  • Using WPF class in a web application, problem with hosting permission

    - by tanathos
    I'm developing a DLL that uses WPF classes to make image manipulation. It works fine in my local environment, but when I try to use it in an hosted web site I retrieve this error: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed. exactly when I try to call the EndInit() of a BitmapImage object: BitmapImage originalImage = new BitmapImage(); originalImage.BeginInit(); originalImage.CacheOption = BitmapCacheOption.OnLoad; originalImage.UriSource = new Uri(physical_imagepath); originalImage.EndInit(); Any suggestion?

  • C# check if a COM (Serial) port is already open

    - by TK
    Is there an easy way of programmatically checking if a serial COM port is already open/being used? Normally I would use: try { // open port } catch (Exception ex) { // handle the exception } However, I would like to programatically check so I can attempt to use another COM port or some such.

  • Check if server exists

    - by buhtla
    Here is the problem. User can enter server name and connection string for database. If server is not accessible (wrong address, firewalls or any other issue), I want to be aware of this as quickly as possible. If I'm using sqlConnection and try to connect to a non-accessible server this takes very long (I think more than 1 minute!). This has nothing to do with connection timeout btw so setting this property won't help. My idea is to first try to ping server and if I get response (which means server is accessible from the point of application), than proceed with sqlConnection. If there is no response from ping, operation is aborted and user is properly notified. Is there any better way of doing this? Any idea would be welcome.

  • How can i check if key is pressed during click event with jquery?

    - by daniel smith
    Hi, I would like to catch a click event with jquery and be able to tell if a key was pressed at the same time so i can fork within the callback function based on the keypress. for example: $("button").click(function() { if([KEYPRESSED WHILE CLICKED]) { do something... } else { do something different... } }); Does anyone know if this is possible at all or how it can be done if it is possible?

  • What is a good way of checking to see if a particular user may access a particular file?

    - by Rising Star
    I am working on application which runs as a special unprivileged user. I would like to be able to easily check to see if the user can read a given file. It seems like this should be easy, even when I go into the file in Windows Explorer and see that the read permission is checked, it sometimes seems that there is still something preventing the user from reading the file (such as a parent directory that the user cannot browse) when I try to read it as the user programmatically. The user has no console logon permission, so I can't just log in as the user and try to read the file. So... If I want to know, "Does UserBob have access to file c:\specialPath\specialFile, what is an easy way to find out? BTW, my environment is Windows Server 2003.

  • eclipse wont include/identify user .h files and .o files

    - by bks
    i'm new to eclipse CDT, and try to use an existing .o file that was supplied with the proper .h file. eclipse just wont include it in the compilation process. i tryed drag&drop to the eclipse project browser, and the files did show there, but no use, still "No such file: No such file or directory". i tryed defining the .o file in the: project properties tool settings MinGW C Linker Miscellaneous other objects. didn't work either. as for the header file, i did try a workaround: created a new file in the project and named it after the file i want to include as header, then copied the content. and yet, the compiler/linker didn't recognize the object file. perhaps you can help?thank you

  • Managing PHP processes on Windows 7 (with WAMP)

    - by Andrea
    Is there a way to manage (especially list and kill) long-running PHP processes on a Windows 7 system set up with WAMP? Every once in a while, I'll accidentally throw an infinite loop into a PHP process and want to kill it. Right now, all I can think to do is to restart all my WAMP services but sometimes the PHP processes manage to survive right through the restart, i.e., I still see them outputting to logs even after WAMP's restarted. And if the process isn't logging, then I have no way at all to know when/if it's been killed. Not to mention, this will wipe out everything I'm doing with WAMP, not just a single process. I don't seem to see anything relevant in the Windows Task Manager, but maybe I'm missing something.

  • Writing a line in a JTextArea from another class

    - by Christopher Nastovski
    I'm trying to use a Method in my class 'Visual' to write a line of code into a JTextArea and it prints when I call it from 'Visual' but when I call it from 'Login' It only prints Text into the Console, not to the TextArea. private static Visual Visual; Visual.WriteLine("I'm sorry, your username or password is incorrect. Please try again."); or private static Visual Visual = new Visual(); Visual.WriteLine("I'm sorry, your username or password is incorrect. Please try again."); Dont work form 'Login' But, WriteLine("Test"); works from 'Visual', the class that the method is in. Here's the method in 'Visual' public void WriteLine(String Text) { System.out.println(Text); SystemFeed.append(Text.toString() + "\n"); SystemFeed.setCaretPosition(SystemFeed.getDocument().getLength()); }

  • C++ Why am I unable to use an enum declared globally outside of the class it was declared in?

    - by VGambit
    Right now, my project has two classes and a main. Since the two classes inherit from each other, they are both using forward declarations. In the first object, right underneath the #include statement, I initialize two enums, before the class definition. I can use both enums just fine inside that class. However, if I try to use those enums in the other class, which inherits from the first one, I get an error saying the enum has not been declared. If I try to redefine the enum in the second class, I get a redefinition error. I have even tried using a trick I just read about, and putting each enum in its own namespace; that didn't change anything.

  • Array index is not accessable because it is Friend

    - by user3738194
    I am getting and error when I bring my code into another project. In a blank project it works fine, I really have no idea how to get around it, here is the error Error 1 'System.Data.Index' is not accessible in this context because it is 'Friend'. Dim DataString As String = txtAdvancedCommand.Text ' Create an array containing from each letter in Textbox Dim charArray() As Char = DataString.ToCharArray For index = 0 To charArray.GetUpperBound(0) <-----ERROR on word index Try 'Now lets send the data If SerialPort.IsOpen Then SerialPort.Write(charArray(index) & vbCrLf) <-----ERROR on word index Else ConnectSerial() SerialPort.Write(charArray(index) & vbCrLf) <-----ERROR on word index End If Catch e As Exception txtLog.AppendText(e.Message & vbCrLf) End Try Next now the project I am bringing into has a DLL and I suspect it has something to do with it, I cannot get the source code to the DLL so is there another way around this?

  • Undelete a contact in outlook

    - by Alister
    I have an application written in Delphi that adds / updates contacts in outlook. The problem I'm having is that if the contact has been deleted in Outlook, the code still finds the contact and updates it - and the contact still remains deleted. Is there a way I can determine if the contact is deleted or undelete the contact? Roughly the code looks something like: OutlookApp := CreateOleObject('Outlook.Application'); Mapi := OutlookApp.GetNameSpace('MAPI'); //..... try if ContactOutlookEntryID.AsString <> '' then aContact := Mapi.GetItemFromID(ContactOutlookEntryID.AsString); except end; //try to locate the contact if they have been synchro'd before if VarIsEmpty(aContact) then //if not found aContact := Contacts.Items.Add(2); //add a new contact to outlook aContact.LastName := ContactSurname.AsString; //.....

  • How to quit / terminate / stop a j2me midlet?

    - by hsmit
    Surprisingly terminating a midlet doesn't work in my application. Maybe it is because I'm using Threads, but destroyApp() and notifyDestroyed() are not sufficient. Take for example the following code: protected void destroyApp(boolean arg0) throws MIDletStateChangeException { System.out.println("destroying"); notifyDestroyed(); } protected void startApp() throws MIDletStateChangeException { try { // init modules controller.initialize(); }catch (Exception e) { viewer.showAlert("error in startApp() init controller"); destroyApp(true); } }

  • How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

    - by Diogo K.
    I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

  • vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

    - by phill
    I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()
