• Using Visual Studio 2008 to Assemble, Link, Debug, and Execute MASM 6.11 Assembly Code

  - by Kreychek

  I would like to use Visual Studio 2008 to the greatest extent possible while effectively compiling/linking/building/etc code as if all these build processes were being done by the tools provided with MASM 6.11. The exact version of MASM does not matter, so long as it's within the 6.x range, as that is what my college is using to teach 16-bit assembly. I have done some research on the subject and have come to the conclusion that there are several options: Reconfigure VS to call the MASM 6.11 executables with the same flags, etc as MASM 6.11 would natively do. Create intermediary batch file(s) to be called by VS to then invoke the proper commands for MASM's linker, etc. Reconfigure VS's built-in build tools/rules (assembler, linker, etc) to provide an environment identical to the one used by MASM 6.11. Option (2) was brought up when I realized that the options available in VS's "External Tools" interface may be insufficient to correctly invoke MASM's build tools, thus a batch file to interpret VS's strict method of passing arguments might be helpful, as a lot of my learning about how to get this working involved my manually calling ML.exe, LINK.exe, etc from the command prompt. Below are several links that may prove useful in answering my question. Please keep in mind that I have read them all and none are the actual solution. I can only hope my specifying MASM 6.11 doesn't prevent anyone from contributing a perhaps more generalized answer. Similar method used to Option (2), but users on the thread are not contactable: http://www.codeguru.com/forum/archive/index.php/t-284051.html (also, I have my doubts about the necessity of an intermediary batch file) Out of date explanation to my question: http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html Probably the closest thing I've come to a definitive solution, but refers to a suite of tools from something besides MASM, also uses a batch file: http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit I apologize if my terminology for the tools used in each step of the code - exe process is off, but since I'm trying to reproduce the entirety of steps in between completion of writing the code and generating an executable, I don't think it matters much.

• Designer issue in VS: Events cannot be set on the object passed to the event binding service ...

  - by serhio

  I have a little problem: the Winform control (that contains between others WPF) suddenly stopped to be displayed in Designer. Message: Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located.

• Calling AuditQuerySystemPolicy() (advapi32.dll) from C# returns "The parameter is incorrect"

  - by JCCyC

  The sequence is like follows: Open a policy handle with LsaOpenPolicy() (not shown) Call LsaQueryInformationPolicy() to get the number of categories; For each category: Call AuditLookupCategoryGuidFromCategoryId() to turn the enum value into a GUID; Call AuditEnumerateSubCategories() to get a list of the GUIDs of all subcategories; Call AuditQuerySystemPolicy() to get the audit policies for the subcategories. All of these work and return expected, sensible values except the last. Calling AuditQuerySystemPolicy() gets me a "The parameter is incorrect" error. I'm thinking there must be some subtle unmarshaling problem. I'm probably misinterpreting what exactly AuditEnumerateSubCategories() returns, but I'm stumped. You'll see (commented) I tried to dereference the return pointer from AuditEnumerateSubCategories() as a pointer. Doing or not doing that gives the same result.

• Drawing custom graphics on the iPhone: CALayer vs. CGContext

  - by Henry Cooke

  Hi all, I have an application in which I'm doing some custom drawing, a bunch of lines on a gradient background, like so (ignore the text, they're just UILabels): At the moment, that's all done by starting a new CGContext, drawing stuff into it with CGContextDrawLinearGradient and CGContextStrokePath, then finally saving the resulting image with UIGraphicsGetImageFromCurrentImageContext. The positioning info is calculated while I'm laying out those labels, so it'd be a PITA (and duplication of effort) to calculate it all over again when the containing UIView is drawn with drawRect, so I'm drawing it ahead of time into a UIImage. All works fine, so far so good. However, I have a sneaking suspicion that it may be more efficient to use CALayers to do this drawing. My (cursory) understanding of the difference between the two approaches is that a CALayer is more like a bunch of instructions to draw stuff, and so takes up less memory until it's actually drawn onscreen, whereas drawing everything into a UIImage ahead of time means that you've got a sodding great bitmap kicking around in memory all the time, whether it's drawn or not. Is that a correct understanding? What is generally considered to be the best way of drawing custom images on the iPhone?

