I've written a Windows application which reads the title of a Window (which is in Greek)
and adds it in an Array List. However, when I MessageBox.Show(thatString) it appears as '?????'.
I am using this vb code, to save items from an array to a text document. But when I save to file, I get loads of speech marks around text
1. How can I remove the speech marks placed around text in file
FileOpen(1, CurDir() & "Back-" & DateTime.Now.ToString("D") & ".txt", OpenMode.output)
For First = 0 To 8

I have an application with a main form, on loading the main form asks the user to select a file to work with. I have now been asked to add a splashscreen to the project so did the following:
* Right clicked in solution explorer and added the splashscreen
* Went into project properties and added the splashscreen to the dropdown for splashscreen and then clicked "View Application Events"
Within here I have added the following
Protected Overrides Function oninitialize(ByVal commandlineargs As System.Collections.ReadOnlyCollection(Of String)) As Boolean
Me.MinimumSplashScreenDisplayTime = 5000
Return MyBase.OnInitiallize(commandlineargs)
End Function
Now when I run the application the splash screen shows but within, a second the openfiledialog has appeared and hides the splash screen.

View 4 RepliesI have a datagridview which is populated with information from a database. I would like it so that when I click on one of the items in the table, the information appears in the text box, or other suitable tool.
The VB output is an EPG (electronic program guide), that has a list of programs and the channels/time etc. So when you click on the program such as 'The News,' the data from the database such as 'Description' will appear in the textbox.

I have a window form with a label. On the form I have a dataset, bindingsoure, and tableadaptor (all created by the IDE in response to binding the text property of the label) To fill the datatable, the IDE created this: Me.ClientsTableAdapter.Fill(Me.MyDataSet.Clients) Works fine. The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

View 4 RepliesI'm inserting data into excel sheets and after i fill each sheet I want to sum a column so select the data and add a formula to a cell. However when the sheet is opened the cell contains the formula as text instead of the sumation value. I tired several ways but here are a few different meathods that both end up with the same undesired result.
Code:
'Meathod 1
oSheet.Range("H2:H" & (dtEntries.Rows.Count + 2).ToString).Select()
oSheet.Range("H" & (dtEntries.Rows.Count + 2).ToString).FormulaR1C1= "=SUM(R[-" & (dtEntries.Rows.Count).ToString & "]C:R[-1]C)"

I want to access each entered element in an textbox as an index in ArrayList. But, the problem is that whenever I enter value in the textbox, it stores all the values in single arraylist index.
View 1 RepliesSo, I have a textbox with the following text.
Code:
TITLE"Hello there"
blah blah blah etc...
I want my program to find the TITLE text, and then put the text in the double quotations in a variable.
How do you call the text that appears when holding cursor on a control as an explanation and how to implement it??? It has to be easy but I don't know how to do it For example Microsoft application functions all have it?

View 8 RepliesI'm writing a tabbed web browser for someone who is learning VB.NET, and I have got to the point where I can add/remove browser controls into tab pages, controlled by one set of buttons on the main form, but I can't handle events from the WebBrowser objects.I have tried this but it says that 'DocumentTitleChanged' isnt an event of 'Control'...
Dim browser As New ArrayList
browser.Add(New WebBrowser)
browser(0).parent = TabControl1.SelectedTab
browser(0).dock = DockStyle.Fill
AddHandler browser(0).DocumentTitleChanged, TitleChangedHandler()
I want to update the tab title with the web page title when it changes. I started using a timer to update the tabs but there must be a way to add an event handler here.
I am new to VB.net and I am trying to work out an exercise from a book I am reading on VB. Basically I am storing some book information in a hashtable using a class called Book to store the book information. I am trying to work out my Search and Display All procedures. My Search will work for the first value in my arraylist but not for any other values. I even added the ISBN to my book class to try and use this as a search point. The ISBN is used to pull the item from the hashtable as well.
In the main code I am having problems with the ButtonSearch and ButtonAll.

What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

I want to change ListBox1 with ArrayList. But I couldn't find how to use adding a string to ArrayList in tread.
I have an arraylist (arrFirstArry) which I use to populate another arraylist (arrNoDuplicates) preventing any duplicates from being added. This works fine. What I would also like my code to do is prevent adding any partial values which may exist from being added. i.e. my array is like this

What I need to do is read an ArrayList in My.Settings and add another ArrayList to it. The first think I'm trying to do is load My.Settings.Records into myArrayList. I'm not quite sure on the proper way to do this. I've tried things such as Dim myArrayList As ArrayList = My.Settings.Records, I'm not sure if I need New and I'm not sure if I need .Clone or .CopyTo.
Then I have another ArrayList myArrayList2. To get this into myArrayList I've done: [Code] Then to save it back to My.Settings I've done. My.Settings.Records = myArrayList. The problem is I keep on getting Object reference not set to an instance of an object error on the AddRange line. My.Settings.Records is definitely an ArrayList and it will sometimes = Nothing. The objects will only ever be strings.
I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
I previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?
I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:
Code:
Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1
[Code].....
If I need to load several text files into different arraylists, especially if the textfiles have a lot of lines, this process is very slow. Too slow for my current app to work smoothly, actually.
So, is there any faster ways to load a text file into an arraylist? Or if there isn't, is there some quick way to easily access and change data that is on a particular line in a textbox, so that I don't have to load the text file into an arraylist?
