  • MS Access Crashed an now all Form objects and code modules are missing

    - by owlie
    I was adding a form to our Access 07 db. I copied an existing form to use as a template, renamed it, and saved it. I opened a different form to check something and Access crashed. When I reopened the database it says: "Access has detected that this database is in an inconsistent state, and will attempt to recover the database." etc. When it reopened - all forms and reports were missing. Saved queries remain. The error message states that object recovery failures will be noted in a Recovery Errors table - but this table wasn't created. The links to the be database remained intact. The database is split - I was experimenting with a form on a front-end copy which might have something to do with it. Any ideas what would cause this (I can see loosing recent work - but nixing all form objects?!) And is there any chance of recovery?

  • Is LocalDB supported by Visual Studio 2010 in Entity Framework 5?

    - by Mathias Lykkegaard Lorenzen
    Is LocalDB supported by Visual Studio 2010 in Entity Framework 5, on .NET 4.0? Or am I doing it wrong? I'm getting a "The network path can't be found" issue when instantiating my model container with a connection string for LocalDB. Here's the connection string: var connectionString = "metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string=\"data source=(localdb)\v11.0;initial catalog=fablelane_com_db;integrated security=SSPI;multipleactiveresultsets=True;App=EntityFramework\""; Edit 1 I'm receiving the following error when connecting, more specifically: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server). Edit 2 I just figured out that changing to Visual Studio 11 beta doesn't work either. Still receiving the same error-message.

  • Store #VALUE! #NUM! #REF! in variable.

    - by Ommit
    So a simple version of what I'm trying to do. Say I know there is an error in cell(1,1), furthermore I know it is either #num!, #ref! or #value!, I want to be able to store the respective error message in a variable, so I can print it to a different sheet. This is what I tried and it clearly failed. Sub FindAndPrintErrors dim Store as string If IsError(Range("A1"))) = True Then Store = Range("A1").value 'it breaks here' end if range("B1") = Store end sub I know I can do this but I wonder if there is a better way. Sub FindAndPrintErrors2 dim Store If IsError(Range("A1"))) = True Then temp = Range("A1").value 'it breaks here' if temp = "error 2029" then store = "#num!" ' and so on' end if range("B1") = Store end sub

  • Programmatically find maximum static array size in C++

    - by GuyGreer
    I am curious whether it is possible to determine the maximum size that an array can have in C++. #include <iostream> using namespace std; #define MAX 2000000 int main() { long array[MAX]; cout << "Message" << endl; return 0; } This compiles just fine, but then segfaults as soon as I run it (even though array isn't actually referenced). I know it's the array size too because if I change it to 1000000 it runs just fine. So, is there some define somewhere or some way of having #define MAX MAX_ALLOWED_ARRAY_SIZE_FOR_MY_MACHINE_DEFINED_SOMEWHERE_FOR_ME? I don't actually need this for anything, this question is for curiosity's sake.

  • Exception handling pattern

    - by treefrog
    It is a common pattern I see where the error codes associated with an exception are stored as Static final ints. when the exception is created to be thrown, it is constructed with one of these codes along with an error message. This results in the method that is going to catch it having to look at the code and then decide on a course of action. The alternative seems to be- declare a class for EVERY exception error case Is there a middle ground ? what is the recommended method ?

  • I set a global bug catcher in my application for unhandled exceptions and it is picking up all exceptions

    - by user1632018
    I am trying to figure out why this is happing. In my vb.net application I set a global handler in the ApplicationEvents.vb which I thought would only pick up any unhandled exceptions, although it is picking up every exception that happens in my application whether or not they are handled with try catch blocks. Here is my code in applicationevents Private Sub MyApplication_UnhandledException(ByVal _ sender As Object, ByVal e As _ Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) _ Handles Me.UnhandledException e.ExitApplication = _ MessageBox.Show(e.Exception.Message & _ vbCrLf & "The application has encountered a bug, would you like to Continue?", "An Error has occured.", _ MessageBoxButtons.YesNo, _ MessageBoxIcon.Question) _ = DialogResult.No End Sub In the rest of my application I set normal try catch blocks like this: Try Catch ex as exception End Try Can anyone tell me why this is happening?

