I'm trying to read a byte array of an image datatype from sql server, and then to put this in another field in the database. I get a byte array, but somehow the image doesn't get into the db well with the sql parameters. Does anyone have an idea how to tackle this problem?
Thanks a lot, Hugo
Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.
First I think a description of my overall project is needed:
Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).
My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.
Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.
Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.
This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.
So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.
And is a data structure really required for me to use a database?
I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks
I execute the stored procedure specifying acDataBuf as 0x21222324252627 which translates to "ABCDEFG" ascii codes.
The resulting field display is !"#$%&' which is hex: 0x01020304050607 (the "2"s got dropped)
When I modify the code by adding a line sval="hello" the resulting field display is "hello" This tells me as long as sval is assigned a proper string, the rest will work ok.
So something must be wong with the line String str = .....
Code Snippet
[Microsoft.SqlServer.Server.SqlProcedure]
public static int vciWriteDataCS
(
String acPointType,
String acPointName,
String acVECName,
byte[] acDataBuf,

{
using (BinaryReader rdr = new BinaryReader(new MemoryStream(acDataBuf)))
{
String sval = Encoding.ASCII.GetString(rdr.ReadBytes(FieldDef.iLen), 0, FieldDef.iLen);
vciSqlCommand.Parameters.Add(new SqlParameter("@data_params", SqlDbType.NVarChar));
vciSqlCommand.Parameters["@data_params"].Value = sval;
Any words of wisdom?

First of all let me say that ASP.NET a new programming environment for me so please forgive my ignorance.
Can someone please tell me how to write data to a SQL table that is a Binary data type? I have a stored procedure on the SQL server that I am calling to insert data into a table. I build a parameter list and set the values. It worked just fine before I added a binary field to the SQL table. My problem is that I don't know how to set the Binay data type to pass it to the stored procedure. Here is part of the code:
GetCMD = Myconnection.CreateCommand
GetCMD.CommandType = CommandType.StoredProcedure
GetCMD.CommandText = "SCHEMANAME.InsertLineItem"
GetCMD.Parameters.Add("HEADER_ID", SqlDbType.VarChar, 150)
GetCMD.Parameters("HEADER_ID").Value = "some value"
GetCMD.Parameters.Add("@OPTIONS", SqlDbType.Binary)
GetCMD.Parameters("@OPTIONS").Value = HOW DO I SET THIS VALUE????
rowsaffected = GetCMD.ExecuteNonQuery()
I assume serialization but have not figured out how. Anyone's help is greatly appreciated!!
Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{
FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam
I need to select all the records in a table, loop through them one by one, calculating some new field data, and then write the new data back to the same table. Here is the basic structure of what I've come up with:<CODE>SqlCmd = SqlConn.CreateCommandSqlStatement = "SELECT ProductID, Name FROM tblProducts"SqlCmd.CommandText = SqlStatementSqlRdr = SqlCmd.ExecuteReaderIf SqlRdr.HasRows Then While SqlRdr.Read If SqlRdr.FieldCount > 0 Then ... SqlWriteCmd = SqlConn.CreateCommand SqlStatement = "UPDATE tblProducts SET Name = '" & NewName & "' WHERE ProductID = " & CStr(ProductID) SqlWriteCmd.CommandText = SqlStatement SqlWriteCmd.ExecuteNonQuery() SqlWriteCmd = Nothing End If End WhileEnd IfSqlRdr.Close()SqlCmd = Nothing </CODE>I get an error that tells me to close out the Reader before trying to execute the write query. But I can't close it out for the loop to work properly. So I assume that there must be another way to do this simple task, but I'm so new to all of this that I need some help! Thanks!
View 1 Replies View RelatedI am new to database programming. What I want to do is have a database on a clients PC to use as data storage. This program will connect to a program running on our server (via TCP) which will store this information in another database. The clients database will only be accessed by my program - so I think that I don't need to register it with SQLEXPRESS. The servers database will probably need to be so another program can access it.
The problem I was having was writing and reading to a database that I created inside Visual Studio 2005. As I see it, there could be three issues - reading, writing, or setup of the database. To find out this issue I downloaded the Northwind database. The code below returns column 0 row 0 of the Customers table.
Code Snippet
NORTHWNDDataSet northwindDataSet = new NORTHWNDDataSet();
NORTHWNDDataSetTableAdapters.CustomersTableAdapter customersTableAdapter = new NORTHWNDDataSetTableAdapters.CustomersTableAdapter();
customersTableAdapter.Fill(northwindDataSet.Customers);
string data = (string)northwindDataSet.Customers.Rows[0].ItemArray[0];
Console.WriteLine("COL 0 - ROW 0: " + data);
This code returns "ALFKI". Which is what is in col 0 row 0 (This can be checked by right clicking on the Customers table in NorthWNDdataset.xsd and selecting preview data).
Next is writing. This is where I have the issues. The method below is one way that I tryed.
Code Snippet
DataRow row = northwindDataSet.Customers.NewRow();
row[0] = "1";
row[1] = "2";
row[2] = "3";
row[3] = "4";
row[4] = "5";
row[5] = "6";
row[6] = "7";
row[7] = "8";
row[8] = "9";
row[9] = "10";
row[10] = "11";
northwindDataSet.Customers.Rows.Add(row);
try
{ customersTableAdapter.Update(northwindDataSet.Customers);//table);
northwindDataSet.AcceptChanges();
MessageBox.Show("Update worked");
}
catch
{
MessageBox.Show("Update do not work!");
}
The messagebox shows "Update worked" - yet the data did not get added.
Thanks in advance.

