Hi all,
I am trying to code for storing images into database as bytes and for its retrieval. It worked well. But if we try to load more than two pictures one by one then it shows an error as follows.
---------------------------
Visual Studio Just-In-Time Debugger
---------------------------
An unhandled win32 exception occurred in VB6.EXE [1160]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time.
Check the documentation index for 'Just-in-time debugging, errors' for more information.
---------------------------
OK
---------------------------
I used GlobalAlloc function to allocate bytes of memory in my heap. I allocates almost 26347868 bytes in memory. I tried to free memory by using GlobalFree. But the result is same.
I will be thankful to you for your help.

Post your declaration of GlobalAlloc and GlobalFree - it looks like you may be passing the wrong parameter type...?

So what does this mean? Let's see the code that is storing and retrieving the images. How big are these images, in bytes?

Hi all,
Sorry to be late.

I meant, I can open any picture i stored in sql database in a picturebox. I stored picture as bytes. Opening of first and second picture (randomly from database) work smoothly. But when i try to open third image then it will show that error. I used following function to retrieve image from collection of bytes.
Public Function PictureFromBits(abPic() As Byte) As IPicture
' abPic() as a byte array
Dim nLow As Long
Dim cbMem As Long
Dim hMem As Long
Dim lpMem As Long
Dim IID_IPicture As GUID
Dim istm As stdole.IUnknown
Dim ipic As IPicture
On Error GoTo Out
GlobalFree (hMem)
nLow = LBound(abPic)
On Error GoTo 0
cbMem = (UBound(abPic) - nLow) + 1
hMem = GlobalAlloc(GMEM_MOVEABLE, cbMem)
If hMem Then
lpMem = GlobalLock(hMem)
If lpMem Then
MoveMemory ByVal lpMem, abPic(nLow), cbMem
Call GlobalUnlock(hMem)
If (CreateStreamOnHGlobal(hMem, CTrue, istm) = S_OK) Then
If (CLSIDFromString(StrPtr(sIID_IPicture), IID_IPicture) = S_OK) Then
Call OleLoadPicture(ByVal ObjPtr(istm), cbMem, CFalse, IID_IPicture, PictureFromBits)
End If
End If
End If
End If
GlobalFree (hMem)
Exit Function
Out:
MsgBox "Out"
End Function
I think this is a problem regarding memory. Please help.

To do a backup you need to issue the following command to your SQL Server:-
"BACKUP DATABASE myDbName TO DISK = 'd:\Backup\myBackupFile'"
for example :-
Dim connection As New System.Data.SqlClient.SqlConnection<br />
Dim command As New System.Data.SqlClient.SqlCommand<br />
<br />
With connection<br />
.ConnectionString = myConnectionString<br />
.Open()<br />
With command<br />
.Connection = connection<br />
.CommandType = CommandType.Text<br />
.CommandText = "BACKUP DATABASE myDbName TO DISK 'd:\Backup\myBackupFile'"<br />
.ExecuteNonQuery()<br />
End With<br />
.Close()<br />
End With
To do a restore is as above, except the SQL command to issue is :-
sSql = "RESTORE DATABASE myDbName FROM DISK = 'd:\Backup\myBackupFile'"
Be aware the path to the backup file is local to your SQL Server, not your workstation.

Try issuing the following command to SQL Server
USE Master <br />
<br />
ALTER DATABASE yourdatabasename SET MULTI_USER WITH ROLLBACK IMMEDIATE;<br />

What is the container that's going to be displaying this message? Is this a report? A web page? A RichTextBox? ?? Whatever that container is is going to dictate how you format and store your data that requires this formatting.

Crystal Reports supports RichText fields, but NOT all of the RichText formatting commands. This question would be better asked in the forums on BusinessObjects own website.

I thought the whole point was to generate a report? What else are you going to use to replace Crystal Reports?

I don't have any code or links because I've never had to support superscript and subscript in any reports.
You're going to have to do your own research for a reporting package that supports this kind of formatting in either RichText or HTML. You have a title of "Software Engineer". Stop begging and start engineering.

Hi,
I have a webpage with a check boxes. The user must be able to select which fields he/she wants to include in a SELECT statement. So I am going to have 1 checkbox for each field. I want these checkboxes to be created dynamically for each field.
I was thinking of doing it like this, for example with the long description field:
LongDescription AS "Long Description"
The "LongDescription" will probably be the name of the checkbox. And the "Long Description" will be displayed next to the checkbox as a description to the user.
How do I return columns only and not the rows of the records, how would I do this? I am using VB.NET 1.1.
Regards

Hi,
You really mean column names?. If you are using recordset then you can take field anmes by adors.fields(index).name.

I'm using VB.NET 1.1 and not using recordset.

Hi,
I have a data reader populated with rows from my SQL SELECT statement.
I am looping through the coloums to write it to a XML file. But I need the name of the column for the name of the element. This is how I am looping through it and writitng it. It's only a section of my code:
With writer
' Loop through the fields
For i = 0 To dr.FieldCount
.WriteElementString("[ column name ]", dr.Item(i))
Next
End With
Please can someone help?
Regards
ma se

I hust changed the start of the loop to:
For i = 0 To dr.FieldCount - 1
|
|
|

Why are you writing this out to an XML file yourself? The DataSet and DataTable classes already do this for you, using their WriteXml methods.
