I am new to .net and am wondering what Index is in .net. In vb6 I could set a index value to any object and then duplicate them and use the same code. Does .net have something like this?
View 3 RepliesI am trying to get an index of a List(Of Details) Details being a class i use instead of an annon method. Is it because i am using array.findindex when it's not an array but a list(Of???
Dim index As Integer = Array.FindIndex(Details, Details.FirstOrDefault(Function(nd) nd.Name = "name"))
Error1Data type(s) of the type parameter(s) in method 'Public Shared Function FindIndex(Of T)(array() As T, match As System.Predicate(Of T)) As Integer' cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.
I have a datagridview with 3 columns. The second column is a combobox which I want to bind with a dataset. How do I go about setting the column index for it as I am doing something like this.
Dim ComboCol As New DataGridViewComboBoxColumn
ComboCol.DataSource = SDS.Tables(0)
ComboCol.ValueMember = "Specie"[code].....
I dont want to be setting the index positions and lenghth to a specific number becuase when i choose a different name from the listbox that is at a different position or longer it wont display it properly. explain to me another way around this so as it will allow any details to be selected and read???

In Windows 7 you can pin a program to the taskbar so it appears like a quicklaunch item. In my program I need to get a list of all the programs that are pinned to the taskbar. Does anyone know how I can do this programatically, either through an API call or through a registry setting?

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
View 3 RepliesI am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?
