  • How do I save a copy of the clipboard and then revert back to it?

    - by cksubs
    I'm reading words in a text box by simulating the key presses required to highligh and copy the text. When I'm done, I want the clipboard to be exactly how I found it. I was hoping I'd be able to do something like this: IDataObject clipboardBackup = Clipboard.GetDataObject(); Clipboard.Clear(); //Save other things into the clipboard here, etc// Clipboard.SetDataObject(clipboardBackup); But that doesn't seem to work. It looks like you can go the route of specifically trying for text, audio, pictures, etc. and then saving them accordingly. (I guess 'data object' is specialized like that in my example too, I was hoping it was generic.) I'd prefer not to use cases for every possible type of clipboard data, both to be more concise and to make sure I never lose the data regardless of format. Any tips for grabbing any and all of the clipboard and then restoring it?

  • ASP.NET SqlDataReader throwing error: Invalid attempt to call Read when reader is closed.

    - by Bugget
    This one has me stumped. Here are the relative bits of code: public AgencyDetails(Guid AgencyId) { try { evgStoredProcedure Procedure = new evgStoredProcedure(); Hashtable commandParameters = new Hashtable(); commandParameters.Add("@AgencyId", AgencyId); SqlDataReader AppReader = Procedure.ExecuteReaderProcedure("evg_getAgencyDetails", commandParameters); commandParameters.Clear(); //The following line is where the error is thrown. Errormessage: Invalid attempt to call Read when reader is closed. while (AppReader.Read()) { AgencyName = AppReader.GetOrdinal("AgencyName").ToString(); AgencyAddress = AppReader.GetOrdinal("AgencyAddress").ToString(); AgencyCity = AppReader.GetOrdinal("AgencyCity").ToString(); AgencyState = AppReader.GetOrdinal("AgencyState").ToString(); AgencyZip = AppReader.GetOrdinal("AgencyZip").ToString(); AgencyPhone = AppReader.GetOrdinal("AgencyPhone").ToString(); AgencyFax = AppReader.GetOrdinal("AgencyFax").ToString(); } AppReader.Close(); AppReader.Dispose(); } catch (Exception ex) { throw new Exception("AgencyDetails Constructor: " + ex.Message.ToString()); } } And the implementation of ExecuteReaderProcedure: public SqlDataReader ExecuteReaderProcedure(string ProcedureName, Hashtable Parameters) { SqlDataReader returnReader; using (SqlConnection conn = new SqlConnection(connectionString)) { try { SqlCommand cmd = new SqlCommand(ProcedureName, conn); SqlParameter param = new SqlParameter(); cmd.CommandType = System.Data.CommandType.StoredProcedure; foreach (DictionaryEntry keyValue in Parameters) { cmd.Parameters.AddWithValue(keyValue.Key.ToString(), keyValue.Value); } conn.Open(); returnReader = cmd.ExecuteReader(CommandBehavior.CloseConnection); } catch (SqlException e) { throw new Exception(e.Message.ToString()); } } return returnReader; } The connection string is working as other stored procedures in the same class run fine. The only problem seems to be when returning SqlDataReaders from this method! They throw the error message in the title. Any ideas are greatly appreciated! Thanks in advance!

  • How to set the size of a wx.aui.AuiManager Pane that is centered?

    - by aF
    Hello, I have three panes with the InfoPane center option. I want to know how to set their size. Using this code: import wx import wx.aui class MyFrame(wx.Frame): def __init__(self, parent, id=-1, title='wx.aui Test', pos=wx.DefaultPosition, size=(800, 600), style=wx.DEFAULT_FRAME_STYLE): wx.Frame.__init__(self, parent, id, title, pos, size, style) self._mgr = wx.aui.AuiManager(self) # create several text controls text1 = wx.TextCtrl(self, -1, 'Pane 1 - sample text', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) text2 = wx.TextCtrl(self, -1, 'Pane 2 - sample text', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) text3 = wx.TextCtrl(self, -1, 'Main content window', wx.DefaultPosition, wx.Size(200,150), wx.NO_BORDER | wx.TE_MULTILINE) # add the panes to the manager self._mgr.AddPane(text1, wx.CENTER) self._mgr.AddPane(text2, wx.CENTER) self._mgr.AddPane(text3, wx.CENTER) # tell the manager to 'commit' all the changes just made self._mgr.Update() self.Bind(wx.EVT_CLOSE, self.OnClose) def OnClose(self, event): # deinitialize the frame manager self._mgr.UnInit() # delete the frame self.Destroy() app = wx.App() frame = MyFrame(None) frame.Show() app.MainLoop() I want to know what is called when we change the size of the panes. If you tell me that, I can do the rest by myself :)

  • manage a hosted file by email

    - by Toc
    I need a service which allows me to edit a hosted text file by email. For example: I write an email to [email protected] with subject "ADD LINE 10" and sending it the mail body is inserted into myfile which is hosted on a server of someservice.ext. Same for "DELETE LINE 12" or "SUBSTITUTE LINE 15". If I write "ECHO FILE" or something similar, the service should send me an email with the updated content of the text file. Does it exist?