• WPF Animation FPS vs. CPU usage - Am I expecting too much?

  - by Cory Charlton

  Working on a screen saver for my wife, http://cchearts.codeplex.com/, and while I've been able to improve FPS on lower end machines (switch from Path to StreamGeometry, use DrawingVisual instead of UserControl, etc) the CPU usage still seems very high. Here's some numbers I ran from a few 5 minute sampling periods: ~60FPS 35% average CPU on Core 2 Duo T7500 @ 2.2GHz, 3GB ram, NVIDIA Quadro NVS 140M (128MB), Vista [My dev laptop] ~40FPS 50% average CPU on Pentium D @ 3.4GHz, 1.5GB ram, Standard VGA Graphics Adapter (unknown), 2003 Server [A crappy desktop] I can understand the lower frame rate and higher CPU usage on the crappy desktop but it still seems pretty high and 35% on my dev laptop seems high as well. I'd really like to analyze the application to get more details but I'm having issues there as well so I'm wondering if I'm doing something wrong (never profiled WPF before). WPF Performance Suite: Process Launch Error Unable to attach to process: CCHearts.exe Do you want to kill it? This error message occurs when I click cancel after attempting launch. If I don't click cancel it sits there idle, I guess waiting to attach. Performance Explorer: Could not launch C:\Projects2\CC.Hearts\CC.Hearts\bin\Debug (USEVISUAL)\CCHearts.exe. Previous attempt to profile the application finished unsuccessfully. Please restart the application. Output Window from Performance: Profiling started. Profiling process ID 5360 (CCHearts). Process ID 5360 has exited. Data written to C:\Projects2\CC.Hearts\CCHearts100608.vsp. Profiling finished. PRF0025: No data was collected. Profiling complete. So I'm stuck wanting to improve performance but have no concrete way to determine where the bottleneck is. Have been relatively successful throwing darts at this point but I'm beyond that now :) PS: Screensaver is hosted at CodePlex if you want to look at the source and missed the link above. Edit: My RenderOptions darts... // NOTE: Grasping at straws here ;-) RenderOptions.SetBitmapScalingMode(newHeart, BitmapScalingMode.LowQuality); RenderOptions.SetCachingHint(newHeart, CachingHint.Cache); RenderOptions.SetEdgeMode(newHeart, EdgeMode.Aliased); I threw those a little while back and didn't see much difference (not sure if the bitmap scaling even comes into play). Really wish I could get profiling working to know where I should try to optimize. For now I assume there is some overhead in creating a new HeartVisual and the DrawingVisual contained inside. Maybe if I reset and reused the hearts (tossed them in a queue once they completed or something) I'd see an improvement. Shrug Throwing darts while blindfolder is always fun.

• How to print PCL Directly to the printer? Vb.net VS 2010

  - by Justin

  Good day, I've been trying to upgrade an old Print Program that prints raw pcl directly to the printer. The print program takes a PCL Mask and a PCL Batch Spool File (just pcl with page turn commands, I think) merges them and sends them off to the printer. I'm able to send to the Printer a file stream of PCL but I get mixed results and i do not understand why printing is so difficult under .net. I mean yes there is the PrintDocument class, but to print PCL... Let's just say I'm ready to detach my printer from the network and burn it a live.

• GUI to include a .prop file in a VS 2010 project?

  - by jwfearn

  Visual Studio 2010 has no longer uses .vsprops files and instead uses .props files. To include a .vsprops file in a Visual Studio 2008 project, one could right-click the project icon in the Solution Explorer panel, choose Properties, go to the Configuration Properties | General section, and modify the Inherited Project Property Sheets property to contain a list of .vsprops paths. One could also modify the Visual Studio 2008 project file directly. Is there a way in the Visual Studio 2010 GUI to include .props files to a project? The Inherited Project Property Sheets property seems to have been removed. If manual editing of the project file is the only way to include .props files, where can one find documentation on doing it? I'm not talking about adding a .props file to the list of files in the project, I mean how do I tell the project to use a .props file.

• VS 2010: Can’t insert mvvm-light snippet using shortcut - incompatibility with resharper 5???

