I've got to generate html files with text data containing > < " and other punctuation and special characters. I 'manually' replace them with < > and " and I wonder can it be done using some .Net Framework class?
Also I'll be interested in 'unescaping' such sequences back to characters.
I have a block of HTML which I want to write to a file. It contains about 30 lines and it's difficult to escape all the double-quotes in individual WriteLine statements. In PERL, I can do something like the following to write inline HTML and print everything upto <<OUTFILE to outfile as-is, is that possible in VB .Net 2008?
print <OUTFILE <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD><TITLE>GSC Signature</TITLE> <META content="text/html; charset=windows-1252" http-equiv=Content-Type> <META name=GENERATOR content="MSHTML 9.00.7930.16406"></HEAD> <BODY><<OUTFILE
I could save the HTML in a template file and copy it into a new file each time, but that's not very flexible.
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?
I have a dropdown where the items initially are filtered (using a SQL Datasource) based on the selection of another dropdown; however, I have included a checkbox where if checked, the dropdown needs to populate with all data from another datasource How do I programatically remove a datasource that is bound to a control and then define another?
I have the following code, but it errors: If cbOverrideArea.Checked Then Me.ddArea.Items.Clear()
I have a goal to have dropdowns populate using a string array as the datasource. Re-binding works well in the dropdown event, but if I make a change to a currently selected line item it won't change until I make the box dropdown again. Is there a way to keep this updated without re-binding the data?
Also, this is one of several dropdowns on an MDI child form. I'd like to make sure they're all synced. For instance if one has "Bob" selected and I change Bob's name to "Chris" I need all the "Bob" dropdowns to change to "Chris". Is there a way to do that without having to cycle through all the windows and call a rebind function?
Finally, I want to know if there's a better way to do it than the way I'm doing it. Since all these children have to be synced, the MDI parent holds the String array as a public property and the children each leech off of it.
I gather MATTER NUMBER and PATENT NUMBERS in a listbox on a dialog form - that I pass to the main form after the dialog closes.I then ask for CASES on subsequent dialog forms and want to have drop downs for MATTER NUMBER and PATENT NUMBERS that "have the suggestions" of what was entered in those list boxes earlier.So - I've been using DATASOURCE for binding to datatables and thought to myself - heh - I can probably set the DATASOURCE of the DROPDOWNS - and it works!
Public AddMatterNumber As ListBox Public AddPatentApp As ListBox MatterNumber.DataS
I'm trying to make my datagrids datasource change when you select a particular item from a drop down menu but all I get is blank cells! any ideas? I don't think it is changing the colums property automatically either.
If chooseType.Text = "Add / Edit Players" Then updateDB.DataSource = PlayersBindingSource
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
the coding is to 'Get input string and put its character into List, and replace the character with other.'but having problem putting each character into List and also replacing it,[code]
I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String) Dim returnList As List(Of String) = New List(Of String) For Each inputString As String In inputList returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.
Im trying to autofill a html form and all textboxes and textarea is working ok.. I now have a problem with a combobox1.I added the items below to the combobox1. So whenever i choose one of those items it needs to choose the same value on the website dropdownbox.[code]
So the background on this question is this. We have a couple of applications that communicate with each other and with client's applications through sockets. These socket messages contain non printable characters (e.g. chr(0)) which need to get replaced with a predetermined string (e.g "{Nul}"} because the socket messages are kept in a log file. On a side note, not every log message will need to have characters replaced.
Now I started off on this little adventure reading from This MSDN link which I found from a different post from this site.
The current method we used...at the beginning of the day...was using string builder to check for all the possible replacements such as...
Public Function ReplaceSB(ByVal p_Message As String) As String Dim sb As New System.Text.StringBuilder(p_Message) sb.Replace(Chr(0), "{NUL}")
[Code]....
This so far has been the fastest way I have found to process these messages. I have tried various other ways of going about this as well like converting the incoming string into a character array and comparing along with also trying to loop through the string rather than the chrArray.