    I have a webpage that displays a calendar, and I want to change the background-color of any td that has their day number linked, so when I hover over that day, it changes the background-color. I thought this would work: .main-calendar td { width:14%; height:100px; text-align:center; border:1px solid #000; font-size:20px; vertical-align:middle; display:block; } table.main-calendar td a:hover, table.main-calendar td a:visited { display:block; text-decoration:none; background-color:red; color:#fff; } table.main-calendar td a:link { display:block; text-decoration:none; background-color:green; color:#fff; } Any help is appreciated.

  • Format number as I type Expand this post

    - by conorhiggins
    Hi I am working on an app at the moment that requires number input to be formatted as the textfield changes as well as perform a calculation. I have the text fields set up so that as the user types notifications are passed out and a calculation is performed. However what I need to do now is format the text to be in this style: €1,000,000 rather than 1000000. I have this working for the output of the calculation already but everytime I try to apply it to the input text the simulator seems to crash or at least freezes for a while. I'd imagine its a simple enough fix.

  • Palm webOS CSS Targeting Hack?

    - by Tom
    Although it is not good practice, I am looking for a CSS hack to target Palm webOS. The problem is that Safari 3+ is awesome, and I can do some things like gradient background animations on text, but only in Safari. Right now I use @media screen and (-webkit-min-device-pixel-ratio:0) {} and it works like a charm, no Opera, Firefox, or whatever, because if I set the background to the image as I do in Safari they will all be ruined. But Palm's browser is based on webkit, and it uses the rules inside, and Palm's browser doesn't support text backgrounds so all I get is the image moving, no text. I would prefer a CSS hack, but if need be a Javascript one will do.

  • CloseHandler<Window> and Window.ClosingHandler() working differently in IE

    - by stuff22
    It seems that CloseHandler and Window.ClosingHandler() are not working or are not triggering the events in the same way under IE as opposed to Firefox. Window.addWindowClosingHandler(new Window.ClosingHandler() { @Override public void onWindowClosing(ClosingEvent event) { event.setMessage(message); } Window.addCloseHandler(new CloseHandler<Window>() { @Override public void onClose(CloseEvent<Window> event) { //Window.alert("debug1"); if(recordId!=null){ DatabaseQueryServiceAsync dbQueryService = DatabaseQueryService.Util.getInstance(); dbQueryService.releaseRecordLock(recordId, new AsyncCallback<String>() { @Override public void onFailure(Throwable arg0) { } @Override public void onSuccess(String arg0) { } }); } } }); }); For example, the ClosingHandler under IE displays the message when I swap a panel within within my widget. This does not occur in Firefox. The CloseHandler doesn't seem to trigger at all when the window closes in IE, but does so in firefox. The interesting thing to point out there, is that when I put a Window.alert("debug1") message in the addCloseHandler() method it DOES run the callback below, but as soon as I remove it, the callback doesn't happen. In firefox it works and runs the callback in both situations. So, I'm basically pulling my hair out not really understanding what's going on. Any help would be greatly appreciated. Thanks.

  • FQL query using stream table doesn't accept app access token

    - by tougher
    I've searched stackoverflow all day long to find an answer without luck, so here we go. I'm trying to fetch data from the stream table like this: FQL: SELECT post_id, message, created_time FROM stream WHERE source_id = 131559313586863 URL: http:// graph.facebook.com/fql?q=SELECT+post_id%2C+message%2C+created_time+FROM+stream+WHERE+source_id+%3D+131559313586863&access_token=10669xxxxx74470|PF-7GSdBx0Nxxxxxkdi1KwSQG-w But I get a 400 Bad Request as response with the error message: "An access token is required to request this resource.". I'm fetching an application access token with this url: https:// graph.facebook.com/oauth/access_token?client_id=FACEBOOK_APP_ID&client_secret=FACEBOOK_APP_SECRET&grant_type=client_credentials Facebook state in this blog post that "You will need to pass a valid app or user access token to access this functionality.". Functionality refers to /feed and /posts (the stream table). Futhermore this wiki tells the same story about using the stream table, "From June 3 2011 a token is required to query this table. You can use any application or user token to make the query.". Does anyone see my hopefully obvious flaw? Please note: The profile in the FQL query is public. I need this to run userless though a cronjob. No user interaction is possible. The request works if I replace the app access token with my own user token from https:// developers.facebook.com/tools/explorer Sorry for breaking the URL's. I need more reputation to post more than 2 links :-/

  • Setting background color in gvim

    - by petersohn
    I use a terminal with white text on black background (I just like it better), so I wrote the following line in my .vimrc file: set background=dark However, gvim has black on white text. How do I do either of the following: Set the background of gvim to black Check in .vimrc if I'm using gvim I tried this: I started up gvim, and typed echo &term. The answer was "builtin_gui". So I wrote the following into .vimrc: if &term == "builtin_gui" set background=light else set background=dark endif Somehow, it didn't work.

