For my ToDo list I need lots of variables to store data in.Each item of the list has 3 strings in it: Activity, start time and end time.To make multiple tasks in my ToDo list I think it's the most usefull if I use this: 'For x = 0 To 1000', so on the launch it will make 1000 variables to store my data in.But for the 3 string for extra info I need something like this:
x.a
x.b
x.c
Where x is the integer, and a, b and c are the 3 strings. If I try to do this I will need to do 'Dim a, b, c as String', but that way it will not understand x.a x.b and x.c If I do 'Dim x.a, x.b, x.c as String' it gives me an error, because x.a is not a String...

I found a code example online that purports to count the number of pages in a PDF file. However, I'm getting the error 'ToArray is not a member of 'String' on the following line:

I'm running VS 2010 on a Framework 2.0 project, on a machine running Windows 7 and IIS 7. I found one article that talked about IIS configuration as the culprit for this error, but my settings seem to be consistent with what they recommended.
Got an issue with lstFriends.Items.Add part of this code, says that "Items isn't a member of String". What does that mean exactly and more importantly how do I fix it so this code will work. What I am trying to do is make it so the btnAdd will add a name to lstFriends if it's not there already and for the btnRemove will remove a selected name
How can I get the type (it's name as a string) of:
1) an unassigned member?
2) the current class (I mean the one in scope) when no instance is available and without using a shared method?
EDIT: Come to think of I, I'm starting to think 1) is impossible.
EDIT: 2) may in fact never occur as such. Actually I meant the parent class of a nested class when no instance of the parent class is available (but an unassigned variable is) and without using a shared method of the parent class
I have two windows form applications (vb.net 2008 Express) which are nearly identical, one built from template of the other. The following line works fine in the first:
Dim day = CType(DayOfWeek.Parse(GetType(DayOfWeek), strDay), DayOfWeek)But in the second app I get the error " 'Parse' is not a member of 'String' ".
I keep getting an error message in my code "text is not a member of string" on each line similiar to: TextBoxVerb1 = TextBoxVerb1.text.Trim and I can't figure it out. Here is the code:
Private Sub Buttonsubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Buttonsubmit.Click Dim str As String
Is it possible to find a particular string present in a string array?Example Dim myString as stringmyString = "abc" Dim myStringArray() As String = {"rg", "grg", "grg", "dgdg"} Is there any way to find myString is member of myStringArray, without writing any loop?
I have a small form that i open from several other forms with showdialog, as a little pop-up thing. Its used to sed SMS messages via an email to SMS service.Because it can be opened from several other "parent" forms i need to know which form opened it, and then i put some text in a notebox on the "parent" opening form.
Heres the code im using to open the form:
Private Sub Btn_SendSMS_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Btn_SendSMS.Click SMSForm.TBMobileNumber.Text = Me.MobileNumberBox.Text SMSForm.OpeningFormName = Me.Name
I have a label with name "Label15" and and a button "button1" on my form.
in my code :
Label15.text = "Button1" dim myitem = label15.text
[code].....
this code does not work...when I put it in a msg box to show the error : it appears as buton1.performclick()and if I write button1.performclick() manually ,then it does the operation.I want to trigger the perform click operation from a textbox.text. Main error is:Public member 'PerformClick' on type 'String' not found.
I'm having a bit of trouble figuring out this error and what it means. Here is the code that is throwing the error,
For Idx = 1 To cboCallType.Items.Count - 1 [b]' If cboCallType.Items(Idx).Selected = True Then ' If Item is Selected[/b] For I = 1 To cboCallType.Items.Count - 1 ' Set Index to look at the array
Public member 'Selected' on type 'String' not found. I'm assuming this error means you can't select a String in the combobox? I always thought you could, I'm just checking to see if one of the items were selected before moving on with the code, what other way is there to accomplish this and/or what does this error actually mean and how do I go about solving it?
I'm "cloning" objects in my code. For instance: objClone = objOriginal My question is: Does the assignment operator in VB.NET 1.1 do a member-by-member copy of the objOriginal to objClone or does objClone simply point as a reference to memory referenced by objOriginal?
I am currently making a server monitoring application that pings the server to check its uplink, so far it creates all the picture boxes and labels for each server, and then pings the server, although I have a picture that I want to change dependant on the result.
Below is the code I am currently using, the problem occurs with the objectname variable which allows dynamic coding, where i get a error, saying that "Public member 'image' on type 'String' not found".
Private Sub Ping() Dim i As Integer Dim objectName As System.Object For i = 1 To count - 1
i changed a class variable to shared so i can access it in all instances of the class, but it caused an error. what is causing this, and how can i fix it?
I have 2 tables Table A & Table B Table A has the table values that I want to be populated in a datagridview control.The challenge is that column 1 in table A contains an ID(foreign key) to a name field that is a located in table B. I need the datagrid to have the first column be a combobox that displays the names(from Table B) that are already in table A via the ID's, but reference the populating values from Table B. So that when you bring down the combobox you would be choosing from Table B data but populating table A with the ID and you would see a name there instead of an ID.[code] How do I populate my DS dataset with Table B? And how can I create a link to these two tables using a bound datagridview control?
I am using VB.NET and Visual Studio 2010 to write my program. The source of the control that I am using can be found here. First, I imported the Calendar.DayView.dll file into my toolbox to use as a control. Then I added the following code to my existing code:
Private Sub DayView1_NewAppointment(ByVal sender As System.Object, ByVal args As Calendar.NewAppointmentEventArgs) Dim appointment As New Calendar.Appointment() appointment.StartDate = args.StartDate appointment.EndDate = args.EndDate appointment.Title = args.Title appointments.Add(appointment) End Sub
I get this error 'Title' is not a member of 'Calendar.Appointment'. I have no access to the Calendar namespace or the Appointment class. I am able to view the properties of both in the Object Browser but I can't edit any of them.
I am making a WoW automatic trial account creator and so far i have it so that on this link:

it will fill out all of the information.

The only problem I am having is that when I try to make it automatically submit it isnt working because I can't find the id of the button. When I inspect it on the website it is a javascript button and I am not sure how to make it click. I tried
I've got an project that whenever an exception is throw will generate an error log. It was debugging fine so I decided to build a test version to let some co-workers try out. The build didn't work exactly right and I had to alter some reference properties to get it to build. Now I have the following error, "Reference to a non-shared member requires an object reference."The red highlighted text shows "reference to a non-shared member requires an object reference.
I have got this error No default member found for type 'VB$AnonymousDelegate_0(Of SqlDataReader,String,Object)'.
