I'm making a program in which there is a form and when opening this form it automatically checks the internet for a csv file and reads the data from it.
the csv file consists of 2 items i need "Provider name , Provider smtp" example:
==
Chello,smtp.chello.nl
Het Net,smtp.hetnet.nl
==
I've got the part working that when the form loads the online file gets read and the data is shown in a combobox. Only it shows the whole line like 'Chello,smtp.chello.nl'.
What I want (and can't seem to get working) In only the combobox the words before the comma and in a invisible textbox the corresponding smtp line. Ergo when I select option number 4 the right smtp is put into the invisible textbox.
My code so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim myWebClient As System.Net.WebClient = New System.Net.WebClient()
I would like to combine the two things in the title to use as a query for an access database. I think i kind of know what to do, but then it doesn't work so i actually dont, the error i am getting in runtime is that the query is incomplete. The line of code in question is this:
Query = New OleDb.OleDbCommand("Select key From '" & frmFrontEnd.cmbModel.SelectedIndex.ToString & "'_Assistant", AccessConn)
I have 3 textbox's and 1 dropdownlist and I am trying to combine all that data into one string. Here is what I tried but is not working:
Private Sub FullAddressTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles FullAddressTextBox.TextChanged FullAddressTextBox.Text = AddressTextBox.Text & " , " & CityTextBox.Text & " , " & StateDropdown.text " , " & ZipCodeTextBox.Text End Sub
My goal is to combine these simultaneously as whoever is filling in the data or after I hit my submit button, if so it has to occur as the first event.
I think my problem has to do with .text after the statedropdown, Is it suppose to be .tostring?
I'm trying to combine two arrays. Simply append 1 array to another. I have two string arrays. Lets just say array1 and array2.would the following be correct?
array1.Copy(array1, array2, UBound(array1)) I guess I'm slightly confused about the parameters. When I try to use the above code I get green squigglies with the following error.Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated.
I have a form with a DGV bound to a SQL database. the DB has three colums: ItemCode, ItemName, Status. The Itemcode field is a combobox complex binded (if this matters). How can I have the ItemName colum auto insert the text for the ItemName colum when I select the associated ItemCode with the combo box.
This next program I am working on consists of 3 listbox's. The idea is to have the end user load names in the first and second list box. Then have a button's action when pressed combines the list in listbox1 with listbox2 then gives the output combination in listbox 3.
I also wanted to include some checkbox options such as adding a "_" or "." for every item.
Probably an easy question to answer...I have 9 buttons on my form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click etc. and all do the same thing so how can I merge them into the same sub so i don't have to copy and paste a bunch?
As far as I know , it is possible to combine projects into a solution . So , lets say we have 3 projects . Each project has a starting form , lets call them SF1 , SF2 and SF3 .What I would like to ask you is how can I write code in order to have both the solution and the partial projects , working . You see , the solution (which as far as I know will also be accompanied by a new project) has to have a starting form ; lets call it SF0 .A) First of all I'd like to know how can I call a partial project from the solution itself .B) What code do I have to write in the partial projects in order to keep them running correctly when they are separate (that is not part of the solution) . I am asking this question too , because as I guess , there has to be code in SF1 , SF2 and SF3 (into buttons) that lead back to SF0 , but
I am binding the data from combobox to textbox.In the Combobox Click event i coded as below for binding:[code]In the above code only the first value is showing in the textbox but when i select next value in the combobox the value is not changing..Is any loop i need put for binding? B`se i need when ever i change or select the value in the Combobox then the corresponding value should be change in the Textbox.
I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.
I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

I'm a long time VB.NET developer and has recently switched to C#. I found out that some of the built-in VB.NET functions (which predates .NET back to 6.0 and BASIC itself) such as the String.Left, or Right, or advanced functions like saving to the registry (SaveSettings and GetSettings) are noticeably absent. What I did was create a new project in the same solution with VB.NET as its language and recreate basically all the functions I need that are available in VB.NET. And then I just call that to the C# code I'm writing.Since compiling the code in .NET pretty much boils down to the same CIL, it shouldn't matter performance-wise what language I wrote the code in or whether I mix C# with VB.
how do i change the display member of a ComboBox after i have entered a code in a textbox that it represent the combobox value?example
Code: 02-001 Combobox: Provider X
if i change the code the provider combobox must change and if i change the provider combobox the code should change!..
if e.keychar = chr(13) Then combobox.valuemember = textbox.text combobox.displaymember = me.stockdataset.selectprovider(@textbox.text) end if
this code change the combo box display member but if I change the comobox by clicking it the code on the textbox doesnt change, to its corresponding code...the combo box is bound to the provider tables....
I am trying to display an ID which is a primary key in my table by selecting the corresponding name in my table. the names have been saved in a combo box and depending on the name selected the textbox will display that Id. the code I have so far only gets the names from sql server but doesnt show the corresponding id in the textbox. I have been searching and cant find anything similar to this.
this is the code for combobox. i placed it in the formload
In my program when combobox name is changed the combo box next to it automatically selects the correct price, but the user has the ability to change the price from the list. CBPrice is populated by an access database (for this I used the wizard to set up a connection etc.) this all works fine. My problem is that I am trying to get the value from CBPrice into a text box, here I managed to get a code string that will allow the combobox value to be converted into a string (which was an error I was getting for a different part of the program) but now when I select a name from the combo box CBName the text box goes to 0 instead of the value that is inside CBPrice like it should...
This is my current code... Private Sub CBName_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CBName.SelectedIndexChanged Me.Txtoutcome.Text = Val(Me.CBPrice.SelectedItem.ToString())
I am unable to initialize textbox and combobox in my form when i click on the binding navigator 'New' button. Why is it so? But at the same time the datetimepicker does!ere's the code:

I have a form with a DGV bound to a SQL database. the DB has three colums: ItemCode, ItemName, Status. The Itemcode field is a combobox complex binded (if this matters), the ItemName colum is a textbox. How can I have the ItemName colum auto insert the text for the ItemName colum when I select the associated ItemCode with the combo box. I'm pretty sure I need to use the "CellValueChanged" event. I'm thinking an IF Then statement with 'e' parameter and colum and row indexes just not sure how to address it.
i would like to ask some help regarding combobox and textbox. so here's the problem, i've been trying to figure out how to assign a value into the textbox using the combobox and here's what it looks like [code]what i want to happen is that when i choose "Nursery" "1000" would automatically appear in the textbox.
I have this code inside am event in a combobox. Because I don't know the placement off the textbox before I have run the code in the combobox: Dim txttotal As TextBox txttotal = New TextBox txttotal.Name = "txttotal" txttotal.Location = New System.Drawing.Point(x4, y) txttotal.Size = New System.Drawing.Size(100, 15) txttotal.TextAlign = HorizontalAlignment.Right Me.TabPage3.Controls.Add(txttotal) I can see the textbox thats works fine. But in another event I will give txttotal a value But get the error txttotal not declared.
I want to populate the textboxs with the access databse fields when i select the combobox.
my combobox is populating but my txtunivdetails is not being populated. I am not able to find my error.
Private Sub UiComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged On Error Resume Next
