  • Redirect WinForms web browser Control pop ups to another WinForms web browser control with form data

    - by Scott Chantry
    I have a c# web browser and one of the pages it displays has a form. When the form is submitted it posts data to a new window in IE. I want to catch that data and forward it to another C# web browser that I have in my application. So I don't want it to open an IE browser when the javascript function window.open is called, I want it to open it in the 2nd browser window.

  • WPF ShowDialog returns immediately

    - by dthrasher
    Sometimes when I call ShowDialog on an OpenFileDialog Window in WPF, the dialog closes immediately with a return value of false. I'm calling ShowDialog in response to a button click event. I can reproduce this problem using the sample code for OpenFileDialog on MSDN: // Configure open file dialog box Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog(); dlg.FileName = "Document"; // Default file name dlg.DefaultExt = ".txt"; // Default file extension dlg.Filter = "Text documents (.txt)|*.txt"; // Filter files by extension // Show open file dialog box Nullable<bool> result = dlg.ShowDialog(); // Process open file dialog box results if (result == true) { // Open document string filename = dlg.FileName; } The problem occurs intermittently when I run my solution in Debug mode from Visual Studio 2008 SP1. It's quite annoying. Is this a known issue? Are there workarounds?

  • Is it possible to expose data from Oracle using OData?

    - by Michael Rosario
    From my personal research, it appears that OData implementations depend extensively on MS Entity framework. It would seem possible to implement the OData producer protocol using an open ORM like NHibernate in C# or Hibernate in Java. In the best of all worlds, it would be cool to expose data using OData protocol from Oracle. I am open to other open solutions like Java, JRuby, etc. Thanks in advance for your time.

  • Why does DEP kill IE when accessing Microsoft FTP?

