Invalid/blank PDF Created On Export From WinForms ReportViewer
Mar 7, 2007
I have a VS2005 C# winforms application that reads a SSRS request from a table and using the ReportViewer control produces a report and then exports in one of a number of formats via a specified path to a share on another server. This normally works without issue, however today I have had three instances of invalid or blank PDF's being produced. A sample error from the Acrobat Viewer is "There was an error processing the page. There was a problem reading this document (109)."
The software version are as follows:
Host Server: Windows Server 2003 with Sp1.
SQL 2005 with Sp1.
Acrobat reader: Version 7.0
By deleting the PDF file, resetting the processed flag to un-processed, the report was run again, and this time a perfectly readable PDF file was produced. As neither the source data nor the report definition file was updated during this time period, how it works at one time but not previously is currently inexplicable. I have run the report manually with the same input parameters using Internet Explorer and exported it successfully to another location.
Any ideas as to what is going on?
A fix to the winforms application will be to delete any existing file before exporting a new one.

Hi,
I'm developing a desktop application using CAB and DevExpress 6.3 controls. I use ReportViewer control to render .rdlc reports under local mode.
I loaded data source from a dataset, template definition from a string, called the Refresh method of ReportViewer.LocalReport, so far, all are OK. But once I call the RefreshReport method of ReportViewer, the whole Application slows down, even after I closed the report viewer form. Operations like switch between menu items, open a new form and resize the main form become double or triple slow, CPU usage is keeping in 100% while doing those operations... I've no clue how refreshing report affects all those UI drawing...
However, if I break down and jump over the RefreshReport method, an empty report form shows and every thing keeps OK.
After all, all the reports can be rendered and shown correctly finally...
And seems there is nothing to do with the templates and data source, the templates are very simple, and event if I render the reports with empty data tables, it also slows down my application.
I tried to create and run the form in a new thread, tried to upgrade to ReportViewer 9.0, but both seem useless.
Could any body help me on this problem?
Thanks in advance.

How can I add multiple rdlc report definitions to a single Winforms ReportViewer control? I would like to start with the first rdlc and concatenate subsequent rdlc files after that. I want the user to be able to scroll through several different rdlc report definitions as if they were all just one report.

I have an application built using VS 2008 (3.5 fx). I build a series of
reports (using VS 2005 (sigh)) and am now tryiing to render them using a
Windows form and the ReportViewer control in the VS 2008 app. However I
always get the error message "The source of the report definition has not
been specified" when I execute the line
m_reportViewer.RefreshReport();
When I try to view the very same report in a VS 2005 app it renders without
error. I can also view the report using Report Manager and preview it in the
VS 2005 app I use to build it. Any suggestions?
Thx
Helen

I am testing out a blank database created over two physical files on two separate disks with one table called data which has one column called values nvarchar(max).
I filled the table up with a whole load of data and ran a select * against it. If I run Permon at the same time I can see that the read load has been spread over multiple disks as each of these disks is getting read from in parallel. If I create the same database on a single file and run the same select * again it takes much longer, proving that the read load has been distributed across multiple disks.
Now moving onto writes, this is where the confusion lies. I understand that SQL server fills files evenly until they need growing, after which it will then fill files individually until they are full in a round robin fashion unless you have trace 1117 turned on. What I don't understand is why the writes aren't distributed out whilst it is filling these file groups.
I ran an continual insert into my table with go 1000000 to monitor how the files are being filled up. I monitored where SQL server was physically placing the files as they were being inserted by running the following query:
;WITH CTE AS
(SELECT
sys.fn_PhysLocFormatter (%%physloc%%) col1,
RIGHT(LEFT(sys.fn_PhysLocFormatter (%%physloc%%),2),1) AS [Physical RID],
DATAID
[Code] ....
I could see that it would a thousand or so records into file 1, then a thousand or so into file 2, then a thousand or so into file 1 etc etc. In another words it would hit one disk, then another disk, then back to disk one to fill the file evenly. Is there any way to make SQL Server distribute the writes out in parallel so that both disks are writing in tandem?
By the looks of it, multiple disks only scale reads, as with writes only one disk is ever written to at once which is annoying. Any way to harness the write power of multiple disks?