  • Why am I getting two section headers on this grouped table?

    - by Andy
    I'm sure this is some easy-to-fix issue that I've missed, but I can't figure it out. I've got a grouped table view with 3 sections. I'm using the following code to generate section headers: -(NSString*)tableView:(UITableView*)tableView titleForHeaderInSection:(NSInteger)section { if (section == 0) { NSString *header = @"Header 1"; return header; } if (section == 1) { NSString *header = @"Header 2"; return header; } else { NSString *header = @"Header 3"; return header; } } When my table is displayed, there are two headers for each section - one with white text on a gray bar that stretches across the screen (like the letter separators in the Contacts app), and one in gray text on the table background (which is the one I want). Both headers have identical text. Where is the first header coming from?

  • Image appearing in the wrong place.

    - by Luke
    I have a list that I want to precede on each line with a small image. The CSS: .left div.arrow{background-image: url(../images/design/box.png); float:left; height:15px; width:15px; margin-right:2px;} .left a.list:link, a:visited, a:active {color:black; font-size:0.8em; text-decoration:none; display:block; float:left;} The HTML: <div class="panel">My quick links</div> <div class="arrow"></div> <a href="/messages.php?p=new" class="list">Send a new message</a> <br /> <div class="arrow"></div> <a href="/settings.php#password" class="list">Change my password</a> <br /> <div class="arrow"></div> <a href="/settings.php#picture" class="list">Upload a new site image</a> <br /> As you can see, each image should go before the writing. On the first line, the text "Send a new message" has the preceeding image. However, each line afterwards has the image at the end. So "Send a new message" has an image at the start and finish. It is like the images are staying at the end of the previous line. Any ideas?

  • gen_server with a dict vs mnesia table vs ets

    - by pablo
    Hi, I'm building an erlang server. Users sends http requests to the server to update their status. The http request process on the server saves the user status message in memory. Every minute the server sends all messages to a remote server and clear the memory. If a user update his status several times in a minute, the last message overrides the previous one. It is important that between reading all the messages and clearing them no other process will be able to write a status message. What is the best way to implement it? gen_server with a dict. The key will be the userid. dict:store/3 will update or create the status. The gen_server solves the 'transaction' issue. mnesia table with ram_copies. Handle transactions and I don't need to implement a gen_server. Is there too much overhead with this solution? ETS table which is more light weight and have a gen_server. Is it possible to do the transaction in ETS? To lock the table between reading all the messages and clearing them? Thanks

  • Chrome Extension contenteditable get and set caret position

    - by jwize
    I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

  • How to detect when UITextField become empty

    - by Jakub
    Hello, I would like to perform a certain action when UITextField becomes empty (user deletes everything one sign after another or uses the clear option). I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

  • In Delphi, Is there a way to adjust the line spacing of a TMemo?

    - by Kieran
    I'm working with a TMemo component to display some text in a limited space. Currently it's using a truetype font which doesn't ship with windows and is installed by the app when it runs. On my PC (Running Windows XP), the spacing between each line of text seems to be about eight pixels. On a different PC running Windows 7, the line spacing seems to be about 14 pixels, which is pushing the bottom row of text out of visibility on the memo. So, My question is really this: Is this caused by the different versions of Windows? It's all I could think that was different. Is there some way I can adjust this value so it would be consistent across all instances of the application, wherever it was running? Alternatatively, is there a different component I could use which might let me tweak this value?

  • SQL Access INSERT INTO Autonumber Field

    - by KrazyKash
    I'm trying to make a visual basic application which is connected to a Microsoft Access Database using OLEDB. Inside my database I have a user table with the following layout ID - Autonumber Username - Text Password - Text Email - Text To insert data into the table I use the following query INSERT INTO Users (Username, Password, Email) VALUES ('004606', 'Password', '[email protected]') However I seem to get an error with this statement and according to VB it's a syntax error. But then I tried to use the following query INSERT INTO Users (Username) Values ('004606') This query seemed to work absolutely fine... So the problem is I can insert into just one field but not all 3 (excluding the ID field because it's an autonumber). Any help would be appreciated, Thanks

  • Binding multiple arrays for WHERE IN in PostgreSQL

    - by Alec
    So I want to prepare a query something like: SELECT id FROM users WHERE (branch, cid) IN $1; But I then need to bind a variable length list of arrays like (('a','b'),('c','d')) to it. How do I go about doing this? I've tried using ANY but can't seem to get the syntax right. Cheers, Alec Edit: After some fiddling around, this is valid syntactically: SELECT id FROM users WHERE (branch, cid) = ANY ($1::text[][]); and then binding the string '{{a,b},{c,d}}' to $1 but throws the error "operator does not exist: record = text". Changing 'text' to 'record' then throws "input of anonymous composite types is not implemented". Any ideas?
