Ok so if you look at the markup of this page: [URL]
You'll see that it uses eval and unescape to make it look like this in it's markup "%73%65%6c%66%2e%64%6f%63%75%6d%65%6e%74%2e%77%72%69%74%65%6c and so on...."
I'm trying to make a program using httpwebrequest that will grab this long string off the website using regex then decode this and put it in a textbox. I know how to accomplish the first two parts how I could decode this in VB.
I want to execute the code that is passed as a string to my function, the code will be passed at runtime. This is an example code that may be passed as a string to my function. p is a dataset, which is declared and has some values, this code is executed in a asp.net page
p.Tables(0).Rows(0)("disp_status") = "Approved by CEO";
p.Tables(0).Rows(0)("status") = "Approved";
Session("fnc") = "generate po";

I only want to show the credit card info section if the Eval expression evaluates to true, but it gives me and error saying I can only use it in the context of a databinding control, I know I have to put the #, but vb then says that I must use If() or IIF(). What is the correct syntax.

I'm trying to bind an image using Eval() with VB.NET and ASP.NET, but am running into issues:

Is there any way to parse a string in vb.net (like, built in methods), that can do math like Eval can? For example, 3+(7/3.5) as a string would return 2.
I am not asking for you to code this for me, I just want to know if there is a built in way to do this, if there is not I will code it myself.
I can wager that it would not be able to parse stuff like Sin(90) on its own, and I understand that would need to be replaced by Math.Sin(90).
I have a SQLDataSource that is bound to a ListView control but I want to place parts of the bound record into the HTML TITLE attribute. Here is my codebehind file that I want to change so it can use Eval to construct a dynamic TITLE based on the data content[code]...
View 1 RepliesI am working on my first project with the Entity Framework and am having some difficulty displaying advanced information with the EntityDataSource and a ListView.

I've written a piece of software which extracts information from the web and stores it all to a local SQL Server database which all works well. However, I now want to add additional functionality where any user can go in and create a template which would be run when every synch has complete which would save as an HTML file. I've set up whole thing. Information is stored in a backend XML file which is processed when the synch completes. However, I want this information to check delimeters in the string and process it as code.
View 2 RepliesI have a repeater which takes 270 seconds to render and actually ends up crashing all browsers. The SQL to retrieve the data takes about 10 seconds. I wanted to remove the Eval's to see if that speeds up things a bit, but I am having trouble with the correct syntax. I have doubts that this would actually improve performance as I am dealing with 150,000 records. Would a GridView or other control be faster? Would using LINQ to SQL improve performance? Here is the code for the Eval:

View 1 RepliesI need to execute scripted text formulas. I believe that in VB 6 and/or VBA there was a method EVAL() that did the job, eg: [Code] As it seems, such a method does not exist in VB.NET. [url] The method works fine but due to its comprehensive layout its not that fast (as i need to call it myriad of times) Does anyone have a SIMPLE, FAST, straight forward math expression method? Or anyone knows how to use the old EVAL method in VB.NET?

I can bind a inner object property to gridview using the following setup at design time in an ASP.NET gridview
<asp:TemplateField HeaderText="ObjectName" >
<ItemTemplate>
<%# Eval("Object.property")%>

i.e. define my columns, add them to the gridview and then databind
has anyone done this or have any pointers??
this its a very silly problem i have with CheckBoxList control, i dont know if its just me or what but the whole idea of the control its just great but the implementation its very confusing.
im trying to eval something like this
if CheckBoxList.Items.Item(CheckBoxList.Items.Count-1).Checked=true then.....
or something like
CheckBoxList.CheckedItems.Item(CheckBoxList.Items.Count-1) = Checked then...
the problem its that i dont know how does the checkboxlist works but it just sucks that they had to make it so confuising....
i've handled lots and lots of collection controls and they all work in a similar and simple
Is it possible to compare 2 dataitems and then display the result depending on the 2 values using if eval at run time?I have a ListView with databound controls. 1 is RedemptionChoice and the 2 is CashBack.When 1 reads "0" and 2 reads > 0.00 the output should read AUTO I have read many comments online and most point to create a new function within code behind but have found it impossible to implement on my own.I tried this as a test on the actual page:
<%# If(Eval("CashBackRedemptionChoice").Equals("0") & Eval("[CashBack]").Equals("0.00"), "Auto Cashback"))%>
2 needs to be greater than 0.00 for AUTO to be displayed. Hence I know this would not work. Just trying to give an example of what I would like.

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!

View 3 Replieswell until a few day ago. I don't know what I have introduced to cause the problem but now, whenever I load the project, VS 2010 (SP1) crahes. If I delete the project's suo file, the project loads (really quickly) and all is well until I exitVS 2010. When I re-run it and try to load the project, it crashes again unless I delete the suo file.The program can be built for x64 and x86. Now, when I reload the project (after deleting the suo file), it comes up in Debug - Any CPU mode. I can change from Debug to Release and from Any CPU to x86 but if I try and change from x86 to x64, VS 2010 crashes.This is not always the case though. If I build the x86 version and then switch to x64, all is well and I can build the x64 version. Obviously, there's something wonky going on.
