I think you're in the wrong forum, this is for C++/CLI, I think you want Visual c++.

Christian,

We need to change the name of this forum to "This Is not the Visual C++ Forum". OMG | :OMG:

Hmm. Never mind! If we did that, we will get an increase of unrelated posts. Sigh | :sigh:

I suspect a lot of people see 'visual c++' and assume MFC, and have no idea what 'managed' or 'CLI' means, so they just ignore it.

Dear all

My company has a fax server pool that contains 16 faxes cards. We are using the HylaFax software http://www.hylafax.org/content/Main_Page[^] Which written in C language.

Now that software is good in that when a fax is coming, it transfer it to the correct card (tha card that is specified for the recipt)... But, when we send a fax, it handles tha job to the next available card in the Queu (not nesesarly to be the card that is specified for the sender).

If anybody knows how to enhance this software so it sends the fax correctly(using the sender card) I will appreciate his/her help.

Or if you have an alternative solution that not expensive to use. I will also appreciate that.

Best Regards

Then you can't possibly modify it using C++/CLI. If you want to know how to change this code, your best bet is the Visual C++ forum, although even that is a long shot. You probalby want forums dedicated to users of this particular software.

I am using visual c++ 6.0. I wish to use the COleVariant::GetByteArrayFromVariantArray member function
but the compiler generates error message : GetByteArrayFromVariantArray is not a member function of COleVariant. Why could this happen?? Is this function available only in VC++ 2005??

Is there any way to retrieve a byte array from variant array??
Thanks. I will appreciate any help from you.

System::String^ to const WCHAR* ?

Then you're plainly not using C++/CLI. Try the Visual C++ forum.

I am trying to write an app which requires me to convert a String^ to a WCHAR but not having much luck with a resolution.

Can anyone point out where I am going wrong ?

I'm using Visual Studio 2005 and it's a console application.

G'Day led mike,

Well, ya could be right despite the fact I have tried a number of times creating different search strings in the hope I may find something that steers me in the right direction.

I am pretty new to C++ as I have recently come across from using Borland's Delphi, so I will use that as my excuse. Smile | :)

That is easy to believe. Keep at it though. Developing the "skill" to find information is a critical skill in our field. If this helps at all, I use Google to do my searching and when I expect that MSDN will contain the information I seek I put "MSDN" as the first keyword in the Google search phrase. I find that Google provides much better results than the MSDN search engine. But that's just me. Big Grin | :-D

Anyway using your question as an example my Google search string would be

MSDN System.String convert WCHAR

Try it out.

I hope this example helps:

#include <iostream>

using namespace System;
using namespace System::Runtime::InteropServices;

int main(array<System::String ^> ^args)
{
String ^gcString = L"Hello, World!";
IntPtr intptr = IntPtr::Zero;

try
{
intptr = Marshal::StringToHGlobalUni(gcString);

const wchar_t *hgString =
static_cast<const wchar_t*>(intptr.ToPointer());

std::wcout << hgString << std::endl;
}

catch (Exception ^e)
{
Console::WriteLine(e->Message);
}

finally
{
if (intptr != IntPtr::Zero)
{
Marshal::FreeHGlobal(intptr);
}
}

return 0;
}

I use this easy way, but it is not recommended for large strings.

String ^s = "Hello world";<br />
CString str = s;<br />
WCHAR *w  = str.GetBuffer();<br />
WCHAR *myChar = new WCHAR[str.GetLength() +1];<br />
memcpy(myChar,w,str.GetLength()*sizeof(WCHAR));<br />
myChar[str.GetLength()] = '\0';<br />
<br />
// Just display the WCHAR			<br />
AfxMessageBox(myChar);

29-Nov-06 15:37

In C++, the storage class specifiers auto, static, register, extern, and mutable. The storage class specifiers explicitly determine the storage class of a variable. Thus, the storage class specifier, auto, lets you define a variable with automatic storage (storage class). However, you will also hear: auto storage class. So, storage class and storage class specifier may be used to mean the same thing.

According to your profile, you program with C++ and not C++/CLI. Also, your plea for help does not give me enough information to assist you. What are your requirements? Here is an example of how your plea for help sounds to me:

Run an Exe from Windows service

Hi ,
My problem is that, I want to run an .exe from the windows service. But the application window is not visible to the user. Exe and Service is running in task manager. Previously I was using CreateProcess funtion. Then after getting suggestion from this site, I changed that into CreateProcessAsUser and the Code is like below. But Still I am facing same problem.

BOOL b;
HANDLE hToken;
HANDLE hNewToken;

b = OpenProcessToken(GetCurrentProcess(), TOKEN_ASSIGN_PRIMARY|TOKEN_DUPLICATE, &hToken);

b = DuplicateTokenEx(hToken, TOKEN_ASSIGN_PRIMARY|TOKEN_ALL_ACCESS, NULL, SecurityImpersonation, TokenPrimary, &hNewToken);

b = CreateProcessAsUser(hNewToken, NULL,ArgPBU,NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS | CREATE_NEW_CONSOLE, NULL, Cwd, &si, &m_piPBU);

CloseHandle(hNewToken);

-------------
After executing this I am getting same result.

Rgds.,
