Visual Basic: How to replace selected NumericUpDowns with ComboBoxes - vb.net

Is it possible to replace the selected NumericUpDown controls with ComboBoxes?
I understand that not all properties can be conserved but the only properties I need are the location and the size.
The workflow I have in mind is as follows:
Select certain NumericUpDowns
Click replace with... and then select ComboBoxes (or any other approach)
Where the NumericUpDowns were, there are now ComboBoxes of the same size
The reason I want to do this is that I have to put together a GUI with multiple tabs. Each tab page has a list of Labels with either NumericUpDowns or ControlBoxes next to it. The order of the controls changes per tab. I just want to copy the items on the first tab and paste them on the other tabs. Then per tab I only have to change certain NumericUpDowns into ComboBoxes.
I started with VB yesterday so I might be overlooking something.

The quickest is doing it manually, we cant change your GUI remotely - since you are at an entry level with a language you do not know well, RAD is the best recommendation - this way you can study what it does - just like learning HTML with DreamWeaver's RAD tools.
Since your interested, (I know your new to VB so I'dd make it heaps clear) you do these steps:
a) Open Winforms VS 2008 solution
b) Click the File > Create New Project > WinForms
c) Double click the form and it will show you the forms code
d) Then in the constructor method you will see the line InitializeComponent
e) Right Click on this method call and chose Goto Definition
f) This will show you the code that populates the form with controls
g) Then for each form I'm suggestion you replace all the NumericUpDown's with ComboBoxes in the xyz.Designer.vb file
However I'd really recommend doing it with Visual Studio IDE. Don't be frightened.

Private sub Replace_By_ComboBox(ByVal nud As NumericUpDowns)
'Create new combo box
Dim cbx As New ComboBox
cbx.Left = nud.Left
cbx.To = nud.Top
cbx.Width = nud.Width
cbx.Height = nud.Height
cbx.Visible = True
cbx.Enabled = True
'Add the combo box
nud.Parent.Controls.Add(cbx)
'Remove the NumericUpDowns
nud.Parent.Controls.Remove(nud)
End Sub

Conditional visibility on MS Access Form - how to write in VBA or Macro

I have some very (very) basic MS Access knowledge. I'm trying to expand a bit into either VBA or macros as I'd like to put in some conditional visibility for my form. Basically, I have a checkbox. If it's checked, I want three or four more fields to pop up. Someone was able to point me to a basic VBA formula of if (this checkbox) = true then, (fieldx).visible = true, else, (fieldx).visibility = false, end if.
But I'm so new to this that I need more help and explanation. I tried putting it in but couldn't get it to work (no error message, just nothing changed at all).
Specific questions:
-Does this formula seem right?
-If I want multiple fields to be visible, can I combine them into one formula or should I create a new "if" statement for all?
-Where do I enter this code? I'm running the Office 365 version. For all I know, I'm not even putting it in the right place.
-How do I determine the field names to replace the (this checkbox) and (fieldx) in the formula? I tried entering the name I title the fields as, but with the spaces in the name I got an error message, and without the spaces nothing happened. Is there a specific naming convention to turn the field names into formula-appropriate titles? Is the name listed somewhere?
-Once I get the formula entered, is there something I have to do to get it to run/take effect? I tried saving, closing and reopening with no changes.
-Is this the best way to go about this?
If there's anything else you think I should know, I would love to hear it - but please keep in mind I'm very new to this so if you could keep it at "dummy" or ELI5 levels of explanation, I'd appreciate it!
after creating a form with 4 textboxes and a checkbox put the form in design mode (lower right corner has design mode selected, select a textbox and hit property sheet on the ribbon (or f4).
On the property sheet note the visible property. set the visible property to false. Now the textbox will be invisible when the form starts.
Tip you can select all the textboxes at the same time and set their properties all at once.
Every control on the form and even the various parts of the form have properties you can set and play with. For instance you can give any name you want to any control. On the property sheet go to the other tab and set the name property.
Tip: choose a name you you will remember without having to look it up and describes the controls function.
Next select the checkbox (not the checkbox's label). On the property sheet go to the event tab and select the on click event. hit the ellipsis and choose code builder. Access is Event Driven. We want the textboxes to appear when the checkbox is selected so we put that code in the checkbox click event.
after choosing code builder we get the code window where we can browse among all the events for all our forms. for now all you should see is something like:
Private Sub mycheckbox_Click()
End Sub
So insert some code to handle the checkboxes like:
Private Sub mycheckbox_Click()
If mycheckbox = True Then
txtbox1.Visible = True
txtbox2.Visible = True
txtbox3.Visible = True
txtbox4.Visible = True
Else
txtbox1.Visible = False
txtbox2.Visible = False
txtbox3.Visible = False
txtbox4.Visible = False
End If
End Sub
now when the checkbox is not checked no textboxes are visible.
but when the checkbox is checked they appear

