TdxCustomMemData.SaveToTextFile(string) Method
Saves stored data to a plain text file.
Declaration
procedure SaveToTextFile(const AFileName: string); dynamic;
Parameters
Name | Type | Description |
---|---|---|
AFileName | string | The path to the target plain text file. |
Remarks
Call the SaveToTextFile
procedure to save stored data to a plain text file. You can call the LoadFromTextFile procedure to load data from the created file later.
To define a character used as a column separator, use the DelimiterChar property.
Important
SaveToTextFile
and LoadFromTextFile procedures depend on the current locale settings. The LoadFromTextFile procedure may not be able to load a text file created on a machine with different locale settings.
To ensure that saved data is loaded correctly regardless of locale settings, use SaveToBinaryFile, SaveToStream, LoadFromBinaryFile, and LoadFromStream procedures instead.
Code Example: Copy Data Between Datasets as Plain Text
The following code example sets a semicolon as a column separator and copies data between two memory-based datasets through a plain text file.
dxMemData1.DelimiterChar := ';'; // Sets a semicolon as a column separator
dxMemData1.SaveToTextFile(ExtractFileDir(Application.ExeName) + 'data.txt');
dxMemData2.DisableControls; // Disables data synchronization with bound controls
try
dxMemData2.DelimiterChar := ';'; // Sets a semicolon as a column separator
dxMemData2.LoadFromTextFile(ExtractFileDir(Application.ExeName) + 'data.txt');
finally
dxMemData2.EnableControls; // Re-enables data synchronization with bound controls
end;
