I have a small requirement and that is as follows: I am calling a stored procedure and based on the results from the stored procedure, i want to display the data into textboxes. I am using DataSet and DataAdapter for the same. Can anyone help me. My code is as follows:
Dim sqlStripCmd As New SqlCommand("prcAdt_mwo_strip_det_sel", connection.conn)
sqlStripCmd.CommandType = CommandType.StoredProcedure
sqlStripCmd.Parameters.Add("@strip_no", SqlDbType.Char, 3).Value = txtMwoStpNo.Text

I am getting the data and am able to display it into a datagrid, but how do i put it into textboxes.
how to go about populating some text boxes with results from calculations. To be more specific, I'm trying to do some trig to calculate various parts of a ci0rcle and will be populating any two of the text boxes then click on a button to get the missing values. I was thinking along the lines of a loop until all values have been calculated.
View 14 RepliesI am building a form in access database.
I have a combo box which is linked to a query which is looking up a unique reference number from a table called Tbl_Submitted_Requests.
What I need the form to do is auto populate the other text boxes when the user selects the unique reference from the combo box. How can I get the text boxes to auto populate with the data that is associated with each unique reference?
I am using the following code for populating the combo boxes in my application. It is really nice. If any one requires, may use this. It takes three parameters. The first, the name of the Combo Box and the second, the SQL Statement to populate the combo box and the third is the number of column to be displayed (from the SQL statement)

I'm familiar with Visual C# and the try/catch for that but I cannot seem to figure out how to do the same thing in VB. Basically I can't figure out how to get the try/catch to work with text boxes and input from the user and whatnot.I've tried setting the textbox.text property = "" but that has no use, I've been trying to find something on Google about it but I cannot seem to find a single thing about textbox try/catch statements. Is it possible to do it with text boxes?
View 5 Repliesthe project here is to take the three amounts from three text boxes entered by the user and return a string in a label telling the user if the triangle is either a right triangle, equilateral triangle, or neither after clicking a button. The code I have must use a new Class named Triangle. No matter what is entered in the text boxes, the label always returns "You created a right triangle!"

I use vb.net express 2010. I have tried to find a way to add an EULA to my project but have not found it (nor any solutions online).
does express have the ability to add an EULA?also is there a way to get the setup file to move the database into a particular area OR have it make a new database where the user selects?
I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:
Public Class Form1
Private MouseIsDown As Boolean = False
'rivate Functionlist As ListBox

I am creating the items in a combobox in my code behind. I am setting the display member and the value member. When the user makes a selection from the combo box, I need to get the value of the selected item. I have written some code, but when I step through it, it says that the selectedvalue is Nothing.
Here is the code where I am creating the items in the combo box:
Do While drReader.Read
cboTheater.Items.Add(drReader("TheaterDesc"))
cboTheater.ValueMember = CStr(drReader("TheaterID"))
cboTheater.DisplayMember = CStr(drReader("TheaterDesc"))
Loop
In the selected index change event for the combo box, I am doing the following:
Dim strTheater As String
strTheater = CStr(cboTheater.SelectedValue)
When I step thru the code, strTheater is Nothing
I have a form on which the user selects a file using an openFileDialog. The selected filepath is then processed, which may take 10-20 seconds before the user is presented with the results.I'm finding that the once the user selects the file (clicking the OK button on the openFileDialog), the openFileDialog remains open until all of the processing going on in the background is completed. Once the processing has finished the openFileDialog disappears and the results are shown.The problem is that whilst the openFileDialog remains open on screen, it is not apparent to the user that anything is happening in the background. I do actually have a textbox which updates the user with messages showing the progress. However the openFileDialog hides the messages until it closes, essentially making the progress messages useless.What I'm trying to do is have the openFileDialog close immediately that the user selects a file. Then the processing can continue without the openFileDialog obscuring my form.

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?

View 14 RepliesI have a simple web for that has a dropdown list and a button on the form.The dropdown list is bound to a table in my database and holds three values with idents between 1 and 3 (Weekly,Monthly, Please Select).I have set my datasource to pull back item 3 (Please Select) as the first item in the dropdown list to prompt the user to select an option. Items 1 & 2 have data assigned to them and this pulls back the relevent data for these options.
Here is my problem. I need to hide my button when the page loads until the user selects item 1 or 2 and would like the button to be hidden of option 3 is selected. I have tried to complete this in my page load event and the code for the dropdown list but i cannot seem to get this to work.
If IsNumeric(DropDownList1.SelectedValue) = 3 Then
btnAddAgendaTemplate.Visible = False

I'm trying to create a for loop that will display the values (favorite programming languages) a user selects for a listbox.
So far I have this:
Dim selectedLanguages As String = ""
For intLoopIndex As Integer = 0 To languageListBox.Items.Count - 1
[code]....
So far, no matter how many items they select it will display a comma even if only one item is selected, example "C#,"However this is what I need it to do:
1. If the user selects one programming language than it should just printout the selected course with a period right after it. Example: C#.
2. If the user selects two languages it needs to have the text "and" between them followed by a period. Example: VisualBasic.Net and C#.
3. If the user selects three or more languages it needs to seperate them like this for example (again with a period at the end): VisualBasic.Net, C#, and Asp.net.
