I think you have missed my point!
An array in .NET is nothing like C++ or VB.
It is an Array object, a collection, NOT a series of memory locations initialised as a standard array.
I would suggest you do some more reading regarding collections, it is pretty important.
But to give you a head start, when you create an array here, you are actually creating a list of reference variables, and not that actual objects themselves, so, you will still need to call new on each location!
For example
<br />
cInput[] bInputs;<br />
bInputs = new cInput[2];<br />
<br />
for(int i = 0; i < bInputs.Length; i++)<br />
{<br />
bInputs[i] = new cInput();<br />
bInputs[i].m_SetState(true); <br />
}<br />
I would also suggest hwever, that if you are using .NET 2.0 or newer, look at and learn generics (again, look at the collections)

Hi,
I need to retrieve local settings (country) of windows installation.
have any ideas?
thanx
|
|
|
|
|
Use the CultureInfo object in the System.Globalization namespace. It contains the default country settings. You can also use this class to set country settings for your application if you wish...

Hello,
I am trying to run an .exe from my windows application. So I have this screen that when loaded, it creates a Process object and runs an .exe, captures the log file and writes it on a TextBox on the UI. The windows Form also has a [Stop] Button where it will terminate the Process when pressed.
My problem is that as I run the .exe, the main application hangs that it's almost impossible to press the [Stop] button. In the application though, I can still see the log file being captured and printed on the text box, but the [Stop] button just won't click.
I tried setting the Process' Priority to BelowNormal but the problem was not solved.
Any suggestions?
Thanks!

Wild guess:
You have to invoke the method which does this!
All the best,

You'd have to confirm with your code, but my wild-ass guess is that you're monitoring the process's output on your UI thread. Hence, it's not processing window messages, so it never sees the click on the Stop button.
You need to move the monitoring to a different thread, and use Invoke/BeginInvoke to send the text back to the UI thread to update the text box. .NET Framework 2.0 will throw exceptions if you try to modify a Windows Forms control from the wrong thread, when debugging; .NET Framework 1.x will not, but it's still an error.

Hi ,
How can I convert struct like this to array byte
public struct Message
{
public byte id;
public int value1;
public int value2;
public byte chkSum;
}
Not in this way :
public void converter()
{
Message message;
message.id = 1;
message.value1 = int.MaxValue ;
message.value2 = int.MaxValue ;
message.chkSum = (byte)(message.id +
message.value1 +
message.value2) ;
byte [] dataToSend = new byte [10];
dataToSend[0] = message.id ;
byte [] dataToInsert = BitConverter.GetBytes (message.value1 );
Array.Copy(dataToInsert, 0, dataToSend, 1, dataToInsert.Length);
dataToInsert = BitConverter.GetBytes(message.value1);
Array.Copy(dataToInsert, 0, dataToSend, 5, dataToInsert.Length);
dataToSend[9] = message.chkSum ;
}
thank you

Perhaps one way is to use a pointer ? You can set up a struct so that you specify how the bytes are laid out.

If you don't want that, what do you want then? What should the result be?

You can use MAPI, but I don't think you can send an attachment with a mailto

Hello,
In .Net < 2.0 you have to use System.Management functionalities.
ArrayList drives = new ArrayList();
using(ManagementObjectSearcher DriveSearch = new ManagementObjectSearcher(new SelectQuery("Select * from Win32_LogicalDisk")))
{
using(ManagementObjectCollection moDriveCollection = DriveSearch.Get())
{
foreach(ManagementObject mo in moDriveCollection)
{
LogicalDriveInfo driveinfo = new LogicalDriveInfo(mo);
if(this[driveinfo.Name] == null)
drives.Add(driveinfo);
mo.Dispose();
}
}
}
For .Net >= 2.0 you could use DriveInfo.GetDrives()[^]
All the best,
Martin

Does anyone have a simple example or steps on how to print a datagrid with paging and sorting? I would like to attach the function to a button control on the form and then once clicked send the entire datagrid with whole data to the printer

i use datagrid and i make changes and add new rows. and i want to save all of this changes and new rows with pressing a button, or without pressing a button when i make changes it will be save, may be it can be save when going another row

YOu don't say where the data comes from. Basically, if it's a database, you need to grab the new data and store it there, just like you had to pull the old data out.
