Hi,
It's about 5 day that I'm traying to create a MixedMode DLL with MFC and Managed C++. At this time I'm freak I don't really know what I'm doing. I have read a lot of documentation and I still confuse.
With more detail, I want to create an MFC Regular DLL that can be accessible in C# and from an other MFC application.
If any body have a good tutorial or a small project that implement the DLL, an application in MFC and an other application in C#.
Thank for your help.

When i declare :
EventLog* log2 = new EventLog();
it's write error about (*)??
Thank you
|
|
|
|

Perhaps if you told us what the error is ?
If EventLog is a managed object, I thought you needed to use gcnew ?

I would GetHostName and show him in treeView, i work with winforms, i try for

treeView1->Nodes->Add(er);

error C3867: 'System::Net::Dns::GetHostName': function call missing argument list; use '&System::Net::Dns::GetHostName' to create a pointer to member
Thank you

GetHostName is a static method:
String^ hostName = System::Net::Dns::GetHostName();

I know the answer to this may be obvious but I have been struggling with it for about 8 hours now and just can't figure it out and my googling and other searchs have not yielded an answer.
I'm writng a managed C++ program in VS 2005 that is using some c# assemblies. I have one c# assembly method that has a signature like this:
public virtual void DoThis(string title, out Object valueToChange);
I have an example where some c# code is overriding the above method and the signature in the subclass is:
public override void DoThis(string title, out Object valueToChange);
In my C++ code I just cannot get my program to use my overriden implementation of this method. I have tried the following signatures in C++. None of them seem to match according to what I see in the debugger.
public virtual void DoThis(String title, Object % valueToChange);
public virtual void DoThis(String^ title, Object ^% valueToChange);
public virtual void DoThis(String^ title, Object ^ valueToChange);
public virtual void DoThis(String title, Object valueToChange);
public virtual void DoThis(String title, Object^ valueToChange);
public void DoThis(String title, Object % valueToChange);
public void DoThis(String^ title, Object ^% valueToChange);
public void DoThis(String^ title, Object ^ valueToChange);
public void DoThis(String title, Object valueToChange);
public void DoThis(String title, Object^ valueToChange);
What is the correct way to override an "out" c# method parameter in c++ code?
Thanks for any help

Have you tried:
using namespace System::Runtime::InteropServices;
...
public:
virtual void DoThis(String^ title, [Out] Object^% valueToChange) override;

Wow thanks so much! I did have to change 1 part of what you suggested to get it to work (No ^ on the 1st param) but now I am so happy. I had wasted so much time on this problem. I didn't know about the InteropServices namespace before. I'll have to read up on it.
public:
virtual void DoThis(String title, [System::Runtime::InteropServices::Out] Object^% valueToChange) override;
Thanks,

You could set Value to 0.

I have developed a text editor supporting international languages.
One problem still bother me: The location of the IME window.
When I have an asian user entering asian characters, (s)he does so through an IME window which is located in a seemingly unpredictable/uncontrollable location.
Is there a way I could set the location, size, and font (or at least font size) used by this IME window?
How could I know when it is used or not?

I would use listView, but i don't know how ican add 2 item i try:
istView1->Items->Add(cli::array<string^>^ tabChaine = {"Element 1", "Element 2"});
but there are errors,Thank you
|

|

What are the errors?
I don't see a ListView.ListViewItemCollection.Add overload that takes a "cli::array^" as an
argument.
Also managed object references don't work like C++ pointers so this won't work:
cli::array^ tabChaine = {"Element 1", "Element 2"}
Have you seen the example code here[^]?

However, the below code works but not in the context our friend was using it in.
array<String^>^ items = {L"Hello", L", ", L"world!\n"};<br />
<br />
for each (String^ item in items)<br />
{<br />
Console::Write(item);<br />
}

Hey guys, it has been a while /cry. I seem to be having some issues with comparing values in a file, such as finding the highest value in a file in mixed order and outputting to a file in correct order. I have a file created with the following text 4,3,1,2, my object is to find the highest value then output to a file in correct orsder to 1,2,3,4. This is all I have and I am a little rusty cause it has been a while:
// iofilecomp.cpp : Defines the entry point for the console application.
// iofilecomp.cpp : Explains how to copy the contents from one file to another.
//
#include "stdafx.h"
#include <conio.h>
#include <string>
#include <fstream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
ifstream ins; //reads from file
ofstream ous; //writes to file
ins.open("in.dat");
ous.open("ou.dat");
string line;
if( ins.is_open )
{
while ( ! ins.eof() )
{
getline(ins, line);
cout << line << endl;
}
ins.close();
}
else cout << "Unable to open file.";
ous.close();
_getch();
return 0;
}
The above will only output in the order read from the file. Possibly could I get some assistance or pointed in the right direction please. Thank you.
