I have a .rdlc report, grouped.
Inside each group, I have an Id. Some of them will be positives, and others will be negative.
I need the difference between de quantity of positives Id's and negatives Id's
Something like
=CountDistinct(Fields!Id.Value) where Fields!Id.Value > 0 - CountDistinct(Fields!Id.Value) where Fields!Id.Value < 0
How Can I do that ? I'm thinking on a function, but I want to know if there is a simply way
Edit: An Id can be more than once time in each group, that's why I use CountDistinct
You can try this:
CountDistinct(IIf(Fields!Id.Value > 0, Fields!Id.Value, Nothing))
create 2 global variables. one for positive and one for negative.
Then create a new formula that counts them like the following:
WhilePrintingRecords;
IF (GroupName ({your_group_name}) > 0) THEN
Positive var = Positive var + 1;
ELSE
Negative var = Negative var + 1;
You can actually look for your group in the formulas and drag it to the editor while writing the formula.
Since its a operation in group level, the records should be read first. Thats why we use whilePrintingRecords rather than whileReadingRecords.
Hope I understood your question right.

I am trying to add the user inputs using a while loop and If statements. I am having trouble figuring out how to add all the userNumbers to each other. Any help would be appreciated.
//variables
Declare Integer userIn = 0
Declare Integer total = 0
//read numbers and calculate
While decision == decY
Display “Please enter your numbers: ”
Input decision
If UserIn > 0
Display userNumbers
Set total = userIn + 1
Display “Would you like to enter another number Y/N?”
Input decision
If decision == decN
Display “Done reading numbers, your total is ”, total
End If
End If
End While
Decide on a separator for the input, unless they're only allowed to enter a single number at a time in which case you can skip to 3.
Use string splitting to cut the input up and then loop through that list with for, while, do, until, or etc.
Create a sum total variable and add each input value to it, e.g. sum = sum + split_input[index], or if it will only allow a single input at a time sum = sum + input.
Some Notes:
Adding a value to a variable can be shortened to variable += value to add a value to an existing variable and assign the result to the variable, but not all languages support this syntax.
Not all programming languages start at 0 for list indices, so be sure to change the starting index accordingly.
I am currently writing a Swift application and parts of it require making sure certain user inputs add up to a specified value.
A simplified example:
Through program interaction, the user has specified that totalValue = 67 and that turns = 2. This means that in two inputs, the user will have to provide two values that add up to 67.
So lets say on turn 1 the user enters 32, and then on turn 2 he enters 35, this would be valid because 32 + 35 = 67.
This all works fine, but the moment we verge into more than one decimal place, the program cannot add the numbers correctly. For example, if totalValue = 67 and then on turn 1 the user enters 66.95 and then on turn 2 he enters .05 the program will return that this is an error despite the fact that
66.95 + .05 = 67. This problem does not happen with one decimal place or less (something like turn 1 = 55.5 and turn 2 = 11.5 works fine), only for two decimal spots and beyond. I am storing the values as doubles. Thanks in advance
Some example code:
var totalWeights = 67
var input = Double(myTextField.text.bridgeToObjectiveC().doubleValue)
/*Each turn is for a button click*/
/*For turn 1*/
if inputValid == true && turn == 1 && input < totalWeights
{
myArray[0] = input
}
else
{
//show error string
}
/*For turn 2*/
if inputValid == true && turn == 2 && input == (totalWeights - myArray[0])
{
myArray[1] = input
}
else
{
//show error string
}
If you want exact values from floating point then the float/double types will not work, as they are only ever approximations of exact numbers. Look into using the NSDecimalNumber class from within Swift, I'm not sure what the bridging would look like but it should be simple.
Here is an example of how this could work:
var a = 0
for num in numlist {
a += num
}
var result = false
if a == targetnum
result = true
I haven't tested this out, but if numlist is an array of double then it should work for any input that is a valid number.