    - by Sammy
    I start up IE (9.0.8112.16421) with about:blank and I go to ftp://ftp.microsoft.com/ I press Alt, click View and then Open FTP Site in Windows Explorer. At this point IE stops responding and eventually crashes (though the window is still active, sometimes) and I get the usual Windows dialog box saying that the program has stopped working. From this dialog box I click on the option to try to find solutions to the problem and the progress bar just keeps scrolling without giving me any result page whatsoever, so I have to abort by clicking Cancel. Then I get the bubble type of pop-up message from the system tray saying that DEP has stopped the program from executing. What gives? Why would DEP (part of Microsoft Windows) be preventing IE (a Microsoft product) from performing a perfectly legitimate action from Microsoft's own FTP site? The OS is Windows Vista HP SP2, Swedish locale. Screenshots as follows... Update: I normally have UAC disabled, but I have discovered that enabling it has an effect on IE when I click the FTP option from the View menu, just as I suspected. I basically tried starting IE in its 32-bit and 64-bit version, with and without add-ons, and switching UAC on and off, and then trying to go to View and the FTP option (as shown above). Here are the results. With UAC off and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message This is the information and warning message I get if I use IE 64-bit: The first message is an FTP proxy warning. It says that the folder ftp://ftp.microsoft.com/ will be write-protected because proxy server is not configured to allow full access. It goes on to say that if I want to move, paste, change name or delete files I must use another type of proxy, and that I should contact the system admin for more information (the usual recommendation when they have no clue of what's going on). What the heck is all this about? I don't even use a proxy server, as you can see from the next screenshot (Internet Options, Connections, LAN settings dialog). That second message only states that the FTP site cannot be viewed in (Windows) Explorer. With UAC off, I always get these two messages when running the 64-bit version of IE. With UAC on and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action As you can see from this list, if I have UAC enabled I actually get rid of these messages and opening the FTP site in Windows Explorer (from IE) actually works (except for 32-bit version which still crashes). Here is the security warning message: The fact that the 32-bit IE still crashes could be an indicator that this has something to do with one or several add-ons in that bit-version of IE. The 32-bit IE doesn't crash if it's started with the extoff flag. If this is affecting only the 32-bit IE then it's only normal that the 64-bit IE doesn't have this problem because it would not be using any of the add-ons used by the 32-bit version, they are not compatible with 64-bit (although some add-ons work both with 32-bit and 64-bit IE). Figuring out which add-on (if any) is causing this problem is a whole new question... but I seem to be closer to an answer now, and a possible solution. I could of course just add IE (32-bit) in the exclusion list of DEP. In fact, I have already tested this and it causes IE to perform this task without hiccups. But I don't really want to disable DEP, or force it on all Windows programs and services (except the ones I strictly specify in the exception list). (In other words DEP can't really be completely disabled, you can only switch between two modes of operation.) Update 2: This is interesting... I start 32-bit IE, go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. The result is a crash!! Then I start 32-bit IE with extoff flag to disable add-ons, I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. I get the security warning, as expected with UAC enabled, and it opens up in Windows Explorer. Now... I close Windows Explorer, and I close IE. I then start 32-bit IE (normal start, with add-ons), I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. Now this time it doesn't crash! Instead, I get the screenshot number 5 as seen above. This is the FTP proxy warning message. Now get this... if I click the close button to get rid of this message, what happens is that Firefox starts up, and it goes to ftp://ftp.microsoft.com/ The fact that this works with 32-bit IE (with add-ons) the second time around, is because I am still logged in as anonymous to the FTP server. The log-in has not timed out yet. Standard log-in timeout for FTP servers is usually 60 to 120 seconds. I got logged in to it the first time I ran 32-bit IE with the extoff flag (no add-ons) which actually works and connects using Windows Explorer. Update 3: The connection to the FTP server has timed out by now. So now if I run 32-bit IE (with add-ons) and repeat the steps as before it crashes, just as expected... In conclusion: If I have already been connected to the FTP server via Windows Explorer, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu to open it in Windows Explorer, it gives me a FTP proxy server warning and then opens the address in default web browser (Firefox in my case). If I have not been connected to the FTP server via Windows Explorer previously, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu top open it in Windows Explorer, then it crashes IE! This is just great... It's not that I care much for using Internet Explorer or the Windows Explorer to log in to FTP servers. This just shows why IE is not the best browser choice. This reminds me of the time when Microsoft was enforcing the use of Internet Explorer as default browser for opening web links and other web resources, despite the fact that the user had installed an alternative browser on the system. Even if the user explicitly set the default browser to be something else and not Internet Explorer in the Windows options, IE would still pop up sometimes, depending on what web resources the user was trying to access. Setting default browser had no effect. It was hard-coded that IE is the browser of choice, especially when accessing Microsoft product or help pages. The web page would actually say that you are not using IE, and that you must open it in IE to view it. Unfortunately you would not be able to open it manually in a different browser by simply copying and pasting the URL from the address bar, because it would show a different URL, and the original URL would re-direct to the "you are using the wrong browser" page so you would not have the time to cut it to clipboard. Thankfully those days are over. Now-days Microsoft is forced to distribute IE and WMP free versions of Windows for the EU market. The way it should be! These programs have to be optional, not mandatory.

  • Question about using ServiceModelEx's "WCFLogbook" from "Programming WCF Services" book

    - by Bill
    I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). Of course the example application utilizes Juval's ServiceModelEx library and logs faults/errors to a "WCFLogbook" database. Unfortunately, when the sample app faults, I get the following new error: "Cannot open database "WCFLogbook" requested by the login. The login failed. Login failed for user 'Bill-PC\Bill'." I suspect the error occurs as a result of not finding the "WCFLogbook" database, which I believe still needs to be created. Included in the library source directory, there are two files -WCFLogbookDataSet.xsd and WCFLogbook.sql; which neither seem to be referenced anywhere within the library code. This leads me to beleive that the sql and xsd files are there to be used to create the database somehow in SQL. Could someone please advise me if I am going in the correct direction here and if whether these files can be used to create the database (and if so, how)?

  • MS Access 2003: Can data disappear from records and how do I test for this and prevent it?

    - by user328960
    Problem and about the database: Data from a record in Access 2003 database has disappeared. This database has 1 backend and 3 frontends, multiple users and is hosted on Citrix. Within this database, we have records of all clients served, ranging in the 1000s. Background info: The form for client data entry is set up with various subforms, including both a "programs enrolled" subform and a "services" subform. A client can be enrolled in multiple programs. Once enrolled in a program, services can be entered for that program area using the services subform. There are multiple fields in the services subform, one of which is a drop-down field allowing you to choose from the programs a client has been enrolled in (the list is updated for that client whenever he is enrolled in a new program). The problem details: For one specific record and one specific program area, the program has disappeared from the "programs enrolled" subform and all of the related services have disappeared from the "services" subform for a period of 3 months of data entry. However, other programs and services for this record did not disappear. Questions: Is the disappearance of data a common Access 2003 problem? Are there tests in place that can be run to see if data is disappearing and catch that data? If so, what are they? If there is specific code involved, what is it? What can be done to prevent the disappearing of data (other than using a different database)?

