Creating VS debugger add-in for viewing DataSet/DataTable

[MuZZy]

Hi,

I'm developing an add-in for Visual Studio which works like Quick Watch in debug mode for viewing
datasets/datatables as tables.

I already have a working add-in, but there is one problem i can't find solution for:

When i select a dataset object and from context menu choose "DSWatch" (my add-in), it shows
correctly, but i need to add functionality to just put cursor on the variable instead of electing it.

What i have is:

public class Connect : Object, Extensibility.I DTExtensibility 2, IDTCommandTarge t,ICallback
{

public void Exec(string commandName, EnvDTE.vsComman dExecOption executeOption, ref object varIn, ref
object varOut, ref bool handled)
{
string str="";
DatasetWatchFrm _DatasetWatchFr m = null;
try
{
EnvDTE.Debugger debugger;
debugger = applicationObje ct.Debugger;
applicationObje ct.ActiveDocume nt.MarkText;

TextSelection _TextSelection;
applicationObje ct.ActiveDocume nt._TextSelecti on =
(TextSelection) applicationObje ct.ActiveDocume nt.Selection;
str=_TextSelect ion.Text ;

if ( commandName != "DSWatch.Connec t.DSWatchNode")
{
m_bDataTable = true;
}

_DatasetWatchFr m =new DatasetWatchFrm (str);
string strValue = this.GetExp(str );
_DatasetWatchFr m.m_strValue = strValue;
_DatasetWatchFr m.SetParent(thi s);
_DatasetWatchFr m.getXml(strVal ue);
_DatasetWatchFr m.Show();
}
catch(Exception e)
{
_DatasetWatchFr m.Show();
System.Windows. Forms.MessageBo x.Show(e.Messag e );
}
}

}

So i can get the selected text from IDE and then get the dataset itself,\but how do i get the text
under cursor?

Any suggestions would be highly appreciated!

Thank you in advance,
Andrey

To get the text under the cursor, even if there is no selected text, you use
TextSelection.A ctivePoint, create an EditPoint and then get the text with
EditPoint.GetTe xt or EditPoint.GetLi nes. You will have to parse the text to
the left and to the right until finding a blank character.

Thanks a lot! I will give it a try!

By the way, do you know any good tutorial/website dedicated to creating debugger add-ins?

Thank you

If i use EditPoint.GetTe xt, i need to specify number of characters.
So do i just set a big number of characters?
Like:

string strBefore = EditPoint.GetTe xt(-100);
string strAfter = EditPoint.GetTe xt(100);

and then look for space in strBefore starting from end and in strAfter starting from start?
Is it the right way?

Also, for c++ document case, should i include '->' or shoud i replace them by '.'?

Thanks a lot!

Not specific to debugger add-ins, but on my web page you have most (all?)
resources about .NET add-ins:

In my add-in I am using EditPoint.GetLi nes() with a line count of 1, rather
than GetText. So, I get the whole line of the cursor. Since I know the
column of cursor in that line, I can move to the right and to the left until
I find a blank character.

My C++ is rusty, but I think that "." was for structures and for classes
"p->f" was a shortcut for (*p).f . Ask in the C++ newsgroups or try and the
compiler will tell you if the syntax is wrong.
