Define Printer In Report
Apr 17, 2007I have a client who tells me in Access you could assign the printer directly to the report using PrtDevNames and PrtDevMode. Apparently it's true.
Can this be done in Reporting Services?

The code below is a class file done in vb.net. The original idea came from reading this forum and some blogs.
To use the code below, you can create a windows application or service.
then create a class file and drop this code in it.
Remeber to reference the 2005 report execution service and also in the program settings include the path to your server.
IE: ReportExecutionService = http://localhost/ReportServer/ReportExecution2005.asmx or whatever your server URL is at.
Setup the public properties for printername (sharenames work fine), Number of copies and Report name.
That is all there is to it. This code is REALLY expandable to add more options.
Please remember to let me kow if you like this.

Hello,
I am trying to get a SSRS 2005 report to print from my Visual Studio 2005 C++ application without using the ReportViewer to preview it first. What I have done is created a dll that I call into when I want to access a certain report and print it. While searching around on the internet I found an MSDN article about printing a report without previewing and it had an example in C# code. So I used that as a guide for my C++ code but I am still having problems with rendering the report properly so it can be printed. When I try to render a report using the "Image" format, my streamid string is empty but the byte array that the render routine returns is not. Here is the code I am using, what could be the problem here?
Note: m_Streams is define elsewhere as
array<String^>^ m_Streams = gcnew array<String^>(10);
void Print::Export(LocalReport^ report)
{
array<Warning^>^ Warn = gcnew array<Warning^>(10);

" <OutputFormat>EMF</OutputFormat>" +
" <PageWidth>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0.25in</MarginTop>" +
" <MarginLeft>0.25in</MarginLeft>" +
" <MarginRight>0.25in</MarginRight>" +
" <MarginBottom>0.25in</MarginBottom>" +
"</DeviceInfo>";
String^ mimeType;
String^ enc;
String^ FileExt;
array<Byte>^ bytes;
bytes = report->Render("Image",deviceinfo, mimeType, enc, FileExt, m_Streams,Warn); // m_Streams has a length of
return; // 0 after the Render
}
void Print:: PrintPage(System:: Object^ sender, System:: Drawing:: Printing:: PrintPageEventArgs^ ev)
{
Metafile^ pageImage = gcnew Metafile(m_Streams[m_CurrentPage]);
ev->Graphics->DrawImage(pageImage, ev->PageBounds);
m_CurrentPage++;
ev->HasMorePages = (m_CurrentPage < m_Streams->Length);
return;
}
void Print:rintRpt()
{
String^ printerName = "Default";
if (m_Streams->Length < 0)
return;
PrintDocument^ printDoc = gcnew PrintDocument();
if (!printDoc->PrinterSettings->IsValid) {
return;
}
printDoc->PrintPage += gcnew PrintPageEventHandler(this, &Print:: PrintPage);
printDoc->Print();
return;
}

{

LoadData(ds);
report->ReportPath = "c:\bmi\bulrpt\Report1.rdlc";

RDS->Value = ds->Tables["Subject"];
report->DataSources->Add(RDS);

return;

