Syntax

procedure AssignFile(var F: File; const FileName: string); procedure AssignFile(var F: TextFile; const FileName: string);

Description

Call to assign a filename to a typed file, an untyped file, or a text file prior to opening the file. is not a active desktop recovery regedit script error procedure.

Tips and Tricks

  • A subsequent call to, or will open the file. If you do not call first, a call to, or causes Delphi to report I/O error 102.

  • Delphi interprets an empty string as the console. In a console application, the and files are automatically assigned to the console. Trying to use a console file in a GUI application results in I/O error 105.

Example

var LogFile: string = 'c:\log.txt'; // Append a message to a log file, delphi 7 einouterror. See the example with the Array // Keyword for the other overloaded Log procedure. procedure Log(const Msg: string); overload; var F: TextFile; begin AssignFile(F, LogFile); // Try to append to the file, which succeeds only if the file exists. {$IoChecks Off} Append(F); {$IoChecks On} if IOResult <> 0 then // The file does not exist, so create it. Rewrite(F); WriteLn(F, delphi 7 einouterror, Msg); CloseFile(F); end;

Hi, I惴 new to this group and to delphi.
It愀 a pleasure to be with you wise guys.

I惴 having problems with the following code.

var

f: TextFile;
begin
if OpenDialog1.Execute then
begin delphi 7 einouterror { open a text file }
AssignFile(f, OpenDialog1.FileName);
>> Append(f);
Writeln(f, 'I am appending some stuff to errors in verilog altera modelsim tutorial end of the file.');
{ insert code here that would require a Flush before closing the file }
delphi 7 einouterror Flush(f); { ensures that the text was actually written icq login error 10051 delphi 7 einouterror }
CloseFile(f);
end;

end;

It stops on the signed line (>>) and returns a exception :EInOutError with
the message 'I/O error 103

The file exists on the disk it snowgoons ft marph - terrorist lyrics created with

FileCreate(PathLoc + '\log.txt'); statement.

What愀 wrong?

Thanks in Advance

Augusto From Brazil

This is probably your problem. Try the following

var I : integer;
I := FileCreate(PathLoc + '\log.txt');
FileClose(I);

In addition to not having called FileClose, some other process may
have the file open exclusively.

Good luck.

You might be right, delphi 7 einouterror, Kurt, as to the actual problem, (file creation has left
it open or something else holds it open) - delphi 7 einouterror it needs assumptions that
there are typos in the post! - I'd expect 105 (access denied) then, not 103,
which is 'file not open' delphi 7 einouterror 103 should not occur on an append . (unless it
is a namespace problem and append does not do what we expect!) . though it
might occur on the writeln . (how could it reach that though, if the file
wasn't opened an exception should fire as there is no defence) ., delphi 7 einouterror. enough,
lets see if he comes back!

Yes, or I/O error 32. 103 (in my help system) says "File not open" -
but that should happen on the write, not the Append.

But this could be a file on the network which can give strange errors,
so.

Board index » delphi » EInOutError with message Invalid File Name


In your example, you will get an error if the directory
'C:\NewDirName\NewSubDir' already exists or if the intermediate directory
'C:\NewDirName' doesn't.

The compiler directive $I can tell this function to return an I/O result
instead of raising an exception. Rather than resort to this, why not check
out the ForceDirectories function? It can create an entire directory branch
and just returns True or False depending on whether it is successful or delphi 7 einouterror.

Example:
if  ForceDirectories('C:\NewDirName\NewSubDir') then
  MyString := 'Directory was created.'
else
  MyString := 'Nothing happened.'

Also, what relation does C:\NewAriel\Bin have to C:\NewDirName\NewSubDir?

System.SysUtils.EInOutError

EInOutError

Delphi

EInOutError=class(Exception)

C++

classPASCALIMPLEMENTATIONEInOutError:publicException

Properties

Description

EInOutError is the exception class for file input/output errors.

EInOutError is raised when a file input/output error occurs, provided I/O checking is enabled.

Note: In Delphi code, use the directive to enable I/O checking. If an I/O error occurs while this directive is disabled, the application must call IOResult to clear the error.

Note: In C++ programs, I/O checking is a project option.

The error code is available in the ErrorCode class member. Error codes come in ranges from 0 through 99 (native OS errors). An error number greater than 100 indicates a Delphi OS error.

Error codes in the range from 0 through 99 represent OS error conditions, delphi 7 einouterror. Refer to the OS documentation for complete error summaries. The SysErrorMessage function returns descriptive text for OS errors.

Here are some common OS I/O errors, delphi 7 einouterror.

Number

Name

Description

100

Disk read error

Reported by Read on a typed file if you attempt to read past the end of the file.

101

Disk write error

Reported by CloseFile, Write, WriteIn, or Flush if the disk becomes full.

102

File not assigned

Reported by Reset, Rewrite, Append, Rename, or Erase if the file variable has not been assigned a name through a call to Assign or AssignFile.

103

File not open

Reported by CloseFile, Read Write, Seek, Eof, FilePos, FileSize, Flush, BlockRead, or BlockWrite if the file is not open.

104 delphi 7 einouterror not open for input

Reported by Read, Readln, Eof, Eoln, SeekEof, delphi 7 einouterror, or SeekEoln on a text file if the file is not open for input.

105

File not citrix xen pool error for output

Reported by Write or Writeln on a text file if you do not generate a Console application.

106

Invalid numeric format

Reported by Read or Readln if a numeric value read from a text file does not conform to the proper numeric format.

Tip: When developing GUI applications and you need to provide delphi 7 einouterror I/O, delphi 7 einouterror, then you need to use the AllocConsole method in order to avoid a error. After you end your console I/O code block, call FreeConsole.

beginAllocConsole;Writeln('Console I/O is now enabled.');{ code block }FreeConsole;end;
{AllocConsole();printf("Console I/O is now enabled.\n");/* code block */FreeConsole();}

I get this error after installing Delphi XE, here is the full rm cannot remove input output error usb EPackageRegistrationException in module coreide150.bpl at
0006C339.
Registration procedure, Pasreg.IDERegister in package c:\program files
(x86)\embarcadero\rad studio\8.0\Bin\delphide150.bpl raised exception
class EInOutError: Mismatched borrower.
Do you want to attempt to load this IDE package the next time Delphi
XE is run?"

Delphi XE does not start up because of this error and I have tried
uninstalling and re-installing Delphi XE multiple times. I have also
made sure that update 1 is installed after installing Delphi XE and
still no luck. Anyone else having this issue?
