IFileDocument.FindAll Method

Automation:

void FindAll ( [in] ref byte pDataToFind, [in] uint data_size, [in] IMultiSelection pSelection, [in] bool ignore_case, [in] IMultiSelection pFound) ;

Native (C++):

HRESULT FindAll ( [in] unsigned char * pDataToFind, [in] unsigned long data_size, [in] IMultiSelection * pSelection, [in] VARIANT_BOOL ignore_case, [in] IMultiSelection * pFound) ;

Parameters

pDataToFindPointer to a patterndata_sizePattern sizepSelectionMultiple Selection object, which contains ranges in which a pattern need to be locatedignore_caseTrue to ignore case, False to perform exact matching.pFoundMultiple Selection object, which contains, on method's return, all located ranges.

Return Value

S_OK or standard OLE error code.

Remarks

Locates all occurrences of a given pattern within a given multiple selection. You provide the function with an output Multiple Selection object pFound, in which it stores all located ranges. This object is automatically cleared before the operation begins. When the method returns, check the IMultiSelection.Empty property to see if there were any pattern occurrences. Complexity: linear-time, depending on the file's size and selection's complexity.

Examples

Searching all pattern occurrences

C#Copy Code

FileDocumentLib.FileDocument fdoc = new FileDocumentLib.FileDocument();
FileDocumentLib.IMultiSelection msel = fdoc.CreateEmptySelection();
FileDocumentLib.IMultiSelection mselOutput = fdoc.CreateEmptySelection();

fdoc.Open(@"c:\temp\file.txt");
msel.AddRange(0, fdoc.FileSize);  // We'll be searching in a whole file

byte[] pattern = new byte[] { 0x0d, 0x0a }; // EOL pattern
fdoc.FindAll(ref pattern[0], pattern.Length, msel, false, mselOutput);
if (!mselOutput.Empty) // check if there are any matches
  fdoc.Copy(mselOutput,false);  // copy them to the Clipboard