I found this method that will remove export options from a server report when called through ReportViewer. I like this one because you dont need to have a web reference to the SQL server to loop though each rendering extension. How do you call this method if for example, if wanted to remove the XML format from a particular report? I have tried ReflectivelySetVisibilityFalse("XML"), but no luck. Any clues?
private void ReflectivelySetVisibilityFalse(RenderingExtension extension)
{
FieldInfo info = extension.GetType().GetField(€œm_serverExtension€?,
BindingFlags.NonPublic | BindingFlags.Instance);
if (info != null)
{
object actualExtension = info.GetValue(extension);
if (actualExtension != null)
{
PropertyInfo propInfo = actualExtension.GetType().GetProperty(€œVisible€?);
if (propInfo != null && propInfo.CanWrite)
{
propInfo.SetValue(actualExtension, false, null);
}
}
}
}

I print 4x1 inch labels, anywhere from a few to a few thousand. It's all done from an asp.net page with a 9.0 report viewer in local processing mode.
108 Labels = 37MB or so.... this is totally unacceptable for something that when zipped becomes 1.3mb.
I thought version 9.0 was supposed to have PDF compression... Is there some kind of setting I'm not seeing any documentation for somwhere? how do i enable it?
This better not just be a server processing mode feature like the print button again... I've already taken plenty of heat from the bosses just for that alone. Try explaining the difference between a local report and a server report to your boss and then try to come up with a real world explanation as to why he can print some reports in some programs and is forced to export and printer them from adobe in other programs... please don't let me die have mercy.

Hi All,
Few days back we faced a problem when we were doing an Export to Excel of a report which was using sub-reports. After going thro. the knowledge base articles we came to know that SSRS currently doesn't suppot this option, an alternate is to use use List instead of tables, so we used List and did all the formatting with the list and the data was displayed correctly and it was Exporting to Excel also properly. But now we found out that after doing an Export to Excel, the Excel File is leaving blank rows between the data (i.e.,) If the report consists of two rows, then it displays the first row in the 10th row of excel and the second row in the 12th row of excel. The 11th row is blank and it appears as a small blank row between 10 and 12. The actual problem because of this is we are not able to do Auto filter in Excel, because Excel by default considers the values only until it encounters a blank row when we are doing auto filter. So is there a way to avoid this blank row while exporting to Excel, we have tried to remove the borders and all other stuffs but nothing seems to work. Have anyone encountered the same problem or is there any work around for this problem. Thanks in advance.

I have the multiple pages with in the report. For Example,
1. Dashboard Page
2. Risk Summary Page
3. Issues Summary Page
4. Key Summary Page
Â
I am using the rectangle for the physical page break and set the page break option as "Add a page break after" for each rectangle except for the last key summary page in the RDL
Â
Other Report details
Report Paper Size is A4, Landscape, Width = 29.7cm, Height = 21cm
Report Margins - Left=0.2cm, Right=0.2cm, Top=0.25cm, Bottom=0.25cm
Â
Rectangle size in the report body in each page as
Width=28.7cm, Height=17.5cm,
Header Height= 2cm
Footer Height = 1cm
Â
Now, the issue is when I add the Tablix with the rectangle to display the details data, it also adds the blank page after the page and when I remove the Tablix and only keep the graphs within the rectangle then blank page issue get fixed.

How to add SQl statements to the package created by Export Data wizard? I need to add SQL coming from file, the flow would be like this:
1) SQL would drop all objects: (views, tables, stored procedures) etc
2) SQL would create all objects: (views, tables, stored procedures) etc
3) Export Wizard SSIS package would execute
Also is there a dynamic way to add more tables do the package once created in SQL database? I would like to put the whole task on a scheduler too...

I built a packaage in SSIS with the import/export utility. It created a Package.dtsx and Package1.dtsx. Both of these files seem to be XML files. I want to understand how these files work. For example, in the package I built I had about 80 tables exporting and importing data. Some of them I want to allow the identiy insert and delete the rows first. Others I want to append the data. How can I find the code or settings that does this? Or where can I find the options on the gui interface to change these settings. When I search the code I can't even find a some of the tables that are being transferred.

