Here's the situation: I've got a form that has
- RichTextBox
- OpenButton (to load RTF file)
- SaveButton (to save RTF file after editing)
- Textbox (for search phrase)
- SearchButton
- ExitButton
- 2 RadioButtons (WholeWord and MatchCase search)
All of them are working just the way I want them to except search features; I don't know how to write them properly. At the moment, they search and highlight only the first word they encounter. E.g. say I search for word "the" in the document, only the first "the" it encounters is highlighted. The rest is just untouched.
I understand this is because I've only got few lines of simple code as follows
If rtfText.Find(txtSearch.Text, RichTextBoxFinds.WholeWord) = -1 Then
MessageBox.Show("No results returned. Please try again.", "No matching results.", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
I did try a few other snippets I found on the Internet including While loop but they didn't work as I wanted them to, and I couldn't understand them either. What I want is, which ever search option is used, when the matching result is found; it will highlight that word and when I click it again it will move onto another word. If I keep clicking, it will highlight the same words (but located in different areas) throughout the whole document and at the end, it will send back to the first matching word. Just like Adobe Reader search.
I'm creating a search application that needs to have a fuzzy search. Basically if there are 0 results, I need to provide a suggestion, much like google. For example, if I type "Californea", I need my program to suggest "California" after doing a query on my DB for similarity.

But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?

I've been working on some autocomplete abilities for a webbrowser I'm building, rather like in IE or Firefox. This is what I mean: I have absolutely everything working - adding search providers from webpages, getting the search suggestions as an XML file from whatever provider may be being used, and adding them in a multithreaded manner to the combobox with all the suggestions in it.
But there's a problem. Due to the fact that the search suggestions are only retrieved (in a matter of milliseconds) after the user has typed something in the Combobox, the suggestions only flicker up, as they are modified just after the text is changed, therefore I get an effect like this:
Again, I'm pretty sure I'm getting this effect because of the fact that I'm adding the Auto Complete suggestions to the combobox right after the text is changed - so they just hide themselves again - and this process is repeated. Does anyone know any way in which I might be able to stop this disappearing from happening? Because I've had a good think about it and I can't really think of any workarounds.
I have a class that has a property that I declare like this:
VB.NET

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
View 7 RepliesI am Looking for a combobox that does a full search and O mean by that the following :
It starts searching data upon inserting or adding new character to the textbox of the combobox and vice-versa, which means that if I moved back by deleting a character then it starts searching again selecting the first data resembles the textbox. In another way I want a combobox class does exactly the same as combobox in Encylopedia.
ive got a small code which takes a strign given by the user, searches for all folders with in a folder for matches then lists them, which is this:
vb
If e.KeyData = Keys.Return Then
Dim lb1s As String = Application.StartupPath() ''The folder to search in
[Code]....
The results are added to a listbox and all works great, but how do i get it to add partial matches aswell? For example if the search string is 'testing' and theres folders called 'testing on' 'testing testing' etc to show those in the results aswell?
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?
