I am using oracle and trying to create a datagridview but when i try to create the dataset i get the error "could not retrieve schema information for table or view" stating my database and table name. I am using the Oracle client not the OLEDB as i have always used that and had no problems. I am using Oracle 11g.
View 6 RepliesI am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.
View 1 RepliesI have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.Here's the code I've written that successfully imports the data and displays the first column:

Im trying to use a CheckboxList Control to Store Yes and No and i noted there its a property on the control
"Selection Mode" One/MultiSelect/MultiSelect Extended
i set One expecting it to allow only one item being select at the same time but it doesnt work as expected, my question is there its another property to achieve this without having to code the event?.
i could do it by coding the event but, im tired of coding stuff that really isnt needed, since there are routines for that on VB.NET.

View 1 RepliesPretty basic question, I have a checkboxlist inside of a wizard control. I need to collect the value of all items that are checked, as well as whatever value is inside of a textbox if "other" is checked, to insert into my database during the Wizard.FinishButtonClick event. How do I do this?
View 1 RepliesSo, I'm running VB.net 3.5. I have a dynamic list of server names, and I want to put them in a CheckBoxList. The list is populated and, using that same list, I make a graph of the performance for each server listed. I want to be able to check and uncheck the checkboxes representing servers and, when I lick an update button, it'll create a new graph and graph only the servers that are still checked. I noticed that the page still loads before the button click is handled, so the CheckBoxList will repopulate itself before being able to read the current CheckBoxList. This is my load. And I populate my checkboxlist inside ShowView()
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Me.IsPostBack Then
[Code]....
And I wanna try to preserve the checkboxlist values when I do an event handler for an update button.
Private Sub btnUpdateGraph_Click(sender As Object, e As System.EventArgs) Handles btnUpdateGraph.Click
'insert code
End Sub
How do I specify that I want two columns on a checkboxlist?Below is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim di As New IO.DirectoryInfo("\bk00app0001Images")
Dim imageArray As IO.FileInfo() = di.GetFiles()
[code]....
how can i connect a checkboxlist with a database?
View 5 RepliesI have a list of options on my site that a user can select. What I want to do is provide functionality to limit the amount of content the user gets based on his selection in a CheckBoxList. Once he's selected what he wants, he'll click Save and his selection will be written to the database. The CheckBoxList is initially populated from the Modules table. This provides a list of modules that the user can select. When he clicks Save, the code needs to loop through this CheckBoxList and "pick out" the values for the CheckBoxes that were checked, disregarding the ones that weren't. The problem is that whether a CheckBox is checked or not, the debugger returns a False value for the CheckBoxList.Items(i).Selected property.
Here's my code:
Private Sub AddUpdateOrg(ByVal OrganizationName As String,
ByVal Action As String, Optional
ByVal Target As Integer = Nothing)
[Code] .....
Its possible that this behavior is the result of a postback from the save button. Upon further examination of the code, I've reconsidered the possibility that this issue is caused by a postback as the CheckBoxList is not bound on page load.
My below code pulls in 100 items into the checkboxlist all into one column. How can I modify the code so it will appear as two columns?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim di As New IO.DirectoryInfo(ImagePath)
Dim imageArray As IO.FileInfo() = di.GetFiles()
Dim image As IO.FileInfo
'list the names of all images in the specified directory
For Each image In imageArray.OrderBy(Function(i) i.Name)
CheckBoxList1.Items.Add(image.Name)
Next
End If
End Sub

View 1 RepliesI have a checkboxlist that is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a checkboxlist before so I'm not really sure how to go about this. Here is what I have tried so far:
[Code]...
When I re-display the array into the checkboxlist it shows that nothing was removed from the array.
I want to be able to show on the form1, the count of the number of items selected in a list. So if I tick one the number goes up, if I tick it down, the number goes down.
Checkboxlist is lstTAGs

How filter a array of checked value from vb net checkBoxList. Meaning List Of Selected group to be filtered using Query
View 9 RepliesEssentially, what I'm trying to do is get a list of values out of a database and put them into a bunch of checkboxes. When the user submits their selection of these checkboxes, I need to see what they've chosen.So I have no idea how many checkboxes I'll need, or what the values will be. I will however be listing different categories. I would like the final result to look something like this:
<h1>category 1</h1>
<input type="checkbox" name="cat1" value="avalue">
<input type="checkbox" name="cat1" value="anothervalue">
[code].....
However, I found this seemes to only work in the front end. I need these values passed back to the backend so I can decide what to do with them.
I have a checkboxlist which gets the data from XML file. If a user selects an item on checkboxlist, i just want to show that item and hide everything else. And beneath that, I want to add clickable text to let the use to choose something else. So if the use click on that text, the user will see the checkboxlist again with the first item selected.
Basically look like this. So how do we achieve this?
require to use vb.net/and checkboxlist control as we will be databinding dynamically from database.
