Someone Help me. It's very important.. I can't handle it...

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :Windows Application
The purpose of the exercise is to create a small computer, which will determine the outcome of numerical expressions such as "* 1 3 4. Acceptable numeric operators will be + - * / ^ and like numbers will be integers and / or real (eg 12.93). Among the operators, and their numbers there may be one or more blank (space) characters.

The steps you should follow are:

1. Creation of the class Stack (Stack) which can store data in a table, which will increase strongly. The desired methods of the class are:

Stack - create an empty stack

isEmpty - check if there is data in the stack and returns a reasonable price.

push - dechete data as a parameter and places the table

pop - returns the last element of the list and delete it from the table

top - return the last element of the array.

The operation of the stack used in many computer problems and simulates the process of washing a stack dirty dishes. The new dirty dishes are always placed at the top of the existing stack - in a similar way, the new data mark the end of the stack - and to

COM: Handle Late-bound Events within Visual Basic Using an ATL Bridge


Since a Visual Basic client doesn't handle events directly from late-bound COM objects, it needs some way to capture all the events and parameters launched by any COM object server instantiated at runtime and not known at design time. This article explains how to build a bridge component that does just that. The bridge component transmits the intercepted event data back to the Visual Basic client using another supporting COM object that is capable of holding event data and attributes. The Visual Basic client receives the notification from the bridge and extracts all the information relative to the event from the supporting object.

XMLSerializer don't handle mixed contents properly

mixed content model allows a combination of text and elements in the XML document. we use .net xmlserializer to serialize/deserialize the XML. XmlSerializer don't handle mixed content properly. XmlSerializer handles mixed content models to a degree. XmlSerializer add the text in the xml document, but the position of text is not exactly where they appeared in the original XML document. Let's take a example here is original xml <employee xmlns="http://example.org/xmlserializer">   here is some text...   <id>333-33-3333</id>   here is some more...   <name>Bob Smith</name>   and here is even more... </employee> We deserialize above xml using the xmlserializer then we serialize it back into xml. Now xml document is changed as follows <employee xmlns="http://example.org/xmlserializer">    <id>333-33-3333</id>   <name>Bob Smith</name>   here is some text...   here is some more...    and here is even more... </employee> You see the position of text is changed. I have seen the Microsoft code to serialize/deserialize the xml through reflector. They put text in a string array but position is not saved. Is there any solution or workaround? I don't want to parse the xml by xmlReader. I want fix in the Microsoft generated classes that ar

handle missing types during deserialization

I have situations where I may have a type reference in the object graph that is no longer available because it has been depricated. These are objects defined outside the control of my serialization API. I need the deserializer to just ignore these objects and move on without erroring out with: "Unable to find assembly 'MyMissingAssembly, Version=, Culture=neutral, PublicKeyToken=null'." My question is not why the error is occuring. I understand why. But how do I handle this error gracefully, have the missing types skipped, and continue deserializing the rest of the object graph? I have experimented returning a dummy class through the VersionDeserializationBinder.BindToType() method so that I can do type substitution with types I control. This works but I need a way to discriminate for which types I should do this for. So I need to know if the deserializer has access to the type in question before it attemts to deserialize the object. If only it could tell me it can't find it before it throws the error.  

Best approach to handle concurrent requests in winforms

I have a windows client application which would be used many users. This application submit requests to run a workflow (note that this is not a WWF or WCF service, its a class library thats gonna do some processing). What would be the best approach to code this? Would processing each request on a separate thread be a correct way? I am a newbie at this. PLease help. Thanks!

How to handle *many* date fields?

I have put together a cube for auto loan analysis. It is populated via monthly snapshots. There are many actions taken on these loans that have a date stamp associated with them (repossess/resell/refinance, etc.). These fields are on each row and only populated if utilized, else NULL. In the design of the cube, all of these fields were specified as being associated with date dimensions. Now that I am actually building this thing out, my date dimension is aliased (role playing) 15 times! This seems ridiculous to me as many of these date fields are not useful for analysis, per se. Primarily the analysts need the ability to filter based off of them. Ie. Display measures [x],[x1] in a pivot table where reposession date > '[Jan 2005], etc. They use excel 2007 for analysis. Is there another way to handle all of these auxiliary/sparsely populated dates besides creating dimensions for them?   Thanks for your help!
