Take a look at this article[^] by Microsoft.

I don't think that both have been thought up simultaneously with a distinct idea "let's use A in circumstance one and B in circumstance two". You got a sledgehammer and a warhammer, both have similar uses but different advantages and disadvantages in different situations.

I have created a VSTO Excel addin. It's deployment is really a headache.
I want to set VSTO 2.0 RunTime in prerequisite but I am using VS 2008 and it shows VSTO 3.0 Runtime in prerequisite list. I can not select that because that will use .NET 3.0 or above. My applicaiton is .NET framework 2.0 compatible and it requires VSTO 2.0 not 3.0 as a minimum requirement.
How to set VSTO runtime 2.0 as a minimum requirement ?
I want that If any dependency is not found on client PC then either it should be download from internet(in case of .NET framework) or it should be packaged with installation (in case of VSTO 2.0)
|
|
|
|
|
Are all your projects set to use and compiled to the 2.0 framework?
To verify, go to the menuitem "Project", and select "Properties". There's an "Application" tab, and it should state that it's using the 2.0 framework in the textbox labeled "Target Framework".

Yes my both projects(SetSecurity & Excel Addin) in soltion are targeting to Framework 2.0
My setup project is also showing dependence "Microsoft .NET Framework" with version 2.0.50727
|
|
|
|
|
VSTO 3 isn't supported on the 2.0 framework, I hoped that the installer would drop everything that would require a newer version of the framework.
Can you uninstall VSTO3 (to make sure there's no references at all), building[^] the setup using VS2005 & VSTO2?

|

unfortunately it is not getting uninstall. On uninstall it crashes and shows "Send \ Don't Send". Any VSTO run-time cleanup tool available ?

Hi
I want types of layout in .net
please help me
|
|
|
|
|
You will have to be more specific as different technologies provide different layouts.
If you are looking for WPF layouts, see here.
Silverlight, too, provides different panels for layouts.

Hi there! I need some help with datagrid.
How to put a image\ico in the datagrid header column?
Thanks
|
|
|
|
|
One way you can do this is to use the CellsPainting event to draw the
bitmap for a particular header cell. Here is code that does this
assuming the bitmap is in an imagelist.
//this.images is an ImageList with your bitmaps
void dataGridView1_CellPainting(object sender,
DataGridViewCellPaintingEventArgs e)
{
if (e.ColumnIndex == 1 && e.RowIndex == -1)
{
e.PaintBackground(e.ClipBounds, false);
Point pt = e.CellBounds.Location;// where you want the bitmap
in the cell
int offset = (e.CellBounds.Width -
this.images.ImageSize.Width) / 2;
pt.X += offset;
pt.Y += 1;
this.images.Draw(e.Graphics, pt, 0);
e.Handled = true;
}
}

Thank you Jinal for the replay,
but that work for the DataGridView. I need to do that in a DataGrid, i have to use framework 1.1
Best regards,

I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin’s make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

Do you have an smtp server running at 192.168.1.15:808 ?
probably not.
You should use the smtp relay host that your isp has given you. (use the fqdn, not the ip-address) If you don't have mail at an isp, this won't work. (live.com does not provide smtp relay services). Also, your isp may limit the from: address, and may require authentication when sending mail.
|
|

|

hi their,u have told me to use fqdn instead of smtp
class n also u have mentioned tat "live.com does not provide smtp relay services" then which mail portal does support to send mails without any limitation or minimum limitation...
how do i find fqdn....?
could u give the exact coding to accomplish my task?
|
|
|
|

fqdn means fully qualified domain name. Try Google if you don't understand a word.
What you're looking for is an 'open smtp relay' (look it up before replying). Technically not illegal, but if you find one, your mail will probably be blocked by the recipient's ISP. Are you trying to get into the spam business?
You will have to set up your own smtp server if you want to send mail without limitations, but if you start spamming,
expect
1) Your Internet account to be closed down by your ISP
2) If you're really good at it, a visit from the Feds. (CAN-SPAM act of 2003).
If your intentions are pure, have a look at this list: http://www.iopus.com/guides/bestpopsmtp.htm[^]

i saw about fqdn in google ...
but my aim is not to get into spam business...its just for my learning only actually i wanna to develop a application just like outlook n i'm student so i'm wanna to learn it. i wan code for my gmail account....once if i go through tat sample code then i ll become much clear...could u post any sample code?if yes pls post it soon because i'm eager to learn it
