View 9 RepliesI have successfully been able to parse HTML from a website:
TestParser parser = new TestParser [URL]
List<Pairing> pairings = parser.ParsePairings();
DBSave.SavePairings(pairings, userID);
----------
This works. Now I have to submit a form via C# code.... DONE. It works. And my C# code saves the "new" HTML to a string variable called "submitParsedHTML". My question is: how to I change out the URL, to go through the string variable instead? I am thinking about doing this: When the user clicks the button to "Post" to the form and the app grabs the HTML. The app logs into my FTP account and saves the HTML as a seperate (temporary) file to be used on the internet [URL] Then the app can then parse the HTML as if it was a normal HTML document and not have to go through formatting the text to an HTML document. What do you all think?
I want to create a link button with following code. However, this linkbutton doesnt work correctly: when I clicked it, it cannot go to the target url and will cause an exception.
<asp:LinkButton PostBackUrl='LearnPage.aspx?cid=<%#Eval("cid") %>' runat="server"><%# Eval("cname")%></asp:LinkButton>
(The linkbutton is one column of a grid view)
Debugging the code, I found that the value of cid is not parsed to the url. Actually, this code <%#Eval("cid") %> is not recognized as a variable, the target url appears to be LearnPage.aspx?cid=<%# Eval("cid") %> instead of LearnPage.aspx?cid=VALUE.
I need to accomplish a simple task like this:
1. Assigning text of a few lables to corresponding variables.
2. Taking/posting these variables to server and process them.
3. Print the outcome in a message.
An example would be: Take lable1 as variable x. Take lable2 as variable y. then process as z=x+y. and print z on the page.
Given a string like:
Token A^*!%~Token B^*!%~Token C^*!%~Token D^*!%~Token E
Write a method that parses the string into a series of substrings where the delimiter between the substrings is ^*!%~ and then reassembles the strings and delimiters into a single new string where each of the substrings is in the reverse order from the original string. The method must return the final string. The expected output would be:
Token E^*!%~Token D^*!%~Token C^*!%~Token B^*!%~Token A

View 1 RepliesI have a String that contains the following: ?workarea=London+&+Home+Counties+Ltd&sub=fs&&&FASh*5which resembles a URI query string. What is the best way to parse the elements of this string (workarea and sub) without messing about with string manipulation?If I use HttpUtility.ParseQueryString is gets stuck as both elements include &. However if I encode the whole thing first I lose the seperations of the elements. Ideally the output would be:workarea = London & Home Counties Ltdsub = fs&&&FASh*5
View 4 RepliesIs there a way to easily split a comma delimited string into variables (or table fields), example:
PHP Code:Feed.SmulocV2.Equipment,CAT,,DFT08783,2567,Hours,2010-02-07 06:37:41,Lat:38.025921,Lng:-88.776733

View 1 RepliesIf I have a file in a path lke this:
C:demo estfile.txt
I can a split function and split on the backslash character to get the pieces. But if my directory could change this wouldn't work. So how would I instead parse out the last backslash and get the filename that way so that it wouldn't matter if the path changed?

View 1 RepliesI have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

Meas var x will replace at the place of Lead_ID
Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.
The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....
Object variable or With block variable not set.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object variable or With block variable not set.

Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
Line 122: End If
I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:
*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)
*If Not localLblItemReference Is Nothing Then

To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.
In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:
