Save Multiple Times By Doing A LOOP Depending On The Number Of Checked Checkboxes On A Datagridview .NET 2010?
Oct 11, 2011
I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
Example: That's 8 different combinations: 1, X, 1 1, X, X 1, 2, 1 1, 2, X X, X, 1 X, X, X X, X, 1 X, 2, X
Any way to get the different combinations depending on the Checked checkboxes into an ArrayList. One entry per possible combination (like the example above). Note this example is just for 3 games, I will have 13 games in my program so if you click all checkboxes thats 1,6M combinations. Is it really wise to have 1,6M entries in an Array? I also want to be able to set demands, like: delete all lines in the Array containing two X. Maybe an ArrayList isn't the way to go?
I have a list of 100 assets that are pulled from AS400 and shown on a gridview alongside a dropdown box with 6 possible status and a textbox.
If the user selects a status other than "Found" (whether it's "Not Found", "Scrapped", "Sold", "Transferred","Other"), the user cannot leave the textbox empty. They must insert a comment into the textbox. Once the user is done he clicks "Save" and if, let's say, the status is "Sold" and the textbox is empty for all assets then a Message Box pops up saying "Please fill the textbox".
The problem is, the message box pops up 100 times (or once for every asset that has the error).
1) What can I do so that the message box only appears once even when 100 assets have the error?
2) Also, when the message box appears and I click "OK" the information the user had filled up to that point gets erased.

Suppose we got a form with some checkboxes. Each ckeckbox represents a method of the same class. Each method takes no arguments, returns no values. Is it possible using a delegate to loop through the checkboxes and run only the methods being checked?
I'm trying to loop through a column of checkboxes to see how many checked values there are in that column. The user has to have 2; no more, no less than 2, otherwise an error should show up.
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing Dim count As Integer = 0 Dim x As Integer = 0 For x = 1 To DataGridView1.RowCount - 1 [Code] ....
The error message still occurs when I have only 2 chosen in that column. I even tried this If CBool(DataGridView1.Rows(x).Cells(7).Value = Checkstate.checked) Then
I wanted to see if I could have a list of six check boxes with names of a certain author that people have or have not read. When they are asked to check all that apply to them and then hit submit I want a label to display a message depending on the number of checks they made. So if they have 2 checks marked off then a message could say, "You do not read much of this authors books?" or 5 could say " You like this author, don't you?".
i have 5 checkboxes..and then i want to save the checked checkboxes on the database..how is possible?say for example checkboxes 1 2 3 are checked..how can i put them in the databse?i am using my sql..
I'm trying to count the number of checked checkboxes in column 5 of the table. I've tried several approaches, but none have worked so far.This is the code I've written so far. As you can see, I've managed to count the number of rows.

I have four textboxes that only accepts numeric data.On each box is a corresponding checkbox.I want to have a button that will get the total sum of all textboxes wherein their checkboxes are on checked state.
i have this code for saving my DGV as a comma separated text file:[code]It saves fine, but where checkboxes are unchecked, or "false" in the text file, these show as blank columns which then throw errors when i reopen the text file into the datagridview.how can i get my code to save checkboxes which are not checked as a "false" value.