i need to set Printer Delivery Extension, and create a subscription for report which will be sent to the printer automatically
I have created a report that displays a limited number of rows and columns when called as a sub-report. If the report is called directly, all rows are returned and all columns are shown. I would like to control how large the report is (BodySize) when called as a sub-report as not all columns will be shown. This sub-report is part of a dashboard where several other sub-reports are also shown, so reducing the size is important. I hope to avoid the need to have a version of the report when called from the dashboard and also a version when called in expanded mode.
Dear ppl,
I got a Report Model Project, in which i have created a model of my Database and deployed it on the server...
Then I have a Report Server project for my reports. The reports are using Report Model as the DataSource...
Now in the Report Designer, inside a report, when I define query for Dataset using Report Model , I can't find a way to write a left Outer Join query... It always performs Inner Joins... was wondering ether Report model supports Outer Joins ?... I might achive this using two different datasets but then i'll end up using two data regions e.g. 2 tables, but i don't want to do that... instead I want all of my data to appear in a single table which can reference to single dataset.
Is there a way to define left outer joins using Report model ? I am new to this Reporting Servces and I might be missing something here... would any body please point out that
I have a report which will one day display some data from an analysis services cube. my first step is to create a drop down parameter enabling the user to choose the date. I'd like to display only dates that have data, and I'd like it to default to today.
So I've created a dataset that will be the datasource for the dropdown displaying the available non-empty dates, which works fine.
SELECT measures.turnover ON COLUMNS,
nonempty([TBL DIM DATE].[DATE_ONLY].[DATE_ONLY].ALLMEMBERS ) ON ROWS
FROM [Itdev1 Hk]
I've also set the report parameter up to be a queried paramter,and to use the above dataset as it source, with [DATE_ONLY] displayed. and [DATE_ONLY] as the value.
Now, how do I get it to default to the last valid member in the list?
Can someone please explain how i would define a multi-valued default parameter within the report Properties -> Parameters. I have an OLAP based report with multi-value parameters. I do not want to set the default values from within BIDS. Instead, I'd like to do this from the ReportServer (after report deployment). I have no problem when i enter a single value as a 'default value', for example:
ReportParm1 String [Deal Dim].[Shelf].&[AAM]
But, how would i define it with multiple values as a 'default value' ?, for example:
ReportParm1 String [Deal Dim].[Shelf].&[ABC] , [Deal Dim].[Shelf].&[DEF]
NOTE: It appears that you cannot use expressions, such as the 'split' function in the 'default value' space.
Any help would be greatly appreciated.
thank you.

View 2 Replies View RelatedI am trying to modify the Printer Delivery Sample (RS 2005).
The original sample works fine: there was no any problem with deployment and running it.
What I need to accomplish is saving each delivered report as a local XML file.
For now (to start with), I'm just trying to read the rendered report as XML, and write the string (whatever the report contains) into a text file.
I added the following code to the PrintReport(...) method in the PrinterDeliveryProvider.cs file:
deviceInfo = String.Format(
System.Globalization.CultureInfo.InvariantCulture,
@"<DeviceInfo><OutputFormat>{0}</OutputFormat></DeviceInfo>",
"xml");
RenderedOutputFile[] testFiles = notification.Report.Render("XML", deviceInfo);
using (FileStream fs = File.Create(@"C: est est.txt"))
{
using (StreamWriter sw = new StreamWriter(fs))
{
sw.WriteLine("******************");
try
{
Stream streamTemp = (Stream)testFiles[0].Data;
byte [] byteData = new byte[streamTemp.Length];
for (int i = 0; i < byteData.Length; i++)
{
byteData[ i ] = (byte)streamTemp.ReadByte();
}
using (MemoryStream ms = new MemoryStream(byteData))
{
string result = Convert.ToBase64String(ms.ToArray());
sw.WriteLine(result);
}
}
catch (Exception ex)
{
sw.WriteLine(ex.Message);
}
sw.Flush();
}
}
After I re-deploy the modified assembly and create a simple subscription, it fires, and there are no exceptions. But instead of some good-looking XML in the test.txt file, I get this:
******************
///////////////////////////////////////////////////////////////////////////////////////////////////////////////
[Actually, there are much more slashes, but I am showing just the beginning of the file - for brevity...]
When I run this report in ReportManager and export it as "XML file with report data", that XML exported file looks exactly as I expect it to. So, the data is there, in the report, but how do I extract it?
I've been trying to figure out why I am not getting the real content of the report in XML format.
Maybe, this line is wrong: RenderedOutputFile[] testFiles = notification.Report.Render("XML", deviceInfo);
AND/OR this line is wrong: deviceInfo = String.Format(................etc.
AND/OR I am using a wrong method for converting the Stream to a string.
...or, something else?
Could someone kindly help me figure out what I'm doing wrong, please?

