Page.GetResults method (Visio)

Gets the results or formulas of many cells.

Syntax

expression. GetResults( _SID_SRCStream()_ , _Flags_ , _UnitsNamesOrCodes()_ , _resultArray()_ )

expression A variable that represents a Page object.

Parameters

Name	Required/Optional	Data type	Description
SID_SRCStream()	Required	Integer	Array identifying cells to be queried.
Flags	Required	Integer	Flags that influence the type of entries returned in results.
UnitsNamesOrCodes()	Required	Variant	Array of measurement units that results are to be returned in.
resultArray()	Required	Variant	Array that receives results or formulas of queried cells.

Return value

Nothing

Remarks

The GetResults method is like the Result property for the Cell object, except that it can be used to get the results (values) of many cells at once, rather than one cell at a time.

For a Page object, you can use the GetResults method to get results of any set of cells in any set of shapes of the page.

SID_SRCStream() is an array of 2-byte integers. For Page objects, SID_SRCStream() should be a one-dimensional array of 4 n 2-byte integers for n >= 1. The GetResults method interprets SID_SRCStream() as:

{sheetID, sectionIdx, rowIdx, cellIdx }n

where sheetID is the ID property of the Shape object on the page whose cell result is desired.

Note

If the sheetID in an entry is visInvalShapeID (-1) or if the bottom byte of sectionIdx is visSectionInval (255), the entry will be ignored and an empty variant will be returned in the corresponding results array entry. The reason for this is that the same SID_SRCStream() array can be used on several calls to GetResults, SetResults, and similar methods with the caller only needing to make minor changes to the stream between calls.

The Flags parameter indicates what data type the returned results should be expressed in. Its value should be one of the following.

Constant	Value	Description
visGetFloats	0	Results returned as doubles (VT_R8).
visGetTruncatedInts	1	Results returned as truncated long integers (VT_I4).
visGetRoundedInts	2	Results returned as rounded long integers (VT_I4).
visGetStrings	3	Results returned as strings (VT_BSTR).
visGetFormulas	4	Formulas returned as strings (VT_BSTR).
visGetFormulasU	5	Formulas returned in universal syntax (VT_BSTR).

The UnitsNamesOrCodes() parameter is an array that controls what measurement units individual results are returned in. Each entry in the array can be a string such as "inches", "inch", "in.", or "i". Strings may be used for all supported Visio units such as centimeters, meters, miles, and so on. You can also indicate desired units with integer constants (visCentimeters, visInches, and so on) declared by the Visio type library. Note that the values specified in the UnitsNamesOrCodes() array have no effect if Flags is visGetFormulas.

If UnitsNamesOrCodes() is not null, the application expects it to be a one-dimensional array of 1 <= uVariants. Each entry can be a string or integer code, or empty (nothing). If the i 'th entry is empty, the i 'th returned result is returned in the units designated by UnitsNamesOrCodes(j), where j is the index of the most recent prior non-empty entry. Thus if you want all returned values to be in the same units, you need only pass a UnitsNamesOrCodes() array with one entry. If there is no prior non-empty entry, or if no UnitsNameOrCodes() array is supplied, visNumber (0x20) is used. This causes internal units (like the ResultIU property of a Cell object) to be returned.

If the GetResults method succeeds, results returns a one-dimensional array of n variants indexed from zero (0) to n - 1. The type of the returned variants is a function of Flags. The resultArray() parameter is an out argument that is allocated by the GetResults method, which passes ownership back to the caller. The caller should eventually perform SafeArrayDestroy on the returned array. Note that SafeArrayDestroy has the side effect of clearing the variants referenced by the array's entries, hence deallocating any strings the GetResults method returns. (Microsoft Visual Basic and Microsoft Visual Basic for Applications take care of this for you.)

Example

The following example shows how to use the GetResults method. This example assumes there is an active page that has at least 3 shapes on it. It uses the GetResults method to get the width of shape 1, the height of shape 2, and the angle of shape 3.

This example uses the GetResults method of the Page object to get 3 cell formulas. The input array has 4 slots for each cell, as it also would for Master objects. For Shape or Style objects, only 3 slots would be needed for each cell (section, row, and cell).
