I have the following class. Basically, i want to populate a bunch of comboboxes. So i want to return an Id and description column almost all the time.
Public Class combodata
Private _id As Long
Private _description As String

how can I return the items as an array. Is converting to an array the best way? I will need to populate a combobox with the returned result
I have 3 comboboxes and want to populate each from XML. What is the best way to do this?Here is the XML:

I am trying to move over vb6 code that worked through arrays of comboboxes.I have a panel that has 18 comboboxes that each need to be populated the same.I first clear the combo boxes and it loops through them, but keeps going until it gets an error.Likewise on sFillLotNO, it adds the first foundrow to each but bombs out when it tries to get the 19th.[code]
View 2 Replieshow you populate cascading comboboxes? I have one combobox on one form, from which I'm trying to populate another combobox on another form. The first combobox contains Locations while the second combobox contains offices for whichever location is selected in the first combobox. I would like it to work as follows: user clicks on first combobox to select a location, and then the second combobox lists all the offices for that location.As of right now, the second combobox is just displaying the first office that is in the first record for the respective database table it is pulling from.
View 2 RepliesI have a form that lists all of the clients in a DataGridView and when I click on a column that is a Link I want the data to populate into the form I use to capture. My problem is that when I click on the link all the TextBoxes on the form are filled correctly but my ComboBoxes are not.[code]
View 1 RepliesHow I can populate a combobox (combobox2) based on the selection made from another combobox (combobox1)? They are on different forms. Combobox1 lists locations, while combobox2 lists offices for each location. I would like it to work so that when the user clicks on combobox1 and makes a selection, the 2nd form loads with combobox2 showing all the offices for the selected location.
View 6 RepliesI am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET. I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes.
For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. [Code]
I have four comboboxes in my Ist form related to course as.c_type,c_stream,c_major,c_nature.......combobox c_type contains the type of courses like degree,diploma, PG etc,similarly "c_stream" contains stream like engg,medical etc. further c_major contains all courses like computer engg(CE),mechnical(ME), physiotherapy etc. and last c_nature has course nature whether regular or private or distance.Now situation is when i select diploma from c_type, corresponding options must be populate in c_stream like engg. And now when i select engg., CE or ME must be there in c_major combobox .Same is for C_nature.The all 4 combobox must show "please select" text on form load event..i also have 2nd form where i have same combobxs. so is there any way to call the same code without again writing that to 2nd form.
View 1 Repliesthis 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):

I 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.

im calling a bunch of different propertys named K0 to K6, im using a string to check which one i need to access, this is damn messy, how can i do it in a more clean way? Im convinced that strings are not the way to go so please give me a comment to get in the right direction.
Dim tempAntDec As Integer
Select Case wd.MClass
Case "K0" [code]....
I would like to call this in some other way like, this.. or dont know but i feel like there is a better way to handle this?
tempAntDec = wd.allMeasUnc.KValue.antDec
In my classic asp app, I have a markup page with a bunch of checkboxes. The checkbox control ID is bscv.Once a user checks a box and clicks submit, the value is processed on the next page called next.asp.Based on the value of the checked box, I display the correct dropdown.I use the following code on next.asp to display the correct dropdown.
If bsvc = "master" Then
' only master was checked
' "If the user checks only master checkbox, ...txtmaster with 2 options... is displayed."
%>
<select id="txtmaster" name="txtmaster">
<option value="">-Select a service-</option>
<option value="1">1</option>

I need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
<TablixRow>
<Height>0.23622in</Height>
<TablixCells>
[Code].....
and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.

I am developing an automation tool which is reading the file path from an Excel workbook and after launching the application I am firing print job using SendKeys.SendWait() for Ctrl+P and Enter key. Now the Problem is, I am facing synchronization issue for launching the application and handling the print procedure keys.Sometimes Applications are launching little late(like Excel and MsWord files), so at that time I am not able to find till how long I have to wait for a successful launch of the Application. Anybody have any Idea how to check this waiting time till how long I should wait to fire CTRL+P and then after getting PrintDialog ENTER button ?
View 2 RepliesI've got a listview with a bunch of items which all use checkboxes. Each time an item is checked or unchecked I want to save the selection. Whilst saving/loading the selection is not an issue, I can't seem to find an event which triggers AFTER the checked item has been changed. For example, the ItemChecked event will fire when an item has been checked or unchecked but the event will give it's checked status BEFORE it was changed. I've had to resort to saving the list when it loses focus but this isn't ideal.

If I need to read a bunch of items from the Registry, the following gets tiring fast:
Dim item1, item2 As String
item1 = My.Computer.Registry.GetValue(KeyValue, "item1", Nothing)
item2 = My.Computer.Registry.GetValue(KeyValue, "item2", Nothing)
Is there a smarter, more compact way to do this?

I would like to actually SORT the controls, depending on some values.

View 7 RepliesI am creating an instance of a Generic List collection and I am surprised to find that I can't add more than one value to it at a time. I was thinking there was going to be something like what you can do with arrays, where you can add a group of values to it at creation. I saw the AddRange method, but that seems to add another collection to the end of this collection, which is not what I want. So my code is:
vb
Dim MyList as New List(Of String)
MyList.Add("John")
MyList.Add("Bob")

Ok I have a datagridview that shows a bunch of data through a Database. So I have the script connect to the database and I have a while loop going so that it keeps searching through the database to make sure it "publishes" all of the data in there. My problem is, it doesn't show the first set of data. For example: I have 2 columns, one header is Name, and the other is Y/N. The data in the database:
Jim, N
Alex, Y
Pat, N
George, Y
When I run the program, and it populates the datagridview, the first set of data is removed, so it only shows Alex, Pat, and George. Does anyone know why this happens? Does it perhaps have something to do with the column headers writing over the first set of data?

I've written a very simple form application that launches a bunch of shortcuts. There's one particular one I want to launch, but it's got a lot of switches with special characters. I can't figure out how to make the switches/arguments into a string so that VB2010 will pass it to the executible cleanly.. Here's what I did, I'm sure it's laughable, but I guess everyone starts somewhere:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
Dim MyString As String = ","/CitrixShortcut: (1) /QLaunch "CHCFarm:Citrix Console""
Process.Start("C:Program FilesCitrixICA Clientpnagent.exe",MyString)
End Sub
