Dave,
Since posting this question, I have resolved how to display an Image in a DataGridViewTextBoxColumn.
Dim imageCell As New DataGridViewImageCell<br />
Me.DataGridView1.Item(2, 0) = imageCell<br />
Dim imageMe As New Bitmap("C:\Pictures\Graham.jpg", True)<br />
imageCell.ImageLayout = DataGridViewImageCellLayout.Stretch<br />
imageCell.Value = imageMe
That places the Image in Col 2, Row 0 and the other Rows in that Column, all accept Text input.
My problem now is to be able to do this to multiple Cells. In otherwords, reuse the variables, imageCell and imageMe as I won't know how many of these images there are until Runtime.
Any ideas on that issue please?
Regards, Graham

I needed to replace the disk on my development machine. Everything went fine. I had my VB.Net application backed up to DVD.
I reloaded the folder, and tried a build, I received 42 of these warning messages:
Namespace or type specified in the project-level Imports 'PegasusImaging.WinForms.TwainPro4' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
They relate to different Pegasus Namespaces (TwainPro, PrintPro, etc). I tried removing the reference, and adding it back in, but the warnings persist.

The only thing that would do this is your project is missing a reference or the libraries you're using haven't been reinstalled and properly registered.

I am working on a attendance program (for a club) that pulls the dates (all of them) for a member from a database. I know how to display all of the dates but I was wondering if it is possible to group by week? For example, you have 3 dates (i.e. 05/07/2008, 05/08,2008, 05/09/2008) from last week and two dates from the current week (i.e. 05/11/2008, 05/12/2008) and wish to display them like:
05/07/2008 05/08/2008 05/09/20085/
05/11/2008 05/12/2008
and not like:
05/07/2008
05/08/2008
05/09/2009
05/11/2008
05/12/2008
Thanks for the help in advance!

The DateTime class has a DayOfWeek property. you can display your data anyway you'd like, are you asking how to work out which days are in the same week, or how to display that data ? What are you using to display it now ?

I want to display which days are in the same week. I am using a SQL statement to pull the attendance information from a database on a server but just want to group the attendance records into weekly groups. I am throwing the information into a list box.

OK - so this is a SQL question. I am not sure how to do it in your query, if you don't have the day of week already. I recommend asking in the SQL forum.

Try this, daetpart is your friend - from BOL
SELECT
DATEPART(wk,datadate) Week,
COUNT(*) Attendees
FROM MyTable
WHERE DATEPART(YEAR,datadate) = 2008
GROUP BY
DATEPART(wk,datadate)
ORDER BY DATEPART(wk,datadate)

In SQL Server Datepart(Week,{date}) gives you teh week of the year, so you could group like that.
eg
select datepart(week,getdate()) for today gives yuo 20, i.e. the 20th week of the year.
Hope this helps

i have apllication with forms created in design view.
this forms have controls in them, like datagrids, buttons etc.
my application reads text from a CSV file and putting the text in the datagrids and other controls.
these controls use the "arial" font.
my CSV loads both hebrew text and russian(not in the same time).
i have no trouble viewing russian. but when i switch my regional settings to hebrew, the datagrids display russian charecters(scrambled) instead of hebrew.
ive noticed that when i select a font in the form or buttons it gives me the option of choosing also the right script for the font.
but in the datagrid i can only choose the font name and dont have the option of script.
anyone knows how can i deal with this font problem?
thanks.

If all your buttons fire the same event, you can cast the object passed into the click event ( typically called 'sender' ) to a button, and then you can examine it's name or tag to work out what button was clicked and change the behaviour accordingly. I'd typically use the same event handler if all the buttons did roughly the same thing, for example, if three buttons all added a different value to something, I'd store the value in the tag property.

It doesn't come with the Express editions, as far as I know. I could be wrong because all I have is the Team Suite, which comes with everything.

I doubt anyone will willingly post you the code but a simple bit of research will get you the following

About the 8th result was a CP article - try doing some work before requesting the codez.

I've been trying to get this to work for ages now.
All I need is to be able to cast an object as a data type that's type is stored in a variable. EG:
Public Class Test<br />
Private _myType As System.Type = MyCustomClassHere.GetType()<br />
<br />
Public Sub DoSomething()<br />
<br />
Dim MyVariable As (Here it would refer to _myType to get the data type [which is MyCustomClassHere's Type])<br />
<br />
End Sub<br />
<br />
I've tried using DirectCast(), Converter(Of Object, Of _myType) and alsorts but I can't get it to work. Could anyone help me out? Thanks.

If I get what you're asking, I'm sorry to say that you've been wasting your time. This won't work at all since the compiler needs to know what the type is at compile-time. The best you're going to be able to do is define it as Object, but then you lose all ability call methods and st properties on the object.

Why? Can you tell us why you are trying to do so? What are you trying to accomplish? We can then provide you either with a resolution to your problem or provide you with alternatives.
Sometimes when something does not work, change your strategy instead of trying over and over and wasting your time.

Hello!
My aim is to read inputs from a gamepad that is attached to an usb port. How can I do that in Vb.Net? HOw can I also check the device capabilities?
Thank You!

You'll have to use DirectInput in the DirectX library to do this. There is nothing in the .NET Base Class Library that will do this for you.

I've never used it myself, but I know there's some support for hardware in the Robotics Studio Microsoft put out. No guarantees, but if you're determined to stick with VB that might be a starting point.

Merging cells is not supported. You'll have to use a third party grid control to do this, like DevExpress's XtraGrid Suite[^].
