Check to see if it has a .lnk extension.

Difference between delete and delete[]

16-Feb-04 4:43

What constitutes a shortcut on a Unix box (they used to be called nodes) is different than what constitutes a shortcut on a Windows box. There is no way for a Windows box to "ask" a Unix box if such-and-such file is a shortcut or not.

That's true. Unless you can execute something like a stat() on the file at the UNIX end, you have no way of determining that it is anything other than a regular file. You can't even tell if it's a file with multiple hard links, much less something more esoteric, like a soft link or a device file.

Hello !
Juste a little question.

What is exactly the difference between delete and delete[] ?
Is the second used to delete memory allocated for more than one element and the first when only one element was allocated ?

Thanks

delete[] assumes that the block of memory pointed at is an array of (the same kind of) objects where the delete operator needs to call the destructor for each element in the array.

Both c++ commands are used to deallocate memory that was previously created. However, delete [] instructs the compiler that the given memory location is an array of allocated space (usually created using the new [] keyword).

The general rule is to use

delete with new

and

delete [] with new []

Re: Creating shortcuts in Start menu

15-Feb-04 22:54

Hi, I'd like to be able to create a shortcut in the start menu like office does. Instead of putting it in the Programs > section, it puts it in the main Start Menu window?

How can I do this? Thank you,

Programmatically copying a folder in MFC

Ashman15-Feb-04 22:53

15-Feb-04 22:53

Hi, I need to know how to copy a folder and all the contents within to another location set by the user. Because the folders content is read only, I want to be able to make ReadOnly(FALSE);

Is this possible, please help!

Thanks in advance

SHFileOperation will help out, its very good api to work around with files and folder.

Thanks
I searched for SHFileOperation() API calls and I don't understand how to implement it in my program.

Do you have/know of an example that I can use. What I want to do is very basic; transfer 2 folders with all their files intact from location:

D:\Programming\NeriedPOS\nbsSetup\nPOS & D:\Programming\NeriedPOS\nbsSetup\nManager

to C:\Program Files\nPOS with ReadOnly(FALSE)

Would you kindly be able to show me how to do that using SHFileOperation() or any other API?

Please help...its kinda urgent considering I have almost run out of hair to pull Smile | :)

Thanks
Ashman

David Crow16-Feb-04 2:36

This

SHFILEOPSTRUCT shfo = {0};
shfo.wFunc = FO_COPY;
shfo.pFrom = "D:\\Programming\\NeriedPOS\\nbsSetup\\nPOS\\*.*\0";
shfo.pTo   = "C:\\Program Files\\nPOS\0";
SHFileOperation(&shfo);

should get you started.

Hello ,

Is there any SDK to implement the AUto-Upgrade feature .I am writing a application in vc++ .Is there anything ,that i can use some SDKs that can be used to check for upgrades for my application from a URL /server ?

How do you get the functions exported by the dll and

16-Feb-04 2:36

What I did, which was kind of slow maybe to create an autoupdater was to get my program to connect to the server, navigate to updates folder and open a file which was similar to an ini file. Get the current version of the program the user is running, set a variable for each new version like; Version 1.10a = 1 and Version 1.10b = 2 etc.

On the server say the new version is Version 1.10c which = 3, try like: Note this is using CIniEx as an example...

<br />
CString strVersion;<br />
ini.Open("Version.ini");<br />
strVersion=ini.GetValue("Program","Version");<br />
<br />
if(strVersion == "3") //Just an example, or just get the string value from a file on the webserver<br />
{<br />
//You have the current version<br />
}<br />
else {<br />
//Open another file to get the location of the new updated program and then download it and execute it<br />
}<br />
<br />

Just a suggestion....bit hard to explain considering Im a complete knob. For some reason things just work themselves out for me programmatically Confused | :confused:

. Hope that helped. Unsure | :~

Please refer this .....Basically u need to inform the compiler using some macros that these functions need to be exported
