  • How do I use functions from a DLL?

    - by Russel
    How do I use functions from a DLL? I'm a total newbie and I don't really understand how to use functions from a DLL file. I'm trying to use MS Visual Studio 2008 (C++). My understanding is that the DLL files will have corresponding header files and as long as I include the header files and call the functions normally in my code, it should work? Is that correct? Then I would just need to have the compiled exe file be able to find the DLL? Please let me know if that is a remotely correct understanding! Thanks! Russel

  • Best means to store data locally when offline

    - by mickartz
    I am in the midst of writing a small program (more to experiment with vs 2010 than anything else) Despite being an experiment it has some practical use for our local athletics club. My thought was to access the DB (currently online) to download the current members and store locally on a laptop (this is a MS sql table, used to power the club's website). take the laptop to the event (yes there ARE places that don't have internet coverage), add members to that days race (also a row from a sql table (though no changes would be made to this), record results (new records in 3rd table) Once home, showered and within internet access again, upload/edit the tables as per the race results/member changes etc. So I was thinking i'd do something like write xml files locally with the data, including a field to indicate changes etc? If anyone can point me in a direction i would appreciate it...hell if anyone could tell me if this has a name, I'd appreciate it.

  • Help with concept - filters and number of items

    - by dreamer
    Please check http://www.alibaba.com/catalogs/cid/702/Laptops.html they have nice filter here with number of items for each. Note one detail - they have locations here. Same thing on olx.com - location and number of items for each category. Now imagine I have tables: [products] (Id, Name, CategoryId, LocationId) [Categories] (Id,Name) [Location] (Id, Name) My question how can I do the same, cause count things even with caching looks expensive? And they give results pretty fast... Please advice with possible ways to do that in ASP.NET, C#, MVC, MS SQL, but avoice simple answers like "count and change" Thank you in advance.

  • SQL Compact Edition database corruption

    - by jdv
    Hi, Our product is using MS SQL Compact Edition on a Windows machine (laptop). It's basically a metadata index for files we have on the filesystem. Recently we have seen databases getting corrupted. This happens when the machine is very busy moving files around and has to do a tiny bit of database changes at the same time. I was somewhat shocked that was at all possible. It was my expectation that the database would stay coherent whatever the circumstances. Of course we are doing something wrong. Things we have checked so far are: Use of only one db connection per thread specify the maximum size when opening the database The database is accessed only by one application, a .net based windows service. Are there other gotcha's?

  • Can i configure emacs to use gdb like a graphical debugger?

    - by Joey Carson
    I'm pretty sure that this how other IDE's do it, e.g. on windows eclipse uses the output of gdb from MinGW (the windows port of GNU toolchain) to map where execution is in the source code and what values variables hold, etc. I'm stuck using gdb via a script that prepares our application in a chroot and does some other bootstrap for debug purposes. Once the script starts moving, the output is all gdb. Is there any way that I can configure emacs so that it will use gdb's output and allow for a sort of graphical debugger, comparable to that of eclipse or ms visual studio?

  • How to save the world from your computer?

    - by Francisco Garcia
    Sometimes I miss the "help other people" factor within computer related careers. Sure that out there I could find many great projects improving society, but that is not common. However there are little things that we all can do to make this a better place beyond trying to erradicate annoynig stuff such as Visual Basic. You could join a cloud computing network such as World Community Grid to fight cancer. Write a charityware application such as Vim, improve an office IT infrastructure to support telecommuting and reduce CO2 emissions, use an ebook reader for saving paper... what else would you? which projects do you think can have an impact?

  • Book resources for x86/x64 assembly programming on Win platform

    - by Scott Davies
    Hello, I ran a search for assembly language resources on stackoverflow.com and found some interesting results, but they seemed to boil down to two groups: 1) Assembly references to old ia32 architecture, such as the 80386 to Pentium 2) Windows agnostic books. Most of the commenters make the point that assembler is CPU dependent and that the OS is irrelevant, but it seems pointless to me to pick a book that has assembly examples that refer to MS-DOS interrupts and memory layouts. Likewise, learning assembler on Linux would seem to produce Linux executables Are there any: 1) Modern 2) x86/x64 3) on Windows platform - book resources available ? The reason I am targeting the Win platform is I would like to do low-level, OS internals programming, to supplement my Win C/C++ work. Thanks

  • INSERT SELECT Statement and Rollback SQL

    - by Juan Perez
    Im Working on a creation of a query who uses INSERT SELECT statement using MS SQL Server 2008: INSERT INTO TABLE1 (col1, col2) SELECT col1, col2 FROM TABLE2 Right now the excecution of this query is inside a transaction: Pseudocode: try { begin transaction; query; commit; } catch { rollback; } If TABLE2 has around 40m of rows, at the moment of making the insert on the TABLE1, if there is an error in the middle of the INSERT, will the INSERT SELECT statement make a rollback itself or I need to use a transaction to preserve data integrity? It is necessary to use a transaction? or SQL SERVER it self uses a transaction for this type of sentences.

