• Automate publishing of a WCF library using MSBuild

  - by user438334

  I searched and couldn't find anything releated to this topic. When using Visual Studio 2010 for a WCF library, you can right-click it and publish the WCF Library, which generates/creates the .svc and web.config file as well as deploys it. I have been trying to mimic this in msbuild and have had no success. Is this possible? I have build scripts to deploy a WCF application, website, and have had no luck using these scripts to successfully deploy a WCF library. When i do use them, it compiles the Dll's but not the .svc or web.config file. Any advice would be greatly appreciated.

• template static classes across dynamic linked libraries

  - by user322274

  Hello, I have a templated class with a static value, like this: template <class TYPE> class A{ static TYPE value; }; in the code of a dll I assign the static value: code of DLL_1 A<float>::value = 2.0; I wish the value to be shared by all the dlls I'm using, i.e. I want that: code of DLL_2 printf("value on DLL_2 %f",A<float>::value); print out "2.0" any clues? thx

• VS2008 project with Entity Framework model results in "always dirty" compile

  - by Jeremy Lew

  In VS 2008, I have a simple .csproj that contains an Entity Framework .edmx (V1) file. Every time I build the project, the output DLL is updated, even though nothing has changed. I have reproduced this in the simplest-possible project (containing one ordinary .cs file and one edmx model). If I remove the edmx model and build repeatedly, the output assembly will not be touched. If I add the edmx model and build repeatedly, the output assembly is modified each time. This is a problem because the real project is a dependency of dozens of other projects and it is wreaking havoc with what times when working in higher layers of the application. Is this a known problem? Any way to fix it? Thanks!

• C# How to download files from FTP Server

  - by user3696888

  I'm trying to download a file (all kinds of files, exe dll txt etc.). And when I try to run it an error comes up on: using (FileStream ws = new FileStream(destination, FileMode.Create)) This is the error message: Access to the path 'C:\Riot Games\League of Legends\RADS\solutions \lol_game_client_sln\releases\0.0.1.41\deploy'(which is my destination, where I want to save it) is denied. Here is my code void download(string url, string destination) { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(url); request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential("user", "password"); request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { using (Stream rs = response.GetResponseStream()) { using (FileStream ws = new FileStream(destination, FileMode.Create)) { byte[] buffer = new byte[2048]; int bytesRead = rs.Read(buffer, 0, buffer.Length); while (bytesRead > 0) { ws.Write(buffer, 0, bytesRead); bytesRead = rs.Read(buffer, 0, buffer.Length); } } } }

• How do I convert a Python list of lists of lists into a C array by using ctypes?

  - by pc05

  As seen here How do I convert a Python list into a C array by using ctypes? this code will take a python array and transform it to a C array. import ctypes arr = (ctypes.c_int * len(pyarr))(*pyarr) Which would the way of doing the same with a list of lists or a lists of lists of lists? For example, for the following variable list3d = [[[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]]] I have tried the following with no luck: ([[ctypes.c_double * 4] *2]*3)(*list3d) # *** TypeError: 'list' object is not callable (ctypes.c_double * 4 *2 *3)(*list3d) # *** TypeError: expected c_double_Array_4_Array_2 instance, got list Thank you! EDIT: Just to clarify, I am trying to get one object that contains the whole multidimensional array, not a list of objects. This object's reference will be an input to a C DLL that expects a 3D array.

• Can you use Win32 GUI in a browser plugin?

  - by John

  Of course it would mean you're plugin is not cross-platform but let's focus on the technical side... Is a browser plugin (like done in NPAPI) restricted in what it can do? Or do you get fairly free reign to access the PC and the render-window you're given? For instance can you create Win32/MFC controls in your browser this way? A side question - is your browser plugin conceptually akin to a .DLL, which is therefore just arbitrary compiled code implementing a specific interface for browser control/communication?