  • nested list comprehension using intermediate result

    - by KentH
    I am trying to grok the output of a function which doesn't have the courtesy of setting a result code. I can tell it failed by the "error:" string which is mixed into the stderr stream, often in the middle of a different conversion status message. I have the following list comprehension which works, but scans for the "error:" string twice. Since it is only rescanning the actual error lines, it works fine, but it annoys me I can't figure out how to use a single scan. Here's the working code: errors = [e[e.find('error:'):] for e in err.splitlines() if 'error:' in e] The obvious (and wrong) way to simplify is to save the "find" result errors = [e[i:] for i in e.find('error:') if i != -1 for e in err.splitlines()] However, I get "UnboundLocalError: local variable 'e' referenced before assignment". Blindly reversing the 'for's in the comprehension also fails. How is this done? THanks. Kent

  • JAAS : on Callback ( Interesting based on HTTP headers )

    - by VJS
    I am using NameCallback and PasswordCallback for username and password.For username and password, popup comes on browser and when i enter username ans password, JAAS authenticates my request. On the wireshark, I have seen that 401 Unauthorized message (WWW-Authenticate header)comes and when i enter username/password HTTP request with credentials generate ( with Authorization header) and goes to server. My requirement : I don't want pop up to come.My application on other server having username / password, so once it received 401 then based on some logic it will generate HTTP request with Authorization header / credentials and sent it back. FLow : User - Other Server - My Tomcat5.5 Here on Other Server, nobody is available to enter username/password manually.Application is deployed and it will only generate HTTP request with credential and sent it back to tomcat. Can we have any other callback which behave like this.Need your help.Please provide me feedback as well related to approach.

  • Python 2.6 - I can not write dwords greater than 0x7fffffff into registry using _winreg.SetValueEx()

    - by stasizke
    using regedit.exe I have manually created a key in registry called HKEY_CURRENT_USER/00_Just_a_Test_Key and created two dword values dword_test_1 and dword_test_2 I am trying to write some values into those two keys using following program import _winreg aReg = _winreg.ConnectRegistry(None,_winreg.HKEY_CURRENT_USER) aKey = _winreg.OpenKey(aReg, r"00_Just_a_Test_Key", 0, _winreg.KEY_WRITE) _winreg.SetValueEx(aKey,"dword_test_1",0, _winreg.REG_DWORD, 0x0edcba98) _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) _winreg.CloseKey(aKey) _winreg.CloseKey(aReg) I can write into the first key, dword_test_1, but when I attempt to write into the second, I get following message Traceback (most recent call last): File "D:/src/registry/question.py", line 7, in <module> _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) ValueError: Could not convert the data to the specified type. How do I write the second value 0xfedcba98, or any value greater than 0x7fffffff as a dword value?

  • What's the most performance effective way to have a webbrowser inside a class library ?

    - by Xaqron
    I'm developing a class library. Need some data from internet and this cannot be done with HttpWebRequest in my case so I wanna use WebBrowser component. WebBrowser is used for opening a single page and fetch some data from it, so WebBrowser life-time is very short. Running thread is MTA and no message pump or STA thread is available by default (class library is used by an ASP.NET application). How to create a WebBrowser object, run it with a STA thread, fetch data from a web page and finally dispose it with the least performance impact on the application ? I just need the idea/concept and will find details myself. Thanks guys

  • How do I reference a pointer from a different class?

    - by Justagruvn
    First off, I despise singletons with a passion. Though I should probably be trying to use one, I just don't want to. I want to create a data class (that is instantiated only once by a view controller on loading), and then using a different class, message the crap out of that data instance until it is brimming with so much data, it smiles. So, how do I do that? I made a pointer to the instance of the data class when I instantiated it. I'm now over in a separate view controller, action occurs, and I want to update the initial data object. I think I need to reference that object by way of pointer, but I have no idea how to do that. Yes, I've set properties and getters and setters, which seem to work, but only in the initial view controller class. Peace Love applesauce.

  • How can I start XServer in Linux through apache user triggered by Perl script running in background?

    - by Nikhil
    I am trying to launch MS Office through WINE using a PERL script hosted by apache and and triggered by other application. I am getting the following error message in log files "Application trying to create a window but no driver could not be loaded. Make sure that your X server is running and that $DISPLAY is set correctly". If I run the script directly on shell prompt using root user then WINE starts XServer properly and execute MS MSoffice in addition to that if I set xhost +local:apache on shell prompt then also it works fine. How can I start the XServer from apache user?

  • How to find the remainder of large number division in C++?

    - by Beelzeboul
    Hello, I have a question regarding modulus in C++. What I was trying to do was divide a very large number, lets say for example, M % 2, where M = 54,302,495,302,423. However, when I go to compile it says that the number is to 'long' for int. Then when I switch it to a double it repeats the same error message. Is there a way I can do this in which I will get the remainder of this very large number or possibly an even larger number? Thanks for your help, much appreciated.

  • Why the data binding in this validation example works in WPF?

    - by MartyIX
    I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!
