IDE :: Cannot Find The Component - Creating A Two Dimension Array Of This Item?
Mar 14, 2012
I retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?
I'm using Streamwriter/Streamreader for the first time in this project and keep getting an "Argument out of Range Exception was unhandled" error.It says "length cannot be less than zero. Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value? [code]
I have an array called linedistancearray.I am now trying to find the smallest integer in that array and store it another variable called mindistance..The following is my initial idea: I sort the array and then pick the integer with index 0. Array.Sort(linedistancearray)However what I get is the first item being a 0 not the smallest integer value in the array I need. HOWEVER if I choose the index 1 it works.So what I was thinking was a way to remove all 0s in the array. I am not concerned about the order of the items at all all I am looking for is the smallest integer in the array.
I'm making a function that searchs an array of Customers and returns a Customer object by a given ID. I'm trying to do so with Lambda Expressions,and this is what I have so far:
Public Shared Function FindCustomer(ByVal ID As Integer) As cCustomer
Dim customer as New cCustomer = _ _ Array.Find(arrCustomers, Function(c as cCustomer) c.ID = ID) Return customer End Function
How do I use only one dimension of an array? What I have going on is: I have an array suit(1, 4) and rank(1, 13) to represent a deck of cards. What I want to do is take the value of the rank of the selected item in my listbox to be able to add it to the rank of other selected items in the listbox (essentially adding the players hand together). [code]...
I have an application in VBA that gives to my VB.Net dll one bi-dimensional variant. It is a an array, in which every component is a another array containing two positions.
I want to get this two-position array. When I am using VBA I can access directly the data from each position by doing:dataArray(index, 0) or dataArray(index, 1)And when I want to get the two-position array I can use:
Dim posArray as variant posArray = dataArray(index)
I need to add an additional dimesion to outputArrayOfBits() in the code below which I hope conveys my intention. I need to convert a one dimensional array of 1 to n boolean (bit) values into arrays that group them by 8's so the output can be consumed by someone needing these values to be in hex format (0000 1111) = 0F How do I change the declaration of 'outputArrayOfBits and the nested control loop to achieve that?
Dim inputArrayOfBits As New BitArray(32, True) ' I can't change this. 'Create array of bytes containing what will be sent out has hex numbers 0 - F 'outputArrayOfBits(0) = (1,1,1,1,1,1,1,1) 'Hex value FF
I need to manipulate data for 1000 boxes, each one of these boxes has 8 variables.How to declare an appropriate array? and how to load the array with the 8 variables for each box?
I am trying to create a multi dimension array that will search each row of the array and total up the number of 0's 1's, 2's, and 3's. I believe that I need to create some sort of looping structure that will search through each row of the array.I have created a listbox that will allow the user to pick which row of the array the program will search.This is what I have created so far, but I am only just learning and I am having trouble wrapping my head around how arrays work. So I'm not sure if I am on the right path or not.
Dim racescores(,) As Integer = {{0, 1, 0, 3, 2}, {1, 0, 2, 0, 0}, {0, 3, 0, 1, 0},
I'm trying to return changes to array data, including redimensioned arrays, from within a function call in code similar to: fault = MyFunction(Array1, Array2) Public Function MyFunction(ByVal inObj1 as UserStruture(), ByVal inObj2 and Integer(,)) as String Dim myResult as String = "Failed" Dim tmpStruct() as UserStructure = inObj1
[Code] .....
This works fine in updating the input array 'Array1', only when the redimensioning of tmpStruct is NOT performed. After redimensioning tmpStruct, the redimensioned array is passed back successfully into 'inObj1' within the function 'MyFunction', but is not passed out of the function call; i.e. fault = MyFunction(Array1, Array2) -
The dimension of array 'Array1' out of the function call remains as it was before the function call. However, the data change; i.e. tmpStruct(0).Nam = "New Name" is passed successfully out of the function call.
Why the Redim operation is not passed back out of such function calls. I would like to return changes to arrays 'Array1' and 'Array2', plus a result string from the function call if I can. Furthermore, I would also like to change the dimension of the array within the function call, if required, and return the complete redimensioned array back out of the function call.
I have the following array in my project that I'm trying to redim without losing the values.The problem with redim preserve is I can only redim the last dimension of the array. I want to redim the 2nd dimension without losing data. How do I get this to work?[code]
i have used in vba 3 dimensional jagged arrays where i had up to 10000 rows. i am now transferring this to vb.net and learnt that it would be better to work with lists. the dimensions are such as (30, 10000, 30). how would i structure this by using lists?
I have a grid 10x10, at present is in the form of a multi-dimensional array:
my_Array(10, 10) as char
[Code]...
Additionally this shape can be in any orientation and more than 1 as in the above example.Does anyone know a quick way to do this? e.g regex?Or alternatively achieving the same result by using a different structure rather than a multi-dimentional array?
I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.
I have a gridview in my asp.net website that and I use vb for the code behind. Each time a row is bound an even called the Gridview_RowDatabound event is fired. So what I am doing is looping through all the cells in that row: [Code]
Problem is I get an error saying redim can only change the rightmost dimension. It would suit my needs to change both dimensions here as my final result will be to total each column in the array. what other method can i use if arrays don't suit this task.
VS Express 2010 gives me a "Creating an instance of the COM component with CLSID {D70E31AD-2614-49F2-B0FC-ACA781D81F3E} from the IClassFactory failed due to the following error: 8007000e."

Here is the method call:

I am wondering if I can extend a component (e.g a button ) in vb the same way I can in java which enables you to modify the component for your specific requirement or create a new one from scratch.
I copied the following code from a book that helps to create a serviced component is a solution called SyncDemo in VS2005 with an application project called ClienteSyncDemo and with other class library project The code of the form ClienteSyncDemo is the following Public Class Ejecutar Private Sub btnEjecutar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEjecutar.Click
I have just downloaded and installed both MS Report Viewer Redistributable 2005&2008 but I could not find it in the .net framework component. I am using Visual Basic 2008 Express Edition, does it mean the express Edition does not support such component?
I am using msn api to read contacts out of msn Interop.messengerapi.dll
When I run the app on my machine everything works perfect. But when I run it on another machine, the following error appears: Creating an instance of the COM component with CLSID {B69003B3-C55E-4B48-836C-BC5946FC3B28} from the IClassFactory failed due to the following error: 8007000e.I have merged the interop messenger dll properly with imerge, so that cant be the problem.
Also a memory problem must be out of the question. I only use 300mb from the 4GB. There is also enough disk space available.
My Code: Private Sub getMSNContacts() Dim objMSN As New MessengerAPI.Messenger Dim msncontact As MessengerAPI.IMessengerContact Dim msncontacts As MessengerAPI.IMessengerContacts = objMSN.MyContacts For Each msncontact In msncontacts ListBox1.Items.Add(msncontact.SigninName) Next MsgBox("getMSNContacts") End Sub
So I have a custom control that when added to a form will create two child controls inside it. The custom control's designer handles the creation of these. The problem I am having is that when the designer generates code for these controls only the parent control is declared "WithEvents". So my que
