This is my first post. I have just started some serious .NET programming. Can anyone help me understand what is a good, industry standard in developing the VB.NET or ASP.NET applications? Should we use the Automatically generated code by the VStudio or we should be coding manually i.e. handling the datasets, populating the controls etc instead of using the automatic generated code using wizards.
View 12 RepliesIn the early generations of VB.NET visual studio, I used to see an automatically generated region named "Windows Form Designer generated code" that includes the code that generates the controls at the surface of a form. But what happened with VS 2008, I can't see that region any more ? Where are the lines of code that are automatically generated that create controls and set there properties ?????

My database's layout is as follows:
Identification (Parent table)
ID# (Primary Key, auto increase)
First Name
[Code]....
I am placing this three tables in three tabs by a tabcontrol. If I put two child tables in dataGridView in their tab, the insert(new record)/update to the tables works very well. When I put the child tables in details View, I can't get a new record updated. The problem with details view is that there is no AddressID and VehiclesID generated. In dataGridView, these IDs are automatically generated whenever a mouse enters into a cell in a row.
The primary key of the table is generated automatically using the Is Identity and I want to update based on the primary key. There is certainly something wrong with the following code, so I'd like someone to modify it for me.
Try
Dim qry As String
qry = "Update StudentDetails.Programmes set Programme=@Programme,Form=@Form,AcademicYear=@AcademicYear,Class=@Class where ID=ID"
cmd = New SqlCommand(qry, cn)
[code]....
Firstly I apologize as my question may seems repeated to you. But I am sure the details will not. I am writing a VBScript in VB.Net to automate some operation in SAP. The script is recorded from SAP. All I need to do is to put this script under a button click event on vb.net. I have done this far. But get stuck at one point. While doing the execution of the script, SAP displays a Message Box with two button labeled "Redetermine" & "Cancel" and I have to Click on "Redetermine" button to make the script run further.
The number of appearance of this message box is not fixed. Some times it appears twice and some times more than twice. My question is "How can I detect the Message Box from my VB.Net application and automatically click on the "Redetermine" button if the message box appears"?
I am currently working on a program, that you enter certain values/text in and it organises it into a word document automatically,
I found a code online, which has worked a treat, However I'm wondering what lines of code I would need to:
1. Add Bullets or Numbers
2. Add a new line of text (I can add a new paragraph but I don't want a huge space between the two lines)
3. I have around 20 check box's is there a quicker way to check which are selected then write the text in word or do I have to write alot of If Checkbox1.Checked = True then, etc)
I have difficulty in using the vb code dom. Basically, I want to compile this piece of code dynamically:

View 10 Repliesbut 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?
View 4 RepliesI 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

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'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)

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?

View 2 RepliesI have started with a small project in VB2008 Express which grew to a complex application. I have deployed the application recently discovering it is rather small, and the major issue is that code-generated controls (checkboxes, comboboxes, textboxes) are not displayed as during development. I have declared the code-generated controls in the declaration region, and there are about 250 controls. According to user selection some of the controls are added to a container panel. Now, I am concern that because I declare those as public (static?) variables, it uses much memory and causes the problem in the compiled application. Is that correct that static declared and code-generated controls uses much memory? How to avoid it ? I need the controls as public variables. Is it better to add all 250 controls on the form in designer mode, and use the property Visible (control.visible=True)?

I have a project with requirements to generate a single executable file with no dependencies that will automate the submission of data to a WCF service based on command line parameters passed to it. As a result, I cannot configure the WCF binding and quotas in an App.config file, so I am generating a BasicHttpBinding in code to use when dimensioning the WCF client object.
However, the WCF service accepts the binary data for a relatively small Excel spreadsheet that ends up being around 30kb, so the default configuration settings for the binding's ReaderQuotas are inadequate. My attempts to increase them in code to 1MB, however, have met with failure each time I make a call to the service.[code]...

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

For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)
newcode = randomhold & DateTime.Now.Minute & DateTime.Now.Year

Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.

Most of my project was imported from an older version of VB (now I'm using 2008). All of the forms had a "Windows Form Designer Generated Code" that I could expand at the top of the form's code. When I created a new form, that was not there, and I found out that in the solution explorer you can "view all files" and expand the form and look at MyForm.Designer and that has the same type of instantiation code. My question is, is there some way to update the old ones so they too do not have that "form designer generated code" at the top?

View 2 RepliesI've got a form with a TabControl. PictureBoxes (containing thumbnails) are added to each TabPage thru a loop. A click event Handler is added for each PictureBox. When a PictureBox is clicked, a new form is created thru code and a PictureBox is added to it that shows the pictures enlarged. What I need is to add another Handler to the PictureBox in the code-generated form so that I can rotate the pictures because some of them (photographs) were taken with the camera at 90 degree angles from vertical. I've tried to come up with a solution but I always run into the problem of the PictureBox on the code-generated form needing to be declared WithEvents before a Handler can be added.
Code for adding PictureBoxes to TabControl:
'Variable p declared public withevents at class level
p = New PictureBox
img = Image.FromFile(Path.GetFullPath(picfile))
