I have a textbox that is filled using autocomplete. The autocomplete is a globally accessible sub that I use for textboxes and (I guess) comboboxes.My problem is that the autocomplete sub takes several seconds to fill the textbox. Is there some way my code could be improved? (The code below takes three seconds to fill for 288 autocomplete entries, which I don't think should be a lot for this kind of functionality.)
My best bet is that the autosorcecollection has to redraw itself every time an entry is added, and that causes the delay, but I'm not sure.Apart from taking time I think this global function is really handy, so feel free to use!

I know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.
Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?
When I use the code below, I can't get any (copy)effect as I drag things onto the picture box(img). Therefore, I can't dragdrop files. How can I make dragdrop event possible?

how i can make VB to write the data from my textbox to a .txt , making it a log. The thing is my textbox is multiline, but when i log the data to the .txt it perfectly works BUT it doesnt do it in a multi line way. For example this is MY textbox:
[Date/Hour] You have entered the matrix
[Date/Hour] Thanks for entering the matrix.
and this is how it logs to the .TXT:
[Date/Hour] You have entered the matrix [Date/Hour] Thanks for entering the matrix.
This is the way i use it :
Private Sub CloseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SalirToolStripMenuItem.Click
RichTextBox1.Text = RichTextBox1.Text & vbNewLine
Dim FILE_NAME As String = "C:log.txt"

View 3 RepliesI am trying to design a basic version of spaceinvaders. I have 6 pictureboxes on my form and the idea is to add a value to the picbox.top property that moves the boxes down at a certain time and speed that i have set in my timer control. The problem i have is i am trying to set properties for all the pictureboxes at the same time by using arrays.
An example would be
dim mypic() as picturebox = {pic1, pic2, pic3, pic4, pic5, pic6}
pic1.top = 10

I have this program, where the main (one and only, "ControlBox" set to "false" and "FormBorderStyle" set to "none") form will fill up the whole monitor. It wasn't set to "WindowState" = "Maximized", but rather I have it designed to fit on the resolution of the target monitor's resolution size. It is set to run on 1920 x 1080 size. Hence I have all the layout and child controls laid out nicely.Right now, I was thinking, what if I wanted to have my program fit snuggly (or nicely) into the target monitor's resolution, varying from 800x600, 1024x768, 1440x900 and such.What would be the best approach? Make multiple copies of the form in designer, lay out those controls, then create a centralized class file that sort of integrates all the methods that were existing in the original form, so that the rest of the form would be sharing it as well.
Or would I make only 1 form and do all the layout adjustment on runtime and having the hassle and pain of going through it? I have 1 main problem though, there's this logo which stuck on the top left portion of the form, which currently just fit nicely on this 1920 x 1080's form. I wonder what would happens if I size it on runtime.

I would like to ask : how can i make to support the cloud technology.
Do i have to first find a server that provides cloud services ? Or does the user provide his own custom credentials and server somehow ?
Also, what .NET technology is there for cloud services ? Azure ?
Do you know any good examples / website for that ?
If i develop for Azure will the same code run also with Amazon web services ?
I am developing an appilcation which requires a text box with auto-complete/suggestions (drop down) for multiple words (seperated by a delimiter like space) like the tags text box here in SOF. E.g. I start typing 'app' it should show all words in the suggestions list starting with app, and when I enter a word and press space and start typing a new word it should show all suggestions for that part-word.

Now I want to replace it with an autocomplete textbox, such that when the letter "p" is typed the list shows all three results. It should start matching the first letter of the first word or second word and so on. Also, it should highlight or make the matched letters bold in the suggestions dropdown.Is there a readymade control for ASP.NET (with JS or jQuery) to deliver all the aforementioned functionality? Otherwise if I have to implement it, is there a tutorial/blog which point me in the right direction?
I'm using the AutoComplete function of a TextBox to suggest values from a database to the user. This works almost as expected. However, I do have two questions that I can't seem to find the answer to...
1) Is it possible to change the function that selects the items to display in the AutoComplete dropdown such that it will also select strings that match anywhere else than at the beginning? For example, when I type 'apple' I want that to match 'Apple' but also 'I have an apple!'.
2) Is it possible to change that same function to sort the options? (In my case based on how often they exist in the database.)
i want to make a textbox suggest all possible inputs based on a certain column in my database. for example, i have a country column in the database and i want my textbox to display all countries from my database column that starts with P when i type it and so on

I believe the problem in Mdi form because it has timer code executed after the above code :
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
LblDateAndTime.Text = Now
End Sub
Note: the auto complete code is executed in a child form not in the Mdi Form , what do you suggest to keep suggestions list "sticky" as the user writing in the text box ?

I have a small problem with my AutoComplete Textbox in that it doesn't replace what I type with the item from the drop down list. This is hard to explain so I will start off with the AutoComplete of the combobox and how it works.
If I create a combobox with the following listitems (pay attention to case as this is the actual problem)
Item1
Item2
Production1
Production2
Now I can set my AutocompleteSource to ListItems and when I begin typing into a combobox I get a list of matches (Using SuggestAppend)So if I type i (lowercase) I get a list containing Item1 and Item2 with tem1 added and selected for overtyping in my combobox text. Now if I press Tab or Enter, My combobox.text is updated with Item1 with the proper casing from the list even though I typed a lowercase i. This is not how it is working in the textbox. Using the following code:
Dim mySource As New AutoCompleteStringCollection
mySource.AddRange({"Item1", "Item2", "Production1", "ProductionItem2"})
TextBox1.AutoCompleteCustomSource = mySource
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend
When I begin typing in the textbox, again, the list drops down. And again, when I type a lowercase i, I get a list containing Item1 and Item2 with tem1 filled in to my textbox. Now if I press enter or tab, my textbox is filled with item1 instead of Item1 as it did with the combobox.
My question is:Is there a way to ensure that the text in the textbox matches the actual case of the item in the customsource? I can click the item in the dropdown and it appears in the textbox just fine. But I don't want to force my users to have to do that.
