what do you mean by "understatement"? you mean I've done the same in an other way?

The code you came up with is needlessly complex, doing multiple conversions that are both redundent and useless. Your code converted a text property to an int, back to a string, then broke that into an array of chars, then converted that back to a string again.
All you had to do is dive into the documentation on .ToString() and it would have made your life so much easier. It probably would have taken you the same amount of time to read that and come up with the correct answer to your problem as it did to try everything under the sun and come up with the bastardized statement you posted.

When there are 8,000+ classes (or whatever it's up to now) that probably happens more often than not to some degree.

I developed a SMS application, I use a timer to pool the modem every now and then for new responses if a response is found I launch an ResponseReceived event, then that event looks for the type of response, then when a new message is detected I launch the NewMessageReceived event from the ResponseReceived event. The main application receives this event and opens a new dialog window, but the problem is that it does not show the window. I can see the window in the taskbar but not on the screen. I tried forcing the window to show, go topmost, maximize, every thing, but no window. I suspect that this could be due to threading of the timer or something, can anyone help?

You're right: see the docs for the InvokeRequired property, and you'll understand more. Simply put, you can only do UI tasks on the main thread. There's an "Invoke" method and an "InvokeRequired" property on all controls and forms that ease things for you.

Thank you so much! How do I send variables to the method that I invoke?
<br />
private delegate void NewSMSReceived();<br />
protected void OnNewSMSReceived()<br />
{<br />
int Position = 1;<br />
Solutions.Gsm.Modem.SMSMessageReceive SMS = Gsm.ReadSms(Position,true);<br />
SMSReceivedForm NewSMS = new SMSReceivedForm(SMS);<br />
NewSMS.ShowDialog();<br />
}<br />
private void Gsm_NewSMSReceived(object sender, Being.IT.Solutions.Gsm.Modem.NewSMSEventArgs e)<br />
{<br />
lbInfo.Text = "New SMS received @ "+ DateTime.Now.ToString();<br />
Solutions.Multimedia.SoundPlayer.Play(Application.StartupPath+@"\NewSMSNotify.wav");<br />
<br />
this.BeginInvoke( new NewSMSReceived( this.OnNewSMSReceived) );<br />
<br />
<br />
}<br />

This becomes (I removed all the 'this.', I find it weird):
Invoke(new MethodInvoker(OnNewSMSReceived), new object[] { your variables go here });
Other alternative would be using properties, since you're on different threads, but will be invoking methods on the same object ('this.').

I just want to know if its possible to do the following, but first, some background. I have a com dll which I connect to through C#. The dll has a connect property which is the first method you call. This method attempts to locate an electricity server. I want to find out if I can stop this method from executing after a certain period of time if no server is found within that time limit. The dll has no settings to set a timeout, and the people who make the dll are to "busy" to do anything about it. It does throw an Exception when it does not connect, but this is after about 20 seconds, and I would prefer this to be around 5. Please let me know how to do this if this can be done.

I've tried stopping COM objects before (in C++, not in C#), and all I can say is that it's simply not reliable if you do it in-process (e.g., loading a DLL). I tried creating the object in another apartment, asynchronous COM calls, aborting the threads, etc, and nothing was reliable enough. After a while instability started to happen.
The only reliable way I found was using out of process COM servers (.exe), so as I killed the process, the OS done all the cleanup needed. I suggest you to load this dll in a surrogate process and kill it when you need to cancel the call.
I know that starting and stopping processes in Windows is not a fast task, but in some cases, it can be fast enough for what you need.

Got an web application where users can select applications they would like to use. They can choose several applications. The choices i want to store in a database. A table with fields like userid, appname. The combination of the two can occur only once.
I can of course use an insert statement and loop for the number of applications but i was wondering if .net has a better way. Something like filling up a dataset and passing the dataset to a insert method.
Glad to hear some suggestions.

I am implementing a UI for debugger, and trying to do a step mechanism where the current source code line is highlighted (its background is colored).
So basicly I am trying to set a background for the selected text (only).
Any ideas?
Thanks,
Orly

I believe that the RichTextBox is fast enough for a debugger, so I would suggest you to use it, as it's easy to change colors, fonts, etc, of the text.

It's called a Context Menu Shell Extension (there are others like Property Sheet Shell Extensions to add your own tab to the File Properties dialog.)
Search on CodeProject, there are several good articles and tutorials.
See this: Search Results[^]
Most articles are for C++ or MFC, but there's an article on page 2 about a property sheet extension in C#. Take a look.

Hi,
Please look at www.sahometraders.co.za. I have to do the website in ASP.NET, and I want to get started with the top menu. People say that I must use a user control for this. I'm not entirely sure how to do this. I will be using C#. COuld someone please send some sample code, or give me a link where I can download some good sample code on how to create this type of control. Any links to other good articles will be appreciated.
When will I use user controls? People say I must use a an includes files, so if I were to use an include file in the old ASP, would I then just have to create a user control every time?

I would have expected a class COMDispatcher and interface ICOMDispatcher as per the idl.Then why are the interface COMDispatcher and class COMDispatcherclass introcuded?Can someone explain the purpose of this modification while generating metadata.Any reference will also be appreciated.

Hello there,
I just wanted to make sure before I attempt to do anything. It's okay to concurrently access a file as long as it's only being read right?
Thanks

This is generally true. However keep in mind that you'll never know in advance what other running processes might do with the file you want to read. If the file has already been opened without the FileShare.Read flag set you will get an exception. Also you might want to set specific FileShare[^] flags yourself when you open the file (for example to prevent that another process writes to the file while you're reading it).
Best regards
Dennis
