I'm very new to making visual programs and pretty new to C# to begin with.
I'm attempting to make a file browser that opens up files as well; I have several other questions but I'll just start with one.
I'm trying to populate a list of tabs/buttons across the top of the program with folders under a directory, and then when you click on one of the tabs it will change the tree view to show that directory (and sub-directories/files.)
I've got the file browser working- still working on opening files but I believe I got most of that done. I just need to figure out how to make these tabs.
EDIT: This is a windows application being created though VS Express.

I am writing a simple game for my course work. The application contains many pictureboxes with no images inside them. I also have a directory with needed pictures in the Visual Studio project debug folder. I need to put the pictures' paths into an array in my program to then randomly insert them into pictureboxes.
The problem is I don't know how it would work on another computer, so I can't organize all the things. The game must be launched without using Visual Studio there, only exe file. Should I first make the installation setup of my unfinished program, or something like this, and then place the application with resources somewhere on disk to know where all my pictures would be on any computer? And then maybe I could determine the exact path where I would take all the pictures and put them into the array. Or vice versa... I'm totally confused with this.
Here what I use to fill the array:
string[] spritePaths = Directory.GetFiles(/*paths*/);
Is it possible for you to distribute the pictures in a folder with the .exe file? If so, you could use a relative path to get all of the pictures.
string[] spritePaths = Directory.GetFiles("pictureFolder");
As DangerZone suggests, you could also add your images as embedded resources.
https://support.microsoft.com/en-us/help/319292/how-to-embed-and-access-resources-by-using-visual-c
Here are a few options:
Specify the path to the folder of images as a command line argument. Then you can launch it from CMD, or create a shortcut and specify the arguments there.
Add a TextBox for the user to enter the path to the images.
Add a browse button or menu button and allow the user to search for the folder using a dialog.
Use a predefined location, such as an images folder next to the exe.
For a project I have folders of images. An example folder might be ImagesOfDogs, and the images inside would be sequentially named (1.png, 2.png, etc.). I have a button, and when I press this button I want to open all of the images in a folder at once, in one window. I could make my own window, but I would rather use the default Windows program so the user can edit the photos. This would look like the following (just imagine that black thing is a really cute dog pic):
Let's say the path to a folder is a string titled sPathToFolderOfDogs. On my button click, I want a method like this:
private void OpenCoolPicsOfDogs()
{
Process.Start(sPathToFolderOfDogs);
}
Except that will open all enclosed files in an image viewing application, preferably whichever is the user default. I have tried:
Process.Start("PictureViewer", sPathToFolderOfDogs);
...which opens PictureViewer and does not open my photos in PictureViewer,
Process.Start(sPathToParticularImage1);
Process.Start(sPathToParticularImage2);
etc etc
...which opens each in a new window,
and possibly most creatively/desperately:
String[] arrayOfAllMyPathsToParticularImagesInTheFolder;
(put all the strings in the array)
Process.Start(arrayOfAllMyPathsToParticularImagesInTheFolder);
Which just crashed. I know opening folders in applications through Process.Start should be possible because it is done in the docs here.* Is there a way to do it with images?
*relevant code from link:
// Start Internet Explorer. Defaults to the home page.
Process.Start("IExplore.exe");
// Display the contents of the favorites folder in the browser.
Process.Start(myFavoritesPath);
Thanks!
It turns out my question was a duplicate. However, I am not deleting it, as the powers that be suggest it is best to keep duplicates up as a "signpost" informing future searchers where the true path lies.
Here is the answer to my question (or more specifically, about half a dozen equally functional answers to my question).
TL;DR: The solution I am now using is from #bruceatk in the above link.
I am building an add-in which requires selection of multiple outlook folders. For that purpose I created selection dialog that lists folders and allows user to select one or more by checking the check boxes next to tree view items.
I was hoping that somehow I could read/get the outlook folder icons from my add in code which is written in C# (any solution that works with outlook object model would do).
I was trying hard around MAPIFolder.GetCustomIcon but it returns null for all folders and when you read the documentation it is clear that it is not meant for this i.e. it returns value only if folder has custom icon and if it is not any of default folders.

Thanks for reading.
You'll have to use an icon editing tool (like Axialis Icon Workshop) that can extract icon and image resources from related Outlook .dll and .exe files. It's a real mess to figure out what icon is where there as they exist in small and large quantities in very many different files.
I have published my WPF application using ClickOnce publishing method. I ran the application on the client PC and I noticed that some of my images are not appearing e.g. Background images of Windows. I looked carefully and found out that one Sample.jpg Photo is properly showing inside the Image container which I've used for every record.
Same goes for another image n still coming. The problem I am not able to figure out why both these two images are coming and not the background one?
While creating the Application I have put all the images in a single Folder and all images are referenced from this single folder only.
I also tried by simply copying my project>BIN folder files to client machine and yes, all images are loaded properly without any issues. The problem is only coming in the publish version of my application.
Could anyone help me in this? are there any settings I should take care of while deploying the application? Or I should move them to any specific location?
Are your images Build Action property set to content and the Copy to Output directory property set to Copy always/Copy if newer?
How to open files from explorer into different tabs. I can associate an open with menu with the file type, now when I already have the program working, how to open the new file into another tab, instead of new program.
How to find the already running process exactly, not with the name and send the filename to it.
Let me make myself clear: I want my app to be single instance, so that when user select 10 text files and press enter key, my application will open all the 10 text files into 10 tabs, instead of creating 10 processes. How to do that? How to communicate between various instances of the same process.
EDIT SOLVED: Implemented the functionality using WM_COPYDATA in C# and the SingleApplication class from codeproject.
I am not quite sure what you mean in this question. Are you trying to open Windows Explorer windows into one window with tabs? If that is the case, then I recommend you look into QT TabBar, which extends Windows Explorer to allow for such behavior.
Or perhaps you are trying to have a link open to a new tab in a web browser. If that is the case, this behavior is defined by the web browser itself. For Internet Explorer 7, you can set this behavior under Tools > Internet Options.
In the General tab, click the Settings button next to the "Tabs" section. You will want to set the "Open links from other programs in:" option to open a new tab.
Keep in mind that this behavior is defined by each user, and you can't ever make any guarantees that they will have the same browser settings as you do.
After reading your comments, I think I understand a bit better. It sounds like you want your application to only allow one instance at a time. Since you tagged this post C#, I will assume that is what you are writing your program in.
Codeproject.com has a great tutorial on how to make your program only allow a single instance.
Here is a snippet of code from their site:
static void Main()
{
if(SingleInstance.SingleApplication.Run() == false)
{
return;
}
//Write your program logic here
}
You would want to write code just before the return statement to have the existing instance open the file in a new tab.
If you are able to provide detailed information about what your program is doing, we might be able to help you with some of the specifics.
