Easy String concatenation like Java using '+' at least in API's like Message Box etc.

[MAPJ]

I was operating on Pop-ups,I felt need of feature like java.

In Java when we have display Message we can easily concatenate variable with message string by using '+' sign.

Ex.

    In LabWindows,when do message pop up,

   {

    int var = 3;

    MessagePopup("Message count","Message No : "+var);

    }

     such a feature should be there.otherwise we do some string operation then Display message like " Message No : 3".

    So it increases string operations and string operations gives problem in memory management.

So at least In API's such '+' sign for concatenation of string with variables should be available.

Even if it is C language supported.

I don't think this would be possible while maintaining a C API.  What may be possible would be something like this where the pop up functions would be combined with the Fmt functions:

int MessagePopupFmt(char Title[], char Format_String[],...);

Allowing things like:

MessagePopupFmt("Notification", "%s<The measured voltage was %f +/- %f V.", value, valueerr);

Yes this solution will be good .hope it would be implemented!!!

Hi,

a more general message popup certainly can be convenient because right now probably everyone is using his own functions for formatting and display.

However, for consistency I would suggest the ANSI version, i.e. use the formatting options of sprintf instead of Fmt, see the discussion here

I agree with Wolfgang and I kudo the ANSI version (sprintf and not Fmt)

I'm sorry, I don't get it. This feature request is three lines of code you can write yourself, why wait for NI to implement it?

int __cdecl MessagePopupf(const char *title, const char *fmt, ...) 

{
    char msg[1024];
    va_list va;

    va_start(va, fmt);

    vsnprintf(msg, sizeof(msg), fmt, va);
    return MessagePopup(title, msg);
}

Is this solution available now??
