I'm trying to create a "LOTTO" number picker, but I don't want to have more than one TextBox. And I also don't want duplicates in that single textbox. The program randomly picks six numbers from 1 to 30 (Sorry I don't have the code at the moment).
My code runs fine, but I keep getting duplicates in the textbox. (I'll update as soon I have the code.)
I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
i used the following technique to Select multiple items from DropDownList into TextBox with No duplicates, however i dont think it is the most proper way,
pressing again with same value selected choose another value from DDL and press button
here is my code Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click If TextBox2.Text.Contains(DropDownList1.SelectedItem.Text) Then
Alright I have my assignment to the bottom, and my code so far in CODE mark up.I'm trying to get a value in a textbox assigned to a variable (Price) add to a variable (Subtotal), clear out the textbox and loop around. I looked for hours in my book and google and couldn't find m
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I just wanna ask if it is possible whenever i press the barcode it will just go in just a single textbox1 instead of having it with other textbox2 or other textboxes selected
I'd like to create a standard AutocompleteTextBox that works with a timer, such that there is only one BackgroundWorker working on searching - if the user entered a few more keystrokes, but the old search is still running - that search shall be canceled gracefuly (via CancelAsync), and as soon as its canceled the new search will begin.
I'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:
I have a rich textbox with words in it separated by space characters. I want to create a mouseover event so that when I drag the cursor over a single word in the rich textbox that the word wil be highlighted grey. How do I set up the mouse over event to trigger whilst hovering above this specific control and do I make it recognize a stand alone word,
I am working on getting a multiple values from a single column displayed in a single textbox or label. I know I should be able to find the information I need online, but I am coming up empty. I am using Visual Studio 2010 with SQL Server 2005. For example, I want to pull all the email addresses, that have a value, from a table and display them together. The output I am looking for is like this:
I am using this code to insert into a single table.How to use the code to insert the textbox text to multiple tables of same column on single button click event in VB.net?
Imports System.Data.SqlClient Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click Dim con As New SqlConnection
For rich textbox in vb.net i want to have single border line. Fixed single and Fixed 3D are having some dimensional effect which i do not want. And i would also like to change the color of the border.
And same thing with the button, for them how to have single line border and specified color.
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?
Say I have a code with 3 methods that do some pretty intensive work. Would executing these methods on 3 seperate threads be faster then executing them one after the other on a single core cpu? And what if it's a dual core or HT?
I use SqlParameters when executing database statements. I know that I can replace a single quote with two single quotes... but in the past SqlParameters took care of this for me. I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):
I am trying to update a row or a single cell in ms access through vb.net. But when i update the text box named NRIC, say for example i want to update "s4522147B" to "tr4521856C" and mean while leaving the other fields the same.
But the thing is when i make the changes in nric.text (textbox), the dataset actually updates the whole column in the table instead of the selected textbox.
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

Im using the following code to wrap html tags around text in a texbox and transfer the text to a single multiline textbox from form1 to form2.[code]My problem is that if for example textbox5 and textbox6 are empty i want the program to continue anyway.
I have a database running on SQL server primary key is all set, my question is i dont want to allow duplicates in the primary key, i want everything to be uniqure. The database already has information in it, is there a away to set it so when i add a new row through the table adapter that it will recognise the last primary key value and increment it by +1?
I have a problem with ensuring no duplicates. I have an Appointments form (frmAppointments) and within it exits 4 date time pickers. The first 2 date time pickers are dedicated to creating an appointment date whilst the other 2 are for the purpose of changing an existing appointment date. When the date and time is entered into either one of the pairs (of date time pickers), the values inside get transferred to 2 corresponding textboxes. The user then clicks Save (btnSave) and the values are saved to sql.
How can I ensure no duplicates (of the date and time) can be created?

i use csv file to populate my dgv. now i wanna eliminate duplicates from my dgv. i knew it could be done using unique datatable. but i wanna eliminate it from dgv not from the dataset or datatable.to understand it in better way- i wanna check column1 if the vales in column 1 are repeated then the entire row must be deleted i.e the duplicate row must be deleted( if column 1 has 2 duplicate values then 1 row must be deleted)
I'm reading and writing to an xml file and am looking for a way to identify and delete certain nodes. Below is an example depicting the data as rows with each row sequenced in "Sortorder". As you may note, "Sortorder=1" data is there twice.one row containing data... the other not. I'd like to keep the row containing data and delete the one that has blank data elements.
I have 2 files one is located at ("C:DNSREDIRlocked.txt") the other is ("C:DNSREDIRcustomb.txt"). What i'm trying to do is that i need to add the text found in customb.txt file to the last line in blocked.txt and remove any duplicates found in blocked.txt. [code]...
