why not you use direct api for that.. as there is atleast one api for each internal command.. e.g. for ren - rename

Hi everyone,
Does anybody know what caused the 'bad file number' error? How to resolve that problem? And, is there a way to set the file number manually?
Thanks!
|
|
|
|
|
What 'file number error'? I don't know what you are talking about (maybe somebody does but not me  ). When does this error occur ? Be more explicit.

Hi, thanks for responding.
There was a problem with my program that it always return file pointer = NULL on the second (and further) attemps of openning file. So I tried to print out what error occured by using this command:
String error = strerror(errno) ;
The 'bad file number' was the message that I got in the string error.
Any idea?

Are you trying to open it when it hasn't been closed ? Maybe the problem is there.
|
|

I think I have closed it. Below is the function, probably you can find some errors there:
void afunct(AnsiString filename)
{
const char *file = filename.c_str();
FILE *fileptr = fopen(file, "rt");
if(fileptr == NULL)
{
perror("Unable to open file for reading");
String error = strerror(errno) ;
MessageBox(NULL,"Error",NULL,0);
exit(0);
}
else
{
//do something
}
fclose(fileptr);
}

Hi All,
I have customized File Open Dialog for my application (added a checkbox to it) and also overrode some of the default functionality.
I find that File Name Combo is not getting updated when the user selects a file from the list view.
Can anyone indicate where the problem could be?
Thanks and Regards,
Anil

Are you using Visual Studio 6 or .Net 2003

How we calculate the size of Jpeg image(not dimension),to recover the image if our system is formatted and the Original information about the size is Corrupted.

Whats the meaning of size?
|
|
|
|
|
Actually we want to find out the size of jpeg file in the compressed form.Because when we recover deleting JPEG file some time it is possible that the header cotaning information about size is cruptted then what we do in that case to calculate the size so we recover this jpeg file.

:|Hi all,
I want to know in an application the ID of the current mouse cursor at
any moment. I got the handle to the current cursor on server
machine and want to inform the client that cursor shape is changed
so that client can also reshape its mouse cursor.
Can i send the handle of the cursor on server to the client and
use that handle to reshape the cursor?
If not then how can i get the ID of the cursor from handle?
or any other way to do that.
Thanx

What the <blank> are you talking about. The mouse cursor belong to no application, unless it has captured it. It belongs to the system. Therefore it does not have or require an ID.
