View 2 RepliesI'm trying to use LINQ to XML to create an Excel spreadsheet. I created a template spreadsheet, exported it to XML, pasted the XML into my code and then began to edit it. When I try to create a set of XElements using LINQ, I get these errors:
The first squiggle under <Cell> says "attribute specifier is not a complete statement"
The second under ss says "'>' expected"
The third under Type says "'Type' is a type and cannot be used in an expression"
Ignore the error under "Lot 1..." I will be putting an expression hole there.
The squiggle under </Cell> says "Identifier expected".
I have an enum set with custom attributes. need to retrieve the attribute value in single statement ...
Public Enum Messages
''' <summary>
''' <value>(MessageText : Do you want to save ?)</value>
''' </summary>
<StringValue("Do you want to save ?")> Save
[Code] .....
Now I needed to retrieve the enum value like something below.
Messages.Save.GetType().GetCustomAttributes...... something is possible in single statement itself?
I am having problem with the coding of this (endless loop) and formatting of summary boxes before tests are complete that should not happen. (the overall goals is to have a separate validation procedure that does not calculate or dat displays are not performed until after call function is complete and valid. The validation that takes place are that two boxes are filled in - one is text and the other is a numeric value. (using vb 2008)

The problem, The INSERT statement works fine in the form load but not in the button click event?
I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

View 3 RepliesI'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)
View 4 Replieshow to use them then before, but am still a little confused with a few aspects. Here goes:
1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?
2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?
3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?
4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?
5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?
The problem im having grabbing the attribute names out of xml document. Here is the snippet:
<RUNWAY name="02X" length="3507" slope="-0.11" level_off_height="2228">
I have created a loop to display the results. In the snippet above, how do i grab the attributes name(name, length, slope, and level_of_height). I have used reader.name is giving me RUNWAY which is correct as the elements name. I tried getAttribute and it give me all of the values of the attributes, but not there name.

In C# if you start a snippet you press Tab to cycle through the snippet elements, and press Enter to complete and exit the snippet.
In VB.NET you still use Tab to cycle through the snippet elements, but how do you end the snippet? Enter doesn't work and I can't figure out the correct keyboard shortcut
I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?
