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.

Running totals: Custom Reset via Formula? (VS 2005)
Post Author: PunchngMrGrumpy
CA Forum: .NET
Hi All,I have attached a screenshot to help make up for my inability to describe the situation I'm dealing with here.I
have three groups within a report that currently use distinct Running
Totals fields that Reset at the group levels that I assigned. I am
attempting to create a single Running Totals field for all 3 groups
that will reset depending on which Group is being calculated at the
moment so that I don't have to have 3 separate Running Totals object
for each and every group. I'm not sure how to do this or write this
formula as I'm new to Crystal Reports and am used to SQL Reporting
Services where this evaluation is automatically done for you (I was
spoiled I guess).For example, if the Running Totals field
control is in Group #1, I want it to reset at Group #1, and Group#2 to
reset at Group #2, etc without having to create a field for each group.So
basically I'm attempting to use a formula to create a Reset point (view
screenshot for detail) that is determined by which group the data is
being calculated in. Is this possible? I realize that it is possible by
simply creating a new running total object for each group and telling
it to reset on change of group specified, but this seems completely
redundant and overly time consuming for larger reports where there are
multiple groups and a lot of Running totals fields.I'm developing the report with Crystal Reports within Visual Studio 2005 if that helps any.I
don't know if you'll be able to see it, but I have a screenshot link to
explain what I'm trying to do. http://www.codeguru.com/forum/attachment.php?attachmentid=19302Thanks!Hi Abhilash,
Thanks for the code, but the totals aren't right still yet.
Also, I just noticed my running total is not functioning properly. Count be the reason for my delima.
Any suggestions on how to get the running total to function properly?
What I just noticed is:
Date Patient Count
7/9/13 Patient A 7
8/8/13 Patient B 8
8/8/13 Patient B 8
8/8/13 Patient C 8
8/8/13 Patient D 8
8/15/13 Patient E 9
Would I be better off to do a formula vs a running total? -
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

ADF: displaying a running total, howto/code sample needed
Hi,
can anyone point me towards and example of how to display a running total on a page? I have a read only table which i want to display a total of a numeric column.
thanks in advance,
BrendenWhich technology are yoo using? JSP/UIX? JSF?
In JSF this would be easy, you can just create a backingBean for this, since you have access to the iterator in the backingbean, you can calculate any totals you want and display it on your page.
For UIX/JSP you can create a custom method on your app module to calculate your totals, and put them in the requestscope.

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. CheersHi 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:

Userexit/BAdi to run custom code on "Save" in CRM_MKTPL
Hi,
I am trying to identify a userexit or BAdi I can use to run some custom code during the SAVE event of the CRM_MKTPL transaction.
My background is mainly with ECC and I have no experience doing this in CRM. What steps are required to achieve this?
Thanks,
WillHello
I can see it by entering SE18-> Badi Name CRM_MKTPL_OL_OBJ -> Open the dropdown in the left hand pane and choose "Interface".
How did I find it? Experience, I had a similar issue, but didn't remember the name, so I went to SE18, open the matchcode and chose "information system". Since transaction CRM_MKTPL belongs to package CRM_MKTPL, I enter this as a search criteria. I found 10 hits, but only CRM_MKTPL_OL* ones sounded right to me. A little navigation and...voilà!
Sometimes, you can also run report SNIF, but it didn't help in this case.

How to trigger a custom code when user log in?
Hi my friends,
We are using multiple sharepoint sites at work. Users log in with AD accounts, so they dont see any login page.
I need to run a custom code when user login to website. Event receivers do not help at this point. Any suggestions?
thanks in advanceHi Ahmet,
From your description, my understanding is that you want to trigger some custom code when users log in SharePoint.
As a solution, you could customize a login page for your SharePoint, then you could trigger your code.
You could also use httpmodule to monitor user login. Please refer to this article about how to use httpmodule:
http://sharepoint.stackexchange.com/questions/100976/get-the-current-logged-in-user-in-sharepoint-added-httpmodule

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.
Thanks,
Katherine Xiong

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,
JoeferNot 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() -
Function MakeList(ByVal items As Object()) As String
If items Is Nothing Then
Return Nothing
END if
Dim builder As System.Text.StringBuilder =
New System.Text.StringBuilder()
builder.Append("<div>")
For Each item As Object In items
builder.Append("<div <ul>")
builder.Append(item)
builder.Append("</ul>")
Next
builder.Append("</div>")
Return builder.ToString()
End Function
Function Length(ByVal items as Object()) as Integer
If items is Nothing Then
Return 0
End If
Return items.Length
End FunctionHi Wintersbay,
According to your description, when you use the custom code in SSRS report, you got the error message.
To solve the problem, please refer to the custom code below:
Function MakeList(ByVal items As Object) As String
If items Is Nothing Then
Return Nothing
END if
Dim builder As System.Text.StringBuilder =
New System.Text.StringBuilder()
builder.Append("<div>")
For Each item As Object In items
builder.Append("<div <ul>")
builder.Append(item)
builder.Append("</ul>")
Next
builder.Append("</div>")
Return builder.ToString()
End Function
Function Length(ByVal items as Object) as Integer
If items is Nothing Then
Return 0
End If
Return items.Length
End Function

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
for I as Integer = 1 to TempVal
If(StartDate.DayOfWeek.ToString() <> "Sunday" AND StartDate.DayOfWeek.ToString() <> "Saturday") Then
TotalDays = TotalDays +1
End If
StartDate = DateAdd(DateInterval.day, 1, StartDate)
Next
Return TotalDays
End FunctionHi 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.

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.
