I have method to which object of Type ICollection is getting passed.
I want to create an object of List<> (Generic List) , with object of ICollection. Is that possible?

You can use the ICollection interface to iterate over the collection, and then put the items into a List, or whatever.

thanks, but i don't want to iterate, is that direct way, like while creating ArrayList object we can directly pass ICollection object to the constructor of ArrayList so that the contents of ICollection get copied to Arraylist object, is something like possible with generic List (List<>) object?

I don't think so, not if the ICollection is not templated. because, the difference is, an ArrayList and an ICollection both knew they were just holding objects.

Hi,
let me explain what i want to do.
I'd like to store properties into a LinkedList (or something similar (key, value pairs)) and then
change the control property via changing the value in this list:
something like this:
Form myForm = new Form();
LinkedList<somekeyvalueclass> list = new LinkedList<somekeyvalueclass>();
list.AddLast("width", myForm.Width);
and then by changing this property i change myForm.Width:
findPropertyByName("width").value = 500;
Maybe I'm completely wrong and it cannot be done in C# 
|

Is there a reason you're doing it like this? Besides, the 500 you store in the list is different from myForm.Width.
Why don't you just do myForm.Width = 500;?
Cheers,
Vikram.

Yes i know it's different and that's what i'm asking, if there is a way howto store some kind of reference to that object...
(it's kind of setup, i'd like to register properties which should be changed in certain circumstances and change them on one place)
|

Well, you could store the settings in a settings file and change the value there. That's how lots of programs do it.
Deja View - the feeling that you've seen this post before.

|
|
Yes it is possible to do it this way, but what i intend to do is, change those settings also at runtime not only at startup (restore to defaults)...
|
|
|
|
|
Once you've stored the values in a config file, you can read them (and update them) any time you want. Am I missing something?
Cheers,
Vikram.

Yes, it can be done (with a bit of reflection and a class to manage the work).
That doesnt necessarily make it a good idea! Store your settings wherever you want (DB, file, Xml or wherever) and have a process that reads those settings and sets the screen.

Could you please show me an example
|
|
|
|
|
try exploring Hashtable or Dictionary generic?
|
|
|
|
|
I have some code which looks like that:
[DefaultValue(CornerStyle.Rounded)]
public CornerStyle RectCornerMode
{
get { return this["RectCornerMode"].GetValue<CornerStyle>(); }
set { this["RectCornerMode"].SetValue<CornerStyle>(value); }
}
in this[string] I get the attribute decorating the calling method, and used it to compute a default value.
now it seems that sometimes (when build in release mode) the property is by passed and the calling method call this[string] and GetValue directly, thus ignoring the decorating attribute....
is there a way to avoid this inlining?
any suggestion?

found it: MethodImplAttribute.
Anyway I thought of a better solution...

Basically, if you render a link, that link should contain stuff on the URL that actives the account. Is the problem with writing that code, or is the problem getting the link to work ?

Do you mean you are not able to generate the link or not able to update when user clcks on that link ?

Hi
I am working on Biomatric Solution Project.I am using SecuGen BSP Device for This purpose.Device return Fingure image data in string .I want to display this Fingure image into Picture Box Control. For This I kept The output string in Byte array and then i write it in Memory Stream and at last
create a bitmap to display image(at this stage i got error "Parameter is Not Valid")
Problem:-Code Give error when i create a bitmap to display image.
red line show the error point.The error syntax is "Parameter is Not Valid".
My Code is:-
try
{
//Create Device API Interface object
SECUBSPCOMLib.APIInterface objSecuBSP = new SECUBSPCOMLib.APIInterface();
long deviceID;
objSecuBSP.EnumerateDevice();
//Open Device
objSecuBSP.OpenDevice(2);
string szFIRTextData;
objSecuBSP.Enroll(null);
//Get Data of Image(Fingure Print) into a string
szFIRTextData = objSecuBSP.FIRTextData;
//Get string into Stream Format means into Byte array from string
byte[] arrBytes = new byte[szFIRTextData.Length];
int i = 0;
foreach (char c in szFIRTextData.ToCharArray())
{
arrBytes[i] = (byte)c;
i++;
}
// Open a stream for the image and write the bytes into it
System.IO.MemoryStream memStream = new System.IO.MemoryStream(arrBytes, true);
memStream.Write(arrBytes, 0, arrBytes.Length);
// Create a bitmap from the stream for Display it on Picture Box Control
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(memStream);
pictureBox1.Image = bmp;
memStream.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

Are you sure this stream contains a bitmap ? I'd have thought passing it as a string would cause it to null terminate in the wrong spot.

Wahoo!
I just did my first little Application that is of any use. Its a calculator that my friend uses for work, with some weird Calculations in it. But it works.
Anyway, I suppose I have 2 questions.
1. Is there a way to make just 1 Setup.exe file that can be sent without any other files that will install fine at the other end.
2. If not, Which files from the publish directory do I have to send to get the Application to work at the other end?
Many Thanks all
Tony

1 - not in C#, you also need the .NET framework
2 - yuo probably just need the exe and the manifest. Plus the framework.

Tony, just send an .exe file if it is not having any dependancy dll file.