• How to get information about a Windows executable (.exe) using C++

  - by ereOn

  Hi, I have to create a software that will scan several directories and extracts information about the executables found. I need to do two things: Determine if a given file is an executable (.exe, .dll, and so on) - Checking the extension is probably not good enough. Get the information about this executable (the company name, the product name, and so on). I never did this before and thus am not aware if there is a Windows API (or lightweight C/C++ library) to do that or if it is even possible. I guess it is, because explorer.exe does it. Do you guys know anything that could point me in the right direction ? Thank you very much for your help.

• Delay-Load equivalent in unix based systems

  - by saran

  What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

• How to decode U.P.S. Information from UPS MaxiCode Barcode?

  - by user46482

  I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL. Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data. [)01961163522424800031Z50978063UPSN12312307G:%"6*AH537&M9&QXP2E:)16(E&539R'64O In other words, this text seems OK - and I can parse the information [)01961163522424800031Z50978063UPSN123123 ... While, this data seems to be encrypted ... 07G:%"6*AH537&M9&QXP2E:)16(E&539R'64O Any Ideas???

ReSharper 5 is trying to resolve this view, but can't find it. Which is explainable in my situation. What i want is to disable the option for ReSharper to try and resolve the views. Is this possible?

• In .NET, How to obtain the target of a symbolic link (or Reparse Point)?

  - by Cheeso

  In .NET, I think I can determine if a file is a symbolic link by calling System.IO.File.GetAttributes(), and checking for the ReparsePoint bit. like so: var a = System.IO.File.GetAttributes(fileName); if ((a & FileAttributes.ReparsePoint) != 0) { // it's a symlink } How can I obtain the target of the symbolic link, in this case? ps: I know how to create a symbolic link. It requires P/Invoke: [Interop.DllImport("kernel32.dll", EntryPoint="CreateSymbolicLinkW", CharSet=Interop.CharSet.Unicode)] public static extern int CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, int dwFlags);

• Windows fonts not immediately useable in application after installing?

  - by Jappie

  Whenever I install a new font on a Windows 2003 server, I can't use it immediately in my asp.net web application. The application gets the font through the CreateFontIndirect gdi32.dll win api. It seems like fonts get cached somewhere, because I will just get the default font returned. The font cache gets updated after a reboot, and then I get the correct font, but obviously I wouldn't like to do a reboot on a production server just for getting a new font to work. Is there a way to flush the font cache?

• Howto take a glimpse into mscorlib?

  - by panny

  Hi all! I want to read data into RSAParameters structure ( RSAParameters ) and did check twice, that the data is correct. But still, I get an error "invalid data" exception for this: bei System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException(Int32 hr) bei System.Security.Cryptography.Utils._ImportKey(SafeProvHandle hCSP, Int32 keyNumber, CspProviderFlags flags, Object cspObject, SafeKeyHandle& hKey) bei System.Security.Cryptography.RSACryptoServiceProvider.ImportParameters(RSAParameters parameters) How can I take a look into the source code to check why _ImportKeys is throwing an exception? I have no experience with .dll 'decryption'..are there any symbols to reference somewhere for visual studio 8.0? Thank you.

• Detect if an assembly is available

  - by jgaa

  I'm implementing an installer in Java, that is supposed to download and install an application for non-privileged users in Windows (from XP and up). The application is written in C++, and depend on the usual VC runtime-libraries (msvcm90.dll and friends). In order to save bandwidth, I want to avoid downloading the VC redistributables if they already are available for the user. I do however have a problem finding a reliable method to detect if an assembly is installed. If the assembly is missing, I will deploy it as described here: http://msdn.microsoft.com/en-us/library/ms235291%28VS.80%29.aspx So the question is simply how to detect if a (any) assembly is installed on the machine. It's no requirement that this can be done from Java. I can easily write a small probe in C++ and link it statically for the task. jgaa

• How can I use the fucntion CoGetClassObject in x64

  - by fishbein

  I have COM DLL that compiled in x32(the server side). I registered it and tried to use the function CoGetClassObject with client that works in x32 for getting the IClassFactory. Hr = CoGetClassObject(CLSID_IOrbCom, CLSCTX_INPROC_SERVER, 0 , IDD_IClassFactory, (LPVOID*)&ClassFactory) the result with client x32 was fine and everything works well. But when I tried to use the CoGetClassObject in x64 client I received failed error "Class not registered". P.S. Restriction: - I can only compiled the COM server with x32. - My OS is XP 64bit.