  • Option Value Changed - ODBC Error 2169

  • Is there a good collection library for C-language?

    - by matti
    We have to maintain and even develop C-code of our legacy system. Is there good collection library that would support Java/C# (new versions) style collections. Hashtable, HashSet, etc. Of course without objects, but with structs. The HashTable key limitations to "strings" and ints is not a problem. It wouldn't be bad if it's free even for commercial use. I'm back to C from C# and I must say i'm depressed using our own libraries and the language in general. We're using VS2005 and MS C-compiler if that has nothing to do with anything. Thanks & BR -Matti

  • Format table header

    - by Ryan Erb
    I have a table with slanted text in the header row, the only problem is that the text still makes the width of the columns way to large. Is there any way to squish together the table columns so that they are about the width of the select boxes? Or is there a way to place the text there without it in the header and maybe just use a <div> or <p>? Here is the fiddle I am working with: http://jsfiddle.net/t9Krg/1/ .slanted { -webkit-transform: rotate(-45deg); -moz-transform: rotate(-45deg); -ms-transform: rotate(-45deg); -o-transform: rotate(-45deg); transform: rotate(-45deg); white-space:nowrap; /* display:noblock; */ } The boarders around the header is just to see the extra spacing and will be removed later.

  • Translate GPS coordinates to location on PDF Map

    - by christo16
    Hi everyone, I'd like to know (from a high level view) what would be required to take a pdf floor plan of a building and determine where exactly you are on that floor plan using GPS coordinates? In addition to location, the user would be presented with a "turn by turn" directions to another point on the map, navigating down hallways, between cubicles, etc. Use case: an iPhone app that determined a user's location and guided them to a conference room or person's office in the building. I realize that this is by no means trivial, but any help is appreciated. Thanks!

  • C++ serial port send command

    - by Ilyssis
    Hi there, I have a hardware here, wich communicates over serial port. I use MS Visual C++ 2010, and I want to send a command: <-S-> I am doing this: SerialPort^ serialPort = gcnew SerialPort(portName , 9600, Parity::None, 8, StopBits::One); serialPort->Open(); serialPort->WriteLine("<-S->"); serialPort->Close(); But the command that goes out is <-S->., and not <-S-> (please notice the point that is attached to the outgoing command). I use Free Serial Port Monitor to watch my ingoing/outcoming data. So how can I get rid of that point in <-S->. ? This is what is going out: 3C 2D 53 2D 3E 0A = <-S-. This is what I want: 3C 2D 53 2D 3E = <-S- Thanks for help.

  • Launch x64 Windows application in C# while the project is set to x86

    - by daydr3am3r
    Hi all I'm trying to launch the osk.exe and I keep getting "Could not start osk" message. The problem is that my project is set to x86 (i'm using a ms access database). If I switch to x64 or Any CPU everything works fine but the database will no longer work. I tried this using System.Diagnostics; private void btnOSK_Click(object sender, EventArgs e) { Process.Start("osk.exe"); Process.Start(@"C:\windows\system32\osk.exe"); } I also tried to run SysWOWW\osk but this also didn't work. Besides my application should run on both x86 and x64 machines. Is there any way to bypass this? It's really frustrating.

  • Google apps API problem with read-only feed?

    - by brandonprry
    Hi all, I am beginning to use the google data api (specifically for the finance app). I can read my portfolio's just fine, so I am authenticating correctly (or so I think). However, when i try and create a portfolio, I get a 'feed is read-only' error. The constructor for the service: public class FinanceService : Service, IService { public FinanceService(string applicationName) : base ("finance", applicationName) { this.RequestFactory = new GDataGAuthRequestFactory("finance", applicationName) { ProtocolMajor = 3 }; } } and saving it is private const string _schema = "http://schemas.google.com/finance/2007"; private const string _feed = "http://finance.google.com/finance/feeds/default/portfolios"; AtomFeed atomFeed = new AtomFeed(new Uri(_feed), this.FinanceService); return this.FinanceService.Insert(atomFeed, this as AtomEntry) as PortfolioEntry; Any idea why the atomFeed would come back ReadOnly? The credentials are legit, and I can get my current portfolios without a problem.

