I would like to receive user input from a JavaScript prompt box, save the value entered and then insert the value into a database. I am using VB.Net and MS SQL Server 2008. How can I do this? I tried using an inputbox, but it didn't popup like a prompt box, but rather, I had to click on it for it to show up, which is not user-friendly. Is there a way I can achieve what I want to?

How would I go about having my application automatically close an onbeforeunload prompt box that warns you before leaving the page?
Example: [URL]
1. My input box does not prompt
2. Then a loop should be used to display in a list box the distance the vehicle has traveled for each hour of that time period.

I need to prompt the user to input a few key/value items.Instead of building a form with a bunch of label + textbox, I figured I could use a simple, unbound grid.
I know the ListView widget can be displayed as a grid, but it appears that some added code is needed to make it behave that way.If you've investigated the matter recently, which solution did you end up using?

View 1 RepliesI have been learning a bit of jQuery and .Net in VB. I have created a product customize tool of sorts that basically layers up div and add's text, images etc on top of a tshirt.I'm stuck on an important stage!I need to be able to convert the content of the div that wraps all these divs of text and images to one flat image taking into account any CSS that has been applied to it also.I have heard of things that I could use to screen capture the content of a browser on the server which could be possible for low res thumbs etc, but it sounds a little troublesome! and it would really be nice to create an image of high res.I have also heard to converting the html to html5 canvas then writing that out... but looks too complicated for me to fathom and browser support is an issue.I'm thinking perhaps I could do with two solutions for this. Ideally I would end up with a normal res jpg/png etc for displaying on the website, But also a print ready high res file would be very desirable as well.

View 3 RepliesI'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}

View 1 RepliesOk, as you can see I am totaly new with Visual Basic. I have learned all those loops, if&else statements, byval, byref and etc. But now, I want to create this kind of application. I have 3 textboxes. One will contain URL, second username, and last password. There is a listbox also and a button. I want when user add a values inside textboxes , that values go to listbox as one variable and then save those settings for user so when he start up application again there are saved variables inside listbox. I just dont know how to do that.

So far i have a really basic form application that allows a user to enter some information and does a small calculation, displaying all of the information gathered on the final form.
Im looking to try to save this information but have no idea where to start,im trying to just take whatever is in my text field and put it in a table row. I created a one table database in Access and linked it to the form with a button to try and save it.
I thought it would be as simple as tablename.rowname = textbox.text or something but apparently not and all ive ended up with so far is this:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Me.Validate()
Me.TblCustomerBindingSource.EndEdit()
Me.TblCustomertableadaptor.Update(Me.DatabaseDataSet.tblCustomer)
End Sub
I dont even think im close, ive just been fiddling with the predefined code in Visual Studio, trying import ect but the button just doesnt seem to do anything.
I'm a novice, messing around with input boxes in VB 2010 Express. I know most programmers recommend not using input boxes except for the simplest things, but what I'm doing IS the simplest thing. Besides, I'm really just experimenting for the sake of learning.
I want a few input boxes to appear, one at a time. Let's say there are six input boxes in this project. The user can input anything he wants in each input box. After the user has entered text into the six input boxes, the program should write the text to a file. This is the part I'm having trouble with. [Code]
I haven't figured out if title.input is correct or not, or if I need something instead of commas in between each item. And the headers (i.e. the "First Name" stuff) needs to be added in there also, but I need to get the syntax of the code right first before getting to that.
For example, I clicked the Add Text box button, so it added 3 text boxes in the form (I used Dynamic text box so it can add multiple text box). When I input data to one of those 3 text boxes and then Save button has been clicked. It should checked whether the dynamic text boxes are empty or not. If there are empty text boxes, then saving data to db should not be continued and display a message telling the user that empty field(s) are invalid.
In the code below, it saves the data even if there are empty text boxes and I think because it is in the for loop, it checks the text boxes one by one and repeatedly displays the message box that I coded.
Here's the complete code:
Imports System.Data
Imports System.Data.SqlClient
Public Class Form3

I had an Excel spreadsheet which I put in MS Access (database). I then took that database and used that as a source in VB to create a GUI for. In VB I have an input text box to search and pull of different fields. I created some queries for searches in from the text box. I have have a dataset view of the data which has the binding navigator (add, insert, save).
The problem I have is that when I hit the '+' for add to add information and then click the 'save' button in the binding Navigator, the information I put in does not save. I check this by exit out of the program run (debug to open the app) and then open it back up to search and/or check for the new information I put in. My overall goal is to create to publish the final code and use an a standalone program.
Also, as another option,(I would like to learn) Is there a way to map VB directly to an Excel file to have the user input information and save to the excel file.
i am using vb.net with asp.nethow am i going to check that this class has 10 people already if i continue adding the 11 one it should prompt me that the class is full once i click save button, i know is something like validating but not sure howi can first add a few student to class 2A and later on continue with adding to another class however, when i return to add more student into 2A and save, it should help to check like what i mention above i have this table call listOfStudent

I have deployed a Visual Studio executible module written in VB Net 3.5 SP 1 with Crystal Reports. When the user tries to view a report(s)they are prompted to login in to the data base that has been data sourced into the report module. The correct database was verified before the build was made. The developer is able to run the report in a run mode on the local machine where the VB project was created. In the properties section in the project the following check boxes pertaining to reports were checked on:
Crystal Reports Basic for Visual Studio 2008(x86, x64)
Microsoft Visual Studio 2008 Report Viewer
Notes: If the executible module is deployed to a machine that has Visual Studio 2008 installed, the Reports run fine without a database login prompt.If the executible module is deployed to a machine that does not have Visual Studio 2008 installed, the user is prompted for a login. The data base is a SQL server 2008 database.

I have managed to create a connection to the database and am able to save information to it from my form, the form contains 22 textboxes, a save and another exit button. I have set the form to retrieve data in the form_load. I have used the "UPDATE" SQL command on the save button and it does save the data on all 22 textboxes (all textboxes are linked to their separate columns). But only one record will be needed that is why I did not use the "INSERT" command.
The problem arises when I click the save button, all (19) textboxes are saved but when I retrieve the text (by reloading the form), each of the 20, 21, 22 textboxes (only) the text of the 20th textbox keeps on moving tho the next textbox e.g. 20>21>22>20>21>22 is interchanged amongst themselves.

I'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?
- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.
- I can afford delay in the sql database, meant the data might not be necessary close to real time.
What is the best way on saving changes in datagridview into database? Whatever the user made changes in the datagridview will reflect right away in the database? The fastest and accurate way.
