The code I use:
Dim enc As New System.Text.UTF8Encoding()
TextBox.Text = enc.GetString(datas)
datas's type is Object, and its value comes from a .dll file that contains some data, such as "The web page address is www......"

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI have the code as below:
Dim xdTest As XDocument = XDocument.Load(GetXMLPath())
Dim objResult = From xe In xdTest.Elements("Some Element") _
Where xe.Element("strName").Value = strInput _
Select xe.Element("intValue").Value
objResult.
I cannot access any extension methods for objResult, like .ToList() or .First(). The file imports System.Linq and the project is targeted to .NET 3.5. How do I get the extension methods back?
I have a VB.NET application which runs perfectly with local host. But when I upload it to my server the session objects throw null reference exception.
Sessions is not working in a single page. If I use session on any other page it is working perfectly.
I have enabled session in that page using the EnableSessionState property. Also in web.config I enabled the use of session variables.
I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I have a form used to display records read from a dB. The record fields are displayed in textboxes to allow editing. When the form loads, it reads all records from the table and loads the first record to the form - very straighforward. I set the Textbox.Readonly = True after loading the data. I have an "Edit" button that sets the value back to false so that editing can occur.
All fields display correctly apart from the first field textbox where there appears to be no text displayed. If I press the "Edit" button and set the cursor into the textbox and use the arrow key to move left, the text is there. In other words, the text is loaded to the textbox but somehow it is hidden. Now if I move to the next record the field information displays correctly. The problem only occurs when the form is first loaded and the first record is displayed.
Now for the strange part. If I delete that (first) textbox from the form and then re-create it, the weird behavior moves to the next textbox control and the first textbox behaves correctly. I have checked all the properties for the textboxes and made sure they are all the same. I have had this problem before and found the only way to overcome it was to regenerate the entire form again. Does anyone have any clues on what is going astray?
I am trying to add a little functionality to my textboxes by making a label show when the values of the textbox are greater than a certain amount. The method is working, but only works on certain values (between >8 and 10) and I can't figure out why it won't work on values greater than 10.
Private Sub Submit1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Submit1.Click
Dim sum As Double
Try
If hrs1.Text <> "" Then
[Code] .....
I've also set the visibility of the labels to false in the onload event of the form.
Ok I am trying to make it so that if words are found within the 'Textbox1.text' they will be delete or remove or completely not allowed to even be entered into the text box. I have found a code on these forums from a previous post which has worked for me

i was wondering if there are other ways of showing data coming from the database.currently [ as per in my previous thread] i am using a [bind] datagridview.e.gthe table has
id, name, quantity
im thinking that listbox could be one, but it just shows 1 [e.g name].

I loaded up a checkedListBox with items form a .txt file. The .txt file has itemName, ItemPrice. Every item that gets checked shows up in a listBox on another form. The problem that I am having though is that I need to accumulate the itemPrices of the selected items to show up in a textBox, but the only price that shows up is the price of the item in the checkedListBox that has the focus. I'll add the code to this:
Public Class Form3

View 7 RepliesUsing vb.net 2008.I have used the "Using" keyword before in C# with objects that implement iDisposable.Can you use that keyword in vb.net also? What are the advantages of the "Using" keyword other than showing the coder when the object goes out of scope.I am under the impression that the "Dispose()" function is called at the IL level when you use "Using" instead of, for examplel, calling the Dispose() in the .net code.
View 1 RepliesI have looked around quite a bit, and nothing seems to answer my question in particular. I have DataGridView in which I add rows and columns dependent on a certain record count of geospatial data that is held in ArcGIS. The data is then passed through to the gridview for editing. So I do not use any databinding methods, rather it is a very manual process. I store data into a two-dimensional arrays, which indexes are based off of those certain data record counts. After the loops are complete, the data should be stored in each cell dependent on index. The very last row that was populated is populated perfectly, yet the other 72 (or so) rows are blank. Here is the code as follows:
