Visibility of work areas, variables, viewing contents of objects

Post by wriedmann »

Hi Thomas,
yes, they are the references of your application.
Personally, I would add a call to the debugging functions somewhere in your menu, so you can call then whenever you like - even when the application is running on another machine than yours.
But of course, if you add that library to the references, you have to deliver the relative DLL together with your application.

Visibility of work areas, variables, viewing contents of objects

Post by ThomasWYale »

Hi, Chris.

I tried it and it works. DbgShowMemvars produces an RTE, but the only other downside is that DbgShowGlobals and I think I may have a solution for that.

I was thinking of building a dialog, using one or more global variables or objects as arguments, and constructing a class which uses Object2Array() along with IVarListGetInfo(), IVarList() and IVarListClass(). This class implemented in the dialog would traverse the array and add treeview items with data derived from these functions. It would check the type with IsString(), IsSymbol(), IsLogic(), et al to display the values, iterate the element if IsArray(), and in cases of IsObject(), an object within an object, call the method for accessing the object element recursively.

When I get it to work, would you like me to share the code with you? I don't know whether it would make emulating CAVO's global treeview for objects in XIDE any easier, but if it does, I'd be glad to help.

Hi Thomas,

Yes, please send us the code, if it's suitable it can be used in both XIDE and VS!

We are working on this at this moment, as well as an improved "Debugger Expression Evaluator" (both for the VS debugger, the XIDE debugger is another thing).

I am not sure what you mean with RTE, but if it is an exception, can you please share that with us, so we can take care of it.

Robert,

It gives a runtime exception, this is why I did not include this function in my post above

Code: Select all

System.InvalidCastException
Unable to cast object of type 'System.Reflection.RtFieldInfo' to type 'System.Reflection.MethodInfo'.

Callstack : 
XSharp.Debugger.MemVarsWindow.System.Void XSharp.Debugger.MemVarsWindow.LoadValues()() 
XSharp.Debugger.MemVarsWindow.System.Void XSharp.Debugger.MemVarsWindow..ctor()() 
static System.Void XSharp.RT.Debugger.Functions.DbgShowMemvars()() 
Also DbgShowWorkAreas() gives some handled exceptions, looking into it and will open tickets if necessary.

Here you are, Chris. I would've finished a lot sooner, but I have a day job, had to contend with walking a few miles to work every day in the wake of a recent snowstorm, among other things.

I tried to emulate as closely as possible to the way VO 2.8 does this. Like the functions in XSharp.RT.Debugger, it has to be either inserted within the code or called from a menu option. As long-time VO 2.8 users know, however, the feature seems to use a kind of hybrid control with the properties of both a listview and treeview. Since I didn't have that, I settled on a treeview instead. And since I can't include the actual form here, you need only construct one yourself with the two PROTECTs as listed in the class declaration for ViewObjects. One or more GLOBALs, or any combination of objects or arrays to be inspected, are included in an array designated as uExtra argument in ViewObjects.

Code: Select all

LOCAL oViewObjects AS ViewObjects
...
oViewObjects:=ViewObjects{,,,{<arrayOrObject1,arrayOrObject2,...}}
oViewObjects:Show(SHOWCENTERED)
Early on I figured that I'd face the problem of a stack overflow error if I constructed a complete tree, particularly if there were circular references, so I put in safeguards prevent that. As in VO, a user double-clicks a node to reveal its content, but the tree adds items only incrementally, revealing only what the user intends to see. That way, the tree indicates the presence of any array elements or object attributes one step in advance, with the [+] designation beside the node as unexpanded.

I tested it as extensively as I could, and hope that you find use with it.
