问题 We have a MFC application setup where a client receives data from server whenever new data is available. Client is being rewritten in C# but communication with server part is in MFC. We have written a C++/CLI wrapper to classes associated with MFC and are able to receive data on application initialization. Communication engine is still in MFC and we have created wrapper classes only for data items. When we initialize the CLI wrapper we copy the data from MFC arrays to CLI arrays. But am not

问题 as I have asked in this question c++/clr StructureToPtr exit application without any exception or error and thanks to the comment, I found out the exit code is -1073740791 , which means Stack buffer overflow / overrun. So let me post my two structures, [StructLayout(LayoutKind::Sequential)] public ref struct ThostFtdcInputOrderField { [MarshalAs(UnmanagedType::ByValTStr, SizeConst = 11)] String^ BrokerID; [MarshalAs(UnmanagedType::ByValTStr, SizeConst = 13)] String^ InvestorID; [MarshalAs

问题 So, I've written a web service in c#, which has a method for signing a hash. This web service is a WCF Service application. Then, I've created a c# Console application where I've written a function to consume this web service. The declaration of the function which calls the web service is that: class Program { public byte[] callWS(string alias, byte[] myHash,string myPassword) { IhashSignSVCClient client = new IhashSignSVCClient(); byte[] signedData= client.SignandReturn(alias, myhash,

问题 I have a piece of code that transform a managed object into unmanaged object as per below, static void M2N(M managed, N* pNative){ Marshal::StructureToPtr(managed, IntPtr(pNative), true); }; my problem is after calling the above piece of code on certain struct , the code exits mysteriously without any exception, the tranformation is obviously unsuccessful (I have tried with some other struct, it works). My question is how can I at least produce some exception, so that I know where went wrong?

问题 when my .net exe runs, it loads the correct .net assemblies at rumtime. i understand that there is a probing process that happens. my question is that if i open up the .net exe/dll in ildasm, i only the .extern reference to the mscorlib.dll, not others. so how does clr gets the information required for doing the probing of the .net referenced assemlies? i have an example project and the images here. so in this case, i dont see the .net assembly references anywhere like System, System.Xml.Linq

问题 Hi am fetching data from sharepoint 2010 list by asmx webservices but when i there is no data in any column it says below error on sql: Lets says "ows_ClientContactPerson" column has not any record then it will give me below error if has then it will not give me error..

问题 I'm implementing application that supports plugins. Currently the problem arises when I try to load common assembly that is used both by host application and plugin: host application should use one version of that assembly, while plugin uses another version. This is dictated by application upgrade process - plugin can be updated separately from host application. Every assembly is signed, so I use strong names for loading assemblies. I created a test application which demonstrates the problem.

问题 i am trying to rebuild a program in CLR C++ from C++ and i get the linker error 1>strmbasd.lib(strmiids.obj) : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86' my project is set to Win32 and the properties are set to target machine x86. i keep rebuilding baseclasses to match the Win32 and I don't know where or why its failing Linker command line looks like: /OUT:"C:\Users\ME\Documents\Code\X C++\Trial2\DirectshowC++\Debug\DirectshowC++.exe" /INCREMENTAL

问题 OK, I realize that SS 2008 doesn't have native regex functions. I also see that it's possible to add them using CLR. I found the regex CLR at http://msdn.microsoft.com/en-us/magazine/cc163473.aspx , but I don't know what to do with them. So I have 2 questions. The regex is only used when importing records (up to 1,000,000 at a time, and up to 50,000,000 a year) against 2 fields. 1st question. I can do it manually 1 record at a time in my code (ASP.NET), and I know it would be a performance

问题 I have a situation where I need to be able to load assemblies in the GAC based on their partial names. In order to do this I have added the following to my app.config file: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <qualifyAssembly partialName="MyAssembly" fullName= "MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef"/> </assemblyBinding> </runtime> This works exactly the way I want it to. However, if I place the same element in my machine
