Custom code in ssrs 2005

hi sir
i am fresher,
i need breif about custom code in ssrs,
what is cutom code,
why it is used,
what is the perpose of this code...
help me to learn.
thank you.

custom code is used mostly for implementing functionalities which cannot be done using standard features available in SSRS. Custom code should be written using .NET language. If you want to share same code across multiple reports you should make it into
a dll and reference it from all the required reports.

Custom Code in SSRS 2008

Hi,
I am trying to write Custom Code in SSRS for Age Calculation for two requirements in the same report,But report is giving error #Error in expression with my below code.
whole logic is same for both but only two lines are different,Do i need create two functions or can i use them in one function.Please guide me.
1)Age in Years (Ex: 4)
2) Age in Years + months (ex: 3 Years 6 months)
My SSRS Custom Code:
Public Shared Dim Years as Integer
Public Shared Dim Months as Integer
Public Shared Dim Days as Integer
Public Shared Dim Age as Integer
Public Shared Function CalAge(ByVal D1 As Datetime,ByVal D2 As Datetime ) As Integer
Years=Year(D1)-Year(D2)
Months=Month(D1)-Month(D2)
Days=Day(D1)-Day(D2)
If Days < 0 then
Months=Months-1
End if
If Months < 0 then
Years=Years-1
End if
If Months < 0 then
Months=Months+12
End If
Return Years
If Months=1 then
Age=Years+" Years " + Months + "Month"
else
Age=Years+" Years " + Months + "Months"
End If
Return Age
End Function

hi Guys,
I have finally changed my custom code to below :
Public Shared Dim Years as Integer
Public Shared Dim Months as Integer
Public Shared Dim Days as Integer
Public Shared Function CalAge(ByVal D1 As Datetime,ByVal D2 As Datetime ) As Integer
Days=DatePart(DateInterval.Day,D1)-DatePart(DateInterval.Day,D2)
Months=DatePart(DateInterval.Month,D1)-DatePart(DateInterval.Month,D2)
Years=DatePart(DateInterval.Year,D1)-DatePart(DateInterval.Year,D2)
If Days < 0 then
Months=Months-1
End If
If Months < 0 then
Years=Years-1
End If
If Months < 0 then
Months=Months+12
End If
Return Years
End Function
Public Shared Function CalMon(ByVal D3 As Datetime,ByVal D4 As Datetime ) As Integer
Days=DatePart(DateInterval.Day,D3)-DatePart(DateInterval.Day,D4)
Months=DatePart(DateInterval.Month,D3)-DatePart(DateInterval.Month,D4)
Years=DatePart(DateInterval.Year,D3)-DatePart(DateInterval.Year,D4)
If Days < 0 then
Months=Months-1
End If
If Months < 0 then
Years=Years-1
End If
If Months < 0 then
Months=Months+12
End If
Return Months
End Function
and using expression in SSRS fo display like this :
=IIF((Code.CalMon(Parameters!AgeCalcDate.Value,Fields!StudentBirthDate.Value))=1,Code.CalAge(Parameters!AgeCalcDate.Value,Fields!StudentBirthDate.Value) & " Years " & Code.CalMon(Parameters!AgeCalcDate.Value,Fields!StudentBirthDate.Value)
& " Month ",
Code.CalAge(Parameters!AgeCalcDate.Value,Fields!StudentBirthDate.Value) & " Years " & Code.CalMon(Parameters!AgeCalcDate.Value,Fields!StudentBirthDate.Value) & " Months ")
got the correct solution.

