I have 3 Combo boxes that have number 1-9 in each, i would like to make it so that if the first one is set to 9 then the and the second it set to 8 then the first 1 is set to 1, i need them to only equal 9 through all the boxes?
View 6 RepliesThis one is causing me a lot of frustration, and as far as I can see, it should work. What I have is a form with 9 ListViews (ListView1 through 9), and I want to add items to them.The issue is, I have a routine that sets which ListView to use. Say I have set it for ListView4, it works initially on the first file, but after one line of code. it reverts back to ListView1 for the remaining files. (itmModelItem = lvwModels.Items.Add(ModelName) in AddModel.

Yesterday s**ked, and today ain't (sic) looking better. I have an application I have been working on and it can be slow to start when my ISP is down because of DNS. My ISP was down for 3 hours yesterday, so I didn't think much about this piece of code I had added, until I found that it is always slow to start. This code is supposed to return your IP address and my reading of the link suggests that should be immediate, but it isn't, at least on my machine.Oh, and yesterday before the internet went down, I upgraded (oymoron) to XP SP3, and have had other problems.So my questions / request:
1. Am I doing this right?
2. If you run this on your machine does it take 39 seconds to return your IP address? [code]
I have another problem:

Bolded line makes an exception: The remote name could not be resolved: 'unkn' I guess it has to do something with threading, and path doesnt generate correctly username, password, and pth are generated from objects in another form, so i did it like this: Dim newfrm As Form1
And then acces the objects that hold user, pass... like: newfrm.textbox1.text
So, why do i get this exception then if im doing it the right way, and how do i get this to work?

Hi
I have a thread that it calling many processes.
While the processes are executed (spends some seconds or minutes in completing all the tasks) I show form "Please wait to complete all tasks".
But one of these processes I have to show a form because the user has to choose a few data. But the problem is that this form is showed minimized.
Already I have tried to show it maximized and to bring it to the front but it does not do it.
how I can show this form to front and maximized?
My actual code is:
f= New frmLPlantillas
f.WindowState = FormWindowState.Maximized
f.BringToFront()
If f.ShowDialog() = DialogResult.OK Then
value1= f.xxxx
value2= f.zzzzz
value3= f.aaaa
value4= f.bbbbbb
Else
Return False
Exit Function
End If
Thanks in advance.
this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

View 4 RepliesI 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.

I need to build a SQL statement.
I have 3 ComboBoxes that i need to use for my SELECT statement. This means that if the user selects ONE of them the SQL statement will be different than when he chooses TWO or THREE.
If none is select, then ALL data is displayed.
I have a program issue I am trying to work on. I have multiple comboboxes(12 total) on a form.I am attempting to update some settings from what ever the user selects from the combo boxes. I am trying to keep the code as small as possible, so I thought about having all the comboboxes have similar names only different by a number being changed at the end. (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.)

I 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.
1) Does this code make text the selected items text? If it doesnt then how would I do that?Dim text As String text = ListBox1.SelectedItem.ToString()
2)How would I make it so that if in combobox.items there is an item with the same text as the listbox selecteditem it is removed? This is what I have and it doesnt work.
If ComboBox3.Items.Item(text) Then
ComboBox3.Items.Remove(text)
End If
I 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.
This showed up this morning in my error list.

I have a combobox on my main form and it lists geographical locations that the user creates. How do I make the combo-boxes on the sub forms match the one on the main form?
View 1 RepliesIs 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...
This 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:

I'm trying to make a program in which I can import an excel file, read the whole thing and save it in another format. So far so good: can import the file, read it, skip first line or not etc.But.. Now I've been thinking about a sort option.What if the column order of the excel file is in another order than the export file must be in. In stead of opening the excel file and rearrange the columns manually, I would like to sort it in the program. Just for the sake of trying to make it work and gain experience
So, i read the first line which contains the column names and put them in several comboboxes where I can make a selection. No problem here.Now, the selection of combobox1 has to be removed from the other comboboxes and so on, to avoid double selections on one column. That's where my listOld comes in. Everytime a selection is made in a combobox, a sub is called to create the listOld and create the listNew (which contains items you can still choose from).As I make more selections the listOld gains more items and the ListNew grows shorter.But here comes the part where I'm puzzled.In the part "refill the comboboxes" (bottom part) when I disable "cmb2.Items.Clear()" the listOld (previous selected items) contains all selected items correctly.

I'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]
