I can export the database part numbers into an array. I want to be able to search that array with predictive search. a good example is www.yahoo.com's search engine text box on the front page.
How do i achieve this within a windows form and not in a web project. I've searched around for this but have not found much of anything useful.
Thank you guys!
Patrick!

Have you tried using the Custom AutoComplete function of the textbox?
It is said that the most complex structures built by mankind are software systems. This is not generally appreciated because most people cannot see them. Maybe that's a good thing because if we saw them as buildings, we'd deem many of them unsafe.

I don't know if this is the proper way to do it but I usually do it this way.
1. Create a Datatable
2. Fill the Datatable with the column of interest (Select COLUMN from Table)
3. Use a foreach loop to go thru each row
4. Use a StringBuilder to append those rows
5. Attatch the StringBuilder to the textbox.
I usually doesn't any encounter a very long initialization time using this method. I used it in one of my OPAC projects.

Hi,
Two comments:
1. I suggest you have a look at String.StartsWith()
2. You might want to store the results of cachedPartNumbers[i].ToString() rather than calling
it all the time

Hi,
My code is looping through records and adding items to a listbox as below:
forloop
{
lstBox1.items.add("item1");
lstBox1.items.add("item2");
}
Question:
How can I change the colour of SOME of the items as they are being added?
Thanks

Hi,
there are two basic features you need:
- ListBoxes can contain items of any type, not just strings
- you can paint those items yourself (DrawMode OwnerDrawn, event DrawItem)
So the neat way to do this is define a little class (say MyItem) and let it hold a string and
some style field (maybe a Color). Add instances of that class to the ListBox, make it OwnerDrawn,
and provide a DrawItem handler according to your wishes.
As a shortcut, when I only need two variations (say black and red), I skip the MyItem stuff and
prefix the red items with a special character (say '~'), then in DrawItem check the first char,
and if a '~', choose Color.Red and drop the '~'.

Hi,
I am not a good c# developer so not sure how to do what you suggested.
Can you make it simpler or guide me through it further please?
Thanks

Sorry, no spoon feeding here. I gave you all the required keywords, let Google and MSDN provide you
with the details; and CodeProject holds thousands of interesting articles too.
PS: don't switch Controls, if ListBox is your first choice, stick with it. It is a very good performer.

For a start, the loop is incorrect. It'd probably be something like this
for(int i = 0; i<3; i++)
{
lstBox1.Items.Add("item" + i.ToString("N0"));
}
Also, the standard ListBox cannot do that on its own. You could paint it yourself if you have a good grasp of the Graphics object, or you could use the ListView. The loop would change to something like this
for(int i = 0; i<3; i++)
{
ListViewItem lvi = new ListViewItem("item" + i.ToString("N0"));
lvi.BackColor = Color.White;
ListView1.Items.Add(lvi);
}

Do you know why I do not get Color in the intellisense please?
Thanks

to the top of the file?

Hello,
I am working in my application with xml files and mdb file,I don't want user view these files I want to put them in the app assembly.
Thanks.

yes it works for xml files but I don't know if mdb will work or won't work.
1. add a classLibrary project in your solution,
2. add the xml files into your new classLibrary project.
accessing to xml:
System.Reflection.Assembly xx = System.Reflection.Assembly.Load("yourNewClassLibraryProjectName");
string ress = xx.GetManifestResourceNames();
and you will read with xmlSerializer.
I'm not sure if you can change dinamically that xml files or not...  .

The only real purpose of including the mdb file in the assembly is to have an already structured template for database creation/editing. You would not be able to edit the files embedded into the assembly. If you want to 'obscure' what the user can and cannot see with regards to the actual database file, I would suggest that you give it a 'critical application important file' type name. Second I would suggest that you give it an abnormal database extension. Ex. For my RevCorp accounting software I wrote, I labeled the file: AppData.revdb. Their was a copy of the file stored in the assembly. When the file could not be found in the directory where it was run the database was created from the assembly.

Not unless you have written some code in your app to do it. Google for .net deployment, there are loads of articles showing the problems and pitfalls.
