hi i have a .exe file which load a xml file....but the xml file mustn't be loaded into the exe!? the exe dont work with the xml on the computer where no framework is installed;-(

First of all, any solution for creating an exe without the framework is a hack. Second, this product is obviously crap, because it's looking for a dll it needs in the wrong place. I'd give it up.

No chance in hell. I wouldn't trust any framework like that, like I said, it's a hack.

Hi, I used the tutor from microsoft to get messages from my IR Control (link). The code works fine, but when the window loses focus, it doesn't work anymore.
I need this code to work also when the program doesn't have focus (global hook?).
Thanks in advance.

From the little that I've seen about this, the remote works by using keyboard emulation. About half of the remote's keys are sent to the application using WM_INPUT and WM_KEYDOWN messages. This makes it easy to use, but when the focus changes, the "keystrokes" are now going to another application.
This presents a problem. Since the message from the remote are exactly like normal keyboard messages, there's no way to tell them apart. You COULD put together a low level keyboard hook, but there's no way to tell if the keystrokes you're seeing are coming from the real keyboard or from the remote.

Thanks, I'll go find some stuff on keyboard hooks then.

I use following code snip to validate @ sign, but it works with US keyboard only.
switch(e.KeyData)
{
case Keys.D2 | Keys.Shift: // @
It seems that System.Windows.Forms.Keys enumeration did not specified @ sign. How can I know I receive @ sign in KeyEventArgs?
TIA,
Frank

Have you checked the integer value of the keycode? My guess is that value will be unique to the @ symbol.

The value is 50, which is the ASCII value of 2. The KeyData is Keys.D2 | Keys.Shift. Actually, the ASCII value of @ is 64. Any idea? TIA.

Here is a quote from one of Nish's articles using MFC
Using PreTranslateMessage to handle dialog keystrokes
Very often you hear questions from novice programmers asking
how they can trap keystrokes in a dialog based application.
Presumably they tried to handle WM_KEYDOWN/WM_KEYUP unsuccessfully.
The whole problem is that in a dialog based application the focus
is always on one of the child controls and not on the main dialog
window. So what do you need to do? You need to override
PreTranslateMessage.
How do you accomplish this using C#?

|

There is a SystemKey event. Also, a dialog in C# has a property called 'key preview', which I believe means the dialog gets the keyboard message before the control does.

In your form code, override ProcessCmdKey method.

I don't know if anyone else has had this problem with the AxWebBrowser. I have a AxWebBrowser on a form and it works great when I bring up the form for the first time. When I open the form for the second time however the AxWebBrowser control seems to become unattached from the form. It still shows up but it is just floating by itself.
Do I need to use the dispose method for the AxWebBrowser when I close the form? If so how do I create the AxWebBrowser during runtime? I tried to do this but I'm doing something wrong because the Browser doesn't show up. I tried this code in the form's load event.
AxSHDocVw.AxWebBrowser WebBrowser = new AxSHDocVw.AxWebBrowser();<br />
WebBrowser.Location = new System.Drawing.Point(8, 8);<br />
WebBrowser.Size = new System.Drawing.Size(100,100);

I need to know which could be the best way to communicate two or more applications that could be in oneself PC or in different machines. Which is more efficient, the use of threads, services or another thing.
Thank you anyway.

There is no single best way, largely because the definition of "best" changes from one application to another. In order for someone to give you good advice here, you should describe as much as you can about:
- frequency of communication
- approximate size of the data (both directions)
- all different connection options between the computers
- whether other software, such as firewalls, are a consideration
- the way a user will interact with your software
- anything else that may impact the meaning of "best way to communicate" for the software under consideration

The frequency of the communications will be high. I have four modules, and the communication of a module to the rest (the other ones PCs ) will be unidirectional, but I need that this communication be fast and constantly, the size of the information is small. In some cases the communication will be bidirectional.
Where I can find information related with this topic.

Based on this small bit of information, the closest widely-known model would be that used by MMORPGs (massively multi-player online role-playing games). They commonly use UDP as a primary element of their communications. This might be overkill for you, though. Your definition of "fast and constantly" may be less demanding.

Hi,
I measured the time the following code executes on a 64-bit computer:
for(int x = 0; x < 100000000; x++)
{
double a = 1234.56789 * 1234.56789;
double b = 12345.6789 * 12345.6789;
double c = a / b;
}
Testing cases:
1. code compiled in .NET 2003 (32-bit)
2. code compiled in .NET 2005 (x86; 32-bit)
3. code compiled in .NET 2005 (x64; 64-bit)
Results:
case 1 was the fastest
case 2 was a little bit slower than case 1
case 3 was around 5.5 times slower than case 2
I expected case 3 is the fastest (then case 2 and, finally, case 1).
Does anyone know why that happens?
Thank you,
|

Case 3's being so slow is weird, but since all x86 processors do floating point math using an 80bit denormalized value internally there shouldn't be any architectural level difference in the performance. At a guess, 64bit machines are still rare enough to be a relatively low priority for the optimizers.

I'm just guessing, but aren't 32 bit integers slower on 64 bit machines? Did you try using a 'long' on the for loop, instead of an 'int'?
