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 two forms, forms a and b. Each form has a combo box. The user selects an item from form A's combo box and saves their selection to a database by pressing a button. How can I display their combo box selection from form A in form B's combo box on form B's form_load event?

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 a form with a DataGridView and ComboBox, both of which are populated with data from an Excel spreadsheet, the source is unbound. My problem is in repopulating the DataGridView with data from another worksheet in the same Excel file when the user selects the corresponding value from the ComboBox. For example if they were to select January from the ComboBox then the DataGridView would load in and display the data contained on say Sheet2, selecting February would load Sheet 3 and so on. I am running Visual Studio 2008.

I have developed a drawing tool that allows the user to add graphically referenced database records to a picturbox.While for testing purposes i was simply loading any picture into the picture box what i want is on selecting a building name from a combobox that it automatically populates the related floor levels (that apply to that building)to appear as a selection in a 2nd combobox. On selection of say 1st floor i want to load the relevant floor plan (JPEG)image into the picturebox.The tool i have developed has an estate builder function where you ccan build your estate profile i.e specify the buildings and floors etc and these are added to a database file. What i would like to do is at the same time specify the floor plan JPEG file location and for this to be stored in the database in a way which would enable me to load the image automaticaly when i select the floor level

I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles
Rock
4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.

This is the first time that I will have ever actually published a program and I have a question about when it goes into 'real use' Right now I have string variables that sets the values of a few text boxes that can be edited and 'saved' (the variable values change to the new input).
When I publish the program will these values be saved in the variables after the program is closed then re-opened? Or is everything reset when the program is restarted? And if it is all reset, is there anything internal (aka not a xml file or something) that will hold the data and keep the changes?

I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

I want to make it so you can type a name into an input box and have it go into your combobox1. Then also have it to where you can load a list of names into your combobox from a text file where the text in the text file would be like this
NAME 1
NAME 2
NAME 3
NAME 4
So it will enter in the combobox1 like that. Also, This is an account maker, So I was wondering how I would make it so after it creates the account it will use the next text, can I just use the "Next" method?

I would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.

I have a set of labels that contain number values that need to be saved into a txt file and recalled from a text file by a button click event.
Ive been searching these fourms for days trying to find the answer to the save / load data problem. From what I understand, XML should be used to do this. But no matter how much I read I cant make sense out of how to solve this issue. I just need a simple and quick fix that dosen't have to use XML[code]...

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range
Dim data, i As Long, j As Long
With Sheet1

Well 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?
