Hi,
My COM Component has a get method that takes pointer to the struct as input.
but when i use interop it is converted to the value not as pointer.
What happens to the pointer parameters during interop.

Hi,
My COM (unmanaged) COmponent has a get method that returns the pointer to
the array of structures.
When using Interop Services ( i.e convertin to managed code by add refernce)
it shows that get method in managed code is simply returning a strucutre and
not a pointer to the array of structures.
How to solve this issue ?
I need the array of structures to be passed - does it needs to do anything
with boxing and unboxing.
Pls help.

How can I consume a managed dll such as a dll that created by C# in unmanaged code like a MFC project?
|
|
|
|
|
#using <mscorlib.dll>
#using <system.drawing.dll>
using namespace System::Drawing;
...stuff...
you can replace drawing.dll with yours...

I keep getting these errors and I can't figure out why the errors are there.
The line that is throwing these errors is this:
String * pstrDisplay;
BankAccount *pabnkAccounts __gc[];
int pintCurAccount;
pstrDisplay<<pabnkAccounts[pintCurAccount];
I am overloading the << operator like this:
// In class definition
static String *op_LeftShift( String *&, BankAccount * );
// Implementation
static String *op_LeftShift( String *&vstrOut, BankAccount *vbnkAccount )
{
vstrOut = String::Concat("Account Number: ",
vbnkAccount->GetAccountNumber().ToString()),
"\010\013");
return vstrOut;
}
Any help would be great.

Did you put
#include "iostream"
You still need to do this even if you are using MC++
I did this and there was no difference, I got the same error.
cdmlb wrote:
why not use
cout <<pabnkaccounts[pintcuraccount]<<endl;< i="">
I would do this but the BankAccount class is a managed class and I get errors when I try to use ostream in the overload it throws an error saying I can't use unmanaged code in a managed class.
cdmlb wrote:
Console.WriteLine(pabnkAccounts[pintCurAccount].ToString());
I would do something like this, unfortunately it is for school and I have to use the overload method.
I guess that I will have to keep messing around with it. I hope that I won’t have to rewrite the class as unmanaged, but I have to do what I have to do.
Thanks for your help anyway

Well it's weird I write managed and unmanaged code inline all the time. Maybe you could send the file so I can look closer at it.

I could not figure out how to send it to you so I put it online. Here is a link to it:
http://chartermi.net/~reznod/problemcode.zip
The line that is giving me the errors is in 'Part123.cpp' in Part123(), the 3rd case of the switch statement.
I appreciate your help very much.

Hi! I've spent all day trying to figure out how to write a program to talk to a MySQL database. I'm new to the .NET framework, but it seems like it would be straightforward enough. I tried using MySQLDriverCS but it give me debug errors, something about not finding required files. Also, I haven't found a way to get the standard MySQL API working on .NET. So, is there a way to make MySQLDriverCS work for managed c++ or could someone tell me how to setup the MySQL API for Visual C++ .NET?

How would I change the data in a 6x5 char array in selected cells with a variable? i.e.
eeeeee
e
eee
e
eeeeee
How would I change the e's to g's and display the following?
gggggg
g
ggg
g
gggggg
|
|
|
|
|
using System;
namespace MyConsoleApplication
{
class MyClass
{
[STAThread]
static void Main(string[] args)
{
char[,] arrayName = new char[6,5]; //double subscripted array 6x5
//initialize array with e's since
//I don't feel like making a shape
//like you did with e's and spaces
for(int i=0; i < arrayName.GetLength(0); i++)
{
for(int j=0; j < arrayName.GetLength(1); j++)
{
arrayName[i,j] = 'e';
Console.WriteLine(arrayName[i,j]); //print to the screen
//to see if did what I wanted
//to test it out
}
}
for(int i=0; i < arrayName.GetLength(0); i++)
{
for(int j=0; j < arrayName.GetLength(1); j++)
{
if(arrayName[i,j].Equals('e')) //find only e's replace with g's
{
arrayName[i,j] = 'g';
Console.WriteLine(arrayName[i,j]); //print to the screen
//to see if it did replace
//replace all e's
}
}
}
Console.ReadLine(); //pause
}
}
}
It does work, this code will ingore all other char like spaces you made to create the shape and only replace the e's with g's, code works for any mc++, c# application type.

Hi!
Recently i downloaded an article from this page. This project was programmed in C++ with managed extensions and serves as a .NET Wrapper around a existing C++ implementation of random generators and distributions.
I added this project to my solution that consist of a C# windows application. Under VS.NET 2003 everything worked well and i could use the wrapped random generators and distributions.
Unfortunately, i had to move my solution back to VS.NET 2002. My C# windows application still works well, but the downloaded project doesn't get compiled. I receive the following errors, which i noted besides the lines that generate them:
<br />
template<class T><br />
struct ptr_helper<br />
{<br />
typedef T value_type;<br />
typedef T& reference_type;
typedef const T& rvalue_type;
static reference_type ref(T& r) { return r; }
static const T& ref(const T& r) { return r; }
};<br />
This struct is declared in a header-file of the existing C++ implementation that gets wrapped by the downloaded project.
Why can i compile this under VS.NET 2003 but not in VS.NET2002? What i can i do?
THX in advance

Hi, I have program written in C#. I want to use some functions from it. I have DLL, but not sure how I can call that functions from C++ application. If some one can help or direct me to the sample code.
Thanks

Not exactly sure. Try something like:
<br />
#using <mscorlib.dll><br />
#using <System.Windows.Forms.dll><br />
using namespace System;<br />
using namespace System::Windows::Forms;<br />
#using <MyCSharp.dll><br />
using namespace MyCSharp::MyCSharpNamespace;<br />
<br />
int _tmain(int argc, _TCHAR* argv[])<br />
{<br />
#pragma push_macro("new")<br />
return 0;<br />
#pragma pop_macro("new")<br />
}<br />
Don't forget to set Project Properties:
Configuration Properties | General | Use Managed Extensions = Yes
C/C++ | General | Debug Information Format = Program Database (/Zi)
C/C++ | Code Generation | Enable Minimal Rebuild = No
C/C++ | Code Generation | Basic Runtime Checks = Default
Which is a best guess based on Tom Archer's book:
Extending MFC Applications with the .NET Framework[^]
