VS 2010 : Do 'Something' If Richtextbox1.text.Is A URL = True
Mar 16, 2012
Basically I want a piece of code that will only do something if richtextbox1s text is a url. Here is a MOCK code.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If richtextbox1.text.containsURL = True Then
webbrowser1.navigate(richtextbox1.text)
End If
End Sub
I'm using Visual Basic 2005 Express Edition and I was just wondering if someone could help me out with a few things? I'm making a Notepad-type program just to clarify things.1. I have a button which adds text to my RichTextBox1 (excuse the name), but when you click it it adds text to the end of the script. I want to make it so the text is added where your "cursor" (the blinking thing which lets you know where you're typing) is, at the current part of RichTextBox1. At the moment I'm using:
RichTextBox1.Text = RichTextBox1.Text + "The text I'm adding" If anyone could tell me the code to make it put "The text I'm adding" at your current cursor that'd be great.
2. I have a Save As button and a Save button. When you click Save As and save the file it works 100%, when you click Save and you haven't saved previously then it works 100%, but after you have saved the file and then click save it doesn't overwrite the file. Here's the code for Save:
[code]...
So if anyone can tell me the code that's needed so it will overwrite the current file 3. I have a FontDialog but I have no idea what the code is supposed to be to make RichTextBox1's font change after you click Okay in the FontDialog.
Text displayed by the RichTextBox1 is too big. It creates vertical and horizontal scroll bars. It there any way to zoom in and out to make the text fit as one desires?
i am programming a note and i save the plain text of the richtextbox1 to a notepad then i want to print it i use this code but it print the frist line only and i want to print all lines Private Sub SaveToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripMenuItem1.Click
I have an email creator that needs to extract the emails created from the html page, display the accounts in a richtextbox1 & then save the accounts as a .txt file on my system. How would I go about doing this? Doe anyone have a great code sample??

I need to use the character height of a lowercase character. I have tried using MeasureString, but that gives me the same number for both uppercase and lowercase characters. That is not acceptable. How do I get the true height of a character?
I'm having some issues with parsing a lot of information into controls using winforms. I've tried adding threads/backgroundworkers, but they don't seem to work properly. To avoid the cross-thread exception, I had to add an invocation checker:If Me.InvokeRequired Then Me.Invoke(New MethodInvoker(AddressOf ParseSub()))This just freezes the form as it would without threading, but without the invoke checker I get cross thread exceptions because information from one thread is trying to be sent to another.
I made 'quiz' form: 1 question/label and 3 answers/radio buttons, next and previous buttons.Data is from data set. One question and 3 answers are in one row. After next button is clicked, new row is loaded. The problem is when click 'previous' button: instead of text from data base, checked radio button text is 'True'. The same is when the quiz is completed and I want to review mistakes.
I want to have a text file perhaps a ini file where I want to set a value to either True or False so a boolean. How can I do something like this. I want it to be a in text file so I can change. If it's in settings I'll need to change each users settings I want each user's application to read this text file.
I have made a own namespace, with some classes and subs. One sub looks like this: ffmpeg.SetEnc.x264 And there it does something. How can I make a sub which I can set as True/False, like this: ffmpeg.Extras.Overwrite = False/True
I have a serial port hub with 4 ports. 2 of them work perfectly and the other 2 don't.I've found out that the 2 that don't work always have CTS, CD, and DSR on/true.The 2 ports "don't work" because they aren't able to receive a response.How can I turn off CTS, CD, and DSR holding? It seems that they are ReadOnly properties.I don't know if this will help, but I've recorded a log (recorded pin values every 1 second interval) for one port that worked and another that didn't.The one that didn't work:
As you can see, the one that doesn't work has a value of 1 in CTS, DSR, and CD at all times. Also, the one that does work was able to receive the data, which is shown by the 14.
I brought up a new project in Visual Studio 2010 and found that there are no gridlines on the form. I went to Tools, Options, Windows Form Designer, General and found the Show Gridlines option set to True. I tried turning it to false and back to true with no change.

I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
I'm trying to create a quick little program in VB 2008 that can parse extract the google search results based on the search criteria of the user input.
Basically what I have is a textbox1.text that enters the keywords into google, google will then put the url results back into my richtextbox1.text.
Here is the code that I have:
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted Me.Text = WebBrowser1.Url.AbsoluteUri
