I've looked really hard, but I can't find a '6' button anywhere, so unfortunately I'm only going to be able to vote you a 5. Sorry about that.
Fantastic.

Well well well, first of all I'm not lazy... and by reading your answer, people will thing .Net Framework developer were fool because they made 'break'. Perhaps the programmers they use 'continue' are lazy too.
Now, take an example...you need to iterate an array until you got a value hmm... 9. Now how you gonna do
for (int a=0; a < arrayx.Length; a++)
{
if (arrayx[a] == 9)
break;
}
or
bool foundNine = false;
int index = 0;
while(!foundNine)
{
if (arrayx[index] == 9)
foundNine = true;
index++;
}
I'll always prefer the first one...I dunno about you, it may look you a work of lazy coder.

Perhaps not, but you aren't thinking about proper use of language constructs - hence my original comment.
int index = 0;
while (arrayx[index++] != 9)
{
}That's how you'd do your example - now, you can justify yourself as long as you like but you are promoting a bad practice. Now, let's extend your sample to see why it's bad practice.
bool foundNine = false;
for (int i = 0; i < array.length; i++)
{
if (array[i] == 9)
{
foundNine = true;
break;
}
}
if (foundNine && SomeOtherCondition())
{
DoSomething(array[i]);
}Contrast this with:
int index = 0;
bool foundNine = false;
do
{
if (array[index] == 9)
{
foundNine = true;
}
else
{
index++;
}
} while (!foundNine);
if (foundNine && SomeOtherCondition())
{
DoSomething(array[index]);
}I don't know about you, but this doesn't feel like such a horrible hack.

All I ask is that you've considered the alternatives and given some thought to them - there are few absolute rules in programming, but it is important that you can actually justify why you've used a particular construct.

nope you didnt.
"I cringe whenever I see people use break statements inside for loops because it shows they've just gone for convenience without actually considering what they are trying to do."
"Whenever I see people recommending break or goto statements, I know that they are being lazy or have given no thought to what the proper use of the loop should be."
plus you did unfair, you change the while loop to good one but messed up the for loop
here is mine
bool foundNine = false;
int i = 0
for (; i < array.length; i++)
{
if (array[i] == 9)
{
foundNine = true;
break;
}
}
if (foundNine && SomeOtherCondition())
{
DoSomething(array[i]);
}
still better than while

No it's not. You've now introduced obscurity for maintenance coding. Where's i declared in your loop? Outside - that's where. Your example is now even more confusing, and I'd rip your code apart in a code review if you did that while working for me.
You're not going to convince me that you can come up with a decent reason to ignore the fact that a while loop wouldn't be a better fit here, and it's obvious to me that you aren't willing to consider that your coding practice could possibly be less accurate, so I'm going to break off this discussion now before it becomes he said/she said.

I think it's harder to write maintainable code than to write working code. Most of us on this forum work mostly toward the working code.
..and then move on to the next project. Maintenance of the code wasn't (isn't?) a priority in school, and I made a lot of mistakes before my code became even close to being 'readable', let alone easy to maintain.
Where does one learn such things, except by trial and error?

I've created a new setup project with Visual Studio 2008 inside my solution and added my .EXE files to the setup.
Then I've created to each .EXE a shortcut and moved it to the user's Program Menu. There I'm able to set the Icons property to an external icon.
Problem: The file and path have always to exist. If I move my solution to another computer, I'm always getting an error of missing icon file.
The Icons itself are stored in the Resources of each project inside this solution and connected to the Application Icon property.
Is it possible to use these resource icons or include them into the setup project ?
If yes, let me know how ? If no, let me also know

Can we catch(or overload the event handler) the (Yes, No, Cancel) button click events of Microsoft Excel when the user clicks the Close(X) button on the top right corner of the ms excel workbook? Am basically building an excel automation add-in to ms excel using c#.

Excel isn't written in C#, and you can't just hook into the code like you would with something that you have written yourself. You can hook into native code, you can get the handle of the buttons of the closedialog and send a click-message, but I don't know if it is possible to hook into the WndProc of Excel.
This is not a simple assignment for the weekend!

hey Eddy, thanks for replying. I've been scratching my head since...
Basically, I want to create an xml for every excel sheet the user saves and when he reopens the excel sheet, I am supposed to open the corresponding xml. Thus, I used the WorkbookBeforeClose http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.workbook_events(VS.80).aspx[^]event and my whole aim is achieved if *the user is saving the sheet first and then closing ms excel*
However, the problem is, when he is trying to save the sheet by: Press the Close(X) button and when the pop up which says "Do you want to save changes to filename.xls? 'Yes' 'No' 'Cancel'" shoots up and IF he is choosing 'Yes' here, am not able to achieve the same. The reason being, the WorkbookBeforeClose event is invoked as soon as he presses the Close(X) button on the top right corner of ms excel.
I want to somehow be able to know whether the user has chosen 'Yes' or 'No' from the pop-up. Can I?! If yes, kindly tell me how?!
Regards.

I'm no expert on Excel-interop, but I'm sure that some of those hang round here. In the meantime, there are two interesting events in that same documentation;
- BeforeSave
I guess this one is also fired if the user chooses "Yes", but not if he chooses "Cancel" or "No".
- ShutDown
Signals that the application is about to shut down.
Perhaps you could do the same with a FileSystemWatcher, watching all the XLS-files in the specified directories for updates.
Anyone else any idea's?

Hi.
I saw it somewhere for allocate an icon to a component.
What is the name of it ?
Has it a specific name ? ( Like attribute ! )
[System.Drawing.ToolboxBitmap(typeof(WebCamCapture), "CAMERA.ICO")]
Thank you

how i can use the openfiledialod and savefiledialog the return picture in c#

Uhmm, i don't think I understood your question. What do you mean with "return picture"?

You can configure to only select picture files, but it will still return a file path or a stream, it's up to you to load it as an image, and use it however you like.

If you are asking about to open and save only picture files then you have to add Filter to dialogs of all image file formats like *.jpg, *.gif, *.bmp
|
|
|
|
|
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "PNG|*.png|JPG|*.jpg";
if (ofd.ShowDialog() == DialogResult.OK)
Image img = Image.FromFile(ofd.FileName);
this may help

In my DeviceManager i can see 3xCOM port installed. Only one of them is physical port - 2 other are virtual. When I list them:
string[] portNames = SerialPort.GetPortNames();<br />
<br />
foreach (string port in portNames)<br />
{<br />
listBox1.Items.Add(port);<br />
}<br />
I get: COM1, COM2, COM3. It tells me nothing - only that 3 ports are installed in my computer. Other way is to use WMI. It works perfectly for physical ports.
<br />
SelectQuery query = new SelectQuery("select * from Win32_SerialPort");<br />
<br />
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);<br />
<br />
ManagementObjectCollection collection = searcher.Get();<br />
<br />
foreach (ManagementObject port in collection)<br />
{<br />
listBox2.Items.Add(port["Name"].ToString());<br />
}<br />
That way i get only "Name" (Communication Port) of the physical COM port but no virtual ports are listed.
My question is: How to get property "Name" or any other of the virtual serial ports.
Thanks in advance
ps. Sorry for my bad english :]
