Member 4487083 wrote: only testing public members
I'm not saying don't test them, I'm saying don't call them directly to test them. To test the private method in my example I'd write test cases that started with the public method and manipulate the inputs in order to fully exercise the private one.
Member 4487083 wrote: a unit eg. a single method
I'd call a unit a class, not a method or a property. When I link to a third party DLL to import some functionality, I'm importing the classes not individual methods.
Member 4487083 wrote: which may include using things in a way that they weren't necessarily supposed to be used
Of course, but I always honor the contract of the classes that I'm testing. If a class has a method that takes a string parameter I'll throw everything I can think of into that parameter to stress the method but if you go outside the contract then what are you testing? If something is private then it's not supposed to be accessible by anything other than things internal to the class so it should be tested only by way of things internal to the class.
Member 4487083 wrote: Dead code is potentially a bug waiting to happen IMHO
I agree completely.
Member 4487083 wrote: it may be worth making a few modifications for testing
I agree almost completely. Testability is something that can/should be built in so that no modifications are required to do it. The connection string is a good example. Ideally those should be built to be configurable from the beginning - it shouldn't have to be added on later just to accommodate testing. Still, this is something completely different from changing the accessibility level of members to facilitate testing. Making something configurable is an enhancement that promotes flexibility and testability; making something unnecessarily public makes it more testable but introduces security risks. More to the point, making a connecting string configurable doesn't change the contract of the class but changing something from private to public does.

Hi,
I've an application which crashes inside InitializeComponent() method. It works on most of the computers but crashes on certain computers. If you need I can post the code of my InitializeComponent() method.
Any ideas?
Thanks.

How do you load images into the Picture boxes that you are using?
For a correct approach, have a look here.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

Thank you for your answer, but according to the link you've given I am doing it correctly.

Hi,
every WinForm app should have a try-catch around its Application.Run() statement; it would provide a safety net for all mishaps that could occur in the main form's construction. So try it like this:
public static void Main() {
try {
...
Application.Run(new Form1());
} catch(Exception exc) {
Console.WriteLine(exc.ToString());
}
}
That should give you the stack trace and point you straight at the problem.

Hello every body,
I've developed a .NET C# application. I have a strang problem here, Some times while working in the application It stops suddenly with no error messages or any thing. I remember when I was in the debug mode , it did the same problem also and without error messages or exceptions.I cant recognize the time it stops (may be it is not fixed ?). The program do alot of things, it's mainly for scoreboards control but it uses .Net libraries for capturing videos from TV card, access a shared folder in the network and uses custome made controls (buttons ).
How can I know the reason of this problem ???All You Need Is A Good Friend

Goto to the Debug menu, open the Exceptions box and select all options in the "Break when an exception is" dialog.
Maybe that will allow you to see an error message in the application.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

How can I convert the IPictureObject of MODI.Image.Picture to a "standard"
image (System.Drawing.Image or System.Drawing.Bitmap) in C#
thanks to allHAVE A GOOD TIME
|
|
|
|

Although I have never used IPictureObject, I can suggest if you can get the handle of the image, you can use Image.FromHBitmap method to convert it to an image object.
Hope this helps."No matter how many fish in the sea; it will be so empty without me." - From song "Without me" by Eminem

Hi,
can any one please do et me know if we could insert an image into an xml if so please do let me know how.
my task is to read an image from .xml file and save it in to databae
|
|
|
|
|
Here is way to write images to an XML file:
Image image = Image.FromFile(@"image file path");
MemoryStream memStream = new MemoryStream();
image.Save(memStream, image.RawFormat);
byte[] array = memStream.ToArray();
string imageString = Convert.ToBase64String(array);
Now all you have to do is to write this string to the XML file.
In order to read the image from the string, you can use this:
string imageString = "read the image string from XML file";
byte[] imageBytes = Convert.FromBase64String(imageString);
MemoryStream memStream = new MemoryStream(imageBytes);
Image image = Image.FromStream(memStream);
Although, it would be better if you store image files at a location and just the path in the XML files. In case you are dealing with large images, you would have a very bulky XML file."No matter how many fish in the sea; it will be so empty without me." - From song "Without me" by Eminem

Hi Dinesh,
can i know how to insert an image in an xml file sice xml file consists of only tags can you please do send me the sample link if any to my mail so that i can make samples of it

He showedspoonfed you how to turn the image into an "xml-clean" string, surely you know how to insert a string into an xml file, otherwise how can you be using an xml file at all?

I'm creating a series of controls that I need to draw myself.
They are all derived from Control and each overrides OnPaint().
The main parent control paints itself fine. It maintains a list of the second-level controls and they paint fine too. Each of these second-level controls contain their own lists of third-level controls, that ideally will draw themselves too but at the moment, OnPaint(), does not get called for them.
Seems strange that the other two classes are able to paint and this last one is not.

Forgive my newbie question. I am trying to learn C#. I have utterly confused myself in trying to restart a server console. I do not have the server start on this yet but it locks up every time I restart and I am not real sure way. It shutsdown ok but then never makes the check if the process has exited. Can anyone give me a nudge in the right direction? Thanks
public void restartserver(string serverrs, string serverloc)
{
Process p = Process.GetCurrentProcess();
Process[] servername = Process.GetProcessesByName(serverrs);
IntPtr serverHandle = FindWindow(null, serverloc);
if (serverHandle == IntPtr.Zero)
{
if (serverrs == "arcemu-world")
{
btnWorldStatus.Text = "World Server is not running";
}
else
{
btnLogonStatus.Text = "Logon Server is not running";
}
}
else
{
SetForegroundWindow(serverHandle);
SendKeys.SendWait("Shutdown{ENTER}");
FreeConsole();
bool mytrue = true;
while (mytrue)
{
if (p.HasExited)
{
mytrue = false;
if (serverrs == "arcemu-world")
{
btnWorldStatus.Text = "Closing....";
}
else
{
btnLogonStatus.Text = "Closing....";
}
}
}
}
}

Thanks for your help. After taking a look at the information provided I got it.

Is it spinning inside the while loop while (mytrue)? Also how did you verify the server has shutdown?
