  • ASP.NET validation controls

    - by mehmet6parmak
    Hi All, I want to use Validation Controls but I dont want them to show their Error Messages when invalid data exist. Instead I'm going to iterate through the validation controls and show error messages inside my little ErrorMessage Control for (int i = 0; i < Page.Validators.Count; i++) { if (!Page.Validators[i].IsValid) { divAlert.InnerText = Page.Validators[i].ErrorMessage; return false; } } I'm doing this because i have little space to show the error message. You can ask why are you using validation control if you dont want to show them My asnwer is "I use them for validation logic they handle" I looked the properties of the validation controls and cant find something that wil help me doing this. Any Idea? Thanks

  • How to clean completly select2 control?

    - by Candil
    I'm working with the awesome select2 control. I'm trying to clean and disable the select2 with the content too so I do this: $("#select2id").empty(); $("#select2id").select2("disable"); Ok, it works, but if i had a value selected all the items are removed, the control is disabled, but the selected value is still displayed. I want to clear all content so the placeholder would be showed. Here is a example I did where you can see the issue: http://jsfiddle.net/BSEXM/ HTML: <select id="sel" data-placeholder="This is my placeholder"> <option></option> <option value="a">hello</option> <option value="b">all</option> <option value="c">stack</option> <option value="c">overflow</option> </select> <br> <button id="pres">Disable and clear</button> <button id="ena">Enable</button> Code: $(document).ready(function () { $("#sel").select2(); $("#pres").click(function () { $("#sel").empty(); $("#sel").select2("disable"); }); $("#ena").click(function () { $("#sel").select2("enable"); }); }); CSS: #sel { margin: 20px; } Do you have any idea or advice to this?

  • Retriving data from ListView control

    - by Josh
    I have a ListView control set up in details mode with 5 columns. It is populated by code using the following subroutine: For j = 0 To 14 cmd = New OleDbCommand("SELECT TeacherName, ClassSubject, BookingDate, BookingPeriod FROM " & SchemaTable.Rows(i)!TABLE_NAME.ToString() & " WHERE (((BookingDate)=" & Chr(34) & Date.Today.AddDays(j) & Chr(34) & ") AND ((UserName)=" & Chr(34) & user & Chr(34) & "));", cn) dr = cmd.ExecuteReader Dim itm As ListViewItem Dim itms(4) As String While dr.Read() itms(0) = dr(0) itms(1) = SchemaTable.Rows(i)!TABLE_NAME.ToString() itms(2) = dr(1) itms(3) = dr(2) itms(4) = dr(3) itm = New ListViewItem(itms) Manage.ManageList.Items.Add(itm) End While Next Note that this is not the full routine, just the bit that populated the grid. Now I need to retrieve data from the ListView control in order to delete a booking in my database. I used the following code to retrieve the content of each column: ManageList.SelectedItems(0).Text But it only seems to work on index 0. If I do: ManageList.SelectedItems(3).Text I get this error: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index I'm pretty much stumped, it seems logical to me that index 1 will point to the 2nd column, index 2 to the 3rd etc, as it's 0 based? Any help would be appreciated, thanks.

  • Group traffic shaping with traffic control?

    - by mmcbro
    I'm trying to limit the output bandwidth generated by an application with linux tc. This application sends me the source port of the request that I use has a filter to limit each user at a given downloadspeed. I feel that my setup could be managed way better if I had a better knowledge of linux tc. At the application level users are categorized as members of a group, each group have a limited bandwidth. Example : Members of group A : 512kbit/s Members of group B : 1Mbit/s Members of group C : 2Mbit/s When a user connects to the application, it retrieves the source port to the origin of the request from the user and sends me the source port and the bandwidth at which the user must be limited depending on group to which it belongs. With these informations I must add the appropriate rules so that the user (the source port in reality) is limited to the right bandwidth. If the user that connect isn't a member of any group it should be limited at a default bandwidth speed. I'm actually managing this by using a self made daemon that add or remove rules from when it receive a request from the application. With my little knowledge of tc I'm not able to limit other users (ones that aren't in a group, all others in fact) at a default speed and my configuration seems awful to me. Here is the base of my tc qdisc and classes : tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbps ceil 125mbps To classify a user at a given speed I have to add one subclass and then associate one filter to it : # a member of group A tc class add dev eth0 parent 1:1 classid 1:11 htb rate 512kbps ceil 512kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 50001 flowid 1:11 # a member of group A again tc class add dev eth0 parent 1:1 classid 1:12 htb rate 512kbps ceil 512kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 61524 flowid 1:12 # a member of group B again tc class add dev eth0 parent 1:1 classid 1:13 htb rate 1000kbps ceil 1000kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 57200 flowid 1:13 I already know that a source port could be the same if its coming from a different IP address the thing is the application is behind a proxy so I don't have to manage any IP address in that situation. I would like to know how to manage the fact that for all other users (request/source port, whatever you name it) could be limited at a given speed each. I mean that each connection should be able to use at max 100kbit/s for example, not a shared 100kbit/s. I also would like to know if there is a way to simplify my rules. I don't know if it is possible to use only one class per group and associate multiple filters to the same class so each users could be handled by one class and not one class per user. I appreciate any advice, thanks.

