ok, so I have this....
private void Form1_Load(object sender, System.EventArgs e)
{
Process [] localByName = System.Diagnostics.Process.GetProcessesByName("notepad.exe");
}
So, first things first. From what I understand, the variable localByName (assuming it is a varible, and if it is what kind?) is storing the data from what ever "GetProcessesByName" returns, correct? If so what kind of data is it returing? A sting? A bool?

It is a variable and it is returning an array of Process objects.
You can access a Process object from the array like this:
Process p = localByName[0];
You can loop through the array like this
for(int i=0;i<localByName.GetLowerBound(0);i++)
{
}

hi,
how can i dequeue object from a Queue when the elements type of the queue is a structer?
for example, i use the following code to Enqueue the object 'new_object' which type is ABCD :
ABCD new_object=new ABCD();
MyQueue.Enqueue (new_object);
how to Dequeue?
this method doesn't work:
ABCD another_object=new ABCD();
another_object=MyQueue.Dequeue ();
any help?

MyQueue.Dequeue ();
Dequeue() returns an object, so you need to cast back to the original object type.
another_object = (ABCD) MyQueue.Dequeue();

Can you tell me how to create a completely hidden windows form. I'm using it just for its message pump. I best I can do at the moment is hide from view, taskbar but no the Alt-Tab menu. And the user can still close it when it has focus and using Alt-F4.
I'm using a hidden form as I want to pass data using BeginInvoke between threads.
|
|
|
|
|
Well, have you thought of setting the forms visible property to false before calling its show method?
|
|
|
|
|
That doesn't work! Calling show just set visible back to true. Also the form still shows up in the taskbar and Alt-Tab menu. Instead I'm just using a Control instead of a Form.
|
|
|
|
|
I'm not sure exactly what you are trying to do, however, do you need to call Show? just instantiate the form, then do what you need.

I have a problem .. One of my applications is loading DLLs into memory but isnt unloading it.
I want to wirte a program that will get the address of a particular DLL loaded into memory and then unload it...Any ideas ?? Is it possible

By DLLs are you meaning .NET Assemblies or are you meaning C/C++ DLLs?
Once .NET Assemblies are loaded into an AppDomain they cannot then be unloaded unless you unload the entire AppDomain. Not sure what you can do if it is a C/C++ DLL, you could try calling FreeLibrary but there might be hidden functionality relying on that DLL still being loaded.

I have a COM object that returns a binary string in a BSTR. .NET marshals this to a string. The problem is that some of the bytes get dropped when this happens.
As an example, load a PFD file into a byte array. Convert the byte array to a string, and then convert the string back to a byte array (UTF-8). If you compare the two byte arrays, they aren't the same.
I probably haven't explaied this very well, but I hope I haven't made it too confusing. Has anyone had any experience with this, and what can I do to make it work?
Thanks.

Do you mean PDF file? If so what has loading the file got to do with COM? I have written quite a bit of code moving, loading PDFs etc. And I do it as Streams and byte arrays and have yet to see a problem.
Perhaps if you explain in more detail I may be able to help.
|

The COM object creates the PDF file on the fly. It's a third party control, so there isn't too much we can do about it.
I think my example of loading and manipulating a PDF file isn't the best example, because it doesn't really simulate the problem.
However, just out of curiousity, is there anything wrong with the following code:
<br />
pdfFile.Read(pdfBytes, 0, length)<br />
<br />
string pdfString = Encoding.UTF8.GetString(pdfBytes);<br />
<br />
string pdfBytes2 = Encoding.Unicode.GetBytes(pdfString);<br />
At this point, pdfBytes and pdfBytes2 should be the same, correct? This is not the behavior I'm seeing. I'm new to C#, and probably have made a very obvious mistake, but I would really appreciate someone pointing it out to me.

Hmmm, not sure why the behaviour would be like that. I never have to convert the byte array in a string. I just carry it around till I have to write it out. I am not sure what happens behind the scene when the byte array is converted to a string. Maybe some stuff does not convert. What if you create a byte array with simple text or numbers and try the same. If that works then maybe its something in the PDF that does not convert well to a string. Just guessing. Sorry could not be of more help.

The interop part of marshaling the BSTR to a string was working ok. The problem was with the conversion from a Unicode array to a byte array. The correct converstion is:
<br />
byte[] pdfBytes = Encoding.Convert(Encoding.Unicode, Encoding.Default,<br />
Encoding.Unicode.GetBytes(pdfString));<br />
What I had been trying to convert to UTF-8, which was what was causing the problems. Converting to Default solved the problem.
Thanks for all the comments.

I'm currently converting some Java code to C# and
if have problems converting this:
Java:
public class MySuperClass {
String generateShowMe() {
return "ShowMe from MySuperClass";
}
public void ShowMe() {
System.out.println(generateShowMe());
}
}
public class MyChildClass extends MySuperClass {
String generateShowMe() {
return "ShowMe from MyChildClass";
}
public void ShowMe() {
super.ShowMe();
}
}
When i call MySuperClass.ShowMe() i get of course
"ShowMe from MySuperClass", but when i call
MyChildClass.ShowMe(), i get "ShowMe from MyChildClass".
-> although the child class calls the base (super) class to show the string, the super class calls generateShowMe() from the child class.
How can i to this in C#?
(i currently simulate this, by using a delegate to call generateShowMe())
thanks,
Carsten

I think you mean

obsolete - don't won't to blame my self
see Richard Deeming post for a working sample.

Could be something to do with the fact that MyChildClass.generateShowMe returns "ShowMe from MySuperClass" instead of "ShowMe from MyChildClass".
