GetFiles

I am using Directory::GetFiles Method (Path, SeachPattern) to find .txt files in folders. The code that I am using look like this (I will put the selected folders *.txt files in the textBox1):

Code:

folderBrowserDialog1->ShowDialog();
System::String ^ files3 = folderBrowserDialog1->SelectedPath; 

this->textBox1->Text = Directory::GetFiles(files3,"*.txt");

The compiler says that "Directory" is a undeclard identifier and left of .GetFiles must have class/struct/union.

I am not sure if I can figure out what is missing, I have a feeling that I need a string array in any way ?

Directory is located inside System::IO. So either use
System::IO::Directory::GetFiles or put using System::IO;
in your source file, I believe.

Yes I tried this too but was not sure if it was needed but I have put this now then and the compiler says:

cannot convert parameter 1 from 'cli::array<Type,dimension> ^' to 'System::String ^
with
[
Type=System::String ^,
dimension=1
]

I am not sure what could be ment by this. What is a cli::array etc...
It seems that files3 get another format when using System::IO as that perheps is using this format and then it needs to be converted
to System::string ^ that a text1 box can use.
I will look this up.

It's obvious to me that it's an array, just upon reading the word cli::array.

I cant figure this out. I have googling all examples of this but cant find anything that I can understand.

I dont really understand the first logic of what is needed to do. All that an array should be needed in any way and this array is called: cli::array. What is the difference with a cli::array and an array.
Following a msdn example and trying to do something, I have done this:

Code:

	folderBrowserDialog1->ShowDialog();
	System::String ^ files3 = folderBrowserDialog1->SelectedPath; 
		
	List<String ^> ^files4 = gcnew List<String ^>;
                List = System::IO::Directory::GetFiles(files3,"*.txt");
		
	this->textBox1->Text = List;

So the only thing I can think of what I am doing is to create a List Array of String ^ type where I will put all .txt files in. So later when write List = System::IO etc... files3 will be saved in this List with correct file type, string ^ so this later will be put in the textBox1.
So any point in the right direction would be needed I think.

My understanding is that an array in C++/CLI is of type cli::array. So cli::array is an array, and there's no such thing as "pure" array as in just a collection of objects. You can see it as similar to std::vector as an array.

okay. That makes it a bit easier to understand that. I dont know if it is ment to write something like this then. Still when doing this std::vector * cannot convert to System::string ^:
Anyway I suppose I will fill up what ever will be where List = is now with all the files found in files3. If I can understand that it would be easier to continue solving the function needed.
Thanks...

Code:

std::vector<string> List(100);

List = System::IO::Directory::GetFiles(files3,"*.txt");

I never said use std::vector. Managed and native don't mix.
I suggest you go back to C# or just unmanged C++, because this obviously seem to confuse you to no end.
Do not mix native and managed.
Mmkay? Your code above will fail in very possible kind of way.
And again, I don't know C++/CLI, so I don't know how arrays work there, and I don't know how to solve your problem.

okay that is no problem, I understand. For the moment I have no time to change to C# because it will meen for me to translate 15 pages with code and solutions and that will take another month or more because I am quite new to this. Anyway I have that in mind for later to mention. Perheps if can come nearer a solution I can post again and see if someone have any idea.
thanks..
