Tabcontrol Populated With Pages Tab1 Tab2 Tab3?
Feb 22, 2011
I have a Tabcontrol populated with pages tab1 tab2 tab3.What i want to do is if a user begins a function in lets say tab2, it wont let them select another tab until either the function is complete or function is cancelled.so to complete the function designed on tab2, i have but_edit to begin the editing (this is where the tab selection would be disabled), and i have a button set as But_Save, this would save changes let them select a different tab again.
So far i've managed to control this with tab1.enabled = true/false etc, but this doesnt produce the result i want, i want them locked to the tab until But_Save or But_Cancel is pressed.

I have a usercontrol which has a number of labels on it. The usercontrol acts a bit like a listbox but I can control the background and foreground color of the labels it contains - nothing fancy use it for logging a process - a bit like a scrolling console window.I have a form with 3 of these controls, Progress, Errors, and a debug logger. Works fine when placed on a form until I add a tab control with three paces and place each usercontrol on a tabpage. then random labels are not updated.

I have a project with a form in which I have a tabcontrol with several tab pages. In each tabpage I have a datagridview and some textboxes and some comboboxes. I managed to refresh one datagridview but it stopped working. - I don't know why. Here's what I did:
Public Sub RefreshGRD()
Me.Adapter.Fill(Me.DataSet,"table")
End SUb
And I called this fnction before closing the connection for each button that adds or deletes or updates. Before calling it I cleared the dataset.

My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?

I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer
Pages = New Integer() {1, 3}
PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.

I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:

I have heard of setting server specs to have HTML pages parsed as PHP pages by changing the .htaccess or httpd.conf files. Is there a similar solution to have HTML pages parsed as ASPX pages?
A website I am working on does not want their PageRank to lower since their HTML pages are already indexed and used on other websites but wants to use some dynamic features of aspx pages (like include the navigation file so that changes to the nav will only have to be done in that one file).

I have several combo controls that need to be populated with a specific ID and name. I want the user to choose the name and have the ID in the background. Later when the data is exported from the database the specific ID's are exported and not the names.
I see that I can create the items in the combobox rather easily using their names. However, how can I associate the ID number for each of the items. Private Sub frmReceipts_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Add receipt types to combo box
cboReceipt.Items.Add("Monetary")
cboReceipt.Items.Add("Inkind")
cboReceipt.Items.Add("NSF")
End Sub
I thought it would be better to have a seperate table with the different receipt types and then somehow connect/link the contents of this new table to the combo box on this form. However, I am at a loss on how to do this.

I tried binding a DataGridView to a DataSet using the DataSource property but no data appeared in the DataGridView. I placed a DataGridView in an empty form, making no property changes except for the name. I did not create columns in the DataGridView. In the form's load event I placed the following code for loading a dataset named ds Executing in debug mode, I confirmed that there was data in that dataset. No column headings or data appeared in the DataGridView. What am I doing wrongly? There are 34 fields (columns) in the DataSet - maybe it exceeds the capacity of a DataGridView.

I am fairly inexperienced with using datatables in VB. My question is this: Can I access a particular column of a table by name if it is not defined elsewhere like when I populate a datatable using sqldataadapter.
[Code]...
Is this the way it can be done? I believe this is the case, but can't find any definitive examples online (probably not searching properly)

I'm having trouble using an arraylist with an object. [code] The arraylist Phrase gets populated with 4 objects (WordObject) filled with the word "Fox".The arraylist AnotherPhrase gets populated with strings "The", "Quick", "Brown", "Fox".Why does the Phrase Arraylist do that? Shouldn't there be 4 objects each with different words?

I have a project that currently uses an XML config file to create some groups. Based on these groups, you can search a database for information. What I want to do is create a form for editing that file. I can get to the information via messagebox, but when putting it into a ComboBox, I can't get the list updated. I have tried the text property which only populates the initial selection, and the Items is a read-only property. Nothing else looks close to what I want to do.
My other thought is to populate a datatable with the information and then populate the combo box from the database. It seems like an extra step that I shouldn't need, but it may be the only option right now.
The reason it can't be hardcoded is that the XML config file is already being used by a program, and the file may be updated from two or three computers, meaning I need a central location for the file.

I'm trying to get a combobox to be automatically filled from a text file and have it editable by the user.
So far, when the program is running I can add new items and they appear in the text file and combobox but when I restart the program the combobox list is empty even though the text file has stuff in it.
Dim w As New IO.StreamWriter("z:url.list.txt")
Dim linecounter As Integer
For linecounter = 0 To ComboBox1.Items.Count - 1