move items to the another listbox which is searched by textbox

I am beginner at programming. I'm trying to build a form based app using visual basic according to a example in youtube.
In the form I cant move a item from listbox1 to listbox2 which was searched in textbox2
When I write the first item which is placed in first row of listbox1 it moves item to listbox2 but if I try with another item it cant move to listbox2.
I would be happy if someone can help me about this case.
Here are a picture of my form and the code I use :
a Lot depends on what you are putting into the listboxes. If it is simple stuff like a, b, c, d etc it will add everything to listbox 2 as you have your code under text_changed event. Try and use a button when user stopped typing to search for the entire word.
Also add your text after the sc Call to your sc sub before the return statement as well -
Sub sc()
''Current code
''If Textbox2<text - remove, already called...
Listbox2.Items.Add(Listbox1.Text)
Listbox1.Items.Remove(Listbox1.SelectedIndex)
Return
End Sub

Explanation of vba code in a word document having .docm extension

I have a Microsoft Word document with .docm format. A first glance it does not contain any macros (as when clicking the following on the ribbon; View -> Macros -> View macros pops up a window having an empty list).
But when enabling the Developer ribbon tab, and clicking the Visual Basic icon there, and then selecting the Document and ContentControlonEnter from the dropdowns in the VB window the following code appears:
Private Sub Document_ContentControlOnEnter(ByVal ContentControl As ContentControl)
Dim i As Long, j As Long
With ActiveDocument
If ContentControl.Title = "Classification" Then
ContentControl.DropdownListEntries.Clear
For i = 1 To .ContentControls.Count
If Left(.ContentControls(i).Title, 5) = "Level" Then
j = j + 1
ContentControl.DropdownListEntries.Add Text:=j & " - " & .ContentControls(i).Range.Text
End If
Next
End If
End With
End Sub
Selecting the other options in the dropdowns give only "blank" code (that is they contain only function declarations followed by theEnd keyword).
My question is what is the code meant to do?
*
Details:
The Word document in question contains hyperlinks to parts of the same document and a couple of links to Word files and Excel files of the same folder. It also contains lots of content control boxes, which I'm guessing is the focus of the code (as the code contains the ContentControl keyword)
Content controls can trigger macros when the user enters and exits them. Microsoft made the design decision that all content controls should trigger the same "events" - Document_ContentControlOnEnter / Document_ContentControlOnExit - and that the code in the event needs to check which content control was entered / exited.
Content controls are considered as part of the Document because the Document can trigger events. That's why they're in (and MUST be in) the ThisDocument class module.
(Note: View Macros can only show you PUBLIC SUB procedures with no arguments that are located in "normal" code modules. Any Private Sub, any Function, anything that takes a parameter and anything in a class module will not appear in that list. So you can't use that list to determine whether a document contains any code.)
The If ContentControl.Title = "Classification" Then checks which content control was entered. (Note: it usually makes more sense to use Select Case rather than If, especially when the event needs to distinguis between multiple content controls.) What's inside the If only executes if it was a content control with the Title "Classification". (Note that more than one content control can have the same Title, so more than one content control could run the code.)
If another content control is entered, the event is still fired, but nothing happens (in this case).
Catalin Pop correctly explained that the code is, in essence, "resetting" the drop down list.
Legacy Form fields use a similar pattern - macros can fire when the user enters/exits an form field. But the design for that was you had to create a Public Sub and assign that to the form field in the Properties.
I think the logic here is quite simple.
Basically the code searches for a content control named Classification within the entire document.
After it finds it, it clears all of its drowdown entries - like a reset.
After the cleaning part it again searches through the entire document for all content control that start with word "Level" and it collect the text for those controls and their order in appearance.
With this info collected it then fills the dropdown optios for the classification control above. (e.g. 1 Level X, 2 Level Y.. - based on what it finds in the document for controls starting with Level in their name)

