TabPage1
Panel1
textboxStepDesc

Since textboxStepDesc exists in Panel1 in both TabPage1 and TabPage2, how do I specify that I want to retrieve the value of textboxStepDesc.text on tabpage2 vs. textboxStepDesc.text on tabpage1?
I am trying to print multiple tabpages each as its own page. The problem that I am running into is that it will only show the last page loaded in the print preview.

Me.PrintPreviewDialog1.Document = Me.PrintDocument1

I've tried hiding one tabpage in the form and it was somehow successful. However, it was not the one i'm planning to do with my program. I don't know if there exists any code that could make the tabpages(two actually) automatically hide when the form loads and would only be visible after some passing some conditions.
View 1 RepliesI'd like to print preview and print 3 tab pages from a windows form. Below is my code. I was able to get it to work if it's only one tab. but not 3 tab pages. [code...]
what can I do to make it work? also if there's an entirely different way.
I have a project where I need to add TabPages to a TabControl. I have a Panel with 10 checkboxes on it and I want to replicate that onto each TabPage as it is added.What I get is it is added to the first page, then when I add a second tabpage, the panel is moved there and not replicationed even though I used the (Add) method.

I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something
View 8 RepliesI am using KeyPressEventArgs to restrict several text boxes to numeric entries only. Rather than repeat the code, I thought I would make a "RestrictToNumeric" subroutine and call it from each "KeyPress" event. Like So:

RestrictToNumeric()
End Sub

The problem I am encountering is that the variable 'e' is used before it has been assigned a value, causing a null reference at runtime.
So I tried to add Dim e As System.Windows.Forms.KeyPressEventArgs As?to the RestrictToNumeric sub.I cannot figure out what I need to "Dim" it as...
We have several VB.NET websites running internal applications. These sites are often modified with minor changes, and are maintained on the server as uncompiled code. I'm looking for the best way to maintain classes so that we can reference them from multiple websites.
Specifically, we're looking to put some common functions (error logging, common database calls, etc.) into a centralized location where they can be maintained separately from the sites and called as needed. And we'd prefer to have this on the server as uncompiled code, so it can be uploaded without precompiling. I feel like I'm missing something obvious, but what is the best way to set this up?
I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?
I have a button 'start quiz' which uses the dataset to fill the quiz form - ready for the user to start answering the questions.However, I am getting a 'null reference' at the point where the 'navigate records' on the quiz form is called.

Is there a way to write a single function that will control validating the input to any textbox? How to pass control of it.
E.g.: My second try was to:
Dim CurrentTextBox As TextBox << Declare a global
Write a function that uses the global textbox and takes in 2 parameters, one determining the length it has to validate and the second telling it what to do once the input is verified
Public Sub ConfirmInput(length As Integer, which As Integer)
If (CurrentTextBox.TextLength < length) Then
CurrentTextBox.BackColor = vbRed
GoTo DONE
ElseIf (CurrentTextBox.TextLength > length) Then
CurrentTextBox.BackColor = vbRed
[Code] .....
My first try was to pass a textBox parameter to the ConfirmInput function but I believe that's the same problem as above.
I am in vb.net and have a function that will be accessed by multiple threads. Everything inside the function uses local variables. However, each thread will pass in its own dataset by reference. From what I have read the local variables should be no problem, but I think the dataset coming in is a concern. How should I control access / execution of this function to make sure that it is thread safe?

I have several buttons on the form with standardized names (minExpandOSD, minExpandSettings, etc). All the buttons names start with "minExpand" and the last portion of the button name is always the same as its parent (a group box). Each of the group boxes also have a standard name (GroupOSD, GroupSettings, etc).Each groupbox has a minimize/maximize button. I have many group boxes. Rather than copy the same code block for each groupbox, I am trying to write a sub that can be called for each of the group boxes.
