Hi Vladimir Afanasyev,
I read your article .NET - Diving into System Programming.It is really intresting.You had mention some links in order to gain the Intial knowledge of System found all three of the articles to be very informative. I am working on a little project that requires listing all the drivers for a certain device (much like the device manager in windows does) but I have been unable to accomplish it. Can you point me to a resource that explains this or give a brief explanation of how you could do it ? You mentioned Some of msdn but it does not work

Hello,
VS 2008
I have the following code in my timer control
<br />
private void tmrVibrate_Tick(object sender, EventArgs e)<br />
{<br />
vibrateAlert = new Led();<br />
vibrateAlert.SetLedStatus(1, Led.LedState.On);<br />
Debug.WriteLine("Vibrating");<br />
Thread.Sleep(1000);<br />
vibrateAlert.SetLedStatus(1, Led.LedState.Off);<br />
}<br />
I have 2 buttons start and stop. Start will enable the timer and stop will disable the timer.
The problem was that the PDA would continuely vibrate. So I put it in the timer event and set the interval for 2 seconds. Then in the timer event I sleep for 1 second. This will vibrate it for 1 second then switch it off and do this every 2 seconds.
The problem now is, that the UI will freeze during the pause of 1 second.
Is there a better way to do this?
Many thanks for any advice,

You will need to do it in a background thread.

Hello,
I solved the problem using the code below and setting the boolean flag in the timer tick event. However, as the timer is enabled in a thread that is not the UI thread, when I set the timer to enabled to true, the timer doesn't start. I was thinking of invoking the timer. However, the timer doesn't have that property.
private int OnIncomingCall(int _callID, string _caller)<br />
{<br />
callID = _callID;<br />
caller = _caller; <br />
<br />
if (this.btnAnswer.InvokeRequired)<br />
{<br />
this.btnAnswer.Invoke(new EventHandler(UpdateAnswerButton));<br />
}<br />
<br />
if (this.lblCallStatus.InvokeRequired)<br />
{<br />
this.lblCallStatus.Invoke(new EventHandler(DisplayCaller));<br />
}<br />
this.tmrVibrate.Enabled = true;
<br />
drvAnswerCall(_callID, 180);
<br />
return 1;<br />
}
static Boolean ledStatus = true;
private void tmrVibrate_Tick(object sender, EventArgs e)<br />
{<br />
if (ledStatus == true)<br />
{<br />
vibrateAlert.SetLedStatus(1, Led.LedState.On);<br />
ledStatus = false;<br />
}<br />
else<br />
{<br />
vibrateAlert.SetLedStatus(1, Led.LedState.Off);<br />
ledStatus = true;<br />
}<br />
}
Many thanks for any more suggestions,

I can go from an IP to a byte array like this...
byte[] IPBytes = IP.GetAddressBytes();
How do I go back without this horrific mess?
byte[] ip = {127, 0, 0, 1};
IPaddress addr;
string str_ip = ip[0].ToString() + "." + ip[1].ToString() + "." + ip[2].ToString()
+ "." + ip[3].ToString();
addr = IPAddress.Parse(str_ip);
|
|
|
|
|
Just call a constructor of IPAddress class which accepts byte array.
Simple, isn't is? The only thing you need to do is read documentation

There I go trying to over complicate things. I did look through the documentation but I was to busy looking for a way to convert to look at the IPAddress Constructor.

|
|
|
Create a new instance of System.Net.IPAddress class with System.Net.IPAddress.IPAddress(byte[]) constructor.

hy everyone!
I do have a problem:
I insert a picture in an application and try to fetch it again with my tool. the strange thing is although i insert 300x300 dpi pics when fetching they are 299x299 dpi.
after fetching they should be converted to a pdf, but it doesn't accept the 299x299 dpi, but it works fine with 300x300 dpi. (it throws an error it can't handle the format because it is unknown)
is there a chance to check this and to correct it to 300 dpi?
to change it to 300 dpi hardcoded isn't a good idea because there could be 600x600 dpi pics as well etc.
but i wonder, where this 1 dpi was lost and why!
anyone of you a clue?
thanks!
stephan.

You can check/set the DPI within a Graphics object, but I am not sure how you process the image.

How should I abort a running procedure if it takes longer than 10 seconds?
|
|
|
|
|
By setting a 10 second timer and then changing a flag or something. What are you aborting ? I assume a thread.

Since this is in the C# forum I'm guessing you actually mean method rather than procedure. If you do mean procedure (as in a stored procedure) then you should proceed to the SQL Server forum and ask there.
You can run the method in another thread and WaitFor it to return. When you WaitFor it you can set a time out.

I am trying to call a method of a web service & I want the request to be aborted if the web service takes longer than 10 seconds to answer!
|
|
|
|
|
If you are using a SoapHttpClientProtocol - derived class to invoke the web service you can set the Timeout property of it to 10 seconds.
|
|

I'm using MSXML2.XMLHttpClass. & it doesn't have a timeout attribute

Friends I want to do the following things in a function.
Forms.frmFIR fr = new uHTMCM.Forms.frmFIR();
fr.show();
where frmFIR is the form name and uHTMCM is the namespace of the project.
what I want is to send the form name and namespace name in that function(suppose the function name is frmshow(takes two parameter)) and do the above two lines in that function. Can any1 help???
|

Saiyed Alam,
You dont need to pass anything to the constructor, just add the below lines in the frmFIR, they will give you the details you want.
Class name: System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name;
Namespace name: System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Namespace;
MSDN[^]
Regards,
Gareth.

a) if the form is in the same assembly of your method
Assembly asm = Assembly.GetExecutingAssembly();
Form frmTemp = asm.CreateInstance(Your_Namespace + "." + Your_Form_Name);
frmTemp.Show();
b) if the form to be called in from some other assembly
Assembly asm = Assembly.LoadFrom(AssemblyPath);
Form frmTemp = asm.CreateInstance(Your_Namespace + "." + Your_Form_Name);
frmTemp.Show();
Hope this helps