Halo, I am a bit new to this
Please can someone help me, I would like to write a file(Any type) to a SQL database like a attached document(s) for the current record and be able to detatch the document when needed.
I use VB.NET for a ASP.NET app.
I basicly would like to attach documents to a piece of equipment may it be any kind and if the user views the equipment he will be able to detatch the documents for that piece of equipment and open it with the correct software.
PLEASE HELP!!!!!!!
It looks like its not possible to both read and write the same variable from a script using the conventional Me.Variables.<variable> syntax.
I can only assign a variable as Readonly or ReadWrite and not both. If I assign it ReadOnly I can only access it in the PreExecute subroutine. If I assign it ReadWrite I can only access it in the PostExecute subroutine (in fact doesn't this just make it WriteOnly in fact?). So I can only either read in or read out a variable using this syntax, noth both. Is this right?
So the read and write a variable to a script, the VariableDispenser approach is the only option to use. Is this right? and is it documented somewhere that this is how to use variables in scripts. Thanks.
Hi,
I want to make an application that fills in the variables into a dtsx package (ssis).
I'm able to read the variables created in the package
Application app = new Application();
Package p = app.LoadPackage(pkg, null);
Connections myConns = p.Connections;
foreach( Variable v in p.Variables){
Console.WriteLine(v.Name);
Console.WriteLine(v.Value);
Console.WriteLine(v.Namespace);
Console.WriteLine("/////////////////////");
Console.WriteLine("/////////////////////");
}
i'm also able to add on
Variable myVar = p.Variables.Add("amyCustomVar", false, "User", "3")
When the applications is closed the package does not contain the variable. So this is all done in memory.
Is their a way to actually write the variable into the physical package.
I'm doing a test package which reads a flat file, makes an adjustment using the derived column task and writes to the same flat file. But, the read locks the flat file, so the write can't access it. Any ideas for a resolution?
Thanks,

We have a package that is using a ForEach loop container to access files on a network drive. For some reason I am getting a message that the ForEach enumerator is empty and did not find any files that matched the pattern. For the pattern I left the default *.* for testing purposes. I have specified the file folder as \remoteserverfilesharesubfolder and also as \remoteserverc$filesharesubfolder and have gotten the same message. However when I map a network drive and set the file folder to the network drive it finds the files. Is this a permissions issue?
After I finish processing the file I want to move it to a new directory. Once this is deployed in production, the package will not be running under a domain account and probably won't have access to the network folder. Is there any way to specifiy in the connection manager itself that it should use a specific account to access the folder?
TIA,
Sabrina
I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?

I am not running a sql to insert or update the table. This is through the EDI.

Any ideas?
When using AquaData or JDBC (inet tds driver), when doing an insert using SqlServer 2005, I get error "String or binary data would be truncated" when the data is actually OK. There are no triggers, etc. that would confuse the situation. It works fine in SqlServer 2000.
The scenario is as follows:
Create table:
create table test3 (
name varchar (18) ,
tbname varchar (18)
)
Create and populate table:
create table maxtable (
tablename varchar (18) not null,
[...]
)
Try to insert into test3:
insert into test3 (name, tbname)
select i.name, o.name
from dbo.sysindexes i, sysobjects o, maxtable m
where i.indid > 0 and i.indid < 255
and i.id = o.id and i.indid = 1
and o.name = lower(m.tablename)
And I get the error "String or binary data would be truncated." The values being selected for i.name and o.name have maximum length of 18. There are other rows in sysindexes and sysobjects with longer values, but they are not being selected.
The error does not occur with SQL Server Management Studio, and does not occur using SqlServer 2000.

