This code works fine, the listbox shows the posts. But how do I get the posts on the front side show up as clickable links. Maybe not in the Listbox, perhaps in a panel or similar object?
If objDR.HasRows = True Then
Do While objDR.Read()
ListBox.Items.Add(Convert.ToString(objDR.GetString(1)
Loop
End If
If you want to show it as true links then you can't use the ListBox control. You could use a DataGridView and add a DataGridViewLinkColumn to it.
If you really want to use a ListBox control you could execute the link on the Click event.

I want to add the same Form in project to five tabpages in TabControl.
This is what i have tried
For i As Integer = 0 To 4
'XtraTabPage instance (DevXpress)
Dim page As New XtraTabPage()
'ExamsTab is the existing form that i want to add tho the page
Dim fm As New ExamsTab
fm.TopLevel = False
fm.Dock = DockStyle.Fill
page.Controls.Add(fm)
fm.BringToFront()
fm.Show()
'Adding the page to the TabControl in Exams_Class
Exams_Class.ExamsTabControl.TabPages.Add(page)
Next
This only adds the form to the last tabpage but doesn't add to others.
If that didn't work I'd try page.Controls.AddRange(fm.Controls) but I'm not in a position to test it.
In the past when I've wanted to keep my code better organized into one form per tab I've:
made a new form
put a tabcontrol on it with a single page, call the control TheTabControl for example
put all the controls into the tab page, put all the events etc in the form code
put a line of code that retrieves the tab:
Public Function GetTab() As TabPage
Return Me.TheTabControl.TabPages(0)
End Function
on the main form, with the one tabcontrol that should contain all the other tab pages, have a code like:
MainTabCobtrol.TabPages.Add(New SomeOtherForm().GetTab())
This way all the controls and their event handlers stay in one form (a good thing) but you can combine them together into one Tab Control on another form. Putting them inside a tab means you can get an idea of how to size it, and you can specify in the designer other things like the tab name etc
From a code organising perspective, it's something the designer can more easily cope with than having all the TabPages in one. Control and all the event handlers etc (makes for a fairly monster form code behind and it doesn't respond well to being split into partial classes)
If you want to add a tab control to the existing form the Document Outline window might be helpful for moving the controls into it with drag and drop. You could also cut all the controls, add a tab and paste, but check the eventbhabdlers are all still wired up afterwards- I find that sometimes this makes them go missing
I have searched several forums but did not find answer for checking whether ComboBox is already DroppedDown via VBA code.
I have other code on Form_KeyDown events due to which anytime I press vbKeyDown it moves to next record. I need to check if ComboBox is DroppedDown then don't use other code and instead treat the default functionality of access where vbKeyDown will start scrolling through the items of ComboBox displayed in DropDown.
There is no such property, neither an event for OnDropDown or similar.
If the combobox has focus, you can force a dropdown using the DropDown method, but that's as close you can get.
I am using Access Database to make a program.
Here is the problem:
After I enter the data in textbox, which is in a blue boxes, and click 'Add Data' button, data move to the ListBox, which is marked with orange box. But I should press 'F5' button(refresh) to see the data. I want to see the data immediately after I click 'Add Data' button. Is there any way to do that?
Any comments would be greatly thankful(It would be nice if you can share your code)
Add ListBox.Requery to the button's click event right after new data has been added to the ListBox.
Private Sub YourButtonName_Click()
'Add data
Me.YourListBoxControlName.Requery
End Sub
requerying the form is the simplest way probably, but with no idea of what the button does, how your data is structured, how the form is structured, i.e. is the listbox bound or unbound, so cant really say, if F5, is doing it, then just look for the VBA method for refreshing the form.
Okay so I've been searching for a solution for a while but can't seem to find any answers tailored to what I need to do. Also this is my first post here so I'm sorry if I'm being to vague with what I need. Basically I'm creating a program that has a few text boxes on one form and I need to display the data in those text boxes into a list box on another form. There's a button at the bottom of the first form that allows me to switch to form 2 and also display the data in the list box. I can switch to form 2 but nothing shows up in the list box. I also have a few radio buttons and check boxes on form 1 that will affect which constant values will need to show up in form 2's list box as well. One other thing is that I can't just use a form load option for getting data in the list box, it has to happen with the button press because I will be switching between forms and from my understanding the form load option only works once when the form is loaded for the first time. Anyway here is part of my code for form 1 that shows the button click:
Dim strCustomer As String
Private Sub btnPlaceOrder_Click(sender As Object, e As EventArgs) Handles btnPlaceOrder.Click
strCustomer = txtCustomer.Text
frmInvoice.ShowDialog()
frmInvoice.lstCustomerOrder.Items.Add(Me.strCustomer)
End Sub
My first form is frmMain and my second form is frmInvoice. Can anyone please help me with what I need to do differently with this code and what exactly I need to have for my code for form 2 to make this work. Again I am somewhat new to this so I'm sorry if any of this seems vague or if I'm not quite posting this is the right way. Also I'm using VB.
The code you provided should work fine but you are modifying the ListBox after you show the invoice Form. Since you are using showDialog(), the code that follows this statement will only be executed once the dialog form is dealt with (for example if you close it). This means that if you click the button a 2nd time, the ListBox should contain one item. If you switch the two lines so it looks like this, it should do what you expect it to:
frmInvoice.lstCustomerOrder.Items.Add(Me.strCustomer)
frmInvoice.ShowDialog()
How to capture the popup when clicked when the button is clicked in webbrowser it opens a popup webpage i need to capture the popup webpage to the tabcontrolbrowser
I think I understand what you are trying ask for. I have had a similar issue where I must display a form nested within another form. To do so I have used code similar to this:
aForm = New TLoginForm
aForm.TopLevel = False
pnlLoginPanel.Controls.Add(aForm)
If aForm.WindowState <> FormWindowState.Maximized Then
aForm.WindowState = FormWindowState.Maximized
End If
aForm.Show()
I like using a panel control to contain the form I am instantiating. It is just easier for me to understand the bounds of the form when it is getting displayed and it is easier to use a panel control's Controls.Add ability than a tab-page's alone. When I am using a log-in form or another type of form nested within another form I create a panel control to 'hold' the form inside and provide bounds for it to be displayed in. Then the TopLevel property of the log-in form must be set to False so that the form I am displaying knows it will not be displayed on its own as a top level window. Be sure to do this as an error can be encountered otherwise. The WindowState.Maximized is to ensure that the form fills the panel.
