  • How do I debug a DLL from VS2008?

    - by GregH
    I have a program written in VB.Net (Visual Studio 2008) that uses a DLL written in Visual C++ by another developer. I'd like to be able to step in to the C++ code as my code makes calls to methods in the DLL. Since the DLL is it's own solution, I don't think it can be included in my solution/project. I tried putting the DLLs pdb file in the debug/bin directory with the rest of my build and pdb files. However, when I get to the point in stepping through my code, and it gets to the dll call, it just steps right over the dll code. Do I have to manually load symbols? Not sure what I'm doing wrong. Thanks.

  • Multi-threading mechanisms to run some lengthy operations from winforms code and communication with

    - by tmarouda
    What do I want to achieve: I want to perform some time consuming operations from my MDI winforms application (C# - .NET). An MDI child form may create the thread with the operation, which may take long time (from 0.1 seconds, to even half hour) to complete. In the meantime I want the UI to respond to user actions, including manipulation of data in some other MDI child form. When the operation completes, the thread should notify the MDI child that the calculations are done, so that the MDI child can perform the post-processing. How can I achieve this: Should I use explicit threading (i.e., create explicit threads), thread pools? Or simply just propose your solution. Should I create foreground or background threads? And how does the thread communicates with the GUI, according the solution you propose? If you know of a working example that handles a similar situation, please make a note.

  • Controllling Drupal's active/active-trail with duplicate menu items

    - by Mark
    I'm developing a site that requires some duplication of links within the menu: Section A -- Introduction -- Testimonials Section B -- Introduction -- Testimonials Testimonials -- Section A -- Section B So 'Section A Testimonials' and 'Testimonials Section A' point to the same node. But regardless of which menu link people use, I want the person to be in Section A. The problem is that D6 doesn't like duplicate menu items, and it assigns the active and active-trail classes rather unpredictably. So my thought was to create a placeholder node for each item in the Testimonials menu, and then set the URL to something like "testimonials/redirect/section-a", and then use mod_rewrite to redirect over to "section-a/testimonials". With this solution, I will have no duplicate paths in the menu. I'm just hoping this doesn't somehow hurt my SEO. Does anyone know a better solution?

  • HTML table headers always visible at top of window when viewing a large table

    - by Craig McQueen
    I would like to be able to "tweak" an HTML table's presentation to add a single feature: when scrolling down through the page so that the table is on the screen but the header rows are off-screen, I would like the headers to remain visible at the top of the viewing area. This would be conceptually like the "freeze panes" feature in Excel. However, an HTML page might contain several tables in it and I only would want it to happen for the table that is currently in-view, only while it is in-view. Note: I've seen one solution where the table data area is made scrollable while the headers do not scroll. That's not the solution I'm looking for.

  • Can you do icon overlays using Java on Windows OS

    - by Saviz
    I would like to manupilate badges or icon overlays using Java on windows. Basically some files on the drive to have overlays depending what state those files are in. This should be visible through windows explorer. Something simillar to how DropBox does things. Is that possible? I've seen several articles on this topic but none of them use Java. They all seem to use C++ or C# or COM objects. I was looking for a Java solution for windows. Of course I'd like to have a Java solution on Mac's too. Not sure if this is possible but before I give up I thought I ask.

  • Will OpenGL give me any FPS improvement over CoreAnimation for scrolling a large image?

    - by Ben Roberts
    Hi, I'm considering re-writing the menu system of my iPhone app to use Open GL just to improve the smoothness of scrolling a big image (480x1900px) across the screen. I'm looking at doing this as a way to improve on using the method/solution as described here (http://stackoverflow.com/questions/1443140/smoother-uiview). This solution was a big improvement over the previous implementation but it's still not perfect and as this is the first thing the user will see I'd like it to be as flawless as possible. Will switching to OpenGL give me the sort of smooth scrolling I'm looking for? I've stayed clear of OpenGL until now as this is my first app and core animation has handled everything else I've thrown at it well enough, would be good to know if this alternative implementation is likely to work! thanks

