ASP.Net Auto-populate Field Based On Other Fields?
Nov 15, 2010
how i can implement below requirement using asp.net and vb.net.I have three fields in a form which are filled by users. Based on these three values, i need to auto-populate the 4th field.I have planned to implement this in the following way.Write a separate class file with a function to calculate the possible values for the 4th fields based on 1st 3 inputs. This function can return some where between 1-10 values. So I've decided to use drop-down for 4th field, and allow users to select the appropriate value.Call the above function in onchange function of 3rd field and take and use the return values to populate the 4th field. I'm planning to get the return values in array field.(Does this need a post back?)

I am trying to auto populate some fields in my datagridview on my form called frmInfo.
I will try to explain what I need. The main form of my project is called frmEntry. frmEntry is mainly a data entry form only. A binding navigator is present to navigate between different record stored in the database. I want the datagridview on frmInfo to "grab" info present in the text fields of frmEntry.

2. Researched the process, requires knowing VB codes, are you familiar with this language? If so, how can I simplify the process? Please advise.
3. The files will reside on the SPP.

I have a table which contains a list of products for a company. They input data about how much stock they have and also the level at which they want to be reminded that they need to order new stock.
[Code]...
I want to list all the true results in a form which the user is then able to navigate through. What would be the best way to go about doing this?

CODE:
This tells me "End of Statement" is expected. I'm trying to instantiate a new form, and I'm trying to pass information into the form that I will use to populate other data fields on the form.
I've tried looking up constructors, but I can't find where my is different than other examples.

I'm quite new to VB.net (and VS 2008), so I'm afraid my question might be basic, but I'm not sure how to solve it.I have a winform with three textbox fields and a button. All textbox fields must be filled before the user can click the button to continue. To this end I would like to disable the button as long as there is at least one empty textbox.
If I had only one textbox field, it would be easy for me to do. In the Textbox1_Leave event I would check if Textbox1.Text is not empty and if so, set Button1.Enabled = True.But what should I do if I have three textboxes? Have three event handlers, one for each textbox? Or is there a way I'm not familiar with?

I apologize if it is not. I am trying to write a script in Visual Studio 2008 (using a VB project) that will, upon the clicking of a button:
- A file object will be created.
-Said file object will read in a number of files from a specified file path.
-A dataset will be created and populated with fields from two columns within a database table; app_id and company_name.
-The script will read through the file names and fields recorded in the dataset, renaming the file to the app_id if the original file name contained the company_name.
The code I have so far to do this:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
'Create the file object
Dim objFSO
The problem is that currently this code will only rename the file if the file name and company_name match exactly, ideally I'd need to include a clause to make it rename if the file name is "LIKE" or "contains" the company_name.

what I need to do is automatically (through a timer or similar method) look up a newly added record, and if it exists, have a number returned and populated to a specific textbox. I have the looking up the record and getting the field I want returned working fine, but I just cannot find any way to have it populate a textbox. Another small wrench in the works is that it's a web form. I think I'd be ok with a Windows form.The reason I need this is, the user will not be sure when this record has been added and it would work fine if they wanted to click a button until it is actually added to the table, retrieved and the number needed populates the textbox. However, the folks who gave me the spec prefer the user not to have to keep clicking a button for an undetermined amount of time. So, I've been trying to use a timer. I've tried everything I could think of to get it to populate the textbox. Even javascript didn't seem to work and neither did trying to a redirect back to itself. Everything is fine except for filling in the texbox.

I have a class (using a class rather than a structure only because I can set a default field value for the fields I declare in the class) and I'm using a web service that returns information (demographic information) in JSON. I am using LINQ to get the values of each "entry" from the returned list and in that, I have to parse through and pull out the actual data that I want.Here's how I have it doing right now (just a start, there are 44 of them total, thus my question which will follow the code):
Dim returnedStats = From ljo As Linq.JObject In returnedObject.SelectToken("results")
'

For Each stat As Linq.JObject In returnedStats

I have a form on an asp.net (VB) page which has 2 sections.
All of section 1 is always required, but section 2 is optional. However, if section 2 is started, then all fields are required.

Here's my code:

I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?

I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.
