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 />
}

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.

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);

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?

how an activeX could help you there ???
well, you reposted your question, but you don't really say much once again.

this doesn't mean anything (or it could mean everything) depending on haw you want to interpret those bytes...
that's why i asked you the format of the datas supposed to be received...
please precise the type on how you receive those data, how you want to change them, tell also if there are some important thing to read from the stream...
help us or we won't be able to help you !!

I would like to have the data in (Radius, Angle) i,e in polar coordinates, thats all the data what i could read from machine, i dont even have the header information also.
I think, you got my problem...

Use CArray for storing the data
nave
|
|

|

I hope to understand you right. The aim is to convert a variable length block of input data with hexadecimal numbers into an array to integers. If it' true try this:
<br />
void ParseBlock(const char* lp)<br />
{<br />
CArray<int,int> a;<br />
unsigned int i,n;<br />
int result;<br />
for(i=0;lp[i];i+=n)<br />
{<br />
if(!(n=ParseOneValue(lp+i,result)) break;<br />
a.Add( result );<br />
}<br />
}<br />
<br />
unsigned int ParseOneValue(const char* lp,int& result)<br />
{<br />
unsigned int i;<br />
char* e;<br />
while(lp[i] && !isdigit(lp[i])) ++i;
if(!lp[i]) return 0;<br />
if((lp[i]!='0')||(lp[i]!='x'))
{<br />
result = strtol(lp+i,&e,10);<br />
return e-lp;<br />
}<br />
i += 2;<br />
result = strtol(lp+i,&e,16);<br />
return e-lp;<br />
}
sorry the html won't take the tabs.

in my project, i have a login dialog which opens to a MDI form if the username is valid. how can i call an MDI form from the dialogs button click
-- modified at 4:25 Wednesday 1st March, 2006
Using App wizard i chose to create a MDI application. In such cases when we run the program the MDI will run first. But i want to insert a dialog eg a login dialog such that when we run the project the dialog should be displayed first. And on the button(which is placed in the dialog) click the MDI interface should open up. pls give a solution

You don't. The dialog is displayed when the applicaton is first launched, but before the main frame has been created.

Can you tell us more about the circumstances you want to do that. A short code extract would help. Nobody wants to steal anything from you but everybody wants to learn. Therefore tell us more detailed what you want to do.

MFC is so full of capabilities that I am a bit confused in the documentation and help files and cannot find the solution.
The problem:
I have a simple CDialog based app window with an ActiveX control in it. This ActiveX control has a feature that I do not need at all: it makes the dialog box jump in the foreground sometimes. Even if I hide the window (ShowWinow(SW_HIDE)), my app steals the input focus. It is normal behaviour for that ActiveX control and I do not want (and can't) modify the ActiveX control.
But I want to make my app "focusless" - that means if it receives some message to activate or jump foreground or capture keyboard and mouse focus, it should not respond. Have tried OnActivate, OnActivateApp, OnNcActivate, OnSetFocus, but these handlers are triggered AFTER the actual event and this does not work for me. I even agree to have this window to be invisible all the time (or maybe you know how to get ActiveX work without any window at all? , it just needs to be silent in the background until it does what it has to do and then exits.
Any ideas?
Thanks (at least for reading this)
