Is it possible to create a windows application in VB to take form input of a text box and put that to a sharepoint server as new list item?I want an exe that when ran, opens to a form with a text box or two and a submit button, that creates a new list item on a sharepoint list.I am using VS 2005 , code in VB. All my google searches come up with stuff that seems to run on the sharepoint server itself, not a program i hand out to people to run from the desktops.I've tried so many permiations of what i found through google searchs and my brain just hurts atm. I'm new to VB + VS, my background is in VBA on Excel, and i have an solution that works in vba, but causes headaches due to macro security etc.
View 1 RepliesI'm creating an editable ListBox control, where the user can double-click an item to edit it. When double-clicked, I simply overlay a TextBox over the item, so the user can change the text and then commit it by pressing Enter or leaving the TextBox. The 'commit' is simply this:[code]where 'editingIndex' is the index of the item being edited, and 'textBox' is the TextBox object.If the ListBox contains strings, this works just fine. The item being edited is replaced by the textbox Text string.However, if the ListBox contains some other object (let's say a custom class), this is a problem! It still "works", in that it still sets the text of the item, but the item is no longer an instance of that custom class! It is now a String, and all other information about the item is lost. So, I really want to let the user be able to change the text representation of ANY object, without replacing the object with a string. Obviously, I cannot know how the object displays its text (well, by the ToString function of course, but I cannot know what the ToString function returns).Now, I am having a few ideas how to approach this, but none really work the way I want. I am pretty sure that I'm going to have to provide some kind of event that the user has to handle. I'm thinking something like this:
- When the item edit is committed, an event is raised
- This event contains the Item being edited (as an object, the user has to cast it himself), and the new text of the item.-
- The user handles this event, and assigns the new text to the correct property.
For the Person class, this could look something like this.My ListBox should raise this event, and assign the new item like this.[code]I think this should work (although I haven't tested it), but there's one problem with this approach:When the items are just strings, the user still needs to implement this event handler, while he shouldn't have to (I can simply assign the new text string to the item). So, if the user is simply using strings, he still needs to do this for every instance of my listbox:[code]So what I'm really looking for is a way so that I can implement the default behavior (for String items), and still allow the user to override this behavior if he is not using strings.I may be overlookihe obvious solution here, but I can't figure it out... Overriding is done when you inherit a class, but the user isn't going to inherit my custom listbox (well he CAN, but he shouldn't have to). He is just going to handle the event. And if he doesn't handle the event, my listbox uses the default implementation.
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.

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I tried to do it as in vb6 using while not eof(but here i don't know what to write cause my file isn't opened in a certain channel).

View 5 RepliesI have a List myList of MyObjects. Is it possible to check if myList contains a particular myObject based on a property of myObject in VB.NET? In C#, you'd something similar to this right:
myList.Exists(myObject => myObject.property1 == 3)
I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1