Hi,
I have a table need to export to excel. 3 columns are 4000k. I can create the ssis package by using import and export wizard and it works fine.

(with the 3 columns created as varchar (4000) or nvarchar(4000).
I am wondering how import and export wizard can create this table which I can't create it manually?

We run std 2008 r2. I'm looking at the files this transform is complaining about.  They seem to be named appropriately. The customerid folders don't exist when this runs. I'm going to put one in place to see if that is the problem.
The errors i'm getting are...
[Export Column [22]] Error: The file name "c:usersmyuserid heprojectnamecustomeridafilename.doc" is not valid. The file name is a device or contains invalid characters.
[Export Column [22]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Export Column" (22)" failed because error code 0xC020207F occurred,
and the error row disposition on "input column "FILENAME" (29)" specifies failure on error. An error occurred on the specified object of the specified component.Â
There may be error messages posted before this with more information about the failure.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Export Column" (22) failed with error code 0xC0209029
while processing input "Export Column Input" (23). The identified component returned an error from the ProcessInput method. The error is specific to the component,but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.

trying to get a new database created then running a script to created the tables, relationships, indexes and insert default data. All this I'm making happen during the installation of my Windows application. I'm installing SQL 2012 Express as a prerequisite of my application and then opening a connection to that installed SQL Server using Windows Authentication.Â
E.g.: Data Source=ComputerNameSQLEXPRESS;Initial Catalog=master;Integrated Security=SSPI; Then I run a query from my code to create the database eg: "CREATE DATABASE [MyDatabaseName]".
From this point I run a script using a Batch file containing "SQLCMD....... Myscriptname.sql". In my script I have my tables being created using "Use [MyDatabaseName]   Go  CREATE TABLE [dbo].[MyTableName] .....". So question is, should I have [dbo]. as part of my Create Table T-SQL commands? Can I remove "[dbo]."? Who would be the owner of the database? If I can remove the [dbo]., should I also remove dbo. from any query string from within my code?

Hi all,
Am I right in my understanding that I cannot deploy SQL/e to a machine that isn't running Visual Studio 2005, if I'm trying to ship within a winforms app?
Is this being fixed in the final release, or RC1?
What timeline is there for the release of SQL/e?

I'm new to SSRS. I would like to launch a report from a C# desktop application, supplying parameters programatically. I was able to do this using System.Diagnostics.Process p ... then p.Start(@"(path)iexplore.exe","(reportURL)"); I'm betting there's a much better way to do this.
Ideally I would like to create an IE window that shows only the report, that is, only the report viewer toolbar is visible, the IE toolbars and menus are hidden. I want to specify IE as the browser in case some other browser is installed as the default web browser.
Can anyone link me to a tutorial or provide a code snip? Thanks.

Hi,
I am trying to connect to a remote SQL Server 2000 database using ASP.NET. This is my connection string
"Server=LOL-DEV;Database=Livelink;User ID=sa;Password=xxx;Trusted_Connection=False"
With this I get 'access denied or sql server doesn't exist'. If I use exactly the same code in a WinForms app, the connection works OK.
Does anyone have any idea why this might be?
Cheers

We are thinking of using a Sql Server Express database (.mdb.mdf) as a data resource in a Windows Forms application that we will be distributing to clients. When the application is built, the mdb file is copied to the bin directory.
In order for clients to access this database, will they need to have an instance of the SQLEXPRESS server installed on their computer? Or since the .mdb.mdf file is being accessed from a .Net 2.0 application, there is no need to install a separate db component?
If I do have to separately install the db component on the client end,
is this the way to go about it? This? Or is there a different/better way?

Hi,
I have a Visual C# WinForms app which I am accessing a SQL Server 2005 database with. On the Server, I have allowed remote connections (TCP and named pipes) and enable SQL Browser as per instructions on MSDN. The app works fine on the development machine.
Server name is <machine name>SQLEXPRESS, connecting with Windows Authentication.
Server log states that it is listening on [ 'any' <ipv4> 3153].
Server named pipe provider is ready to accept connection on [ \.pipeMSSQL$SQLEXPRESSsqlquery ].
On the client (local network), when trying to open the database I get this error still:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Also on the client, I can go into the ODBC Data Source Administation, and connect to the SQL Server Database that way successfully.
What further steps can I take to allow the client to access the SQL Server?

