please do not remove a message that has replies; it should not be possible to do so but it is, and it is against the forum guidelines.
Now return to your book and pay special attention when you reach 'D'.

You didn't remove it by mistake, it took a conscious and deliberate act on your part. You were more than likely trying to save yourself embarrassment from posting such an obvious question

Hello
I embedded an resource "WINGDNG2.TTF" with vs2010.
Now I'm not able to access to that resource.
I try to access to it whith
"assemblyname.WINGDNG2.TTF"
or "mynamespace.WINGDNG2.TTF"
or "WINGDNG2.TTF"
but alway I have resource file not found.
I don't know whats wrong. Mybe because my namespace has an dot (.) ?
Thank you.

Yes, it is still confusing me when to use namespace/assembly name while accessing resources. Somethimes neither is required:
string resourceName="resources.myapp.ico";
icon=new Icon(type, resourceName);
works for me, when the icon file "myapp.ico" is located in the project's "resources" folder.
No namespace, no assemblyname involved.

That is a Java question; launching an app does not depend on the language of the callee. All it takes is to use Google and find some documentation[^].

I am working on a text editor application and I would like a status strip on the bottom of the window but I cannot see the last line of the text box because the strip overlaps it. And if I set the docking of the text box to top I can set the size so it will not overlap but then it will not stretch vertical with the window. How can I set the text box to stretch with the window but not overlap the status strip?

Set dock to fill on the textbox and then right click the textbox control and click bring to front.

Hello All
Am developing a MultiThreading Application and I have searched the internet for guide lines how to write a thread safe methods.
I found some conflicts and I would like if any of you help me to figure out the correct solution.
Below is Example of a Method That I need you to Evaluate if it is thread safe or not and Why.
public static int Search(string xml, char item)
{
return xml.IndexOf(item);
}
|
|
|
|
|
Well calling IndexOf will invariably run through a loop at some point looking for item
Is this thread safe?
public static int Search(string xml, char item)
{
for(int i=0; i<xml.Length; i++)
{
if(xml[i] == item)
return i;
}
return -1;
}
EDIT:  As others have said strings are of course, immutable. I deserve a kick for that one.

IMO everything you said was correct, however it did not provide an answer, it merely rephrased the question.
I will not provide a kick you say you deserved.

I but I was trying to point out that if the string changed while your where looping you would have a problem. But of course in c# when you pass a string it's a whole new object. Been working with C++ for too long now it seems, where everything has pointers or pointers to pointers. In one case a had a pointer to a pointer to a pointer, pointy.

Now that deserves a kick. A string parameter is not a new object, in fact it is a pointer (they like to call it a reference), just as it is in C/C++/Java. However it points to an immutable object, something the compiler will not allow you to modify, only replace.

Indeed, right you are. Glad too see I'm earning my Kicks.
I know that (almost) everything is passed by reference so you get the actual string but anybody who modifies or replaces it is then pointing to a new object, leaving the old one intact until GC will eventually devour its soul, right?

yes, that method is thread-safe: its results only depend on input parameters, and both string and char are immutable, so there is nothing that can disturb the method; also the method is not changing the outside world, so it isn't disturbing anything itself.
As soon as you start referring to other data, such as class members, things may change though.

As you aren't operating on a member variable in this example, and you have a nice self contained method where you have immutable data, this is perfectly thread safe. In other words, there is no chance that another thread can change the value of xml or item and affect the outcome.
Suppose that you changed it so that xml was a member property of type XMLElement, and you passed item in - then you could have a none thread-safe method because you could affect XMLElement before you actually performed the operation on the XML.

Not if you change the string with unsafe code.
Otherwise the result will of course be correct for the (old) value of the xml parameter, but not necessarily for "something else" (I mean, if you passed in this.Xml or something like that, the result (when it is returned) may have nothing to do with the current value of that field)

Some articles say that if you pass variables to your method that are not immutable or reference variable this may make the method not Thread Safe.
Does any one has more details about this point if it is correct or wrong and why?

Hey
My program recieves a byte array containing a jpg. I am using Image.FromStream and then viewing the image on a picturebox. Image.FromStream is quite slow so is there any other way I could view the jpg?
Thanks
|
|
|
|
|
I don't believe there is another way. Apart from loading it from the disk (which really, opens the file then reads it from the stream)
There shouldn't really be any reason for it to go particularly slowly, unless it's a very large image. Could it be possible that something else is causing the lack of swiftness?
