Pulls Data From Access And Loads It Into Textboxes And Comboboxes?
May 17, 2010
I have an edit Contact Form that pulls data from access and loads it into textboxes and comboboxes. The text is working fine, but I am trying to pull a number from the ddatabase and display that value in a combobox that already has selections in it, so the user can edit it. For example the combo box is filled with 1,000,000 - 60,000,000 and if the number in the database is 2,000,000 I wan the combobox to display 2,000,000 Here is the
[Code]...
I have tried selectedtext, selectedvalue, and selecteditem but none of them work because its a number.

How would you add data source to your combobox from a combobox that is connected to the access atabase?they are both ın the same form of course and the software language ıs Visual Basic. I ve got two comboboxes that I need to connect with eachother combobox1 is showing the "itemsonsell" from the "table_items" table from my access database, the second one should show the "prices" value from "table_items" depending on which "itemsonsell" item is chosen on combobox1,I ve done the solution below,but it didnt seem to be working,it is showing all the "prices" that are under the "table_items" table's "prices" class.

I'm using VB 2005 and have an Edit - Entry form with Textboxes and several Comboboxes. I populate the Comboboxes with Arraylists as shown below. I populate a datatable with the Employee data from my SQL Server. I assign the BindingSource1.Datasource to my Datatable then add Databindings to the ComboControls. The (Fields.STAFF_MGR_ID.ToString) is from an Enum. When all is complete my textbox fields Bind and move with the MoveNext.. no problem, but the comboboxes display nothing.

I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried
txtDate = ""
and
txtDate = Nothing
but an error comes up.

I am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs
Private Sub searchTab_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles searchTab.SelectedIndexChanged
searchTab.TabPages(searchTab.TabPages.IndexOf(searchTab.SelectedTab)).Controls.Add(splitContainer1)

I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:

this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I have a DataSet with a DataTable that has several numeric columns of Data. The numeric data is composed of distances given in U.S. Standard units. I currently have my ComboBoxes set up and working, but I need to expand on what I currently have in two ways.I need to be able to convert the Decimal numbers in my data column being displayed to Fractions, is there a way to do this and maintain databinding? In this case its the Display Member of the data source...I need to be able to display my drop down options in different sets of units... I've written Unit Conversion classes to help take care of this, but I don't know if I can somehow do this as well and maintain databinding? I'd like to convert the units on the display members as well...
Private Sub ComboBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ComboBox1.SelectionChangeCommitted
Select Case ComboBox1.SelectedItem

What is the best approach for using ComboBoxes when dealing with issues such as displaying fractions and units...

I have a very useful vb6 program that reads ms access tables and loads the data onto a sql server database in the correct format. The customer maintains his data using the access tables. The vb6 program allows him to then select the data categories he wants and loads the data onto a sql server database online.I haven't used vb.net yet.

I've run into a bit of a roadblock trying to figure out how to programmatically not allow the same data in multiple comboboxes. I'm usnig VS2008 and I have 3 comboboxes on a form, all with the same data, say "apple", "orange", and "red". The comboboxes are nothing more than a user definable sorting method on which gets calculated first. When I use the .SelectedItemChanged event on any of these, I'll obviously be duplicating. Any idea on how I can program to automatically switch the combobox that is duplicated to the value that is missing? I don't want to hard code it as further down the road I will have up to 7 comboboxes. Below is what I started with coding. Not sure if it is the best way to go about it, but it works on 4 of the 6 combinations.

I am having difficulty trying to fill two different comboboxes (cbo) with data from a database. More accurately, the 1st cbo gets filled correctly, but when I attempt to do something similar with the second, I'm getting an error about not being able to use the & Operator in my SQL string (Operator is not defined for string and DataRowView types). So evidently the SelectValue from my combobox isn't acting the way I expect.
The overall goal of what I am attempting to do is to fill two cbo's, one with a list of contracts and a second as a list of parts given the selected contract from the first cbo. There are 3 tables in the database that I am drawing the data from: the "contract" table, the "parts" table, and a bridge table called "partList" that has foreign keys pointing to the two other tables. The first cbo is a basic query to the "contract" table using "ContractName" as the display member and "idContract" as the value member. The 2nd cbo I would like to display the name of the part from the "parts" table but use the id of the part from the "partsList" table, and to further filter this list based on what contract was selected.
I am writing the code in VB.Net from VS 2010, storing the data in a MySQL DB, and using a DBFactory to create all the components from ".GetFactory(MySql.Data.MySqlClient)"Below is the code that has the two places I am attempting to fill the two cbo's. Also if there is a better way to handle this, please let me know.

I have a basic page which has fields that I read from the database and write to it. I would like to know where I should call the insert and read commands. I know about age_load but heard about page_loadcomplete.I noted that when the user refreshes the page, for some reason the sqldatasource loads the old data(before the write) even though new data has been loaded on the form.

I have a class that pulls the ID3 information from an MP3 file. This information is at the very end of the file in plain ASCII. The original author is using FileGet to retrieve just the last 127 characters of each mp3 file. The issue is that this information is put into strings declared like this...
Public strTag As New String(" ", 3)
Public strTitle As New String(" ", 30)
Public strArtist As New String(" ", 30)
[CODE]...
This part all works fine. But I'm trying to code a property that returns a string like this...
return strTitle & " - " & strArtist
But for some odd reason it is being very strict about the length of the returned string. It usually just returns the strTitle, and not the " - " or strArtist, and if I switch the positions, it will just return strArtist. So obviously both Strings have information in them.
I'm an intermediate programmer, but just breaking into VB.NET. I'm not sure what the New String(" ",30) part does, but it is definitely interfering with the string concatenation that I'm trying to return. Anyone ever had a similar issue?
I've tried String.Copy, String.Concat, etc. I've also tried doing ReadtoEnd(), but it takes forever for just 10 mp3 files, so I can't imagine how long it would take with a whole library. The only thing that slightly works is if I do... return strTitle.SubString(0,5) & " - " & strArtist.SubString(0,5)
But like I said, coincidentally it will only return around 30 characters.

I have one table here with a list of UserIDs, Users, and ClientCodes.Each user can be assigned a client code to view that client's data else where.Right now I have to change it for everyone via SQL Server and actually going into the table manually, but I'm trying to make a simple little program that will let the user change it themselves.All I need is a textbox that pulls the user based on a certain UserID from the table, and a drop down list that will not only show the current ClientCode they're set to, but allow me to change it and save that change to the table in the database.What's the best way to go about this? I tried using the wizards but I guess that's not the best way to go about it.I have it displaying the correct user and their current ClientCode but that's about it.
