Hello,

I have a question if it's possible to display the string part of a matrix in *.exe file created from a Smath file?


Screenshot of issue

Tried the var2string function, but after changing the string value via exe file, it reads function argument name (a) instead of it's value.

Is there some kind of workaround for this issue?

It would help if you post the original .sm file.

I'm not exactly sure what you are trying to do. Are you trying to assign a value to a variable name defined in a?
If so you can do something like this: https://en.smath.info/forum/yaf_postsm36117_New-variable-programmatically--also--Solving-under-over-defined-system-of-linear-eqautions.aspx#post36117

As far as getting that dynamically created variable name to display on the left as an actual variable name, I'm not sure if that's possible.

In smath it's defined as:

a:="sample string"

a="sample string"


And if I change the string, sheet recalculates and shows a value as the new string. I wanted to achieve this functionality in smath viewer in exe file for creating additional info page on my docs, like project name and so on.

Make sure you hit enter/return key after entering value.

Edit: You may have found a bug. This kind of functionality works great with numeric values but not with strings. I've tried with different optimizations as well to no avail.
I'm not sure it's ever worked. I now SMath Viewer is still a work in progress so feel free to add bug entry.

Hello Barmin


The function you are looking for was previously available in previous versions of smath, such as version 5737.
I do not know why they disabled it. Here I put an example in that version.

Martin,

Once the Viewer is running try to change the value of Hallo and notice if it doesn't update in the second box.

For me it works. Yet I have to press enter to forward the changes in the input box.

For me it will change the numerical variable but not the string one (with return pressing, of course).