I read the lines from a textfile into a string array and then I use a foreach loop on the string array. I want to go through the same string array again after the loop reach the end of the string array
as a starter project I am trying to create a list of checkboxes with the text as takeaway menu dishes & have labels assigned beside them containing the prices. if some of the checkboxes are checked I would like the total of the prices in the corresponding labels to appear in a text box & the dishes on the checkbox text to appear in a message box. I've managed to code my messagebox output but can't seem to figure out how to add up the selected labels.Here is my code so far, could someone please suggest a way of achieving what i'm trying to do.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim dishes As String = ""
I'm trying to loop the inputbox 5 times but I'm not sure how. Dim payroll1 As String payroll1 = InputBox("What is the payrolls for store1", "Inc", , , ) Lblstore1.Text = payroll1 I can get it to loop till a specific amount but not 5 times exactly.
I have a datagridview created for my windows app in 2005 and I'm not sure how to get it to grow and shrink, depending on the number of rows that are displayed. The form contains several filters for the user to use in order to get their desired recordset displayed in the grid and therefore, the size of the grid will be constantly changing. How is this usually handled?
I would like to know if there was a way to loop through all the checkboxes on a form and if the checkbox is checked then I need it to copy the text from the checkbox and the label. Thera are 23 of these labels with two checkboxes for each.I need to be able to paste this in notepad and have it formated as such
I'm doing an assignment for Uni and in my VB.NET form I have some checkboxes, I'm trying to loop through and clear them (I have a button which will clear the form). My problem is that there seems to be no property I can use to set the state of a checkbox when not explicitly telling VB which checkbox I want to use. for example, I can go WineCheckBox.Checked = False
That will check the box, but I wand to DRY the code up a bit and not have to repeat this for each check box I have, this is what I was trying to do: If TypeOf element Is CheckBox Then element.Checked = False End If I've tried using element.CheckState and element.Checked and both times I get "Checked (or CheckState) is not a member of System.Windows.Forms.Control".
This is the whole block of code: 'clear the controls For Each element As Control In Me.Controls If TypeOf element Is TextBox Then [Code] .....
I have a group box which contains 40 checkboxes, when a checkbox is selected its content is added to a list and removed if already checked. Now I could write 40 functions one for each event (lots of code) each containing a add to the list function and a remove on uncheck, or I could use multiple handles (confusing multiple line declaration) is there another way? say my list of chkboxes had 100 checkboxes or more? can I for example use the container in some way?
Ok so with my program i'm trying to create a save configuration I have it in my context menu so that I can click save configuration and what i want it to do is check to see what check boxes are checked and save those to a file (i.e. a notepad file or whatever works) that way I can save categories for customers or my own computer or whatever and than i'll just click load and choose the category I want and it will load the checkboxes that I want to install. I found a similar post but it's not really making sense to me. So i'm wondering what I need to do to make this work.
I'm also wondering how i'm going to load the configuration but I might have to wait on that one step at a time.

Okay, so basically I'm trying to have my application randomly select items from a (multiselect) listbox. I want the user to enter the amount of items they would like randomly selected and it should all happen at the same time. I have the random shuffle down but it only selects one song each time you click the button. How can I loop this code as many times as the user specifies in the textbox?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As Dim shuffle As New Random Main.songlist.SelectedIndex = shuffle.Next(0, Main.songlist.Items.Count - 1)
I used BackgroundWorker to solve a problem in my winforms application, I wanted to be able to cancel a long-running operation and see results live in ListBox while executing the operation. It works fine except when I want to add a checkbox with additional condition. The problem is when I want to run several operation at once. Ex. both XX and YY executing XX first and then start with YY in that order.
Private Sub UpdateDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTestAll.Click If cbxTestYY.Checked OrElse cbxTesteXX.Checked Then SetBusyState(True) If cbxTestXX.Checked Then [Code] .....
I know I am trying to run multiple tasks on same backgroundworker which is not allowed, but I don't have any idea how to solve this so it runs in specific order.
I am trying to code something with nested for loop with the following format:
[CODE]...........
However when the program hits the last value of 'For loop 1', the nested for loops seem to only trigger once instead of the number of times that i specified.

I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.
Heres code to reproduce it. Just a button on a form. Dim intTotalTimesClicked As Integer = 0 Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click BlastOfNumbers() [Code] .....
I have set up text boxes for user to pick a number 1-20 and to enter a word as well. Then, press submit button. What's supposed to display in result textbox is the word that many number of times. For example if the number is 5 and the word is hello, then "hellohellohellohellohello" should appear. I don't know how to complete my For...Next function to append the word to the result.

I have 50 checkboxes for 50 american states. The user can choose all 50 or only 1( so basically any number he wants). Based on his choice, I want to insert or update the table in sql server 2008. e.g-
Color = blue and chk1=check, chk2= check and chk3 = check (chk = checkbox). now the user wants to ad 10 more states to this or remove these 3 and add 5 more. so u basically get the idea. the table in database looks like this - ID Color State_id there is a table called states, so stateid shall come from there. so how do i do a loop insert or update in vb.net?
I have a Main form, called Main.vb, that is a Parent Form. I have another form called Notes.vb. Inside Main.vb I have a toolstrip with a button on it called Notes. I'm wanting to change the checked status of the Button to either True when the Notes.vb window is open inside the parent or to false when it is close. Is this possible?
