How can I detect if a text is pasted in a textbox (and not typed?)
View 3 RepliesI want my textbox to take only letters as Input, no numbers or other keys.
And Viceversa that I want Only numbers as Input ,no letters or other keys.
I have some textboxes that I only want numbers in and only want a range of numbers to be valid. Also I do not want to use NUDs. I already have the textboxes connected to functons and subs so I do not really want to change them.How would I do this?

View 2 Replieshow do you restrict letters from being entered into a textbox?I know it invloves textbox_TextChanged but i don't know who to do so.
Edit: I figured out that Letters(25) = (a b c etc...) can be used but how to not enter the letter? Uhm.. Like, the user enters "a" and the program recognizes it using an IF statement. How will it NOT enter the letter into the textbox?

View 5 RepliesIs it possible to control the output font that is pasted from the clipboard?
The text copied into the clipboard is from a string variable and does not have any font information tied to it.
I'm wanting to allow users to copy some data and be able to pasted it into what ever they want in a nice format - be it Excel, Outlook Notepad, what ever. Those are the main three I would expect my users to use.
I have the code to populate variables with the HTML string and tab separated values.
If I do:
Clipboard.SetText(TabSeparatedData.ToString)
I have a picture box and if I use Clipboard.SetImage(PictureBox.image) Then I can only paste the image into things like Paint and MS word. I can't paste it as a file into a folder/desktop.So how can I copy the image to to the clipboard and if gets pasted to a folder then it becomes a file?

View 3 Replieshow can I resize it automaticly? For example: I pasted picture which size is 200x200 in RichTextBox and I need to resize it to 100x100.
View 2 RepliesJust like the notepad, it will not allow you to paste any picture in it, and it will convert all formatted text to plain text. It will not change the content of the clipboard, it just like a filter... Is there any way to do it in VB.NET?My program screenshot:
I had a solution in my brain but I think it is not the best... The solution is reformat the text with
richtextbox1.font=myfont after any time I pasted, but it still can paste the other thing like object and picture..
I am wondering how I can select and pull specific bits of data from a block of information a user pastes into a textbox. For example, the information has fixed words and is always in the same format, but the numbers relating to the words may be different. One report might say, for example, Cars: 1.176 and another may say Cars: 863. How do I pull the information about the "cars" from a the block of text with the number value even though it can be different each time?
I must note that there are many many of these scattered throughout the average report and I need to pull the values of each of them in a single click, then paste those values into a different area on the form.
Possible Duplicate: What's the purpose of the Tuple(T1)/Singleton in .net?
Trying to mimic a Tuple as implemented in .Net 4 (For .Net 3) I just realized there is a Tuple(Of T)? This was quite a surprize!
Tuple<string> result = new Tuple<string>("Data");
Instead of this
return "Data";
Isn't the whole point of a tuple that its a container for "loosely related data that isnt cohesive enough to make another class"?
I have a question, i have worked in several languages in my life (including several versions of basic) but i wonder whether in .NET using a variable or equation in a loop is a lot slower than not using one? Take the following identical loops
Dim test(999) As Integer
For count As Integer = 0 to 999
test(count) = count
Next
[Code]...
Now the 2nd case is good because it is easier to adjust the code should the array size need to change yet my background tells me the 1st case is the one in terms of performance, test.Length - 1 is calculated each time the loop runs. a loop of the 2nd kind for example has a massive effect on java as well as VBscript or javascript.So heres the question, would test.Length - 1 be calculated each time the loop ran, or just the first time?