Hi
I create a small aplication to lookup postal codes, it uses only some basic queries. It's a Winforms (using Visual Studio 2008) application, as MS put as local datase SQL Server Compact 3.5, I use it.
The application works fine it has only tree tables (with the postal codes of USA, Canada and Mexico) using the SQL Server Compact 3.5 database file.
I create a setup project and made and installer, in this case I follow the indications from MS to copy to the application folder alld the SQL Server dll files needed.
In Windows XP, the aplication works fine after installation. But in Windows Vista not. I found that as the installer put all files unde C:Programa filesMy CompanyPostal Codes folder, the application need's administrator permission to run.
I don't know how to change the database file to another location in order to avoid this problem.
Do you know how to avoid this? Maybe using a different path for my database file (if this can you tell me how to make the connection string to works properly) Or making the app to requires the administrator permission (I know tha in VS 2008 this can be done, biy not idea of how?
Thanks for you valuable help.

Hi all,
I've finally received my first official assignment using vb.net and SQL Server.
I have been developing / learning with both on the express editions.
I've also just run into some issues trying to access a SQL Server 2005 Express .mdf thru
SQL Server 2005 Pro.
We just couldn't get it to open. Connecting or Attaching etc...
We had to install SQL Server Express on the other PC to get it to open the SQL Server 2005 Express .mdf.
---
Now that I am ready to develop in ernest, I would like to setup my own controlled development environment.
Our target is a winforms application with a SQL Server 2005 Database for WinXP or Vista.
I'm ready to purchase Visual Studio 2005 Pro once I figure out the best development environment and SQL Server Version.
Specifically, once I've developed my winforms app, what issues do I need to consider to install a SQL Server 2005 database server / engine on a client / users machine?
Can I use the SQL Server 2005 Express?
Or perhaps there is an MSDE equivilant for 2005?
I can't seem to find any info regarding installation procedures for SQL Server in this regard.
(Perhaps its because I'm using the express editions?)
Any positive contructive help would be greatly appreciated.
Thanks,

Hello,
I've got the following query:
SELECT zA."ID" AS fA_A
, zA."TEXT" AS fA_B
, (
SELECT COUNT(zC."ID")
FROM Test."Booking" AS zC
) AS fA_E
FROM Test."Stack" AS zA
WHERE zA."ID" = ?
With this query I call:
- SQLPrepare -> SQL_SUCCESS=0
- SQLNumParams -> SQL_SUCCESS=0, pcpar = 1
- SQLDescribeParam( 1 ) -> SQL_ERROR=-1, [Microsoft][ODBC SQL Server Driver]Invalid parameter number", "[Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index"
Is there a problem with this calling sequence or this query? Or is this a problem of SQL Server?
Regards

I've installed sql server 2005 on a customer's machine.
I have a very small "connection tester" app C# (2005) winforms app, which I use to verify connection strings. This app has been working for years. I am using the sa account to login with in this test app just to keep things simple. I am using Sql Server Authentication.
When I try to connect, I get a "login failed for user sa". I'm absolutely certain that I have the password correct.
Sql Server Express is setup in mixed mode, and I have all the tcp/ip settings correct ( as far as I know ).
I think if it was a tcp/ip thing, it wouldn't find the machine, as opposed to saying Login Failed.
I'm running out of things to look at.
The machine has .NET 3.5 installed. The connection test was written using C# 2005, .NET 2.x Could that cause a problem?

We have a winforms application with local rdlc reports. Â On Surface Windows 8 Pro devices only, reports render such that they are scaled down and don't fill the page. Â If resolution is lowered on the device, the report scales up to fill the page.
 This affects the appearance in print layout and well as the actual printed size.
If we export to pdf, it renders to fill the page (as expected). Â If you print to pdf or to printer, the scale is shrunken.
If we change the resolution settings so that "Make  text and other items larger or smaller" is set to small, the issue is resolved except the tablet is not very usable on this setting.Is this a bug?
