What is your actual connection string? The error indicates otherwise. Also is your database or its alias really called ttt , or did you anonymize the error message as well?

The error could also indicate that the database server does not have write access to the specified location. If this flag is not specified, but the file or device has been opened for delete access, the function fails. If this flag is not specified, but the file or device has been opened for read access, the function fails.

If this flag is not specified, but the file or device has been opened for write access or has a file mapping with write access, the function fails. If this parameter is NULL , the handle returned by CreateFile cannot be inherited by any child processes the application may create and the file or device associated with the returned handle gets a default security descriptor.

If this member is NULL , the file or device associated with the returned handle is assigned a default security descriptor. CreateFile ignores the lpSecurityDescriptor member when opening an existing file or device, but continues to use the bInheritHandle member. The bInheritHandle member of the structure specifies whether the returned handle can be inherited. If the specified file does not exist and is a valid path, a new file is created, the function succeeds, and the last-error code is set to zero.

If the specified file does not exist and is a valid path to a writable location, a new file is created. If the specified file does not exist and is a valid path to a writable location, the function creates a file and the last-error code is set to zero. Additional SQOS-related flags information is presented in the table following the attributes and flags tables. For more advanced access to file attributes, see SetFileAttributes. For a complete list of all file attributes with their values and descriptions, see File Attribute Constants.

For more information, see the Caching Behavior section of this topic. You must set this flag to obtain a handle to a directory. A directory handle can be passed to some functions instead of a file handle. For additional information, see the Caching Behavior section of this topic. For more information, see Impersonation Levels. This allows the client to limit the groups and privileges that a server can use while impersonating the client.

The template file supplies file attributes and extended attributes for the file that is being created. When opening a new encrypted file, the file inherits the discretionary access control list from its parent directory. For additional information, see File Encryption. If the function succeeds, the return value is an open handle to the specified file, device, named pipe, or mail slot.

To get extended error information, call GetLastError. The text attempts to use the word file only when referring specifically to data stored in an actual file on a file system. This liberal use of the term file is particularly prevalent in constant names and parameter names because of the previously mentioned historical reasons.

When an application is finished using the object handle returned by CreateFile , use the CloseHandle function to close the handle. This not only frees up system resources, but can have wider influence on things like sharing the file or device and committing data to disk. Specifics are noted within this topic as appropriate. To avoid the sharing violation in this scenario, open the remote file or directory with the DELETE access right only, or call DeleteFile without first opening the file or directory for deletion.

Some file systems, such as the NTFS file system, support compression or encryption for individual files and directories. On volumes that have a mounted file system with this support, a new file inherits the compression and encryption attributes of its directory. You cannot use CreateFile to control compression, decompression, or decryption on a file or directory. Windows Server and Windows XP: For backward compatibility purposes, CreateFile does not apply inheritance rules when you specify a security descriptor in lpSecurityAttributes.

To support inheritance, functions that later query the security descriptor of this file may heuristically determine and report that inheritance is in effect. As stated previously, if the lpSecurityAttributes parameter is NULL , the handle returned by CreateFile cannot be inherited by any child processes your application may create.

The following information regarding this parameter also applies:. Note that CreateFile with supersede disposition will fail if performed on a file where there is already an open alternate data stream. Some of these flags should not be combined. Performance gains can be even more noticeable for applications that read large files mostly sequentially, but occasionally skip forward over small ranges of bytes. If an application moves the file pointer for random access, optimum caching performance most likely will not occur.

However, correct operation is still guaranteed. The operating system also requests a write-through of the hard disk's local hardware cache to persistent media. Using these flags together avoids those penalties.

For general information about the caching of files and metadata, see File Caching. I use direct path, becasue this is test project. DatabaseName: Maybe you can create a very small test-project which reproduces this problem so we can test this.

I try to open to another. If I use ZConnection and set this gbd databasename it works fine. This gdb file is working perfectly with ZConnection. I uninstalled lazarus ibx, firebird, IBExpert, etc but unfortunately not working.. I do not understand. GetMem Hero Member Posts: It works fine for me IBX 2.
