Uploading binary file by using Inputsteam [modified]

3-Jul-06 2:26

Using the DataAdapter and TableAdapers, you can't. They require keys on the tables you use them with.

Either you'll have to add keys to your tables, which is highly recommended, or you'll have to write your own procedures for udating records using fields that can uniquely identify each record.

Hi! All

I have a problem when I tried to upload file by using system.IO Inputsteam my code is following

Dim UploadedFile As HttpPostedFile = FileUpload1.PostedFile

Dim binFileData As Byte()
ReDim binFileData(UploadedFile.ContentLength)
UploadedFile.InputStream.Read(binFileData, 0, UploadedFile.ContentLength)

Dim strConn As String = "Server=[servername];Database=[dbname];UID=sa;PWD=sa;"
Dim connection As SqlConnection = New SqlConnection(strConn)

Dim str1 As String = "Update DocumentImage set DocImage = @CVData where DocumentID=122"
Dim command As SqlCommand = New SqlCommand(str1, connection)
Dim param1 As SqlParameter = New SqlParameter("@CVData", SqlDbType.Image)
param1.Value = binData
command.Parameters.Add(param1)
connection.Open()
Dim numRowsAffected As Integer = command.ExecuteNonQuery()
connection.Close()

It said Cannot access a closed file. on codeline

UploadedFile.InputStream.Read(binFileData, 0, UploadedFile.ContentLength)

The contentLength was 292836 and the ContentType was "application/pdf"
and I have already put the config into web.config

<httpruntime
="" executiontimeout="1200" maxrequestlength="1000000" usefullyqualifiedredirecturl="false" minfreethreads="8" minlocalrequestfreethreads="4" apprequestqueuelimit="100">

But it didn't work fine
Is there somebody who know how to solve the problem this?

thank you in advance

Oracle 9.2 Stored Procedure help in VB .NET

I'm receiving an error when attempting to use an Oracle stored procedure in a VB .NET 2005 application; the database is Oracle 9.2. The error is ORA-06550 wrong number or types of arguments in call to <sproc name="">. I'm making the call with an Oracle DataReader. The sproc is pretty simple - selecting two columns from a database table, it doesn't even have a WHERE clause.

I've Googled the error and seen that other people have come across the error but I haven't seen any solutions to the problem.

Any help / suggestions would be appreciated.

A snippet of code would be helpful too. Please show the code where you build the command object (Probably OracleCommand) and add the parameters to it. And also show the the signature of the stored procedure (the SQL code that defines the name and parameters of the stored proc)

Handling Errors
As with the Statement and PreparedStatement objects we have already covered,
if there is something wrong with your stored procedure, callable-statement
syntax, the call to your Connection object's prepareStatement() method will
throw a SQLException. The most common SQLException occurs when a
procedure or function does not exist:
SQL Error: ORA-06550: line 1, column 13:
PLS-00201: identifier 'TONUMBERFUN' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
This error may come about because the procedure or function does not actually exist in
the database, or it could be that the username you are using when you call the stored
procedure does not have EXECUTE rights on the procedure.
After you create a CallableStatement object, you need to register any OUT
parameters before executing the statement. Next, let's see how you do that.

dear friend...
if i have a form in vb.net such as (A) and another application in c language such as (B) how can i control the application (B) from the buttons based on form (A) and i mean of control :
1-run application B
2-minimize and mazimize form B
3-close form B
4- the most thing is make the form A always active that mean you cant use the appliation B except throught the form (A)

thanx all

SQL Script to delete empty rows in a table

3-Jul-06 2:20

First, you can NOT make another application a modal child of your own. Once launched, there is nothing you can do to reliably stop a user from switching over to the other application and using it without your interface.

It's very easy to launch the other app (point 1 in your post).

Point 2 is also pretty easy. All you need to do is get the Window handle of the launched app and call the Win32 function ShowWindow with the appropriate parameters.

Point 3 is a bit more complicated, despite it's seeming ease. You can easily tell the application to exit, but if it wants to show some window that wants comfirmation of exit or saving changes, then you've got a problem. You have to find those windows, if they exist, then send the appropriate commands to those windows.

Point 4 - Not practically possible. There is nothing you can do to prevent the user from skipping your app, or shutting it down, and just using the app your trying to control.

Point 5 (you didn't put this) - How do you intend to control the other application?? The only way to do it is not reliable and is far more complex than the benefits your going to get from implementing it.

Hello,
How do you delete a row in vb.net where there is blank data?

I've tried the following, and all do not work...

strSQL = DELETE FROM tblProducts WHERE prodID = & " "

strSQL = DELETE FROM tblProducts WHERE prodID = & Nothing

Thanks in advance.

Aren't your quotes in the wrong place?

Rashar wrote:

What do you mean by "blank data"? From the two examples you gave you appear to be trying to check whether prodID is an empty string (or is that a string with one space), or possibly if it is NULL.

strSQL = "DELETE FROM tblProducts WHERE prodID IS NULL"

strSQL = "DELETE FROM tblProducts WHERE prodID = ''"

The first checks for a null (i.e. the absense of any value), the second checks to see if the value is an empty string.

One of these is likely what you want - but you'll have to be more definite about what consitutes "blank data" in your vocabulary.

Yes. I'm looking to delete the record where prodID is a null field.

I will try the first option.

Thanks

Dave Kreskowiak3-Jul-06 2:06

ProgID sounds like it should be a Primary key. If that's the case, why would it ever be NULL?? If this is the case, you've got much bigger issues that just finding and delete "empty" records. In a properly designed database, this procedure your trying to put together should never be necessary.

Actually, I was just using it as an example for a column name. I do have it set to a primary key, it's just that my end user may save a blank form which would populate the prodID column, but the rest of the columns may all be blank. If so, I wanted to clean up the table if there are columns that are blank. I could make it so that all the columns are not null, but with my program it can't work that way, as I need to request an ID first and foremost.

Thanks.

That's what validation is for! Validate the fields before you allow the user to save the record. If all the fields are not filled in, there's no reason you should be letting the user save an incomplete record.
