Post the compiler error messages, otherwise we have to guess.
Obvious things to check:
Do you have properly configured "mixed mode" project settings?
Do you have required #include and import statements?
If you don't know what one or both of those are you need to use MSDN to read about "mixed mode" development.

Hi,
My current Project has the following Requirements:
1. Backup the entire contents of the hard disk including Operating System as a bootable Image.
2. In case of System Failure, user should be able to perform a full system-recovery operation using the Backed up Image of the Hard Disk.
I am new to this concept and request any sort of help on how to proceed with this.
Any help will be greatly appreciated..
Regards

That is generally considered too broad a subject or too vague of a question to receive a meaningful reply in a forum. You could probably write a book chapter or several on a subject of that scope. You might have to do some reading until you have broken down your problem into it's constituent parts. The post small specific questions to obtain help in a forum format.
But, that's just my opinion... I could be wrong.

Okay, I'm a little confused. So, the ANSI / ISO Standard C++ is
a stardard C++ lanugage that targets non .Net platform and
managed C++ is designed by Microsoft that targets .Net platform.
Code that generated by using the ANSI C++ is also called native code or unmanaged code
and code that generated by using Manage C++ is called managed code.
Is that right?

Mostly. However Non ANSI / ISO Win32 C++ code is also considered "native" in discussions of "managed" C++.

Hi all,
I got a problem with Return key in my C++/C# application.
On CView dilalog I put my C# control using managed extension. This C# control has couple
other controls nested. I have problem with RichTextBox control which
is at the bottom of my control hierarchy. It does not process
VK_RETURN key down. So I can not create new line. All other keys work
in RichTextBox. Of course I made it Multiline. I used Spy++ tool to
figure out what is going on. I managed to see that RichTextBox window
receives ON_KEYDOWN message with VK_RETURN. But there is no WM_CHAR message which normally should follow WM_KEYDOWN. As a result no new line is created in RichTextBox.
Tried to catch WM_KEYDOWN in WndProc and onkeydown. But they are hit for all keys except of RETURN
I would greatly appreciate any hints.
Thanks in advance,
Roman

So your C# control is not receiving the VK_RETURN event notification? Try asking in the C# forum.

Just found solution.
In overriden WndProc I listened for WM_KEYDOWN message and never got it. But in reality I should have listened for WM_GETDLGCODE.
After I caught the message I could insert new line in textbox manually

Hi everybody
If can anybody help me with checking the "Change" in the Status register of the Parallel Port, i want to use it to check a clock from an external device periodically, also i want to know if i can stop the interrupt to the Microprocessor while i'm using the parallel Port
Thank you everybody and have a nice day

Parallel port is usualy on 0x378 adress and it's registers are: controll 0x379, status 0x37A, so you just ned to read from adress 0x37A something like clock_status = inportb(0x37A) or something elese. Note that you can not use inportb function on NT based systems before you use some driver (there is a lot of that stuff) that will allow you direct accsess.

I'm looking for some help in coding an application where I need to share some data between two threads. The first thread is managed code and it launches another thread that is unmanaged code. Can someone point me to an article, example, etc. on how to do this?
Thanks.

Hi,
I have imported several unmanaged C++ LIBs into a mixed C++ .NET DLL.
Two LIBs have the SAME class name (CLog) without namespace.
Is there a way to assign a namespace to each imported LIB in the mixed DLL project?
Also, when I use this mixed DLL in my C# app, I can see that these unmanaged classes (from LIBs) are shown :
how can I set the visibility of the classes to something like "internal" (as in C#) in the Mixed DLL ??
Thanks a lot!

Hello,
As a newbie to MC++, i've been working on a C# API that accesses a class written in C++. I've converted my C++ class into a wrapper as was suggested to me, but now i have an incredibly frustrating problem: when i try to "set" parameters into the attributes in the C++ class, i get datatype conversion problems. namely, here are my errors:
Argument '1': cannot convert from 'decimal' to 'int'
Argument '2': cannot convert from 'string' to 'std.basic_string<char,std::char_traits<char>,std::allocator<char> >*'
Argument '3': cannot convert from 'char' to 'sbyte'
I don't know how to get arnd these issues -- are there any "common" datatypes between the two languages? Any help would be REALLY appreciated
thanks in advance
|
|
|
|
|
Actually i just found something that could be "common":
The C++ "char" == the C# "sbyte"
not pretty, but it does the trick
|
|
|
|

If you are going to mess with C++ let alone "mixed mode" development you need a very clear understanding of "types" in C/C++ and "type conversion" principles.
But, that's just my opinion... I could be wrong.

I am trying to build a DLL but every time I build my project it gives me an EXE. I have set the configuration type to 'Dynamic Library (.dll)' but it still only gives me an EXE.
I appreciate any help.

If you are using Visual Studio, check the entry of your output file.
You can find it in the project properties, in the Linker section, below the "Common" section (sorry, if the section - titles are called a bit different in the english version of VS.NET, but I'm using the german version ...)

It worked, thank you very much.

Hello,
I am trying to save an image stream into a .bmp file or a jpeg file. I an trying to use the .NET classes in the System::Drawing namespaces.
I have some code like the following
<code>
char* buf = new char[bufSize];
dev->Grab(buf);
Byte b[] = new Byte[bufSize];
MemoryStream *ms = new MemoryStream( b );
for(int i=0; i<bufSize; i++)
{
b[i]=buf[i];
}
Bitmap *b = new Bitamp( ms );
b->Save(S"C:\\test.jpg", ImageFormat::Jpeg);
</code>
Every time i run the code the following line
Bitmap *b = new Bitamp( ms );
throws a ArgumentException:Invalid Parameter used exception.
Does any one Know Why, could it be that the Bitmap class understands that the stream is not a valid image yet because the stream only contains the row bytes... any help please...
