  • C# Thread issues

    - by Mike
    What I have going on is a listview being dynamically created from a previous button click. Then ti starts a background worker in which should clear out the listview and populate the iistview with new information every 30 seconds. I continously get: Cross-thread operation not valid: Control 'listView2' accessed from a thread other than the thread it was created on. private void watcherprocess1Updatelist() { listView2.Items.Clear(); string betaFilePath1 = @"C:\Alpha\watch1\watch1config.txt"; using (FileStream fs = new FileStream(betaFilePath1, FileMode.Open)) using (StreamReader rdr = new StreamReader((fs))) { while (!rdr.EndOfStream) { string[] betaFileLine = rdr.ReadLine().Split(','); using (WebClient webClient = new WebClient()) { string urlstatelevel = betaFileLine[0]; string html = webClient.DownloadString(urlstatelevel); File.AppendAllText(@"C:\Alpha\watch1\specificconfig.txt", html); } } }

  • What Windows message is fired for mouse-up with modifier keys?

    - by Greg
    My WndProc isn't seeing mouse-up notifications when I click with a modifier key (shift or control) pressed. I see them without the modifier key, and I see mouse-down notifications with the modifier keys. I'm using the Windows Forms NativeWindow wrapper to get Windows messages from the WndProc() method. I've tried tracking the notifications I do get, and I the only clue I see is WM_CAPTURECHANGED. I've tried calling SetCapture when I receive the WM_LBUTTONDOWN message, but it doesn't help. Without modifier (skipping paint, timer and NCHITTEST messages): WM_LBUTTONDOWN WM_SETCURSOR WM_MOUSEMOVE WM_SETCURSOR WM_LBUTTONUP With modifier (skipping paint, timer and NCHITTEST messages): WM_KEYDOWN WM_PARENTNOTIFY WM_MOUSEACTIVATE WM_MOUSEACTIVATE WM_SETCURSOR WM_LBUTTONDOWN WM_SETCURSOR (repeats) WM_KEYDOWN (repeats) WM_KEYUP If I hold the mouse button down for a long time, I can usually get a WM_LBUTTONUP notification, but it should be possible to make it more responsive.. What am I missing? Thanks.

  • Station ID - more than IP

    - by bensiu
    Hello I am working on internal PHP application where users login only from our network (we are on dedicated IP and application is checking $_SERVER['REMOTE_ADDR'] and if is match our IP go thru if not - Bye However how I can identify from which station user is login ? Using cookie not gonna work - those are windows station working under control MS StedyState and all cookies are deleted every login I don't need nothing fancy like full MAC address just any unique ID (can not be application username - because users use different stations) Any ideas ? Maybe Javascript is able to grab some Unique detail from station's browser (IE 8) and pass this as hidden input? bensiu

  • New wxpython controls not displaying until resize

    - by acrosman
    I have created a custom control (based on a panel) in wxPython that provides a list of custom controls on panel within it. The user needs to be able to add rows at will and have those rows displayed. I'm having trouble getting the new controls to actually appear after they are added. I know they are present, because they appear after a resize of the frame, or if I add them before Show() is called on the frame. I've convinced myself it's something basic, but I can't find the mistake. The add function looks like this: def addRow(self, id, reference, page, title, note): newRow = NoteListRow(self.listPanel, id, reference, page, title, note) self.listSizer.Add(newRow, flag=wx.EXPAND | wx.LEFT) self.rows.append(newRow) if len(self.rows) == 1: self.highliteRow(newRow) self.Refresh() self.Update() return newRow I assume I'm missing something about how refresh and update are supposed to behave, so even a good extended reference on those would likely be helpful.

  • Hide TabControl buttons to manage stacked Panel controls

    - by Luca
    I need to handle multiple panels, containing variuous data masks. Each panel shall be visible using a TreeView control. At this time, I handle the panels visibility manually, by making the selected one visible and bring it on top. Actually this is not much confortable, especially in the UI designer, since when I add a brand new panel I have to resize every panel and then design it... A good solution would be using a TabControl, and each panel is contained in a TabPage. But I cannot find any way to hide the TabControl buttons, since I already have a TreeView for selecting items. Another solution would be an ipotethic "StackPanelControl", where the Panels are arranged using a stack, but I couldn't find it anywhere. What's the best solution to handle this kind of UI?

  • BindableAttribute, Combobox, Selectedvalue property - WinForms

    - by user63891
    I am deriving from combobox (WinForms) and am providing a new implementation for the Selectedvalue property. It works fine as is, but any change to the selectedvalue property is not updating other controls bound to the same "binding context" to change their values accordingly. I did try adding the BindableAttribute(true) to the property, but still it does nottrigger the change in value to the other linked controls. The control's DataBindings.add(...) is all set up. And other controls are also bound to the same data filed on the same datasource. Any ideas what i am doing wrong.

  • any way to get sharepoint groups with a given site url

    - by standley-nguyen
    Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

  • Large tables of static data with DBGhost

    - by Paulo Manuel Santos
    We are thinking of restructuring our database development and deployment processes by using DBGhost, we want to move away from the central development database and bring the database to the source control. One of the problems we have is a big table with static data (containing translated language strings), it has close to 200K rows. I know that our best solution is to move these stings into resource files, but until we implement that, will DbGhost be able to maintain all this static data and generate our development and deployment databases in a short time? And if not is there a good alternative to filling up this table whenever we need to?