    How to handle this error in lucene: java.lang.AbstractMethodError: org.apache.lucene.store.Directory.listAll()[Ljava/lang/String; at org.apache.lucene.index.SegmentInfos$FindSegmentsFile.run(SegmentInfos.java:568) at org.apache.lucene.index.DirectoryReader.open(DirectoryReader.java:69) at org.apache.lucene.index.IndexReader.open(IndexReader.java:316) at org.apache.lucene.index.IndexReader.open(IndexReader.java:188) I am making a lucene function call but unfortunately it itself calls an abstract method of some class, as is evident from the error above. What is the work around for this? Thanks, --Akhil

  • Traversing/Manipulating new window from parent window with jquery

    - by Anthony
    I found a question already with a possible solution, but I had already tried the method suggested before reading it, and it even says it's inconsistent. So I guess I'm wondering why this doesn't work: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert(imgwindow.find("img").attr("src")); }); The goal is to set the new window's img to the same src as the image that the user clicked to open the new window. But in the above scenario, I'm just trying to tap into the new window to get what it's already-set src. I have imgwin.html already written with a default src for the image, so it should alert that url. Instead I just get undefined. I also tried the following (which should be identical on the back end), but with the same results: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert($("img",imgwindow).attr("src")); }); I even tried variations of wrapping the imgwindow variable in $() in case somehow jquery wasn't picking up on the variable as a DOM element. The only thing I can guess is that since window.open() is a method, jquery doesn't treat it like a DOM element, even though all documentation from basic javascript tutorials treat the variable as both a method to open the window and the pointer to the window's inner DOM.

  • SqlCommandBuilder.DeriveParameters(command) and IsNullable

    - by Andrey
    I have written an O/R database wrapper that generates some wrapper methods for stored procs it reads from the database. Now I need to produce some custom wrapper code if an input parameter of a stored proc is defaulted to NULL. The problem is - I get stored proc parameters using: SqlCommandBuilder.DeriveParameters(command) and it doesn't bring parameter defaults. Is there any way to look up those defaults? Are they stored anywhere in the database? BTW, I'm using SQL Server 2008

  • Character set issues with Oracle Gateways, SQL Server, and Application Express

    - by Brian Deterling
    I am migrating data from a Oracle on VMS that accesses data on SQL Server using heterogeneous services (over ODBC) to Oracle on AIX accessing the SQL Server via Oracle Gateways (dg4msql). The Oracle VMS database used the WE8ISO8859P1 character set. The AIX database uses WE8MSWIN1252. The SQL Server database uses "Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive for Unicode Data, SQL Server Sort Order 52 on Code Page 1252 for non-Unicode Data" according to sp_helpsort. The SQL Server databases uses nchar/nvarchar or all string columns. In Application Express, extra characters are appearing in some cases, for example 123 shows up as %001%002%003. In sqlplus, things look ok but if I use Oracle functions like initcap, I see what appear as spaces between each letter of a string when I query the sql server database (using a database link). This did not occur under the old configuration. I'm assuming the issue is that an nchar has extra bytes in it and the character set in Oracle can't convert it. It appears that the ODBC solution didn't support nchars so must have just cast them back to char and they showed up ok. I only need to view the sql server data so I'm open to any solution such as casting, but I haven't found anything that works. Any ideas on how to deal with this? Should I be using a different character set in Oracle and if so, does that apply to all schemas since I only care about one of them.

