Someone to help me with a vb6 code that can save Picture into an access/SQL Server database.
Presently i save the Picture Path as a string inside the database table but i want the actual picture to be saved as part of the table.
What is the implication of saving picture inside access table?

Not Sure on the implication or the how to do the above task... what are you trying to use this picture int he database for? I might have a few Ideas on how to accomplish the same thing without the hastle of figuring this out.

thanks

Search for BLOB's at www.msdn.microsoft.com. I'd do it for you but I'm here on my mobile  I've had the same question before and that's the answer I got.

i dont know how to do it in vb but in vb.net if u want to store picture in Sql or access , u first have to convert ur picture in binary format , then store it in sql / access in [image] field. and to vice-versa to show in ur form.This is all u have to do to store pics in database.
I think it works for u .

you can use an application .config file to specify the location of the database then refer to the application .cofig file when pointing to the database with your connection string. To get to the app.config file ... right click, add new item, app.config... then open it you should see something like mine below. The easiest way to get a good connection string for <add key...="" is="" to="" use="" your="" data="" adapter="" and="" just="" copy="" the="" conn="" string="" in="" field="" connection="" string.
hope="" this="" helps="" .
ex.
<?xml="" version="1.0" encoding="utf-8" ?="">
<configuration>
<appsettings>
<add key="odaCustomer.ConnectionString" value="Jet OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Registry Path=;Jet OLEDB:Database Locking Mode=1;Jet OLEDB:Database Password=;Data Source="\\Sfssv01\userapps\SFS OTR Rate Prg\dbsharp.mdb";Password=;Jet OLEDB:Engine Type=5;Jet OLEDB:Global Bulk Transactions=1;Provider="Microsoft.Jet.OLEDB.4.0";Jet OLEDB:System database=;Jet OLEDB:SFP=False;Extended Properties=;Mode=Share Deny None;Jet OLEDB:New Database Password=;Jet OLEDB:Create System Database=False;Jet OLEDB:Don't Copy Locale on Compact=False;Jet OLEDB:Compact Without Replica Repair=False;User ID=Admin;Jet OLEDB:Encrypt Database=False">
<add key="mskPhone.Visible" value="True">
Ex. Conn String (Access) "if need another database tell me..."
'Place This in a Module
Public cnnRate As New OleDb.OleDbConnection
Public odaCustomer As New OleDb.OleDbDataAdapter
Public Sub Connect()
Try
cnnRate.ConnectionString = _
System.Configuration.ConfigurationSettings.AppSettings("odaCustomer.ConnectionString")
Catch ex As Exception
MsgBox(ex)
End Try

Also ... if you have plans for deployment and other issue's let me konw so i can tell you about other small details that might get in your way. The idea above allows for configuring the connection string at any point after installation... you can simply open the app config file after install with notepad and change the small section refering to connection string. Then its fixed

We just upgraded from VS2003 to VS2005 and we've been having some conversion errors.
For this line of code:
origDV.RowFilter = String.Format("Weight < {0} OR Diameter <{1}", Leg.LookupTotalWeight(), Leg.LegWidth) ' + CStr(Leg.LookupTotalWeight()) + " OR Diameter <" + CStr(Leg.LegWidth)
We are getting the error 'Cannot convert System.Decimal to System.SqlTypes.Double'
Any ideas on how to correct this? We're not finding a lot of information.

Converting from decimal to double is a narrowing conversion with potential for losing precision but not information about the converted value. It's bad casting but it won't throw you an exception. Try declaring your decimal value as double instead.

I was wondering the best way to go about importing the read only property to the mask edit boxes from VB6. I would like to know the same about a Combo Box as well... If I could get teh basic Idea for adding the Read Only Property to a control I could figure the rest out on my own.

Hi Guys,
Stupid question! 
I got a collection class, Customers, that should store classes of type Customer. Simple enough task. BUT!!! for some reason after I add my first customer class to the collection class every time I instantiate a new customer class the customer that is already in the collection gets the same data as the new customer. So in the end I get a ton of classes in the collection identical to the last class added.
The customer class has a private structure to hold customer info and the add method of the collection class passes the new customer class directly into the collection.
The new method of the Customer class gets the params byval and fills the structure so i don't how the previous instances of the class already in the collection assume that they need to change.
The whole thing is done vb2005.
Any kind of light shed on the issue would be greatly appreciated

Hard to answer without some code. Do you have some Shared fields within that customer class?
|
|
|

Hi Robert
Nope nothin is shared. All vars are private and if anything is passed to the Customer class it's byval.
Here is the Customer class:
<br />
Public Class clsSalesRecord<br />
Private Record As Object<br />
<br />
Public Sub New(ByVal SalesRecordObject As Object)<br />
Record = SalesRecordObject<br />
End Sub<br />
<br />
Public ReadOnly Property Reference() As String<br />
Get<br />
Return Record.id<br />
End Get<br />
End Property<br />
End Class<br />
Here is the collection class:
<br />
Public Class clsSalesRecords<br />
<br />
private _Records As Generic.List(Of clsSalesRecord)<br />
<br />
Public Sub Refresh(byval Record as object)<br />
_Records.Add(New clsSalesRecord(Record))<br />
End Sub<br />
HELP!!!

Are you always passing the same Record object into the Refresh sub? If yes then surely all your customers will point to the same reference...
|
|
|
|
|
 I appreciate the vote of confidence!
No!!!
Thats the thing, when the first class is added to the colection it has it's set of values. Then when i instantiate a fresh Customer class with a new record object and even before the new customer class is added to the collection the class already in the collection changes it's values to those of the fresh Customer. (My bad! I don't think I made this clear before  )
So it seems as if the collection is holding onto a ref of the customer class. This in turn is strange as you can see that Customer classes are passed byval into the collection.
Class params passed byval should preserve the structure of the reference class but not be references themselves....No?
Thanks for givin me hope

I was wondering what DB are you using? I might be able to give you an alternate way of looking at this if I knew...

Hi Michael
I'm using Access but I don't store this type of info in it anyway. Basically my app is an add-on extending an accounting software with its own proprietary db.
My app is using a separate db to store some info and i don't need to keep the customers etc. on my side.
Hence these classes are written as wrappers for a very !!!UGLY!!! sdk class library supplied with the software.
And at this point it's a matter of principle  for me to understand why this issue arises with collections of classes in .net.
If anyone could throw my way some code with a class collection I would greatly appreciate it.
I just want to know what  I’m doing wrong.
Thanks in advance

Ok Im Looking Through and trying to find where you call your refresh...
It seems to me that its passing the New Customer in Correctly... but the Refresh refreshes all of the info in the list to the newly saved customer... Tell me what you think while I try and write this ...
I use Stored procs for all of my database access so this is new to me as well.. so go easy on me but, i will give this an attempt and if anything everyone else will eb able to correct me and give you more insight.
Michael
