NVelocity Macro Parameter Not Evaluating
Jun 14, 2011
I'm looking to create an inline function (method) inside my NVelocity template. The solution to this appears to be to use Velocimacros. So, I mocked up the following template to test:
#macro( getOutput $one $two $three )
<td>$one</td>
<td>$two.Item2</td>
<td>$three</td>
#end
[Code] .....
When I run the template, the problem I'm having is that the output from the macro parameter $three is literally "$item.Item3" instead of evaluating to #3/3/2003#. (BTW - this happens with any of the 3 items in the tuple if they are passed with the .Item call, so it isn't about the data type). I can make a variable and pass it just fine ($one1). I can pass the tuple itself and call the .Item property inside the macro ($item.Item2), but for some reason I cannot call the .Item property when passing the argument to the macro.

I'm have a program (GUI) that interfaces with excel to execute macros. We're using Microsoft.Office.Interop.Excel to call/run the macros and this works great.What I can't figure out is a good way to cancel the macros from the GUI.One idea we had was to use the excel.application variable that runs the macros to write a "stop" value to a specific cell in the workbook, and in the macros (they are all mostly loops), check for the "stop" value in that cell. This crashes my GUI with this The program '[2188] BVLReports.vshost.exe: Managed' has exited with code -336589910 (0xebf00baa).And excel gets tied up, and won't respond. I know how to Exit Sub from within the macro if the "stop" value exists, so I don't need answers on how to check/cancel from inside the macro. Any ideas on a better way to write this "stop" value or a better way to cancel the macros externally?

So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:vb.net If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:vb.net If PGN = &HEF007E And PGNData(0) = &H58 Then If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False

Does anybody know of a call in vb.net that will evaluate a string expression. For example, how would one evaluate the expression "(1+2)*(3+4)"?I've looked all over and it seems that people are writing their own parsers. There has to be a better way. After all these years, VB.Net must have something that will take an expression and evaluate it.
Dim strMyExpression as string = "(1+2)*(3+4)"
msgbox( VBEvaluate(strMyExpression))
and the result would be 35.Also, when will microsoft start to use google as the search engine for these forums? Bing really sucks. Searching for "Evaluating a string expression in VB.net" gives the most bizarre links.

I have a application that allows the user to enter a series of nested filtering commands. E.g "Name starts with x or ((Description contains y or Property1 is On) and Property2 > 100)"
I can preprocess this and distill it down to a string in the form of an expression of True and False's ie, To "True or ((False or True) and False)" Is there a simple way to have this final expression evaluated without having to write a complex evaluator myself?
I have seen a method of evaluating this by compiling a dummy function at runtime but as I need to process this against possibly thousands of records that solution is too slow.
BTW These are not all fields in a database so I cannot use Queries or SQL etc.

I store a formula in the database such as the following:GrossIncome+(Overtime/0.5)-Deductions=BasicNetIncome
I am able to substitute the string representations with actually values entered, thus:1000+(150*0.5)-100=BasicNetIncome
Then I remove the '=BasicNetIncome', thus:
1000+(150*0.5)-100
How can evaluate the above equation to return a result:

Is there a method that allows me to evaluate a mathematical expression in a string? Example (Not actual Code):
Input = "2+2"
Output = SomeMethod(Input)
Output = 4
Update: Nevermind, I found a way around it by using DataTable.Compute.

We are working on a poker game as a class project. My part is to evaluate and then determine the value of a players hand. We are evaluating from highest to lowest (ie. determining whether the player has a straight flush, 4 of a kind, full house, flush and then going all the way down to a high card only "worthless hand"). My part is evaluating the 2 pair, 1 pair, and nothing hands. The hand will be a two-dimensional array with the row(0 thru 12),column (0) containing the numeric "face" value of the cards and the column(1) containing the value assigned to the suite (1=clubs, 2=diamonds,3=hearts,4=spades). I have NO IDEA where to even begin this evaluating procedure.