Using custom code in SSRS PDF rendering

Hi,
I have a written some custom code ( a simple function to maintain a counter ) in SSRS Report properties.
Everything works fine when I render the report in Report Viewer, but the custom code is not recognized when I render the report to PDF.
What is wrong with my code?
There is no error reported. The custom code is just getting skipped when I render to PDF.
My custom code is as follows..
Public Shared Dim iCounter AS Integer = 1
Public Function IncrementCounter(SomeValue As Boolean) As Boolean
iCounter = iCounter + 1
Return SomeValue
End Function
Public Function GetCounter() As Integer
Return iCounter
End Function
and my call to the custom code is..
=code.GetCounter()

Hi ha_emp,
From your description, it seems that custom code work well when you preview the report. While it would be skipped when the report is exported to PDF. After testing the custom code in my environment,I find that the custom code will run again when exporting
the report, so when we run the report on Report Server and export it to PDF, the custom code will be run twice, the value will be counted twice.
Based on my research, I find that we can delete the “Shared” in the first row of the custom code to fix this issue. Then the custom code will works well on Report Server.
If there are any misunderstanding, please elaborate the issue for further investigation.

Hi Simran08,
According to your description, you fail to add your report to CRM due to the custom code. Right?
In this scenario, based on my knowledge, I find two issues in your custom code.
You pass the array Items as argument to the function. This array is from the LookupSet() function. However, it returns an concatenated string with commas. When you convert it into decimal, it will throw error.
In your For Each loop part, we should follow the format below:
For Each element In group
[statements]
[Exit For]
[statements]
Next [element]
It seems you miss Item after Next.
If you still have any question, please feel free to ask.

How to dynamically set width of SSRS columns in custom code?

How can I change the width of a table column based on a parameter value using custom code in SSRS?
If the parameter value is "Excel", I'd like the width to be 2 inches. If the parameter value is "Standard", I'd like the width to be 1 inch.

Hi mmx_pdx,
Based on my research, we can only type static values for the width size in report. In Reporting Services, it not supported to set the size of width based on an expression currently. This is by design.
Personally, I recommend you that submit this suggestion at
https://connect.microsoft.com/SQLServer/. If the suggestion mentioned by customers for many times, the product team may consider to add the feature in the next SQL Server version. Your feedback is valuable for us to improve our products and increase the
level of service provided.
Thanks for your understanding.

How to control or manipulate a report parameter through SSRS Custom Code

Hi,
In reporting services 2005 or 2008, is it possible to control the parameters inside the custom code of a report?
for example:
Let's say I have a parameter that displays the following value:
Red
Green
Blue
In typical scenario I can select one of the values or I can select all of the values then click the View Report button in reporting services.
I know that this approach is much easier to do if I have an external application like ASP.Net and from there I'll just add report viewer and control the parameters to be passed and then generate the report.
In the report I added text box that will serve as a hyperlink to refresh report:
In the Text Box Properties\Action tab. Is it possible to control the selection of values through a custom code(SSRS Custom Code) then the report will be automatically refreshed?
thanks,
Joefer

Not sure about doing a multiple selection. But you can pop up an input box to get the input on the fly.
Add the below custom code and expression for the above parameter
Public function Getparamvalue() AS STRING
Dim x as STRING
x = InputBox("Enter Red / Blue / Green")
Return(x)
End function
=Code.Getparamvalue()

Custom code dll as a data source for an SSRS report

I'm trying to create a report which relies on using some custom code written in VB.net. I am using the custom code to access the Server Management Objects SMO API in MSSQL 2012. I am able to supply an MSSQL object name (a database table
for example)and then return a list of dependant objects using the dependency walker class (stored procedures, triggers, UDF's, other tables etc.) which rely on the parent object if you will. I am able load the results into a dataset in the custom code. My
question is how can I get that dataset to be consumed as a data source and appear in my report. I've read many articles on how to use scripts to supply values for various report property settings. I just haven't seen an example of using a dll
to supply a dataset. I am assuming it is possible. Any thoughts or advice would be appreciated. Cheers