  • Multiple client projects to one server project w/ Silverlight & RIA Services Beta

    - by Dale Halliwell
    The type or namespace name 'Resources' does not exist in the namespace 'MyWebProject.Web' (are you missing an assembly reference?) C:\Users\...\MySecondProject\Generated_Code\MyWebProject.Web.g.cs I am having some problems trying to add a second SL client project to my (Ria services) SL Business Application. It has to do with the way the shared Resources files on the Web project are linked to from my new SL client project (the SL client project that was generated by the Business App template works fine). The same problem was brought up in the SL forums but copying the Web folder from my existing SL client doesn't seem to work. How can I add a second SL client project using RIA services to the solution of an existing SL Business Application without these problems over shared resources? Should I avoid the Business Application solution template for solutions with multiple SL clients since it seems to presume only a single client app will be sharing the resource files?

  • XML to be validated against multiple xsd schemas

    - by Michael Rusch
    I'm writing the xsd and the code to validate, so I have great control here. I would like to have an upload facility that adds stuff to my application based on an xml file. One part of the xml file should be validated against different schemas based on one of the values in the other part of it. Here's an example to illustrate: <foo> <name>Harold</name> <bar>Alpha</bar> <baz>Mercury</baz> <!-- ... more general info that applies to all foos ... --> <bar-config> <!-- the content here is specific to the bar named "Alpha" --> </bar-config> <baz-config> <!-- the content here is specific to the baz named "Mercury" --> </baz> </foo> In this case, there is some controlled vocabulary for the content of <bar>, and I can handle that part just fine. Then, based on the bar value, the appropriate xml schema should be used to validate the content of bar-config. Similarly for baz and baz-config. The code doing the parsing/validation is written in Java. Not sure how language-dependent the solution will be. Ideally, the solution would permit the xml author to declare the appropriate schema locations and what-not so that s/he could get the xml validated on the fly in a sufficiently smart editor. Also, the possible values for <bar> and <baz> are orthogonal, so I don't want to do this by extension for every possible bar/baz combo. What I mean is, if there are 24 possible bar values/schemas and 8 possible baz values/schemas, I want to be able to write 1 + 24 + 8 = 33 total schemas, instead of 1 * 24 * 8 = 192 total schemas. Also, I'd prefer to NOT break out the bar-config and baz-config into separate xml files if possible. I realize that might make all the problems much easier, as each xml file would have a single schema, but I'm trying to see if there is a good single-xml-file solution.

  • Problem building with MSBuild on Team Build

    - by mrwayne
    Hi, I have recently upgraded from TFS2005 to TFS2010 (and sub-sequently the team build server). I used to be able to get a team build on one of my solutions to work pretty easily, (see structure below) Solution |_Web Site | |_Bin | |_Other Files |_Project 1 |_Project 2 |_Project (n) Now, i can no longer get a build working correctly as it doesnt appear to build all my projects any longer (i've had to create a new build definition). Either that, or its not building the projects in such an order that when it hits project X, that a project it depends on (Project A), has not yet been built, and as such fails. I'm just basically trying to build a web site (not web application project), with some Dependant / linked projects. Why must it be so hard! Everything builds fine in the IDE. If i even open the solution copied to the build server under the 'Sources' directory, i am able to build it fine in the IDE on that server. No such luck with MSBuild though. Thoughts?

  • Perl: Event-driven Programming

    - by Shiftbit
    Is there any POSIX signals that I could utilize in my perl program to create event-driven programming? Currently I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@threads) { sysread(${$_}{'read'}, my $line, 100); chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution.

  • Hudson leaving open sessions

    - by James Carr
    Does anyone have any experiences with Hudson leaving sessions open to a Subversion server? We've been increasing our job list and got ~50 which poll the SCM regularly. It's been working fine but recently our SCM has started acting up by refusing handshakes, which we suspect is down to the sessions left open by Hudson. Last count there were ~400 sessions with nothing building on Hudson. At the moment the only solution we've found is restarting the Subversion service but this is becoming increasingly frequent and not a long term solution. Any experiences/ideas would be appreciated.

