hi
i am getting an error with my code, it says 'value of type byte canot be converted to 1 dimensional array of byte' do you know why and how i can correct this error, the follwoing is my code.
can anyone help me correct the error and let me know ow to solve it
thanks for any help givenPublic Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequestDim myConnection As New Data.SqlClient.SqlConnection("ConnectionString")

Hello, I am using .net 1.1 and sql server 2000.
I want to store a byte array, but it seems that only a string is stored there.
Code:
SHA512 sha = new SHA512Managed();
byte[] ReturnedPasswordByte = sha.ComputeHash(ToCryptByte);
MyGenericCommand.Parameters.Add("@Password", ReturnedPasswordByte);
MyConnection.Open();
MyGenericCommand.ExecuteNonQuery();
MyConnection.Close();
If I select the record later, all I get is "System.Byte[]" (as string)

I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

Hi people,I have a little problem with this!There are some variables in C# code: int personID = 10;
string personName = "Tom";
System.IO.BinaryReader reader = new System.IO.BinaryReader(FileUploadPersonPhoto.PostedFile.InputStream);
byte[] personPhoto = reader.ReadBytes(FileUploadPersonPhoto.PostedFile.ContentLength); After that, there is a SQL query: string query = "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES ("
+ personID + ", '" + personName + "', " + personPhoto + ")"; In Debug mode, value of the query is "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES (10, 'Tom', System.Byte[])" and it does not work! Is there any prefix or something else that I should put and make it work?Thank you in advance!P.S. Do not want to use sql parameters at this piont!

I have a binary column with length 20 in SQL server table. I store dynamically C# byte[] value range from 0 to 19. So for example, If I store length of 16 and when I try to retrive it back into byte [] in C# it returns whole length 20. When I see in debug it has value from 0 to 15 which I want to use but from 16 to 19 is zero. How can I get just length value which I stored.
I use DataRow to get whole row and from the row object I extract byte [] based on column name.
Thank you in advance....

Hello,
I need some help working with CLR UDTs. I have created two UDTs called trajectory and point. Each trajectory consists of a list of points. Each point consists of three members : lon( type double), lat( type double) and datetime.
I have written my own IBinarySerialize.Write method for the trajectory type which is the following:
Dim maxSize As Integer = 4000
Dim value As String = ""
Dim paddedvalue As String
Dim i As Integer
Dim pt As Point
For i = 0 To point_list.Count - 1
pt = point_list.Item(i)
If i = 0 Then
value = value & pt.X & "|" & pt.Y & "|" & pt.D
Else
value = value & ">" & pt.X & "|" & pt.Y & "|" & pt.D
End If
Next
paddedvalue = value.PadRight(maxSize, ControlChars.NullChar)
For i = 0 To paddedvalue.Length - 1 Step 1
w.Write(paddedvalue(i))
Next
If I try to store 225 points for a trajectory then the following error occurs:
System.Data.SqlTypes.SqlTypeException: The buffer is insufficient. Read or write operation failed.
Why is that happening? The limit size for a UDT is 8000bytes. Each point needs 24Bytes (2*SizeOf(double) + sizeOf(Datetime)).
Please help

I have a bigint column called "MillisecondsSince1970" that I need to convert to a date - SSIS is erroring out when I use DATEADD with the 8 byte int (if I use 4 byte it works but the column is bigger than 4 byte). The error is really lame:
[Derived Column [79]] Error: The "component "Derived Column" (79)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "Date" (100)" specifies failure on error. An error occurred on the specified object of the specified component.
Anyone have a way around it... a VB.NET equivalent of DATEADD or something else I can do?

Experts,
i have trouble while insert/update a field which contains double-byte characters (Chinese Traditional).
NO PROBLEM if i m using Enterprise Manager to view/edit the data. They are retrieved properly in the following:
(1) Enterprise Manager
(2) Query Analyzer
(3) Visual Basic
(4) Command prompt isql
EACH of the Chinese words are become a qustion mark '?' if the UPDATE SQL or stored procedure executed in the following:
(2) Query Analyzer
(3) Visual Basic
WHILE (4) Command prompt isql does not have the problem for the same UPDATE SQL and stored procedure.
Do you have any idea?

I want to store some double byte characters in a table. Originally I planed to change all data type of fields which will store double bytes from VARCHAR() to NVARCHAR(). But i just found out we have no problem to pull and store foreign content(double byte characters) in fields with VARCHAR type( the content is showing correct after stored in database)
my question is : if VARCHAR can handle double byte character, what's the point of using NVARCHAR to store unicode character? any advice is appreciated.

Hi,
Just wondering if anyone knows if you can create a certificate from a byte[]. For example, you can create an assembly using CREATE ASSEMBLY FROM 0x...; specifying the hex representation of it - can you do the same with a certificate? This means that you don't need to save the file to disk before loading it into the database.
Cheers,
Adam

Hello, I'm having users upload documents to my db and storing them as an Image datatype, I can do that without an issue. I'm also able to find that record and return it as a byte(). Now, what's the best practice/scheme to return it to the browser, even FF, and have it prompt the user with the Open or Download thing Dialogue we all know and love.
Thanks in advance.

I've created a DTS package -- that uses a query to export to a .txt file. My question is -- if the results of this query are zero (no results returned within the package ) -- how can I tell the package not to export a zero byte file. Any thoughts on that? Any help you could give would be greatly appreciated. Thanks!

