hey guys, i have a problem with using mci, i have code to display the file open dialog which displays only mp3 and wma files, after selelcting a file the file extension is stored in szFileName: if(GetOpenFileName(&ofn)) { MessageBox(hwnd,szFileName,"File OPen",0); mciSendString("",szFileName,128,hwnd); } OK, Now, if i compile this i get no errors and no warning, when i choose to run, i get "The procedure entry point SMapLS could not be located in the dynamic link library KERNEL32.dll." When i comment out the mcisendstring() and leave the messagebox(), it runs fine and returns the correct full path of the file. What am i doing wrong with the mcisendstring function. Also note, i linked the winmm.dll and am using mmsystem.h I cant figure out what i'm doing wrong.

First you need to open the file:

string Command;
Command="open "+szFileName;
mciSendString(Command.c_str(),NULL,0,hwnd);

Then play it:

Command="play "+szFileName+" from 0";
mciSendString(Command.c_str(),NULL,0,hwnd);

I was wondering, if there was a way to use char instead of string command.

This doesnt work for me, i created a new var of type string called Command, and pasted your code, but i get errors with +szFileName+ and how (+)'s are binary operatives, i include string.h

ok, i finally have the program compiling after adding your codem however i get the same error, about the entry point, here is a snip of my code.
_--------------------------------------------------

case IDM_OPEN:
{
OPENFILENAME ofn;
char szFileName[MAX_PATH] = "";

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(ofn); // SEE NOTE BELOW
ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "MPlayer Files(*.wma,*.mp3)\0*.mp3\0All Files (*.*)\0*.*\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "wma","mp3";
if(GetOpenFileName(&ofn))
{
sFileName=szFileName;

string FileName;
FileName="open "+sFileName;
mciSendString(FileName.c_str(),NULL,128,hwnd); <--/*The error lies here, i can replace mciSendString with MessegeBox(hwnd,FileName.c_str(),"open",0 ) and it displays the full extension with the word open in front of it.*/

}
}
break;
