I'd need to see the code for Class1 - sorry if I wasn't clear. As someone says below, it could be a static constructor causing the issue - but without seeing the code for the class it's hard to guess. ___________________________________________ .\\axxx (That's an 'M')

Hi There, You do that by using the unsafe keyword, pointers are not safe type in c#, and as you know c# uses managed code which uses garbage collector, but in un-managed code the garbage collector cant interfear, pointers in c# requires writing unmanaged code, therefore you have to use the unsafe keyword.

Only one of the two is correct, unless data is declared as an array (i.e., for instance char data[8];).

then assign in to a byte array and then if you need that as an object array loop through the byte array and pass each one to an object array. byte[] ba = BitConverter.GetBytes(write_number); object[] oa = new object[ba.Length]; for(int i = 0; i < oa.length; i++) oa[i] = ba[i]; Life goes very fast. Tomorrow, today is already yesterday.

It's converting a float from little-endian form (presuming this code is running on an x86/x64 PC) to big-endian. Let me add comments to your code: // Declare a union so we can easily access the bytes of a float typedef union ieee_754_single_precision { BYTE bytes[FLOAT_BYTES]; // Let's hope FLOAT_BYTES == sizeof(float) float value; IEEE_SBITS bits; // Don't know what this is... } SIEEE_754; void cHARTTransmitter::Float2IEEE(float fDecimalNum, BYTE *pbIEEE) { SIEEE_754 local; // Set up an index to iterate through the bytes array in local - see my later comment. short j = FLOAT_BYTES - 1; // Assign the float to the union. The bytes making up the float are now available though local.bytes local.value = fDecimalNum; // Now transfer the bytes from local to pbIEEE, reversing their order // as we do so. It might make it clearer if we replace "j--" by "(FLOAT_BYTES-1)-i" // If we look at i and j, we see that // // pbIEEE[0] = local.bytes[3]; // pbIEEE[1] = local.bytes[2]; // pbIEEE[2] = local.bytes[1]; // pbIEEE[3] = local.bytes[0]; // // (BTW - what compiler is this that doesn't require i to be declared?!) for (i = 0 ; i < FLOAT_BYTES; i++) { pbIEEE[i] = local.bytes[j--]; } } Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

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? My current favourite word is: Delicious! -SK Genius Game Programming articles start -here[^]-

is it possible to replace 'switch' by 'while/for' , and 'case' by 'if'? thanks

I was merely demonstrating that (by using the C pre-processor) one could use goto without actually seeing the goto keyword. It was a joke.

Actually break; cause the switch to exit and continue with the codoe afterwards. Leaving it and not writing anything, but simply adding other case will automatically cause the switch to move on and execute all code until the next break; Thus if you have somethng like this: switch(number) case 1: //do stuff break; case 2: //do stuff or not case 3: // do more stuff break; case 4: //do stuff break; the program will do the exact same for 2 and 3. If you don't want it to do anything different for 2, you might as well leave that case empty, so it immediately goes to the next code before the break;

Hi, split the problem in a couple of smaller ones. There are at least two parts: 1. locate the "word" that contains the number 2. translate that word to a numeric value 1. depends on what you do know about the pattern in the string. e.g. if the number is always at the end, find the last space, get the substring behind it. if there is exactly one word plus a space in front, find that first space and look for a possible space after the number too. 2. is easy with int.Parse or int.TryParse If you were really lazy (I wouldn't dare to assume that), split the entire string in words based on a space, then foreach "word" do a TryParse until one succeeds. And now you are on your own I guess. :) Luc Pattyn [Forum Guidelines] [My Articles] - before you ask a question here, search CodeProject, then Google - the quality and detail of your question reflects on the effectiveness of the help you are likely to get - use the code block button (PRE tags) to preserve formatting when showing multi-line code snippets

You can't drop through a case, but you could always include it inside a loop, so each case is executed until the value is outside of the maximum. ___________________________________________ .\\axxx (That's an 'M')

Well that would tend to indicate that the device is returning the wrong information. Log all data to a text file and then take a look at the file to see if there is any pattern to the bad values. Your options are to fix the device, or if that is not possible to write code to ignore the bad values. Until you know a lot more about the data that is coming from the device you can't begin to parse it reliably. Alan.

GetPrivateProfileString asks for a default value. It will return this value if the section or the named value doesn't exist :) I are troll :)

Because that data is one of the codes that represent the value NaN. Try for example { 0, 0, 128, 63 }. Despite everything, the person most likely to be fooling you next is yourself.
