I have a form that has some combo boxes in it, and a table in SQL Server that stores the Values for the selected item for the combo box.I have read the data out from the combo box and inserted it into the SQL table as a integer. Now I want to read it back in to the form.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I choose one record from combo box... that is bind from name after that when i select another it gives error
I was wondering whether it's possible to change the highlight colour for a combo box without having to create a custom control? Just to try and make what I'm asking clearer, it's not the ForeColour or the BackColour that I'm wanting to change but the colour that's shown by the mouse when you move it over the combo box items.
View 8 RepliesI have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

im trying to pick up Visual basic on my own with no friends/family that have any programming experience.. I'm struggling (surprise surprise)Heres what I'm trying to do...I have 1 combo box, It will list product names.. Lets say 15 of them.. (I know 15 i could just as easily specify them individually within VB.. but lets assume I NEED to read them from an excel file.(Excel 2003)
Part 1 :Really all i need to know for now, is how do I load an excel worksheet into VB so I can call data up from the cells / rows / columns..
Part 2 : How do I define Which Cells from Each row or column I want to populate into the combo box... Presuming for the "Product name" combobox I have placed each of the 15 product names in the excel file under Row 1, column A through Row 15 , Column A.I want to avoid this and just call the xls file into VB. (Excel will be installed on any computer running this application if that matters. )

View 1 RepliesI have two buttons: show button and next button. I want the show button to show the first result and then for every click of the next button, I want to go the the next result. I did this code for the show button:
cmd.Parameters.AddWithValue("@sex", TextBox4.Text)
dr = cmd.ExecuteScalar
If dr.HasRows Then
While (dr.Read)
TextBox1.Text = dr(0)

Now the number of rows returned is 5. But on clicking the show button I can see only the last row in the textbox's. Then how to see the first row by clicking the show button? And how to see all rows one after another by clicking the next button? I need to use:
dr.NextResult()
to loop through the fetched data. But I cant place it properly in the next button code. How to do the code for show and next button to get the desired result?

View 4 RepliesI am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.

View 3 RepliesI am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.
