Im using a bindingsource to add new records to my db using bindingsource.addnew()When this is evoked, it seems to automatically increment the recordcount and then blanks out the content of every bound to that tables bindingsource. So that all fields in the new record have to be filled in manually.I would like to be able to pre-fill some of the data in the new record. for instance, when a user adds a new record, have a specific column in the new record automatically populate with the selectedvalue of a combobox.I assume this means I may have to manually code up my own addnew routine, but google has let me down on where to start.
View 3 RepliesIn my form.load event, there is a bindingsource.fill event.After the .fill, there are two or three other lines of code that query the newly filled tablemanager. The code gets the number of total records and displays that number on the form.Here is the problem ....When the .fill statement is executed, control reverts to the form and any statement AFTER the .fill event is not executed.I have tried to stick the remaining lines of code into some other form event with little success. These three lines of code only need to run once.Does anyone have a suggestion as to where to stick these lines?

list the steps to fill a combobox using a bindingsource. I dragged a bindingsource onto a form, created a datatable and datatableadapter(correct term?), added a query. I tried but I am missing something, my combobox displays System.Data.
View 5 RepliesOn a Windows form, is there a way to have 2 combo boxes bound to the same bindingsource, but allow the boxes to display different values? The bindingsource is basically customer number and name. I want two combo boxes so the user can choose a starting and ending customer range. When both boxes are bound to the same bindingsource, when either combobox value changes, both boxes get the same value. I am using VS2008, .Net 2.0. Two bindingsources would likely work but seems highly inefficient since the data is the same. The list of customers could potentially be 50,000 records or more. Is there a better way to implement this range option besides combo boxes?
View 4 RepliesI am trying to fill a combo box from SQL Server 2008. Getting the Combo Box to populate isn't the problem. What I need to do is have the text field read the field value that goes with a specific id that I search by, while keeping all other fields available to chose from to change the value for that specific id and save back to the database. I know this isn't clear here is the best example I can think of:
COMBOBOX --FieldValue------->
--DropDownField1--> Ten
--DropDownField2--> Twenty
[Code].....
I seriously might have to infest in some Rogaine if I have to spend another ten minutes on this. I do know that I am missing an id to compare to but when I add the id into the sql statement the combo box only fills with the one value that it equals to without the option to chose from the several others to change.

I ahve a combox (cbnames) on a login form which is populated with items. I make a selection and click on ok. Form1 appears and I have a textbox which I want to fill with the selected item from the combo box.
However, on form1 (view code) I don't appear to see cbnames. cbnames is available on the login form. How do i make a combobox public? or accessible to other forms?

As the title suggests I have a ComboBox and 2 listBoxes on a form. I need to fill the left ListBox with items not now asssociated with the ComboBox selection and the ListBox on the right with items already associated with the ComboBox selection. Is it possible to populate the ComboBox and each ListBox using only one query and returning a dataset of ALL the data to do so, or do I need to Populate the ComboBox, then use 2 queries, one for each ListBox?

View 1 RepliesSo im trying to fill a combo box with data from a database but depending on how much a pregressbar is filled THis is what im trying:

I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"

I have combo boxes for user choices on the form. One combo box for name, one for phone number and one for email. I first created that to allow user to make select in each combo box. As more "user friendly" interface, I I would like to associate the selection made on cmbBxReqstrName with corresponding phone number and email and cause the phone number and email combo box to "auto fill" in their respective combo boxes based on the selection in the cmbBxReqstrName. It was suggested to me that a two dimesional array might be an option. I read up on arrays but don't quite comprehend the coding part to access the data in the array and fill that to the combo box or I guess use the index from array to index the combo box list.

View 2 RepliesMy next project is this:
I have a customer service center where each person must fill out the same data on 3 different web forms for each phone call. All 3 browser windows are open at the same time. (we are forced to use IE at this time)
The fields on each form are the same, but may be in a different order or called something different, but the data is ultimately the same.
Submitting to these web pages through POST is NOT an option. It must be done in macro-like style.
The hard part about this for is getting VB to focus each window one-at-a-time and then filling in the form values.
How can this be done? After focusing windows, is there a way to get VB to fill in each form field?
I'm in the process of adding EMR (Electronic Medical records) to my app. We have many PDF files that where created in Adobe LiveCycle and Acrobat Pro. Not sure if this is possible, but what I'd like to do is open a PDF file within my app and display it for the user to fillin the PDF form. Once PDF is filled in, I'd like to be notified (user clicks submit) when user is done, then get data out of PDF and save it to database. Or be able to fill in a PDF automatically and then display it to the user for editing. I know there are many tools out there to create/edit pdf files. The Acrobat SDK also includes a PDF viewer control, but the problem with this control is there is no way (I've found) to also edit the file through my program because the control don't expose the AcroForm class through the control. BTW, it this can be done PLEASE let me know how. Also note that most of these are dynamic PDF files (created in LiveCycle) and some of the third party tools don't provide support for these files.
I don't care if Acrobat reader is required to be installed on the user computer, I just need to be able to get some type of notification that the user is done filling in the forms. It might have been easier to just create a winform and with all required fields, but a lot of our users are not computer savy, and have been using the paper version of the PDF files for a while. I need to make it as easy as possible for them to jump in and start using the program, hince embedding the PDF into my app.
I'm trying to fill in web forms automatically by using the vb.net webbrowser. I'm using code like the following to fill in the name:
Dim elementsInput As HtmlElementCollection = wb1.Document.GetElementsByTagName("INPUT")
For Each element As HtmlElement In elementsInput
[Code]...
The problem is this solution is not global. It will only work on text boxes with the name "OWNER_NAME". Writing out hundreds of variations for every text input there might be for name would not be very smart. There must be an easier solution?
how I can write a program that will work on ANY web page, no matter what the names of the text inputs are?
I have a listview control that contains 2 items, ProdCode and ProdName. When the user clicks on the Prodcode, I would like the Prodcode to be entered into a field on the form. at the same time, the ProdName should populate the ProdName field on the form. Below is the code to get the data for the ListView.
Dim objListViewItem As ListViewItem
'Initialise a new instance of the data access base class

I am newbie in VB.net so maybe what I will ask is very simple.I want to create an application in which when ser clicks the button the first time a picture be shown on picturebox1user clicks the button the second time a picture be shown on picturebox2user clicks the button the third time both pictureboxes would be emptyuser clicks the button the fourth time a picture be shown on picturebox1

I would like the main form I am designing in VB.net to appear as quickly as possible. As a result I don't want to fill a datatable in the load event but instead fill it as soon as the form appears, in the background.Then when a user clicks the button a listbox can quickly be populated.
With this in mind I called a function to fill the datable from the _Shown event. The trouble is that the form freezes until the query executes, making the process pointless for my needs.
Does anyone know how to keep the form active while the datatable fills silently in the background?
Well, my problems is follow. I use a textbox where the user can enter a text but which I would like to prefill out with a variable (later , with more experience, want to ask the AD for the username and put it in the box).
That means, when the user runs the app, automatically is the username written in the textbox without pushing a button but the user has the opportunity to change it (For example doesnt want the second surname).
I have a database set up in Access. Currently I have 12 exact copies so individuals can enter data. We use the data to fill in multiple forms.I know that VB can be used to allow everyone to access one database. Does anyone have this as a runtime module since I have never written in VB and don't know where to start. My last code writing was on a AS400.
