VS 2008 : Making ALL Comboboxes On A Form ReadOnly?
Sep 3, 2009Is there a simple way to make all comboboxes on a form to be readonly upon form load?
Rather than doing:
ComboBox1.ReadOnly = True
Combobox2.ReadOnly = True
And so on...

VS 2010 ReadOnly Combobox Without Making It A DropDownList?
May 10, 2010i have an app that has many suggest append comboboxes in the style of just straight dropdown.
I also clear the text in all of these draopdowns via resettext() in a loop when my user clicks a 'New' button
is there any way to either A:
make the combobox read only (without selecting dropdownlist)
or B:
allow suggest append to fire on all keystrokes instead of only when it sees a match in the combobox....
example: combobox1 contains the following items:
- apples
- oranges
- bananas
as of right now, if my user types in "pears" it won't see any 'P' and won't suggest anything else or even drop down the combobox and allow "Pears" to be entered and because my app does processing only on the items in the list, "pears" then throws an exception....I'm trying to force them to choose only the items in the list and not be allowed to enter anything else while still enjoying the clean look of a resettext() on a combobox
VS 2008 - Selecting All ComboBoxes In Form
Nov 1, 2009I need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do
for each box as combobox in me.controls
But that gave me an error and i now tried this:
for each box as control in me.controls
if box.name.contains("ComboBox") then
...
end if
next
That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.

View 1 RepliesFilter ComboBoxes DataSource Based On Another ComboBoxes Changes?
Oct 28, 2011I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

Apr 27, 2010I have a button that will run a video file in the Windows media player box, first up, is there a way for that video to display full screen on a secondary monitor?My plan was to have a large form that spread across the two screens with the control buttons on one side and the video on the other, is there an easier way to do this? Otherwise I think I might have to look at making an individual form for each screen and then somehow getting the buttons on say form1 to do the work on form2. Again is this hard to do?

View 8 RepliesVS 2008 : Making 'main Window' Form Acting As A Container For The Other Forms?
Mar 17, 2009Am devloping an application with multiple forms, which reside on top of a main form. i.e the main application window. The 'child' forms do not need to be linked in any way as they do not pass information to the parent form, as all the parent form does is act as main window.Now I would like to know what is the correct way for the 'main window' form acting as a container for the other forms? So that all the smaller secondary forms stay focused on top of the main application form, that when the main window is minimized, so these forms should do also etc..
I have read other posts and they mention, leaving all the forms standard i.e. IsMdiContainer = False and then using form.showDialog() to call the secondary forms. This did not work for me as what happens is that as soon as I give focus to the main app form, the secondary form disappears underneath.I tired making the main app form IsMdiContainer = True and when it loads calling:
frmMemberForm.MdiParent = Me
Now this works, because I can click off the form and minimize the app etc and the frmMemberForm doesn't disappear. However if i close the MemberForm and reopen it, it looses this property and once again when it looses focus, it will disappear.

Cannot Get Comboboxes Working Properly Within A Child Form?
Jun 20, 2012I have spent a long time trying to find a solution for the problem I am having with comboboxes within a child form. I'm sure this must be a Microsoft error and not something I'm doing wrong..The best way to explain the problem would be to tell you what I have done so far:
If you open a new Project in VB and add two Windows Forms. Form1 will be the parent. Form2 will be the child.On Form1 add 1 x panel(Form2 will open up within the panel so make sure the panel is big enough to fit Form2) and 1 x button. The only code needed for this form is:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
Now run the program and click button1 to open form2 (form2 should now open within panel1).
The comboboxes and textboxes lose some of there functions for example:
1. You cant set focus on combobox without hitting drop-down
2. You cant highlight text properly in either the combobox or textbox.
3. You cant set the cursor index position using your mouse in the combobox or text box.
Does anyone know a way around this?? Mainly for the combobox as I've got some functions working for the textbox.

(ex: cbo_1, cbo_2, cbo_3, etc...)And using a For next loop to advance through each combobox and update the settings as the for next loop advances.(This might be a stupid way of doing it, but its the first idea that came to mind.)

VS 2008 File Names From Comboboxes?
Nov 28, 2010I have a ComboBox with several names within it. The names are sourced from a database. Once the user has selected a name from the ComboBox, he must input the no. of hours from another ComboBox and then he is able save it to a .txt file through a streamwriter.
Here is a little image I just put together:I want the file name of the .txt file to be whatever is selected from the first combobox. So, by using the example shown above, the file would be called bob.txt. Is this possible?There shouldn't be any save file dialog or anything, I want it to be automated and the name of the .txt file to be selected from the ComboBox.
VS 2008 Dataview Filter Multiple Comboboxes?
Feb 15, 2011This post is a continuation of my other post concerning 'List(of) with multiple comboboxes refill problem.'. I threw the list overboard and began anew with a Dataview.
So far I (finally) managed to get 2 comboboxes (will be more, but if it works for 2...) loaded with the same data using different dataviews (DataView1 & DataView2) so I can select a value from each combobox without the other following the selection.
But now I want to filter out the selected value from the other combobox.
This also works.
The only thing is this: If I select in combobox1 the value 3, and select in combobox2 the value 4, combobox1 will change to the value 2.
If I select in combobox1 the value 2, and select in combobox2 the value 1, combobox1 will change to the value 3.
It works also the other way arround. I can't seem to get my hands around the problem..
Does somehow the index of the items in the combobox play's part? I don't use the selectedIndex, so from my point of view it can't be..
The code I use:
(with the item 0 as 'neutral' option)
