Hi,

I am having problems, figuring out how to make the filename a setting for the alert.

sc.PlaySound(SoundFileName.GetString(), 1);

is having problems, what must I do to make this work?

Thank you for your help on this.

You need to use the SCString data type.

Hi,

I tried this but with no luck....

sc.PlaySound("c:\\!TradeAlert_Sounds\\%s_Long.wav", EntryAlert_RootFileName.GetString(), 1);

You are not using the SCString type. Also, the function is called GetChars().

It is documented here:

I cant access a getchars from the SCInputRef... where I define the root file name... All I can do is the getstring. So my Buffer.Format line throws an error..

Here is code...



   SCInputRef EntryAlert_RootFileName = sc.Input[18];
...
...
...

    EntryAlert_RootFileName.Name = "Root File Name for Entry Alert";
    EntryAlert_RootFileName.SetString("QCL");
..
..
..
  
    SCString Buffer;

    Buffer.Format("c:\\!TradeAlert_Sounds\\%s_Long.wav", EntryAlert_RootFileName.GetString);

sc.PlaySound("c:\\!TradeAlert_Sounds\\%s_Long.wav", Buffer.GetChars(), 1);

Actually, I found out a way to do it, is this an appropriate way?



    if
      (
        (sc.DownloadingHistoricalData == 0) &&
        (sc.Index > sc.ArraySize - 5)
        )
    {


      char * RootFileName = new char[std::strlen(EntryAlert_RootFileName.GetString())];
      std::strcpy(RootFileName, EntryAlert_RootFileName.GetString());
      SCString Buffer;
      Buffer.Format("c:\\!TradeAlert_Sounds\\%s_Long.wav", RootFileName);


      sc.PlaySound(Buffer.GetChars(), 1);



    }

For a study input you do need to use the GetString function.


sc.PlaySound("c:\\!TradeAlert_Sounds\\%s_Long.wav", Buffer.GetChars(), 1);
The above line of code does not make sense. Specifically the use of "%s".

char * RootFileName = new char[std::strlen(EntryAlert_RootFileName.GetString())];
You are not allocating enough space. You need to allow for the null terminator. What you defined is dangerous and will lead to instability in Sierra Chart.

In general we strongly recommend doing something like this unless you really know what you are doing.

Ok,

I tried an alternate method, is this a correct way to achieve this?



      SCString Buffer;
    

    
      Buffer = "c:\\!TradeAlert_Sounds\\";
      Buffer += EntryAlert_RootFileName.GetString();
      Buffer += "_Short.wav";

      sc.PlaySound(Buffer.GetChars(), 1);
