Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:
Try dbConn.Open() Catch ex As Exception errmsg = ex.Message End Try
I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.
Basically what i am trying to do is display a list of categories. And if the admin is logged in i want to show some buttons next to each category. For example a button to delete it. The problem is that i dont know how to pass a parameter to the function that does the action.Like i specify that on button click the function 'DeleteCat' must be called but if i cant pass the ID of the category to be deleted this wont work.I know this can be done with commands and a repeater, but its not an option, i cant use a repeater.So apparanly this is what i am aiming for:
I have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :
[code]...
As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.
I have menu item on my master page that has block around the text when the page is first run. I wrote in the css on the link and visited property to change the color to match the image color that it is on. When a menu item is clicked the color changes to the right color. How do I get it to the right color on when the page first opens or is there a way to get rid of the block or make it transperant?
I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place? <p> <%for (int i = 0; i < 30; i++) {
Im stuck with declaring a string which is in a loop within another loop.
Dim CompanyDetails As String = "" Dim CompanyRow As DataRow For Each CompanyRow In newdt.Rows CompanyDetails += CompanyRow(1) & " " & CompanyRow(0) & "<br/>"...
How can I get this to see the GetInfo as declared..... since its in a loop within a loop?
where I show a link if value>0 .. However it gives me a bad url(history.aspx?visitorid=%3C%#%20Eval) when I put visitorID=<%#...%>inside another Eval<%#..%>
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column. Anyone know the right syntax, keep getting object not set to reference. I'm doing this in VB.Net.
i have users who can logon to my site. I don't use the asp.net provider (i have my own user storage) but do use forms authentication. No i want to block users from log on twice to my app. Now what is the simplest thing to accomplish this? I thought about an extra field in the database in the user record but is there something simpler? is there a sort of 'session' for the entire application where i can remember who is logged on (and which is not flushed at a random time)? maybe in the cache (but the cache is sometimes flushed) i've seen an example where a file with the username was written to disk (and removed when logged out)
EDIT: Good question was: what do you mean with logon twice. I mean when a user logs on on another computer or when another person logs on with the same credentials
I intend to around existing code snippet (updating a Hashtable) with lock() block to prevent multiple threads (launched by ASP.NET web site) from simultaneously updating a Hashtable.
Bc this is first time I do in this measure, I need your advice on
Any performance overhead caution caused by lock() Any other issues you ever experienced similar to this scenarios.
I have a simple wcf service like this, with a test method which simply sleeps for 20 seconds and returns a value. I wrote a test page which uses jquery to call it 10 times in a row, and it appears to execute concurrently, with the client waiting 20 seconds and then getting results back from all of the services at about the same time.
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall,ConcurrencyMode=ConcurrencyMode.Multiple,UseSynchronizationContext=false)] public class AjaxTestWCFService : IAjaxTestWCFService
However if I set
aspNetCompatibilityEnabled="true"
in web.config then no matter what I do, with concurrencymode, usesynchronizationcontext or instance context mode, or even serviceThrottling config, it appears to execute each web service call sequentially, with it taking 2 minutes for all 10 requests to return!!
Now I realize that this may be because of session, but at least in ASMX services I was able to set enablesession to false. And in fact my web service method is not using session at all. So you may wonder, why use aspNetCompatibilityEnabled at all. Because I want to use ASP.net impersonation and forms authentication.
I'm using asp.net membership provider. and I need to block user account in case if the user post spam. How can I accomplish it using build in features of the Membership Provider.Can I use IsLockedOut? If so how can i update it programmatically?
if you have two table inner join like SELECT* From A INNER JOIN B on A.ID = B.IDSay A and B tables both have Username values but A's username is Test, and B's username is Test2When I do Eval("Username") it always print out "Test", how can I configure it to print out "Test2"... meaning how to specify which table's value to put using eval.. is there something like Eval(B.("Username"))??
What I am trying to achieve is to use an Eval as parameter in my anchor tag's href. The anchor is nested inside a repeater, why I cannot use the code behind to achieve this.
