I need to populate values from a database(Access) in to vb.net form. after selecting a field from first form, the next form should display all the parameters used in the selected field from the data base. Also if do editing it should be updated in the database.
View 4 RepliesUsing 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.

I made a quick search but couldn't find any help I need to put the values of a checklist box into an array. I've found several solutions on the internet but all of these don't seem to work for integer arrays. This is what I've got so far
" Dim RemoveValues(checklistRemoveBrew.CheckedItems.Count - 1) As Integer
Dim C As Integer
For C = 0 To checklistRemoveBrew.CheckedItems.Count - 1
RemoveValues(C) = checklistRemoveBrew.CheckedItems(C)

I am populating a collection from some tables in the database which serves as a look-up from controls (combobox) I am using but what I want is rather than hitting the database each time can I just cache the collection and get the collection from the cache? The look-up table may or may not change all the time so I would want to have a way to validate if the cached collection is still valid or not.

View 1 Repliesthis is how I set up my data object for a file parser. (
Dim mytable As New List(Of String(,))()
mytable.Add(New String(4, 16) {})
and it loads mytable like this:
mytable(x)(y, i) = sToken(i)
Let me explain the indices, I have a form with a tab control. In mytable,x is the tab number. Each tab has up to 5 groups which is y. Each group has 17 text boxes, i.Each group also has 17 labels.I started looking at Me.controls, and looking at control properties like tabindex for some way to iterate through the textboxes and mytable to load the textboxes.
so I started with:
for x = 0 to 31
msgbox(group1.control(x).text
next x
and I saw how all my objects are not in sequence as it descending halfway through my label controls, then switched to my textboxes, and then seemingly finished randomly. I am at a total loss without the old index property and what I want to do is something like (forgive my syntax)
Form(0).Tab(x).group(y).textbox(i).text = mytable(x)(y, i)
I was thinking of manually setting the tabindex of all textboxes in group1 to sequential order to try something like:
group1.component.tabindex(i).text = mytable(x)(y, i)
To me this is fun and challenging, but also very frustrating and makes me miss coding in assembly As I can't seem to find any reference to the tree structure of accessing components indirectly, if that makes sense.

I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?

Im taking over a project that pulls information from a database.Currently I have everything I need except the username.The person who setup the project did it as a web project so he used the MemberShip class to create unique user keys based on the person's username.
The username is not stored anywhere in the database only these userID keys.
The client wants a desktop app that mimics the website behavior of writing to the database.
Problem:I ask the user to enter in a username at the login. The username connects to the database on the server.I have no way of grabbing any user info after this point as the primary key(USERID) is a unique key and not a username. Is there a way to convert a MemberShip ProviderUserkey into a string Username or am I screwed?
I have a combobox which contains few objects in Items. When the user selects any item from the combobox the values from the Object member variables are stored in the textboxes on the form.The user will change the values in the textbox and then he will select another item from the combobox.

I have code like the following:
Dim Flag as Boolean
Flag = Function1ReturnValue
Flag = Function2ReturnValue
Flag = Function3ReturnValue
Now ideally 'Flag' should only have a true value if all three of the functions returned 'True', but as it stands now it won't do that. There needs to be an 'and' or an 'or' or an '&' or something like that, but I'm confused as to what needs to be.
