Question

I (still a novice programmer) have been given 2 dlls to write a GUI program to view/change tags from a running software called InTouch:

• IOM.InTouchDataAccess;
• NDde;

Everything works well ; Read(string tagName) works, TagDotField(string) works well

and more… The issue is when I use the method Write(tagName, inputValue).

string inputValue = ValueBox.Text;
renamethisobject.Write(tagName, inputValue);
MessageBox.Show("Tag Successfully changed to " + renamethisobject.Read(tagName));

In the MessageBox, I made sure that the object gives back the changed tag, which it does. The problem is that in the InTouch program, the tag is not change. Why is that? Is it an issue in the dll ?

P.S. I do not have access to the dll definition, only its method names. Should I ask the programmer who did the dlls?

If you don’t have any documentation and asking the person who created the code doesn’t work out, you could try to decompile. http://www.telerik.com/products/decompiler.aspx
