  • error C2065: 'CComQIPtr' : undeclared identifier

    - by Ken Smith
    I'm still feeling my way around C++, and am a complete ATL newbie, so I apologize if this is a basic question. I'm starting with an existing VC++ executable project that has functionality I'd like to expose as an ActiveX object (while sharing as much of the source as possible between the two projects). I've approached this by adding an ATL project to the solution in question, and in that project have referenced all the .h and .cpp files from the executable project, added all the appropriate references, and defined all the preprocessor macros. So far so good. But I'm getting a compiler error in one file (HideDesktop.cpp). The relevant parts look like this: #include "stdafx.h" #define WIN32_LEAN_AND_MEAN #include <Windows.h> #include <WinInet.h> // Shell object uses INTERNET_MAX_URL_LENGTH (go figure) #if _MSC_VER < 1400 #define _WIN32_IE 0x0400 #endif #include <atlbase.h> // ATL smart pointers #include <shlguid.h> // shell GUIDs #include <shlobj.h> // IActiveDesktop #include "stdhdrs.h" struct __declspec(uuid("F490EB00-1240-11D1-9888-006097DEACF9")) IActiveDesktop; #define PACKVERSION(major,minor) MAKELONG(minor,major) static HRESULT EnableActiveDesktop(bool enable) { CoInitialize(NULL); HRESULT hr; CComQIPtr<IActiveDesktop, &IID_IActiveDesktop> pIActiveDesktop; // <- Problematic line (throws errors 2065 and 2275) hr = pIActiveDesktop.CoCreateInstance(CLSID_ActiveDesktop, NULL, CLSCTX_INPROC_SERVER); if (!SUCCEEDED(hr)) { return hr; } COMPONENTSOPT opt; opt.dwSize = sizeof(opt); opt.fActiveDesktop = opt.fEnableComponents = enable; hr = pIActiveDesktop->SetDesktopItemOptions(&opt, 0); if (!SUCCEEDED(hr)) { CoUninitialize(); // pIActiveDesktop->Release(); return hr; } hr = pIActiveDesktop->ApplyChanges(AD_APPLY_REFRESH); CoUninitialize(); // pIActiveDesktop->Release(); return hr; } This code is throwing the following compiler errors: error C2065: 'CComQIPtr' : undeclared identifier error C2275: 'IActiveDesktop' : illegal use of this type as an expression error C2065: 'pIActiveDesktop' : undeclared identifier The two weird bits: (1) CComQIPtr is defined in atlcomcli.h, which is included in atlbase.h, which is included in HideDesktop.cpp; and (2) this file is only throwing these errors when it's referenced in my new ATL/AX project: it's not throwing them in the original executable project, even though they have basically the same preprocessor definitions. (The ATL AX project, naturally enough, defines _ATL_DLL, but I can't see where that would make a difference.) My current workaround is to use a normal "dumb" pointer, like so: IActiveDesktop *pIActiveDesktop; HRESULT hr = ::CoCreateInstance(CLSID_ActiveDesktop, NULL, // no outer unknown CLSCTX_INPROC_SERVER, IID_IActiveDesktop, (void**)&pIActiveDesktop); And that works, provided I remember to release it. But I'd rather be using the ATL smart stuff. Any thoughts?

  • PDF permissions management with ASP.NET - Timeout Issue

    - by Ryan Smith
    I have a website that has several PDF files. I need to have quite a few of them locked down with the standard ASP.NET authentication (in a folder with web.config that denies anonymous users). I set PDF files to get handled by the ASP.NET worker process and added: <add type="System.Web.StaticFileHandler" path="*.pdf" verb="*" /> to my web.config, but for some reason they hang when downloading. I've seen this issue before on an old server, and for the live of me I can't remember what I did to solve it. Does anyone have any idea? Thanks.

