Overload List
| # | Signature | Description |
|---|---|---|
| 1 | Int32 ValuesToStrings(TStrings dstList, Int32 ListIndex, Int32 Row, Int32 Col, Int32 RowCount, Int32 ColCount, String Delimiter, TFixedTextAlign Align, Boolean Headers, Int32 ColumnWidth) | Convert calling matrix elements, starting with [Row,Col] and up to [Row+RowCount-1,Col+ColCount-1] elements to strings. |
| 2 | Int32 ValuesToStrings(TStrings dstList, String Delimiter, TFixedTextAlign Align) | Converts the content of the matrix Values array to a list of strings. |
| 3 | Int32 ValuesToStrings(TStrings dstList, String Delimiter, TFixedTextAlign Align, Boolean Headers, Int32 ColumnWidth) | Converts the content of the matrix Values array to a list of strings. |
Overload 1: Int32 ValuesToStrings(TStrings dstList, Int32 ListIndex, Int32 Row, Int32 Col, Int32 RowCount, Int32 ColCount, String Delimiter, TFixedTextAlign Align, Boolean Headers, Int32 ColumnWidth)
Convert calling matrix elements, starting with [Row,Col] and up to [Row+RowCount-1,Col+ColCount-1] elements to strings.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | dstList | TStrings | |
| 2 | ListIndex | Int32 | |
| 3 | Row | Int32 | |
| 4 | Col | Int32 | |
| 5 | RowCount | Int32 | |
| 6 | ColCount | Int32 | |
| 7 | Delimiter | String | |
| 8 | Align | TFixedTextAlign | |
| 9 | Headers | Boolean | |
| 10 | ColumnWidth | Int32 |
Returns: Int32
Use text Delimiter for columns and store the resulting strings in dstList starting at ListIndex. If dstList is not large enough, the method will use the Add method of dstList object. Existing items will be overwritten. Set Align to have columns aligned left or right when using fixed width font (like Courier New). Specifiy Headers to be "true", if row and column labels are to be printed.
Performance note:
This routine will be exceedingly slow, if TRichEdit.Lines or TMemo.Lines are passed as a parameter. Use TStringList or StringList types and then call Memo.Lines.AddStrings(yourList) for best results.
Overload 2: Int32 ValuesToStrings(TStrings dstList, String Delimiter, TFixedTextAlign Align)
Converts the content of the matrix Values array to a list of strings.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | dstList | TStrings | |
| 2 | Delimiter | String | |
| 3 | Align | TFixedTextAlign |
Returns: Int32
Performance note:
This routine will be exceedingly slow, if TRichEdit.Lines or TMemo.Lines are passed as a parameter. Use TStringList or StringList types and then call Memo.Lines.AddStrings(yourList) for best results.
Overload 3: Int32 ValuesToStrings(TStrings dstList, String Delimiter, TFixedTextAlign Align, Boolean Headers, Int32 ColumnWidth)
Converts the content of the matrix Values array to a list of strings.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | dstList | TStrings | |
| 2 | Delimiter | String | |
| 3 | Align | TFixedTextAlign | |
| 4 | Headers | Boolean | |
| 5 | ColumnWidth | Int32 |
Returns: Int32
Convert all elements of the calling matrix to strings with text delimiter Delimiter and store them in dstList, by using the Add method of TStrings object. Set Align to have columns aligned left or right when using fixed width font (like Courier New). Specifiy Headers to be "true", if row and column labels are to be printed.
Performance note:
This routine will be exceedingly slow, if TRichEdit.Lines or TMemo.Lines are passed as a parameter. Use TStringList or StringList types and then call Memo.Lines.AddStrings(yourList) for best results.
