I'm writing a program that get's all movie info from imdb via the sourcecode of the webpage.Now I encouter the problem that when I store certain values in a string some special chars are stored as for example 'Of course when I display my movieInfo I don't want to see Amelia's Boyfriend but Amelia's Boyfriend (also, is it best to store the special chars as ' in a database and convert them after the query, or is it beter to store the string as ...Amelia's...
I solved this issue in this thread but there still are issues with special chars. ie 'I thought by doing parameters that it would take care of any special chars for you. Well i am still getting mysql exceptions about syntax. I look at the string it is working with and it has a "'" in it.Why are they not working as I expect them to?
I'm using this code to read through each line in a textfile, and remove all that starts with a spesific "searchword":[code]But there are chars in the original textfile, that don't display the same in the new file.
I have a database where the data contains some special chars. I retrive the data from the dbase (dbf) file with a sql statement and write it into a text file using vb.net. When I write the text file some of the special characters are not written the same way as in the dbf file, its written as a box. I'm using:
Using sw As StreamWriter = New StreamWriter(dbfFile, False, System.Text.Encoding.Default)
while writing to text file. I'm not sure how to read the exact data from the database.
I'm not sure what to call this so my search results weren't very helpful. I am writing an XML document that has computer paths and special chars such as '&'. XML does not like them, so I need to find a way to convert them. I looked at Apple's iTunes XML document and they have the following:Actions & Motives = Actions '&' Motives (without the ' ')C:/Documents and Settings/mmulhearn/My Music/iTunes = C:/Documents%20and%20Settings/mmulhearn/My%20Documents/My%20Music/iTunes/
I am a new VB programmer and am using TextBox in VB2008. Here are the problems I experienced in TextBox -
1, After I typed number in TextBox and found I need to type another number. So I used backspace key to remove it. But at this time program quit and displayed this problem: InvalidCastException was unhandled. How to solve this issue?
2, Can anybody tell me how to set number of characters are allowed to be typed in TextBox?
3, Can anybody tell me how to implement the feature that only numbers are allowed to be typed? In case letters are typed, how to tell user to re-type?
I am trying to export some data from a SQL Express table to Access using VB.net. The data is correctly displayed in SQL as, for example, temperature with the small degree object and the letters F or C for Farenhiet or Celsius. The character is of course represented by ° = "°" in html code, which is what appears in my access tables.
How can I get the insert statements to correctly pass this symbol? I have thousands of records and this applies to maybe a hundred or so in each of a few hundred DB's I am running this conversion on.I read the data from a Gridview an .aspx .net web page and then use an insert query with an Access OLEDB connection.
I wrote my own database handling code (actually, I write T4 text templating files that generate my database code for me) and part of it takes care of converting values from a database (as Objects) to the desired types.
I have been using this generic function successfully:
vb.net Public Overridable Function ConvertType(Of T)(value As Object) As T Try Return If(value IsNot Nothing AndAlso value <> DBNull.Value, DirectCast(value, T), Nothing)
[Code]....
Simple enough, but it doesn't work... The return type of the function is (and must be) T, so I cannot return a Boolean because a Boolean cannot be converted to T!
Well... It can in this case, because I specifically check that T is Boolean, but the compiler doesn't know this so it doesn't allow me to return a Boolean. I cannot cast the boolean to T either.

I've received a text file in which the text is like this, ãYAHOO.COM. When I'm debugging in Visual Studio, the value I see for the character is "�"c. Firstly can anyone tell what is the character before yahoo. Is it a special character or some html character, and what is the character that I'm seeing in VS while debugging.So it goes like this, the ascii value of the character turns out to be 63.But when I write the value to a file it generates 3 characters whose ascii values are above 127.
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?
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
We receive an HTML document in an email which has some special pricing and products. I want to be able to parse the data, perform some lookup operations on it, assign some pricing markups, save it to a data source for future referance and do it with VB.net and a web browser. I'd really like to use MSHTML.HTMLDocument, but all the documentation I have is based on HTTP URL's, but since these HTML pages will be opened from an eMail or saved to a fileshare, they won't have the HTTP. I've also tried to read it as a text file and parse with RegEx, but it's not very effecient and to be honest, RegEx is still a fog to me.
Would anyone be kind enough to suggest a way to do this? Is MSHTML able to do it and if so; how do I set up a reference to a non-HTTP URL?
I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
I'm trying to ensure that all characters which are not numeric, or alphabetic are converted to HTML code when submitted to my database.
[Code]...
This successfully converts anything to HTML, but now I need to put some condition in there so it only does it where I need it to. ie; on any character which will either screw up my database entry, or screw up formatting when returned back to the screen as HTML (this database content is for product data for a website).
So for simplicity, I guess I want to convert only charcters which are not A-Z alphabetic or 1-0 numeric.
I could use isNumeric, but not sure how to detect alphabetic characters.
I've been Googling and found something which looked like it would work, but the logic/filtering was wrong.
In SQL I had to alias my column header with some text containing special character, So to mask these characters {}, I had to keep them in double qoutes. eg: select column1 as "{Ctrix}" from table; When ran in sql the result is
{Ctrix} ------- 1
2
3
The problem that I got was while passing the same above query in the code that I had written in VB.strSQL="select column1 as "{Ctrix}" from table;" The query is getting truncated and giving error. Please help me, how to handle this properly at sql/vb... which satisfies both.
I am busy with trying to convert data from an application so that it can be shown in HTML form via websites. I need to make a tree wherein I have 3 main categories each with their own sub-categories. These are the categories/sub-categories.
but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events! better way to replace the html with suitable asp.net web controls or from the codebehind and output it.
