  • ASP.NET UpdatePanel Time Out

    - by ctrlShiftBryan
    I'm making a request from an UpdatePanel that takes more then 90 seconds. I'm getting this timeout error. "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out." Does anyone know if there is a way to increase the amount of time before the the call times out?

  • Calling CryptUIWizDigitalSign from .NET on x64

    - by Joe Kuemerle
    I am trying to digitally sign files using the CryptUIWizDigitalSign function from a .NET 2.0 application compiled to AnyCPU. The call works fine when running on x86 but fails on x64, it also works on an x64 OS when compiled to x86. Any idea on how to better marshall or call from x64? The Win32exception returned is "Error encountered during digital signing of the file ..." with a native error code of -2146762749. The relevant portion of the code are: [StructLayout(LayoutKind.Sequential)] public struct CRYPTUI_WIZ_DIGITAL_SIGN_INFO { public Int32 dwSize; public Int32 dwSubjectChoice; [MarshalAs(UnmanagedType.LPWStr)] public string pwszFileName; public Int32 dwSigningCertChoice; public IntPtr pSigningCertContext; [MarshalAs(UnmanagedType.LPWStr)] public string pwszTimestampURL; public Int32 dwAdditionalCertChoice; public IntPtr pSignExtInfo; } [DllImport("Cryptui.dll", CharSet=CharSet.Unicode, SetLastError=true)] public static extern bool CryptUIWizDigitalSign(int dwFlags, IntPtr hwndParent, string pwszWizardTitle, ref CRYPTUI_WIZ_DIGITAL_SIGN_INFO pDigitalSignInfo, ref IntPtr ppSignContext); CRYPTUI_WIZ_DIGITAL_SIGN_INFO digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo.dwSize = Marshal.SizeOf(digitalSignInfo); digitalSignInfo.dwSubjectChoice = 1; digitalSignInfo.dwSigningCertChoice = 1; digitalSignInfo.pSigningCertContext = pSigningCertContext; digitalSignInfo.pwszTimestampURL = timestampUrl; digitalSignInfo.dwAdditionalCertChoice = 0; digitalSignInfo.pSignExtInfo = IntPtr.Zero; digitalSignInfo.pwszFileName = filepath; CryptUIWizDigitalSign(1, IntPtr.Zero, null, ref digitalSignInfo, ref pSignContext)); And here is how the SigningCertContext is retrieved (minus various error handling) public IntPtr GetCertContext(String pfxfilename, String pswd) IntPtr hMemStore = IntPtr.Zero; IntPtr hCertCntxt = IntPtr.Zero; IntPtr pProvInfo = IntPtr.Zero; uint provinfosize = 0; try { byte[] pfxdata = PfxUtility.GetFileBytes(pfxfilename); CRYPT_DATA_BLOB ppfx = new CRYPT_DATA_BLOB(); ppfx.cbData = pfxdata.Length; ppfx.pbData = Marshal.AllocHGlobal(pfxdata.Length); Marshal.Copy(pfxdata, 0, ppfx.pbData, pfxdata.Length); hMemStore = Win32.PFXImportCertStore(ref ppfx, pswd, CRYPT_USER_KEYSET); pswd = null; if (hMemStore != IntPtr.Zero) { Marshal.FreeHGlobal(ppfx.pbData); while ((hCertCntxt = Win32.CertEnumCertificatesInStore(hMemStore, hCertCntxt)) != IntPtr.Zero) { if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, IntPtr.Zero, ref provinfosize)) pProvInfo = Marshal.AllocHGlobal((int)provinfosize); else continue; if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, pProvInfo, ref provinfosize)) break; } } finally { if (pProvInfo != IntPtr.Zero) Marshal.FreeHGlobal(pProvInfo); if (hMemStore != IntPtr.Zero) Win32.CertCloseStore(hMemStore, 0); } return hCertCntxt; }

  • Time is updating when a form is not even running

    - by onaclov2000
    A co-worker of mine had downloaded a vb example project a while back to see how to make a call or two, he discovered it today again, and noticed that while sitting in the IDE the time/date is updating automatically when the entire project is not even running. How does this work, we looked around for code but can't find anything giving it away. Any ideas?

  • Best practise - Accessing preferences globally

    - by JK
    User preferences for my app is store in NSUserDefaults. This includes a "theme" preference, which needs to be accessed frequently by multiple classes. I would prefer not to call "[[NSUserDefaults standardUserDefaults] objectForKey:..." repeatedly as it makes for inconcise code and I assume will incur overhead. What is the preferred and most concise method for accessing preferences in any class?

  • Boost any usage

    - by Ockonal
    Hello, how can I insert my own class objects into ptr_map from boost. The objects are templated so I can't use some static typename in the map. So I did: ptr_map<string, any> someMap; My class inherits the boost::noncopyable. someMap.insert("Test", new MyClass()); The error is: error: no matching function for call to ‘boost::ptr_map.

  • ctypes buffer modification

    - by Chris
    Hi, I need to call a c library from my python code. The c library does a lot of image manipulation, so I am passing it image buffers allocated using create_string_buffer. The problem is that I also need to manipulate and change these buffers. What is the best way to reach in and twiddle individual values in my buffers? The buffers are all uint8 buffers. Thanks!