View 1 Replies View RelatedI am getting the following error running a data flow that splits the input data into multiple streams and writes the results of each stream to the same destination table:
"This operation conflicts with another pending operation on this transaction. The operation failed."
The flow starts with a single source table with one row per student and multiple scores for that student. It does a few lookups and then splits the stream (using Multicast) in several layers, ultimately generating 25 destinations (one for each score to be recorded), all going to the same table (like a fact table). This all is running under a transaction at the package level, which is distributed to a separate machine.
Apparently, I cannot have all of these streams inserting data into the same table at one time. I don't understand why not. In an OLTP system, many transactions are inserting records into the same table at once. Why can't I do that within the same transaction?
I suppose I can use a UnionAll to join them back together before writing to a single destination, but that seems like an unnecessary waste and clutters the flow. Can anyone offer a different solution or a reason why this fails in the first place?
Thanks in advance.

I have a table which uses binary data to store passwords. How do I view the contents of the "binary data" column, ie. the passwords? It just shows it as <binary data>?
We have a dll that sends a hexadecimal data (const. length) to MS SQL Server database. It's declared as String in VB, the db column data type is binary.
Here is the SQL String that has been executed successfully in Query Analyzer:
"declare @MyHAX varchar(32)
select @MyHAX='0x3236374535454337363145313430463742394545 413443473230343544320000'
insert MyTABLE (MyCOLUMN)
values (convert (binary(32),@MyHAX))"
When I am trying to do the same thing in the insert stored procedure, I get an error message: "Disallowed implicit conversion from data type varchar to data type binary, table 'MyDB.dbo.MyTABLE', column 'MyCOLUMN'. Use the convert function to run this query."
Does anyone know how can I insert my binary data?

I am trying to store a byte array in a database. I want to use binary to store the data but I am confused about the type. The byte array I am trying to store is a password hash from SHA512.
I hash a plain text value then store the result in a byte array. I then want to store the byte array in the database as binary but I am confused when its asking for the size of the binary field. In nvarchar a size of 2 would mean 2 characters.
How should I choose the size of this binary field, and what does the size mean. If I choose a size of 6 does that mean 6 characters, like 010110. Or is it stored differently?
The maximum size of a plain text password is 30 characters, and the salt used to generate the SHA512 hash has a maximum size of 16, but I don't know the exact size of the salt because its randomly picked when the salt is generated.
I need to make sure the size of my binary field will hold the largest possible password hash, but I don't want it too large so its never completely used.
How is this data stored in the binary field, and what size binary field should I choose to make sure there are no problems with the password hash being truncated, yet making sure I'm not just wasting by creating a field thats too large.
Thanks!
Hello,
I need to generate HASH of text values for my app. I can generate hash values for normal fields using CHEKCSUM and BINARY_CHECKSUM function but it does not support checksum of text, ntext, image, and cursor, as well as sql_variant.
How can I generate checksums of such datatype.

I posted this in the Windows Forms Data Binding section, and they directed me to the .Net data section. I posted it there and waited a week with no replies. I'm hoping someone here can at least give me an idea of what the problem might be.

I am trying to use a recordable CD as the storage medium for a comma delimited flat file destination in an SSIS package. I am running the developer edition of SQL Server 2005 on Windows XP SP2.
I discovered that in the file connection manager for a flat file, the path to the file can point to a directory on the CD-R. When I set the file name for the connection manager and point it to a file on the CD, the path looks something like this;
C:Documents and SettingsjuserLocal SettingsApplication DataMicrosoftCD BurningArchiveMonthlyMCTxnDetail_Archive.txt
When I run the package, the packge executes without a problem, but no 'burning' occurs. When I check the directory specified in 'file name', there is a header in the directory that states, 'Files Ready to Be Written to the CD'. The file I want to write to is listed there.
Is there some executable I can kick off in another task to complete the process of burning the file to the CD?
Thank you for your help!

Hi Folks,
After I inserted a row in my Database (row 27) I started getting this error when I try to insert, update or delete the record in the database.
I've searched about the error on google and it says that I should have a field that crossed the limit of characters.
I have only the autoincrement field, two varchar fields and a text field, neither one of the varchar fields crossed the limit, they arent even close. I found in google that one solution would be turn the field that is having problems in a text field, but the only field that actually can be causing the problem already is of the text type.
The exact error I get on VS 2005 when trying to change something in the row 27 is:
"No row was updated.
The data in row 27 was not committed.Error Source: .Net SqlClient Data Provider.Error Message: String or binary data would be truncated.The statement has been terminated.
Corret the errors and retry or press ESC to cancel the change(s)."
I need some help guyz, see ya, hugs.