  • SQL Server: Clustering by timestamp; pros/cons

    - by Ian Boyd
    I have a table in SQL Server, where i want inserts to be added to the end of the table (as opposed to a clustering key that would cause them to be inserted in the middle). This means I want the table clustered by some column that will constantly increase. This could be achieved by clustering on a datetime column: CREATE TABLE Things ( ... CreatedDate datetime DEFAULT getdate(), [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (CreatedDate) ) But I can't guaranteed that two Things won't have the same time. So my requirements can't really be achieved by a datetime column. I could add a dummy identity int column, and cluster on that: CREATE TABLE Things ( ... RowID int IDENTITY(1,1), [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (RowID) ) But you'll notice that my table already constains a timestamp column; a column which is guaranteed to be a monotonically increasing. This is exactly the characteristic I want for a candidate cluster key. So I cluster the table on the rowversion (aka timestamp) column: CREATE TABLE Things ( ... [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (timestamp) ) Rather than adding a dummy identity int column (RowID) to ensure an order, I use what I already have. What I'm looking for are thoughts of why this is a bad idea; and what other ideas are better. Note: Community wiki, since the answers are subjective.

  • What is the fastest collection in c# to implement a prioritizing queue?

    - by Nathan Smith
    I need to implement a queue for messages on a game server so it needs to as fast as possible. The queue will have a maxiumem size. I need to prioritize messages once the queue is full by working backwards and removing a lower priority message (if one exists) before adding the new message. The appliation is asynchronous so access to the queue needs to be locked. I'm currently implementing it using a LinkedList as the underlying storage but have concerns that searching and removing nodes will keep it locked for too long. Heres the basic code I have at the moment: public class ActionQueue { private LinkedList<ClientAction> _actions = new LinkedList<ClientAction>(); private int _maxSize; /// <summary> /// Initializes a new instance of the ActionQueue class. /// </summary> public ActionQueue(int maxSize) { _maxSize = maxSize; } public int Count { get { return _actions.Count; } } public void Enqueue(ClientAction action) { lock (_actions) { if (Count < _maxSize) _actions.AddLast(action); else { LinkedListNode<ClientAction> node = _actions.Last; while (node != null) { if (node.Value.Priority < action.Priority) { _actions.Remove(node); _actions.AddLast(action); break; } } } } } public ClientAction Dequeue() { ClientAction action = null; lock (_actions) { action = _actions.First.Value; _actions.RemoveFirst(); } return action; } }

  • How to sed search and replace without changing ownership

    - by Ian
    I found this command line search and replace example: find . -type f -print0 | xargs -0 sed -i 's/find/replace/g' It worked fine except it changed the date and file ownership on EVERY file it searched through, even those that did not contain the search text. What's a better solution to this task? Thanks.

  • Visual Studio ReportViewer repeating data block on every page

    - by muhan
    I am using Reportviewer to generate a sales invoice to be printed by the user. How can I get databound fields to be printed on every page of a multi page invoice? The invoice is printed on a pre-printed form. I want the printed form to look roughly like: page 1 customer john smith 123 main st. city, CA 90000 some item1 $100 some item2 $150 some item3 $150 page 2 customer john smith 123 main st. city, CA 90000 some item4 $500 some item5 $250 some item6 $950 Total $2100 Using 1 list which contains databound textbox fields for the customer info, and a table for the items. The problem is if there are many items such that the items flow over to page 2, the next page only contains items, and not the customer info which needs to be printed on second page as well. I tried using page header, but I can't use databound items in page header. Please Help!

  • Handling XMLHttpRequest to call external application

    - by Ian
    I need a simple way to use XMLHttpRequest as a way for a web client to access applications in an embedded device. I'm getting confused trying to figure out how to make something thin and light that handles the XMLHttpRequests coming to the web server and can translate those to application calls. The situation: The web client using Ajax (ExtJS specifically) needs to send and receive asynchronously to an existing embedded application. This isn't just to have a thick client/thin server, the client needs to run background checking on the application status. The application can expose a socket interface, with a known set of commands, events, and configuration values. Configuration could probably be transmitted as XML since it comes from a SQLite database. In between the client and app is a lighttpd web server running something that somehow handles the translation. This something is the problem. What I think I want: Lighttpd can use FastCGI to route all XMLHttpRequest to an external process. This process will understand HTML/XML, and translate between that and the application's language. It will have custom logic to simulate pushing notifications to the client (receive XMLHttpRequest, don't respond until the next notification is available). C/C++. I'd really like to avoid installing Java/PHP/Perl on an embedded device. So I'll need more low level understanding. How do I do this? Are there good C++ libraries for interpreting the CGI headers and HTML so that I don't have to do any syntax processing, I can just deal with the request/response contents? Are there any good references to exactly what goes on, server side, when handling the XMLHttpRequest and CGI interfaces? Is there any package that does most of this job already, or will I have to build the non-HTTP/CGI stuff from scratch? Thanks for any help! I am really having trouble learning about the server side of these technologies.

