VS 2010 : Make The Combobox Get Values From A Website Using The Current Keyword They Have In The Box Already?

Mar 14, 2012

I'm trying to make the combobox get suggested values from a website using the current keyword they have in the box already. For example if I have O, it will show up values that the website has returned with O. The problem is how can I make it work where whatever I type into the combobox, it will get the values, set the datasource and make it show up. So far I have this:The problem is whenever I type something, I cannot get it to set it to the new datasource without the comboxbox becoming the first value in the data source.

Dim pop As New List(Of String)
pop.Add("Koolaid")
pop.Add("kIMKY")
pop.Add("KoolPaid")
ComboBox1.DataSource = New BindingSource(pop, Nothing)

Store One Column Into A Combobox?

Nov 20, 2009

I have a table called PatrimoniuMasini.

What I need to do is simply copy all the values contained by column NumarMasina into Combobox1 of my Form. (i marked with red the values I need to copied into my combobox(combobox1 of my form) in fact there are 10 values I missed the last one. You can run the ddl provided below in sql server to see the output from my printscreen.

When I run the form in my combobox there are imported the values from NumarMasina column. (so this must be done in form_load callback it's sure).

Just need to import the values from column NumarMasina of table PatrimoniuMasini automatically into combobox1 when I start my application.[code]...

How To Store Values In Byte Array

Mar 29, 2009

I'm trying to convert old code to VB in VS2005. The code I'm working on is used to store values in a string, which will then be handed to a proprietary scramble function. This function is a given in this case. I've already switched from a string to an array of bytes in my .NET code.

The old code (VBA) was using a string value to store the data, example function for Double value:
Private Function DoubleToStr(ByVal value As Double) As String
Dim Bytes(7) As Byte ' 0-7 Double is 8 bytes
Dim n As Long
CopyMemory(Bytes(0), value, 8)
DoubleToStr = ""
For n = 0 To UBound(Bytes)
DoubleToStr = DoubleToStr & Chr(Bytes(n))
Next n
End Function

The code basically copies the memory contents (using API call CopyMemory) of the memory (held by the double variable) to the memory held by a byte array. It then reads the byte array and converts it into a string. Workarounds could be to convert a bool or long to a string, though that would be expensive in terms of memory/storage eg. 1234564787 would be 10 bytes in a string where as a long is only 4 bytes (factor 2.5 increase).

How to retain the original precision? Converting it to a string would result in endless numbers. Another problem (at least I think it could be) is that in VBA the variables are rather simple, but in .NET they are all objects, so how to retrieve the actual memory location of the value? let alone garbage collection moving stuff around. How to get those variables stored in my byte array?

Store Retrieved DB Values In Variables?

May 31, 2010

I have a database in my app which loads and displays some information on a form by binding the Comboboxes and Textboxes. However, I need to get some of the other values from the database for calculations before they are displayed on the form and I can't seem to find out how to do this.I could bind a couple of Textboxes to the database and then use those values to calculate, but it doesn't seem like a very efficient way of doing things.The dataset is created using the wizard and the controls are linked in the UI.

Please bear with me, I'm still a noob.

My application sends information from Form1 to Form2 by means of a global variable on Form1 whose value is read by Form2.

This variable is basically used to tell Form2 what it has to do because it's value will change depending on different conditions.

All form2 is meant to do is load data from a database into DataSets which will "ported" to Form1 (the main form) for consumption. I use a Form for this rather than a class because there's a lot of data that will be loaded each time it's visible and I wanted[code]...

Cannot Store Retrieved Values From Database To Array

is that instead of receiving data from one row and assigning it to the same array Im receiving data from multiple rows, but the information is the same because its from the same one column from the database. The error I keep getting is 'index out of bounds of array'

here is the code

What it does is it loops through once and retrieves the first value from the db then it throw the exception when it goes to retrieve the second value.

Dim qBkNum As String = "SELECT BookingNum FROM Bookings WHERE BookingID = '1'"
Dim bkNum(5) As String

Copy A List To Store Original Values To Be Used Later?

May 24, 2012

I have a WPF form that takes a list of objects that have locations and sizes and plots them on the canvas. I'm currently trying to implement an undo button that will throw out all the changes that have been made to the positions of the objects and revert back to the original collection that was retrieved when the form loaded.

As it stands now I go out to the database on the load of the form and get all the objects that will need to be displayed then assign the list that is returned to two seperate collections. The problem that comes up is that the two collections are actually pointers to the original collection and whenever one is changed the changes are reflected in the second collection.

Is it possible to copy a list of objects so that changes made to one collection won't affect the secondary collection?

So far I've tried simply using the assignment operator, passing the source collection into a function byval and scrolling through each element of the list manually adding it to the second collection and using linq to get all the objects from the original list and pushing the results to a separate temporary list and assigning the second collection to the temporary list.

I feel like I'm overcomplicating the issue but almost all the places I've come across while googling say that this behavior is by design, which I understand but it seems like this would be a fairly common idea.

InputBox Function - Program - Allow User To Input 5 Payrolls For Store 1, Store 2, And Store 3

Mar 22, 2012

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