I am trying to call a fortran DLL from VB.NET. Fortran function requires two character strings to be passed from VB to fortran. I am able to run the code with a change after receiveing a AccessViolationException error. I dont understand why it worked can some one whose professional explain me the difference. Here I am attaching the codes for reference
So I have software to replace string with string, it's cool but I need code which would replace any given character (for example a) with all strings from textbox.
I am using a CheckBoxList in a VB.NET web project. The elements are pulled from a DataSource which is populated elsewhere in the system.
The problem is, if someone put in some raw HTML, the CheckBoxList seems to render it rather than assume plain text.
In this screenshot, for example, I entered <a href="http://www.google.com" onmouseover="alert('123');">hover here</a> so now whenever you hover over that CheckBox, an alert window pops up. This seems like a potential for XSS and I would like to disable it altogether.
I have tried googling and searching SO for someway to disable HTML rendering such as this, but haven't found anything relevant, so my apologies if this already has been answered elsewhere.
I need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this:
Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String 'Create a new StrinBuilder that would hold the random string. Dim randomString As New StringBuilder
[Code]....
What is going on? I thought that I used to, a long time ago, be able to just do random.Next.
I had a strange error in a VB6 app this morning and it all stems from the fact that IsNumeric is not working as I expected. To me this seems like a bug.
This code displays 4.15877E+62 in a message box:
Dim strMessage As String strMessage = "0415877D57" If IsNumeric(strMessage) Then
[Code]....
I am guessing that the runtime engine is incorrectly thinking that the D is in fact an E? I think this is a bug though as the exact same code in VB.NET outputs not numeric Is this a known issue with IsNumeric?
I have quite a bit of VB6 experience but now am trying to create my first VB.Net project. The project is very simple - it just needs to send 8-10 character strings from the PC serial port. The problem I'm seeing is that VB.Net is always sending out a 0x0A character after each 'WriteLine' call. Using VB6 it was necessary to manually send out any End Of Line characters. My application requires that no extra EOL characters be sent after the string.
I am working on a program to connect to a site by using httpwebrequest methood. I want to know how to get the html tag using with httpwebrequest? The html tag I want to grab the data from the page to input in the listview is:
<p id='myid'></p><p id='myid'>The name of the data</p>
Here's the full code:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Address of URL Dim URL As String = "http://www.mysite.com/" Dim request As HttpWebRequest = CType(WebRequest.Create(URL), HttpWebRequest)
I've inherited a VB website (I'm a C# developer by trade) and need to do some changes. On loading it into VS2010 it won't compile/run because it has a <!-- --> pair surrounding some code in the style section of each form and VS is saying this is an unexpected character sequence.I'm assuming it's a vb comment tag, but I've Googled it to with either making VS accept them, or advice on what to change them to so the original intent is not lost. NB I've tried <%-- which I use in C# but that doesn't appear to work either.
I am working on my application that I am reading the strings through html page using with httprequest. All I am trying to achieve by find the value using with the matches which come next equals, something is like: "Address=Whateveritgoeshere". So I want to extract to get the strings which it would be: "Whateveritgoeshere"
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Address of URL Dim URL As String = "http://mysite.com/getInfo.asp?id=" & Textbox1.Text
[code]....
However when I deug to run the application, I have got an empty returned strings. Do you know why I have got an empty returned strings?If you think that I have done something wrong then how I can only extract the strings that come next to the "Address="?
How can i make a dropdown list with checkboxes ? I have a windows app ( vb.net) and the checkboxlist control is not real an option with the available space on my form.
I have a web form in which i have droped 6 dropdownlists and each dropdownlist have previous seven dates to open files from a specific folder concatenated with date at the end of file name.Problem is that when i select first dropdown list it opens file fine but when i select a date from anyother dropdownlist to open file then it open the same file which was opened from the first dropdownlist.Please see the code and make correction in it.
