Sometimes (normally) none but not always. It depends on how the author of the object in question chose to implement it.
== is an overloadable comparison operator that is normally implemented something like this (note != would also HAVE to be implemented).
public static bool operator ==(MyObject myObjectA, MyObject myObjectB)
{
return (myObjectA.value == myObjectB.value);
}
Equals is an overridable method, and most Objects also implement IEquatable<objecttype> so the implementation is normaly something like this.
public override bool Equals(object obj)
{
if (obj is MyObject)
return Equals((MyObject)obj);
return false;
}
public bool Equals(MyObject other)
{
return this.value == other.value;
}
Notice this example implements the == operator in the Equals method but it is not a requirement. It could test a totally different property or variable, if it's at the same location in memory (i.e. is the same object and not just the same value) or anything else.
Conclusion: You should check the documentation and/or experiment to see how they're evaluated. The object browser will often give hints when exploring the object. Reflector (google for it) can also be very useful as you can view the source to figure out what's going on if the assembly is not obsuficated.

Hey everybody!
How do I reference different DLLs in release and debug?
Thanks!
|
|
|
|

Release or debug shouldn't matter. To add a reference to a dll (more easily done with a .NET dll), simply look for the references folder under the main solution for the project and right-click the references folder and then Add Reference. You will be asked for the location of the specific dll file.

It does matter.
In case in my solution I have several projects (one exe and many DLLs), and the EXE is referencing the DLLs.
When I'm compiling as debug I want to reference the Debug output of the DLLs, and when I am compiling release I want to reference the Release output.

You should use a project reference, that will automatically use the output of the current configuration.
If you want to reference a debug/release version of a DLL that's NOT part of your solution (so you cannot simply use a project reference), then edit the .csproj file with a text editor, look for the reference and replace "Debug" in its HintPath with "$(Configuration)".

hi eveybody, i have a problem, sorry about my english.
when i trying to request for youtube video which i want to download by segments (for that i use addrange), the addrange method doesnt work.
if i try to download from other servers (other downloads) the segments idea work fine, it splits the download with addrange method to parts.
but for some reason from youtube it start from the begining until the file is complete downloaded, and not split the file to segments with "addrange". i think because the server send me an http respone of UDP. but i dont sure. i saw many downloaders who succeed download youtube videos with segments.
maybe someone here knows the problem and can help me.
thnx asaf. =]
my code:
HttpWebRequest REQ = (HttpWebRequest)WebRequest.Create(url);
REQ.AddRange((int)pos, (int)poscount);
HttpWebResponse RES = (HttpWebResponse)REQ.GetResponse();
Stream input = RES.GetResponseStream();
FileStream output = new FileStream(@"c:\temp" + f, FileMode.CreateNew);
byte[] buffer = new byte[RES.ContentLength];
int B;
while ((B = input.Read(buffer, 0, buffer.Length)) > 0)
{
output.Write(buffer, 0, B);
}
output.Close();

The only HTML tag that exists is the <marquee> tag; take a look here for more info, although I would highly discourage use of it as its never been compatible with all browsers (only IE-based but I tried and it worked in Opera so perhaps other browsers started to include it when it started to become obsolete).
I'd recommend looking for a JavaScript ticker/marquee; something like this might help.

Hi All
I have two panel in my form, my 1st panel contains 3 buttons and the 2nd has 2 buttons, 3 textboxes and a label.
I need to get all of these controls to save their settings into a file, I tried:
foreach (Control ctrl in this.Controls)
MyFile.ReadLine(ctrl.Text);
But "this" has only two controls (My two panels) and I can't see the other controls contained in panels.
I know I can use the foreach statement for each of my panels but if I have a panel in panel2? Do you have any idea to solve this using only one loop?
Regards.
While (true) { Human.isLearnable = true; }

|

Each Panel has a Controls property, no?
|
|
|
|
|
Yes it has but I don't want to have a foreach statement per panel.
Thanks
While (true) { Human.isLearnable = true; }

Well then, just find something else to do with your time. If it's not freakin' obvious what you have to do, and that "not wanting to" isn't a viable tack if you want to accomplish your goal, you shouldn't be a programmer. I bet you could find a job sweeping standing water off of sidewalks. Oh wait, that requires a little effort as well.
Oh wait! Try just staring off into space. That should keep your feeble excuse for a brain busy.

You can use something like this:
foreach (Form frm in Application.OpenForms)
{
foreach (Control ctrl in frm.Controls)
MessageBox.Show(ctrl.Text);
}
This contains two foreach statement but indepedent of how many forms you have, you can get their controls.

You're right, but I have only one form, my form contains two Panels and each Panels contains some Controls.
Your foreach statements give me my Panels only.
Thanks
While (true) { Human.isLearnable = true; }

Use two foreach statements. Like this:
foreach (Control oCtrl in this.Controls){
// Do something
foreach(Control oCtrl1 in oCtrl.Controls){
// Do something
}
}

It's possible only for two panels.
I wont be glad if i have 3 panels in my form and each one contains 4 panels inside... 
however thanks.

In that case you can use conditional recursion by checking if current control has child controls.

Yeah, that's how I'd do it.

You guys are wasting your time. He probably thinks "recursion" is having to visit the toilet more than once in a 60-second time frame.

Each 'container' has it's own control collection so you have to loop each one of them. The most easiest way is to create a method for listing controls and call this method recursively passing the collection (for example List) as a parameter.
Pseudo-code would be something like:
GetControls(List controlList, Control parent) {
foreach (Control ctrl in parent.Controls) {
controlList.Add(ctrl);
GetControls(controlList, ctrl);
}
}
The need to optimize rises from a bad design
