  • Setting Frame.Content doesn't always work

    - by dan gibson
    I have a Frame control and I'm setting the Content property. If I set it twice, first to one control then to another, it shows the first control instead of the second. If I display a message box after setting it the first time then it works fine (ie it displays the second control). It's like I can only set Content once until the screen has been repainted. Calling Frame.UpdateLayout also doesn't help. What should I call after setting Content so that I can be sure that Content is actually set to what I specify?

  • Can I get away with this or is it just too crude and unpractical ?

    - by The_AlienCoder
    I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

  • Making Extension method Generic

    - by Ian
    In this post there's a very interesting way of updating UI threads using a static extension method. public static void InvokeIfRequired(this Control c, Action<Control> action) { if(c.InvokeRequired) { c.Invoke(() => action(c)); } else { action(c); } } What I want to do, is to make a generic version, so I'm not constrained by a control. This would allow me to do the following for example (because I'm no longer constrained to just being a Control) this.progressBar1.InvokeIfRequired(pb => pb.Value = e.Progress); I've tried the following: public static void InvokeIfRequired<T>(this T c, Action<T> action) where T : Control { if (c.InvokeRequired) { c.Invoke(() => action(c)); } else { action(c); } } But I get the following error that I'm not sure how to fix. Anyone any suggestions? Error 5 Cannot convert lambda expression to type 'System.Delegate' because it is not a delegate type

  • Tag <code>: how to "correct" publish it ?

    - by stighy
    Hi, i'm not sure to explain what i'm looking for. What's the name of the "source code parser" for publish code, in HTML ? For example, when i write some source code here in stack overflow, system auto-detect the sintax and write "correct" source code in html. I've noticed that exists the HTML <"code" tag, but it simply write source code in "courier" font. So i'm asking you if exists some "external" component that, given a text, parse it out correctly in a HTML page. Thank you!

  • Why I should use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

    - by The_AlienCoder
    When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

  • C# form - checkboxes do not respond to plus/minus keys - easy workaround?

    - by Scott
    On forms created with pre dotNET VB and C++ (MFC), a checkbox control responded to the plus/minus key without custom programming. When focus was on the checbox control, pressing PLUS would check the box, no matter what the previous state (checked/unchecked), while pressing MINUS would uncheck it, no matter the previous state. C# winform checkboxes do not seem to exhibit this behavior. Said behavior was very, very handy for automation, whereby the automating program would set focus to a checkbox control and issue a PLUS or MINUS to check or uncheck it. Without this capability, that cannot be done, as the automation program (at least the one I am using) is unable to query the current state of the checkbox (so it can decide whether to issue a SPACE key to toggle the state to the desired one). I've gone over the properties of a checkbox in the Visual Studio 2008 IDE and could not find anything that would restore/enable response to PLUS/MINUS. Since I am in control of the sourcecode for the WinForms in question, I could replace all checkbox controls with a custom checkbox control, but blech, I'd like to avoid that - heck, I don't think I could even consider that given the amount of refactoring that would need to be done. So the bottom line is: does anyone know of a way to get this behavior back more easily than a coding change?

  • Cost vs. Fun - Dilemma about learning a serverside language [closed]

    - by Ixx
    I want to learn a new server-side language. I already know Java. I'm fascinated by Scala, have read about it a lot, and want to get practical experience. But I also have some concerns of practical nature - I want to do the backend for many small, non-profit apps, and pay the lowest price for hosting possible. I also want that other people can easily contribute to these apps, if applicable. This leads me in PHP's direction. But I don't like PHP and would like to use these small projects to learn Scala instead. You see the problem, I don't want to pay more money each month, from my own pocket, for hosting. But I want to use these projects to learn Scala. Is there a practical solution for this?

  • Web host that handles excess php mailing [closed]

    - by CyberJunkie
    Possible Duplicate: How to find web hosting that meets my requirements? I'm having trouble choosing a host that meets my application's needs. Please kindly inform me what I should look for when choosing a web host. My application is similar to a reminder service that reminds users of events that they scheduled. I'm sending emails to users through a PHP script. I'm not sending one email to multiple recipients. Each recipient receives a different message. I plan to use cron jobs every minute and expect the application to send roughly 200 individual emails in 1 hour (for a small user base that may grow). I don't have hosting experience with this type of application. I plan to start on a shared host and move up in the future to vps or dedicated. Most shared hosts that I looked into allow 50-100 emails per hour with delays between mailings. What do you recommend?

  • How to create a shape acting like a textbox?

    - by subho100
    Please refer this control http://www.charlespetzold.com/blog/2009/10/Using-Text-Outlines-in-Silverlight.html The formattedtext control is a shape which helps to generate the shape of the text with proper geometry. I would like to make this control act like a text box with cursors and features like typing in from keyboard. Right now I use an invisible text box with a formattedtext control to act like that. But the cursor position always creates a problem when the size of the text is not equal to the size of the rendered text as shape. Can anyone please show the way to achieve this.

  • mvn clean install using java 1.5 or 1.6

    - by bruce
    When I do mvn clean install, I get this error: annotations are not supported in -source 1.3 (try -source 1.5 to enable annotations) But where do I put this -source 1.5 command? I tried all permutations with mvn clean install and couldn't get it to work. So I tried putting compilation in my pom, like this: <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> But that didn't work either.. What am I missing? Thanks!

  • Duplicate array but maintain pointer links

    - by St. John Johnson
    Suppose I have an array of nodes (objects). I need to create a duplicate of this array that I can modify without affecting the source array. But changing the nodes will affect the source nodes. Basically maintaining pointers to the objects instead of duplicating their values. // node(x, y) $array[0] = new node(15, 10); $array[1] = new node(30, -10); $array[2] = new node(-2, 49); // Some sort of copy system $array2 = $array; // Just to show modification to the array doesn't affect the source array array_pop($array2); if (count($array) == count($array2)) echo "Fail"; // Changing the node value should affect the source array $array2[0]->x = 30; if ($array2[0]->x == $array[0]->x) echo "Goal"; What would be the best way to do this?

  • New domain and submission to search engines

    - by Guandalino
    I have registered a new domain with a hosting company. They offer the feature that for each new domain there is an associated placeholder page. Actually it is a "Site not configured page" with some technical text and links to the hosting site. I could: submit its URL to search engines right now remove the page and submit the URL when the site will be online (could be a couple of months) replace the default page with "coming soon" contents and submit the URL opt for simplicity and add a blank html page having a focused and well descriptive title and maybe some meta tag other? I prefer 4 over 3 because at the moment there aren't precise project details to provide. What's the proper way to notify search engines that soon this site will be online, without getting penalized for side effects I'm not considering or aware of?