  • Gridview with row being edited causing error when form submitted

    - by Chris Phelps
    Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

  • NSSavePanel selecting part of file name

    - by regulus6633
    How do I set the part of the file name that is selected in NSSavePanel? I only want the file name selected and not the file extension. Here's what I noticed. If I setAllowedFileTypes: for the save panel then only the file name is selected but not the file extension. However if I don't set the allowed file types then the file extension is selected along with the file name. I don't want to use setAllowedFileTypes but I still want to control the selection so that the file extension is not selected. Can that be done?

  • How do I retrieve and display html/asp/aspx page on different host using jQuery ajax?

    - by user717236
    I have an html page, which is a dynamically created asp/aspx page on http://host2.mydomain.com. I have no control over the html page. I cannot modify it in any such way. I cannot modify this page; so, setting document.domain is out of the question, unfortunately. I want to retrieve and display this page on http://host1.mydomain.com/page1.jsp using Ajax. FYI: host1 is being served by IIS 7 and Apache Tomcat (for JSP pages). And host2 is using IIS 7 and ASP. How can I retrieve this page using a Ajax POST request? Thank you.

  • Controlling CodeModel's code output formatting: putting lines between namespace declarations

    - by devoured elysium
    I'm making some experiments with Visual Studio's CodeModel. I tried creating a file with two namespaces in there through VS's Code Model: CodeModel codeModel = projItem.ContainingProject.CodeModel; codeModel.AddNamespace("Namespaces.FirstNamespace", "namespacestest.cs"); codeModel.AddNamespace("Namespaces.SecondNamespace", "namespacestest.cs"); the output of such code is: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Which is almost what I'm looking for. The only catch here is that I'd like to control the spacing: having at least one line between the first and the second namespace. Does by chance anyone know of a way of achieving this? This is what I want: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Thanks

  • How would you build a "pixel perfect" GUI on Linux?

    - by splicer
    I'd like build a GUI where every single pixel is under my control (i.e. not using the standard widgets that something like GTK+ provides). Renoise is a good example of what I'm looking to produce. Is getting down to the Xlib or XCB level the best way to go, or is it possible to achieve this with higher level frameworks like GTK+ (maybe even PyGTK)? Should I be looking at Cairo for the drawing? I'd like to work in Python or Ruby if possible, but C is fine too. Thanks!

  • bytea type & nulls, Postgres

    - by Thanatos
    I'm using a bytea type in PostgreSQL, which, to my understanding, contains just a series of bytes. However, I can't get it to play well with nulls. For example: =# select length(E'aa\x00aa'::bytea); length -------- 2 (1 row) I was expecting 5. Also: =# select md5(E'aa\x00aa'::bytea); md5 ---------------------------------- 4124bc0a9335c27f086f24ba207a4912 (1 row) That's the MD5 of "aa", not "aa\x00aa". Clearly, I'm Doing It Wrong, but I don't know what I'm doing wrong. I'm also on an older version of Postgres (8.1.11) for reasons outside of my control. (I'll see if this behaves the same on the latest Postgres as soon as I get home...)

  • Force redraw before long running operations

    - by Joshua
    When you have a button, and do something like: Private Function Button_OnClick Button.Enabled = False [LONG OPERATION] End Function Then the button will not be grayed, because the long operation prevents the UI thread from repainting the control. I know the right design is to start a background thread / dispatcher, but sometimes that's too much hassle for a simple operation. So how do I force the button to redraw in disabled state? I tried .UpdateLayout() on the Button, but it didn't have any effects. I also tried System.Windows.Forms.DoEvents() which normally works when using WinForms, but it also had no effect.

  • IO redirect engine with metadata

    - by hawk.hsieh
    Is there any C library or tool to redirect IO and be able to configured by a metadata. And provide a dynamic link library to perform custom process for feeding data into next IO. For example, network video recorder: record video: socket do_something() file preview video: socket do_something() PCI device http service: download file: socket do_something(http) file socket post file: socket do_something(http) file serial control: monitor device: uart do_something(custom protocol) popen("zip") socket I know the unix-like OS has IO redirect feature and integrate all application you want. Even socket IO you can use /dev/tcp or implement a process to redirect to stdout. But this is process based , the process's foot print is big , IPC is heavy. Therefore, I am looking for something to redirect IO in a process and the data redirect between IO is configurable with a metadata (XML,jason or others).

  • Re-measuring custom item renderer on a List

    - by leolobato
    I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

  • Why does Windows 7 change encoding of characters in runtime?

    - by LukLed
    I have a delphi form: and my code: when I run this form in Windows 7, I see: In design time, form had polish letters in first label, but it doesn't have them in runtime. It looks ok on Vista or Windows XP. When I set caption of second label in code, everything works fine and characters are properly encoded. First 5 codes of top label on Windows 7: 65 97 69 101 83 First 5 codes of top label on Windows Vista/XP: 165 185 202 234 140 First 5 codes of bottom label on every system: 165 185 202 234 140 Windows 7 changes encoding, why? My system settings seem to be ok. I have proper language set for non-unicode applications in control panel.

  • ASP.NET Controls Not Recognized

    - by Liam
    I just installed the release version of Visual Studio 2010, and it looks like there's something wrong with the standard ASP.NET server controls. When I create a basic server control, such as a TextBox, the editor underlines it in green and says (I also get no intellisense for ASP.NET controls): Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site, or the Web.config file is missing. The web site builds fine, and the Web.config file is not missing: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0" /> </system.web> </configuration> The controls work just fine in the code-behind, and they function correctly when I run the site. Is there some configuration problem here?
