I ran into a problem. Wrote the following code snippet:
teksti = teksti.Trim()
teksti = Replace(teksti, "<", "& lt;")
teksti = Replace(teksti, ">", "& gt;")
teksti = Replace(teksti, """", "& quot;")
teksti = Replace(teksti, "'", "& #8217;")
[Code]...
After writing this I realized it becomes its own problem. The function is supposed to make information safe for HTML and SQL injection (there are other methods too, parameterized queries, etc but that's beside the point). However what happens, is that it first replaces < with & lt; and then proceeds to replace the newly written string again as every replace string has &, # and ; signs in it.
I thought about using a regex for this, but I couldn't find any decent Visual Basic examples that were simple enough. Edit: I was sure there would be a "smart" easy way to do this, but I guess there are no common methods available after all. The re-arranging the problem cases first is the obvious solution here,As for parametirized queries, checking back I see my English doesn't come out as intended. I meant to say that I'm already using them, that this problem here is specific to prevent all manner of html-injection and possible sql-injection using the same strings elsewhere later.
As you can imagine this causes an error as the two " are not escaped. The issue is " doesn't work either. I imagine this is because Regex has special meanings for such symbols. So my question is should I use the ASCII codes for the the " and the other " ?
Every single time that I want to copy and paste the code that's been color coded, I have to sign into MSDN, choose Insert Code Block, and then Paste my VB.NET Code, choose VB.NET, Click Preview, and Copy and Paste it to an HTML Page, I Want that thing that color codes my VB.NET Code, in order for me to share my work online... I don't want to have to keep comming on here and doing all that just to get the HTML Version of my VB.NET Color Coded CODE..Do you understand what I'm asking...? Where can I get software or HTML that will color code my VB.NET so that I can Copy and Paste it to SeaMonkey's Composer page.
I have to capture the values of the left positions of textboxes in a webpage. I have used the code below but don't know why its not working.
For Each Elem As HtmlElement In webBrowser1.Document.GetElementsByTagName("div").Cast(Of HtmlElement).Where(Function(element) element.GetAttribute("style")) LeftPosition = Elem.GetAttribute("left") Next
Here is some lines of html code for the texboxes:
<div style=position:absolute;top:100px;left:100px> First Name: </div>
I have this string just down loaded of a Unix server. I would like to remove the box (0x0A) Unix end line code; then replace it with CR+LF normal ASCII code. Also, I would like to do the replace before I save the data, while it in memory.
I'm having trouble replacing some HTML strings when they are coming from an database connection and was wondering if you could help.
html = Replace(html, "<ul>", "<ul class=""line"">")
The above line I'm using to replace all <ul> that I pull through with the preferred UL class. Problem is that all tags are coming through as normal.I use the above code to successfully replace the following and was wondering why it wouldn't do the same for <ul>.
html = Replace(html, "<", "<") html = Replace(html, ">", ">")
I have a long string of HTML code that contains several quotes around objects in the string. I have a Regex.Replace() function to change the "img src" tag, due to the way its stored in a database.
Here is my string: <p><strong><u><font color="#cc0099">RICH TEXT BOLD UNDERLINE. PICTURE TO APPEAR BELOW</font></u></strong></p><p><strong><u><font color="#cc0099"/></u></strong></p><p><img src="/inlineimages/WorkOrder/6/1245981403232.jpg"/> </p><p /><p>W00T!</p>
[Code].....
Notice how the "<font color=" has single quotes around its value, and "<img src=" has single quotes, with a double quote jammed in between?
Also, is there an automated way to go from my initial string, to the "Dim input As String" I created? I had to manually type that out, editing the quotes just to try and make it work.
The above will work fine if the html block is spread fully across the keyword.eg.
<b>[CustomerName]</b>
However if the formatting of the keyword is split throughout the word, the string is not found and thus not replaced.e.g.
<b>[Customer</b>Name]
The formatting of the string is out of my control and isn't foolproof. With this in mind what is the best approach to find a keyword within a html string?
Is there any way in VB.NET to remove all of the whitespaces between tags in HTML? Say, I've got this:
<tr> <td>
The string I've built is an entire HTML document, and it counts everything before those tags as legitimate space, so I need to trim it out. Is there a reg ex or function out there I could use to do this?
I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:
± 3 The TextFieldParser is returning ? 3
I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.
Dim lStatementText As String Dim lStatementString As New System.Text.StringBuilder lStatementString.Append(RndRes.Forms.txt_request) lStatementString.Append(" ") lStatementString.Append("<b><a>")
[Code]...
Where Request.ID, Request.Description and also RndRes.Forms.txt_* are all strings. I want to display the string I build up here in a Infragistics FormattedLinkLabel. The problem is that if any of the strigs from the Request class contains a HTML character, the label is not displayed properly and the HTML encoding is broken.I need to find a function that masks the HTML codes.
The sad truth about this post is that I have poor regex skills. I recently came across some code in an old project that I seriously want to do something about. [code]...
I'm working on decoding a NMEA sentence that is a compressed 8-bit string. I'm having a very hard time of wrapping my head around the bit manipulation needed to convert this string. If someone could get me started with this it would be great.
I have some existing code that looks something like this:
[tag:cb cbid="12345" cbwidth="200" cbclassname="calloutbox" cbposition="left"] Lorem ipsum dolor sit amet, consectetur adipiscing elit. [tag:cb cbid="123" cbwidth="200" cbclass="calloutbox2" cbposition="left"] Suspendisse eleifend enim a magna pretium porttitor.
I need to write a VB .Net global function that will match these [tag:cb] and take the optional parameters and rewrite the string with Html tags.
<div id="12345" width="200" class="calloutbox" position="left">content (based on id)</div>
how to replace the html code numbers with the correct ones? i would show you example of html output, but vbforum automatically converts the characters so no point. i wish the replace all the & #40; (without the space) and so on with their correct replacement eg, ( in this case. also would like a short way to do this as i will be using this multiple times. so basically i would like the source to be exactly as it would if you viewed source in firefox browser, not with all the special chars unformatted like visual studio does.
I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?
So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td> <input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden"> <img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work"> </td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public Sub Main() Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate As String
I'm working on a timekeeping application in Visual Basic 2008 and am having trouble formatting a timespan for display. Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?
I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString") Private _myObjectLongName As New ThisObjectLongName("SomeString")
I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
