Hi Guys,
Is there any way to change the tab orders for a controls programmatically.
|
|
|
|
|
SetWindowPos
Use wndTop for the first control, and the previous window for the remaining.

I think you could try this:
1- Destroy all the controls you want to set the tab-order of.
2- Create them again in the order in which you would like the tab-order.
this is this.

NO!!!!!!!!!!!!!!!! 
Use SetWindowPos to change the Z-Order - TAB order int he dialog merely follows the controls' Z-Order.

You have probably tested this technique, and I haven't tested my ideas, so I guess you are right.
Thanks for the correction.
this is this.

Yes, it works well. When you create a control on the fly, you can also use SetWindowPos to 'insert' it into a specific tab order.
You method will work, it is just overkill.

Yes, I also tested my idea yesterday, and it works. But as you said, it is just overkill. SetWindowPos() is much easier and simpler.

Hi,
I want to compare two character arrays containing binary values.
For e.g. if m_Effects array contains 0001, string comparison does not return 0 even if binEffects contains binary equivalent of 1. Even if I do byte by byte comparison same problem occurs.
What does _ltoa exactly perform?
//---------------------------------------------------------------------
for(int i=0; i <16; i++)
{
_ltoa(i, binEffects, 2);
if(strcmp((char *)binEffects, (char *)m_Effects) == 0)
return i;
}
//---------------------------------------------------------------------
Thanks,
Kranti

u can directly use strcmp/memcmp to comapre two integer array
nave
|
|
|
|

when I check the values stored in both of the arrays, something like the following is observed ...
binEffects[3] = '0'
binEffects[2] = '0'
binEffects[1] = ''
binEffects[0] = '1'
and the source array contains ...
m_Effects[0] = '0'
m_Effects[1] = '0'
m_Effects[2] = '0'
m_Effects[3] = '1'
Even if i use memcmp(), it returns -1 if this example is concerned.
Hence, i've a doubt regarding _ltoa function since it sets the values in binEffects.

Did you read my post ?
That is a standard behaviour. If you want to convert an integer (let's say 3) in binary string, you won't have the zeros in front of the number, that sounds logical isn't ?
So, when you convert 3 into a binary string, it's logical that you get '11' and not '0011' (how can the compiler knows that you want 2 zeros at the begining of the string). The same when you convert 1 into a string, you will get '1'.

I think you want to convert a binary string into its value ? Right ?
Maybe you can write a simple function to do that:
int BoolStringToVal(char* szString)<br />
{<br />
int Value = 0;<br />
for (int Index=strlen(szString)-1; Index>=0; Index--)<br />
{<br />
int BinValue = 1 << (Index - strlen(szString) + 1 );<br />
if (szString[Index])<br />
Value += BinValue ;<br />
}<br />
<br />
return Value;<br />
}
So, what it does is look for each char in the string and if this char is 1 then we add its corresponding value to the total value. The code has not been tested so I'm not sure if this will work, but you got the principle.

It would be better and faster to use the reverse function of _ltoa -> strtol. And now your code looks like that:
char* e;<br />
int iEffects = strtol((const char *)m_Effects,&e,2);<br />
for(int i=0; i <16; i++)<br />
{<br />
if(i==iEffects)<br />
return i;<br />
}

hey,
it worked! 
Thanks a lot!

How do I delete a file so that it goes to recycle bin, the following code doesnt seem to work?
<br />
static void delete_file()<br />
{<br />
SHFILEOPSTRUCT shf;<br />
int ret = 0;<br />
shf.wFunc = FO_DELETE;<br />
shf.pFrom = filename;<br />
shf.fFlags = FOF_ALLOWUNDO;<br />
<br />
<br />
if(0 != (ret = SHFileOperation(&shf)) {<br />
printf("could'nt delete \"%s\" to recycle bin (err=%d/%ld)\n", filename, ret, GetLastError());<br />
}<br />
}<br />
<br />
thanks!

pFrom must be double terminated.
pTo must be set to NULL if not used.
Paul DiLascia has a good article on using the Recycle Bin from
MSDN April 2001.

This works.
char file[MAXPATH];<br />
int ok;<br />
int l;<br />
strncopy(file,filetodelete,sizeof(file));<br />
shfop.hwnd = GetDesktopWindow();<br />
shfop.wFunc = FO_DELETE;<br />
shfop.pFrom = file; l = strlen(shfop.pFrom);<br />
if((l+2)<sizeof(file)) file[l] = file[l+1] = 0;<br />
shfop.pTo = shfop.pFrom;<br />
shfop.fFlags = FOF_ALLOWUNDO|FOF_SILENT|FOF_NOERRORUI;<br />
shfop.fAnyOperationsAborted = 0;<br />
shfop.hNameMappings = 0;<br />
shfop.lpszProgressTitle = shfop.pFrom;<br />
<br />
ok = SHFileOperation(&shfop);<br />
ok = (ok==0) && !shfop.fAnyOperationsAborted;

Hi All,
Can anyone tell me how to programmatically search for a file in a specific directory?
Thanks and Regards,
Anil

i mean just to find out if the file exists or not...

The most simple version.
WIN32_FIND_DATA fd;<br />
HANDLE hf = FindFirstFile(fullfilename,&fd);<br />
if(hf==INVALID_HANDLE_VALUE) return 0;<br />
FindClose(hf);<br />
return (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY);

Sorry i forgot the neg (!) at the return line.

Hello,
Actually, am getting data from the machine as 0x03 0x10 0x82 0x10..... and length of the buffer is varying, as Length:108 or 256 or....so how to proceed further to parse the data and store the data in an array. do we have any Active X control for parsing the data?
