      I’m not sure about your definition of “sometimes this function fails and returns -1”
      because -1 is the return value if the text to be searched for is not found.
      But if you are sure that the text should have been found I assume
      you are using a thread, could that be?

        @Ekopalypse, I meant that the function fails to find the text I am looking for, so it returns -1. Also, what do you mean by thread?

          what do you mean by thread?

          Do you create a thread within your plugin which is doing the search?
          If so, this is not safe as npp itself does a lot of SETTARGETRANGE,
          which means that your plugin code SCI_SEARCHINTARGET could
          be searching on unknown territory.

            Do you mean like this?help2.png

            My main plugin function is “Parse and Format Log File”, and I use “Test123” to help me test some of the code I’m writing and, “FindIt” is the function that I posted above.

            Sorry, I’m really new at this, so I don’t know what you mean completely.

              No, I mean this.
              So because you don’t know about threads we assume you
              are not using it. Then I would assume that the text to be
              searched is not in the main scintilla but in the second, could this be?

                I don’t know the difference between main and second scintilla. Could you tell me?

                  Open a clean npp without any files.
                  Create a new tab so that you have new_1 and new_2
                  Now right click on the tab and do move to other view for one of the tabs.
                  Result: one buffer can be accessed by nppData._scintillaMainHandle and the other by nppData._scintillaSecondHandle.

                    I see what you mean, so a tab is only second scintilla if it’s in the other view? I have only tried my plugin on tabs that are in the regular view, so I would assume all my text is in the main scintilla. Thanks for explaining that, but I don’t think that’s the problem

                      only second scintilla

                      Not strictly true, if you have two views open and you close the
                      main view the second view stays to be the second.

                      The only other suggestion I can make is that you try to find a
                      pattern when it returns -1 where it should return something else.

                        This is what I have been trying to do. Usually, I have to wait a bit for it to work, or when I reopen notepad it starts to work again, or when I go to a different piece of text and then come back to it, it works. The lack of consistency has made it hard to try and figure this out. Thanks for the help anyways, I appreciate it

                          We don’t talk about casing problem,
                          I mean you are searching for “xml version” and expect to find
                          “XML version”, do we?

                            I tell it to search for, “xml version”, but specifically it should find, help3.JPG
                            in a text file that looks a bit like this
                            help4.JPG

                              maybe you should, explicitly, set your searchFlags.

                                That could be it, but why would it be only working sometimes?

                                  only second scintilla

                                  Not strictly true, if you have two views open and you close the
                                  main view the second view stays to be the second.

                                  I second @Ekopalypse. In my plugins, I use:

                                  HWND getCurScintilla()
                                  {
                                      int which = -1;
                                      ::SendMessage( nppData._nppHandle, NPPM_GETCURRENTSCINTILLA, 0,
                                                     ( LPARAM )&which );
                                      return ( which == 0 ) ? nppData._scintillaMainHandle :
                                             nppData._scintillaSecondHandle;
                                  }
                                  
                                  [,...]
                                  
                                  int start = (int)::SendMessage( getCurScintilla(), SCI_GETSELECTIONSTART, 0, 0 );
                                  

                                  This way, I can dynamically get the currently selected Scintilla view (1 or 2).

                                  As for your code, it works for me with following NppExec mock-up:

                                  SCI_SENDMSG SCI_TARGETWHOLEDOCUMENT
                                  
                                  SCI_SENDMSG SCI_GETSELECTIONSTART
                                  SET LOCAL START = $(MSG_RESULT)
                                  SCI_SENDMSG SCI_GETSELECTIONEND
                                  SET LOCAL END = $(MSG_RESULT)
                                  SCI_SENDMSG SCI_SETTARGETRANGE $(START) $(END)
                                  
                                  SCI_SENDMSG SCI_SEARCHINTARGET 11 "xml version"
                                  ECHO START=$(START) END=$(END) ==> $(MSG_RESULT)
                                  

                                  Running that NppExec script on the following file with NO highlighted text:

                                  hello there
                                  xml version
                                  goodbye there
                                  

                                  returns:
                                  START=38 END=38 ==> -1

                                  and if I highlight the whole document, it returns:
                                  START=0 END=38 ==> 12

                                  I think you may be able to simplify and not bother getting the start, end and SETTARGETRANGE and instead just use a call to SCI_TARGETFROMSELECTION

                                  Cheers.

                                    Your search string is ANSI (const char *) but your file is Unicode?

                                      As said earlier, npp does also use SearchInTarget therefore it could be
                                      that npp sets flags which aren’t useful in your case.
                                      For example, having a flag SCFIND_WHOLEWORD might conflict with
                                      your “xml version”.

                                        I will try and use SCI_TARGETFROMSELECTION. I am not sure what you mean by, “Your search string is ANSI (const char *) but your file is Unicode?”. I am very new to this all, so thanks for the help

                                          this is actually a very advanced topic and MUST be understood by
                                          every programmer which handles text.
                                          I suggest reading this and you have to understand, that Windows API,
                                          internally, handles everything with UTF16 and that a char pointer is start of your nightmares. :-)
