In a windows forms project, I have several combo boxes. The first combo box contains a list of objects. Those objects then have several lists which are used as the datasource's for the successive combo boxes, depending on which item is chosen in the first.
[Code]...
I have a single table that has (3) Fields displayed in their own combo boxes. Right now they can only be sorted by one set of criteria. Unfortunately that leaves the other (2) Combo Boxes in random order. When "One" of the values, in "One" of the combo boxes is updated, ALL 3 of them jump to the same record and display the correct data. This part works as designed.The problem is, I need to have a way to sort the other (2) Combo box's data, which is also populated from the same table, AT THE SAME TIME, so that all (3) present sorted data in each of the (3) Combo Boxes. Then when one of the combo boxes is updated, ALL (3) will get updated, just like they do now.THis data populates three of the cells in a data grid, and then the underlyting table(s) after saving. Like I said, the (3) work, but only with one of the orders sorted. I need the same exact functionality, but with (3) different sort orders on the (3) Boxes.The (3) Combo Boxes are:
1.) cb_PlayerNumber - A Sorted list by the Player's Number (2 Digits as String)
2.) cb_Lastname - A Sorted List By player's Last Name (String)
3.) cb_FirstName - A Sorted List by the Player's First Name (String)
The table these three combo boxes is populated from is the "Players" Table. they all populate perspective colums in the "Gamedata" Datagrid, along with selected data from combo boxes populated from other tables which, when saved updates the "GameData" Table.
Add a new report to a windows forms project. Now add the table data region from the tools. If you don't already have a strongly typed dataset displayed in the data sources view, get that ready. Now do the tried and true easy-to-use trick of dragging a field from data sources onto the table's details row.

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
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.

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 have inherited from a Windows.Forms.Listbox so I could override the OnPaint and OnDrawItem methods in an effort to highlight specific items and alternate backcolors. I am also skipping some DrawItem events to prevent flickering.Everything is working fine, however when I select items in the listbox, it looks like the font is shrinking or becoming more compressed.Then when I mouse leave, the font goes back to its normal size and appearance but the same items are still selected (which is correct). During debugging the font never changes nor do any of its properties, but it does end up looking different when the item is selected and the mousedown event just happened.

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

What are the best practices to develop a software in such a way that I can release updates, I mean I can release an update which replace the existing executable but in case I have added some new references (dlls) to the project this won't work ? Is there any way I can do it without running an MSI?

View 3 RepliesI have created an application which uses an sql server connection as its datasource. The problem I'm having is that the application needs to work on computer that has no network connection. How Can i change the datasource so that on runtime it can work off a machine that is not connected to a network? The datasource from the sql connection only contains one table with no data. It only needs to be updated with a target folder that can be changed to any location on any computer already written in the code.
The connection string suddenly stands as: Dim MyConnectionString As String = "Data Source=MY-PC;Initial Catalog=ImageLocs;User Id=test;Password=test;Pooling=False"

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.

I was having a heck of a time populating a gridview combo box.I learned a ton in the last 48 hours but would really like to know the answers to the bottom three questions.You guys are the experts, so I'm hoping you will enlighten meBut the summary of it is below:I was never able to get the ComboBox to bind to the data source. I tried everything until I turned blue. So I went to the basics and coded all the automatic stuff. I'm curious as to why the automatic binding didn't work. Perhaps its because my gridview datasource was LINQ.Here is how I pulled it off. I hope someone down the road benefits from the last 48 hours of my delima:First of all, know that I have two drop down lists on my form, one is the GPField and the other is the BankField. These are already populated DDLs that are static. So I used them to cheat on the values instead of using enums.
Sub fillGPFieldListDDL(ByVal obj As Object)
Dim db As New CompanyDataDataContext
Dim myConn As New Connection With {.ConnCls = ConnCls}

i am using a couple bound comboboxes in a bound datagridview. It seems though, when the combo's are changed, and the tableadapter is filled again, the changes are not being saved to the table. Is there a special trick to getting the data in the combo boxes to saved when the values are changed?
View 4 RepliesI have two combo boxes: cboRepairCategory (plumbing, landscaping, etc) and cboVendors. I am using Stored Procedures in SQL to store the data from my database and then load them into the combo boxes.The cboRepairCategory will be loaded first. Once the user has selected what type of repair it is I want it to restrict the amount of vendors that can be selected, so instead of saying:CREATE PROCEDURE dbo.up_Fill_Vendor_Combo
AS
SELECT VendorID, CompanyName
FROM Vendors
[code].....
I would select only the vendors that have the RepairType of say Landscaping, so thecboVendor would load now only Vendors with Landscaping instead of all vendors.My question is this: Is this done in SQL in my Stored Procedure or is it done in VB in my functions for my combo boxes. I've never tried this before I am totally lost on it. I have fiddled with the code on both ends but to no avail.
im trying to learn how to code more efficiently and was wondering how to preload combo boxes better. im working on a project atm that has many comboboxes with the same menu information. how to i link the information in a sub procedure when the comboboxes all have different names?
