Enabling Buttons After They Are Disabled?
May 13, 2012
I attached a picture of how my project should look and what the labels are. There are a total of 12 books and 4 different age groups. In each age group there are 3 books. There is also a previous and next books button which will show the next book in that age group. I want to make it so that previous button is disabled when it is on the first book of each age group and so that the next book button is disabled when it is at the last book. The only issue that I am having is that after the button is disabled it is not enabled again after. Here is my full code for this part as of now. As you can see I made it so that everytime I click on a new age group the previous button is disabled initially.
I took some unnecessary code out of here because I don't want anyone from my class finding this and coping all of my work.
Public Class BookInfoForm
' use this array to display information in this form
Private books(,) As BookInfo = getBooks()
[Code].....

I am calling a login form from the base form. From the base form I disable it after i show the login form. Then from the login form I want to re-enable the base form that is disabled... I have set it to be enabled at the closing of the login form... doesn't work.. i have set it to be enabled through a collection and calling that base forms handle... doesn't work.. Anything that i might be overlooking?These forms are inside an MDI form..

How do you maintain the appearance of a disabled button in VB.Net? Basically, when I click a button, I want its background colour and font colour to stay exactly the same as before I clicked it.

Alright, I have form, with multiple buttons on it. I want it so when I Click on the Button that Says START it will Change to STOP but at the same time Enable all the Disabled Buttons on the Form. ATM I have this.
Dim ctl As Control = Me.GetNextControl(tbStudio, True)
Do Until ctl Is Nothing
If TypeOf ctl Is Button Then
If ctl.Enabled Then
[Code]...
Works Good, but when I add the btnStartStop.Text = "Start" or .Text = "Stop" to the If Statements, it's always getting stuck on "Stop" I also tried a Boolean statement but came out all funky, EVERY OTHER button was Disabled while the OTHERS were Enabled. I feel like a n00b, I've been programing for a bit now, but just got back into it,

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?

So how does one turn SSL on in System.Net.Sockets.TcpClient with VB.NET code?
Turning it on in System.Net.Mail.SmtpClient is easy, you set the .EnableSsl property. I cannot find a corresponding property in TcpClient. It's probably buried somewhere.

We have an application that is installed and runs just fine on Vista. Our users are requiring a change to our application in order to change the system time on their PC. The code to change the time is as follows:
Private Sub UpdatePCDate()
Dim _ServerTime As Date = GetServerDate()
Dim _offset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(_ServerTime).Hours
[Code].....
When this code executes, it bombs because of UAC. How can we modify our program to display the message similar to when they try to change the system time via the Control Panel. That is, it warns them that something is about to happen that requires their permission.

I am building an application that has a few elements to it but one of the first elements is that when a user selects a date, they have to hit a button in a message box that confirms the date that they selected and then it enables another button. The code is written as such:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles startDateButton.Click
Dim buttondialogresult As String
Dim confirmbox As DialogResult
[code]....
But when I select ok from the Windows.Forms.DialogResult.Ok, it is not enablind the exceptionsButton.

I am enrolled in a class in Visual Basic 2008. I wanted to drop the class, but it is too late. Now, I am stuck with this project that the professor assigned and it's due this Thursday. Anyway, how do I do this: The credit card number TextBox control is dynamically enabled/disabled depending on the choice of payment type? And did I do the newOrderButton correctly (see code below)? This is also the clear button. And is there a way to do a reset Form? Sorry for that many questions. I am really lost right now because there is a lot to do in this project and I don't even have a clue of how I am going to finish this project.
Private Sub newOrderButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles newOrderButton.Click
' clears all the information that is displayed and start over

I have 4 forms. I have a button on form2 that when pressed, I want it to enable a button on form1. What I've tried is this:
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Form1.Button3.Enabled
End Sub
But its telling me that the property access must assign to the property or use it's value.

I am creating a dedicated browser to be used exclusively on a single program located on my hard drive. Security is not a concern as the webbrowser URL will be set to the program's default web page path with no navigation options for going online. The program utilizes dynamic web pages with powerful search capabilities that require ActiveX controls. When I run my browser application, I get a series of security warning boxes stating:
Internet Explorer
An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?
Yes No
Clicking "Yes" allows me to continue and the program features work, but the recurrent warning message boxes are annoying. The default "script errors suppressed" property of the webbrowser control is "false." If I change it to "true" I don't get the security warning boxes but some of the search features on the web pages with ActiveX controls don't work properly.
Is there a way to programmatically enable ActiveX controls in the webbrowser control so that I can set the "script errors suppressed" property to "true" (hence no security warning message boxes) and still allow the ActiveX features to work properly? Or, set the "script errors suppressed" property to "false" and have my program automatically activate the "Yes" button each time a security warning message box is called by Internet Explorer? The goal is to get the ActiveX controls to work in webbrowser without having to click through the warnings.

when I got home to try out the method in the above post in my real application things did not work out.The big difference is that my main form is a MDI. When I open my edit form, it's mdiparent is set to the main form. When I click 'edit' and then disable "me" the entire application goes modal.I was expecting only the MDI child to go disabled, not the whole application..Basically, I want only the MDI child window that opens it's "edit" dialog to go disabled..

is there a setting in the options somewhere that makes the shortcut keys show with the underline when you run the application? In the designer it shows the shortcut keys with the underline but when i run the application it does not show the underline indicating a shortcut key. Now if I push the alt key they show up and they work fine just wondering if there is a setting somewhere that will make them show the underline automatically when you run the application so an inexperienced user knows that there are shortcut keys available?
