Let me anwser myself.
int a = Convert.ToInt32("0x20", 16); // then a = 32;
|
|
|
|

Because the string "0x10" used by you is in hexadecimal form which uses the fromBase value of 16 in the following method,
public static int ToInt32(string value, int fromBase);
Therefore, you have to use the aforesaid overloaded method with the value of the second parameter fromBase being put at 16, in which case a string containing a hexadecimal number can be correctly converted to a mumber in int format.
For illustration, the example in your question,
int a = Convert.ToInt32("0x10");//does not work
will not work and will have to be used in the following form,
int a = Convert.ToInt32("0x10", 16);
in which case "a" will have the value of 16.
Similarly in,
int a = Convert.ToInt32("0x30", 16);
"a" will have the value of 48.

I am trying to generate proxies using wsdl.exe (Web Services Description Language Utility) tool. When I look into the proxy code (C#), there is no code for the <group> tags from wsdl file.
This .wsdl file provided by another group.
Is the WSDL.exe utility won't support the <group> tags or something is missing the .wsdl file?
ex: (snippets)
<complexType name="Address">
<annotation>
<documentation>complete address.</documentation>
</annotation>
<choice>
<group ref="base:ForeignAddress"/>
<group ref="base:USAddress"/>
</choice>
</complexType>
..
...
<group name="USAddress">
<annotation>
<documentation>US address</documentation>
</annotation>
<sequence>
<element name="addressLine" type="base:AddressLine" maxOccurs="6"/>
<element name="city" type="base:USCity"/>
<element name="state" type="base:State"/>
<element name="zipCode" type="base:USPostalCode"/>
</sequence>
</group>
The generated class:
public class Address {
/// <remarks/>
public object Item;
}
Thanks in advance.

Is it possible to expose a particular instance of an object via .NET remoting? I've read that Marshal will put the object forward, but how do you connect a client to that object?

who is Marshal ??

Alright, I've figured it out. You create an object, initialize it, then expose it using RemotingServices.Marshal. Too cool.

Everything you need is in the System.Globalization namespace. You can use resource files to hold culture-specific variations of text strings and display them based on the target language.
Plenty of examples online if you search for them.

when severity less then 10 it's an information message, so it's SqlError, and in not exists in SqlException i tried what u wrote and on error i don't go to catch block.

I have a 3 tier (biz data and gui layers) web app.
Should I be destroying the BLL or DAL objects after I am none using them?
How come w3wp.exe on the server keeps growing as people use the web app?
Does the fact that none is destroying the objects when they use them have anything to do with it?
We recently moved to the QC box and I am very concerned with the mem usage of w3wp.exe going up as I am testing the site. I am the only user.
Thank you in advance for any advice.

pages are destroyed for you after a page is rendered to the client. Unless you have objects in Application, Session, or Cache you don't need to destrooy anything. What you're seeing with the w3wp process should be normal. It should expand and contract in size based on use.
|
|
|
|
|
Thank you for your feedback.
This is also my understanding for the .Net environment.
Here is also my concern. One user (me), browing a handful of pages balloed the resources used by w3wp to 80MB. I killed the session and nothing was released.
What heppens if 5 users access thensystem at the same time? I am going to set up a similar test, but I am interested in your theory/comments.
Thanks

IIS is designed for multiple clients accessing resources at the same time. Check your IIS settings for optimization. It can handle thousands of users, certainly 5 shouldn't be an issue.

Please provide me advantages/disadvantages regarding the Data Access Application Block in Enterprise Library.

Please avail yourself of the many sources of information on the internet. Look on the MSDN website[^], or just Google 'DAAB Enterprise Library'.
There are also probably relevant articles on CodeProject.

To display an image in the pciturebox,
myPictureBox.Image = Image.FromFile("something.jpg");
Is that what you're looking for? You might try searching CodeProject and MSDN articles before posting.

Thank you for your help.I just want to partly display the image ,not all the image.

I don't think there's anything built into the framework for this; just grab the part of the image you want and construct a new image from it.
