Searching Textboxes Inside Tabs?
May 27, 2009
I've got the following issue: I want to make my program change the Backcolor property of all textboxes inside a TabControl. The problem is that one of the Tabs has got another TabControl in it, and I need to change those too.I'd like to to it all at once, but I'm getting an error using this code.
vb.net
For Each SpeechTextBox As TextBox In TabControl.Controls
SpeechTextBox.BackColor = ColorFondoTablasUSE[code].....
The error I get says this:
System.InvalidCastException was unhandled
Message="Unable to cast object of type 'System.Windows.Forms.TabPage' to type 'System.Windows.Forms.TextBox'."
I read somewhere in the forum how to make this work, but I can't find it.

How would I use FileStream.Read() to search for a string inside a file and then return the string's offset? (basically like a Hex editor)

I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4
Allen Iverson,28,7,4
Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
textboxoutput.text = PlayerName & " averaged " & PlayerPoints & " points, " & PlayerAssist &" assist, and " PlayerRebounds " &" rebounds"
So basically, I want it to where the user can enter a basketball players name and display the values for that name.

[URL] I'm trying to do an exercise on that website but it doesn't show the answers to the exercises..
I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part:
Ignore the second if I was desperate xD
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code].....
And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?

This is my first time using WPF. It has been a bit of a nightmare, but I've done enough of the project that I now don't want to start all over again with a forms application.
My problem is this: I have 50 textboxes inside an expander, which in turn is inside a stackpanel. I need to store the value of each textbox in an array. In forms I would probably do it something like this (I am using vb.net by the way):
Dim i As Integer
Dim values() as string
For i = 0 To 49
values(i) = form1.Controls("TextBox" & i).text
Next i
(Assuming my textboxes were named Textbox1, Textbox2, Textbox3 etc.)
How can I do this in WPF? I've tried using Trees (I think they're called?) but have failed every time and now given up.
Oh, I also forgot to mention that there are also other controls in the expander (labels that are paired with the textboxes).

Can you add values inside textboxes that are located in tables in Visual Basic 2008?
I put a TableLayoutPanel on a form and inside the Table I put textboxes. Outside the table there is a button. The whole point of the program is so that the user inputs numerical values inside the textboxes and then hits the button and the answer comes out in another textbox. But its not working. It worked when I didn't put my textboxes inside the TableLayoutPanel.[code]...

[Code] Somewhere my system haves a function that returns a DataSet with the books of a certain subject and all the Authors that wrote such books. I need to show the book's attributes in some textboxes inside a Form. I use a BindingSource to display the ISBN, Name and Subject of the books in a textbox, yet I don't know how to display the author name of the book I am currently viewing in a TextBox, taking into account I already fetched the Author into the DataSet.
Its pretty much the Child/Parent display problem somewhere discussed in the codebank, but kinda backwards, the thing is that I;m navigating through the CHILD records here, not the parent, yet i have all the data needed in my Dataset.

I was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?

My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.

I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?

On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If

I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

' Instantiate objects of the various database interaction classes.

im new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.

i m trying to load the tabs dynamically.(Using AjaxToolKit). Firstly, when i hit button1 on pageload, it loads tab1() (works good) and when i hit button2, itloads up tab2() All these tabs are ascx pages. In tab1 i m loading WebUserControl.ascx. it works okay.
Issues:
1) When you runthe code, first click on button2, it doesn't load tab2 dynamicaly but it does when u hit button1 for the first time.
2) Repetitive clicking on button1 or button2 should load the same tabs next to eachother again and again but it doesn't
3) Thirdly, the main issue is that I m tryin to load another .ascx on loadtab2() which should have webparts in it. I should be able to load an another custom usercontrol into these web parts dynamically. But i m not able to do so.
Here is my code:
