I am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code
Dim randomvalue As New Random
Dim randomhold As Integer
Dim newcode As Long
For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)
newcode = randomhold & DateTime.Now.Minute & DateTime.Now.Year
Label3.Text = newcode
Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.

I already made a code on vb.net to generate random numbers with letters using HEXA + date time. Now, all i want to know is how to set it to single use? Once they got it, they can no longer use it back. They have to request for new one..

I created a custom datagridview. In the constructor of that datagridview, I set
Me.AutoGenerateColumns = False
and then, declared and added 4 DatagridViewImageColumns and 140
DatagridViewTextBoxColumns by the code
...
Dim dvgCol as New DataGridViewImageColumn
[code]....
But when I add an instance of that datagridview onto a form, in the form.design.vb there are many code defines for each columns and then sometimes adds additional code to create those columns again. Sometime when I delete the datagridview control in the form,that code is not deleted.

I am trying to use a script mananger to use page methods to communicate between the server and client side of my page. I have added this code to the html
<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods="True">
When I add this, here is what is inserted into the designer page.
Protected WithEvents ScriptManager1 As Global.System.Web.UI.ScriptManager
But when this is automatically added, i get this error.
Error 52 Type 'System.Web.UI.ScriptManager' is not defined. C:UsersBillDesktopiPlan-7-layerlistingsummarytreeMain.aspx.designer.vb 32 44 iPlan
I added a reference in my project to system.web.services - but still can not seem to get around this error.

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.

I frequently use TextBoxes that expect date values. I do a tedious job every time to handle the Validating event. The Validation event ensures that the value is a valid date value according to the current thread's Calendar, and if so, formats the date to "dd-MM-yyyy".
I want a TextBox (e.g. DateTextBox) that automatically runs validation and formats its Text property. All I have to do is dropping it to the form.
I know I should use inheritance; but I do not know where to put the auto-validation code; and I do not know how to save the inherited class as a control in the ToolBox.

I have a VB 2008 app that creates controls at runtime. I can read these controls EG: textbox or dropdown by the following line.
<code>
TXT_value = CType(Main.Controls.Find(TXT_item, True)(0), TextBox).Text()
</code>
I can see the value but sometimes.. Sometimes I get a indexoutof range exception.

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

I am using ADO.NET Datasets in my VB Applications. I have a typed dataset with one Parent table and many child tables. I want to generate Identity Key when I insert data into Parent Table and then update the data in all child tables with the Same key (As Foregin key).At last, I want to update the dataset in Database(SQL Server08).Well, the above thing can be possible by first inserting Parent Table in Database directly, get the Identity column and than use to for Child tables.

I have a MaskedTextBox set to validate Zip Codes.
I set up my code to allow the user to enter either 5 numbers since most people like me don't know the last four of their zip codes.
The plan here is to allow the user to either enter 5 numbers or 9 numbers. The numbers cannot be less then 5 or more then 9.
If the user does not enter the numbers they cannot leave the field.
This is just a practice project.
This is the code I have written.
I have chaged this code multiple times for about an hour and cannot figure out what I am doing wwrong.
take a look:
Private Sub masTxtCusZipCodeField_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles masTxtCusZipCodeField.Leave
If masTxtCusZipCodeField.Text.Length = 4 Or masTxtCusZipCodeField.Text.Length = 8 Then

I know that when I add things to the designer in Visual Studio, it has to be generating code for them somewhere. Where do I find the code that Visual Studio creates when I add controls, change properties, etc in the designer?

but it's something I'm pretty consistently needing for the sake of my own sanity, so:If you add a Settings file to any project in Visual Studio, VS provides a GUI making it quick/easy to add a new Setting entry and assign it a Type; at that point the actual code-behind is automagically created with a variable and a property exposing that variable.Can we build our own designers to generate code this way, with a GUI allowing for those quick/easy variable/property assignments?

I'm trying to make alterations to an existing project, and I've found a project in the solution which is full of generated classes.Problem is, nobody here can tell me what generated them, so I'm pretty much left with pasting one of the classes in here and hoping someone will be able to tell me where they came from.
The solution I'm working on uses Expression Blend 3 and Visual Studio 2008. Dunno if that's relevant, but I'm trying to give as much information as I can think of... As well as this class, which appears in its own file, there's an "SPResults" file, which contains about 5000 lines of accessor classes of this type. Not quite sure why EndCustomer is in its own file...
From what I can see for myself, there's a stored procedure in one of the databases this program links to, and that SP's name is "GetEndCustomers". Something has then created a class called "EndCustomers" to represent the return type of this procedure.
The first part is a function from a class named Database, which returns a collection of the objects in question.
<FunctionAttribute(Name:="dbo.GetEndCustomers")> _
Public Function GetEndCustomers(<Parameter(Name:="Dummy", DbType:="VarChar(1)")> ByVal Dummy As String) As ISingleResult(Of Data.EndCustomer)
Dim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod, MethodInfo), Dummy)
[Code]...
So, yeah, can anyone tell me what has been used to generate this class? It could be something in Visual Studio, Expression Blend, SQL Server Management Studio, or some obscure bit of software I haven't even noticed is on the PC. Any clues, anyone?

This javascript generates a lot of text, but how I can I let my program get this text? BTW if I select the text in Firefox and right-click view source code then I see the source of the text, but not when I just view source code of the whole page.[code]....
