Nov 24, 2011Just 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..
Displaying All Text On One Line When User Clicks Button
Apr 4, 2012I am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email,
email,
email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.

View 2 RepliesFCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text
Dec 19, 2008I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Dec 10, 2011My single-instance application has code to auto-start from the command line and open a requesting file with the appropriate extension when it's double-clicked or 'run' - this works fine. Once it's up and running however, what is the recognised way to detect a command line request to open another similar file so I can offer an option box to stay with the existing file or close it and swap to the new one? Can I do this within the main app, or do I need some sort of 'background listening' app to detect this and act accordingly?

Detect If User Presses F Key?
Feb 17, 2011I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress

Detect User Country From IP?
Mar 24, 2009Dim hostname As IPHostEntry = Dns.GetHostEntry(TextBoxIP.Text)
Dim ip As IPAddress() = hostname.AddressList
TextBoxIP.Text = ip(0).ToString()
I have a windows form with the code above to get the ip address of the user. what would be the easiest way to get the country location of the user? based on the IP in the textbox. The solution doesnt need to be 100% accurate but good enough to work most of the time. the simpler the better.is there are any work arounds or built in fuctions for pulling a users country or language, this would be better than creating or managing a giant database.

View 1 RepliesDetect User Choice During Run Time?
Sep 10, 2010No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).
I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?

View 22 RepliesParsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?
Feb 7, 2011a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

However, as soon as the user presses CTRL-ALT-DEL the Windows Security Screen comes up and it is too fast for VB to detect that the keys have been pressed.I did a little reaserch on how to work around this issue and found that a GINA stub can be written which can delay the Windows Security Screen by some time say 2 secs which would be enough for VB to detect that the keys have been pressed.Also disabling Ctrl-Alt-Del through VB does not work because it is too fast for VB and I would like not to disable CTRL-ALT-DEL