  • All words in a trie data-structure

    - by John Smith
    I'm trying to put all words in a trie in a string, a word is detonated by the eow field being true for a certain character in the trie data structure, hence a trie can could have letters than lead up to no word, for ex "abc" is in the trie but "c"'s eow field is false so "abc" is not a word Here is my Data structure struct Trie { bool eow; //when a Trie field isWord = true, hence there is a word char letter; Trie *letters[27]; }; and here is my attemped print-all function, basically trying to return all words in one string seperated by spaces for words string printAll( string word, Trie& data) { if (data.eow == 1) return word + " "; for (int i = 0; i < 26; i++) { if (data.letters[i] != NULL) printAll( word + data.letters[i]->letter, *(data.letters[i])); } return ""; } Its not outputting what i want, any suggestions?

  • how to change string values in dictionary to int values

    - by tom smith
    I have a dictionary such as: {'Sun': {'Satellites': 'Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus,Neptune,Ceres,Pluto,Haumea,Makemake,Eris', 'Orbital Radius': '0', 'Object': 'Sun', 'RootObject': 'Sun', 'Radius': '20890260'}, 'Earth': {'Period': '365.256363004', 'Satellites': 'Moon', 'Orbital Radius': '77098290', 'Radius': '63710.41000.0', 'Object': 'Earth'}, 'Moon': {'Period': '27.321582', 'Orbital Radius': '18128500', 'Radius': '1737000.10', 'Object': 'Moon'}} I am wondering how to change just the number values to ints instead of strings. def read_next_object(file): obj = {} for line in file: if not line.strip(): continue line = line.strip() key, val = line.split(": ") if key in obj and key == "Object": yield obj obj = {} obj[key] = val yield obj planets = {} with open( "smallsolar.txt", 'r') as f: for obj in read_next_object(f): planets[obj["Object"]] = obj print(planets)

  • Use LINQ and lambdas to put string in proper case

    - by Tobias Funke
    I have this function called ProperCase that takes a string, then converts the first letter in each word to uppercase. So ProperCase("john smith") will return "John Smith". Here is the code: public string ProperCase(string input) { var retVal = string.Empty; var words = input.Split(' '); foreach (var word in words) { if (word.Length == 1) { retVal += word.ToUpper(); } else if (word.Length > 1) { retVal += word.Substring(0, 1).ToUpper() + word.Substring(1).ToLower(); } retVal += ' '; } if (retVal.Length > 0) { retVal = retVal.Substring(0, retVal.Length - 1); } return retVal; } This code workds perfectly, but I'm pretty sure I can do it more elegantly with LINQ and lambdas. Can some please show me how?

  • My app crashes after multiple rotates

    - by Ian Rae
    My app is crashing when I try and rotate it more than a couple of times. I first thought it was just the iPhone Simulator, so I loaded the app onto an iPod touch, and it crashed after fewer rotates in a row. I suspect it's a memory leak in one of my rotate methods. The only place I can think that the crash is being caused is in willRotateToInterfaceOrientation:duration:. The only two methods related to rotate that I've added/extended are shouldAutorotateToInterfaceOrientation: and willRotateToInterfaceOrientation:duration and I don't think it's the first because it only contains the two words: return YES;. Here is my willRotateToInterfaceOrientation:duration: method so you can review it and see where the possible memory leak is. -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration { UIFont *theFont; if ((orientation == UIInterfaceOrientationLandscapeLeft) || (orientation == UIInterfaceOrientationLandscapeRight)) { theFont = [yearByYear.font fontWithSize:16.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(460.0f, 635.0f)]; } else { theFont = [yearByYear.font fontWithSize:10.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(300.0f, 460.0f)]; } [theFont release]; } yearByYear is a UITextView theview is a UIScrollView if anyone has any idea of why my app is crashing, I would be greatly appreciative.