I believe this is an extension of the problem described here:
http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=115351
The service pack for Visual Studio has fixed the problem when I print my report from VS, however when I deploy and print my reports from the SSRS website they are still incorrect.
My SSRS server is running SQL 2005 with service pack 2 installed and the 9.00.3152 9333097 Cumulative hotfix package (build 3152) for SQL Server 2005 Service Pack 2 also applied.
I find it hard to believe the problem was fixed in the developer tool but NOT in the client tool?
How can I develop reports when the output from the developer tool is different to the output from the client tool?
For example I specify a box to be 5cm wide, and when printed from visual studio it is 5cm wide, but when printed from the SSRS website it is not 5cm wide!
Thanks.
Very strange problem here with Reporting Services SQL 2005 SP1 with latest patch KB 918222 on Windows Server 2003 SP1. The clients PC are Windows XP both SP1 and SP2 and that's not affecting our problems.
When my default printer is set to the "Printer 1" (HP LaserJet 9000), when i look a report's into the Report Viewer and i click on the print button (printer image button that use the ActiveX RSClientPrint), i let the default printer to "Printer 1". In this case, the report is printed correctly.
Again with my default printer set to "Printer 1", i look the same report into the Report Viewer and i click on the print button again. This time i select another printer "Printer 2" (an older HP LaserJet 8000 DN) and the report is printed correctly.
Now the problem is when i set the "Printer 2" as default printer. If i go to the Report Viewer and i click on the print button for the same report that was printed correctly before, now the report seem's to be ok into the preview before i print, but when i send the job to the "Printer 2" the report require a unknown paper format, so the "Printer 2" ask paper into the tray 1 (manual feed) and the result of the printed report is not good. The right and the bottom seem's to be cutted. I tried to reduce the report dimension without good results. The report is always cutted to right and bottom and the printer ask paper into the tray 1 (unknown paper).
Is't not the end, if i print the same report on the "Printer 1" when the default printer is "Printer 2", the report is printed correctly.
I have tried to use another printer than the "Printer 2" to see if the problem is the printer. I tried the "Printer 3" (HP LaserJet 9050) as default printer, i print the report on this one and i have the same problem than with the "Printer 2". And if i set "Printer 1" as default and i print on the "Printer 3" the report is printing correctly.
For all the printers i have the latest drivers. The same problem is occuring on all other PC other than mine.
We have checked the printers configuration and all seem's to have the same configuration.
Can this be a bug with the ActiveX RSClientPrint or what ?
Note that all previews before printing are good with all printers, but with the "Printer 2" and "Printer 3" set to default, the printed report was not the one i saw into the Preview.
Below a link to a sample report that we have. All our reports have the same global dimensions.

My company has a .Net app that embeds the reportwriter for displaying (and printing) reports. This seems to work fine visa vis printing reports in landscape mode, although odly if you look at the printer properties it SAYS it is priting in portrait. In any case, the problem comes when this default reportwriter isn't used but rather an rdl file is generated programmatically. No matter what width and height settings we use, the document unfailingly prints in portrait mode. I've looked to see whether there is any way to force the printer mode, but it seems there isn't, at least not through an rdl. Or what SHOULD work (setting the width larger than the heigh) does not. I'm wondering if anyone else here has run into difficulties like this if there are any solutions or places I might look for answers? Thanks!

Now I am duplicating the CTE definition inside each if condition. But I expects a solution like bellow to reduce code duplication.
For example
---- I need a common definition of CTE like this.
with CustomGroup( id)
as
(
Select id from Groups g
Inner join GroupStatus s on s.Id = g.Id
Where s.Status = €˜Active€™
)
IF @DisplyStatus=€?UserDetail€?
begin
<!--[if !supportLists]-->- <!--[endif]-->at present CTE is defined here.
select u.* from users u
inner join userGroups ug on ug.UserId = u.Id
inner join CustomGroup cg on cg.Id =ug.GroupId -- Accessing the CTE
end
else if @DisplyStatus=€?UserSimple€?
begin
<!--[if !supportLists]-->- <!--[endif]-->at present CTE is defined here.
select u.FirstName,u.LastName,u.DOB from users u

Hi, here am i back ..not sure it's possible to solve it in one query ...there are four tables:1) headquarters---------------hqID (primary key)hqname2) department---------------depID (primary key)depnamehqID3) reports----------repID (p. key)depIDuserID4) users--------userID (p.key)usernameI want to get in one query those four fields:hqID, hqname, depID, depname + varchar(number of distinct users that has made a report foreach department) . This last field is a concatenation.The complexity resides in the fact there is need for a COUNT among other fields ...E.g.: table reports may look like this: repID depID userID 1 1 1 2 1 1 3 1 3 4 3 6 5 4 8This gives:for dep 1: 2 distinct usersfor dep 2: 0for dep 3: 1 distinct userfor dep 4: 1 distinct userThanks for helpTartuffe
