Sub RosterItem(ByVal sender As Object, ByVal item As agsXMPP.protocol.iq.roster.RosterItem)
If I look at all the attributes of item declared above, I can find the account the rosteritem was sent to under that parent tab.. but I can't do item.parent.parent.to.user to get to it. How can I get the parent item's parents' information?
I have 1 table which has columns which include "parent" which says who the parent is if there is a parent, and "name" which has the name of the item. so for example
[Code]...
or something to that affect. the reason being that the user can do the autocomplete by typing a letter or a few letters, it will go to the parent and then they can use the enter key to move down 6 or so down at a time( if possible) or arrow to move 1 at a time down.
Is this possible in DGV or should I go use something else? I have seen this used in a program before but I do not know how it was implemented.

View 1 RepliesI've made a project with a menu.This menu is placed in a form which i use as a MDI Parent, and all the other forms are opend in this parent form.Everything works ok.
When I open a menu item (eg form A), the form display's correctly.But when I minimize the procject to the taskbar, and maximize it again, Form A shifted position a bit lower.
I can't figure out what's going on.
I have a simple user control which wraps some logic around an AutoCompleteBox. This question could apply to any ItemsControl control like a dropdown or listbox though.
<UserControl>
<Grid Background="White">

I am looking for a way to extract information from a website.That is, by using VB to connect to a site, and retrieve the html code. I then parse it this way.To be more precise, the site is eBay,and I am looking to get certain item information from certain items.I read somewhere that somebody converted it to XML maybe? MSXML was used.

View 1 RepliesTwo questions:
1) I have a stored procedure that retrieves item information from a SQL Express database. Should I attempt to do the rounding the stored proc or client side in the app?
2) My rounding needs to be custom. I have a figure that goes down to the 4 place meaing x.0000 if the 3rd digit is 4 or more then I would round up to the nearest cent x.00 if it is 3 and below I would round down. I have looked at the math functions in vb.net and I dont see right out the gate how to accomplish this.
So my question is should rounding be done in SQL or client side and if it is client side do any of you have pointers on how to slice and dice this?
I'm trying to load up a comma delimited text file and have only the name of a person loaded into a listbox. Then when the user selects a person from the listbox have additional stats pertaining to that person show up in a label.
View 4 RepliesI am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:
Public Class Parent
Public Property Id As Integer
Public Property Name As String
[code]....
I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:
Dim firstParent = (From q In db.Parents Select q).First()
For Each child In firstParent.Children
'Do something
Next
The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...
EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.
i make a parent and children form and when i show children form and drag into parents form , when parents is little to show the children form , parents form enables the scrollbar and then show the chilren form better , how can i do something that avoid this status ( don't show scrollbar into parents form when the children form is bigger than it)?
View 1 RepliesI have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.
I know generally it is not the best solution for a child to handle an event of parent. Take this for example; Mainform loads UserControlOne, UserControlOne handles all UserControlOne needs to. How ever we need a MenuStrip/ToolStrip. MainForm does not need to know much about what UserControlOne is doing. Other then receive some information on a statusbar. Right now events are controlling this.
The menustrip/toolstrip need to be able to speak to UserControlOne, for example when buttons are clicked on the strips. Would you; Allow the child to add a handler to capture the parents event? Move the MenuStrip/ToolStrip/StatusStrip all to UserControlOne so we can ignore all this event hassle? My Major concern with this is now we have taken all the head ache away from MainForm and crushed it into UserControlOne. Any suggestions?
I like to build objects that contain properties and also functions / subs to do work. I dont have a lot of other programmers around me to answer this question so I thought id ask. If my goal is to make a function or even sub part of a class blue print is it better to do it by making a seperate class for the function, and then construct a new copy of the classFunction as a property of the parent class or is it better to simply put the function in the parent class.

I have a Dialog which I'm calling via Loading.Show()Can I lock the position and location to the parent form? In such a way so if the parent is minimised or moved, the child will stay centred to the parent?
I was using ShowDialog() but this obviously stops the parent from being accessible. This is being used to display a progress gif. (Child is 50% opacity)
I have a big problem regarding MdiChild. My problem is that I have 3 forms loaded;
Form1=Mainform / mdiParent
Form2= Display the Datagrids
Form3= This is where I let the user input the necessary fields like Lastname, Firstname,Age,etc...
My problem goes like this, Form3 is the child of Form2, Form2 is the child of Form1 and I call them one by one like this:
//form1
Form2.MdiParent = this;
Form2.Show();
[code]....
I want in the Form3 to save data and refresh on my datagrid on Form2 so that every data that I encoded in Form3 will reflect in Form2. I let the Form3 close everytime there is data entered but my problem is that the data that entered doesn't reflect in my datagrid.
I have a main form and I've created another small form.In the main form I show the small form when they click a button, like this:

Handles AddButton.Click

then the LicenseNewForm appears. The problem the I stumble upon is how I get the information from the license form to the main form when they click a button in the license form or close the license form. The information is more then just a simple input, so I can't use a InputBox call because the license form has 3 comboboxes and a textbox to get the input from the user and then I need to send that input to the main form.

View 9 RepliesI have an aspx page which houses an iframe. When a button is clicked, a WCF is called to produce a PDF which is read into a byte array. I was storing the byte array in a Globals.vb file like this:
Public Shared PDF_Data as Byte()
The global was loaded from the parent aspx page like this:
PDF_Data = MyWCF.Create_PDF_File(SomeVariable)
After that, the iFrame's src was set to a blank aspx page, which had the following code in the page_load event:
'Write the PDF binary data to the screen (viewer)
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/pdf"
Response.BinaryWrite(Globals.PDF_Data.ToArray)
However, realizing that this application will have several users who will get different PDF documents, I have learned that this is not the way to go. My shared variable would be accessible to all users, a big no-no.However, I am stumped as to how I'm going to store the byte array and make it available to a child aspx page from it's parent.

How can i remove all the TagReferences which contain the ReferenceID in one line?
I have an application and Spy++ reports that the parent window has many controls that are hidden. When I do a mouse click on the application's window, a number appears and I suppose it's the hidden controls that change their text/picture.So, is there a way to iterate the parents hidden controls names, get their handles and then activate them one by one (with sendmessage/postmessage wm_buttonclick) to see what changes?Right now I get the windows handle with FindWindow and the window's process id.

With this code provided by a contributor from this forum ive been able to sort listbox items acording to date from older date to newer date, heres the
Dim dates() As Date = Array.ConvertAll(ListBox2.Items.Cast(Of String).ToArray, Function(s) Date.ParseExact(s, "dd-MM-yyyy", Nothing))
Array.Sort(dates)
[Code]....
How could i use that code to work these out based on only partial checking, what i mean with this is, to sort only by the first date or, to sort by the second date, i rather have it sorted by the first date before the arrow because that is the alarm, the after the arrow date is just the event date information.
This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata
Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this

frmmain = new mainform
In frmMain I am doing this

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
