  • How do I get ELMAH to work with SQL Server (permission problems)

    - by Gary McGill
    I've got ELMAH working on my (Cassini) development server, and was quite happy with it, but now that I'm trying to move everything to my production server (IIS7), the honeymoon looks like being over. I've got past the "gotcha" with IIS7, which frankly could have been better highlighted in the documentation, and if I just use the in-memory log then it works. However, I'm trying to get it to use the SQL Server log (as I do on my development system), and I'm getting an error along the lines of: The EXECUTE permission was denied on the object ELMAH_GetErrorsXml Well, fine. I know how to grant database permissions, but I'm really struggling to understand which user and which stored procs/tables I need to grant access to. The thing that's really confusing me is that I didn't have to do anything like this to get it to work on my development server. The only difference I can see is that on my development server it seems to connect as NT AUTHORITY\IUSR, whereas on my production server it seems to connect as NT AUTHORITY\NETWORK SERVICE. (It's just using a trusted connection so I've not explicitly configured it to do that - I presume it's to do with the web server). UPDATE: I've since established that because I'm using Cassini, it was actually logging in as me (an admin) and not IUSR, which explains why I didn't get any permission problems. On my development server, the IUSR account is a member of the public database role, and has access to the required database (again as "public"). There's no explicit granting of object-level permissions. [See update above - this is irrelevant]. On my production server, I've added NETWORK SERVICE in exactly the same way (public database role, explicit access to the database as "public"). Yet, I get this permission error. Why?!! [See update above - the only reason I don't get a permission error is because I'm running as an admin]. And, of course, if the fact that it works locally is just "luck", I will need to know which SPs/tables to grant access to. My guess would be all 3 SPs and not the table, but it would be good (again) to see some documentation that makes this explicit.

  • Hibernate proxy serialization and receive on client side.

    - by Bubba88
    I lack understanding of how does the generated proxy class object (CGLib enhanced POJO) is transferred to the remote client and still pertains its ability to generate Lazy Init. Exceptions. Does that mean that there is some kind of contract that all the transferred objects of some kind of class (a proxy) will be reinstantiated as proxies again? Where does the client obtain those generated classes? Sorry, but I totally do not understand.

  • Problem in retrieving the ini file through web page

    - by MalarN
    Hi All, I am using an .ini file to store some values and retrieve values from it using the iniparser. When I give (hardcode) the query and retrive the value through the command line, I am able to retrive the ini file and do some operation. But when I pass the query through http, then I am getting an error (file not found), i.e., the ini file couldn't be loaded. Command line : int main(void) { printf("Content-type: text/html; charset=utf-8\n\n"); char* data = "/cgi-bin/set.cgi?pname=x&value=700&url=http://IP/home.html"; //perform some operation } Through http: .html function SetValue(id) { var val; var URL = window.location.href; if(id =="set") { document.location = "/cgi-bin/set.cgi?pname="+rwparams+"&value="+val+"&url="+URL; } } .c int * Value(char* pname) { dictionary * ini ; char *key1 = NULL; char *key2 =NULL; int i =0; int val; ini = iniparser_load("file.ini"); if(ini != NULL) { //key for fetching the value key1 = (char*)malloc(sizeof(char)*50); if(key1 != NULL) { strcpy(key1,"ValueList:"); key2 = (char*)malloc(sizeof(char)*50); if(key2 != NULL) { strcpy(key2,pname); strcat(key1,key2); val = iniparser_getint(ini, key1, -1); if(-1 == val || 0 > val) { return 0; } } else { //error free(key1); return; } } else { printf("ERROR : Memory Allocation Failure "); return; } } else { printf("ERROR : .ini File Missing"); return; } iniparser_freedict(ini); free(key1); free(key2); return (int *)val; } void get_Value(char* pname,char* value) { int result =0; result = Value(pname); printf("Result : %d",result); } int main(void) { printf("Content-type: text/html; charset=utf-8\n\n"); char* data = getenv("QUERY_STRING"); //char* data = "/cgi-bin/set.cgi?pname=x&value=700&url=http://10.50.25.40/home.html"; //Parse to get the values seperately as parameter name, parameter value, url //Calling get_Value method to set the value get_Value(final_para,final_val); } * file.ini * [ValueList] x = 100; y = 70; When the request is sent through html page, I am always getting .ini file missing. If directly the request is sent from C file them it works fine. How to resolve this?

Can somebody clue me in? This code used to work.

  • Naming Suggestions For A Function Providing Method Chaining In A Different Way

    - by sid3k
    I've coded an experimental function which makes passed objects chainable by using high order functions. It's name is "chain" for now, and here is a usage example; chain("Hello World") (print) // evaluates print function by passing "Hello World" object. (console.log,"Optional","Parameters") (returnfrom) // returns "Hello World" It looks lispy but behaves very different since it's coded in a C based language, I don't know if there is a name for this idiom and I couldn't any name more suitable than "chain". Any ideas, suggestions?