  • Oracle performance problem

    - by jreid42
    We are using an Oracle 11G machine that is very powerful; has redundant storage etc. It's a beast from what I have been told. We just got this DB for a tool that when I first came on as a coop had like 20 people using, now its upwards of 150 people. I am the only one working on it :( We currently have a system in place that distributes PERL scripts across our entire data center essentially giving us a sort of "grid" computing power. The Perl scripts run a sort of simulation and report back the results to the database. They do selects / inserts. The load is not very high for each script but it could be happening across 20-50 systems at the same time. We then have multiple data centers and users all hitting the same database with this same approach. Our main problem with this is that our database is getting overloaded with connections and having to drop some. We sometimes have upwards of 500 connections. These are old perl scripts and they do not handle this well. Essentially they fail and the results are lost. I would rather avoid having to rewrite a lot of these as they are poorly written, and are a headache to even look at. The database itself is not overloaded, just the connection overhead is too high. We open a connection, make a quick query and then drop the connection. Very short connections but many of them. The database team has basically said we need to lower the number of connections or they are going to ignore us. Because this is distributed across our farm we cant implement persistent connections. I do this with our webserver; but its on a fixed system. The other ones are perl scripts that get opened and closed by the distribution tool and thus arent always running. What would be my best approach to resolving this issue? The scripts themselves can wait for a connection to be open. They do not need to act immediately. Some sort of queing system? I've been suggested to set up a few instances of a tool called "SQL Relay". Maybe one in each data center. How reliable is this tool? How good is this approach? Would it work for what we need? We could have one for each data center and relay requests through it to our main database, keeping a pipeline of open persistent connections? Does this make sense? Is there any other suggestions you can make? Any ideas? Any help would be greatly appreciated. Sadly I am just a coop student working for a very big company and somehow all of this has landed all on my shoulders (there is literally nobody to ask for help; its a hardware company, everybody is hardware engineers, and the database team is useless and in India) and I am quite lost as what the best approach would be? I am extremely overworked and this problem is interfering with on going progress and basically needs to be resolved as quickly as possible; preferably without rewriting the whole system, purchasing hardware (not gonna happen), or shooting myself in the foot. HELP LOL!

  • How to get the data for intra-day candlestick charts for stocks on eg Nasdaq

    - by Chris
    Hi, For a learning exercise, i'm wanting to create candlestick (stock) graphs for stocks using zedgraph. Now on google finance, i can get daily open-high-low-close data which is perfect for making these graphs, but i'm wanting to create intra-day graphs, eg open-high-low-close data for an hour (or 5 mins, or 1 min even). Is there any way to get that kind of data without having to subscribe to any expensive service? I've heard opentick mentioned in an old SO question, but their site is defunct now. I was thinking of polling google finance once a minute to get the latest stock price, then with an hour's worth of 60 prices, i could then roughly calculate the open-high-low-close, but this is a bit of an estimation and i'm open to other suggestions. Cheers all.

  • How can I listen to multiple Serial Ports asynchronously in C#

    - by Kamiel Wanrooij
    I have an application that listens to a piece of hardware on a USB to Serial converter. My application should monitor more than one serial port at the same time. I loop the serial ports I need to listen to, and create a thread for each port. In the thread I have my data handing routine. When I assign one port, it runs flawlessly. When I listen to the other one, it also works. When I open both ports however, the second port always throws an UnauthorizedAccessException when calling serialPort.Open(). It does not matter in what order I open the ports, the second one always fails. I listen to the ports using serialPort.ReadLine() in a while loop. Can .NET open more than one port at the same time? Can I listen to both? Or should I use another (thread safe?) way to access my serial port events?

  • Disposables, Using & Try/Catch Blocks

    - by Aren B
    Having a mental block today, need a hand verifying my logic isn't fubar'ed. Traditionally I would do file i/o similar to this: FileStream fs = null; // So it's visible in the finally block try { fs = File.Open("Foo.txt", FileMode.Open); /// Do Stuff } catch(IOException) { /// Handle Stuff } finally { if (fs != null) fs.Close(); } However, this isn't very elegant. Ideally I'd like to use the using block to dispose of the filestream when I'm done, however I am unsure about the synergy between using and try/catch. This is how i'd like to implement the above: try { using(FileStream fs = File.Open("Foo.txt", FileMode.Open)) { /// Do Stuff } } catch(Exception) { /// Handle Stuff } However, I'm worried that a premature exit (via thrown exception) from within the using block may not allow the using block to complete execution and clean up it's object. Am I just paranoid, or will this actually work the way I intend it to?
