Hi All,
Is it possible to move image files around an ImageList during run time after the ImageList has been populated at design time?
Basically i'm looking for the code syntax for being able to sort image files (*.gif) in an ImageList.
Can this be done using the "index" value of the stored images?
thanks

There isn't any way to sort an existing ImageList. You can Add images to the end of the ImageList and RemoveAt any index in the list, but you can't "AddAt", "Insert", "Move", or "Swap".
I can see a possible way to do it, but you'd end up extending the existing ImageList class and supplying the code to InsertAt or Swap. The only way I can see supporting this is making an entirely new ImageList, copying the images from the source ImageList one at a time to a new ImageList and stopping at the appropriate places to make whatever changes are needed.

Thanks for putting me out of my misery Dave. I also had the idea of generating another imagelist but was trying to do things more compactly if possible.
Do you know if there is a way of extracting the index of the image file as an integer and store it as another variable?
thanks

Are you syaing that you want the .Add() method to return the index that the image was put into? .Add() is a sub and doesn't return a value. Since the new image is always appended to the end of the collection, you can probably use the Items.Count property to find out what the next index is going to be before you .Add() the image.

Hello to all of you.
If anyone knows I would ge glad if someone could help me on this:
I have a form where there is a panel (call it panel_1). In this panel I want to display 5-6 panels, one at a time, depending on some buttons. Here is what I do. In visual studio .net, I create a new userControl class where I place my panel (panel_2). Then, i go to my main form, where panel_1 is and I add my userControl. But the buttons of panel_2 are BLACK, and it seems that there is no refreshing.
When I run the application, the part of the screen that has panel_2 shows abnormal things such as icons of my desktop!
Is there any bug, when adding userControls. Do i need to do anything, such as repaint or something else?
Thank you in advance!

Hi All,
Am getting a problem in crystal reports when getting connected through the dataset.Iam not knowing where the code goes wrong.
In button_click,am generating the dataset and finally
Dim oRpt As New rptDemo
oRpt.Load()
oRpt.SetDataSource(myDs)
crystalreportviewer1.ReportSource = oRpt
Am getting a blank report. Can anyone help me?
Thanks in advance,
|
|
|
|
|
you need to supply the path to your template file to the oRpt.Load call.
oRpt.Load("c:\myReportTemplate.rpt")If you haven't yet defined a report template, then you should do that first when attempting to utilize crystal in this manner.

Hi Jim,
Thanks for ur response. Even then am not getting it.
Problem is Iam getting the report, its header fields and all that... but am not getting the values for them. what might be problem.
what might be the problem..?
Basically i have a form with two(let's say) fields and a submit button.On button click, I want to check the access database with these two fields and want to generate a dataset.
Finally, i want to use this dataset to generate a report
Just to test whether my dataset has values or not i just binded it to the datagrid.Its working fine.
Why am not getting the values when am passing it to the report...?If u have any samples regarding to perform the same Would you let me know..?
Thanks in advance

well, if you have data in the datagrid and you're using the above code to populate the report, i would have to guess that something is wrong in your report template.
check to make sure that in your report template, when you select a datasource you select ADO.Net and point to a schema file that represents the structure of your dataset. then, make sure that you set the relationships of the tables properly on the links tab.
what i actually like to do here is write my code for populating the dataset first, then step through the debugger and write the dataset out to an xml file including the schema.
then use this file as the source for your report. this way you ensure that the xml you're passing to the report template in your code is the same as what you are designing the report with.
hope this helps.

How j can find the dominant color in a bitmap with a function or with the ColorMatrix?
|
|
|
|

This should get you started, it has routines to count and average colors:

hello
i just want to know whay the boolean type take two bytes in the memory knowing that a simple one bit is enough ???
|
|
|
|
|
It actually only takes one byte. One byte is the smallest possible allocation unit in the Intel x86 architecture. The compiler maps your boolean value into that byte.

I created a DLL in VC++ 6.0. I am using it in VB 6.0. I
need to debug the DLL when I call a function in the DLL.
How do I do it from VB6?

You are trying to do this backwards. What you do is create the VB6 application that calls the C++ DLL and then debug the DLL in the C++ debugger.

plz help me if any body have solution of this problem .
I have a big problem with .NET.
Short Description:
As long as I have an empty From in my Windows Application everything
works fine, but as soon as I add any kind of Control (e.g. a Button) to
the Form I get the following Exception in the InitializeComponents
method
*
An unhandled exception of type 'System.ArithmeticException' occurred in
system.drawing.dll
Additional information: Overflow or underflow in the arithmetic
operation.*
I read on a discussion board that this is caused by something called FPU
Exceptions which could be enabled by a hardware part of my machine.
Is there a Way to find out which part? Or is there a Way to turn them
off except the one on the MS Site?
Please help me if any body have solution of this problem

It would appear that your connection string isn't valid. Specifically, my first suspect would be the path you provided for Data Source. But, your question really belongs in the Embedded/Mobile forum.

I’m trying to write a function that returns a datatable. Within the function I’m calling a stored procedure in access. The code looks like this:
Public Shared Function LoadSearchResults(ByVal whereClause As String) As DataTable
Dim SQL As String = " EXECUTE qrySearchResult"
Dim dt As DataTable = New DataTable()
Dim da As OleDbDataAdapter = New OleDbDataAdapter()
dbConnection.Open()
'Dim Cmd As New OleDbCommand(SQL, dbConnection)
Dim Cmd As New OleDbCommand()
Cmd.CommandType = CommandType.StoredProcedure
Cmd.CommandText = "EXECUTE qrySearchResult"
Cmd.Parameters.Add(Cmd.CreateParameter())
Cmd.Parameters(0).Value = whereClause
'''''dr = Cmd.ExecuteReader()
''''''''''''''''''''
da.SelectCommand = Cmd
da.Fill(dt)
dbConnection.Close()
dbConnection.Close()
Return dt
End Function
How can I accomplish this?
Thanks,
Martin

Whatr's the problem ?
Why are you closing your connection twice ?

The problem here is that I don't know how to get a datatable from: dr = Cmd.ExecuteReader().
Please ignore the 2nd dbConnection.Close().
