How to convert these code to C#? Thanks!
memset(m_bParameterData, 0, sizeof(m_bParameterData));
Float2IEEE((float)EXTERNAL, m_bParameterData);

The memset is there to clear out the memory that the pointer is pointing to. I believe you should be able to ignore that here.
As for the other function, I have no idea what it is. Where was it being used before? Is it in an external DLL?

Hi all,
In my case, i am getting the datatable(dt1) and then bind to gridview (gv1). And in the gv1 i am already add the TemplateField(checkbox) for each rows.
My question is how can i delete the datarow according the checkbox(if checked) in the gv1 ?
any helps are welcome.

Assuming that you are actually using a DataGridView.
Iterate over the Rows collection, and delete those that have the CheckBox checked.

I would like to know how to detect through c# programming if Acrobat Reader or Adobe Acrobat Professional is actually running.
Thanks a lot.

System.Diagnostics.Process[] processes = System.Diagnostics.Process.GetProcessesByName("AcroRd32");
if (processes.Length >= 1)
{
Response.Write("Acrobat Running");
}
else
{
Response.Write("Acrobat Not Running");
}
can we get the reference of the file for which the AcroRd32.exe is applied. If so, How?

Hi everibody
I'm trying to make a simple drag and drop of strings between 2 list (or other control wich is appropriate), but I can't succed to realize this. I looking for a tutorial, or a guide wich can explain to me how to implement this simple functionality with events. There some example on the net, and on the CodeProject website, but i can't succeded to run them properly on VS2008.
If anybody can explain me how to realize this simple drag and drog, I'll be very gratefull
best regards.

If you cannot follow a well laid out tutorial then I suggest changing job/course and trying something less challenging.

Hi,
can any one tell me how to Convert a hexa Decimal value(4363A00E) to decimal(in the format of 123.34567)in C#.Is there any direct function to do this?
Thanks in advance

Why would you want to convert a hex value to a float? Unless it is the hex representation of the internal value of a float?
Or are you just to lazy to tell us what you want to achieve?
Give information, including what you have tried, and you are more likely to get a helpful response.

you really need to see this website. www.lmgtfy.com . It's much more informative

String hexNumber = "4363A00E";
int i = Int32.Parse(hexNumber, System.Globalization.NumberStyles.HexNumber);
Why do you want to display it in decimal? You can't create decimal with an hexa...

Hi,
Thanks for replying so soon. I am doing an application involving serial Port.I am getting data from Serial Port in Hexa decimal format(for eg.436300E).I need to convert that into floating point(eg.123.34).
Thanks

Data from a serial port generaly comes in as a stream of bytes, and are not amenable to conversion to float directly - parse probably wont work.
I assume your data is coming from a data logger or sillyscope or similar? You will have to give more detail on the incomming data stream before anyone can help you much.

Hexidecimal notation usually is always involved with integer values. To convert to a float, you'd need to convert to an integer first and then move into the floating point world.
Your hexidecimal representation, is it fixed point or floating point?

In that case what you need to do is use the BitConverter which will convert a set of bytes into another data type. To get your bytes (hopefully 4 of them) to a float you need to use ToSingle
So you'd have:
byte[] data = ...
float myFloat = BitConverter.ToSingle(data)
ToSingle also takes a second parameter (all of the functions in BitConverter do). The second parameter is the offset in the set of bytes where your float starts. That way if you had a stream you could just read all of the bytes out and then work your way through; rather than copying out 2 or 4 bytes to some other array all the time.
EDIT: You say your getting the data in hex format, I assume your just getting bytes which are usually represented as hex. If you are actually getting a string from the port then you'll need to convert that back into a set of bytes,.

You may use a 'union' see [^]
[System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Explicit)]
struct TestUnion
{
[System.Runtime.InteropServices.FieldOffset(0)]
public UInt32 i;
[System.Runtime.InteropServices.FieldOffset(0)]
public Single s;
}
and then, for instance:
TestUnion tu = new TestUnion();
tu.i = UInt32.Parse("4363A00E", System.Globalization.NumberStyles.HexNumber);
Single s = tu.s;
However it gives 227.625214 as result (are you sure about the expected output?).