  • Python "Every Other Element" Idiom

    - by Matt Luongo
    Hey guys, I feel like I spend a lot of time writing code in Python, but not enough time creating Pythonic code. Recently I ran into a funny little problem that I thought might have an easy, idiomatic solution. Paraphrasing the original, I needed to collect every sequential pair in a list. For example, given the list [1,2,3,4,5,6], I wanted to compute [(1,2),(3,4),(5,6)]. I came up with a quick solution at the time that looked like translated Java. Revisiting the question, the best I could do was l = [1,2,3,4,5,6] [(l[2*x],l[2*x+1]) for x in range(len(l)/2)] which has the side effect of tossing out the last number in the case that the length isn't even. Is there a more idiomatic approach that I'm missing, or is this the best I'm going to get?

  • converting JSON to an object / dictionary / dynamic

    - by benpage
    I'm currently using jqGrid to display data. Part of jqGrid's interface will give you search options, posting back the search details in a JSON string, for example: {"groupOp":"AND","rules":[{"field":"PersonID","op":"eq","data":"123"},{"field":"LastName","op":"eq","data":"Smith"}]} (meaning i'm searching for personID = 123, and LastName = 'Smith') so what i'm hoping to do is somehow convert that back into something i can use server-side. Does anyone have a solution for this that may convert it back into an object of some kind? My current solution would be to convert into xml, parse with linq and create instances of my own 'search' class with a 'rules' collection.

  • Copy task in Visual Studio 2008

    - by Maurizio Reginelli
    This is a question related to a previous question I posted (see here). I need to configure a .csproj file to copy some files from a directory to another one (let me call them SOURCE and DESTINATION). I also need to change the SOURCE path depending from the configuration I'm using. For example, if I compile my project in Debug mode, the SOURCE path must contain a subfolder called Debug. I tried the solution proposed by Schmitt in the previous post, using $(ConfigurationName) to set the dynamic directory into the SOURCE path. When I opened the solution containing that project, a list of links to the source files appeared in the main tree of the project and they were correctly related to the Debug mode. But when I changed to the Release mode, I saw that the path of the linked source files were set again to the Debug version. Is there a way to specify a parameter in the Include attribute of the SourceFiles element? Thank you.

  • “Could not create the file”, “Access is denied” and “Unrecoverable build error” in building setup project in VS 2008

    - by Mister Cook
    When building a setup project I get a message: Error with setup build: Error 27 Could not create the file 'C:\Users\MyName\AppData\Local\Temp\VSI1E1A.tmp' 'Access is denied.' I have tried the following (from http://support.microsoft.com/kb/329214/EN-US) regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\MSI Tools\mergemod.dll" The DLL registers but this does not fix my problem. Also, I tried a Clean build, deleting the temp folder, ran VS2008 as administratror, restart my PC but it occurs every time. I have no anti-virus software running and running on Windows 7 64-bit. This operation worked fine until recently. I have read many other users see this but found no solution. The only half solution I found was to edit setup properties and switch to Package files as Loose uncompressed files. This works but is not ideal as I need a full installer.

  • Diophantine Equation

    - by swapnika
    Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n" Hints: Hypothesize possible instances of numbers of McNuggets that cannot be purchased exactly, starting with 1 For each possible instance, called n, 1. Test if there exists non-negative integers a, b, and c, such that 6a+9b+20c = n. (This can be done by looking at all feasible combinations of a, b, and c) 2. If not, n cannot be bought in exact quantity, save n When you have found six consecutive values of n that in fact pass the test of having an exact solution, the last answer that was saved (not the last value of n that had a solution) is the correct answer, since you know by the theorem that any amount larger can also be bought in exact quantity

  • Print "1 followed by googolplex number of zeros" [closed]

    - by Rajan
    Assuming we are not concerned about running time of the program (which is practically infinite for human mortals), we want to print out in base 10, the exact value of 10^(googolplex), one digit at a time (mostly zeros). Describe an algorithm (which can be coded on current day computers), or write a program to do this. Since we cannot practically check the output, so we will rely on collective opinion on the correctness of the program. NOTE : I do not know the solution, or whether a solution exists or not. The problem is my own invention. To those readers who think this is not a CS question... kindly reconsider. This is difficult and bit theoretical but definitely CS.

