Hey guys , I vaguely remember an API like GetFilePath, that gives you the directory path of a file when you pass the complete file path. like

c:\windows\temp.txt ------>> c:\windows\

You remember that one? And there were also many functions like that to process the "\" "/" like that and to get root folder and many more things. damn nothing strikes for me now. I stronly remember I found them in MSDN, but couldn't spot any of them now. Please help!

I tried a hundred time "Shell" + api + path and all combination, I got all craps. The worst crap was the page that took me to "Shell("mspaint.exe")" .. A vb function just like createProcess. OMG | :OMG:

VB!!

Anyway I'm so happy I've found the exact page in MSDN Jig | [Dance]

to you!

Yup, I was just trying to spot this guy, found and used it here[^].

Btw David, I have a simple question related to above, If you want to clear a char buffer[] (stack allocated) , what's the proper way?
like :

char szTemp[256];

<br />
strcpy(szTemp,"");<br />
*szTemp = 0;<br />
ZeroMemory(..)<br />
Memset(..)<br />
*szTemp = NULL;<br />

I would use:

char szTemp[256] = { '\0' };

for initialization, and then memset() later on to clear its contents.

As for now, I have only discovered ExtTextOut(), to which I must provide x,y coordinates for starting to write at, and which doesn`t automatically add a scrollbar when reached the end of the screen.
So, did any of you find or know a better solution to this ?

It sounds like you should use a rich text control. If you are using MFC, you can use CRichEditCtrl.

Hi,
If an application has more than one top level windows,
how can I determine which is the main window.

Thanks!

Conversion Problem

Andy20214-Sep-07 4:47

14-Sep-07 4:47

I receive a 20 word message and two words of this message define a floating value;

unsigned short message [20]; // Message buffer

e.g. message [2] and message[3] define a float with the mantissa in the lower byte of message[3].

Could I get the floating value by doing this:-

buffer[0] = message[2];
buffer[1] = message[3];
union
{
float data;
unsigned short buff[2];
}convert;

float val = convert.data;

Or what is the best way to get this 32 bit embedded floating point value.

Andy.

Will two unsigned shorts hold both parts of a float? Since a float is four bytes, perhaps you should use four unsigned shorts.

Thanks David. The code below seems to work OK.

But I am sure they must be a better way to get the result!

unsigned short w1 = 0xc3f5;    // The float is 3.14<br />
unsigned short w2 = 0x4840;<br />
union<br />
{<br />
	float data;<br />
	unsigned short buff[2];<br />
	BYTE floating[4];<br />
}convert;<br />
<br />
convert.floating[0] = (BYTE)(w1/256);		// This gives val = 3.1400001<br />
convert.floating[1] = (BYTE)(w1 & 0x00FF);<br />
convert.floating[2] = (BYTE)(w2/256);<br />
convert.floating[3] = (BYTE)(w2 & 0x00FF);<br />
<br />
//convert.buff[1] = w1;				// This gives val = -490.56445<br />
//convert.buff[0] = w2;<br />
<br />
float val = convert.data;

Perhaps, it is possible, that you wrong the order of

convert.buff[0] = message[2];
convert.buff[1] = message[3];

it can be also

convert.buff[<code>1</code>] = message[2];
convert.buff[<code>0</code>] = message[3];

check this looking to the memory-watcher of VS during DEBUG.

(float usually are 4 bytes, unsigned short can be 2 bytes, elseway DavidCrow gave you a good tip)

Something like that would work if you used the fixes I made in your quote. However, it would be easier to just use

float result = *(reinterpret_cast<float *>(message + 2);

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
