  • Get Confirm value in vb.net

    - by user1805641
    I have a hidden asp Button in a Repeater. In the VB.NET code behind I use the Rerpeater_ItemCommand to get the click event within the Repeater. There's a check if user is already recording a project. If yes and he wants to start a new one, a confirm box should appear asking "Are you sure?" How can I access the click value from confirm? <asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand"> <ItemTemplate> <div class="tile user_view user_<%# Eval("employeeName") %>"> <div class="tilesheight"></div> <div class="element"> <asp:Button ID="Button1" CssClass="hiddenbutton" runat="server" /> Index: <asp:Label ID="Label1" runat="server" Text='<%# Eval("index") %>' /><br /> <hr class="hr" /> customer: <asp:Label ID="CustomerLabel" runat="server" Text='<%# Eval("customer") %>' /><br /> <hr class ="hr" /> order: <asp:Label ID="OrderNoLabel" runat="server" Text='<%# Eval("orderNo") %>' /><br /> <asp:Label ID="DescriptionLabel" runat="server" Text='<%# Eval("description") %>' /><br /> <hr class="hr" /> </div> </div> </ItemTemplate> </asp:Repeater> code behind: If empRecs.Contains(projects.Item(index.Text).employeeID) Then 'Catch index of recording order i = empRecs.IndexOf(projects.Item(index.Text).employeeID) Page.ClientScript.RegisterStartupScript(Me.GetType, "confirm", "confirm('Order " & empRecs(i + 2) & " already recording. Would you like to start a new one?')",True) 'If users clicks ok insertData() End If Other solutions are using the Click Event and a hidden field. But the problem is, I don't want the confirmbox to appear every time the button is clicked. Only when empRecs conatins an employee. Thanks for helping

  • wpf mvvm datagrid selectedrow

    - by 2Fast4YouBR
    Hi, after some google around, I just figured out that there is no one that is using 100% MvvM pattern to get the ToolKit DataGrid events ! Is that impossible or what ? I see too much people using the code-behind... How can I get the SelectedRow or dblClick events using mvvm ? cheers

  • Vector iterators in for loops, return statements, warning, c++

    - by Crystal
    Had 3 questions regarding a hw assignment for C++. The goal was to create a simple palindrome method. Here is my template for that: #ifndef PALINDROME_H #define PALINDROME_H #include <vector> #include <iostream> #include <cmath> template <class T> static bool palindrome(const std::vector<T> &input) { std::vector<T>::const_iterator it = input.begin(); std::vector<T>::const_reverse_iterator rit = input.rbegin(); for (int i = 0; i < input.size()/2; i++, it++, rit++) { if (!(*it == *rit)) { return false; } } return true; } template <class T> static void showVector(const std::vector<T> &input) { for (std::vector<T>::const_iterator it = input.begin(); it != input.end(); it++) { std::cout << *it << " "; } } #endif Regarding the above code, can you have more than one iterator declared in the first part of the for loop? I tried defining both the "it" and "rit" in the palindrome() method, and I kept on getting an error about needing a "," before rit. But when I cut and paste outside the for loop, no errors from the compiler. (I'm using VS 2008). Second question, I pretty much just brain farted on this one. But is the way I have my return statements in the palindrome() method ok? In my head, I think it works like, once the *it and *rit do not equal each other, then the function returns false, and the method exits at this point. Otherwise if it goes all the way through the for loop, then it returns true at the end. I totally brain farted on how return statements work in if blocks and I tried looking up a good example in my book and I couldn't find one. Finally, I get this warnings: \palindrome.h(14) : warning C4018: '<' : signed/unsigned mismatch Now is that because I run my for loop until (i < input.size()/2) and the compiler is telling me that input can be negative? Thanks!

  • google app engine proxy workaround

    - by Lumpy
    I am trying to build a google app engine app in Java. The app is trying to get information from another site. On my computer I am behind a firewall and need to connect to the site through a proxy. Google app engine does not allow the use of java.net.proxy. Is there a way to configure eclipse so it knows that when I use URL.getContent() my local host will connect to that url through a proxy??

  • Detect use of older Java libraries

    - by Tony Morris
    Is there a third party library to detect the use of a Java 1.5 library when compiling with a 1.5 compiler with -source 1.4 and -target 1.4? I could use a 1.4 rt.jar in the bootclasspath however I hope there is a better way. To be used, for example, to fail the compile/build if a newer library is used.