• Upgrade to 4.0 Framework, then downgraded, now can't find Linq namespace?

  - by CubanX

  I just upgraded from VS2008 to VS2010. In the process, I allowed it to upgrade my DLL's to 4.0. I've decided that wasn't a good idea and now I've rolled back. It all works fine in VS2010, but when it hits my CI server (CruiseControl.Net), I get an error of: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference? 3.5 is on the server, and other projects that use 3.5 build fine, so I don't think it's a framework issue. Anyone have any hints?

• How do I build a python string from a raw (binary) ctype buffer?

  - by fcrazy

  I'm playing with Python and ctypes and I can't figure out how to resolve this problem. I call to a C function which fills a raw binary data. My code looks like this: class Client(): def __init__(self): self.__BUFSIZE = 1024*1024 self.__buf = ctypes.create_string_buffer(self.__BUFSIZE) self.client = ctypes.cdll.LoadLibrary(r"I:\bin\client.dll") def do_something(self): len_written = self.client.fill_raw_buffer(self.__buf, self.__BUFSIZE) my_string = repr(self.__buf.value) print my_string The problem is that I'm receiving binary data (with 0x00) and it's truncated when I tried to build my_string. How can I build my_string if self._buf contains null bytes 0x00? Any idea is welcome. Thanks

• How do you make a WiX project build when dependent files have changes?

  - by Scott Langham

  Hi, I've adopted a Visual Studio solution that contains a number WiX projects. We build the solution from an MsBuild script to generate the product's installer msi. The problem I'm experiencing is that if I build (and don't rebuild), even if exe's and dll's get updated that need to be put in the installer, the WiX build system doesn't seem to detect this and skips building the installer as it thinks it's already up to date. How do I work out what the dependencies are that are needed to build a WiX project, and how do I tell the Wix build system to watch out for them changing so it knows to build instead of skip?

• An elegant / simple way to check whether internet is available or not.

  - by Trainee4Life

  I did a quick search on how to check whether Internet is available or not. Most of them talked about making InterOp calls to wininet.dll. One of the answers pointed towards System.Net.NetworkInformation namespace. Exploring the namespace I found a class Ping which could be used to pinging to our servers from code, and checking whether server is available or not. What I want to ask is how this solution compares to other solutions? Ping soPing = new Ping(); var soPingReply = soPing.Send("www.stackoverflow.com"); if (soPingReply.Status != IPStatus.Success) { // SO not available }

• How do game trainers change a address in memory thats dynamic?

  - by GameTrainersWTF

  Lets assume i am a game and i have a global int* that contains my health. A game trainers job is to modify this value to whatever in order to achieve god mode. I've looked up tutorials on game trainers to understand how they work, and the general idea is to use a memory scanner to try and find the address of a certain value. Then modify this address by injecting a dll or whatever. But i made a simple program with a global int* and its address changes every time i run the app, so i don't get how game trainers can hard code these addresses? Or is my example wrong? What am i missing?

• LNK2005: delete already defined error in VC++

  - by user333422

  Hi, I asked this question earlier as well: http://stackoverflow.com/questions/2773168/lnk2005-delete-already-defined-error-in-vc The answer I got was that I should be using dynamic version of DLLs. I did that and it compiled fine. Now, but when I gave the exe to one of my colleagues to run, they told me - they can't run it as it requires some shared dll, so they need a static one. When I try to do static build then I get the error as mentioned in my previous link. Do, I need to provide some other file as well with exe. I have got .lib file as well in the build directory. Shall I provide taht one as well? I can run it fine on my m/c in whichever directory I put it. Any help is much appreciated as I am really stuck. Thanks in advance, Suchita

• Access to bytes array of a Bitmap

  - by Deulis

  1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?
