open file window (open...)

I have been looking for the answer but I couldn't find what I am looking for...
I want, using API, open that window where it is possible to select a file. Almost all program has this option inside menu "file" >> "open..."

I would like to know if there is any specific function to do that !! ?

or any tutorial where I could get info about it.

If someone knows the answer for that help me!

Thanks

CFileDialog Tutorial Step by Step

This tutorial seems to be used with MFC...I would like to know what would give me the same result but with API.

Thanks

GetOpenFileName

Code:

---

char        szExtBuffer[MAX_PATH] = "";
OPENFILENAME ofn;

strcpy(szExtBuffer, "*.txt; *.log");

ofn.lStructSize      = sizeof(ofn);
ofn.hwndOwner        = 0;
ofn.hInstance        = 0;
ofn.lpstrFilter      = 0;
ofn.lpstrCustomFilter = 0;
ofn.nMaxCustFilter    = 0;
ofn.nFilterIndex      = 0;
ofn.lpstrFile        = szExtBuffer;
ofn.nMaxFile          = MAX_PATH;
ofn.lpstrFileTitle    = 0;
ofn.nMaxFileTitle    = 0;
ofn.lpstrInitialDir  = 0;
ofn.lpstrTitle        = "Open file";
ofn.Flags            = 0;
ofn.nFileOffset      = 0;
ofn.nFileExtension    = 0;
ofn.lpstrDefExt      = 0;
ofn.lCustData        = 0;
ofn.lpfnHook          = 0;
ofn.lpTemplateName    = 0;

// Open dialog
if(::GetOpenFileName(&ofn) == FALSE)
  // Cancel pressed

Code:

---

ofn.lStructSize      = sizeof(ofn);
ofn.hwndOwner        = 0;
ofn.hInstance        = 0;
ofn.lpstrFilter      = 0;
ofn.lpstrCustomFilter = 0;
ofn.nMaxCustFilter    = 0;
ofn.nFilterIndex      = 0;
ofn.lpstrFile        = szExtBuffer;
ofn.nMaxFile          = MAX_PATH;
ofn.lpstrFileTitle    = 0;
ofn.nMaxFileTitle    = 0;
ofn.lpstrInitialDir  = 0;
ofn.lpstrTitle        = "Open file";
ofn.Flags            = 0;
ofn.nFileOffset      = 0;
ofn.nFileExtension    = 0;
ofn.lpstrDefExt      = 0;
ofn.lCustData        = 0;
ofn.lpfnHook          = 0;
ofn.lpTemplateName    = 0;

This is too much code in my eyes, since it would go easier:

Code:

---

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize      = sizeof(ofn);
ofn.lpstrFile        = szExtBuffer;
ofn.nMaxFile          = MAX_PATH;
ofn.lpstrTitle        = "Open file";

---

Or even better:

Code:

---

OPENFILENAME ofn = { 0 };

ofn.lStructSize      = sizeof(ofn);
ofn.lpstrFile        = szExtBuffer;
ofn.nMaxFile          = MAX_PATH;
ofn.lpstrTitle        = "Open file";

This discussion was very usefull
Thank you all,

This kind of depends on the actual parameters you want to set though... :cool:

Of course. Since 80% of your code are zero setters, so you can make it smaller with my suggestion.
