I've tried following the Microsoft instructions to add multiple Textboxes to my form, but just cannot get it to work.Thus, I've deleted everything I wrote, so I don't have code to post. Is there a very simple way to add multiple TextBoxes to a form and be able to index them? If it's too lengthy, Is there a workaround?

I am using VB2010 Express to create a Windows Form.
I have been able to add an event handler to a single textbox to respond to the ".Leave" action.
Now I want to take multiple textboxes and use them as a single control and use the same event handler.
Eg. If TextBox1, TextBox2 and TextBox3 are grouped as a single control nothing would happen in those boxes until focus went to any other control on the form.
I have a form with multiple textboxes and I want the text from the text boxes to append to the current information I have in my dataGridView. How can I accomplish this? I have tried placing the text boxes information in a generic list but I can't achieve passing the list to my function...
Here's what I have tried:
'strPath is a .CSV file which I want to append to
Public Function insertNew(ByVal strPath As String)
Dim writer As StreamWriter = File.AppendText(strPath)

I have a control which consists of a couple of labels and a couple of buttons side by side.I want to add multiple instances of this control to a panel.The problem I have is with positioning/formatting.Whenever I add the control it just gets added on top of the previous one.Should I be using something other then a panel? Are there any tips ot tricks I should be aware of ?

View 1 RepliesWhat syntax do you use to add decimal data held in a NumericUpDown control, and add it to a one dimensional array? Is there a keyword to sum all the items in the array into one number(For averaging purposes)?
Dim heightarray As String()
ReDim Preserve heightarray(0 To UBound(heightarray) + 1)
heightarray(UBound(heightarray)) = heightNumericUpDown.Value
I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.

I have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...
My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.
I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.
Dim pccard As New PC_Card
Dim x As Integer
Dim name As String

"Indexing" an array of textboxes - Control Arrays in VB2008
View 4 RepliesI have a VB2005 project that displays 16 pictureboxes in a 4x4 grid which display CD album covers. In VB6 I could set up a control array i.e. picCD(0) to picCD(15), which made drawing the CD covers a snap. How do I accomplish this in VB2005?
It seems extremely cumbersome to have code like: If Len(path(0)) < 1 Then
If Not IsNothing(PictureBox1.Image) Then
PictureBox1.Image.Dispose()
PictureBox1.Image = Nothing
End If

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 trying to populate a a listview control with items and subitems that a user enters into a group of textboxes on a form. It looks as if some of the code to do this has changed since VB6 and I am confused again. Here is the current code I am using without success:
lvSurgProcedure is the name of my listview control
Private Sub btnAddSurgeProcedure(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddSurgProcedure.Click

I have added a freshly compiled ObjectListView.DLL to my VB.NET project and I've added a ObjectListView control to my form. But, thus far I have been unable to do anything with it except make it throw exception errors of various kinds. I know I'm not supposed to use it using the same syntax that ListView uses, but the documentation for this control is as well developed as MSDN's for ListView--which is to say vague to nonexistent. I can't use ListView because it gives me no control over row height and cell padding. Both need to be minimal, but with the defaults used by ListView, you could move in and and make a living between the entries. Too much space. I need things compact because the application I'm developing needs all the real estate it can get for other purposes.
View 3 RepliesI've got a TCP Listener running on a separate thread. I want to have it log the incoming and outgoing messages in a list on the form instead of in message boxes. I've been reading about multiple threads, and I know there's something extra I need to do because form controls are not thread safe.
Unfortunately I've tried several tutorials on delegates and invoking but it still doesn't seem to insert the log items to the list. I even spent $60 on this Mastering Visual Basic 2010 book to "Build Rich Client and Web Applications with Visual Basic", but there isn't a single chapter on how to handle multiple threads.
I would like to display the multiple records in multiple textboxes Following is my tables and data:

now i want to display the value 10 in one textbox and the value 20 in another textbox and so with the value 30 in another textbox..
Okay this is the simple thing I'm trying to accomplish. I can get richtextbox1 to add to listbox 1. but i cant get both to add. the compare works fine. I'm stumped.

View 8 RepliesI've got two sets of lists with nearly 800 items that I need in 32 different drop down comboboxes (before you ask, that is required and it can't be simplified). Understandably, populating each of them slows down the creation of the form. This happens to be a child form that these drop downs are on and there could be more than one child form displayed. I've assembled the lists in List(Of String) objects and set each of the datasources of the comboboxes appropriately, but it still takes several seconds for them to populate and display for the first time. This is also problematic if the datasource gets updated (items removed, added, renamed) because I have to wipe out all the items and create the list again in all active instances.

View 3 Repliesi have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
