How do I DeSerialize a file in C++ .NET (e.g. using BinaryFormatter) that was originally created by Serialized in an MFC appliction using CDocument::Serialize?
When trying to do this, I get:
BinaryFormatter Version incompatibility. Expected Version 1.0. Received Version 1684632134.539785569.
Thanks!

I doubt that it's possible this way.
CDocument has one format to serialize data and BinaryFormatter has another one. Just stuffing the output from one class into the other one doesn't work. You'll also fail when you let CDocument deserialize a file created by BinaryFormatter.
Both CDocument and BinaryFormatter write some header information into the target file (or try to read it back in), at least containing some kind of version information, but the structure of this header is different, thus the error.
Besides, IIRC CDocument doesn't add type information to its output but I think BinaryFormatter does (but don't quote me here  )
I don't see a chance to achieve this without developing a class to read in a CDocument-generated file manually...

Did anyone work with this thing?
Does anyone know if it works with .NET 2.0 beta 1?
(It's a 300MB download, so I would like to know if it works with .NET 2.0 _before_ downloading it?  )

Related to OLE Automation which we used in Visual Studio 6 and earlier versions. I want to know what is the replacement for In-place Activation in .NET environment. I mean how can I make my application to be an OLE Container. Ideas required
Think Negatively, It makes you creative

There's no simple ole container control in the framework, as far as I know, but using the WebBrowser control to host an OLE object could work.
I found an article on this topic on MSDN.

What's puzzling me for a while now is how the RichTextBox behaves when you add text at the end programmatically.
When you have a RichTextBox and call:
richTextBox1.SelectedText += "\nHello World!"; you'd expect it to be the same as calling
richTextBox1.SelectedText += "\n";
richTextBox1.SelectedText += "Hello World!"; wouldn't you?
Now the funny thing is that the first piece of code keeps the current font for "Hello World!" and the second one switches back to the RichTextBox's default font!
Anyone has a faint idea what's going on here or how to keep the RichTextBox from doing this?

Hello, I am a newbie in interoperability, and I met a problem with SAFEARRAY in inter-thread communication; unfortunately, I found nothing close to this problem on the Internet.
To summarize:
I have exposed .NET classes to COM clients, one of the classes has an array has returned method value. And in COM (C++) it seems that passing a SAFEARRAY of n "myObject" from a worker thread to a UI thread fails whereas passing n times a single "myObject" works perfectly.
I want to know if something must be done on the c# array which is exposed to COM to solve that.
For those who met this problem (or are courageous), here are the details:
In C#, I have 3 classes "MyObject1","MyObject2" and "MyObject3".
"MyObject1" has a method which returns an array of "MyObject2": public MyObject2[] getArray();
"MyObject2" has a method which returns an instance of "MyObject3": public MyObject3 getObject3();
"MyObject3" has several methods which returns its id, name...
Now, I expose this managed code in a dll to unmanaged code, C++, with .NET framework interop fonctionalities.
In C++, I get:
"MyObject1->getArray()" has a safearray of MyObject2 as returned value
"MyObject2->getObject3()" has MyObject3 as returned value
Great! My managed code is exposed to COM clients!
Now the bug:
In C++, I have 2 threads "UI" and "worker", both are COINIT_APARTMENTTHREADED.
1. I create an instance of "MyObject1" in the UI thread
2. I pass this object to a worker thread method through a queue list
3. In that worker thread method, I call "MyObject1->getArray()" and get the SAFEARRAY of "MyObject2" as returned value
4. I pass back that safearray to a method callback of the UI thread
5. In that UI callback, I want to iterate on the safearray: for each "MyObject2" of the array, I call "MyObject2->getObject3()", then a method of "MyObject3"
-> bug: whatever the method of "MyObject3" which is called, it fails: it seems that "MyObject3" has a problem.
I have made some extra tests:
1. Test1: I put COINIT_MULTITHREADED to UI AND worker: no problem. But this patch cannot be used.
2. Test2: if I do steps 2-to-5 in the worker thread (which means I iterate the safearray in the worker thread, and never go back in the UI): no problem
3. Test3: if I do steps 2-to-5 in the UI thread (which means I never go into worker): no problem
4. Test4:
At step 3, I iterate on the SAFEARRAY. For each "MyObject2" of the array, I pass it to an other callback of the UI. Then, in the UI, I call "MyObject2->getObject3()" and then any methods of "MyObject3", and it is working!
That means that passing a SAFEARRAY of n "MyObject2" from worker to UI fails when we want to retrieve objects from each "MyObject2", but passing n times a single "MyObject2" works perfectly.
I wonder if I have something to add to my C# code so the marshalling/unmarshalling of the array works between threads.