  • MagicLibrary.dll 32bit convert for 64bit

    - by Nullstr1ng
    Hi Guys, I recently received an email about a guy who like to make my software compatible with 64Bit Windows 7 OS. I have 1 single problem though .. I have followed a steps regarding on compiling VS Solution/Project for 64bit. But when I start to to compile the solution for 64bit, this "Crownwood.Magic.Forms" (MagicLibrary.dll) doesn't work anymore. This is the compilation error message "Error 6 The type or namespace name 'Crownwood' could not be found (are you missing a using directive or an assembly reference?)" Please don't tell me I did not referenced the MagicLibrary.dll It's a bit of confusing because the MagicLibrary.dll is already in my reference list. I also remove and add it back. There was this CorFlags.exe but am not sure how to convert it to 64bit. "CorFlags MagicLibrary.dll /32BIT- /Force" did not work.. :( Please help. Thanks in advance - Jayson

  • Sparse O(1) array with indices being consecutive products

    - by Kos
    Hello, I'd like to pre-calculate an array of values of some unary function f. I know that I'll only need the values for f(x) where x is of the form of a*b, where both a and b are integers in range 0..N. The obvious time-optimized choice is just to make an array of size N*N and just pre-calculate just the elements which I'm going to read later. For f(a*b), I'd just check and set tab[a*b]. This is the fastest method possible - however, this is going to take a lot of space as there are lots of indices in this array (starting with N+1) which will never by touched. Another solution is to make a simple tree map... but this slows down the lookup itself very heavily by introducing lots of branches. No. I wonder - is there any solution to make such an array less sparse and smaller, but still quick branchless O(1) in lookup?

  • is magento overkill for a one-man webshop?

    - by Rick J
    I have been looking at magento for a while and I think I have a decent handle on how to use/customize it. I have a client that wants a webshop , this is just a small business that sells a few products and just supports one language. I was wondering if using magento will be an overkill for a simple webshop , in case I cant help them to make future changes tp the webshop, the people running their business might have to do it. But it looks like magento is made for people with some technical know how (lots of xml editing etc).. So should i go for magento or a simpler solution like osCommerce or maybe even a simple custom solution. Would like to hear your opinions!

  • Java simple encryption

    - by Ran
    Hello, I would like to encrypt a textual (configuration) file stored on disk. Trying to use DES encryption I've had fatal error on client machines, I later found out caused because the algorithm could not handle accented characters (!) I suspect that was because I was using old packages (sun.misc.BASE64Decoder) - but I'm not sure that is the reason. However, I'm looking for a simpler solution - I need a really simple encryption (I know some people would not agree on that) - not RSA of 128 bit keys or so, just obscuring the text from curious eyes. It is really weird that I could not find on the web a simple trivial solution. Any idea, anyone ? Thanks, Ran

  • Team build of Web Projects generates App_web_xxxx.dll files and TFSBuild.Proj Script

    - by Steve Johnson
    Hi all, I have a web application that has some non-web projects as well. When using Web Deployment, a single assembly is generated for all the aspx.vb files. When using Team Build (TS 2008), a lot number App_Web_xxx.dll file(s) are generated instead of a single assembly. How can i solve this problem and change the TFSBuild.proj file so that it can generate a single Web Assembly instead of a lot number of assemblies. Please help. Thanks Edit: I guess thats because the MERGE operation is not occurring like it used to happen for Web Deployment Project in my solution. How can i enable MERGE of App_web_*.dll files into a single Web.dll assembly file and delete the satellite assemblies? Here is my code from TFSBuild.proj file: (MY web project is in Release|.NET Config and all other projects within the solution are in Release|Any CPU) true .\Debug true true Web true false .\Release true true Web true Please tell me what are the corrections i need to do.,
