VS 2005 Getting Information From DataSet To Populate Defaults In Controls?
Jan 27, 2011
I have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.
This is my stored procedure. It is called sp_GetClientInfoByName.
vb
CREATE PROCEDURE sp_GetClientInfoByName
I'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft Visual Studio, 2008, Microsoft Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.
I'm a bigginer in Visual Studio. I have created the forms using Visual Studio Professional 2005 and a database using Microsoft SQL Server 2005. I have some combo boxes in the forms and want to populate them using the dataset which I have attached to the VB.net project. I used the following method.. but when I run the project, the combo box is still empty..
I am receiving information via a serial port as Integers. The information is the displayed on textboxes(two text boxes). My problem is that, I am failing to transfer this information to a Datagridview.I have written the following code.
Private Sub BtnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSave.Click TxtDuration.Clear()
Background - I'm trying to populate a drop down list with state information from a database. I'd like the full state name to be the option and the state abbreviation to be the value. Example:
<option value="AL">ALABAMA</option>
Current Progress - The full state names and abbreviations already exist in the DB. I've successfully populated the DDL with full state names from the DB. Here's the code I've used to do this (minus stuff I've deemed irrelevant).Model Context (generated from template):
Partial Public Class BrokerCRMEntities Public Property States() As DbSet(Of State) End Class State Model (generated from template): Partial Public Class State
[Code]...
Question - In addition to populating full state names like I've done above, I'd also like to populate the value of the select options in the same DDL with the state abbreviations in my DB/model. How is this done?
I am new to Visual Basic and I'm trying to make a simple combo box that automatically populates from dataset. The table is from BaseMaterial with the column Material.
I am trying to populate a dataset from an XML file. Within the xml file are some € signs. However, when the data is read from the XML, the € sign is displayed as a ?. Has anyone seen this behaviour before, and if so do you know how to correct this? Below is a copy of the code i use to read the data from the xml file:
Public Function ReadExportFile(ByVal sFilePath As String) As Boolean Try msExportFile = sFilePath
Is it possible to populate a listview with a dataset? I have a function that returns a dataset. Why im asking this is because my SQL is quite complicated and i can't convert it to a SQLDataSource..
I'm trying to populate an array from a dataset with only specific column using vb.net 2010. is there any code to populate the array directly or must i make the use of a query?
I'm trying to populate a combo box with a dataset, this sort of works, but everything is just appearing on the same line. I think this answer might be to put the dataset into an array, then put the array into the combo box.
...problem is, I'm not sure how to do this! My code thus far is,
Dim usernameList As Array 'Retrieve usernames where player has available status GetFilteredData()
My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:
Public Sub Connect() Dim cn As OleDbConnection Dim cmd As OleDbCommand Dim dr As OleDbDataReader
I have need for a database in my latest app, i quickly realised it had been a long time since i last used a database and am in fact very very rusty on the subject. So i decided to create a simple DataSet using the designer, i created 2 tables as follows
Table 1 is Named Map and contains a 2 dimensional array each cell containing an array of object id's of anything in that cell, and a level ID.
Table 2 contains data about these objects ie size weight and a z-order, again referenced by an object id (matching Table1)
This i did with no issues, when it came however to actually populating these tables i drew a blank. Do i have to locate the database file and edit with notepad? I presume not. Maybe i have to use an external app like sqlmanager? I seem to recall from my past that i added table rows from within the designer but i cannot find this in 2010 express
This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.
What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;
So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.
How do I loop through a dataset and populate a DataGridView - heres my code. Hopefully someone can point out where Im going wrong... Not getting a specific error, just failed message box. when i take out the try/catch function then Im given no error but the DataGridView does not populate.
I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.

I am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.
There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?
I am working in vb.net and i have a simple requirement. I have added a MDB file to a dataset and it contains 21 tables. I have a datagridview and a combobox on my form. I was able to get the combobox populated with the table names available in the dataset by iterating through dataset.tables. Now i want to add the feature where the user can select the table name from the combo and then it should populate the contents of that table. I tried the following Code
I have a listbox with a dataset and a query that is used to populate the listbox. Now, depending on the selection of the listbox. I want to populate a variety of labels with specific information from the dataset with the selected listbox item as the key. Here is the code I have so far... but I am unsure how to continue....
