When viewing a dates Kind property in the watch windows the value "unspecified" will always be return regardless of the actual value.I'm kinda guessing this could be more of a general bug relating to the quick watch window evaluating the shared "Date.Kind" property rather than the specific date instances property.

My colleague and I have recently upgraded our projects from .NET Framework 1.0 and VS2002 to .NET Framework 2.0 and VS2005. We also applied the latest VS2005 service pack.
Our problem: normally when debugging we use the QuickWatch window to drill down into and view collections of objects belonging to the parent object we are "watching". THIS NO LONGER WORKS...instead, we get a message in the value line against the object collection saying:"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."This is incredibly frustrating, particularly when we have large nested collections of objects.We are pretty sure this feature was working fine after we upgraded, but we are not so sure that it was working after we applied the VS2005 service pack.
I receive a System.Data.SqlClient.SqlException in the following code: Specifically Incorrect syntax near ' In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. The exception detail in its entirety is shown below the code.

View 1 RepliesI'm trying to go through a DataTable, checking each row against a database to see if it is a duplicate or not, but all my comparisons show they aren't even though some are. I noticed when I look at my datarows, on Items that should be Null the value is {}. If I put that into a SQL Parameter, will that equal Null, or some kind of empty string?
View 8 RepliesWhen in the degug mode stepping through code a line at a time, I want to monitor a variable that was created public on another form. It adds the request, but won't shoe me the data. It says I have to ahve an object reference. I don't know what it wants exzactly or how to give it. Here is an example:
I have on form 1 one a variable, Crec. I am in the debugger debugging code in form 2. To access the variable on form one in my code on form 2, I have to use this syntax: form1.crec Now when I put this quickwatch request in, while debugging form 2, it will not let me see the value for form1.Crec It says I need an object reference. Can you tell me I am doing wrong and how to correct it? I'm sure it something simple.

View 1 RepliesWe generated a class from an XML file a while back. I think we used xsd.exe.
One of the main node collections in the XML file was rendered as:
<System.Xml.Serialization.XmlElementAttribute("PRODUCT")> _
Public Property PRODUCT() As PRODUCT()
Get
Return Me.pRODUCTField
[CODE]...
And sure, there's PRODUCT class defined later on, and it worked fine. Serialized and deserialized fine. Didn't need to worry about it or manipulate it. Only now we have to revisit and manipulate the data.
But what kind of collection (array?) is Public Property PRODUCT() As PRODUCT(), and how do we loop over it? And add to it? Basic question, I know. Probably got too comfortable with generics and now xsd has thrown something at me which isn't List(of T) I'm running scared.
I have just run into an issue of screen flicker that I haven't been able to solve. I have a panel with dozens of controls on it. Painted onto the panel, behind the controls, are a few colored rectangles.
Those rectangles flicker whenever the mouse is moved over any control, or off the panel. Basically, a paint event for the panel is raised whenever the mouse leaves the panel.
Therefore, I thought that if I only painted the rectangles when they needed to be painted, not every time the Paint event was raised, that I would be able to avoid the flicker. After all, there is no obvious reason why they would need to be re-painted just because the mouse moved over a control on the panel.
the paint event was still being raised, and the panel just wasn't painting the rectangles, so they weren't being drawn at all (but they sure didn't flicker). So, the flicker is being caused by the fact that the paint event clears the panel, which gets displayed in a cleared state for a fraction of a second, then the rectangles are drawn in.
Doublebuffering the form has no discernible impact, which may well be because the screen draws the absence of the rectangles on one frame, then draws the presence of the rectangles on the next frame. They both get shown in sequence, so the rectangles appear to flicker badly.
One obvious alternative is to not even draw the rectangles, which works great, and they are only useful visual guides, not essential components. Still, that doesn't seem like a good solution.
So what I am looking for is a way to supress the display of the undrawn image before showing the finished image.

so pseudo code on a button click at the moment i have a function that returns this variable
label1.text=myfunction.getName()so this works fine , It seem ugly to have some kind of sleep function that loops every couple of seconds to run myfunction.getName() every 2 seconds , as a bit of a newbie , I am just wondering how I can set up a function that basically says 'when myfunction.getName() changes , then change label1.text'
