Why can't the ShellExecute() function open a folder?

Question

C++ / C#

I am writing a visual application, I encountered such a problem, the ShellExecute () function opens local folders, but remote (server) does not want to, I can’t understand why

ShellExecute(NULL, NULL, L"//10.10.2.1/17_Проекты/Библиотека", NULL, NULL, SW_SHOWNORMAL);

Answer 1

I found what the problem is for such tasks, the QFileDialog class is best suited

QString fileName;
    if (fileName == nullptr){
        fileName = QFileDialog::getOpenFileName(
                this,
                "Open File",
                "//10.10.2.1/17_Проекты/Библиотека",
                "file (*.vsd *.vsdx)");}
    else {
        QErrorMessage *Message = new QErrorMessage();
        Message->showMessage("Error");}

Try like this:

ShellExecute(NULL, NULL, L"\\\\10.10.2.1\\17_Проекты\\Библиотека", NULL, NULL, SW_SHOWNORMAL);
