Hello guys,

I am looking for code analysis tool for C#, something like Compuware DevPartner provides, but hopefully better. Can somebody recommend anything?

The method:

		protected unsafe bool getBinaryAt(int x, int y, BitmapInfo img)
		{
			fixed (byte* scan0 = &img.pixelData[0])
			{
				byte pval = 0;


				byte* pos = scan0 + y * img.Stride + x * getByteSize(img.Format);

				pval = (byte)((*pos + *(pos + 1) + *(pos + 3)) / 3);


				return (pval > THRESH);
			}

		}

Okay, this sort of crosses between C# and Managed C++, but it's valid either way. Here goes.

I'm working on the application side of a project (the other side is the hardware stuff). The hardware is used to interface with stuff across a connection. It uses a struct something like this to move info to and from the app:

struct COMMAND_MSG
{
int msgID;
int msgLength;
char *opCodes;
short range;
};

Pretty simple. So, on the app side, I define a matching .NET type:

__value __gc public struct M_COMMAND_MSG
{
System::Int32 msgID;
System::Int32 msgLength;
System::Byte opCodes[];
System::Int16 range;
};

Here's where the problem comes in. I can't figure out how to marshal this type so that an unmanaged function could map it into the unmanaged struct type. Marshaling the type into a buffer I can pass as a void* is pretty simple, normally, involving something of this ilk:

IntPtr buffer = Marshal::AllocHGlobal(64);
Marshal::StructureToPtr(__box(testStruct), buffer, true);

That gives me a buffer that I can shoot to an unmanaged function (as buffer.ToPointer()). But with that array, something isn't happening properly. When the buffer gets to the unmanaged function, the unmanaged type isn't mapped correctly.

What am I doing wrong?

This is probably an incredibly dumb question, but for the life of me I can't find it in the help. I'm probably using the wrong search terms.

I'm using C# 2005 Express Edition. Putting together a Windows form that has three separate sections. I'd like to draw a simple horizontal line, like a separator, between each section, but I can't for the life of me figure out how.

Anyone?

Thanks.

Let's say we have method like this:

void DoIt()
{
    lock (this) { DoItSafe(); }
}

[MagicAttributeOrKeyword] 
void DoIt() // works the same as the first snippet
{ 
    DoItSafe(); 
}

Whenever I try to compile a C# file from Visual Studio Express 2005, I get a warning:

"Invalid search path 'C:\Program Files\Microsoft Visual Studio .NET 2003\SDK\v1.1\Lib\' specified in 'LIB environment variable' -- 'The system cannot find the path specified. '"

Well, not surprising, as VS2005 is supposed to be using v2.x, I would have thought. But where do I change the library path? The projects don't have any library path specified, so it must be a global setting somewhere, but where?

TIA,

Tim

Okay, I'm stumped.

I'm using Intersystems Cache, for which there seem to be no peer help fora anywhere on the net, though theoretically it shouldn't matter, should it? ODBC is ODBC, I hope. In any case, here's a quick code snippet:

       private void btnSave_Click(object sender, EventArgs e)
        {
            try
            {
                string InsertString = "INSERT INTO Erasmus.Publisher(Name, PublisherURL) VALUES(@Name,@URL)";
                ErasmusTransaction = ErasmusConnection.BeginTransaction(IsolationLevel.ReadCommitted);
                ErasmusInsertCommand = new OdbcCommand(InsertString, ErasmusConnection, ErasmusTransaction);

                OdbcParameter prmName = new OdbcParameter();
                prmName.Direction = ParameterDirection.Input;
                prmName.OdbcType = OdbcType.VarChar;
                prmName.Value = txtName.Text;
                prmName.ParameterName = "@Name";
                ErasmusInsertCommand.Parameters.Add(prmName);

       private void btnSave_Click(object sender, EventArgs e)
        {
            try
            {
                string InsertString = "INSERT INTO Erasmus.Publisher(Name, PublisherURL) VALUES(@Name,@URL)";
                ErasmusTransaction = ErasmusConnection.BeginTransaction(IsolationLevel.ReadCommitted);
                ErasmusInsertCommand = new OdbcCommand(InsertString, ErasmusConnection, ErasmusTransaction);

                ErasmusInsertCommand.Parameters.Add("@Name", OdbcType.VarChar, 100).Value = txtName.Text;

Heya all, I'm working on a web-based application (using ASP.NET and C# on .NET 1.1.4322, supporting only IE6 for Windows) that allows for file uploads. It seems to be a universally agreed that the file upload control is as ugly as they come, so I want to set its style to "display: none;" and interact only with the standard file upload dialog (which can be summoned by firing the click() method of the control, which is exposed under IE6 but not recent versions of Mozilla).

Attempting programmatic access of a file upload control is generally playing with fire, and this time is apparently no exception. Once I call the click() method, it seems, the page is no longer able to post back. When I attempt to submit the form, the value of the file upload control is cleared and the page just sits there. However, if I make the file upload control visible and manually click its "Browse..." button, the page posts back correctly.

For those of you familiar with Gmail's attachment upload interface, this is very close to the effect I am trying to achieve, but something about ASP.NET is apparently interfering (perhaps for my own protection) with the process. Has anybody experienced similar behavior under the same platform, and if so, explain the behavior or point to a KB article or security documentation that might be enlightening ? Thanks greatly for your time. Toy code can be found after the cut.
