a) examine the eventlog - events there are in chronological order.
b) write to eventlog your own entries.
c) examine registry entries. booting leaves trails in registry. hint: RegQueryInfoKey()
combine methods.

What is the syn. function for _ttoi() to convert a string to a float/double (must compile with ANSI and UNICODE).

wcstod

For a no source code change, use _tcstod, which I think is what the original poster wanted.

I am using CAsyncSocket class in one of my very simple windows application. The problem is that whenever i called the connect function, my program blocks for few seconds. How can i get rid of this blocking problem ??
|

|

you can put your sockets in separate worker threads, or deal with the blocking issue,
put the string into MSDN:
Windows Sockets: Blocking

hi all,
when i used FindFirstFile() i got the file name as ".",for the first
FindNextFile() call i got the name as ".." and for the third i got the correct one..how can i avoid the first two cases..

Use proper wildcards. If you use *.* then it is quite normal you get those two (which are part of the operating system (. is an alias for the current dir, .. is an alias for parent dir)).
if you start putting in too manay features, it no longer remains useful for beginners

You can't exactly, but for stuff other than the root directory of a drive, this will always be the case (just like *n*x systems), so inevitably I have a check for "." or ".." in things dealing with this.
If you only want files and not directories, you can also check the attributes that are present in the results.

You must be saving the result in an array or a buffer. Just omit the first two elements when retrieveing the array.

I have the following code:
CString str("112");
int n = atoi((LPCTSTR) str);
This code works fine under VC++ 6.0, but under eVC++ 3.0 (UNICODE) the code doesn't compile, because the function atoi doesn't support UNICODE.
How can I write the function (convert a CString to a integer and float) so that it works with and without UNICODE?
I need to functions... one to convert a CString to a float and one to convert a CString to a integer!
|
|
|
|
|
use _ttoi which is the TCHAR version
int n = _ttoi((LPCTSTR) str);
|
|
|
|
|
And what kind of function is to convert a string (CString) to a float?
|
|
|
|
|
Like any of the A functions atoi() never ever supports unicode (same goes for itoa()). Use either _wtoi or _ttoi.

int whatever = _ttoi((LPCTSTR)str);
or, if you want explicit support
if(bUnicode)
whatever = _wtoi((LPCWSTR)str);
else
whatever = atoi((LPCSTR)str);

Hello,
I have a dumb question.. I have an app that runs perfectly fine in Debug mode.. no problems what so ever, but when I try to run it in release build it errors when I first fire it up with a "The instruction at "0x0040cf93" referenced memory at "0x0010ab000". The memory could not be "read"." How does someone go about finding out why this is happening only in the release build?? Kinda weird.
Thanks!
Rob

Hello
Anyone knows how we can change the current XP theme via code?
I am looking for a reverse version of GetCurrentThemeName.
Or is it enough to modify the registry (assuming thats where the data is
stored) and then send a WM_SETTINGCHANGE to all top level windows?
Regards and thanks,
Nish

 Hi how are you,
Do you know how I could plot some histograms in C++.
This whole thing should look something like that:
"There are 4 values for each #
Histogram starts at 10.000 with a step size of 5.000.
10.000 : ########
15.000 : #############
20.000 : #######
25.000 : #########################
30.000 : ###############
There are 15 inputs not in the range 10 to 35.
Can you tell me how I could proceed to plot a histogram in C++ like this. It should involve
• A function to read the input values and keep the count in an array.
• A function to obtain the maximum value in a given array.
• A function to calculate an integer division, but with rounding up.
• A function to plot the histogram.
• The main function to drive the whole program.
If you have any suggestions or some good links to any website that might concentrate on histograms, would be of great
help for me.
Thanks

Go to http://root.cern.ch
and download the Root package. This includes an C++ Interpreter and many visualization
classes in C++. Including 1,2,3-D Histograms, Fitting algorithms 3D-Functions and much more.
e.g The C++ Script: http://root.cern.ch/root/html/examples/hsum.C.html
produces this Histogram

Hope this helps.

This sounds too much like a school assigment, please start writing code, and we'll be really happy to help you with specific questions!
I may sound harsh, but that's the way it is. but I will give you a hint, not a programming one, but a generic one :
When facing a problem like this, first, start by figuring out how you'd do this manually, write things down using real words and you find that the answer is really simple and that "translating" it to any programming language is easy!.
Max.
