View 8 RepliesI'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

View 2 RepliesWell currently I'm needing to store various settings, strings, integers, items, etc, within the program settings. So far this has gone without a snag and is working as planned except for one thing, Comboboxes. I have browsed through the various types of settings I can save to and the closest is a "System.Collection.Specialized.StringCollection", however VB is throwing up an error saying that:
Quote:
Error1Value of type 'System.Windows.Forms.ComboBox.ObjectCollection' cannot be converted to 'System.Collections.Specialized.StringCollection'.C:UsersUserAppDataLocalTemporary ProjectsProjectForm1.vb1234Project
How would I go about saving the items in a Combobox?

me.combobox1.SaveSettings()
or
me.nudResultsToShow.Settings.Save()

View 4 RepliesI am having issues when trying to populate a combobox that is dependent on another combobox. Populating the first combobox works as expected but attempting to set the value member or display member properties of the first combo box cause its selected index changed event to fire. That event seems to fire before the first combobox is fully loaded. The issue is then raised when trying to populate the second combo box, since it is dependent on having a valid value member to complete the dynamic sql statement, and at that point in time, there is no value member.
I can�t imagine that this is difficult but searching hasn�t yielded me any results. Should I be using a different event? What is the right way to do this?
I have a simple workaround in place - not allowing the second combo box to attempt to populate unless the first combobox has an index greater than zero but this hack is no good since it clearly prevents the user from selecting the first element in the first combo box.

I have added a textbox and a combobox into the form. There are 2 buttons as Add and Remove. Everything works fine here but the problem is after addig/removing (using add/remove button) new items into the combobox, when I close it, the new items added/removed are gone. I need to save the new items added to the combobox during close. I can understand I have to create a Application Setting which will save the new items added to combobox upon closing. But I don't know which code I need to use? Below are the currently used code of this project.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' This is to add new items to combobox
ComboBox1.Items.Add(TextBox1.Text)
'MsgBox("" & TextBox1.Text & " Successfully Added to Combobox")

What i'm attempting to do is have several textboxes where the user input's there information and a seperate text box to give there input a name so it can be sent to a combobox and saved with my.settings so when the program loads or the user needs the textboxes populating they can select the name in the combobox and it fill out the textboxes.

Which is not it, the method i used only involved a few clicks per item to set up and it made it so what ever selection was chosen in a combobox for example was saved, and then that selection was loaded on the apps next run, i know i had to do something in the application setting/databinding area of the properties.
I have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.
This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure

De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.
That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?
I'm trying to do the following: Store items from ComboBox in My.Settings (datatype doesn't matter). Retrieve these items to populate a ComboBox on formload. Also display these items (1 item per line) in TextBox, where I can edit and save the edits to both My.Settings and the ComboBox.

I have a program that reads a database file(.csv or.Txt) then allows user to select data from 6 different comboxes and taext boxes are then populated based on the selection made from combobox
I would like to be able to give the user the option to save their settings so next time the program is open it will connect to the same database as the last connection and also have comboboxes go to the last selection Do I have to create a save setting value for each combobox? and the connection string?
is there a simple way to just save everything? so when the program is open it goes back to the last time it was open.

I have created my first ComboBox form but now I am stumped. I am using VB Express 2010. What Toolbox or Property buttons do I use to generate code for the following:
(1) Title.Text (to add text on my form)
(2) Title. Location (location on the form)
(3) Items.ADD (to add the options on the drop down)
(4) Dropdownstyle
Please give instruction like On ToolBox (left side) click XXXXXX , then click, then click.
I am using a form with a combobox which is populated from an SQL database table. This works OK but is it possible to leave the box blank on the form until a value is selected.By default the box has the content of the first record.