I am making a checkers program and I am in the phase of starting to evaluate jumps. This is what I currently have so far and allow me to fill you in a bit before you look at the code. Checker pieces are white/green. Each checker is created as a label at runtime and in the tag property a struct is held that possesses all of the information reguarding current and previous checker state.
The problem I am having is that as this sub runs each opposing checker is evaluated for jump capabilites which is all fine and dandy. It is even alright that currently if a jump is executed that the same side will continue to evaluate through the sub looking for additional jumps and if they are found they will be made because that is how it is currently coded. What I am trying to do is find a way to evaluate each piece that can jump. So if checker1 can only make one jump and checker2 can make a triple jump checker2 needs to be the guy making the jump and I honestly don't know how do start that. I am forseeing global vars being created to hold information or even a structure and taking the one that changes the most. If two checkers can only make 1 jump then I will rand the one that gets to jump (not looking to win any awards for AI here). Anyhow, any suggestions on how to start this, at least saving the information throughout the sub even if it is called recursively?

[URL]From what we can see on MSDN, it says to be careful about which expressions we put as they change from language to language. My question is: what are the supported languages for writing those expressions? If various languages can do it, how does it detect which language is being used?I've made my class in CLI, and coded the expression in c#, being that it works. I've tried in c++/CLI, but that way it doesn't.
Here is my code:
[DebuggerDisplay("z = {ToString()} Norm = {System.Math.Round(Norm,2)} Angle = {System.Math.Round(Angle, 2)}")]
Now, trying it the c++/CLI way:
[DebuggerDisplay("z = {ToString()} Norm = {System::Math::Round(Norm,2)} Angle = {System::Math::Round(Angle, 2)}")]
My assumption is that it will always read the expression as c# code. Is this true?

I have an EnumerableRowCollection that looks like the following:
VendorCode | GroupType | Variance
01165 G .16
01165 G .16
01165 CH .16
01165 CH .18
07754 G .25
07754 G .25
07754 G .39
Essentially, this is a massive list of vendor codes, their groups, and price variances. I need to compose a query that will create a distinct list vendor codes and group types. The catch, however, is that I need to evaluate all of the variances associated with that particular VendorCode/GroupType to see if they are all the same - it they are not, I need to return some way of signifying that the group has a "custom" variance, otherwise it needs to return the value (ie: if they are all .16, then return .16, if there are multiple values, return "custom")
The result would look like this, based off of the list I showed above.
VendorCode | GroupType | Variance
01165 G .16
01165 CH custom
07754 G custom
I have no trouble getting a distinct list of VendorCode/GroupType - this is what I have so far:
Dim distinctList = From q In query Select q.VendorCode, q.GroupType, (evaluated q.Variance here?) Distinct
(where "query" is an EnumerableRowCollection(Of (anonymous type)))
I'm at a loss, though, on how to evaluate the variance property to get the result that I need?

One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.

I am working on a poker game and I have the game setup the way I want it in terms of graphics and I have the code programed to deal the cards out exactly how I want them. Granted, the code is very simplistic, but functional for a new programmer like myself. I'm sure there are other more efficient ways to code my game, but I like mine so far because I can at least understand the majority of it. With that being said, here are a few problems and questions that I have.
1. How come when all 12 cards are dealt out I have some cards repeating in the game? For example, I get queen of diamonds in more than one picture box when I only want the card to be dealt once and then removed until the next game.
2. I was hoping to have a button 3 to clear all the boxes, basically resetting the game to the next game. When I hit button 3 it only clears the contents of picturebox 10 and 12.Other notes: I have the deal down the way I want it. It deals the first 10 picture boxes and a second button deals the 11 and 12 picture boxes.
3. I know this is my next step so I want to post it with the code I currently have. I want to start taking my project one step further by evalutating each of the three rows of cards (3 rows of 3 cards each - I'm not worried about the dealers hand (picture box 10, 11, 12 yet). So I want to evaluate a row of pictureboxes against a "pay scale" and display the win in a text box or label next to the 3 card hand. For example, Q of diamonds, Q of Clubs, Q of spades would win 15, etc. ( have a weird feeling I may have to change the names of the cards (I have them named card1, card2, etc. right now) to something that identifies them in order to evaluate the hands.
Here is the code that I currently have. I'm using visual basic.
Public Class Form1
Dim Rndm As New Random
Dim myPB(11) As PictureBox
Dim HiddenCards As New List(Of String)
