C# question

Post #403,616 by lincoln 7/24/15 11:31:12 AM Reply	C# question I was just given a program to support, but first it has to be compiled. The original author is no longer here, so I can't ask him what he was thinking of when he wrote this statement: MyProject.Forms.frmAddAction.lblTgrID.Text = Conversions.ToString((!0)MyProject.Forms.frmStatus.TriggerTableAdapter.GetID()); The compiler highlights the word MyProject after the "(!0)" and the error message is ") expected". What does the "(!0)" mean in this statement - is it for formatting the ID number?

Try removing the (!0) text and seeing if it compiles. If so, there may be something wrong with the formatting of the instruction (e.g. maybe another set of parentheses are needed or something). Otherwise, the standard debugging steps of "insert print statement" as needed may be the quickest way to figure out what it is doing. HTH a little. Good luck. Cheers, Scott.

It doesn't make sense syntactically (caveat: I'm a Java programmer much more than a C# programmer, but still). !0 would mean "not zero", or 'true', but putting that in front of a method call (MyProject.Forms.frmStatus.TriggerTableAdapter.GetID()) doesn't make any sense.

Looks like something got crossed up last time your predecessor saved the code. If there's a source code management tool involved, take a look at past revisions to see where this cropped up.