Hi,
I'm trying to write a serial port communication in Windows CE.NET ,
but when i call the 'CreateFile' method of the Kernel32 i get an unidentified exception.
The problematic function is :
"m_hFile = CreateFile(port, (uint)((m_bRead?GENERIC_READ )|(m_bWrite?GENERIC_WRITE )), 0, 0, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, 0)"
And i send "COM1:" as the name of the port.
Does anybody know how to develope a .NET base class library for serial port
communication in Windows CE?
Thanks,
Shay.

Hi,
I am trying to create a browser that i can use to capture GET and POST requests in C# (.Net framework).
I use the Microsoft Web Browser component to do the same. I register events like NavigateComplete2, BeforeNavigate2 and DownloadComplete but none of them provide me with complete POST headers.
The "header" member just provides
Content-Type: application/x-www-form-urlencoded
and nothing else.
I do not wish to use the HTTPRequest class because i want to support SSL based connections also.
Can someone please give me pointers on how i can get all the header values for every POST request. If there are any event handlers i can use please let me know.
Any kind of help will be much appreciated.
Kind Regards,
Shanit.

What you need to implement is a packet sniffer. A packet sniffer, 'sniffs' all the data sent via a port from an ip address OR data SENT from an ip address.
However, since SSL encrypts the channel all you get is the encrypted data. A good example of this is Ethereal[^].
Read this article (from CP!) about more information on a C# Packet Sniffer.
Hope this helps!

Hi~

"I have 2 forms, form1 contains a ListView. What I want to do is, when

But when mouse up, system redrawed the selected item and bring title and menu back to form1's. I tried to handle MouseDown and MouseUp event of ListView but they were never triggered. Now I used a tricky way to solve the problem: start a thread and use Control.Invoke to switch forms. It is not good, I think there must be a better solution. Thanks."
I am facing the same problem. Someone solve it with setting timer. However, is there any other way to solve it?

Hi
I have developed a PocketPC application - I have a Client that calls WebServices (uses .NET Compact Framework) and I have a Server that publishes the web services.
I want to make sure that the same Client application ports to SmartPhone.
What changes do I have to do to the Client Code, and to the WebServices code in the server? Would the same webservices work for both? If not, how does the server detect who is calling the web service - the PocketPC or the SmartPhone?
Please help
Thanks

Hi!
I am developing a mulititier application.
I created some value classes with custom attributes specification.And i have seperate query builder class.This query builder class will construct the query based on the valueobject.Internally the query builder using reflection
reads all propertie's name and custome attributes.Upto that there is no problem.If i try to fetch the value of a property then the runtime error will occurs.For fetching the value i am using PropertyInfo.GetValue method.
So please any on help me to resolve this problem..
Type type=Obj.GetType();
foreach(PropertyInfo f in type.GetProperties())
{
foreach(Attribute attr in Attribute.GetCustomAttributes(f))
{
if(attr.GetType()==typeof(DefaultValueAttribute))
{
str+=":"+f.Name+":"+((ColumnMappingAttribute)attr).Name;
str+=f.GetValue(null,null); --This line shows error
}
}
}
Please help me to solove the problem

If you would have read teh documentation for PropertyInfo.GetValue
you would have seen that the first parameter to it is the
"The object whose property value will be returned.".
If you read the Remarks section there, it says
"Because static properties belong to the type, not individual objects, get static properties by passing a null reference (Nothing) as the object argument."
But since you're trying to retrieve a non-static property that line should look like this:
str+=f.GetValue(obj,null);
So next time instead of "Waiting for 2 days" try "Reading the documentation for 5 minutes"
