I want get the most specific from the current url in visual basic .net.
I've tried several code but it just was the same.
I have this code:
Dim CurrentURL1 As String = Request.Url.PathAndQuery
The code will result like: /FolderName/CurrentUrl.aspx
What I want is, just get the 'CurrentUrl.aspx'.
How to get that?
Have you tried Path.GetFilename ?

Actually, I think you can use the Uri class, the class is better suited for your needs. It has several properties you can use to get what you want.

I am integrating with a system that creates part of a URL and I supply part of the URL.
I supply this:
http://myServer/gis/default.aspx?MAP_NAME=myMap
The system supplies this:
?type=mrolls&rolls='123','456'
(the "rolls" change depending on what the user chooses in the system)
so, my URL ends up looking like this:
http://myServer/gis/default.aspx?MAP_NAME=myMap?type=mrolls&rolls='123','456'
I need to get the rolls but when I try this in VB.Net:
Dim URL_ROLL As String = Request.QueryString("rolls")
I get an incorrect syntax error.
I think it's a combination of the 2nd question mark and the single quotes.
When the system is only passing one roll, it works, I can get the rolls from the URL
which looks like this:
http://myServer/gis/default.aspx?MAP_NAME=myMap?type=roll&roll=123
I asked them to change the format of the system's URL but they can't change it without affecting the rest of their users.
Can anyone give me some ideas on how to get the rolls from the URL with single quotes?
OK, I believe I've fixed my problem.
I used a regular expression to remove anything in the querystring that wasn't a number or a comma.
Thanks again for taking time to make your comments, it made me look at the problem from a different angle.
I have implemented a routing functionality successfully in my project (a news website):
Sub RegisterRoutes(ByVal routes As RouteCollection)
routes.MapPageRoute("ndetails", "news/{title}/{id}/", "~/newsdetail.aspx")
End Sub
and I set the URLs like this (databound to a repeater):
href="<%# Page.GetRouteUrl("ndetails", new with { .title= Server.UrlEncode(Eval("Title")), .id= Eval("NewsID")})%>"
The URL produced is like:
/this%20is%20a%20news%20item/89
As can be seen above, the URL part is difficult to read and I would like it to be like:
/this_is_a_news_item/89
I thought of going for a Replace function. But then, since the user creating the news might enter any string, I have to take into account all the other characters that might need to be replaced.
I just wanted to know from an experienced developer, whether going with a long replace function is the way to go, or is there another solution to format my URLs in this rouitng scenario.
Many thanks in advance
AFAIK there is no built in funcitonality in the framework to make url "pretty". You have to implement your own url fo rewriting the title.
In the save of your entities simply use a function that do the replaces that you need (' ' with '_' or example) and then use UrlEncode.
You can also use a Regular expression to do the replacement in one go.
i was used with php to use printf to build my strings, but i cannot find anything similar with asp and i end up writing crap like:
WrapTag="<"&Tag&">"&Text&" </"&Tag&">"
instead i would liek to write something more readable, like:
WrapTag=String.Format("<{0}>{1}</{2}>",Tag,Text,Tag)
as it was shown with this url:
http://idunno.org/archive/2004/07/14/122.aspx but it is not working.
Can anyone help me on that?
The code that you show is correct.
You don't have to send in the tag name twice, you can use the same value twice in the format:
WrapTag = String.Format("<{0}>{1}</{0}>",Tag,Text)
I have one issues I'm struggling with with regards to my HTTPModule filter:
1) I notice that the module gets it's data in chunks. This is problematic for me because I'm using a regex to find and replace. If I get a partial match in one chunk and the rest of the match in the second, it will not work. Is there any way to get the entire response before I do my thing to it? I have seen code where it appends data to a string builder until it uses a matches on an "" end tag but my code must work for more that just (xml, custom tags, etc). I don't know how to detect the End Of Stream or if that is even possible.
I am attaching the filter in the BeginRequest.
Have a look at this example. It looks for "" in the stream of the page.
Here's a sample project which performs buffered search and replace in an HttpModule using a Request.Filter and Response.Filter. You should be able to adapt this technique to perform a Regex easily.

Apologies if this seems like a duplicate post...
Thomas Warner kindly answeres an earlier post suggesting I use:
Popup.aspx?Data1=Piece_of_data&Data2=Piece_of_data
Just want to ask, if my code is Popup.aspx?Data1=textbox1.text&Data2=textbox2.text
whats the proper way to reference whats in the textboxes?
The way is is above, all that appears in the popup is the actual text 'textbox1.text'
rather than what is actualy in that control.
thanks again
Using asp.net you can litterally write the value straight into the string like:
Popup.aspx?Data1=<%=textbox1.Text%>&Data2=<%=textbox1.Text%>
A more ideal way of doing this would be to build up the URL string in your codebehind so as not to clutter up your HTML and C# code.
That way you could do something like:
String popupUrl = String.Format("Popup.aspx?Data1={0}&Data2={1}",
textbox1.Text,textbox2.Text);
This will also allow you to do any sanitization checks on the values from the textboxes before you start passing those values around.