  • Copy Merge fIelds From one word document to another in VB.net

    - by MetaDan
    Hi, I'm editing a vb.net app for a mate and part of the requirements are to copy merge fields from one word document to another. I can copy them across using document.content.text but they come out as text (should've figured this i guess). I think i've got them selected by: Dim tDocFields As Microsoft.Office.Interop.Word.Fields tDocFields = tDocument.Content.Fields I'm then activating the doc i want to copy into and i think i need to then copy into that doc using the related word app. vDocument.Activate() vWord.Selection. ??? Insert() ??? Any pointers would be greatly appreciated... Am i on the right lines even?

  • C++: How would I get unix time?

    - by John D.
    I need a function or way to get the UNIX epoch in seconds, much like how I can in PHP using the time function. I can't find any method except the time() in ctime which seems to only output a formatted date, or the clock() function which has seconds but seems to always be a multiple of 1 million, nothing with any resolution. I wish to measure execution time in a program, I just wanted to calculate the diff between start and end; how would a C++ programmer do this? EDIT: time() and difftime only allow resolution by seconds, not ms or anything too btw.

  • Registered Symbol Problem with Flash Mailto Link

    The problem I'm having is an extra  Chracter being added before the ® symbol in the body of an email created from a mailto: link in flash. This only happens on the PC in MS Outlook Instead of: MasterCard®! It shows up as MasterCard®! The code in flash AS3: var req = new URLRequest("mailto:"); var variables = new URLVariables(); variables.body="Blah Blah Blah MasterCard®!"; variables.subject="Make some music!"; req.data = variables; req.method = URLRequestMethod.GET; addEventListener(MouseEvent.CLICK, onClick); function onClick(e:MouseEvent) { navigateToURL(req, "_self"); } } This works fine on the mac with mac mail.

  • Can I safely move my project to .NET 4.0?

    - by Decker
    I've migrated my project to VS2010 but have not yet targeted .NET 4.0. It's currently targeting 3.5 SP1 (and CLR 2). The project relies on several third party components -- mostly open source -- that were presumably built against the 2.0 CLR. Can I simply retarget my project to the 4.0 runtime? Or do I have to get new versions of all the referenced assemblies on which it depends? I've read a little about the new in-process side-by-side feature of .NET 4.0, but I don't think it applies here (the example I read was about two different .NET plug ins to an office application). My situation is different. My solution directly references assemblies and I wouldn't think side-by-side applies -- unless I don't understand its purpose. TIA

  • MultiOS "Jet Database" for QtC++?

    - by Airjoe
    Hopefully I can articulate this well: I'm porting an application I made years ago from VB6 (I know, I know!) to QtC++. In my original application, one thing I liked was that I didn't need an actual SQL server running, I could just use MS Access .mdb files. I was wondering if something similar exists for QtC++ that will work on multiple OSes- a database stored in a file, pretty much, but that I can still run SQL queries with. Not sure if something like this exists or not, but any help appreciated, thanks!

  • Running sites on "localhost" is extremeley slow.

    - by seanxe
    Hello all, Having real trouble using my local host to test sites. It runs extremely slow! Sometimes up to a minute to load a page. I'm using firefox and the sites i'm testing run fine on other developers in my office local machines/ on the production server. I've gone through the normal things :- Disabled IPv6 Not running in debug mood Put the site in the highest app pool (High Isolated) on IIS 6. Taking of firewalls etc. The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind. Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it's horrible waiting a minute each refresh to try out a change! Cheers, Sean.

  • ODBC Storage Size

    - by dcp3450
    I'm pulling a lot of text from a MS SQL Server database. I'm not getting all the text (which includes some html. The text is stored perfectly on the database. However, when I run the query to get the data It will only pull part of the text. I pull the data using odbc_exec and store using $variable = odbc_result($runquery,"body"). if i display the content with odbc_result_all($runquery) i get part of the content. if I use echo $body; i get part of the content then some garbage and part of the text from the begining. very strange response. Is there a size limit? Any ideas what I'm missing here?

  • Options for header in raw byte file.

    - by Tim
    I have a large raw data file (up to 1GB) which contains raw samples from a USB data logger. I need to store extra information relating to the file (sample rate, description, trigger point, last seek position etc) and was looking into adding this as a some sort of header. The header file should ideally be human readable and flexible so I've so far ruled out some sort of binary serialization into a header. I also want to avoid two separate files as they could end up separated when copied or backed up. I remembered somebody telling me that newer *.*x Microsoft Office documents are actually a number of files in a zip. Is there a simple way to achieve this? Could I still keep the quick seek times to the raw file?
