Find and replace is not working for vs extension custom editor in VS2022

Question

Find and replace is not working for vs extension custom editor in VS2022

Soumabha Sarkar 41

Find and replace is not working for custom editor in VS2022. It works in VS2019. We have implemented IVsFindTarget for our editor.

In fact, once I click Find Next, none of the IVsFindTarget methods are getting hit and it is not able to find the search word from the text.

Ideally when I click Find Next, IVsFindTarget.Find method should be invoked. Please correct me if I am wrong.

The view has the implementation of the following interface

IVsWindowPane,IVsStatusbarUser,IVsFindTarget, IVsFindTarget2,IVsTextImage, IVsTextSpanSet, IVsTextBuffer, IVsTextView, IVsCodeWindow,IVsTextLines, IVsDpiAware

Hi @Soumabha Sarkar , welcome to Microsoft Q&A forum. Could you share me some code snippets about how you implement IVsFindTarget, and is the code that used in VS 2022 the same as when it works in VS 2019? Is there anything changed?

Hello @Tianyu Sun-MSFT , the code used in VS 2022 is same as when it works in VS 2019. There is no change. I can share the code snippet but what method implementation I should share. I have debugged the code and found that only 3 methods of IVsFindTarget are getting hit.

Hi @Soumabha Sarkar , could you share this 3 methods with me to check? And I think you can share the implementation of following method: NotifyFindTarget(UInt32).

int IVsFindTarget.NotifyFindTarget(uint notification)  
    {  
      return MyEXTCom.S_OK;  
    }  
  
  
int IVsFindTarget.GetCapabilities(bool[] pfImage, uint[] pgrfOptions)  
    {  
      // We do support IVsTextImage  
      if (pfImage != null && pfImage.Length > 0)  
        pfImage[0] = true;  
  
      if (pgrfOptions != null && pgrfOptions.Length > 0)  
      {  
        pgrfOptions[0] = (uint)__VSFINDOPTIONS.FR_Backwards;        //Search backwards from the insertion point  
        pgrfOptions[0] |= (uint)__VSFINDOPTIONS.FR_MatchCase;       //Match the case while searching  
        pgrfOptions[0] |= (uint)__VSFINDOPTIONS.FR_WholeWord;       //Match whole word while searching  
        pgrfOptions[0] |= (uint)__VSFINDOPTIONS.FR_Selection;       //Search in selected text only  
        pgrfOptions[0] |= (uint)__VSFINDOPTIONS.FR_ActionMask;      //Find/Replace capabilities  
  
        // Only support selection if something is selected  
        if (UIVDocView != null && UIVDocView.SelectionLength == 0)  
        // if (editorControl.RichTextBoxControl.SelectionLength == 0)  
          pgrfOptions[0] &= ~((uint)__VSFINDOPTIONS.FR_Selection);  
      }  
      return MyEXTCom.S_OK;  
    }

Hello @Tianyu Sun-MSFT , I have posted the code snippets in the comment section for reference.

Hello @Tianyu Sun-MSFT , we debugged the issue but were unable to find the root cause of the problem. Please advise. I have already shared the code snippets in the comment. Please let me know if you need any further information.

Hi @Soumabha Sarkar , above three methods look good. Did the NotifyFindTarget method return S_OK instead of error codes when it got hit?

@Tianyu Sun-MSFT , We are always returning MyEXTCom.S_OK from NotifyFindTarget method. So, NotifyFindTarget method will always return S_OK when it gets hit. Please correct me if I am wrong.

public const int S_OK = 0x00000000 int IVsFindTarget.NotifyFindTarget(uint notification) { return MyEXTCom.S_OK; }

Also, after I click Find Next button, what methods should get invoked?

@Tianyu Sun-MSFT , is the NotifyFindTarget method implemented properly in our case. Please let me know. Also, if we know what method should ideally get invoked after clicking Find Next button, we can verify that in our case as well.
Also, once I click the Find button, input parameter notification is coming as 7 & 9. But according to MS documentation, this notification values are taken from the __VSFTNOTIFY enumeration which are

0 This target has become the current target

3 The find/replace operation is complete

1 This target is no longer the current target

2 A find/replace operation is about to start

Also, we intended to support IVsTextImage by making pfImage[0] = true in IVsFindTarget.GetCapabilities method and we have implementation for IVsFindTarget.GetSearchImage method.

We tried to change the pgrfOptions to __VSFINDOPTIONS.FR_All in IVsFindTarget.GetCapabilities method but it did not work.
