I don't know I get your problem correctly but this is I can tell you:

indows service has CanStop property,set it to false and after your proccessing finished set it to true.

CanStop = false;
if(job is done)
 CanStop = true;

Before sending the data send a datatype maybe as a enumerated type, integer or string.

Maybe create a struct that has a datatype field?

Just some ideas...

You should search CodeProject. There is lots of examples and topics regarding socket programming.

How do you know the data types? You're the one sending and receiving them, so you dictate what those structures are. If you didn't create these structures for either the client or the server, then you need to consult the documentation for the socket client or server that you're trying to talk to. As far as sending files, you just send them using a buffer (a Byte[] array) as is. For strings and XML, just send the character data using the proper encoding (see System.Text.Encoding for more information). You get the Byte[] array for the characters based on an agreed encoding between client and server. You can either assume a single encoding between the two, or send data (much like HTTP, SMTP/MIME, etc.) using an encoding that one dictates.

Assuming you're the same person as before, I already covered this with you: http://www.codeproject.com/script/comments/forums.asp?msg=694424&forumid=1649#xx694424xx[^]. InternetDial can accept a phone number to dial.

Also, creating an actual connection file/config seems to be platform dependent. You should search MSDN Online for ways to do this.

Runtime Control Resizer

I am after a component that will enable users to resize visual objects such as an image at runtime. Just like in a standard art package.

I wrote 1 myself in Delphi and I could port it to C# but I am not sure how I would implement some of the Mouse capture routines...

Besides there must be an open source control that I can use/develop further to achieve what I want.

TIA and Merry Christmas

Well, did you try searching for one? There should be plenty of examples here on CP.

Also, read the documentation for the System.Windows.Forms.Control class. That has all the mouse events and properties you need to do this.

Application configuration?

I am new to C#. I am developing a small windows application to train myself with. I faced an issue and can't figure out a good approach to it.

My application needs a few configuration settings that shall be available for altering from users interface. I can build a form etc. but the problem is that I don't know how to keep custom settings. I tried application configuration file, defining a custom section and using IDictionary class instance for reading them. Well, I can read them but can't save them as they only get saved in System.Collections.IDictionary and don't get saved in the application config file.

Is there any simple way to arrange custom configuration and read-write it?

Can someone share a simple understandable example of it?

I hope I explained it clear enough.

Thank you all.

However, the code in the article looks bit complicated. Can you (someone) maybe give me a simple example of reading/writing a couple of settings?

like nick : real name?

thanks a lot lot lot!

Re: Application configuration?

Heath Stewart19-Dec-03 3:27

The .config file is just an XML file, so use the System.Xml namespace elements to append/insert/delete your settings. Note that this will not update your configuration options while the process is running. For information on how to do that, search the comments for this forum for keywords like AppDomainSetup because I've already covered how to do this a couple times. Of course, you could always update your settings in the running, cached instance if you provide an instance property for your configuration section object (which the IConfigurationSectionHandler implementation creates) and update your UI accordingly.

Look at XML serialization. You can create an xml file that contains your app settings. You would simply 1. open a file stream 2. create xml formatter 3. serialize the settings you choose to the xml file.
Take a look at serialization. You could use the .config file but this is read only, therefore you cannot create a user interface to modify it.

Re: Application configuration?

Heath Stewart19-Dec-03 4:56

Heath Stewart

19-Dec-03 4:56

And if the config file contained other stuff not for his section? This would NOT be a good idea because the other IConfigurationSectionHandler implementations provided in the .NET BCL do not use XML serialization. XML Serialization would wipe out the file and create a new one (based on your stream preferences).

You need to execute a SQL "CREATE TABLE" statement. Here is the documentation for MS Sql

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_create2_8g9x.asp[^]

That should give you enough to get started...may be different for other DB's, just read the documentation for their specific "create table" implementation.

Use a custom ListViewItem or something with the properties you want, and in the handler for the ListView.SelectedIndexChanged event, set the PropertyGrid.SelectedObject to your custum ListViewItem. You should read about the classes in the System.ComponentModel namespace for ways to provide custom TypeConverters and UITypeEditors for those properties if you require it.

ToolBar flat style

Hi all!

Possible do toolbar flat as in IE6.0?

I know that in VC6.0 this was not a problem.
But in VC.NET, I can not do this.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
