Parameters

The following parameters are available:

Parameter	Description

lpCellType	Pointer to structure to contain cell type information
Style	Number style Use the (\|) OR operator and combine the following values as indicated:
	Constant	Description
	SSS_ELLIPSES	Displays an ellipsis (...) when text is too long to fit in the cell
	SSS_NEGRED	Shows the text in red for a negative number
	Use one of the following values:

	SSS_ALIGN_BOTTOM	Aligns text at the bottom of cells
	SSS_ALIGN_VCENTER	Centers text vertically within the cell
	Use one of the following values:
	SSS_ALIGN_LEFT	(Default) Aligns text to the left in the cell
	SSS_ALIGN_RIGHT	Aligns text to the right in the cell
	SSS_ALIGN_CENTER	Centers text horizontally within the cell
	Use one of the following values:
	SSS_TEXTORIENT_VERT_LTR	Displays text vertically in the cell and wraps from left to right
	SSS_TEXTORIENT_DOWN	Rotates text 90 degrees (to "3 o'clock")
	SSS_TEXTORIENT_UP	Rotates text 270 degrees (to "9 o'clock")
	SSS_TEXTORIENT_INVERT	Rotates text 180 degrees (to "6 o'clock")
	SSS_TEXTORIENT_VERT_RTL	Displays text vertically in the cell and wraps from right to left
Right	Number of digits to right of decimal place
Min	Minimum valid number value The smallest value allowed is –1.7E+308.
Max	Maximum valid number value The largest value allowed is 1.7E+308
lpszDecimal	Decimal character

Remarks

This function is applied to the current sheet setting unless you first call the SSSetSheet function to specify the sheet for which you are calling this function.

This function sets a scientific cell type that lets you customize the number format.

This function initializes a structure of the specified type (SS_CELLTYPE). You can use this structure to set an individual cell or block of cells using the SSSetCellType or SSSetCellTypeRange functions.

The control uses the regional Number Decimal Symbol and Digital Grouping settings in the Windows Control Panel. If you want to specify different decimal or separator characters, use the lpszDecimal and lpszSeparator parameters.

Notes:

Do not use a plus sign ("+"), a minus sign ("–"), or a space as a decimal character.
The control does not recognize changes made to the regional Windows settings until you restart your development environment or your application (or perform any operation that unloads and reloads the current control files). For more information about regional settings and Windows operating environments, see Variations in Windows Regional Settings or Options.

The value specified for the Max parameter is the maximum value the control allows the user to type or paste into the cell. If the user tries to type or paste a value greater than the value specified, the control beeps (unless you have called the SSSetBool function and set the SSB_NOBEEP boolean to TRUE) and the user is not allowed to type the value.

Values larger than the specified maximum value can still be added to the cell in code at run time; when they are added in code, the value is allowed in the cell. However, the control adjusts those values to be zero the next time the cell is in edit mode. If the cell leaves edit mode with no change to the value, though, the control changes the value back to the invalid value.

The value specified for the Min parameter is the minimum valid value for the cell. When the user types or pastes a value smaller than the minimum value into the cell, the control sends the SSN_INVALIDDATA message when the cell leaves edit mode, but the user's value is allowed in the cell. Values smaller than the specified minimum value can also be added to the cell in code at run time; when they are added in code, the value is allowed in the cell and the control does not send the SSN_INVALIDDATA message.

Return Value

Pointer to the SS_CELLTYPE structure, or NULL if any of the parameters are invalid.