  • How do you set the twitter user location in JTwitter?

    - by Gregg Reno
    I'm building some basic Twitter functionality into my app, and am using the JTwitter JAR to read and set status. It looks like there is a User class that can be used to set the location, but I just can't figure out how to set it with my GPS coordinates once I've got my Twitter object. Has anyone been able to set the user.location property using JTwitter? Thanks, -Gregg

  • odd resharper indentation formatting for opject intializers

    - by bitbonk
    For some strange reason when I have nested object intializers it always gets the last '}' wrong. It is not indented at all as shown in the following example: namespace MyNameSpace { internal static class MyClass { static MyClass() { var bla = new Bla { Name = "Bla" }; bla.Blub = new Blub { Name = "Blub", Blap = new Blap { Name = "Blap", Visible = true }, Blob = new Blob { Name = "Blob" }, Blib = new Blib { Blep = new Heater { Name = "Bleb" }, Id = 1, Blap = new Blap { Name = "Blap" } } // <---- wrong !!! }; } } } Any idea what I can do against it ?

    I'm using Cumcumber + capybara + selenium to run automated testing, but I'm having trouble finding a way to assert that a javascript alert is displayed. This question seems has a solution with selenium, but I can't figure out how to call the selenium object using Capybara. Is there a simple way to test for alerts using Capybara? Or is there a workaround?

  • WP7 silverlight custom control using popup

    - by Miloud B.
    Hi guys, I'm creating a custom datepicker, I have a textbox, once clicked it opens a calendar within a popup. What I want to do is change the size of the popup so it shows my whole calendar, but I can't manage to change it..., I've tried using Height, Width, MinHeight, MinWidth... but it doesn't work, the popup keep showing with a fixed size. The thing is that my popup's parent property isn't evaluated since it has expression issues (according to debugger), so I'm sure my popup's parent isn't the main screen( say layout grid). How can I for example make my popup open within a specific context ? This part of my code isn't XAML, it's C# code only and it looks like: using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.Windows.Controls.Primitives; namespace CalendarBranch.components { public class wpDatePicker:TextBox { private CalendarPopup calendar; private Popup popup; public wpDatePicker() { this.calendar = new CalendarPopup(); this.popup = new Popup(); this.popup.Child = this.calendar; this.popup.Margin = new Thickness(0); this.MouseLeftButtonUp += new MouseButtonEventHandler(wpDatePicker_MouseLeftButtonUp); this.calendar.onDateSelect += new EventHandler(onDateSelected); this.IsReadOnly = true; } protected void wpDatePicker_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { this.popup.Height = this.calendar.Height; this.popup.Width = this.calendar.Width; this.popup.HorizontalAlignment = HorizontalAlignment.Center; this.popup.VerticalAlignment = VerticalAlignment.Center; this.popup.HorizontalOffset = 0; this.popup.VerticalOffset = 0; this.popup.MinHeight = this.calendar.Height; this.popup.MinWidth = this.calendar.Width; this.popup.IsOpen = true; } private void onDateSelected(Object sender, EventArgs ea) { this.Text = this.calendar.SelectedValue.ToShortDateString(); this.popup.IsOpen = false; } } } PS: the class Calendar is simply a UserControl that contains a grid with multiple columns, HyperLinkButtons and TextBlocks, so nothing special. Thank you in advance guys ;) Cheers Miloud B.

  • OpenGL 2D Texture Mapping problem.

    - by gutsblow
    Hi there, I am relatively new to OpenGL and I am having some issues when I am rendering an image as a texture for a QUAD which is as the same size of the image. Here is my code. I would be very grateful if someone helps me to solve this problem. The image appears way smaller and is squished. (BTW, the image dimensions are 500x375). glGenTextures( 1, &S_GLator_InputFrameTextureIDSu ); glBindTexture(GL_TEXTURE_2D, S_GLator_InputFrameTextureIDSu); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); glTexImage2D( GL_TEXTURE_2D, 0, 4, S_GLator_EffectCommonData.mRenderBufferWidthSu, S_GLator_EffectCommonData.mRenderBufferHeightSu, 0, GL_RGBA, GL_UNSIGNED_BYTE, dataP); glBindTexture(GL_TEXTURE_2D, S_GLator_InputFrameTextureIDSu); glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, S_GLator_EffectCommonData.mRenderBufferWidthSu, S_GLator_EffectCommonData.mRenderBufferHeightSu, GL_RGBA, GL_UNSIGNED_BYTE, bufferP); //set the matrix modes glMatrixMode( GL_PROJECTION ); glLoadIdentity(); //gluPerspective( 45.0, (GLdouble)widthL / heightL, 0.1, 100.0 ); glOrtho (0, 1, 0, 1, -1, 1); // Set up the frame-buffer object just like a window. glViewport( 0, 0, widthL, heightL ); glDisable(GL_DEPTH_TEST); glClearColor( 0.0f, 0.0f, 0.0f, 0.0f ); glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT ); glMatrixMode( GL_MODELVIEW ); glLoadIdentity(); glBindTexture( GL_TEXTURE_2D, S_GLator_InputFrameTextureIDSu ); //Render the geometry to the frame-buffer object glBegin(GL_QUADS); //input frame glColor4f(1.f,1.f,1.f,1.f); glTexCoord2f(0.0f,0.0f); glVertex3f(0.f ,0.f ,0.0f); glTexCoord2f(1.0f,0.0f); glVertex3f(1.f ,0.f,0.0f); glTexCoord2f(1.0f,1.f); glVertex3f(1.f ,1.f,0.0f); glTexCoord2f(0.0f,1.f); glVertex3f(0.f ,1.f,0.0f); glEnd();