  • Office Automation Libraries

    - by Ian
    Some time ago I posted about a question about reading Excel files as a server process, to get around the tighter restrictions Microsoft have been applying on Office Automation. I now need to extend this, by finding methods/libraries to read other sorts of Office files in an automated way on a server. The applications I'm interested in are Word, Powerpoint, Project and to a lesser extent Word and Visio. I need to be able to support 97-2003 office files, and the newer open xml formats (e.g. xlsx, docx) at a very least. With regards to Word integration, I also need to be able to handle writing/reading RTF text. If anyone has any suggestions I'd be pleased to hear them. Thanks

  • Can't find .Net 2.0 XML Schema

    - by Zach Smith
    I'm currently setting up an application config for a WPF application written in .Net 4.0. The connection string in the app.config is encrypted like so: <connectionStrings configProtectionProvider="DataProtectionConfigurationProvider"> <EncryptedData> <CipherData> <CipherValue>CypherValue</CipherValue> </CipherData> </EncryptedData> </connectionStrings> To use the EncryptedData element I need to include the XMLNS "http://schemas.microsoft.com/.NetConfiguration/v2.0". Attempting to include it produces an error as the schema cannot be found. Is there a way to include the schema or perhaps a different element I could use instead of EncryptedData?

  • IE8 CSS Table Effect

    - by Ian
    I've been trying to make this cross browser (specifically IE), but I do not want to use tables. I will not be able to specify the container width with CSS because its contents (the image) will dynamically change with Javascript, so I need the container to 'auto-size' horizontally. The desired effect would be a centered image with two sets of text (one of the left and one of the left) directly underneath the image, aligned to it's inner edges. Example (Doesn't work on IE): http://pastehtml.com/view/19pbyw9.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> #container { display:table; } </style> </head> <body> <center> <div id="container"> <img src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" alt="" /><br /> <span style="float: left;">test</span> <span style="float: right; text-align: right;">test2</span> </div> </center> </body> </html>

  • "Look" of page changes a bit after uploading it to IIS - looks good on computer same IE8

    - by J Smith
    No it's not a path issue...or else the site won't have a design. The website looks fine if I open it with IE8 in my computer. But after I upload it to IIS 6.0 two things change on positioning. I see a rendering problem. But if I open it with IE 8.0 on my machine it looks good, but opening it when uploaded to IIS , it changes a bit. Same exact files. Same browser, same computer. The only different thing is that it has been uploaded to IIS. IT has no programming in aspx whatsoever just .html .css and .js

  • JQuery Help: toggle() is not working properly

    Hi All, I'm trying to use JQuery toggle functionality, but not able to use properly. Instead of smooth slide up and down, it goes very fast and not in an animated manner. I want to achieve sliding effect in my code, like this has (Please see Website Design, Redesign Services slider): Here is my code: HTML: <div> <div class="jquery_inner_mid"> <div class="main_heading"> <a href="#"> <img src="features.jpg" alt="" title="" border="0" /></a> </div> <div class="plus_sign"> <img id="imgFeaturesEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgFeaturesCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divMain" > </div> </div> </div> <div class="jquery_inner_mid"> <div class="main_heading"> <img src="About.jpg" alt="" title="" /></div> <div class="plus_sign"> <img id="imgTechnoEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgTechnoCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divTechnossus" > </div> </div> </div> </div> JQuery: $(function() { document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'none'; $('#imgFeaturesEx').click(function() { $.getJSON("/Visitor/GetFeatureInfo", null, function(strInfo) { document.getElementById('divMain').innerHTML = strInfo; }); $("#divMain").toggle("slow"); document.getElementById('imgFeaturesEx').style.display = 'none'; document.getElementById('imgFeaturesCol').style.display = 'block'; }); $('#imgFeaturesCol').click(function() { document.getElementById('divMain').innerHTML = ""; $("#divMain").toggle("slow"); document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgFeaturesEx').style.display = 'block'; }); $('#imgTechnoEx').click(function() { $.getJSON("/Visitor/GetTechnossusInfo", null, function(strInfo) { document.getElementById('divTechnossus').innerHTML = strInfo; }); $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoEx').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'block'; }); $('#imgTechnoCol').click(function() { document.getElementById('divTechnossus').innerHTML = ""; $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoCol').style.display = 'none'; document.getElementById('imgTechnoEx').style.display = 'block'; }); });

