i need to check if a folder exists in a particular location,if not then create that folder and save the appropriate file there.How can i acheive this using X++.
Please advice.
To check folder existence you can use WinApi::pathExists,
to create one WinApi::createDirectory or WinApi::createDirectoryPath:
str path = 'C:\\tmp\\aFolder';
;
if (!WinApi::pathExists(path))
{
WinApi::createDirectoryPath(path);
}
I have no idea what is meant by "the appropriate file", but have a look at the TextIO, BinaryIO or the other *IO classes.

I am using UIDocument to save a document file to the local storage sandbox in the Documents directory. I have another file in iCloud with the same name. How would I check if those two files are copies of the same document file or two different document files with the same name?
Using NSFileVersion doesn't tell me if they are the same file, just what version of the file it is.
I tried getting the resource values of the files, but the file in the local storage sandbox gives me nil as the document identifier.
Here is code using the documentIdentifier resource value:
let localFileResourceValues = try? self.document!.fileURL.resourceValues(forKeys: [URLResourceKey.documentIdentifierKey])
let iCloudFileResourceValues = try? destinationURL.resourceValues(forKeys: [URLResourceKey.documentIdentifierKey])
print("documentIdentifier", localFileResourceValues?.documentIdentifier as Any, iCloudFileResourceValues?.documentIdentifier as Any, localFileResourceValues?.documentIdentifier == iCloudFileResourceValues?.documentIdentifier)
Print results:
documentIdentifier nil Optional(133819) false
Is it possible to get an NSMetadataItem from a file in the local storage sandbox?
I would appreciate any help.
To find out if the two file paths point to the same file object, you need to normalise the file paths by using NSString stringByStandardizingPath, then resolve symbolic links by using NSString stringByResolvingSymlinksInPath:, and then compare the paths. This web page has a good description and ready-to-go code.
To find out whether two files have the same contents, even while they might be different file objects, then NSFileManager contentsEqualAtPath:andPath: is useful.
I am customizing the default build process template in TFS 2010.
i am using "DownloadFiles" build activity and in server path i have given "$/TFS/Libraries/Foo.DLL", when i run the execute definition its throwing error as "Access to the path '\ServerName\SharedFolder\BuildName\TempFolder' is denied.".
But when i give server path as "$/TFS/Libraries" its downloading all the files in Libraries folder into shared TempFolder.
But i need do download only one file. Please help..
Thanks in advance..
Now, DownloadFiles does work for a whole folder only:
ServerPath="$/proj/path" - works great, all is downloaded to LocalPath.
ServerPath="$/proj/path/name.ext" - borked.
I've de-compiled DownloadFiles to see why: First it gets a list of server items, in our case just $/proj/path/name.ext. Then, it calculates the local path like this:
localItemPath = Path.Combine(LocalPath,VersionControlPath.MakeRelative(ServerItem, ServerPath));
In this line, the activity assumes that ServerPath is a path. If it's not, then MakeRelative will not recognize it, and the local path will be LocalPath/$/proj/path/name.ext, as the OP has observed.
Also, if ServerPath is not canonical - for example, $/proj/path/../path2, the same will happen. Solution: use VersionControlPath.GetFullPath(myNonCanonicalPath).
You need to grant the user running the build service with write permissions on the shared folder.

There are two separate Build activities, DownloadFiles for a folder ServerItem and a DownloadFile for a single file ServerItem.I'd expect it should work with DownloadFile.
In my Hadoop Map Reduce application I have one input file.I want that when I execute the jar of my application, then the input file will automatically be called.To do this I code one class to specify the input,output and file itself but from where I am calling the file, there I want to specify the file path. To do that I have used this code:
QueriesTest.class.getResourceAsStream("/src/main/resources/test")
but it is not working (cannot read the input file from the generated jar)
so I have used this one
URL url = this.getClass().getResource("/src/main/resources/test") here I am getting the problem of URL. So please help me out. I am using Hadoop 0.21.
