hi
before posting this question only i checked all the above things which u said.
it is showing perfect 12 records dtable.rows.count in immediate window
when i am binding the same to Datagridview also, the dgrid.rows.count is 12 only..
but it is not showing the 12 records in grid, instead of 12 it displays only 1 record..
Let me know if u have any solution..
Thanks and Regards,
Pawan.

That depends largely on what you mean with "assembly code";
- If it's code that's stored in an assembly, then simply load it.
- Assembly might also refer to IL, which is explained here[^]. That's specific to the .NET VM.
- If you're referring to plain old assembler, then I'd suggest you install Turbo Pascal.

You can't directly. .NET uses a form of intermediate language which is intended to be target neutral. If you want to use assembly code, you need to look at writing your application either in assembly, or in C/C++. .NET is entirely the wrong choice here.

Yeah, can't be done directly, but I would guess it can be done. Create a C++ project that uses "__asm {...}", reference that project from a managed C++ project, then reference that project from a C# project. Might have to mark some functions as "unsafe" or something, but I would guess something like that would work.

Wouldn't there be a more direct way? Such as doing the __asm part in C++/CLI and merging it with the compiled C# with ILMerge? (would that work?)
|
|
|
|
|
I thought ILMerge only worked for IL assemblies. C++ with assembly code would compile directly to machine code. Would ILMerge still work then? And even if it did work then, I don't understand how that would make things more direct than creating a few projects and having a couple references in Visual Studio.

That's why I was planning C++/CLI, it makes mixed assemblies right?
At the very least, mixed assemblies exist in the wild, even though I'm not sure how they were made..

I suggest you stop trying to write your piece of malware (which is really the only thing it can be, if you want to disable interrupts)
|
|
|
|
|
Why in the world do you think the OP is creating malware or is trying to disable interrupts? Did the OP modify the question, because I don't see any mention of disabling interrupts. There are many uses for assembly language in higher level languages, usually relating to performance. For example, at the bottom of my SlimList article, I mention that I can use BSR (an assembly command) to do a quicker base 2 integer log calculation than would be possible using plain C#.

yes it can be done using c++ project wrapper then you would add reference to that dll into .net ,
but be careful , when you do so , you lose the portability that microsoft struggles for when it creates .NET technology , it can't be run on different OS because your embedded assembly code will be targetted for specific platform .
Requirements to create the c++ wrapper dll
1 - Decorate the method in c++ as "extern" to stop the compiler from changing the method name when you compile your DLL .
2 - you can even call the dll methods without using unsafe declaration , because it will be treated like any dll referenced in .NET project.
i hope this helps

Strictly speaking, you can't as others have said.
However this thread[^] says that you can use simple assembler instructions inline. WARNING You have to register to download the code. No personal details are required though.
I also doubt that it compiles down to a binary file, don't know because I haven't looked at it myself yet. Still it might be fun even if not actually useful.

How can I write sql sentence with byte[] parameter?
NOTE: I don't want to use SqlParameter.
string sql = "INSERT INTO MyFile(FileId, BinaryFile) VALUES('" + fileId + "','" + file + "')";
....
command.ExecuteNonQuery();
fieldId is int variable, file is byte[] variable.
In database; FileId is int field, file is varbinary(MAX) field.

I don't want to use SQL Parameter. I use MS SQL.

Tough, you have to. And it's the right thing to do, every time.

First of all, please don't use sql like this. As you are using SQL Server, you should really use command parameters (this helps circumvent SQL Injection Attacks). Then you could set the data easily, as detailed here:
using (SqlCommand cmd = new SqlCommand("MyFile(FileId, BinaryFile) VALUES(@fileid, @file", connection)
{
cmd.Parameters.AddWithValue("@fileid", fileid);
cmd.Parameters.AddWithValue("@file", file) ;
cmd.ExecuteNonQuery();
}

That's like saying you want to swim but you don't want to get wet. Maybe if you tell us your reasons why you don't want to use a parameter object we could help you with a solution that better fits your needs. Otherwise it isn't worth coming up with an answer because who knows what other objects you refuse to use for no apparant reason.

Like other have said, unless you're really experienced with SQL, you should use parameters (and even if you are really experienced, it's still a good idea).
The first problem is you appear to be using the wrong data type to store bytes. VARBINARY is a character type to store binary strings (useful for forcing case sensitivity, IE, 'a'='A' in a char type, but not a binary type) - http://dev.mysql.com/doc/refman/5.1/en/binary-varbinary.html[^] You probably wanted a BLOB type of some kind.
As for storing byte[] with an SQL statement, converting the bytes into a hexadecimal string value should work -
INSERT INTO (FileID, Data) VALUES (1, 0x0F2EAA32);

Even if you manage to do that (which you won't, you'd need to execute cli in ring 0, how to do plan to do that?) you would completely break windows. Not good.
Why do you think you need to do this?