  • Are there any platforms where using structure copy on an fd_set (for select() or pselect()) causes p

    - by Jonathan Leffler
    The select() and pselect() system calls modify their arguments (the 'struct fd_set *' arguments), so the input value tells the system which file descriptors to check and the return values tell the programmer which file descriptors are currently usable. If you are going to call them repeatedly for the same set of file descriptors, you need to ensure that you have a fresh copy of the descriptors for each call. The obvious way to do that is to use a structure copy: struct fd_set ref_set_rd; struct fd_set ref_set_wr; struct fd_set ref_set_er; ... ...code to set the reference fd_set_xx values... ... while (!done) { struct fd_set act_set_rd = ref_set_rd; struct fd_set act_set_wr = ref_set_wr; struct fd_set act_set_er = ref_set_er; int bits_set = select(max_fd, &act_set_rd, &act_set_wr, &act_set_er, &timeout); if (bits_set > 0) { ...process the output values of act_set_xx... } } My question: Are there any platforms where it is not safe to do a structure copy of the struct fd_set values as shown? I'm concerned lest there be hidden memory allocation or anything unexpected like that. (There are macros/functions FD_SET(), FD_CLR(), FD_ZERO() and FD_ISSET() to mask the internals from the application.) I can see that MacOS X (Darwin) is safe; other BSD-based systems are likely to be safe, therefore. You can help by documenting other systems that you know are safe in your answers. (I do have minor concerns about how well the struct fd_set would work with more than 8192 open file descriptors - the default maximum number of open files is only 256, but the maximum number is 'unlimited'. Also, since the structures are 1 KB, the copying code is not dreadfully efficient, but then running through a list of file descriptors to recreate the input mask on each cycle is not necessarily efficient either. Maybe you can't do select() when you have that many file descriptors open, though that is when you are most likely to need the functionality.) There's a related SO question - asking about 'poll() vs select()' which addresses a different set of issues from this question.

  • C: performance of assignments, binary operations, et cetera...

    - by Shinka
    I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

  • run a function when a user clicks on any list element

    - by sova
    This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)

  • Any way to create a hidden main window in C#?

    - by Bill
    I just want a c# application with a hidden main window that will process and respond to window messages. I can create a form without showing it, and can then call Application.Run() without passing in a form, but how can I hook the created form into the message loop? Is there another way to go about this? Thanks in advance for any tips!

  • django url from another template than the one associated with the view-function

    - by dana
    Heyy there, i have an application, and in my urls.py i have something like that: urlpatterns = patterns('', url(r'^profile_view/(?P<id>\d+)/$', profile_view, name='profile_view'),) meaning that the profile_view function has id as a parameter. Now, i want to call that function from another template than the one associated with the def-view that has this url. How should i do that? i have to put two render_to_response to one same function, in order to render the objects from both models? thank you!

  • Patterns for dynamic CMS components (event driven?)

    - by CitrusTree
    Sorry my title is not great, this is my first real punt at moving 100% to OO as I've been procedural for more years than I can remember. I'm finding it hard to understand if what I'm trying to do is possible. Depending on people's thoughts on the 2 following points, I'll go down that route. The CMS I'm putting together is quote small, however focuses very much on different types of content. I could easily use Drupal which I'm very comfortable with, but I want to give myself a really good reasons to move myself into design patterns / OO-PHP 1) I have created a base 'content' class which I wish to be able to extend to handle different types of content. The base class, for example, handles HTML content, and extensions might handle XML or PDF output instead. On the other hand, at some point I may wish to extend the base class for a given project completely. I.e. if class 'content-v2' extended class 'content' for that site, any calls to that class should actually call 'content-v2' instead. Is that possible? If the code instantiates an object of type 'content' - I actually want it to instantiate one of type 'content-v2'... I can see how to do it using inheritance, but that appears to involve referring to the class explicitly, I can't see how to link the class I want it to use instead dynamically. 2) Secondly, the way I'm building this at the moment is horrible, I'm not happy with it. It feels very linear indeed - i.e. get session details get content build navigation theme page publish. To do this all the objects are called 1-by-1 which is all very static. I'd like it to be more dynamic so that I can add to it at a later date (very closely related to first question). Is there a way that instead of my orchestrator class calling all the other classes 1-by-1, then building the whole thing up at the end, that instead each of the other classes can 'listen' for specific events, then at the applicable point jump in and do their but? That way the orchestrator class would not need to know what other classes were required, and call them 1-by-1. Sorry if I've got this all twisted in my head. I'm trying to build this so it's really flexible.

  • R - indirectly calling a matrix using a string

    - by Boris Senderovich
    Example: There is a matrix of data called VE There is a vector of string where the first element is the string VE. I need to indirectly call the string and be able to access data. For example if I need the 6th column of matrix VE then I want to do: Vector[1][,6] Essentially I need R to start reading those string as if they are the matrix names that are already in this page. I need this syntax to be dynamic because I am putting it in a loop.

    - by bitstream
    I have an Oracle package which contains user-defined functions and procedures, including two user-defined functions which are called from SELECT and UPDATE statements. The functions in question are defined before the procedures that call them. This piece of code compiles and works fine on Oracle 10g but won't compile on 9i. The code should work as-is according to Oracle's own documentation. Any idea why it would throw this error on 9i?
