Middle Mouse button - Now unrecognised

New comment
 

Hi Guys, 

I have a function tied to my middle mouse button.

Up until about an hour ago my middle button function was working, now it's not being recognised at all. 

I've got the following code to recognise any chart events to print their respective ID's out:


   if(id==CHARTEVENT_MOUSE_MOVE)
      {
      
         Print(lparam);
         Print(sparam);
         Print(dparam);
        }


Now nothing appears when the middle button is pressed. I know the mouse button works, i've tested and confirmed. Is anyone else about to see if they get a response from a middle mouse button click? Or point me in the direction of why this might be?

Thx

Build 3500 was updated today.

Did you notice if the issue occurred before or after the update to build 3500 occurred?

Try the previous build and see if the issue still occurs or not.

Try the previous build and see if the issue still occurs or not.

It happened just before the new build was released, i remember downloading the latest version in the hope it would fix the issue. 

I'm happy to try a previous version, do you know where i could find it?

 

Thanks to Andrey Khatimlianskii, you can download previous builds here — https://drive.google.com/drive/folders/1YSUVehcElTpLxCLPMsdlDfFu4Y61yrcc

However, probably to the war in the Ukraine, he has not been adding the more recent updates but is up to build 3446 there.

My previous build was 3491, but I'm not able to attach the ZIP file here or send it to you via private message due to the 16MB file limit.

Try the 3446 build first from the link above, just to see if it works, and then we will take it from there.

 

If however, build 3446 does not work for you, please supply a small simple demo code that can be compiled and tested on our end to see it reproduces the issue.

 

Also, remember to keep backups of your files, especially build updates, so that you can revert when things go wrong.

Backups in general is something that you should be doing regularly anyway to safeguard your data.

Good to know, MT4/5 is new to me, so i'll do this for future reference.  Unfortunately, i could download the files, but couldn't install, i tried multiple instances, all the same result.

Here is test code that should print on any mouse movement on the chart, more specifically, print, if the middle button is clicked:

   if(id==CHARTEVENT_MOUSE_MOVE)

         if(sparam == DoubleToString(16,0))
         {
            Print("Middle Button clicked");   
         }
         
      }
   }

Hopefully you see something!

Thanks

 

I created the following test code and ran it on build 3500 and it successfully reported the three regular button states, including the middle button ...
