How my code works when I want to update I see the changes in the textbox when I do my movelast, movenext. but when I go to the database the changes are not there can someone help I am using vb.net 2010 and access 2010If you think it you can achieve it
I have an inputbox with ok cancel buttons in my class.The user should fill in numbers in the inputbox and if nothing is entered and the user presses cancel or ok, the user get's a msgbox that he should enter something and after this the inputbox should show up again until something has entered.
I now have the following code:
Dim answer As String Dim amount As Integer Dim result As DialogResult
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
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.
I know its .net but i am still using ADODB this is just a sample table, not really what i am doing..I want to take a look at a bunch of records until the customer changes. then i want to have the previous recordset data displayed or passed off to another function how do i set RS2=RS but when i "movenext" RS RS2 still holds the previous record data? [code]
I have been trying to implement the jQuery weekcalendar using .net. What I can't seem to figure out is why weekcalendar states events.events is undefined after I make an ajax call to a webmethod I created which returns JSON. Below is the relevant code:
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. [Code]
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.
I was hoping somebody out there could help me please, I have an application which uses threading, process and runs cmd.exe - the problem I have is that I cant cancel the command.I have one textbox and two command buttonts, button 1 is run and button 2 is cancel - for this testing purpose only (my app wont be pinging but I'm doing this for testing only) I'm hoping to enter an I.P address in the textbox and then click on Run which starts a thread and the process, which so far is working.the coding I use to run the command is.[code]Now comes to difficult part, whilst the command is running I want to click on cancel which kills the thread and process which I have done but I have hit a brick wall because even though my thread and process has been killed my command carried on running, what I would like is the moment the cancel button is clicked to kill the thread, process and the command.
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.....
I have been working/coding with e.Cancel, e.EventArgs, etc without knowing what the "e" stands for. Can I have a simple explanation of what e means and possibly similar concepts in VB.Only performance counts!
How do I add a cancel button to a message box? I really need to know this because it is kinda stupid that i have a message box saying "Are you sure you want to clear everything?" and have no cancel button. Also what code do i need to make a program key where it is made so that I give a key and it works with that specific program another one will be made with a different key. I have no code for that because i have no clue where to begin (3 day trial code so it is locked would be nice to) The other problem I have is makeing the program open new windows so if i click trial then it will run for 3 days then done and with code making it run forever without the pop up again so how do I do all that?

How can i catch the return of say an OpenDialog/Save Dialog/Color dialog?
For example i want to know if the OK or Cancel button was pressed and use a goto statement that jumps to a section of code that exits the sub to avoid an error (especially in the case of pressing cancel when using an open dialog).
If Not IsNumeric(textbox1.Text) Then KeyAscii = 0 End If I learned in MSDN and wrote those code,but it doesn't work. This code " KeyAscii = 0" it's not correct, I just want to cancel the input, for instance,if user input 1a, then "a" will be not inputted into textbox, but "1" will leave.
Is there a way to get the even when a user presses an OK button or cancel button? In the Windows.Forms.DialogResult.OK only assignes a value for the OK or Cancel. However how do I get the actual value pressed by the user. In other words how do I know whether the user presses the OK or Cancel button?
I could add a contect menu strip to it but I feel that this wouldn't serve as a good interface for users not familar with the system...Also I would like to give the user the ability to click away from the DateTimePicker and instead of it closing and saving the value, I would like the value cleared On my close up event I have a event handler to store the chosen value to the database so I still need to maintain this funcitonality.
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:
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 ?

I've run into a bit of an issue. Sometimes a user starts a search, but doesn't want to wait for the search to finish because they thought of some change they want to make or because the search is taking too long.
How would I cancel a Search? I understand that I would have to run the Search on a separate Thread. Would I just abort the Thread? Or do I need to send SQL Server something to let it know that it can cancel the query?
