Hello,
I get
GetAgencyListCompleted EventHandler and
GetAgencyListCompletedEventArg EventArguments delegations from a WebService to check the EventHandler result. The result property (object) of the eventhandler will bring the list of items that what I am looking for.
However, I get implicitly conversion error message in the code below. How can solve the problem?. If you know the solution, would you please show me how to do it?
Thanks.
ProntoWS.GetAgencyListCompleted += new EventHandler <PSSaleWS.GetAgencyListCompletedEventArgs>(Proxy_AgencyInfoCompleted);
void Proxy_AgencyInfoCompleted(object sender, PSSaleWS.GetAgencyListCompletedEventArgs Completed)
{
Response.Write("Here");
}

The important piece of information missing is the actual type of the GetAgencyListCompleted event but your error message suggests that it is not an
EventHandler <PSSaleWS.GetAgencyListCompletedEventArgs>
If it is typed non generically as
public delegate void GetAgencyListCompletedEventHandler(object sender, PSSaleWS.GetAgencyListCompletedEventArgs Completed);
then the solution is to explicitly create a delegate of the correct type or let the compiler do it for you automatically.
either
ProntoWS.GetAgencyListCompleted += new GetAgencyListCompletedEventHandler(Proxy_AgencyInfoCompleted);
or
ProntoWS.GetAgencyListCompleted += Proxy_AgencyInfoCompleted;
If this doesn't solve your issue then please supply more information about the actual types involved.
Alan.

Hi Alan!
Thank you for your answer, I got rid of the implicit conversion problem with your approach but Proxy_AgencyInfoCompleted never fires up even I invoke the procedure after ProntoWS.GetAgencyListCompleted += new GetAgencyListCompletedEventHandler(Proxy_AgencyInfoCompleted); statement. Web service doesn't have specific asyncronous methods. Therefore I tried to call the method as follows bur Proxy_AgencyInfoCompleted didn't fire up. Do you have any idea where is the problem? Thank you very much.
ProntoWS.GetAgencyListCompleted += new GetAgencyListCompletedEventHandler(Proxy_AgencyInfoCompleted);
GetAgencyList = GetAgencyList = ProntoWS.GetAgencyList(Agent, User, Password, GetCityName, "TR");

Hello everyone,
I'm making a program that works on some lenovo laptops only, it makes use of Sensor.dll. I've used code below:
[DllImport("sensor.dll")]
private static extern void ShockproofGetAccelerometerData(ref APSReading accData);
I'm not sure how should I check if it exits on the system or not. I'm using lenovo laptop therefore program works fine on my system but If someone runs on different system then it should show a message "system doesn't support" or some other error message. Is it possible to check if certain dll is present in system before importing it??
Thank you

Hi,
the easiest way is by putting your DLL calls (or at least the first one you are going to do) in a try block. The actual lookup of the DLL is postponed till it is actually called, and any error locating it, or its functions, is clearly turned into an exception.
You can find more about it under "Typical Exceptions" in my article here[^].

You'll need to dynamically load the DLL at runtime so you can catch if it's not there.
Searching on "c# dynamically load unmanaged dll" yields examples, like this one...

Thank you guys.
I also found another way of doing it using Files.Exists method of .net.

That still lets you use DllImportAttribute??

In my experience DllImport is not interested in the DLL at all (it is up to the programmer to make sure there eventually will be a DLL file and a function that matches with his prototype).
A C# app builds just fine without the DLL being present; and the calling code throws a DllNotFoundException at run-time whenever it doesn't find the DLL.

Hi,
Iam using VS2010. I have 10 TextBoxes..
In TextBox1 I handled the event for GotFocus,LostFocus...like the following manner...
this.richTextBox1.GotFocus += new System.EventHandler(this.RichTextBox1_GotFocus);
this.richTextBox1.LostFocus += new System.EventHandler(this.RichTextBox1_LostFocus);
private void TextBox1_GotFocus(object sender, System.EventArgs e)
{
TextBox1.BackColor = Color.White;
}
private void TextBox1_LostFocus(object sender, System.EventArgs e)
{
TextBox1.BackColor = Color.LightSteelBlue;
}Like above I need to do all my Textboxes and I need to do the above codings, instead is it possible to have a common GotFocus,LostFocus to all Textboxes to do the above things?
Any Ideas?
Thanks & Regards

Sure, just wire the following handler to several textboxes:
private void tb_GotFocus(object sender, System.EventArgs e) {
TextBox tb=sender as TextBox;
if (tb!=null) tb.BackColor = Color.White;
}
You can do the wiring up at run-time, or using Visual Designer (click the event, choose an existing handler, after you added the above code, that is).

It's perfectly possible to hook multiple items up to one event handler. The sender argument is there to identify the control that raised the event, so you can easily do the following in your handlers:
private void HandleLostFocus(object sender, EventArgs e)
{
TextBox control = sender as TextBox;
if (control == null) return;
control.BackColor = Color.LightSteelBlue;
}

c# - I have a problem with webbrowser control loading local images from a html page(also local).
It does not matter if its a saved page from internet, or made by me... the same problem persist.
BUT, from internet it load the page correctly,all the images are displayed.
What is the catch? I know that I find a solution long time ago, but now I cant find it again... I search everywhere but with no luck. Maybe some luck from you? Thanks.

Without seeing the code it is hard to tell, but check paths for a start.

I really don't think is for much help showing the code, but here it is:
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(llistOfFileNames[listBox1.SelectedIndex].FullName);
webBrowser1.ScriptErrorsSuppressed = true;
webBrowser1.DocumentText = sr.ReadToEnd();
sr.Dispose();
}

why don't you just provide a valid web page, something like:
object item=ListBox1.SelectedItem;
if (item!=null) webBrowser1.DocumentText="<html><body><img src='"+item+"'></body></html>";
BTW: SelectedIndexChanged will also fire when something gets deselected, possible causing unexpected values for SelectedIndex, SelectedItem, etc.

And if, for some reason, you don't have or don't want to use a local file, there is always this[^].

Show the related code - in this case HTML maybe?
Are URLs correct?
Does the hosting process have permissions to access the local images?