Hi mdmck,
According to your description, you want to create an SSRS report with custom code as data source, right?
To use custom code in Reporting Services, we need to add a reference to your custom assembly, create a new CodeGroup for your custom assembly, and then grant full trust permissions. For detail information, please refer to the following steps:
Open the report that will reference the custom assembly.
On the Report menu, click Report Properties.
In the Report Properties dialog box, click the References tab.
Under References, click the ellipsis (...) button that is next to the Assembly name column header.
In the Add References dialog box, click Browse.
Locate and then click the custom assembly. Click Open.
In the Add References dialog box, click OK.
In the Report Properties dialog box, click OK.
If the custom assembly requires more permissions than the default Execution level permissions, we need to create a new CodeGroup for your custom assembly, and then grant full trust permissions.
Here are relevant threads you can reference:

SSRS 2005 report: Cannot bulk load Operating system error code 5(Access is denied.)

I built a SSRS 2005 report, which calls a stored proc on SQL Server 2005. The proc contains following code:
CREATE TABLE #promo (promo VARCHAR(1000))
BULK
INSERT #promo
FROM '\\aseposretail\c$\nz\promo_names.txt'
WITH
--FIELDTERMINATOR = '',
ROWTERMINATOR = '\n'
SELECT * from #promo
It's ok when I manually execute the proc in SSMS.
When I try to run the report from BIDS I got following error:
*Cannot bulk load because the file "\aseposretail\c$\nz\promo_names.txt" could not be opened. Operating system error code 5(Access is denied.).*
Note: I have gooled a bit and see many questions on this but they are not relevant because I CAN run the code no problem in SSMS. It's the SSRS having the issue. I know little about the security of SSRS.

I'm having the same type of issue. I can bulk load the same file into the same table on the same server using the same login on one workstation, but not on another. I get this error:
Msg 4861, Level 16, State 1, Line 1
Cannot bulk load because the file "\\xxx\abc.txt" could not be opened. Operating system error code 5(Access is denied.).
I've checked SQL client versions and they are the same, I've also set the client connection to TCP/IP only in the SQL Server Configuration Manager. Still this one workstation is getting the error. Since the same login is being used on both workstations and it works on one but not the other, the issue is not a permissions issue. I can also have another user login into the bad workstation and have the bulk load fail, but when they log into their regular workstation it works fine. Any ideas on what the client configuration issue is? These are the version numbers for Management Studio:
Microsoft SQL Server Management Studio 9.00.3042.00
Microsoft Analysis Services Client Tools 2005.090.3042.00
Microsoft Data Access Components (MDAC) 2000.085.1132.00 (xpsp.080413-0852)
Microsoft MSXML 2.6 3.0 5.0 6.0
Microsoft Internet Explorer 6.0.2900.5512
Microsoft .NET Framework 2.0.50727.1433
Operating System 5.1.2600

SSRS custom code for count in Report Footer

Hi All,
Please help me with the custom code used for below requirement
Debtor Name current 30+days 60+days 90+days
aaa 7000 0.00 0.00 10.00
bbb 5000 0.00 20.99 3.00
ccc 1000 0.00 0.00 0.00
Expected result in report footer :
0 1
2
if the value of 30+ , 60+ and 90+ columns >=1 then i have to display the count in Report footer,for that i have tried using a custom code like below :
Shared Dim OD As Integer=0
Public Shared Function Test(ByVal OP As Decimal) As Integer
If OP >= 1 Then
OD = OD + 1
Else
OD = OD
End If
Return OD
End Function
and using below code to display
Code.Test(Overdue)
but when i use this code in report footer is not displaying correct value.Please guide me where i am going wrong.
Please let me know if you need any other details.
Thanks in advance,
Samhith.

Hi Samhith,
Per my understanding you what to count the rows which values >=1 and display them at the bottom of the table, you are trying to use the custom code to do this but failed, right?
I have tested in my local environment and find the custom code is not correctly, and I have an alternative method which is more easy and can work in both table and matrix.
As Vaibhav Chaudhari also mentioned that we can use the CountDistinct function, but more correctly, we can use the count() function and the RunningValue() function, because CountDistict will not count the duplicated values if they >=1.
Please find the expression as below:
=Count(IIf(Fields!Yourfield.Value>=1 , Fields!Yourfield.Value, Nothing))
OR:
=RunningValue(IIf(Fields!Yourfield.Value>=1 , 1, Nothing),Sum,"DataSetName")
If you still have any problem, please feel free to ask.