  - by mark smith

  Hi there, i recently installed some snippets that come with the mvvm-light framework i am using. And sure enought i checked via Tools > Code Snippet Manager and they are installed under "My Code Snippets". If i do insert Snipper (right click in code window) or CTRL K + CTRL X then i can search within all available snippets.... But i do believe its possible to just type the shortcut key (in this case it is mvvmlocatorproperty) and pressing tab inserts the snippet BUT when i type the shortcut key it is not recognizing anything... What am i doing wrong?? This is not an incompatibility with resharper 5? - which i have installed Any ideas really appreciated

• asp.net mvc, IIS 6 vs IIS7.5, and integrated windows authentication causing javascript errors?

  - by chris

  This is a very strange one. I have an asp.net MVC 1 app. Under IIS6, with no anon access - only integrated windows auth - every thing works fine. I have the following on most of my Foo pages: <% using (Html.BeginForm()) { %> Show All: <%= Html.CheckBox("showAll", new { onClick = "$(this).parent('form:first').submit();" })%> <% } %> Clicking on the checkbox causes a post, the page is reloaded, everything is good. When I look at the access logs, that's what I see, with one oddity - the js library is requested during the page first request, but not for any subsequent page requests. Log looks like: GET / 401 GET / 200 GET /Content/Site.css 304 GET /Scripts/jquery-1.3.2.min.js 401 GET /Scripts/jquery-ui-1.7.2.custom.min.js 401 GET /Scripts/jquery.tablesorter.min.js 401 GET /Scripts/jquery-1.3.2.min.js 304 GET /Scripts/jquery-ui-1.7.2.custom.min.js 304 GET /Scripts/jquery.tablesorter.min.js 304 GET /Content/Images/logo.jpg 401 GET /Content/Images/logo.jpg 304 GET /Foo 401 GET /Foo 200 POST /Foo/Delete 302 GET /Foo/List 200 POST /Foo/List 200 This corresponds to home page, click on "Foo", delete a record, click a checkbox (which causes the 2nd POST). Under IIS7.5, it sometimes fails - the click on the check box doesn't cause a postback, but there are no obvious reasons why. I've noticed under IIS7.5 that every single page request re-issues the requests for the js libraries - the first one a 401, followed by either a 200 (OK) or 304 (not modified), as opposed to the above log extract where that only happened during the 1st request. Is there any way to eliminate the 401 requests? Could a timing issue have something to do with the click being ignored? Would increasing the number of concurrent connections help? Any other ideas? I'm at a bit of a loss to explain this.

• XML/XSD intellisense not working in Visual Studio 2010

  I am working on xml and xsd files in VS 2010 but intellisense isn't working. Intellisense is working for the same files in VS 2008, however. When I type '<xs:' options like "attribute", "complexType", "simpleType", or "element" do not appear. Is there some difference between the VS 2008 and VS 2010 that I'm missing? I add an xsd file to my solution.

• How to utilize WebDev.WebServer.exe (VS Web Server) in x64?

  - by Nick Craver

  Visual Studio is x86 until at least the 2010 release comes around, my question is can anyone think of a way or know of an independent ASP.NET debug server that's x64 for 2008? Background: Our ASP.NET application runs against Oracle as the DB. Since we're on 64-bit servers for memory concerns later, we need to use Oracle's 64-bit drivers (Instant Client). Setup: x64 OS (XP or Windows 7) IIS (5 or 7, both x64 App Pools) Oracle 64-bit Instant Client (Separate Directory, in the PATH) Visual Studio 2008 SP1 In IIS the application pool runs as 64-bit, uses the Oracle drivers as intended, however since WebDev.WebServer.exe is 32-bit you'll get a BadImageFormatException because it's trying to load 64-bit driver DLLs in a 32-bit environment. All of our developers would like to be able to use the quick debug server via Visual Studio 2008, but since it runs as 32-bit we're unable to. Some problems we run into are during application startup, so although we're attaching to the IIS process sometimes that isn't enough to track an issue down. Are there any alternatives, or work-arounds? We would like to match our Dev/Val/Prod tiers as much as possible, so everything running in x64 would be ideal.

