I have created a User Defined Control that contains Add, Save, Edit, Search, Delete & Close Buttons. I added this User Defined Control in a New Form & How can I call Add, Save, EditSearch, Delete & Close Buttons of User Defined Controls from the New Form. What is the Code for calling a button of User Defined Controls from its Parent form?

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
View 4 RepliesI have a couple of controls that are set to runat="server", but are showing up as "not declared" in the vb code behind. They are not being setup in the designer.vb file at all, even if the design.vb is re-created.
The only thing that I can think might be causing this is that the controls are inside of a custom control. The code looks something like this (it has been modified because of NDA):
<abc:MyCustomControl>
<additionalItems>
<asp:CheckBox id="coolCheckboxOfPower" runat="server" Text="Triple Rainbow!">
[Code]....
So using the example above, if I try to use coolCheckboxOfPower in my vb page, it says it is not declared.
It has been suggested to me that asp controls cannot be nested. Is this true, and if so, how do I get around that?
There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

example of a user-defined exception in VB.Net. I already have two examples that I was able to find online, but other than that, I cannot think of any more. I need to find at least 5 to put in my notes, and then submit to my teacher.The two I have so far are: invalid login information (such as improper username or password), and expired credit card information on an online store.
View 3 RepliesI'm a new user of VB.Net. I do have doubt on accessing a user defined Function or Sub. In some place of program, I do see the term "Call" when using the Function/Sub. In some other place without "Call". But both works perfectly. May I know the difference between the two.

I am a less-than-intermediate programmer who has done most of his work in VB6, and now trying to wrap my mind around the new concepts of the NET languages.In VB 2010, I have a Structure called "Direction", with one data member -- an integer named "Value". It's supposed to represent a value of degrees from 0 to 359.

Is there a way to create a user-defined ImageList? I would like the user to be able to assign images to ImageList that would be stored for use in future sessions.
View 3 RepliesWell I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

Im using a simple access database with only 2 tables and I creadted a form with a datagrid to show all data inside the tables, and now i want to create search buttons for each field of the table . like, "seach by Name", Seach by date" etc... i tried to use the simple code
Code:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim cod As String
cod = InputBox("Type the Id to search: ", "Search By ID")
If cod <> " " Then
[code]....
My biggest problem now is that this code works very well to search by id (which is my table primary key), but now i want to search by other fields and this code only allows to search by primary key! Is there any way to use something similar to this code to search by other fields?

I have a database of 7 items that I want the user to be able to choose the order in which each is listed for use further along in programming. I'm thinking of using combboxes bound to the database. I found out that each combobox will have to have its own dataset otherwise they will all show whatever the current one that has focus changes to. Is there an easier way to be able to do this or is having 7 datasets bound to the comboboxes the best way? For this purpose I don't need all the contents listed in a DGV, only need the component name for now if this helps. Database programming is new to me and I'm a hobbyist programmer from VB6 days making the transition.

I have a structure like this:
Code:
Public Structure Interval
Public temp As Double
[Code].....
'I want to be able to add to the array like an ArrayList though... 'after assigning values, like this:
interval(0).add
The main function receives data, uses additional functions to calculates the result and gives it back. But at one point, the function needs data from the SQL Server. I wrote a second UDF, made it visible and deployed it to the SQL Server. I see now two functions under > programmability > functions > scalar value functions:
1. The main function (IsCalcDay) and
2. The function with the data access (IsHoliday)
If I call directly the second function from VST in the debug mode, it works fine, bur if I call it via the main function, the code stops if the connection will be opened. The error is "Data access in this context is not permitted. The context is a function or method that is not marked with DataAccessKind.Read SystemDataAccessKind.Read or a callback to retrieve data from the FillRow method of a table-valued function or a UDT validation method." (translatet from German, probably slightly differnt in English)
VST (2010 prof) and the SQL Server (2008 R2) are running in my virtual W7 maschine.
Here is the code of the second function:
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes

Why can I open the connection if I call the function directly, but it fails if the function is called from another function?
Maybe I have missed something obvious. Currently I am using the feedback interrupt to change the cursor to one of the Windows supplied cursors
Instead of using the pre-packaged cursors, is it possible to use my own custom-cursor (icon), and if so - are there any rules re size etc., or can I use something like a png/jpg etc.. ?
I would like to make a "deep copy" of a class object that I have defined. See Visual Basic 2005 Code below
Dim MyStuff1 as new MyClass
Dim MyStuff2 as new MyClass
mystuff1.getbyID(anID)
mystuff2 = mystuff1
Unfortunately the statement "mystuff2 = mystuff1" makes a "shallow copy" of mystuff1. Therefore, if mystuff1 is redefined then so is mystuff2. What do I have to do in MyClass to implement a deep copy method such that operations on mystuff1 and mystuff2 are independent?I would prefer something like
mystuff1.deepcopy(mystuff2)
or
mystuff2 = mystuff1.deepcopy()
I'm writing a control that needs to check a property of the form it's placed in.Is there a way to do that?

I knew that the VB.NET has an error handling with Try..Catch statement. As I know, if there is any runtime error happen in the Try routine, it will only throw the error in the Catch. But what if there is no runtime error and I need to throw an error when I found the value of the calculation reported is invalid? Like for VB6, we can write the 'On Error Goto ErrHandler', so in VB.NET, how should we define similar method? For example, there is a simple mathematical calculation where the division of two numbers will never > 5. So if I found the result of the division is greater than 5, I want to throw an error to say the result is invalid.

rate 2 is 7% added to cost price= 10.70
rate 3 is 10% added to cost price.= 11
everything is fine till now, I am very able to do this... Now my problem sometimes the user may change the rates whatever he wants as eg. in this case rate1 maybe 10.80