SSRS Custom Code Error There is an error on line 0 of custom code: [BC30205] End of statement expected.

I am receiving this error with the following code, which counts the number of work days between two parameters and I don't see the problem. Please help.
Public Function GetDateCount(ByVal StartDate AS DateTime, ByVal EndDate AS DateTime) AS Integer
Dim TempVal AS Integer
DimTotalDays AS Integer
TotalDays = 0
TempVal = DateDiff(DateInterval.Day, StartDate, EndDate) + 1

TotalDays = TotalDays +1
End If
StartDate = DateAdd(DateInterval.day, 1, StartDate)
Next
Return TotalDays
End Function

Hi CNet Vase,
According to your description, you want to use custom code to count the number of work days between two parameters in the report, but when you run the report, an error occurs.
I reproduced the issue in my environment, the error message: ‘DimTotalDays’ is not declared. The error is caused by there is no space between Dim and variable TotalDays, so the system regards it as a unit. To fix this issue, please type
space behind the word Dim like below:
Dim TotalDays AS Integer
If there is any misunderstanding , please feel free to let me know.

SSRS Running Totals Custom Code

I have a report in which I need to total a column with an expression and created simple code to have a running total. When I run the report through report builder, the total only reflects the current page (it is 6 pages long) but if I export the report
out to Excel, the total is correct.
Below is the code:
Public running_roy as Double = 0
Public Function roy_tot(ByVal cust_type, ByVal roy, ByVal ret_value) as Double
Dim temp_var as Double
if cust_type = 0 then
running_roy = running_roy + roy
if ret_value = 0 then
temp_var = roy
else
temp_var = running_roy
end if
ELSE
temp_var = 0
end if
return temp_var
End Function
If I change the Public variable to "Public Shared" the totals change as I flip back and forth between the pages in report builder.
Any suggestions?

Hello alan2624,
Thanks for your clarification.
In the report, the custom code will be compiled as a class before it is used. Every time the page is loaded, the class on the page will be initialized. The un-shared (non-static) instance will be reset. Therefore, you will see the value is reset back to
zero if the public variable is not announced as "Shared". If you announced it as shared, then the variable is on the class level. It will not be changed by instance initializing. In addition, any operations on the variable will be recorded. This is not the
bug, but it is by design of the VB.net code.
If you export the report to the Excel, I think it will only generate a single page, and the total value is only the last one. It should be correct. If it is used in the pages in browser, I suggest you need design your code carefully for VB.net design.
If you have any questions about this issue, please let me know.

How to allow custom colors to SSRS Pie-Chart?

Hi,
I have a pie-chart in my report.
Can anybody please tell me How I can allow custom color to each part/slice of the piechart..??or How i can assign cutom pallete to pie-chart?
BhushanBhushan

Hi,
I think u r using one data Field and One category Field in the Graph.
Then We have use Code Option
-----Add this in Code
Private colorPalette As String() = { "Teal", "Gold", "Aqua"}
   Private count As Integer = 0
Private mapping As New System.Collections.Hashtable()
Public Function GetColor(ByVal groupingValue As String) As String
        If mapping.ContainsKey(groupingValue) Then
            Return mapping(groupingValue)
        End If
        Dim c As String = colorPalette(count Mod colorPalette.Length)
        count = count + 1
        mapping.Add(groupingValue, c)
        Return c
    End Function
Finally add this Expression in the Fill Option. And we can add more colors in the Code based on no. of Category
=Code.GetColor(Category_Field)
for example =Code.GetColor(Fields!Zone.Value)
Regards,
Thiyagu
