.
let's say a_file creates a file, b_file changes the contence and c_file copies it to it's destination.
so the "commandfiles" have to be handled in correct order. that's why this info is so important for me.
thanks for any hint.

The files will be handled in the same order as the IO operations.
Note you won't get any events for files that were already in the folder before the FileSystemWatcher is started (d_file)
|
|
|
|
|
so this means, when a file enters the directory, then the trigger is started.
if file a_file and b_file enter at (almost) the same time, is a_file handled first or the one which is first in?
to guarantee the correct handling of the files i have to take care, a_file is there before b_file etc. is this correct?
because changing contence before creating a file won't work  or updating data which is not there because the last command should have put the data in there 
thanks for your info.
stephan.

It handles the first one in first.
If the order is important then wait until you get a full set in before starting processing - until you have them all you can't do anything anyway, as far as I can tell from your posting.

I have 6 comboboxes that are exactly the same. Just that the answers vary. Now I have an xml file that goes to a dataset. I tried to set the same table as the datasource in the xml file to all 6 cb's, but to bind the selecedValue property to 6 different variables. Basically what happened is that all the values of all 6 boxes ended up being the same. I ixed it by making 6 different entries in the same xml file that were identical except for the name. I personally think this is a waste and would like to now if there is any other way to do this.

Hi,
Use the clone property of the datatable to create seperate instance in memory.
Sample Code
ComboBox1.DataSource = Dataset.DataTable;
ComboBox2.DataSource = Dataset.DataTable.Clone();
ComboBox3.DataSource = Dataset.DataTable.Clone();
ComboBox4.DataSource = Dataset.DataTable.Clone();
ComboBox5.DataSource = Dataset.DataTable.Clone();
ComboBox6.DataSource = Dataset.DataTable.Clone();
Remember the Datatable is a type of Reference Variable.
Regards,

it doesn't work. with out the clone it works though.
This is the code
cbBp1Position.DataSource = xmlDataSet.Tables[27];
cbBP2Position.DataSource = xmlDataSet.Tables[27].Clone();

Hi,
I am working on a windows service that monitor a path and does some upload based on the FileWatcher class. As per microsoft, it say that "More than one user Service may run within the same process". Therefore, i created two services (component classes) in my windows service project and added an instance of each to the service to run as shown below:
static void Main()
{
ServiceUtility initUtl = new ServiceUtility(Constants System.ServiceProcess.ServiceBase[] ServicesToRun;
ServicesToRun = new System.ServiceProcess.ServiceBase[] { new exchangeRateFileWatcher(), new KYCFileWatcher() };System.ServiceProcess.ServiceBase.Run(ServicesToRun); }
However, i read that the second service will run only if the first one fails. Can you please tell me whether it is possible (and how) to run the two services within the same process (i.e exe)?
Thank you for your kind help
Carpe diem,

That's nonsense. I have service processes running up to eight Services.

While leaving unsaved form, the system should alert the user that the data is not saved and user should get option to save the form before moving out of the form.It is a windows application in .NET framework coded in C#.
|

Setting a flag on OnSaveButtonClick event and by handling FormClosing Event I think you can check this one.
class mainForm
{
....
private bool isSaved = false;
...
private void OnSaveButtonClick(object sender, EventArgs e)
{
SaveFile();
isSaved = true;
}
private void On_FormClosing(object sender, EventArgs e)
{
if(!isSaved)
{
MessageBox.Show("Data is not saved!");
e.Cancel = true;
this.Focus();
}
}
...
}
Hope this helps. Good Luck.

Hi,
I have created a windows service which monitors the activities of files on the server. This windows service is using a filesystemwatcher.
Every time there is an activity, i.e. when a file is moved or created, etc., then the system sends an email.
All works fine.
Question:
Imagine something will have to get installed on the server and the user forgot to turn off this windows service. Then as a result, a lot of emails will get sent.
This is what I am trying to avoid (Sending un-necessary emails).
Ideally, the user will turn this windows service off but what if he doesn't? certainly we do not what the system to send so many emails as the result of something being installed which can cause alot of files movements and creations, etc...
Thanks

Well, if you were stupid enough to set the folder to C:\ and then allow it to watch subfolders for "*.*" as well, you deserve what you get.
How about this... write the service to be more selective about what it's watching for. I know, this might be a huge mental leap for you, but sometimes, programming requires, ummm...., programming.

What would you do if someone decided to copy 500 files from somewhere? You need to reconsider your requirements and design.

Hi,
That will not happen as this system will be used for files which are not supposed to be changed.
Thanks
