VBNet Textbox AutoComplete - vb.net

i was wondering how some programmers made autocomplete functionality such that it also matches character within the string.
Like for example, there are current records in the table of the database and these are:
Ants
Apes
Bats
Bees
Cats
Dogs
Elephants
When I start typing letter "E" in the textbox, i want that the autocomplete functionality suggest these records:
Apes
Bees
Elephants
since all these string contains letter "E"
hope you can help me with this one. thanks :)

The native controls will not work that way (as far I've I can tell); when you use the auto-complete features, it starts populating the list with matching the start of the word.
You'll have to extend the functionality for auto-complete by implementing custom logic to perform substring searches to populate the match list. There is a promising question and answer on SO for this already.

insert combobox
insert items into combobox
set dropdownstyle to simple
set autocompletemode to suggestandappend
set autocompletesource to listitems

Spotfire: Need to select all values in a Multi select List Box Document Property

I have zero knowledge of coding. Can someone please help me with code.
My situation is as follows:
Dashboard has a Multi select List Box (Document Property). I am using that to restrict the data and calculations.
User does not want to select values each time. He wants a button where in (s)he click it once and all the values present in the list box gets selected.
Can someone please help me.
Regards,
Subro
This is fairly easy to do. Let us say that the Document Property that the list box is used for is named "Test" and it is of type "String List". Then you can use an IronPython script like so:
Document.Properties["Test"] = ["First Choice","Second Choice","Third Choice"]
Where the string list you see above, are all the values in your list box. Make sure that the strings you assign to the document property are the ones you want to populate your list with, since sometimes the displayed values can be different than the ones assigned to the document property(The case of using the "Fixed Values" option when setting up the control).
Hope that this helps.

Is AutoComplete Possible in a Combo Box?

I have created a Userform with a ComboBox for purposes of entering client names and information about their children, their names addresses, etc. The data entered will be used to populate various legal documents, and in many cases the clients will select their children (and the children's information) repeatedly. Understanding this to be the case, I have each entry .AddItem'd to the ComboBox List as I enter the data. So far so good.
But I am now trying to set the MatchEntry property (or something else in a manner which will allow me to "find" a former entry in the list and then select it or override it). The MatchEntryFirstLetter property, if active and nothing matches it, won't allow a new entry, it just flashes-back with the letters I type. MatchEntryComplete forces me to use a former entry (for instance if I have earlier entered the client name in Lower Case, MatchEntryComplete finds the Lower Case name but won't let me override it with an UPPER CASE version. Ho-hum.
So before I struggle further (and abandon this to MatchEntryNone), is there a way to structure the ComboBox (or is there a form of VBA code) such that as I enter text in the ComboBox it will simply "search" for a match, and then release me to either select the match or override it with a new entry?
Thanks in advance for your answers.

AFAIK, ComboBox already have that feature.
You just need to:
set MatchEntry to 1 - fmMatchEntryComplete
set Style to 0 - fmStyleDropDownCombo which are actually the defaults.
Consider below:
Private Sub UserForm_Initialize()
Me.ComboBox1.List = Array("Entry1", "Option1", "Item3")
End Sub
Say we have a UserForm1 with 1 ComboBox named ComboBox1.
If we run the form, it will look like below after typing O and p.
If you type another letter say y, it will automatically be overwritten.
If the searched match already satisfies your search, the just move on to next control either by using mouse or Tab key. Is this what you're trying to do or did I misunderstood your question?

How to set value in the textblock based on other textboxes and query in Access?