One problem I just realized is that there is an issue with doing an equals with doubles, as rounding will cause problems for you. I am not going to show it, but if, while reading in the inputs you keep track of how many numbers to the right of the decimal place, then multiply all of the values by that number of tens, so 66.95 * 100 to get it all as an integer, then add, then do the comparison, after multiplying the targetnum by the same value (100).
Unfortunately there is no ideal solution to this. We must use approximation type comparison.
For example, instead of checking:
if val1 == val2
we must try something like:
if val1 > (val2 - .0005) && val1 < (val2 + .0005)
I have a bunch of values, for example: [1,2,14,51,100,103,107,110,300,505,1034].
And I have a pattern values, for example [1,10,20,100,500,1000].
I need to get the best 'suitable' value FROM pattern. In my example it is 100. How can I detect this value?
Example from life. The app has a bunch of distances between user position and some objects. The app also has a preset filter by distance: [1 meter, 10 meters, 20 meters, 100 meters]. I heed to set the filter by default not just to the first value (1 meter in my example), but to the value which match the bunch of distances the best way(100 meter in my example). I need to detect one value.
Thank you for help and any ideas.
I would say create a function like this (this is not real code) :
var ratio1 = 0.66
var ratio2 = 1.5
function Score(currentPatternValue, arrayOfValues)
{
count = 0
for each value in arrayOfValues <br>
if value > ratio1 * currentPatternValue AND value < ratio2 * currentPatternValue<br>
count++<br>
return count
}
then you run this for each value in your pattern values and pick the one with the highest score returned from that function
I am trying to keep the last n elements from a changing list of x elements (where x >> n)
I found out about the deque method, with a fixed length, in other programming languages. I was wondering if there is something similar for VB6
Create a Class that extends an encapsulated Collection.
Add at the end (anonymous), retrieve & remove from the beginning (index 1). As part of adding check your MaxDepth property setting (or hard code it if you like) and if Collection.Count exceeds it remove the extra item.
Or just hard code it all inline if a Class is a stumper for you.
This is pretty routine.
The only thing I can think of is possibly looping through the last 5 values of the dynamic array using something like:
For UBound(Array) - 5 To UBound(Array)
'Code to store or do the desired with these values
Loop
Sorry I don't have a definite answer, but hopefully that might help.
Here's my simplest solution to this:
For i = n - 1 To 1 Step -1
arrayX(i) = arrayX(i - 1)
Next i
arrayX(0) = latestX
Where:
arrayX = array of values
n = # of array elements
latestX = latest value of interest (assumes entire code block is also
within another loop)

I'm working on a QTP test for a web page where there are multiple HTML tables of items. Items that are available have a clickable item#, while those that aren't active have an item# as plain text.
So if I have a set of ChildObjects like this:
//This is the set of table rows that contain item numbers, active or not.
objItemRows = Browser("browserX").Page("pageY").ChildObjects("class:=ItemRow")
What is the simplest way in QTP land to select only the clickable link-ized item #s?
UPDATE: The point here isn't to select the rows themselves, it's to select only the rows that have items in them (as opposed to header/footer rows in each table). If I understand this correctly, I could then use objItemRows.Count to count how many items (available and unavailable) there are. Could I then use something like
desItemLink = Description.Create
desItemLink("micclass").value = "Link"
objItemLinks = objItemRows.ChildObjects(desItemLink)
To get the links within only the item rows?
Hope that clarifies things, and thanks for the help.
I think I have this figured out.
Set desItemLink = description.create
desItemLink("micclass").value = "Link"
desItemLink("text").RegularExpression = True
//True, Regex isn't really required in this example, but I just wanted to show it could be used this way
//This next part depends on the format of the item numbers, in my case, it's [0-9]0000[0-9]00[0-9]
For x = 0 to 9
For y = 0 to 9
For z = 0 to 9
strItemLink = x & "0000" & y & "00" & z
desItemLink("text").value = strItemLink
Set objItemLink = Browser("browser").Page("page").Link(desItemLink)
If objItemLink.Exist(0) Then
//Do stuff
End If
Next
Next
Next
Thanks for your help anyways, but the code above will iterate through links with names in a given incrementing format.
