BindingSource.MoveNext And MovePreviou Skips Records

Sep 17, 2009

I have a binding source that when I use the MoveNext or MovePrevious methods it skips records.  I've tried circumventing this by using Position ++  and Position -1 instead but I still get the same result.  I even resorted to manually sorting the binding source to see if that would help but no joy as well there.

I have a bindingsource that is tied to a dataset class.  I added 2 records to start and movenext worked as it should (moved 1 to 2) as well as move previous.  I added a third record and now the movenext method skips record 2 and moves straight to 3.  The same symptom also occurred for move previous. I also added a fourth record and it got even weirder.  As before when movenext was invoked, the record pointer moved from record 1 to 3.  I invoke MoveNext again and it moves to record 4.  Now I hit MovePrevious from Record 4 and it moves to record 2 skipping record three.

Others who are working on forms with different bindingsources ties to the same dataset class are seeing similar things.

Mouse Events And User Control - Control Won't Respond To The Events

Dec 31, 2010

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

Cancel An ASP.NET MVC Action?

May 12, 2009

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":

Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)


In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.

How To Cancel Thread

Jun 12, 2009

I am not familiar with threads, but the project I am working on has a bunch of them. There's a thread for the main form, then threads for activities like a calculation, converting files, etc, so that the user can kick off a calculation job and then kick of a conversion job that will run at the same time. Typically, calculations can run for hours and hours; conversions and other threads may only run a few minutes.If the calculation runs into a problem, how do I cancel that thread? It looks like the threads are controlled (driven?) by the main form, but I'm at a bit of a loss.....

Signal (NOT Cancel) A BackgroundWorker?

Mar 7, 2011

Is it possible to send information to a BackgroundWorker thread while it is running? Here is my scenario: Parent thread calls background thread to send a data request to a database. If it's a big complicated query it can take a while for the db to respond, so putting the db request on the background worker thread is great. My app can do other stuff while the one thread waits for the db.

Now, db responds with beginning of data. I want my background thread to report back meta data about the result set to the parent thread. No problem there, I can use a custom user state object and the ReportProgress method. But now, how to I send a signal from the parent thread back to the worker thread? I want the background thread to wait while the parent thread does something, and then tells the worker thread to keep going or quit. I know how to cancel a background thread, but I want the parent to be able tell the child some information other than "cancel". Here's one way to think about it:

Stop / Cancel A Build?

Jun 22, 2012

I went to publish a new version of my game to my C: drive, got the standard "Build Started" and thats as far as it got.Now I can't do anything with the vis studio program, if I try to save - a warning message tells me this is a bad idea with a build running, trying to exit the program results in a message "A build must be stopped before the solution can be closed".

Choosing "Cancel Build" in the build menu caused the Build Started to disappear but nothing else. All other options in the build menu are inacessible.

Searching the program help and google for how to stop builds give a lot of web pages that go on about the build explorer, found in the team explorer, select the team project, etc etc - I don't have anything in the team explorer window, this project is just me and my pc.

What happens if I use the task manager to shut the program down ?
