I'm not familiar with the managed extension ... did you try copying the C buffer of the std::string ? something like : std::string s; yourSystemStringVariable = s.c_str();

My code is; #include "stdafx.h" #include "SysInfo.h" #using #using using namespace System; using namespace System::Data; using namespace System::Net; using namespace System::IO; using namespace System::Text; using namespace std; int _tmain() { SysInfo sysInfo = new SysInfo(); String* uriString; String* postData; uriString = "http://localhost/WebApplication3/WebForm1.aspx"; WebClient* myWebClient = new WebClient(); myWebClient->Headers->Add(S"Content-Type", S"application/x-www-form-urlencoded"); //postData = Convert::ToString(sysInfo.getCpuModel()); postData = sysInfo.getComputerName(); Byte byteArray[] = Encoding::ASCII->GetBytes(postData); Byte responseArray[] = myWebClient->UploadData(uriString, S"POST", byteArray); Console::WriteLine(S"\nResponse received was {0}", Encoding::ASCII->GetString(responseArray)); }

visibly, you are trying to assign a string* with a string. didn't you forget the address operator (**&**) ?

i don't for your answer, but i'd like to give some advices. ozgul wrote: using namespace System; using namespace System::Data; using namespace System::Net; using namespace System::IO; using namespace System::Text; if you are using System::, you don't have to using parts of it... you can so delete the 4 lines following. ozgul wrote: uriString = "http://localhost/WebApplication3/WebForm1.aspx"; in general, we are talking about URLs, not URIs. at last, where does your code crash (about what line) ???

I assume you have a problem with the following line! postData = sysInfo.getComputerName(); Is this correct!? Everything else looks fine IMO. You should change it to read postData = sysInfo.getComputerName().c_str(); Ant. I'm hard, yet soft.

A lot of thanks.... I changed this line postData = sysInfo.getComputerName(); with postData = sysInfo.getComputerName().c_str(); Then it worked very well. Again thanks every body...