  • ASP.net MVC: Getting a Partial View's HTML from inside of the controller

    - by Harry
    I have developed a simple mechanism for my mvc website to pull in html via jquery which then populates a specified div. All is well and it looks cool. My problem is that i'm now creating html markup inside of my controller (Which is very easy to do in VB.net btw) I'd rather not mix up the sepparation of concerns. Is it possible to use a custom 'MVC View User Control' to suit this need? Can I create an instance of a control, pass in the model data and render to html? It would then be a simple matter of rendering and passing back to the calling browser.

  • Xcode + Perforce: it frequently shows me the spinning wheel for no reason! What can i do?

    - by GamingHorror
    While working on an Xcode project i keep getting the spinning wheel while switching files, scrolling, searching, typing, debugging, removing breakpoints, switching back from another app or saving. It also happens before compiling but usually it just happens from time to time for no apparent reason. This is the second time this started happening in a Xcode project and it's driving me nuts. It completely breaks my flow of work to have to wait for the spinning wheel to go away (2-5 seconds). What on earth could i possibly do to ... figure out what's causing the problem? resolve the problem? More details: When any project is small, everything is super-smooth with Xcode and Perforce. Two of my projects eventually had this spinning wheel problem after about 4 weeks of work. It only happened with those two projects so far. They consist of around 1000-1200 files in source control, most of them assets. The problem occurs even if i manually check out the whole project in Perforce. The problem is gone when i copy the project directory and work in the copy which is no longer under source control, or if i create a branch in Perforce and work in the branch (under source control). One of these projects i shared with a colleague, and he had exactly the same issues on his Mac. We eventually switched to Subversion and the spinning-wheel issue immediately went away. Now that i've received an updated copy of the project and simply put it under Perforce as a new project, the problem also went away (so far it did not resurface). It leads me to think that it may be caused by a larger number of file revisions. The server itself (version 2009.1) is on a different (Windows) machine on my LAN, so there's definetely no Internet lag involved. The complete repository is just 1 GB in size spread over a dozen projects or so. I'm sorry if the question seems more like a support inquiry for Perforce. However i'm using the free version of Perforce so i'm not entitled to get support from them. I hope no one minds me asking here. I'm really bummed out by this. I don't want to have to create a new branch for the project each time the spinning wheel problem surfaces.

  • Does javascript event handling occur inside or outside the program flow?

    - by Carlo Roosen
    This question is related to Javascript event handling and flow control, but it is one step beyond. The question that remains unanswered is: when an event is fired and control is returned to the browser, could the browser decide to handle other events first (fired by other scripts or user action) (A), or will it always handle my event directly (B)? The question is important, because in case (B) you can rely on the fact that nothing has been changed between firing the event and the event handler, while (A) gives no guarantees whatsoever. My first guess is (B), how else could stopPropagation() and preventDefault() work? But giving it a second thought, it is no hard evidence.

