One file is created. I want to set the file attribute as "READ ONLY" from VC++ coding. when file is in read only mode it can not write data. Right click on created file and uncheck the "Read Only" property of file, this file property change information ahould get notified in VC++ code.
After unchecking the file property, it is able to write data into created file.

How to set file permission/property in VC++? and how to get the notification of file property into VC++?

Hello,

Thanks for instant reply,
But still I am facing problrms while removing read only attribute from file properties, this file is not opened for writting data.
Using GetFileAttribute[^] is it possible to get the notification of file properties whether it is read only / write?

Can you show code ? you are using.
I'm sure this should work,

SetFileAttributes("filename",FILE_ATTRIBUTE_NORMAL);

See this[^] example for more info.

You need to mention this while opening file.

You can determine whether this file is readonly by using this API.

BTW, why you are mentining 'notifications" here ? Notification are different from what you had mentioned here.

This may be a naive answer, but you could use CreateFile() and set to read only access, then close the HANDLE to the file, and then reopen the file using CreateFile() and set the attributes to what ever you need them to be.

That might be a lot of opening and closing though.

Hi,
I am using following operations on file.
std::ofstream _logss;
const char * _filename = "xxx.out";
ofstream _logss(_filename,ios::out|ios::trunc);
file.open(_filename,ios::in);
Here I can not use CreateFile().

Please do needful.........

Hey,
Here is the code

const char * _filename = "xxxx.out";
std::ofstream _logss;
SetFileAttributes(_filename, FILE_ATTRIBUTE_READONLY);
if(GetFileAttributes(_filename) != FILE_ATTRIBUTE_READONLY)
{
.....
.....
if(_size >MAX_FILE_SIZE )
{
.....
ofstream _logss(_filename,ios::out|ios::trunc);
.....
}

I looked up MSDN and found the API function'SetConsoleWindowInfo ' ,which can resize,according to MSDN, the size and position of a console window, however,I tried it and found it doesn't work at all.I don't understand why the API doesn't work on my PC(IDE: VC++ 6.0 OS:WinXP SP2) Confused | :confused:

Some books says the API function,SetWindowPos,can changes Z order of a child, pop-up, or top-level window.I want to set the console window as the topmost window,so I use the API function ,but I don't know how to get the handle of a console window,I tried to get a console handle by the sentence, ConsoleHnd = GetStdHandle(STD_OUTPUT_HANDLE);
Unfortunately,I got the following error message:
error: argument of type "HANDLE" is incompatible with parameter of type "HWND".

Could anyone give me some suggestions? Thanks!

Use GetConsoleWindow.

use CreateProcess(..) function to launch a console, you can get handle of the console window there.

GetStdHandle(...) is related to handle of input/output buffer, which are not window's handle.

I believe you atleast need to specify one email address, to whom the email is to be sent.

I do think you are in SPAM.

remind:
email address is not helpful to hide yourself from punishment at all - fine for first SPAM is 4,000 and second is 1.1 million, this is australia price, I hope you will be fined much cheaper if you are in another country.