  • Boo: Explicitly specifying the type of a hash

    - by Kiv
    I am new to Boo, and trying to figure out how to declare the type of a hash. When I do: myHash = {} myHash[key] = value (later) myHash[key].method() the compiler complains that "method is not a member of object". I gather that it doesn't know what type the value in the hash is. Is there any way I can declare to the compiler what type the keys and values of the hash are so that it won't complain?

    I'm trying to display the Baseline Start, Finish, Cost, and Work values for a ResourceAssignment, but cannot seem to find any methods on the ResourceAssignment object that would provide this information. Anybody know if this is possible? I know the information is stored because I can see it in MS Project, and I can see it in the XML version of the project file. Just can't see in the API where to get access to it.

  • How to define and use Python generators appropriately

    - by Morlock
    I want to define a generator from a list that will output the elements one at a time, then use this generator object in an appropriate manner. a = ["Hello", "world", "!"] b = (x for x in a) c = next(b, None) while c != None: print c, c = next(b, None) Is there anything wrong or improvable with the while approach here? Is there a way to avoid having to assign 'c' before the loop? Thanks!

  • Problems using wxWidgets (wxMSW) within multiple DLL instances

    Preface I'm developing VST-plugins which are DLL-based software modules and loaded by VST-supporting host applications. To open a VST-plugin the host applications loads the VST-DLL and calls an appropriate function of the plugin while providing a native window handle, which the plugin can use to draw it's GUI. I managed to port my original VSTGUI code to the wxWidgets-Framework and now all my plugins run under wxMSW and wxMac but I still have problems under wxMSW to find a correct way to open and close the plugins and I am not sure if this is a wxMSW-only issue. Problem If I use any VST-host application I can open and close multiple instances of one of my VST-plugins without any problems. As soon as I open another of my VST-plugins besides my first VST-plugin and then close all instances of my first VST-plugin the application crashes after a short amount of time within the wxEventHandlerr::ProcessEvent function telling me that the wxTheApp object isn't valid any longer during execution of wxTheApp-FilterEvent (see below). So it seems to be that the wxTheApp objects was deleted after closing all instances of the first plugin and is no longer available for the second plugin. bool wxEvtHandler::ProcessEvent(wxEvent& event) { // allow the application to hook into event processing if ( wxTheApp ) { int rc = wxTheApp->FilterEvent(event); if ( rc != -1 ) { wxASSERT_MSG( rc == 1 || rc == 0, _T("unexpected wxApp::FilterEvent return value") ); return rc != 0; } //else: proceed normally } .... } Preconditions 1.) All my VST-plugins a dynamically linked against the C-Runtime and wxWidgets libraries. With regard to the wxWidgets forum this seemed to be the best way to run multiple instances of the software side by side. 2.) The DllMain of each VST-Plugin is defined as follows: // WXW #include "wx/app.h" #include "wx/defs.h" #include "wx/gdicmn.h" #include "wx/image.h" #ifdef __WXMSW__ #include <windows.h> #include "wx/msw/winundef.h" BOOL APIENTRY DllMain ( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: { wxInitialize(); ::wxInitAllImageHandlers(); break; } case DLL_THREAD_ATTACH: break; case DLL_THREAD_DETACH: break; case DLL_PROCESS_DETACH: wxUninitialize(); break; } return TRUE; } #endif // __WXMSW__ class Application : public wxApp {}; IMPLEMENT_APP_NO_MAIN(Application) Question How can I prevent this behavior respectively how can I properly handle the wxTheApp object if I have multiple instances of different VST-plugins (DLL-modules), which are dynamically linked against the C-Runtime and wxWidgets libraries? Best reagards, Steffen