Right now I have such form:
The aim, that I'm trying to reach, is to open another form based on block_id value by pressing button. And it works. But block_id value in textblock should be based on three other values in the form: N_table, target_table and source_table. In the attached picture can be seen block_id's textblock form options. Source values for that textblock is query with name s2, and I tried to limit block_id value by setting filter here this way:
([s2].[N_table]=[Form1].[Список0]) AND
([s2].[target_table]=[Form1].[Список2]) AND
([s2].[source_table]=[Form1].[Список4])
There s2 is the query name, Form1 is the name of current form, Список0 and so on is the just list of values for first 3 textboxes. However that doesn't work at all. So block_id is independent. That is wrong here and how it can be fixed?
PS I'm really sorry for not english language in the attached picture, I can't change the language. And I tried to deal with the problem by using Event Processing macros but failed.
I can't read your language, but it looks if the FilterOnLoad property is set to No. Change it to yes, then it should work.

How can i set an Horizontal scroll or multiline text on a Combobox ? ( Vb.net)

I ' ve a combobox with too long multiple Items . There is any method to set a horizontal scroll in combobox or set a multiline properties for each item ?
Hi Mattia,
There are a couple of methods that are usable as well as effective for this problem you are having, here is the concept that I've created that you may implement in your project;
Original text: C:\path1\path2\path3\path4\file.exe
Combo Box text: C:\path1\p...file.txt
To do this you will 1st have to specify how many characters you want to shown in the start of the text (1st 5 or so) then you must specify how much you would like to leave off at the end (last 6 or so).
I realize this causes a problem, "I wont be able to see the full path!", however adding a 2nd form or a msgbox to display the full text which should initiate the 1st 2-4 secs of display time, this should not be a challenge nor a problem and will make you look like a Pro!
I hope this helped you with your problem or motivated you to go over and beyond!

choosing the right control for developing windows application

I am looking for a contol either listbox or listview to support my requirements.
Basically how my application looks is:
alt text http://img51.imageshack.us/img51/451/39967846.png
The background should be black
when the user clicks any 'row' the
row should get highlighted witgh
grey.
The user will have the ability to
search items in this control.
For example , if one of the row
displays 'This is the second Item in
this car'
If the user searches for Car, that corresponding row(s)
should get
highlighted with pink.
The user should be able to search an item in this contol and specify a number to display the lines below the searched row.
For example, if the user Searched for 'car' 5, the rows that have car should get highlighted and their immediate 5 rows.
I mean
Search Result :
car row
next row 1
next row 2
next row 3
next row 4
next row 5
car row
next row 1
next row 2
next row 3
next row 4
next row 5
The user
should be able to drag and drop the
files and they should get opened in
this 'control' i.e each row should
display a new line till the EOF.
The user
will have the ability to right click
on the row, context menu pops up
displaying that row item.
The contol
should be able to display specific
text items in a row(s) with
different color.
Having said these things. I used to program in VC++6, VB6. But using those version now seems not realistic now as I lost touch. But if I have to use the latest 2008 versions, for which I do not have any experience seems scary.
So, If you are reading this , and you have got some experience in these fields or using controls that support my requirement, can you please let me know which programming language or IDE and Control should I use to develop this application.
PS: the image is made using mspaint and does not represent actual program.
As for language I would suggest either C# or VB.Net. They are both great languages and there is tons of support on the Internet for them. Just pick the one you are most comfortable with. As for a control that does what you are asking,
As for the control, it really depends on what platform you target. I have very little experience with WPF so can't help you with that. However, if you want to use WinForms, I would suggest the ListView control. It provides a lot of flexibility in terms of how you can use it. You will need to write the code to identify the rows and highlight them, but that shouldn't be too difficult once you understand how the ListView works.
Here are a couple tips if you do use ListView:
Set ListView.View to Details (this provides you with a grid-like control)
Set ListView.HideSelection to false
Set ListView.FullRowSelect to true
Set ListView.BackColor to Black
Set ListView.ForeColor to White
You can hide the column headers by setting ListView.HeaderStyle to None
If you want to support selecting multiple rows, you can set ListView.MultiSelect to true
To highlight row, set the ListViewItem.BackColor and ForeColor
The big let down of this control is that you don't have much control over the color of selected rows. There are techniques out there to control this, but it's not a simple property set. If you are interested, I think this question/answer might help.
