Nope. I am searching for one. Even the one you said hasn't got a tooltip.

How are you trying to catch the exception?
If you can catch the exception using a catch all (catch(...)), then you are likely not catching the MFC exception correctly.
Remember that MFC exceptions are caught by pointer, not by reference or value. And you must call Delete() off of the caught exception pointer if you do not re-throw it.

# pragma directive is one of best way to include the lib file.. but you can also add to you rpoject by just adding libaray file same way you add .cpp and .h file

I want to execute an internal command in my program.
e.g. ren a.txt b.txt
winexec and ShellExecute do not execute internal commands.
system() executes it;
system("ren a.txt b.txt");
it wors fine; but shows consol window which i donot want to show.
Is there a way to execute the internal command without showing the consol window?
Thanks in advance ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

In addition to the above responses, you could also try: (I know WinExec is old but since it works still)
WinExec("cmd /c ren c:\\a.txt b.txt", SW_HIDE);
It is the /C switch which causes cmd.exe to terminate after executing the command. And the second parameter to WinExec: SW_HIDE causes the window not to be shown.
If the program should run on Win9X also, then make it command.com instead of cmd.exe.
this is this.

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
