VS 2008 Populating New Form With Data?
Apr 24, 2010
What I want it to do, is when a id is selected to be modified, another form will pop up with the fields are filled in with the relative data. Every time I run this I keep getting the following error -- "Syntax error in string in query expression '(the wombat ID selected)'"when it gets to the following line of "fillformDataReader = fillformCommand.ExecuteReader()"What is going wrong and how do I go about fixing this error so the new form is populated with the correct data?
Dim fillformCommand As New OleDbCommand
Dim nameView, idView, regionView, sexView, ageView, weightView, lengthView, sampleView, commieView, descriptionView As String

I 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 am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net
Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Text = "Line " & LineNumber & " Test Form"

Can someone help me with this code? I just need to make it so there is no limitation on how much data is loaded in the columns or rows, it populates very nicely for smaller comma delimited files , but if I try to load something that goes for example over to AV column, it errors out.I don't care about VIEWING this data, I am just trying to get it into a LISTVIEW so I can access the data for other methods in my code.Index was outside the bounds of the array.

Using VB.Net (Windows Application)In the form (called as FirstForm), i am using textbox, add-form Button, search button.When i click the add-form button, it will give the new form (same as FirstForm)Code for adding new form
Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click
Dim SecondForm As New FirstForm
SecondForm.Show()
End Sub
Search Button Code
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If FirstForm.Focus = True Then
FirstForm.textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
[code]....
The above code is working, but If i am in second Form when i click the search button and selected the value, then the value is appearing in the FirstForm textbox, it is not appearing in the SecondForm textbox.If SecondForm is showing, the selected Value should appear in the SecondForm textbox not in the FirstForm Textbox.

[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
Dim pattern As String = "([w:\w /]([a-zA-Z0-9-]+?).w+)"
Dim reg As Regex = New Regex(pattern, RegexOptions.IgnoreCase)
Dim mat As Match
For Each Item In lstFiles.Items

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. Cant really seem to get the table to fill, it appears always with blank fields, and tried many different ways. Currently using vb. net 2005 msvs.[code]

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.

I am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.

Let's say I have an employee class with ID, Forename, Surname, Initials and Email Address properties.
At present, you can construct an Employee object by passing a data row which, typically will include all these fields. However, sometimes I only want the ID, Forename and Surname but still want to populate an object.
[Code]...
However obviously if certain fields are not present in the data row, I will have an error. Is there a quick way of populating the object based on the fields that are present within the data row without a) having to have separate subs for each circumstance and b) without having to try / catch (or something similar) around each property? I know other languages have options like this - where if there is no value, it will be another value (i.e. a default).

Heres my issue, I am retrieving data from xml and populating a DataSet with the results into multiple DataTables but i have an issue where an item is repeated in my input data and it is causing it to exception because of the constraints imposed between these tables. how can i determine if a row exists prior to adding the DataRow and thus not include it in my DataTable?

I am building a form in access database.
I have a combo box which is linked to a query which is looking up a unique reference number from a table called Tbl_Submitted_Requests.
What I need the form to do is auto populate the other text boxes when the user selects the unique reference from the combo box. How can I get the text boxes to auto populate with the data that is associated with each unique reference?