  • Z-index issues in IE8 while using 960 grid

    - by Shane Reustle
    I am having an issue in IE8 where my dropdown-style navigation is going behind another element. I have tried everything from setting the offending element's zindex to 1 and the dropdown to 99 and 999. I think it has something to do with the fact that I'm using 960 grid, as it worked before when I wasn't. Update: Problem occurs in IE8.0.6 but not IE8.0.7 Here is my stylesheet and you can see the issue happening here

  • Objective C: Class Extensions and Protocol Conformation Warnings

    - by Ben Reeves
    I have a large class, which I have divided into several different class extension files for readability. @protocol MyProtocol @required -(void)required; @end @interface MyClass : NSObject <MyProtocol> @end @interface MyClass (RequiredExtension) -(void)required; @end Is there a better way to do this, without the compiler warning? warning: class 'MyClass' does not fully implement the 'MyProtocol' protocol

    I was trying to inherit from QGraphicsEllipseItem 'cause i wanted to add some functionality to it. However i was faced with this error, which probably has something to do with the compiler/precompiler or moc? error: 'staticMetaObject' is not a member of 'QGraphicsEllipseItem' And here's the class code: class MyEllipseItem : public QGraphicsEllipseItem { Q_OBJECT public: MyEllipseItem (const QRectF & outline) : QGraphicsEllipseItem(outline) { } };

  • How to make a private property?

    I tried to make a private property in my *.m file: @interface MyClass (Private) @property (nonatomic, retain) NSMutableArray *stuff; @end @implementation MyClass @synthesize stuff; // not ok Compiler claims that there's no stuff property declared. But there's a stuff. Just in an anonymous category. Let me guess: Impossible. Other solutions?

  • Audio decoding delay when changing the audio language

    - by mahendiran.b
    My gstreamer Pipeline is like this Approach1 --------------input-selector->Queue->AduioParser->AudioSink | Souphttpsrc->tsdemux-->| | --------------- Queue->videoParser->videoSink In this approach 1, there is a delay in audio decoding when I toggle between various audio language. Approach2 ------ input-selector-> Queue->AduioParser->AudioSink | Souphttpsrc->tsdemux---multiqueue>| | ------- Queue->videoParser->VideoSink But there is no delay is observed in approach2. Can anyone please explain the reason behind this ? what is the specialty of multiqueue here?

  • What does =*> mean with regards to context free grammars?

    - by incrediman
    I've been reading a couple books/online references about compiler theory, and keep seeing that particular operator coming up every once in a while (as seen here), specifically when the current topic is context free grammars. What does it mean? As well, how does it differ from =>? Explanations with examples distinguishing => from =*> would be most helpful.

  • Why isn't the boost::shared_ptr -> operator inlined?

    - by Alan
    Since boost::shared_ptr could be called very frequently and simply returns a pointer, isn't the -> operator a good candidate for being inlined? T * operator-> () const // never throws { BOOST_ASSERT(px != 0); return px; } Would a good compiler automatically inline this anyway? Should I lose any sleep over this? :-)

  • Debug vs Trace in C#

    - by koumides
    All, As I understand statements like Debug.WriteLine() will not stay in the code in the Release build. On the other hand Trace.WriteLine() will stay in the code in the Release build. What is controling this behaviour? Does the C# compiler ignores everything from the System.Diagnostics.Debug class when the DEBUG is defined? I am just trying to understand the internals of C# and just curious. Thanks, MK

    - by subhashis
    The signature of the hashCode() method is public int hashCode(){ return x; } in this case x must be an int(primitive) but plz can anyone explain it to me that the number which the hashCode() returns must be a prime number, even number...etc or there is no specification ? the reason behind i am asking this question is i have seen it in different ids the auto generated code always returns a prime number, so i need to know why? thanks in advance

  • UnicodeDecodeError when redirecting to file

    - by zedoo
    Hi, I run this snippet twice, in the ubuntu terminal, (encoding set to utf-8) once with ./test.py and then with ./test.py >out.txt: uni = u"\u001A\u0BC3\u1451\U0001D10C" print uni Without redirection it prints garbage. With redirection I get a UnicodeDecodeError. Can someone explain why I get the error only in the second case, or even better give a detailed explanation of what's going on behind the curtain in both cases?