  Consider me rusty on the subject of asynchronous delegates. If I want to call a method asynchronously, in a fire-and-forget style, is this an appropriate way to do it? Action action = DoSomething; action.BeginInvoke(action.EndInvoke, null); The DoSomething() method catches all exceptions and deals with them internally. Is the call to EndInvoke appropriate? Required? Is there a clearer way to achieve the same behaviour?

  When setting the ModelView matrix you normally go through several transformations from the identity matrix. for example: glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glRotatef(270.0f, 0.0f, 0.0f, 1.0f); glTranslatef(-rect.size.height / 2, -rect.size.width / 2, 0.0f); Instead of doing those operations one after the other (assume there are more than two), wouldn't it be more efficient to simply pre-calculate the resulting matrix and set the ModelView matrix to this manual matrix?

• Entity Framework vs. nHibernate for Performance, Learning Curve overall features

  - by hadi

  I know this has been asked several times and I have read all the posts as well but they all are very old. And considering there have been advancements in versions and releases, I am hoping there might be fresh views. We are building a new application on ASP.NET MVC and need to finalize on an ORM tool. We have never used ORM before and have pretty much boiled down to two - nHibernate & Entity Framework. I really need some advice from someone who has used both these tools and can recommend based on experience. There are three points that I am focusing on to finalize - Performance Learning Curve Overall Capability Your advice will be highly appreciated. Best Regards,

• Map NHibernate entity to multiple tables based on parent

  - by Programming Hero

  I'm creating a domain model where entities often (but not always) have a member of type ActionLog. ActionLog is a simple class which allows for an audit trail of actions being performed on an instance. Each action is recorded as an ActionLogEntry instance. ActionLog is implemented (approximately) as follows: public class ActionLog { public IEnumerable<ActionLogEntry> Entries { get { return EntriesCollection; } } protected ICollection<ActionLogEntry> EntriesCollection { get; set; } public void AddAction(string action) { // Append to entries collection. } } What I would like is to re-use this class amongst my entities and have the entries map to different tables based on which class they are logged against. For example: public class Customer { public ActionLog Actions { get; protected set; } } public class Order { public ActionLog Actions { get; protected set; } } This design is suitable for me in the application, however I can't see a clear way to map this scenario to a database with NHibernate. I typically use Fluent NHibernate for my configuration, but I'm happy to accept answers in more general HBM xml.

• Entity Attribute Value Database vs. strict Relational Model Ecommerce question

  - by Dr. Zim

  It is safe to say that the EAV/CR database model is bad. That said, Question: What database model, technique, or pattern should be used to deal with "classes" of attributes describing e-commerce products which can be changed at run time? In a good E-commerce database, you will store classes of options (like TV resolution then have a resolution for each TV, but the next product may not be a TV and not have "TV resolution"). How do you store them, search efficiently, and allow your users to setup product types with variable fields describing their products? If the search engine finds that customers typically search for TVs based on console depth, you could add console depth to your fields, then add a single depth for each tv product type at run time. There is a nice common feature among good e-commerce apps where they show a set of products, then have "drill down" side menus where you can see "TV Resolution" as a header, and the top five most common TV Resolutions for the found set. You click one and it only shows TVs of that resolution, allowing you to further drill down by selecting other categories on the side menu. These options would be the dynamic product attributes added at run time. Further discussion: So long story short, are there any links out on the Internet or model descriptions that could "academically" fix the following setup? I thank Noel Kennedy for suggesting a category table, but the need may be greater than that. I describe it a different way below, trying to highlight the significance. I may need a viewpoint correction to solve the problem, or I may need to go deeper in to the EAV/CR. Love the positive response to the EAV/CR model. My fellow developers all say what Jeffrey Kemp touched on below: "new entities must be modeled and designed by a professional" (taken out of context, read his response below). The problem is: entities add and remove attributes weekly (search keywords dictate future attributes) new entities arrive weekly (products are assembled from parts) old entities go away weekly (archived, less popular, seasonal) The customer wants to add attributes to the products for two reasons: department / keyword search / comparison chart between like products consumer product configuration before checkout The attributes must have significance, not just a keyword search. If they want to compare all cakes that have a "whipped cream frosting", they can click cakes, click birthday theme, click whipped cream frosting, then check all cakes that are interesting knowing they all have whipped cream frosting. This is not specific to cakes, just an example.
