I declared an array of strings and initialized every element to "5". But when I debug with a breakpoint after the For-Each, all my array members have Nothing in them. I'm on Visual Studio 2010.
Dim words(999) As String
For Each word As String In words

In this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.
View 1 RepliesI'd like to, let say "declare" my custom command, and what do I mean by command is something you type in the code, when for example you click a button. Just like Textbox (for example), my custom command sould have "underthings" in it, so just like I can type in Textbox1.Text. And that underthing (in this example, textbox is my custom command and .text is a sub/underthing) I can set if it is a boolean or string etc. I need this for my login program, where that custom command is an username (named username, what you can dim), and then it has sub things, like username1.email (string for e-mail text) and username1.password, username1.ismoderator (boolean, true or false). So an example, in my program I can do like this:
'Username is my custom command, just I don't know how to'define or declare it.'Username has here, to keep it simple, 2 sub things, it is'username.password and username.name Private Sub btn_registrate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_registrate.Click'When the button called registrate (make new username) is clicked Dim username1 As Username'(I don't know if it must be dim blabla as NEW or without new with'my custom command)username1.name = Textbox1.Text 'Textbox for username username1.password = Textbox2.Text 'Textbox for password

Finally, in vb6 did not need the database linked to software to generate reports because it filled from a listview as the connection to the database do it for DAO ("C: ProSoft Billiard Data.mdb"). Now the question is as I can if I have to file a report so the connection in my software? is a bit urgent as I have to give and software and I need to do the reports.

View 3 Repliesi seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:
