Unable to refer to jpg in bitmap path parameter - c#

I have a jpg in a folder in my project. I want to make a bitmap out of it but it says my path is invalid when I try to refer to the jpg.
https://i.stack.imgur.com/dAWIG.jpg
Console Exception:

The reason is by default console application points to the bin/debug folder.So you need to go up two level to get the file
#"../../image/<Your File name>"

URI-Formatter not supported in Directory.SetCurrentDirectory()

I'm working on a legacy project, and through debugging and re-engineering i stumbled upon the following error.
The documents are send to the location http://localhost:8080/Files
In the existing application it is handled like this
1 var path = Export.Path; <- in Debug it is `http://localhost:8080/Files`
2 Directory.SetCurrentDirectory(path);
At Line 2 the following Exception is thrown:
System.ArgumentException

File is being used Exception at Directory.Delete with the folder's path in the message

Hi I'm running the following code:
void bar()
{
var dirInfo = new DirectoryInfo("C:\foo\folder");
dirInfo.Delete();
}
And at one point I got the following exception:
System.IO.IOException: The process cannot access the file 'C:\foo\folder' because it is being used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive)
at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive)
at bar()
Two things bother me here:
I called DirectoryInfo's Delete(). Why did I get Directory's Delete() in the stack trace without DirectoryInfo's one?
How come the file that is being used has the same path as my folder? Is this an error in the message? Or was there a different error?
To answer the first of your questions, DirectoryInfo.Delete calls Directory.Delete. If you're running in release mode, it's possible the compiler has optimised your code and you're just seeing the underlying call.
Edit: I've just done some tests in VS2013. When my project was a release build compiled for Any CPU I could see the call to DirectoryInfo.Delete before the call to Directory.Delete in the stack trace:
StackTrace:
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive, Boolean throwOnTopLevelDirectoryNotFound)
at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive, Boolean checkHost)
at System.IO.DirectoryInfo.Delete()
at test.Program.Main(String[] args) in c:\Projects\test\Program.cs:line 21
but when I compiled a release build for x64 it showed only the call to Directory.Delete:
StackTrace:
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive, Boolean throwOnTopLevelDirectoryNotFound)
at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive, Boolean checkHost)
at test.Program.Main(String[] args) in c:\Projects\test\Program.cs:line 22
It does look like some optimisation is going on (incidentally, the code was unchanged between tests - I'm guessing the change in line number is also related somehow to compiler optimisation).
Have a look at this question - directoryinfo delete vs directory delete
To answer your other question - did you have a file in the directory open in another app? There are many reasons why another process may be doing something to that folder.

How to convert *.jar that contains native call to a DLL(Mono C#)

We're using IKVM to convert our *.jar to dll that we using to migrate our code to C# with Mono..
We have a problem especially when working with jar contains a JNI call, expl JnativeHook, its make an error when we try to convert it using IKVM, i have reported the error to the author as the follow:
I'm trying to use JnativeHook.jar library, its work for my java apllications, However:
Not: JnativeHook its a cross-platform containes 3 .dll depends on the OS when the java application is running (dynamic loading of *.dll)...
JnativeHook.jar containes also a package(demo) that containes a main classe, i have solved this problem by deleting this one, now i'm sure that will be converted to dll...
finally, when i try to convert this one to .dll i get this error:

The response from the author:

Message:
Thanks. Fixed in cvs. BTW, the error is because ikvmc can't write to
JNativeHook.dll (probably because you don't have write access to the
directory).
As you can see the author has respond with a few words without giving us a solution..
What i understand is the embedded Dll make the error, in fact IKVM does not know how to work with it(inside the JAR)...
there is some suggestions to solve this problem?
PS: what does mean Fixed in cvs ?
Thank you.
The cause of the problem is that you have no write rights to the output location. Run the command on another location with write rights.
I think the fix will only prevent the "INTERNAL COMPILER ERROR" message.

Both the source and destination directories exist.
You have colons (:) in the destination path, which Windows does not allow (apart from as part of the drive letter specifier, of course...).
To get this to work, pick a different date format for the date-time you are trying to embed, which does not use colons.
Here is a MSDN site which will explain reserved characters as well as what is allowed or not allowed when creating Windows File Paths
replace the ":" with underscores if you have to "_" reformat the date portion as well to use yyyymmdd, or mmddyyyy stored in a different DateTime variable and convert that to a String.. there are many other options you can use..

'No Source Available' Error

I copied my project to a dsik on key and tried to run it in my mother home pc.
In my code im using HtmlAgilityPack.HtmlWeb and i have this line:
private List<string> test(string url, int levels,DoWorkEventArgs eve)
{
levels = 0;
HtmlWeb hw = new HtmlWeb();
If i run my program it will not throw any exception but will continue just will not do anything.
If i put a breakpoint on the line: HtmlWEb hw = new HtmlWeb();
Im moving to a No Source Available window:
Locating source for 'D:\Source\htmlagilitypack.new\Trunk\HtmlAgilityPack\HtmlWeb.cs'. Checksum: MD5 {58 c1 63 f6 cd 5 65 de 4c 3c d5 4b b1 b7 7 48}
The file 'D:\Source\htmlagilitypack.new\Trunk\HtmlAgilityPack\HtmlWeb.cs' does not exist.
Looking in script documents for 'D:\Source\htmlagilitypack.new\Trunk\HtmlAgilityPack\HtmlWeb.cs'...
Looking in the projects for 'D:\Source\htmlagilitypack.new\Trunk\HtmlAgilityPack\HtmlWeb.cs'.
The file was not found in a project.
I see that HtmlWeb.cs is missing in some directory on D:\
I have also a try and catch in my function test if i put a breakpoint on the catch i see:
IOexception was caught.
The device is not ready.
My guess that its looking for a file maybe HtmlWeb.cs in D:\
And in my mother pc D:\ is a DVD drive in my pc its hard disk.
The full exception:
System.IO.IOException was caught
Message=The device is not ready.

InnerException:
I dont see any problems in my code in the reference area with the HtmlAgilityPack.dllim
Its not missing.
So i wonder why its looking for a file on D:\ ?
If on my pc i did rebuild/build solution and saved it all i was sure its adding all the files and dll's it needs to the project so if i copy it to my disk on key and run it on my mother pc it will work.
So what did i do wrong here ? And how should i fix/repair it ?
I erased the HtmlAgilityPack.pdb and it worked just fine. Erase the file, rebuild, close and reopen and see if it works
