You just call GetOpenFileName or GetSaveFileName.

here it is in my minigui.d

Very complicated. Can you send me the simple clear code?

Have a look at this website: http://www.winprog.org/tutorial/app_two.html
It helped me a lot when i once made a simple gui in C.
The tutorial is in C, but Win32 Api is C anyway... Most of the examples will probably just compile in D.
Win32 Api is really ugly, i think it's a better investment to learn something like GtkD ;)

Not compile in Dlang.

Tha examples in this site don't compile in Dlang. I want Win32 Api becouse I want create very smal window gui for simple programs.

This code works, but I can't get file Path. Someone can help me?

import std;
import core.sys.windows.windows;
pragma(lib, "comdlg32");

void main(){
    OPENFILENAME ofn;
    wchar* szFileName;
    (cast(byte*)& ofn)[0 .. ofn.sizeof] = 0;
    ofn.lStructSize = ofn.sizeof;
    ofn.hwndOwner = null;
    ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
    ofn.lpstrFile = szFileName;
    ofn.nMaxFile = MAX_PATH;
    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
    ofn.lpstrDefExt = "txt";
    if(GetOpenFileNameW(&ofn)){
      writeln(szFileName); // Print null
      writeln(ofn.lpstrFile); // Print null
    }
}

You need to supply a buffer, not a pointer:

  wchar[MAX_PATH] szFileName;

The above lines are unnecessary as D structs are automatically initialized and lStructSize is already filled in.

It wants a pointer to your buffer:

  ofn.lpstrFile = szFileName.ptr;

You'll need to slice the buffer to the right length:

  import core.stdc.wchar_ : wcslen;
  writeln(ofn.lpstrFile[0 .. wcslen(ofn.lpstrFile.ptr)]);

Solution:

import std;
import core.sys.windows.windows;
pragma(lib, "comdlg32");

// Function askopenfilename()
string askopenfilename(const(wchar)* filter = ""){
    OPENFILENAME ofn;
    wchar[1024] szFileName = 0;
    ofn.lpstrFile = cast(LPWSTR) szFileName;
    ofn.lpstrFilter = filter;
    ofn.nMaxFile = MAX_PATH;
    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
    if (GetOpenFileNameW(&ofn)){
        return to!string(szFileName[0..szFileName.indexOf('\0')]);
    } else {
        return "";
    }
}

void main(){
    writeln(askopenfilename()); // Call without filter.
    writeln(askopenfilename("Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0")); // Cal using filter.
}
