Hi,
You can just add eventhandler for the button in code-behind file as follows :
button1.Click += new RoutedEventHandler(button1_Click);

Hi,
Just try to put your code in try & catch block. Because you are getting datatype mismatch error. The conflict is between the data you are passing and the data-type of the fields in database.
May be error is due to date field.

There are many ways to acheive this, the easiest is to adjust the constructor for form2 to accept a textbox argument and store that as a variable in the form2 class in the constructor. Then you can access or change any of the form1.textbox properties from form2.

Hi
I have a web browser object that loads a given page, and once its loaded i want to extract all the images from the DocumentStream and get them in an Image or Bitmap format.
Anyone know a way of doing this?
I have tried several methods but none seem to work.
I've noticed that right click > Save As seems to be instant, ie not redownloading the picture, which is my goal. Any idea what methods Save As uses to save it without redownloading?
Any help appreciated...

I am a bit confused about using the InvariantCulture flag while converting a string to double.
Can someone please guide me as to how do we take care that when we are converting a string to double it should work in different culture settings(like English which uses "." and french which uses "," for decimal separators). My idea is that if I give the InvariantCulture flag then Double.Parse or Convert.ToDouble can convert any string correctly.
Thanks,
Pankaj

Hi all, I've a problem with remoting: in order to connect to a remote object I have to open a port on the server. But then the server also asks for a connection with the client and the port used is random if in the client remoting file there is
<channel ref="tcp" port="0" exclusiveaddressuse="false">
or the specified port otherwise. My problem is that if I have to go behind a firewall I have to open the port, so I specify a port but then... when I try to start a second instance of my app I get an exception because the channel is already in use. I could ask the customer to specify a set (or range) of ports, but I wonder if there are better alternatives. For example, how do applications like P2P or web browser deal with multiple connection? I suppose that they have to accept incoming connections as well...

In my logging code, I want to display the name of the method that wrote to the log. How can my Log method get the name of the method that called it?
I'm thinking of something like the .TargetSite of an Exception (except I'd prefer not to throw an exception ... unless that's how to do this).
|
|
|
|
|
Let me make this more generic:
- how, in code, can I stop and get the stack trace up to that line of code? Hopefully I can do this without stopping and throwing an exception and reading the stack trace from the Exception object. I'm sure that's a performance hit...
|
|
|
|
|
By using System.Diagnostics.StackFrame like this:
public static void Main()
{
Func();
RL();
}
public static void Func()
{
//Get stack with line numbers
System.Diagnostics.StackTrace Stack = new System.Diagnostics.StackTrace(true);
foreach(System.Diagnostics.StackFrame Frame in Stack.GetFrames())
{
WL(Frame);
}
}

Thanks. That is exactly what I was looking for. Unfortunately, I never got email about your reply! So I went through the Help files and found this myself. I was just coming back to answer my own question when I saw your reply.
However, I'm curious how expensive *this* is, too...
