I'm testing a window application which was written in VB.Net 2003. I set a few BreakPoints and Debug the project. When the debugger hit one of the breakpoints, it http://www.vbforums.com/showthread.php?585708-RESOLVED-Error-cannot-obtain-value-in-Watch stops at there. Its correct. But when I try to add one of the variables to "Watch", it said "error: cannot obtain value". I tried to search the Net and found that some said "its because of structures", some said "its because of passing too many parameters." and some said "its because of too many line of codes (LOCs)". but my problem is not in passing parameters or too many line of code. the function i set breakpoint has only around 300 LOCs (including around 100 line of comments) And the value I tried to get is from my TreeView which is on my Win Forms. its very strange that I can't even get the value from Forms. I assign this TreeView value to another TreeView (this one is declare in code.) And this second TreeView also can't view Watch. What can I do for that? Any suggestions or any fixes? I'm using Visual Studio 2003 in VB.Net with SQL Server 2000 for the above project. Thanks. I'm using VS 2005 & 2008 & 2010 with SQL Server 2005 Express.

It compiled fine but it wasn't evaluating the value of one of my dropdownlists (ddlMB.SelectedItem.Text). When I put a watch on cannot obtain it I get this error... error: cannot obtain value This was working a couple of weeks ago and as far as I know nothing has changed. The strange thing is that the value of the dropdownlist isn't being evaluated properly on our testing box either so I don't think it is related to VS 2005 or my local IIS. Has anyone else ever experienced this error? I cannot obtain value don't know how to begin to resolve this. Thanks. Reply RajeshDev None 0 Points 3 Posts Re: error: cannot obtain value Aug 19, 2006 01:03 AM|RajeshDev|LINK Seems like ddlMB type has changed from DropdownList. You can delete and add a new control with the same name and see. Are you able to watch "ddlMB" if so then try adding watch on "ddlMB.SelectedItem" and see whether you are getting not null reference.

Post your question and get tips & solutions from a community of 418,506 IT Pros & Developers. It's quick & easy. {length=error: cannot obtain value} P: n/a Dominiek Hi, I have a strange problem. during the developement of my program, while progressively writing more and more code, the callstack of my program gets deeper and deeper (7 levels). Then, all of a sudden, when calling a Sub with 2 parameters, a Hashtable(19 items) and a ArrayList(9 items), the value of these variables is gone, the debugger reports the value as {length=error: cannot obtain value}. Passing them ByRef does not seem to solve the problem. IMHO, this seems to be a problem with the stacksize. Could somebody please help me with this? TIA Dominiek Nov 20 '05 #1 Post Reply Share this Question 5 Replies P: n/a Armin Zingler "Dominiek" schrieb during the developement of my program, while progressively writing more and more code, the callstack of my program gets deeper and deeper (7 levels).

Passing them ByRef does not seem to solve the problem. IMHO, this seems to be a problem with the stacksize. 7 levels is for sure not a problem with the stack size - unless you've got really many local variables. Apart from this, you should get a StackOverflowException. I also had this problem, but *only* when using certain functions in the managed DirectX assemblies. It's been forwarded as a bug to the dev team. I guess you are not using managed DirectX? If you don't use it, sorry, I don't have an explanation. You could narrow the problem down to as few lines as possible and post it to microsoft.public.vsnet.ide or microsoft.public.vsn
