Get All My Textboxes In Tabcontrol Tabpage1 To Be Cleared Of Text Thru The For Each Loop
May 11, 2011
Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

I have 2 questions.
1- Let's I have a form with a TabControle and 2 tabpages, is it possible to set the tabpages so that if i go from tabpage1 to tabpage2 that all data on tabpage1 gets reseted. The same thing if I go from tabpage2 to tabpage1 that tabpage2 is reseted. Also if I press on tabpage1 or 2 that the form changes to a certain height.
2- On the same form I created a button to open a new form. This new form is a notepad look a like. What I want is that the moment I open the second form that al the input from form one is showed on form 2. So that I can save it or print it.

i have this to open a file:
Dim FILE_NAME As String = "C:Documents and SettingsOwnerDesktop esting.html"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
RichTextBox1.Text = objReader.ReadToEnd
objReader.Close()
what line of code am i missing to add the file name without the path in the tabcontrol's tabpage1, so instead of saying tabpage1 it would have my filename that i opened..
so much work to do and so many choices to choose from...

I am working on completing the Clear event for Button Clear Sub routine. I have been able to clear the textboxes with the code I already have. However, in playing with the application, I noticed that the memory remains stored somewhere in the program. How to both clear the textboxes, and clear the memory?
Code
Private Sub btnReset_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReset.Click
txtTestScore.Text = ("")
lblNumberOfScores.Text = ("")
lblAverageScore.Text = ("")
lblBestScore.Text = ("")
txtTestScore.Focus()
End Sub

Is this possible in ASP.NET? If so, how can this be done????

I have a drop down menu, and based on which item is selected, I call a web service and then dynamically create some text boxes.The first time I drop down the menu and select an item, it works perfectly, and the text boxes are created and populated dynamically. However, the next time I drop down the menu (after the first postback), and select something different..fter the second postback, the original values remain in the textboxes.

i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound

Using Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text

I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I have a FormView bound to a SqlDataSource on my page. One of the controls on the FormView is a DropDownList, which gets populated on Page_Load (it's being populated with a list of file names from a specific folder).
Everything goes well when the page first loads. I am able to view the list of files, select one and, upon hitting the "save" button, store the correct filename in the database. However, when the page refreshes after the post back - the DropDownList is empty.