I'm having trouble adding a 4-byte integer with an 8-byte integer. Here's what I'm doing:
Column Name: BIG_ID
Derived Column: < add as new column >
Expression: (DT_I8)[ID] + 840230000538058
Data Type: eight-byte signed integer {DT_I8]
The error I get:
The literal 840230000538058 is too large to fit into type DT_I4. The magnitude of the literal overflows the type.
Then I try the expression:
(DT_I8)[ID] + (DT_I8)840230000538058
and
[ID] + 840230000538058
and get the same error.
What am I doing wrong? Is it possible to add 2 8-byte integers in regular expression? Why does it still think the literal is DT_I4?
Thanks,
Michael

Hi, I'm a bit new to DTS but the problem I have encountered relates to importing a text file. On occasion the file is zero bytes which causes an error in DTS. I have added some VBScript to the workflow to check the filesize. If size > 0 then I set Main = DTSStepScriptResult_ExecuteTask otherwise Main = DTSStepScriptResult_DontExecuteTask. This all works fine except that when the file is 0 the dependent process that is waiting for completion/success does not run, presumably because the task was not run (as reqd). I have tried setting the status rather the DontExecuteTask but then the task runs anyway creating the error. Anyonw know how to get this to work or how to get around the problem?
regards

Hi,
I have a text file (5 MB). It appears as a single line in a text editor. But actually it has records of 1500 byte length each.
I want to strip it down to 1500 byte records. So 1500*3500 = 5 MB (approx). The record size is always 1500 bytes.
Does anyone have a script that I can run on this file to achieve this break.
Thanks

For example:

when the length is more than 4000 ,the data in the behind will be lost

Hi,I have a .NET application that I want to save the Config.EXE contentsto my SQL database for remote review/testing. This config file is3700+ bytes long. I created a field in one of my tables with a VARCHAR4800 and then created a stored procedure that receives a parameter(also VARCHAR(4800).However it fails to write anything if the length of the value that Ipass is anything greater than 900. If I pass exactly 900 characters orless - the data is written to the field. If I pass 901 characters Iget nothing.I'm suspicious since it is exactly 900. I seriously doubt it's somelimitation of MS-SQL so I need a nudge in the right direction.Thanks

I have an Excel spreadsheet that I eventually land into my staging table. In between, I'm attempting to get a date code from the Date table. I'm using a Lookup Transformation Editor and mapping the fiscal week of year and fiscal year name. I know the fiscal year name is fine. When I have both the fiscal year name and the fiscal week of year, the package fails on the lookup step. In a data conversion, I convert the fiscal week of year to a single byte unsigned integer. (In the Date table, the fiscal week of year is a tinyint.) I'm not sure what I'm doing wrong?

My problem is that i can't search a field that contains Asian characters (Korean in this case).
The table user_Access_tab have 2 keys:
access_id nVarchar(50)
user_id nVarchar(50)
The sql query below is sent through a oledbcommand to a sql server 2005 database.
"select access_id, access_right from user_Access_tab where user_id ='HQ001kimjo012007-05-07 ì˜¤ì „ 11:50:323401'"
It doesn't show any hits even thogh i know there is a number of matching records.
The question doesn't generate an answer in SQL server manager studio eigher.
If i change the datatype on user_id to Varchar(50) the id is presented (in the database) as:
HQ001kimjo012007-05-07 ?? 11:50:323401
Then the question works, but why doesn't it work with nVarChar(50)?

Hello all,
I was trying to run a test to write a ebcdic file out with a comp - 3 number (testing this for other people) and have run into a problem writing the string out to the flat file destination. I have the following script component:
Code Block
' Microsoft SQL Server Integration Services user script component
' This is your new script component in Microsoft Visual Basic .NET
' ScriptMain is the entrypoint class for script components
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Public Class ScriptMain
Inherits UserComponent
Public Overrides Sub CreateNewOutputRows()
'
' Add rows by calling AddRow method on member variable called "Buffer"
' E.g., MyOutputBuffer.AddRow() if your output was named "My Output"
'
Output0Buffer.AddRow()
Dim myByteArray() As Byte = {&H12, &H34, &H56, &H7F}
Output0Buffer.myByteStream = myByteArray
Output0Buffer.myString = "ABCD"
Output0Buffer.myString2 = "B123"
myByteArray = Nothing
End Sub
End Class
I have added myByteStream as a DT_BYTES length 4, myString as (DT_STR, 4, 37) and myString2 as (DT_STR, 4, 37) to the output 0 buffer.
I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width.
When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following:
Code Block
[Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems.
NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.

I'm running into a problem where if I have over a certain byte size or number of parameters being passed into my stored proc I get an exception that reads: "Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized." If I remove one parameter, the problem goes away. Has anyone run into this before? Thanks,Mark

I need find out the number of columns in flat file before i process that particular file.
I have file name in @filename variable and file path is @filepath variable.
But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles
And I am using for each loop container to read the file one by one and put the file name in @filename variable.
and my file name like
Product_20120607060930.txt
Product_20130708060930.txt
My file structure is:
ID,Name,City,Country,Phone
1,Riya,Pune,India,454564
2,Jiya,New Jersey,India,454564
3,Riya,St Louis,USA,454564
4,Riya,Belleville,USA,454564
5,Riya,Miami,USA,454564
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file. if it is not there then i have to send mail to client saying that file is not valid.
Let me know how i will do it.I need to also calculate the size of flat file.
