Marshal of C++ char[] to C# string

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :.NET Framework
Hi guys, this is my problem. I have some C++ structure in unmanaged DLL. I need to use those structures in C#, in managed code.It seems all simple.... This is the C++ code of structures. Be careful to the structure "T__KRON_Struct_Error_Context" that is the structure that causes problems. ****************************  typedef char                    T__Char; typedef unsigned __int32        T__UInt32;  typedef enum {  KRON_ERR_SUCCESS       =1000,   KRON_ERR_RQC_DUPLICATED      =1601,  KRON_ERR_RQC_BAD_CONF_FILE     =1700, }T__KRON_Returned_Codes;  typedef struct {  T__KRON_Returned_Codes m__errorcode;  T__Char     m__errormessage[150];  T__Char     m__errorfile[256];  T__UInt32    m__errorline; }T__KRON_Struct_Error_Context; ***************************** My marshaling of structures in the C# Wrapper is the following:     [System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential, CharSet = System.Runtime.InteropServices.CharSet.Ansi)]    public struct T__KRON_Struct_Error_Context    {        public T__KRON_Returned_Codes m__errorcode;        /// T__Char[150]        [System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.ByValTStr, SizeConst = 150)]        public string m__errormessage;        /// T__Char[256]        [System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.

P/Invoke: char[] or string?

From a .NET Compact Framework (that's why coredll is used) code: [DllImport("coredll", EntryPoint = "RegCreateKeyExW", CharSet = CharSet.Unicode)]<br/> internal static extern int RegCreateKeyEx(<br/> uint key,<br/> char[] subKeyName, // or prefer string?<br/> int reserved,<br/> string className,<br/> int options,<br/> int samDesired,<br/> ref int securityAttributes,<br/> ref int result,<br/> ref int disposition); Both version seems to work (string and char[] ). Which advantages/disadvantages to they have? Which should I prefer? In the sample above string is used for className parameter but char[] for subKeyName which looks a bit strange for me.Programming is a kind of art but not all programmers are artists.

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Membership Provider Conn String


Hello. I've bee successfully using the Asp.Net Membership Provider in my VB.Net 3.5/SQL 2005 web app for a year now (Site A). However, I've added 2 new sites (B and C) (both with their own DB) and now I see a problem. It looks like users that get created for sites B and C also get created in site A. Roles that I create for B and C only get created in A. I think it is a conn string problem.

When I created A, I adde the conn string to my machine.config (not sure why I did this or if it is even needed)...


         <add name="LocalSqlServer" connectionString="Data Source=VS689\SQLEXPRESS;Initial Catalog=SiteA;USER ID=sa;PASSWORD=123456"/>

Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";