  • Binding for MinWidth property does not work in Silverlight

    - by Akash Kava
    I have noticed something very unusual today, I need to bind "MinWidth" property of TextBlock to some value, however following example does not work. It only accepts MinWidth at a time of creation, but after that it is not affected at all if LeftWidth property is changed at runtime, however if I bind LeftWidth property to WidthProperty it works well. Binding b = new Binding("LeftWidth"); // following never changes layout of control tb.SetBinding(TextBlock.MinWidthProperty,b); However, this one works correctly, // following never changes layout of control tb.SetBinding(TextBlock.WidthProperty,b); Now I also did hook events and tried to do InvalidateMeasure and InvalidateArrange on TextBlock, but it has no effect. Seems like Changing MinWidth Property after layout pass does not work at all. Can it be a bug in Silverlight? or Does anyone have any idea at all why MinWidth does not redo the layout?

  • Dynamically cast a control type in runtime

This works well, but my problem is the following: private Type activeControlType; private void addControl(ContainerControl inputControl, string ControlName, string Namespace, string ControlDisplayText, DataRow drow, string cntrlName) { Assembly assem; Type myType = Type.GetType(ControlName + ", " + Namespace); assem = Assembly.GetAssembly(myType); Type controlType = assem.GetType(ControlName); object obj = Activator.CreateInstance(controlType); Control tb = (Control)obj; tb.Click += new EventHandler(Cntrl_Click); inputControl.Controls.Add(tb); activeControlType = controlType; } private void Cntrl_Click(object sender, EventArgs e) { string test = ((activeControlType)sender).Text; //Problem ??? } How do I dynamically cast the sender object to a class that I can reference the property fields of it. I have googled, and found myself trying everything I have come across..... Now I am extremely confused... and in need of some help Thnx JT

  • Read the contents of a ComboBox (or any other windows control) [closed]

    - by Homer
    I have a program that reads the contacts from my phone, but I can't export them from it. I'd like to use another program to read the contents of the controls on the original program. In this case, I would like to export the content of a dropdown list (combobox), containing these contacts. Can someone recommend a good program for this or recommend another method? I know I saw something for this last year on lifehacker.com in a collection of diagnostic tools, but I can't find it now.

  • Custom Android control with children

    - by Gromix
    Hi, I'm trying to create a custom Android control that contains a LinearLayout. You can think of it as an extended LinearLayout with fancy borders, a background, an image on the left... I could do it all in XML (works great) but since I have dozens of occurences in my app it's getting hard to maintain. I thought it would be nicer to have something like this: /* Main.xml */ <MyFancyLayout> <TextView /> /* what goes inside my control's linear layout */ </MyfancyLayout> How would you approach this? I'd like to avoid re-writing the whole linear layout onMeasure / onLayout methods. This is what I have for the moment: /* MyFancyLayout.xml */ <TableLayout> <ImageView /> <LinearLayout id="container" /> /* where I want the real content to go */ </TableLayout> and /* MyFancyLayout.java */ public class MyFancyLayout extends LinearLayout { public MyFancyLayout(Context context) { super(context); View.inflate(context, R.layout.my_fancy_layout, this); } } How would you go about inserting the user-specified content (the TextView in main.xml) in the right place (id=container)? Cheers! Romain ----- edit ------- Still no luck on this, so I changed my design to use a simpler layout and decided to live with a bit of repeated XML. Still very interested in anyone knows how to do this though!

  • Control scheduled tasks execution

    - by SJuan76
    We are a small shop. I am mainly a programmer, but due to being the only one that risks to manage our servers, the task has fallen on me (yet I it is still a secondary function so I cannot give it too much time). Over the course of years we have needed to create a decent number of .bat scripts that run as scheduled tasks in our servers (dump DB servers, SVN servers, copy files, etc.). Manually checking that everyone has proceeded ok is a time consuming task. I could get them to send an email on completion, but then I would get swarmed by lots of emails each morning. If I setup them to only e-mail on failure, I might miss the instances where the error causes the task to abort (or even not to start). Are there other alternatives? We are currently using Windows 2003 R2, but we are thinking of adding some Linux server soon, so a cross-platform solution would be best.

