I am a beginner at programing and I´m writing my second Prog.
I have a Question about how to get a relative path to my application Startup path.
The Program reads an .xml-file that has a path of a .jpg stored in it. It creates a Picturebox for every path and loads the respective image.
The problem I have is, that I have the images in my Dropbox to be able to use the Program on any PC that has Dropbox. When I use the OpenFileDialog on my main PC and save the Path of the .jpg to the xml it won´t work on my laptop because the Dropbox folder is on another drive as on my main PC.
Does anyone have an idea, how to get around this Problem?
To solve your issue, This will get the current location of your application
Directory.GetCurrentDirectory()
You can do a simple replace of the path.
Example :
String JPG_Path_Relative = openFileDialog1.FileName.Replace(Directory.GetCurrentDirectory(),"")
When the dropbox folder is in the default location (User-folder) you can use this to get your path:
string userFolderPath= Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);
This will give C:\Users\USERNAME (drive may be different).
Then simply add the rest of the path to your image folder.
string imageFolderPath = userFolderPath + #"\Dropbox\Imagefolder";

sorry first time user and currently learning c# at uni, i'm working on an assignment and i'm trying to get the file path to work on the memory stick as that's what i need to hand it in on, thanks many regards
I'm not completely sure what your question is by I think what you're talking about is absolute vs relative paths. If you use an absolute path like "C:\users\yourname\blalba\project\stuff", then it's obviously only going to only work on your computer. However, you mostly all of the time want to use relative paths. Relative paths have the root directory of the build output files for your project; where your .exe file is built for your project. This is usually in "projectdir\bin\debug" or "projectdir\bin\release". So if you put for example a file called 'test.txt' in that directory, you can simply put the relative path "test.txt" instead of "C:\users\yourname\blalba\project\bin\debug\test.txt". If you were to put 'test.txt' in the project directory, you can use the relative path "....\test.txt". "..\" means navigating one step back.
The path to the directory containing the files you are looking for is "F:\Mod005244, 1715840". The "1715840 JH" is just the name of the drive. You access different drives via the drive letter. In this case, the drive letter "F" was assigned to your flash drive.
I would suggest making the file path configurable or request input from the user of the program as the drive letter of a flash drive will not always be "F". There are even classes (such as FileBrowserDialog) that will open a graphical file browser dialog and prompt the user to navigate and select a file.
I have an Image Path which is of D: drive and I want to display that Image on my Image Control of asp.net.So, how to provide file path to Image.ImageUrl?
"D:/Folder/001_001.jpg"
I tried with server.MapPath() method but doesn't work.
If you're deploying in IIS, you could create a virtual directory Images that would point towards D:/Folder, then you could set your ImageUrl to ~/Images/001_001.jpg.jpg.
An alternative solution could be to create a symlink between the two folders. You would run something like the following in cmd mklink /D ""D:/Folder" "[YouProjectPath]/Images", then set your ImageUrl to ~/Images/001_001.jpg.jpg. I would stay away from this though as it would only work on a machine where the project lives in the exact same path as yours.
You can make local path as following "file:///D:/Folder/001_001.jpg".
However, it's strongly not recommended to use this practice even if your site is planned to stay on your local computer only and will never been deployed to real Internet. You should copy / upload the file to your site's subdirectory 'Images' and then use the relative path '~/Images/001_001.jpg'.
Hello I have a program made in Visual Studio in C#.
In this program I have some pictures that need to be called. And some html files that need to be saved.
All these files are saved in the map 'mails'.
At the moment I have the path:
String pad = #"C:\Users\Charlotte\Desktop\proof of concept\mails\";
I need this path to be relative so the user of the program can just copy the map mails to wherever he/she wants it and execute the exe of my program and just work with it.
Can anyone help me?
You can use function: Directory.GetCurrentDirectory() to get the path of current directory instead of telling program the fullpath.
If the user places a file wherever he wants, you need to tell your program where it is aomehow. So if you use OpenFile dialog your path would be:
string pad = openFileDialog1.FileName;
On the other hand if you mean that a path should be relative to your exe file you would use:
string pad = Application.StartupPath + "\\mails\\";
This will mean that a path is a directory of your exe \mails, but without a name of the file.
try it
string path = #"..\..\mails\";
i am trying to make a code which takes an image from a file path which i type in manually.
here is my code:
pieceImage = Image.FromFile(#"O:\Projects\imagename.png");
This code is saved on my USB flash drive.
However, whenever i run this code on a different computer, the path is different (obviously) and doesn't necessarily start with O:\ but something else, for example F:.
What can i use so that the path will change accordingly to the computer on which it runs? many thanks in advance.
You could get the drive letter based on the drive name, then build the Path to the file based on that (so only use the relative path from the root of the drive, no letter). See the DriveInfo class on MSDN and this question for a practical example of usage.
Of course, if the image is not on the USB drive, you will need to be more creative. But then I would recommand a different approach all the same, because there might be a design flaw in all this.
Assuming your program is in directory /Program/, include all images under your /Program/ directory, such as /Program/Images/. That way the images will be available no matter where the program is run.
i need to get the full folder path in a windows project using c#.I tried with path.getFulPath(filename).bt it returns the application path+filename.how can i get the actual path like "D:\eclipse_files\ads_data"?
A relative path such as myfile.txt is always resolved in relation to the current working directory.
In your case the current working directory seems to be D:\eclipse_files\ads_data so your relative file path gets resolved to D:\eclipse_files\ads_data\myfile.txt when you call Path.GetFullPath.
To solve the problem, either make sure that you start with an absolute path from the beginning, or, that your working directory is set correctly.
You can get/set the working directory using the Directory.GetCurrentDirectory and Directory.SetCurrentDirectory methods.
Your question is not very clear, but I think you're looking for this:
string path = Path.GetDirectoryName(filename);
If I have understood correctly, you have a filename, for example 'doc.txt', and you want to have a method to return the full path of this file regardless of where the application runs from?
If this is what you ask it is not possible. Have you considered that there might be several files called 'doc.txt' on your harddrives?
The best you can hope to do it to search all harddrives, and return a list of all files found with the same name, but that will just be ridicously slow.
