my basic idea is to launch the file in its default application, without me actually knowing it that is. so my program will actually will run anything after it launches its default application.
|
|
|
|
|
|
ShellExecute (NULL,"open","C:\\Program Files\\Winamp\\winamp.exe","D:\\Anshuman\\Songs\\abc.mp3",NULL,SW_NORMAL);
Somethings seem HARD to do, until we know how to do them.

in this case i can only launch mp3s... or sond files. but wat incase winamp is not insatlled. or the u want to launch .doc... then wat?
wat i see as a solution is to look in registry as to wat is the default applcation is for the type of file and then launch that application(that too after searching for its path in registry) with the file name as parameter.
is there a simpler method?

then in this case you would have to take the path of the exe in the string and the path of the file.
Pass it in the ShellExecute function based on the extension of the file

thats the whole point is... how to get the path of the application....

I think you do not need the path to executable. Just specify the path of your file, which can be MP3, JPG and so on:
ShellExecute( NULL, _T("open"), _T("c:\\myfile.mp3"), NULL, NULL, SW_SHOWNORMAL);
The system will open the default application associated with MP3 files.

definitely not.  (
simply "open" the .mp3 file, that's all you have to do to get the default application

ShellExecute (NULL,"open",NULL,"c:\song1.mp3",NULL,SW_NORMAL);
Did you suggest to do this as above.
// It didn't work. No winamp or media player showing instead the folder containing the project is opened.

not
ShellExecute (NULL, "open", NULL, "c:\song1.mp3", NULL, SW_NORMAL);
but
ShellExecute (NULL, "open", "c:\song1.mp3", NULL, NULL, SW_NORMAL);
do you get the difference ?

HKEY_CLASSES_ROOT\mp3file\shell\open\command
here you get the application associated with your MP3 File so simply search for other file types for launching the files.

The second parameter is the operation if it is NULL then
For systems prior to Microsoft® Windows® 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used.
For Windows 2000 and later systems, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry.

Perhaps if you indicated what the error was, we could be of more help.

Why would you expect it to if you got a compiler error?

for the second time, read this[^] post in a previous thread of yours...
notice that i don't directly open the exe but the file to be opened in its default application.

let me explain with an example:
BYTE* pbyte1 = new BYTE();
delete [] pbyte1;
The second line is suppsed to be just :
delete pbyte1;
So herez my question:
is there anything wrong with using the '[]' alongside teh delete operator even though the dynamically created variable is not of array type?
|
|
|
|
|
by using delete[] you are able to delete the memory occupied by the complete array.
in addition you can also assign a NULL to pByte1 . Clear to prevent using invalid memory reference.
Its the best way.

delete [] calls the constructer for each object of the array.
here you have created only one object of the BYTE.
so prefer second one.

When you use [] you are deleting the array.
and using the just delete pbyte you are deleting the pointer
and dont forget to set the pinter to NULL

IMHO, i better use Auto_ptr to deal with these problem!

thanx everybody for that quick reply!...
but the question i have asked still remains unanswered!
is there any problem(like mem leak, or unexpected error)when i use 'delete []' for an object that is not created as array?????
|
|
|
|
|
See my post for the thread.
delete x ; //works for a single object
delete[] x; // deletes the complete array