I'm not sure what you want to tell us with your resource loading, but the usual way to add an input file is this:
Configuration conf = new Configuration();
Job job = new Job(conf);
Path in = new Path("YOUR_PATH_IN_HDFS");
FileInputFormat.addInputPath(job, in);
job.setInputFormatClass(TextInputFormat.class); // could be a sequencefile also
// set the other stuff
job.waitForCompletion(true);
Make sure your file resides in HDFS then.
How can I programmatically add files to a TFS project that have code behind files. I can say the following to add files. That will only add single files to a project and not the file plus the code behind file. I'm trying to add a resource file and it's code behind that were dynamically generated to a TFS project.
workspace.PendAdd(filesWithPathToEdit, true);
I had to put it in a T4 template to get access to the current Visual Studio DTE otherwise it would randomly work if I tried it outside of a t4. You can use the DTE to get a list of projects from a solution then add a ProjectItem and it contains ProjectItems so you can add your code behind there. ResxContainer is a custom class to just contain all information about my resx file i needed.
EnvDTE.DTE dte = (EnvDTE.DTE)HostServiceProvider.GetService(typeof(EnvDTE.DTE));
//dte = (EnvDTE.DTE) hostServiceProvider.GetService(typeof(EnvDTE.DTE));
//dte = (EnvDTE80.DTE2)Marshal.GetActiveObject("VisualStudio.DTE");
Projects projects = dte.Solution.Projects;
if (projects.Count > 0)
{
IEnumerator enumer = ((IEnumerable)projects).GetEnumerator();
while (enumer.MoveNext())
{
Project proj = (Project)enumer.Current;
if (proj.Name == projectName)
{
foreach (ResxContainer res in items)
{
ProjectItem item = proj.ProjectItems.AddFromFile(res.ResxPath);
item.ProjectItems.AddFromFile(res.CodeBehindPath);
}
}
}
There's no way for it to automatically know if a file depends on another. However, you can decide on your own which files will typically have a code behind file associated with them and add them yourself.
For example:
If you begin to add a file with an .aspx extension, then those files, as we know, typically have a code behind file. That code behind file, we can assume, has the same file name, with .cs appended. So, if we have "Default.aspx", then we can safely assume that there will be a "Default.aspx.cs" and that they are dependent on each other, so we should add both.
The same thing goes with .xaml and .xaml.cs files.
My files are referenced like so (it's all relative):
// WHERE YOU KEEP THE PAGE TITLE XML
public static string myPageTitleXML = "xml/pagetitles.xml";
and
using (StreamReader r = new StreamReader(myPageTitleXML))
{ //etc.. . .etc....etc..
}
I get system.io.directorynotfound, and "this problem needs to be shut down", when I double click the executable. But running it from the console works like a charm. What's wrong here?
I played around with attempting to set Environment.CurrentDirectory but couldn't get anything to work. Why should I have to do that anyway? It defeats the purpose of a relative path no?
responding.. .
"application" does not exist in the current context, i'll keep trying what people have mentioned, this is not a windows.form
testing
Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase), myPageTitleXML); gives error URI formats are not supported, as does Path.GetFullPath(). Server.MapPath results in an error as well, this is currently offline
Well assuming this directory is somewhere under the directory in which your code is executing, it sounds like you can use ..
Application.ExecutablePath()
or
Application.StartUpPath()
.. to get an idea as to what your application is seeing when it goes in search of an 'xml' directory with the 'pagetitles.xml' file in it.
If the directory returned by one of these methods does not point where you thought it did, you'll need to move the location of your application or the location of this folder so that it is within the same directory as the app.
Hope this gets you on the right path.
So, when you run it from double clicking the executable, is there a file named pagetitles.xml in a folder named xml, where xml is a folder in the same location as the executable?
It's certainly possible to use relative paths like this, but I wouldn't really recommend it. Instead, maybe use something like:
string fileToOpen = System.IO.Path.Combine(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase), myPageTitleXML);
using (StreamReader r = new StreamReader(fileToOpen))
{
//etc.. . .etc....etc..
}
Is this ASP.NET code? If so then you probably need to do MapPath("xml/pagetitles.xml")
