I'm working on a piece of code at the moment that uses an older style DataGrid to allow the user to enter information into the table. It already has an add and delete button. Currently the user enters information into 3 textboxes that are in the footer, and the other rows use labels to display the information.
Essentially what I am wanting to do is take the line that the user has clicked the edit button on, and move the text from there in to the footer (deleteing the row that it was displayed on) so the user can make changes and then click the add button again. At the moment I have tried using FindControls to find the textbox and setting the text that way but it doesnt like it.
So Let me explain the situation, I have a Mainpage Form with a DataGrid Object on it. I have a Create Post Form and I want to use the create post form to also edit a post. Now only individuals who posted a specific post can edit it. I have all the validation code in to check the user etc. I used a simple boolean and then in the create post form created two subroutines, Newpost and Editpost. I have the New Post working perfectly, but i can't get the edit post to work.
Dim startdate As DateTime = Departdate.Value.Date Dim enddate As DateTime = returndate.Value.Date MainPage.SelectedPost = DirectCast(PostBindingSource.Current, DataRowView)
Open/Edit/Delete is through below code Public conn As New OleDb.OleDbConnection Public da As OleDb.OleDbDataAdapter

I am displaying this data in a datagrid by connecting datasource and datamember.What i need is to displat a dropdown on second column in the datagrid. When i change the data it should update the database PBL (Visual Studio 2010 Ultimate)
I am trying updating a record. It seems like I did all the right things but I can't seem to update my database. I'm not sure if my update button is functioning as it should be.
Private Sub UpdateButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateButton1.Click Dim cb As New OleDb.OleDbCommandBuilder(da5) While count5 < MaxRecords5 cells5 = 0 [Code] .....
Whenever I edit the datagrid, and press update, it doesn't really update the database.
after editing my cell in the datagrid . i am sorting then i select the next record the selection was do to the 1 cell on the row .i don't know what is the problem
My application security from piracy depends upon fields in my databases. User has to activate the application, that writes Bought in my database. But the problem is if a new user installs my application and replaces all databases from some one who has bought key, the application also becomes active without buying key from me.
Is there any possibility that I could mark the databases to be recognized with the particular setup?
I've picked up some code from a colleague, and in one of his methods he has a boolean parameter: ByVal showProactiveChases As Boolean?. I had to look up the ? operator yesterday to see that it denotes a Nullable type. My question is, if I change it to: ByVal showProactiveChases As Nullable(Of Boolean), does the meaning remain the same? I think provided it doesn't change the meaning the second way is much more readable.
I had a need to mark a listview row if filenames were duplicates for n number of characters from the left. I wrote the following but it smacks of VB6.[code]...
I have developed an active x control and signed it with certificate. I know that digital signing is needed , so that the browser knows that the active x comes valid source.My asp.net form has a button , which invokes a method on activex control as -[code]....
But it errors on browser stating that the - IE has blocked this site from using an active x control in an unsafe manner. ( Please see attachment).So should I have to develop the active x control which implement IObjectSafety and also signed digitally, so that it can execute on client browser without any warnings from IE. Any examples.
I have a macro written in VB in Excel, which reads emails from Outlook. I would like to automatize this process, but everytime, when Excel wants to access the outlook, I have to give permition to do that, see http://apophis.wz.cz/permition.PNG (It's in czech, but you will see the point). Is there any way to give this permition for ever? Or for long time, such as 10 hours? (I can choose max. 10 minutes).

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs) Dim _CB As CheckBox = DirectCast(sender, CheckBox) Dim _ID As Integer = _CB.Tag Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice
I placed a datagrid in my form which l retrive data from my sql. i am using oledb connection. if i run the form i can retrive the data but i am not getting the data in the grid at first ,there is a "+" sign, i have to clik that then it shows the table name and after clicking the table name i can view the data displays in the grid..
I have a datagrid which I am using LINQ to fill, I then add some custom columns and fill them in programmatically - if the users clicks on the column header to re-sort, all the data in the added columns disappears. I am obviously missing something very basic here but can't seem to see the forest for the trees. I also have a couple of other questions about how I am doing things:
I am trying to create an xml editor that read and write xml. my code reads the xml with no problem and allows me to create new rows but when I try to "write" it over I get the following error: "Token StartElement in state Epilog would result in an invalid XML document"
here is my xml: <?xml version="1.0" standalone="yes"?> <MacroList identifier="test">
I decided to rewrite my project. Hit another snag. How do I write the contents from a datagrid to a file and back into the datagrid again later? (Actually, I've done the writing ok - but for the life of me can't get the data back into a blank datagrid.
Here's what I done so far:
Imports System Imports System.IO Imports System.Text
Basically,I had a button in my form1,when I click it,then form2 will be display...Now I would like to lock form2 until a button in form2 had been clicked,then only I can do anything in other forms...I means form2 must be closed before I can remain to form1.
I have a form and its filled from a VIEW of two tables on SQL server. When its opened i dont want other users opening that customers details from either table.I know SQL itself prevents writes if its opened but i want to stop people opening the record in the first place.[code]...
I then tried writing these values to the db on the form loading but it doesent work - it just sends back NULLs. I tried the same code in the on load event into a button and it works fine there. So im thinking i should do this as a Trigger on SQL itself, but im unsure how i could get the users computername or Windows Login name, or even username from the front end im building.
What I want to do is to lock the file so that no other process can use the file. If a process wants to use the file, I also want it to wait and try again until file is available.