  • Roles / Permissions framework for c#?

    Hi there, Does anyone know of a good framework to allow me design permission and roles against users. Basically allowing me to automatically check a user can do a certain thing, and then disabling or enabling menu items etc I am not really looking for asp.net security ... as i need to use it in my own service layer and clients both WEB and WPF will use it. I was hoping for something that allows me to create new roles and groups against users and then check what type of permissions a user has or a group has Any help really appreciated.. I am sure some kind of open source framework is available, well i was hoping not having to create my own Thanks

  • Is it possible to virtualize war file execution without separate J2EE container deployments?

    - by Smith
    Let's say I want to allow my developers to upload their war files to a web app (not the application server itself) running on our intranet and that web app would then run those wars as if they were separate apps deployed individually in our J2EE container. In other words, we are not actually deploying the wars as separate apps in the container - they are simply running side-by-side inside this one web app that acts like a J2EE container. Is that possible? Something like a war virtualization app?

  • web design question (php/ajax)

    - by tom smith
    Hi guys... Hope this isn't a waste of your time. I'm working on a project, and it occured to me that there's a chunk of code out there, that should allow me to see how others have implemented this. I've got a project where I'm going to have a page, with a sel box. the user will select an item from the selList, and based on the item selected, a separate section of the page (areaB) will change in terms of the content/tbls being displayed. i then want to allow the user to go through a series of subpages in areaB, where the user goes through a submit/cancel/confirm process, where the stuff in areaB changes, with the rest of the page remaining the same... i'm trying to figure out the best approach to implement the on both client/server side. i could just have an ugly "if block" where i have abunch of logic, and i completely regen the page each time the user selects an action.. i could have an approach that might involve divs/frames, where i then just regen the targeted frame/div area.. is this even possible?? i could have some form of ajaxy process, which would only alter the targeted section(s) of the page... so.. i'm trying to talk to anyone who has ideas on how to do this, or more ideally, if you know of a good code (client/server) side example of this... that i can examine. i'd really appreciate it!! i've got a more detailed overview but didn't know if it would be cool to post it here... thanks.. tom

  • How do I verify the URL that ActiveResource intends to use on a call?

    - by btelles
    Hi there, I'm trying to request data from another Rails app, but I keep getting a "URL not found" error. Is it possible to use the debugger to figure out the intended URL and parameters for an intended ActiveResource call? For example, I'd like to make a GET request with the following parameters: https://some_server.com/employees/search.xml?last_name=smith And I have the following ActiveResource model class Employee < ActiveResource::Base self.site = "https://.some_server.com" end And the some_server.com app has a search action that maps this way: map.connect "/employees/search.:format", :controller => 'employees', :action => 'search' But when I try this: Employee.new(:last_name => 'smith).get(:search) I get a 404 "Service not found" error. To me, that sounds like the URL that ACtiveResource is requesting is incorrect, 'cause when I make the above request via a browser, I get the xml. Any idea what I'm doing wrong? Cheerio, Berns

  • Bug in XCode debugger?

    I am working on an iPhone app which is using an external library for which I have the source. During debugging some of the objects are listed as 0x0 in the debugger but the app runs fine. Also, some of the objects addresses point to the wrong thing. These symbols are in the external library. The addresses are fine if I am tracing through a file actually in the external library. Does anyone have suggestions how to stop this behavior?
