The "default mail program" does not impact MAPI -- it is a user setting, while MAPI provider is, unfortunately, a system setting.
First, see if System.Web.Mail will get the job done for you -- if it will do what you need, use it. I have not used it with Thunderbird, so I don't know if it will call through. If System.Web.Mail won't get the job done, then try Collaboration Data Objects (CDO), and verify it won't get the job done. If CDO works, it will be a better choice than MAPI. It gives you an object model, etc. and doesn't require nasty p/Invoke calls.
The MAPI32.DLL switch operates based on these registry keys (source: Platform SDK)
HKEY_LOCAL_MACHINE\Software\Clients\Mail\(default)
HKEY_LOCAL_MACHINE\Software\Clients\Mail\Provider1
HKEY_LOCAL_MACHINE\Software\Clients\Mail\Provider2
HKEY_LOCAL_MACHINE\Software\Clients\Mail\Provider3
Where Provider1, Provider2 and Provider3 are MAPI providers.
Underneath each provider, find the following:
(default) -- this is the display/text name of the provider
DLLPath -- this is the file name (without a path) of the DLL
DLLPathEx -- this should be the fully qualified path
MSI* -- information to do the install
Also check for these registry entries, which can overide the MAPI used for specific applications:
HKLM\Software\Microsoft\Windows Messaging Subsystem\MSMapiApps::exchng32.exe = ""
(route call directly to Mapi32x.dll)
HKLM\Software\Microsoft\Windows Messaging Subsystem\MSMapiApps::msspc32.dll = "Microsoft Outlook"
(route call using Microsoft Outlook key under HKLM\Software\Clients\Mail)
Also, try this (from platform SDK):
In the event that an application overwrites Mapi32.dll, you can restore it using Fixmapi.exe. Fixmapi.exe can be found in the same location as the stub library itself, usually C:\Winnt\System32 for Microsoft Windows NT version 4.0 systems. This utility copies the current Mapi32.dll (the new DLL that overwrote the stub library) to Mapi32x.DLL, and then copies the stub image, contained in the Mapistub.dll file, to Mapi32.dll. There are no arguments for Fixmapi.exe.
If the MAPI DLL was provided by Netscape or Eudora e-mail clients, the DLL is renamed to Nsmapi.dll or Eumapi.dll respectively, and the appropriate HKLM\Software\Clients\Mail subkey and DLLPath value are created. The DLLPath value points to the renamed DLL because neither DLL supports extended MAPI calls, so the DLLPathEx value is not needed.
Again, if at all possible I would go with System.Web.Mail or CDO. These should "do the right thing" and correctly route through Thunderbird or Outlook. If it is not possible to route through these implementations, and you do have to call MAPI directly, then I would probably allow the user to select a provider from the list.

First, my understanding is that system web mail does not actually open your default mail client but sends the message itself. I'm not sure about CDO. I'm trying to replicate the action of the Send To/Mail Recipient found in Windows Explorer. It's what we want.
As for my MAPI setup everything you spoke of looks correct still it doesn't work.

Well, I tried uninstalling and reinstalling and recreating the accounts in Outlook and I still can't get Outlook to come up when I select Send To/Mail Recipient. Let make this even simplier. Just get me that. I don't want to program anything any more. I want to make Send To/Mail Recipient bring up Outlook. Can anyone tell me how?

Apparently it does. I'd tried changing the default mail program using use Start/Settings/Control Panel/Internet Options many times and it didn't work. But after I used the "Set Program Access and Defaults" icon, located in the Start menu somewhere and in the "Add or Remove Programs" tool in Control Panel to set the default mail program to--as Outlook wasn't an option--Outlook Express things started working.
Now using Start/Settings/Control Panel/Internet Options I can change my "default mail program" and the mail program launched by my vb program via mapi changes as does the mail program launched by Send To/Mail recipient in windows explorer. I haven't been in "Set Program Access and Defaults" since. Just use Start/Settings/Control Panel/Internet Options. I've changed it from Outlook to Thunderbird and back several times w/o rebooting or even closing my application and whatever I select as my default mail program is the mail program that is started when I click the button to send mail in my program.
Why this works and why it wasn't I don't know but my experiences clearly show changing the default mail program in Start/Settings/Control Panel/Internet Options will change the mail program started by mapi (at least as it is used in my sub). Further my experiences strongly suggest that microsoft uses mapi the same way as I do in their windows explorer send to/mail recipient functionality.
Anyway, thanks for the help and I'm working good now.

Hi,
yes you can set the properties of that at the runtime in the OnItemDataBound event of the datalist. If you are know it that whether the image is landscape or portrait then depending upon the condition it can be set.

You are injecting text directly into your SQL string. This can compromise the security of your database and your application. You should, at least, use parameterised queries. See SQL Injection Attacks and Tips on How to Prevent Them.[^]

It is a free component provided by Microsoft, but I find most of client doesn't have this component.
For easy maintainance, I hope this component can embed to my application.

There are 2 forms, named as form1 and form2
form1_onLoad
dim a as new form2
a.showDialog(me)
when the form2 closed(dispose), the focus will back to form1.
The case is, after form2 dispose, the screen will refresh shortly.
I have tried a lot of time, it seems that my application will minisize in a shorttime and then show the form1.
How can I remove the "refresh" ?

Hi,
If I have understood correctly then you want to add some item to the combobox at dynamically, if so then you can use
ComboBox1.Items.Add("name")

i cannot because an error occurs telling me:
CANNOT MODIFY THE ITEMS COLLECTION WHEN THE DATASOURCE PROPERTY IS SET.

Hi Adrian,
It seems that you can't an item to the combobox once it has been assigned the datasource for it. So one solution could be to add whatever item you want in the datatable itself and then bind it to the combobox.

(The form webbrowser.vb will be open already. if not I want it to load)
In the end we're all just the same

Do a few searches on google, you'll work out how to build a search URL.
