My Repeter control in not displaying the images from databse when i use the following statement.
<asp:image id="Image1" imageurl="<%" container.dataitem%=""> Runat=server>
actuall i want to display all the images from data base along with the price of image.
what should i do?
i'm not getting a point when i give any image path instead of
ImageURL= <% Container.DataItem%> replace ImageURL= "pic.gif"
then it shows no of times this image that i have no record in my database
suggest me.
thanx

Use the "Ignore HTML" option when you post the message so that your code will be visible.
---
b { font-weight: normal; }

actually what i want to do i have a table category
in this a user can upload the images for the category.
now i want to display the all the category information with the image on the home page of the site in a 4 * 4 matrix.
what should i do?
thanx

Read my previous post again. Repeat until it sinks in. There is noone that can help you with your code if they can't see it.

Hi Guys!! I have minimised a window into the Sys Tray. When i hover over it, a Balloon Tip Pops up. But when i Right Click on it, the Context Menu shows up but the Balloon Tip doesnt go away. How do i get to remove the Balloon Tip once i click the Right mouse Button on it?
The Code for getting the Balloon Tip is:

Hi Guys!! I have a window in my Project which i minimize, which then goes in the System Tray. But when i restore the Window, the State of the Window is always the same. I want to know what i can do to save the WindowState before minimising, so that when i restore the window, it must restore in the earlier state.
For Eg. If the Window is Maximised first, and then i send it to the System Tray. Later when i restore the Window, it must be in Maximised State only. If the Window was not in Maximised state, then later when i restore the window, it must not be in the Maximised State.
If anybody understood what i just tried to explain, could someone tell me how it can be done. Thanx!! Bye!!

Unfortunately, Forms don't have a Minimized event.
You'll need to catch the Form's SizeChanged event instead. This event will be raised on Minimize, Maximize, Restore, window size change, and on form load. You can detect whether or not the form is being minimized by checking the Form.WindowState property.
Private Sub myForm_SizeChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)_
Handles MyBase.SizeChanged
If (Me.WindowState = FormWindowState.Minimized) Then
' Form has been minimized. Store settings here.
End If
End Sub
Recognize that this event will be raised when the user stretches the form too, so you'll need to handle that case.

Hi Guys!! I'm Devraj and i have almost completed my Project (DevNik: A Bit Torrent Client) in VB.NET 2005
I'm in need of a Vb.NET ActiveX Control which i could use to display the Download and Upload Rate in my Client. Has anybody heard or know about such a control which will be helpful to me. I need something like the TaskManager in WinXP, just that it must have 2 lines, one for Download rate and the other for Upload rate.
If anybody knows of such a control  , plz could you send me a link or give me some idea where i might get it. I'm also welcome to any alternatives or suggestions. Thanx in Advance ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) . Reply Back to me.

Visual Studio comes with a free MSChart.ocx (ActiveX). However, I recommend that you steer clear of ActiveX controls in .NET. COM interop is slow and COM/ActiveX objects are very prone to DLL hell.
Instead, I recommend that you use a .NET graph control. Such as the ZedGraph[^] control which is free and way better than MSChart.

Hi All,
I am using datagridview control to display data in the datagrit. Datagridview is bound to a data source, nothing very complex. I want to insert data as I tab out of a new row( and data entered into that new row) and come to the next row. It should do it automatically.
Can any one please give me any ideas at to how I could do that?
Thanks a lot!!

Hi Everyone,
In VB.NET application, I want to copy a structure into a 2 dimensional array using CopyMemory.
just for your idea giving you the structure defination.
'for storing the pixel arrays...
_
Private Structure SAFEARRAYBOUND
Dim cElements As Integer
Dim lLbound As Integer
End Structure
_
Private Structure SAFEARRAY2D
Dim cDims As Short
Dim fFeatures As Short
Dim cbElements As Integer
Dim cLocks As Integer
Dim pvData As Integer
Dim Bounds() As SAFEARRAYBOUND
End Structure
I have gone through many forums but couldnt able to find the appropriate answer.
Expecting a solution soon.
Thanks

Hey thanks for you response. But I have tried that way too. but couldnt get success. Is there any other alternative......????

By default, the compiler will "optimize" your structure by re-ordering its fields. Because of this, you'll need to define that your structure's fields be layed out sequentially in memory. You can do this via the StructLayout attribute as follows.
<System.Runtime.InteropServices.StructLayout(Runtime.InteropServices.LayoutKind.Sequential)> _
Public Structure SAFEARRAYBOUND
Dim cElements As Integer
Dim lLbound As Integer
End Structure
I've found an article on this website explaining how to do a CopyMemory call in VB.NET. It also goes over .NET marshalling too. Perhaps this will help you?

that too i have done and also gone through the article.....but major problem is that i could not be able to convert this sequential structure into 2 dimensional array.......basically i need to covert this structure into 2 dimensional array which gives pixel information......and later on i will convert it into one dimensional long array.....thats wht my purpose....