  • server control properties

    - by Richard Friend
    Okay i have a custom server control that has some autocomplete settings, i have this as follows and it works fine. /// <summary> /// Auto complete settings /// </summary> [System.ComponentModel.DesignerSerializationVisibility (System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty), Category("Data"), Description("Auto complete settings"), NotifyParentProperty(true)] public AutoCompleteLookupSettings AutoComplete { private set; get; } I also have a ParameterCollection that is really related to the auto complete settings, currently this collection resides off the control itself like so : /// <summary> /// Parameters for any data lookups /// </summary> [System.ComponentModel.DesignerSerializationVisibility(System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty)] public ParameterCollection Parameters { get; set; } What i would like to do is move the parameter collection inside of the AutoCompleteSettings as it really relates to my autocomplete, i have tried this but to no avail.. I would like to move from <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" /> <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </cc1:TextField> To <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" > <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </AutoComplete> </cc1:TextField>

  • Will using a VCS help me as a web dev?

    - by jsims281
    I'm thinking of trying a VCS such as subversion, to manage my next project, but I'm not sure if will offer any real benefits for me as a web developer. As I understand it, one of the major benefits of a VCS is that a group of people can work on a project at once. Reading material on the subject seems pretty one sided: "Using a version control system is an absolute must for a developer of a project above a few hundred lines of code" ...and I've got a feeling it could become a chore, with not many benefits. I work on development server on the local network, so any amount of people can work on the files already. If anyone needs to get in remotely, they use FTP. What would a modern version control system give me on top of this?

  • How to control linux workstations- with poloices.

    - by redknight
    I am going to be administering a small network of linux based workstations for a charity institution (not all have the same distro- some are ubuntu and some are fedora). Is there something in Linux that is similar to group policy in windows?. For example I would like to standardize the wallpapers - have only firefox as a browser - default VLC as the media player etc etc. Thank you, any suggestions are very appreciated.

  • Remote access to server via service control panel for non-admin user in Windows 2008

    - by user2278
    I'm trying to configure my Windows 2008 servers so that my developers can view their status without needing to log on to the box or be an admin. Unfortunately, the permissions set in Windows 2008 for remote non-admin users don't include the ability to enumerate or otherwise query services. This causes anything that contacts the SCM on the far end to fail (Win32_Service, sc.exe, services.msc etc). How do I set up permissions so that they can at least list the services and see if they are running?

  • How do I refer to a windows form control by name (C# / VB)

    - by Alex
    Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do: For each ctrl as Control in TabPage.Controls If ctrl.Name = "UserName" Then ' Do something End If Next This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only... EDIT Thanks for the response so far. Here is a bit more detail. I have a windows form with three tabpages, all of which a very similar in design and function i.e. same drop down menus, labels, react in simlar way to events etc. Rather than write code for each event per tabpage I have built a class that controls the events etc. per tabpage. For example, on each tabpage there is a Label called "RecordCounter" that simply shows the number of rows in the datagridview when it is populated by selection of a variable in a drop down menu. So what I want to be able to do is, upon selection of a variable in the drop down menu, the datagridview populates itself with data, and then I simply want to display the number of rows in a label ("RecordCounter"). This is exactly the same process on each tabpage so what I am doing is passing the tabpage to the class and then I want to be able to refer to the "RecordCounter" and then update it. In my class I set the ActivePage property to be the TabPage that the user has selected and then want to be able to do something like: ActivePage.RecordCounter.Text = GetNumberOfRows()

    We have analog IR cameras (not IP Cameras) and they are connected to DVR model no is (DVR Model: DVR H264, 16 Channel - ECOR264-16X1). We assigned a static IP to DVR and able to view all the cameras connected to it. Our requirement is to view individual cameras and recording option in remote location (the recorded data should store in remote) as like IP Cameras. Is it possible, if not, are there any DVR Model which can support like this.

  • Disable Control-L hotkey on YouTube

    - by Heptite
    I am used to using Ctrll to access my address bar. Unfortunately YouTube "helpfully" defines Ctrll as a hotkey to jump forward several seconds in the currently playing video, so I need a way to stop YouTube from adding that key binding. A Greasemonkey/Scriptish userscript that disables the binding after page load would be acceptable. To be clear, this is while I am on a YouTube video's page, not on a third-party site that has embedded a YouTube video, and the behavior occurs when the Flash player does not have focus. Note: I am aware that Altd does the same as Ctrll in Firefox, but I'm too used to Ctrll and I'd rather not be forced to switch. Edit: OS-specific solutions are less desirable since I use multiple OSes; in-browser solutions are preferred.