Fill in a text box when selecting a combo box option on Access

Im not very advanced in Access and I am struggling with defining the VBA code/expression build/ or Control Source for an instruction that can make the following isntruction:
If i make a selection on a Combo box (with my key field "TypeService" on my table TblMain)
Then; my text box is able to return the TypeConfig rows related to the TypeService selected before (my table TblConfig contains TypeServiceFK and TypeConfig fields)
So, my objective is to get a dynamic textbox that depends of a multi option combobox.-
Thanks for the help!!
Put a listbox on your form, let's say it's called List2, and cancel the wizard if it pops up.
In the Row Source property of the listbox, put this SQL statement
SELECT tblConfig.TypeConfig FROM tblConfig WHERE (((tblConfig.TypeService)=[Forms]![frmMain]![Combo0]));
This assumes your form is called frmMain and your combobox is called Combo0, so change those as necessary.
Right click on Combo0 and choose Build Event, then Code Builder. Replace the Sub...End Sub stub with
Private Sub Combo0_Change()
Me.List2.Requery
End Sub
Now every time Combo0 changes, the SQL statement behind List2 will run and return the TypeConfigs associated with that TypeService.

Ellipsis Textbox for VBA Userform File Select

I am trying to create a path selection user interface for an extensive VBA program I've been working on, but I can't seem to get the ellipsis textbox that I'd like. This is a very common feature, especially in option tables. This is an example of what I'd like to get, straight from the VBA Options panel:
I would LOVE to find a way to get the same functionality in a Userform. The only solution that I've found thus far is to use a combo box with the ellipsis arrow option enabled. However, there doesn't seem to be an apparent way to use the activation of the combo box arrow to run a dialog box, nor does there seem to be a way to make it look UNLIKE a combo box. Last resort I use a button below the text box, but I'd really prefer a less-bulky way of doing this.
Any solution would be greatly appreciated.

Your suggestion does work, and it is surely less complex and more elegant than having two controls work together, Button + Textbox.
A Combo can achieve perfectly the desired feature, in the following way.
1) In design mode, set the button style to Ellipsis
DropButtonStyle = fmDropButtonStyleEllipsis
And eventually, make the ellipsis show up only when the combo is entered, by setting the design-time property:
ShowDropButtonWhen = ShowDropButtonWhenFocus
2) If needed, you can set other design-time properties to have some look and feel. The defaults look pretty good however.
3) Add the following handler to the parent userform. The snippet simulates the launching of a dialog and getting a new value or cancelling. It does not show any dropdown window. (but you still have control over that: if you want to show it according to some condition, you still can call the method ComboBox1.DropDown)
Private Sub ComboBox1_DropButtonClick()
' The following two lines avoid to call the routine twice, at entry and at exit
Static i As Integer
i = (i + 1) Mod 2: If i = 0 Then Exit Sub
With ComboBox1
s = InputBox("enter some text", , .Value) '<~~ simulates any dialog
If s <> "" Then .Value = s
SendKeys ("{Enter}") '<~~ to close immediately the dropdown window
End With
End Sub
Try it ;)
Not only do ComboBoxes have Drop Buttons, so do TextBoxes (as do Excel's RefEdit controls). Even though you can't access the Textbox's Drop Button at design time, you can do so at runtime. Using a textbox avoids having to deal with the dropped down list of a combobox.
Given a textbox named TextBox1, the following code will provide the desired ellipsis drop button:
Private Sub UserForm_Initialize()
With Me.TextBox1
.DropButtonStyle = fmDropButtonStyleEllipsis
.ShowDropButtonWhen = fmShowDropButtonWhenAlways
End With
End Sub
Then use the DropButtonClick event of the textbox to perform whatever action you want:
Private Sub TextBox1_DropButtonClick()
'' Code here to do what you need
End Sub
I have an extensive example at Alternative to Excel’s Flaky RefEdit Control that uses a textbox with a "Reduce" drop button to replicate the functionality of Excel's unreliable RefEdit controls.
