Can anyone here recommend a quality free, easy-to-use CHM editor???

I don't believe that you can edit with the application, but to create CHM files you can use HTML Workshop from Microsoft.

Yeah - I've tried that one. It's not very easy to use.
There must be another free CHM editor that is easier to use.
|
|
|
|

It is from Microsoft. What do you expect? 
I am not aware of any other free CHM editors. You would have to google the subject.

Hey everyone,
I've got a short question whichs answer hopefully is as short too
I'd like to "concatenate" two integer values without casting them to strings. Let me illustrate what I want to do by showing you a code snippet:
int x = 1, y = 2;
string xyStr = x.ToString() + y.ToString();
int xy = int.Parse(xyStr);
And now the question:
Does someone know a possibilty to do this without casting the values to a string first?
Thank you in advance,
mik

Yep
xy = (x * 10 ^ z) + y
You need to find out how many to-the-power (z) you will need from y.
Edit: not x ^ z but x * 10 ^ z

And that can be done by counting the number of significant digits (places) after or before the decimal (depending on which way you're going).

I think it should be possible with some bitshifting, but this is a simple solution:
public int ConcatInts(int x, int y)
{
return (x * ((int)Math.Pow(10, NumDecs(y)))) + y;
}
public int NumDecs(int x)
{
int result = 1;
while (x >= 10)
{
x /= 10;
result++;
}
return result;
}
or, by using the logarithm with base 10:
public int ConcatInts(int x, int y)
{
return x * (int)(Math.Pow(10, (int)Math.Log10(y)+1)) + y;
}
Some time comparisons, with the string method being the slowest (100%, but might be optimized a bit using a StringBuilder):
Log: 31,62%
Loop: 30,57%
for 100000000 runs each.

That's pretty easy, actually even easier than I first though:
int x = 1, y = 2;
int m = 10;
while (m <= y) m *= 10;
int xy = x * m + y;
Despite everything, the person most likely to be fooling you next is yourself.

Should have been a Friday programming quiz.

hy everyone!
does anyone of you know which encoding has to be used to handle files in windows-1252 correctly via streaming, so no characters are lost or replaced by non printable signs?
thanks!
stephan.

Stephan,
You can get the 1252 encoder like this.
Encoding coder = Encoding.GetEncoding(1252);

I like to know how much memory is available in the system before I allocate any memory block.
Is there any class or way to get the current memory information from the system.
Thanks you for your help.
|
|
|
|
|
It could change between the time you check and the time you try to allocate anyway. Just try the allocation and catch the exception if any.
|
|
|
|

Allocate the minimum amount of memory necessary for the given task.
Also, in c# a memory allocation should not fail unless it exceeds the allowable limit set by the framework for the application, the slowness will be OS based thrashing from VM.

Thanks for your suggession.
Is there any way to know the amount of memory available programmatically even it might change from time to time. Just like taskbar, I like to know the snapshop of memory in any instance.
Thank you again

Is there a way PROGRAMATICALLY( by code) to get memory information just like taskbar shows us.
|

Thank you for pointing me to the right API. I looked at the API's but I overlooked this function.

Do you know how much memory you need to allocate or are you allocating "as much as you can" for some reason?
If the former (you know what you need) - look at the System.Runtime.MemoryFailPoint in the later .NET versions. It was created to solve that need.
If the latter (you don't) - consider rethinking your app. Seriously, stuff that does like that is a nuisance. Microsoft SQL Server and Exchange Server are two examples (using default settings). That's why they don't play well together in the same machine (without reconfiguring - and as Exchange requires direct Active Directory object property editing for that, it's even more of a nuisance). They keep fooling each others cache allocation strategies, and you end up with system requiring frequent restarts due to memory fragmentation.