Public Class frmItemsToCal Private Sub frmItemsToCal_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'BISEMv2DataSet.Equipment' table. You can move, or remove it, as needed. Me.EquipmentTableAdapter.Fill(Me.BISEMv2DataSet.Equipment)
I do however have a slight background with VBA particularly with MS Access, so I am not completely lost.I am recreating my Access database application in VB.net.I created a new project and added an Access database through the wizard, which automatically created a dataset for the database. On one of my forms I have, esentially, a search form. What I want to happen is have a text box, and as I start typing display a search result from my customers table in the list box under it. So for example, I type "A" and all customer names that start with "A" are displayed in the list box.I continue typing with a "p" (full string is now "Ap"), then all customer names that start with "Ap" are displayed and so on...
I did search on my own first before posting this and found a few tips but cant really get it to work the way I want. This is what I have... I know I would put this code in the keypress event of my test box, but just until I get it working I attached it to a button to search. (I basically got this online and not even sure its the correct usage.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click 'Create a dataview[code].....
The item in red is where i get an error. it sucessfully builds and i open the find form enter a last name that I know is in the customers table, but I get the error "Cannot find Column ["whatever name i typed inthe text box"].So first of all is this the correct way of going about what I want to achieve?If so how can I get it to work?BTW the next step for the user would be to double click the customer in the list box they are searching for to open the customer Details form for that customer, so I would need an ID or Index attached to that item to be able to open that record in another form.
i have a Userform that I created in MS Word that automates almost half my job. I'm just looking to re-create this form in VB.Net so that I can keep up with the trends.What I did previously was load a listbox based on the contents of a data table in another word document. I've searched for other methods of creating a datasource in VB 2010 Express but I'm unsure how to load the contents of a dataset or datatable as opposed to a table from MS Word. Ideally, I'd like to abandon using Word tables and create a dataset in VB and load a listbox based on that. I do not have a copy of MS Access and I'm unfamiliar with MySql, which I'm guessing would are the easiest methods of loading a dataset. I also thought that maybe if I could create a seperate form (let's just call it form1) specifically for entering new data and saving the form as data is added, then linking the datasource from that form to a second form (form2) that has the listbox that will populate with the contents from the data in form1.
I am creating a custom design for printing (RDLC)Is this possible to populate my rdlc from pre populated Dataset?I am populating my dataset like this
Private Sub populateExam() Dim daClients As New SqlDataAdapter Dim dsClients As New DataSet
[code]....
My Dataset hold only 1 record from my database.I need to pass that record into my cutomize page for printing.This is my layout. the red rectangle is the place for the values.
I started a vb form project and tried to add a data adapter and dataset to the project. Using the "Add new data source" wizard,
I get the error: "Could not get type information for ...dataset" I have tested this with two dB's and get the same error each time. One was the master db and the other was a dB that is custom. The stored Proc's are very simple, the first I tried was
Select name from Sysdatabases;
The other was one that had worked in VS2003 in another project.
VS2005 Pro, VB project on Windows XP sp2, SQL 2000 sp4 on a windows 2003sp1 enterprise server.
So I have a form that uses a datagrid with checkbox selections for multiple (read as many!) items.When I click a button labeled "Save to file", all the information on the form, to include the values of the selected datagrid items are then saved to a database. It works great most of the time.However, I have found that if I select more than 3 items in the datagrid, I get an error pointing to the data set and data adapter stating "OleDbException was unhandled - The field is too small to accept the amount of data you attempted to add.Try inserting or pasting less data".The code it points to is:
da.update(ds, "TrainingRecords")
In the dataset, I have tried to change the max length of the associated field.It was set at 255, and as long as I stay under that, I seem to be fine. But if I go over it, I get the error. I can change the design I guess to make it less wordy and therefore store less data, but is there an easier way?
I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String) Try TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
