Filter Data using parameters (in vb.net)

I am trying to use reporting services with vb.net. Since there is no EASY way
to pass dataset to the reporting services (i understand until Vs.net2005). As
an alternative below is what I am thinking of.
I am using vb.net and trying to dynamically generate the SQL to control the
filter. In the initial report definition I have the base SQL get a large set
of data and filter the data within the report format.
How do i pass filter the report data by using parameters. Has anybody got
any sample code?
I have checked the available paramters and what they are supposed to be used
for. They are:
rs prefix (which uses the Command, Format, Snapshot paramters)
rc prefix - i.e type of format
Not sure how I can use the existing parameters so that I am able to filter.
Please help,
Rgs,
MehulI just had a similar issue, I was returning a large set of data for a graph,
and wanted to use the same data to show only a single row, so I put a table
and filtered the data based on the parameter passed into the report.
1.) add the table
2.) set upt he rows and headers to show
3.) click on table and select properties
4.) click filters
5.) in left column, select the field name that you want to filter on
6.) in second column choose relationship
7.) in third columns, select expression, then choose parameters from the
tree and select the actual parameter to filter based on
8.) the filter looks something like Fields!filedName.Value =Parameters!parameterName.Value
you may have to explicitly cast these both to ints
CINT(Fields!filedName.Value) = CINT(Parameters!parameterName.Value)
And at this point, you have your form element showing only data that matches
the parameter that was passed to the report.
Hope this helps

FileUpload

I have gotten FileUpload in VB.Net to work fine in saving a file to a web server folder but cannot find some examples on how to save the file as an image on sql200. Can anyone point me in the write direction - thanks.

Please refer to this article, which contains a sample about how to deal with BLOB data in SQL Server:
http://forums.asp.net/thread/1254026.aspx

|||

i dont like it, but i figured it out and have written about in my blog

http://weblogs.asp.net/hpreishuber/archive/2006/02/17/438498.aspx

|||

string fileName = FileUpload1.PostedFile.FileName;

byte[] lc_ByteFile = new byte[FileUpload1.FileContent.Length];

lc_ByteFile = ReadFileToByteArray(fileName, FileUpload1.FileContent.Length);

if (FileUpload1.FileName.EndsWith(".jpg") || FileUpload1.FileName.EndsWith(".jpeg") || FileUpload1.FileName.EndsWith(".gif") || FileUpload1.FileName.EndsWith(".bmp"))

{

System.Drawing.Image newImage;

MemoryStream stream = new MemoryStream(lc_ByteFile);

newImage = System.Drawing.Image.FromStream(stream);

newImage.Save("D:\\NewImage.bmp");

}

Try this out it works

Files in SQL 2005

Hello,
In my ASP.NET 2.0 web site I need to upload many files to various
folders and add the information in an SQL 2005 database.
I am creating a documents table which includes the fields:
[DocumentId], [DocumentAuthor] and [DocumentUrl]
This table will have records for many files.
Is there a standard way to name the files?
Maybe renaming the files to "doc" + DocumentId?
However my DocumentId is a Guid so it would be to big ... I think.
I would need to create the record, get the DocumentId and then access
the record again to add the DocumentUrl after renaming the file in
my .NET code.
Anyway, is there a standard way to make sure that every file name is
unique and that at the same time won't have an unreadable name?
Thanks,
Miguel

File Upload to SQL in 2.0 VB

Can anyone give me an example of how to Upload a file to SQL in asp.net 2.0 using VB?

Thanks

Randy

The way i do it is with a table of 3 columns:

ImgSize(int)
ImgContentType(nvarchar)
ImgFile(image)

Code:

'Pic is a File Upload Contol

Dim cnn As New SqlConnection(strConn)

Dim imgStream As Stream = Pic.PostedFile.InputStream
Dim imgLen As Integer = Pic.PostedFile.ContentLength
Dim imgContentType As String = Pic.PostedFile.ContentType

Dim imgBinaryData As Byte() = New Byte(imgLen) {}
Dim n As Integer = imgStream.Read(imgBinaryData, 0, imgLen)

You then build your command object and set your parameters with
the value you got above (imgStream, imgLen, imgContentType) and
then execute an non query.

