Thread: FindFirstFile

The 1:st Code, I have put inside a buttoncontrol. This does open a folderBrowserDialog. When I select a folder and press OK. The SelectedPatch is inserted in a textBox1.
What I am trying to do here now is with the 2:nd code to choose a folder and when pressing OK here I want all files that is ".txt" to be inserted into this textBox1.
I know I will have to use FindFirstFile, FindNextFile and FindClose in a way.
I have tried out the first thing to Catch The first .txt file but this doesn´t compile.
Any ideas what it could depend on.



1:st

Code:

folderBrowserDialog1.ShowDialog();
this.textBox1.Text = folderBrowserDialog1.SelectedPath;

2:nd

Code:

Handle h;
LPWIN32_FIND_DATA lpFileName;
h = FindFirstFile(folderBrowserDialog1.SelectedPath, &lpFileName);
			
this.textBox1.Text = h;

Okay I really dont know the exact meening with Native APIs.

Should I use the technique with FindFirstFile etc.. ?

If you are doing C# .NET, please please don't touch those Native APIs!

hm, not sure of your problem but here is a function I wrote quick, hopefully it helps :

Code:

        /*########################################*/
        /*########################################*/
        /*########################################*/
        public bool _Folder_GetFiles(string vSourceDirectory, out string[] vFileNames)
        {
            try
            {
                int vRecursionDepth = 4;
                int vHowDeepToScan = 4;
                if (vRecursionDepth <= vHowDeepToScan)
                {
                    string[] fileEntries = Directory.GetFiles(vSourceDirectory);
                    vFileNames = fileEntries;
                    return true;
                }
                else
                {
                    vFileNames = null;
                    return false;
                }
            }
            catch
            {
                vFileNames = null;
                return false;
            }
        }
        /*########################################*/
        /*########################################*/
        /*########################################*/

ps. It's a short version of a recursive one I use which gets ALL files in ALL subfolders so that's why the code is a bit "weird" looking.

Thanks a lot I will check this code out and see what I can do.

                return false;
            }
        }

Your if else will always be true anyway.

Yes, well as I stated, my function is just a small cut off from a larger function. I pasted it quickly just to give him a hint so I had to cut off a lot of code from the function which you see there.