How is your 2 dimensional array defined?
How will it be used?
|

Public Function LongPixels() As Long()
'_____________________________________________________
'
' Purpose: converts the 2-dimensional 3/4 Byte DIB into a one-
' dimensional Long array, for easy summing of long int values.
' scans from left to right, then bottom to top.
' diblongarray(0) = lower left pixel.
' diblongarray(ubound) = upper right pixel.
' Assumptions: the DIB is 24-bit, the byte order of the pixels is
' r-g-b (not the common b-g-r)
' Affects:
' Inputs:
' Returns:
'_____________________________________________________
Dim bDibMag() As Byte '2 dimensional byte array holds pixels by row,col
Dim lX As Long, lY As Long 'x = pixel col, y = pixel row
Dim saDibMag As SAFEARRAY2D
Dim lXEnd As Long
Dim l As Long
Dim lCol As Long
On Error GoTo Cleanup
'structure the 2-dimensional safearray
With saDibMag
.cbElements = 1 'bytes to an element
.cDims = 2 'dimensions
.Bounds(0).lLbound = 0 'lbound of 1st dim
.Bounds(0).cElements = Height '# rows = height in pixels
.Bounds(1).lLbound = 0 'lbound of 2nd dim
.Bounds(1).cElements = LineByteWidth() 'calculate width with 24/32 row pad
.pvData = lPtrDibMag 'pointer to the DIBits
End With
'HH: MoveMemory is not available in Windows API but in Win32 API, similar command in current API is CopyMemory
'for MoveMemory, it's definition: Sub MoveMemory(pDest As Any, pSource As Any, ByteLen As Long)
'it moves a block of memory from one location to another.
'VarPtr: retrieves the memory handle of an object.
'ATTN: while calling using ByVal, it transfer the the source's memory handle
'if calling byRef(default), it instead transfer the tempoary variable that stores the souce's memory handle
'in a simple way, the following command is a quicker way, if there's a bunch of data, to pass values
'of source variable to destination variable
MoveMemory ByVal VarPtrArray(bDibMag()), VarPtr(saDibMag), 4 'copy safe array to bDibMag
lXEnd = (Width - 1) * 3
l = 0
ReDim lColor(Width * Height - 1) '4 MB
'HH: FOLLWING LOOP READS TWO DIMENSIONAL VALUE AND STORE THEM INTO A ONE-DIMENSION LONG ARRAY
'HH: READS VALUE FROM BOTTOM TO TOP
For lY = 0 To biDibMag.bmiHeader.biHeight - 1
DoEvents
'HH: FOR EACH ROW, READS VALUE FROM LEFT TO RIGHT
For lX = 0 To lXEnd Step 3
MoveMemory lCol, bDibMag(lX, lY), 3
lColor(l) = lCol
lCol = 0
MoveMemory ByVal VarPtr(lCol), 0&, 3
l = l + 1
Next lX
Next lY
LongPixels = lColor
lPix = l 'store pixelcount
'zero out the moved memory, so as to avoid
'a pacman-like memory-use situation
MoveMemory ByVal VarPtrArray(bDibMag), 0&, 4
Cleanup:
Erase saDibMag.Bounds
Erase lColor
Erase bDibMag
If err.Number <> 0 Then WriteLog "MAGRAS ERROR In Procedure LongPixels, #" _
& err.Number & ": " & err.Description
err.Clear
End Function
this is the VB function which i need to convert to VB.NET...this is the way i have defined the two dimensional array in VB.NET project..
Dim bDibMag(,) As Long '2 dimensional byte array holds pixels by row,col
Thanks again for taking interest in this problem..

After looking at your code, the only reason MoveMemory() is called is for performance reasons. Maybe in VB6 this was faster, but in VB.NET I doubt it. The reason is because a call to MoveMemory() is a call to unmanaged code, requiring a P/Invoke, which is a performance hit in .NET. I suggest that you make it easy on yourself, remove all of the MoveMemory() calls, and just iterate through the 2d array and directly copy the color values into your 1d array. You can look into boosting performance after you get it working.
Also, there appears to be a lot of legacy VB6 calls in your VB.NET code. You may just want to rewrite the whole thing.
You should replace your "On Error Goto" with Try/Catch.
You should replace "DoEvents" with "Application.DoEvents()".
Do a "Return lColors" instead of "LongPixels = lColors", and perhaps return an empty array on error.