Let me know if you need help reading as well !

|||@.amensi: ei that's the same problem as mine! So that's it, but if you don't me asking, can that also upload a MS word text file? if it doesn't can you please post the source code and where to put it? thanks!

File Protection

Hi -
I'm building a VB.NET application using an MSDE database. I'm working on an
install program for the app, and I'm running into an error with the MSDE
install.
I'm installing MSDE by executing the MSDE setup:
setup.exe INSTANCENAME="test601" BLANKSAPWD=1
DATADIR="d:\data\test601\Data\" TARGETDIR="d:\data\test601\"
DISABLENETWORKPROTOCOLS=0 SECURITYMODE=SQL /L*v
"d:\data\test601\MSDE601.log"
The install works without error on my WinXP Pro development machine. But I
get a Windows File Protection error on a 'fresh' WinXP Home computer.
I create the WinXP Home environment by installing WinXP Home from the MSDN
DVDs and then applying all of the Windows Updates from the MS site (except
for SP2; I'll test that one separately). I then install MSDE by running the
above setup, and I get the following Windows File Protection error:
"Files that are required for Windows to run properly have been replaced by
unrecognized versions. To maintain system stability, Windows must restore
the original versions of these files. Insert your Windows XP Home Edition
CD-ROM now."
How can I prevent this error message from appearing? (MSDE appears to have
installed fine, other than displaying this error.) Or, perhaps more
importantly, how can I install MSDE in a way that does not threaten "system
stability?"
Thanks for your help.

|||Thanks for your response -
While it may be true that a virus was at work here, I was able to get a
different cause ("known issue") from MS (see below). Just curious: what
virus did your computer have?
- Jeff
Response from MS:
I found that it turned out to be a known issue in MSDE setup or SP3a Setup
that File Protection will pop-up . The root cause is the protected system
file sqlunirl.dll was not restored to its original, valid version because
the Windows File Protection restoration process was cancelled by user
interaction. However on computers with Windows XP SP1 if the dllcache
folder is missing or the contents of the dllcache are empty, then you might
still get the pop-ups even with sp3a.
First of all, upgrade your Windows XP to the latest MDAC 2.8
Microsoft Data Access Components (MDAC) 2.8
http://www.microsoft.com/downloads/d...fe3-c795-4b7d-
b037-185d0506396c&DisplayLang=en
Secondly, if above doesn't work, the workaround for this issue is
1. First manually run the dahotfix.exe, which will install/copy the correct
copy of SQLUNIRL.DLL (2000.80.728.0) into the dllcache. (I got the
dahotfix.exe from the sqlredis.exe that ships with SQL2KSP3 in the
x86\other folder. Just right click on this sqlredis.exe and extract the exe
to a local folder. This will give you mdac_qfe.exe. Then again, right click
on mdac_qfe.exe and extract the contents of this exe into another local sub
folder. This should give you a dahotfix.exe)
2. Then run the setup, which should complete successfully with no errors.

File permissions

I've been having problem in my asp.net 2 web when using the "User Instance=true" style connections to databases.

I would get ASP.NET event log errors like this:
Exception information:
Exception type: SqlException
Exception message: An attempt to attach an auto-named database for file c:\temp\dnn\dnn\dnn455\App_Data\Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

After I used ProcessMonitor it showed that the user ASPNET was trying to access C:\ directly after trying to open the database.mdf file I wanted open.

I had to give the ASPNET account read/execute permission to c:\, which was very scary.

Could someone please enlightenment me as to the correct file permissions needed to use databases in user instances?

Thanks,
Alex

You have the option to connect the User Instance to Management Studio because of known issues with User Instance. Try the link below for details.
