View 2 RepliesI have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
Me.table.Update(Me.FigsDataSet.table)
Me.Validate()
I am working on a huge multiform project for my company, and one of the few issues I am having is that when I am on the Main Menu Form, then go into a specific form (i.e Sales Order, etc.), do updates, changes, or just view data then close the Sales Order Form, if I happen to go back into the Sales Order Form without closing the entire project, then the Sales Order Form will display data instead of opening a blank form like when I first opened it.
Is there something that I should be adding to the Form Close Event to dump all of the data or refresh the data adapters so that if I open the form again, it will display a blank form that is ready to be used like when I first opened it?
I have tried using;
Me.Dispose()
Me.Close()
when closing these subforms, but if I open them again, the data fields (combo boxes and text boxes) will have random data in them.
I have two textboxes...on the textchanged event of one textbox, readonly property of other textbox gets defined...e.g. first textbox is retrieving data as add,update,delete...when the first textbox text is changed to update then & then only second textbox readonly property is set to false...Now the problem,I am facing is....whenevr first textbox text is add,delete,its working fine..& second textbox is fetching the correct data..but once first textbox data gets changed to update,second textbox data remain unchanged though its readonly property gets changed correctly..it shows the same data as it was showing the first time when first textbox was changed to update...but after that,its data is not changing.

View 2 RepliesThis looks like an easy fix but I can't figure this out. I'm trying to have button click event on a subForm (NewTournament), add a record to a database, and then to notify a data grid which lists the records from the same database automatically (the grid is listed on HomeForm).I so for am able to update the database and call upon a new window. But I can't get it to refresh that datagrid for anything. I know I'm supposed to clear the datagrid, get changes, then refill the grid. But everytime I do this, the code is NOT updating. Furthermore, I can very well see that the record is being added.

I have some processes that run as a background job, allowing a user to continue to use a page, when the jobs are finished (which can take a few minutes) i want to display a message to the user, the best place to display this would be the masterpage AFAIK (incase they move from page to page on the site) so i have defined a div in the masterpage file.
I am trying to find the best method for displaying the data, at the moment i have a method in the masterpage vb file which polls a database to see if the job(which involves complex logic and some db access) has completed, if it has, it shows a message in the div e.g. "Job 13132 has completed" - which works fine.
The problem is this is not dynamic, and i have to refresh the page to call the function that checks if the processes have finished, how can i use AJAX to deliver this content automatically every 5 seconds?
I have tried using an asp timer with a 5 second tick time but the entire page refreshes on the timer click event every 5 seconds.Protected Sub Timer1_Tick(Byval sender as Object, Byval e As EventArgs)

Is there a way to only refresh the div with the updated message, without a full refresh happening using this code? Or if this is not possible, is there any way to replicate the above function using jQuery and still be able to update the DIV text only if a job as finished?
I have an APP that reads data from MS Access tables. It all works fine except that the numbers in Access table are formatted like 800001 so when the user puts "2" in the access table, it changes to 800002 and so on. I want to read the data AS THEY APPEAR in VB.Net but it reads them without the special format. So I get 1 or 2 etc.
I know how to format the data within VB but I don't want to hard code that as the format in MS Access might change. Is there anyway I can read the data format in MS Access ?

I have two dropdownlist, one is State and one is City. When a State is selected, the City dropdownlist becomes populated. At that point you can select a city, however if you select a city and go back and select a different state, the city dropdownlist is populated by the cities for both states. How do I get it clear the cities for the first state?

I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated. The card numbers are in a combobox (which are retreived from an SQL database using the DataAdapter), and each card has a boolean 'confiscated' field in the database.

have a main form that displays a users score.I hide the main form when going to a child form.When that child form is closed, it will show the main form.The problem is that the datathat has been changed when going to the child form is not displayed on the main form since it has not been closed.Is there anyway around this?
View 1 RepliesI'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated.
The card numbers are in a combobox (which are retreived from an SQL database using the binding source which is linked to a data adapter), and each card has a boolean 'confiscated' field in the database.
It does actually set the card to confiscated after the 3 tries, however I'd like the form to 'refresh' so the card no longer appears in the combobox, without having to close down the form and reload it. Is there a way to do this? I've tried refreshing the combobox and data adapter (.Refresh) but this does nothing
I load up a datatable - bind it to a binding source and a binding navigator - and lots of textboxes on the screen bound to that as well.When I get a concurrency violation - another user has already changed my vendor, let's say - what is the best method to go about refreshing the datatable with current data from the DB?
View 10 RepliesI have a VB2008 application that uses SQL Server 2005 Exspress Edition. I was modifying my application and then decided to add a table to the mdf (named "Pipe.mdf"), which I have don many times before, but I must have messed something up when I made other changes. After I added the new table I opened the Dada Source Configuration Wizard to add the new table to the dataset and I don't see the new table to select it. However, it added a copy of "Pipe.mdf" and named it "Pipe.mdf1" to the Server Explorer.
If I delete this copy of the mdf, it appears again in the Server Explorer when I open the Data Source Configuratuion Wizard.
If I add a Table to the copy of the mdf ("Pipe.mdf1"), it shows up in Dada Source Configuration Wizard.
what to change so that the new table appears in the Data Source Configuration Wizard for the original mdf (Pipe.mdf) and not add the copy of the mdf?
I have been trying to do this for ages and having no joy whatsoever.
I have a ribbon window of the following hierarchy:
MainWindow
MainContent (Tab Control)
TabContainerViewModel
ViewModelBase
View model base has an ObservableCollection of tabs type ViewModelBase. The Tab Control itself is binding fine to these, displaying appropriate view models. I have 2 problems however, I want a "NotepadView" (Of type viewmodelbase) to be replicated numerous times (one view many view models).
At the minute, I have 4 views (NotePadViewModelx where x is 1-4) with corresponding viewmodels, this is because each view had the same text per tab. Now I have individual views per tab.
When I type into tab 1 and switch to tab 2, I lose what I typed in tab one when I click back.
I have a small doubt: (VB.Net 2005, MS-Access 2007)Is it possible to add the current row from DGV to DB as soon as the row lost its focus..i.e. whenever i add a new row in DataGridView it should automatically get inserted into the database without pressing any buttons... Bcoz i need to add more new rows dynamically & hence i find little difficult in clicking the ADD button again and again to insert each and every Record.

Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.
