I have a chechedlistbox on my form in a windows project, and want to populate the checkedlist box with data that I querry from a table in sql database. I have the code below for the Form load event, but the checkedlistbox is not populated.
[Code]...
I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.
i want to know how to view data table in checkedlistbox and view selected record in another form.
View 2 RepliesI have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:
-1 form
-3 textboxes - textbox1, textbox2, textbox3
-1 label - label1
-1 combobox - combobox1
-5 buttons - button1, button2, button3, button4, button 5
the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..
I Have a problem with trying to get a checkedlistbox to work the way i want it to... Here are the 3 tables that i'm using. The links are shown in colour.
[Code]...
I have a checkedlistbox in a windows form: A Name textbox is linked to The Name in the Usertable
1.The DisplayMember in the checkedlistbox in the Area (Text) from the AreaID Table. This bit Works.
[Code]...
2.The ValueMember need to be the AreaID from the UserAreaTable
I need to do it this way because it allows me to add multiple areas to users, and add new area's without having to change the forms.
I'm working in VB 2008 Express.
I have an MS Access DB with a Table setup with the columns that I need.
I have it linked into a form, with the requisite BindingSource, TableAdapter, BindingNavigator, etc.
On the form, I also have several textboxes linked back to the table. I can populate the table via the + (add new) button in the BindingNavigator and then filling in the textboxes (and saving of course).
Is there a way that I can put a button on the form and populate the table automatically? I want to do this via a textbox to control the number of records added - that way, I can put in an 8 and have 8 blank records added to the table via this one click (and don't have to enter the default info in for the 8 records one at a time).
I've attempted to do this by calling the BindingNavigatorAddNewItem_Click subroutine, filling in the textboxes and then calling MapBindingNavigatorSaveItem_Click subroutine, but this does not work.
I am working on Visual Studio 2005, VB.At the back end,there is a table called "Marks" which has a column called "Subject". This column contains duplicate values.when the form loads,I want to display all the distinct values from the "Subject" column in the listbox.
View 2 RepliesI'm having some problems trying to input records into a relational database. The design is really simple but I'm running into a wall when it comes to having the foreign key from my child table autopopulate the primary key from the parent table. I've made the connections in Access and from what I understood, so long as I committed a transaction, the child table would populate the primary key from the parent table. This is not happening.
my question is: is there a method that would do what I'm looking for? or am I cornered into using @@IDENTITY and manually inserting the primary key into the child table?
I've tried using datasets and data adapters and created a datarelation within the dataset, but it is still not doing what I need. everything I've tried thus far has allowed me to insert records into multiple tables, but won't relate them because of the missing primary key in the child table.
I have 2 queries. One is populating a dataset that populates the dropdownlist and the other populates rest of the textboxes of a table row. i want to know how can i fill the entire dropdownlist and then make selectedvalue the value from the other query? e.g -
dataset query = select hobby from hobbies
other query - select name, dob, address, hobby from employee
now the table looks like this -
Name DOB Address Hobby
Sam 01/10/1988 111 main st Dropdownlist(n number of records)
Now in the dropdownlist I want all the hobbies populated with the hobby in the employee table to be the selected value.
I am trying to populate an Access table with data from a csv file. Here is my code
csvConn.Open()
Dim objAdapter As New OleDb.OleDbDataAdapter

The csv has 58 rows of data. The Access table I get is 58 rows of the same data as the first row of the csv. Am I not using parameters correctly?

View 7 Replieshow do i add columns to a listbox??
And Checkedlistbox add and edit more than 1 data per item. So if you take a look at Cheat engine it got 3 data per row. 1: the checkbox, 2: the item name and 3 the value i want to change if i doubleclick (all this in same row)
So if you take a look at A cheat engine Video at you tube you can see the checked listbox that you can freeze things and change values so more thann 1 data.
I am using VB 2010 express and am trying to make a program for a project that generates lottery numbers in a specific way. What I have is two forms. Form one has two text boxes and a button. Form two has a checkedlistbox that is pre-populated with numbers from 1-56. What I am trying to do is have the program open to form1, the user presses button1 ("Select Numbers") which opens form2. From there they will select numbers they want to pick from (narrowing their pool of lotto picks to only numbers they want to use). Then when they hit select, I want the numbers they have checked to return back to the textbox1 on form1. HOWEVER, I also only want 5 numbers, randomly selected, from the pool of checked numbers the user selected on form2 to return to the textbox1 on form1..... I may be in wayyy over my head, but I have all of the forms designed and I have been close to getting the forms to at least communicate, but still far from doing what I have described I am trying to do.

Can someone help me with this code?

View 2 Replies[VB 2008]. I'm trying to populate a DataGridView based on information in the Items in a ListBox (specifically, the file names without hypens or file extensions) and the content of the actual files. The DataGridView is supposed to look something like this:
IDNon-Hyphenated File NameFile Data
1. Some fileThe sky is blue.
2. Another fileThe grass is green.
The Items in the ListBox (lstFiles) look like this:
C:UsersUsernameDesktopFolderAsome-file.txt
C:UsersUsernameDesktopFolderAanother-file.txt
What is happening is that the DataGridView is being populated, but it looks like this:
IDNon-Hyphenated File NameFile Data
1 Another fileThe grass is green.
2 Another fileThe grass is green.
It's adding the second file's information to the DataTable twice and not adding the first file's information at all.
Private Sub btnDoSomething_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDoSomething.Click

tried quite a bit of iterations, not a local admin so i dont want to even bother using the data connection wizard, want to do all of this with unbound controls only the harder way for learning purposes and also so i dont have to keep logging in as local admin and create data sources in the future.

So another first timer question.I have user entered data from a form that gets put into separate strings. On another form i want this data to populate a Tree view when the user presses a button "Add data". There will be only one stage of parents and child. oParent and oChild. The oParent string will only have like 5 items but the oChild will have like 30 and these will be repeated for each oParent. Not sure how populate this, i cam guessing with some sort of For Each i in oParent, add i or whatever, but not sure of the syntax.
