Remarks

To create a startup dialog you would create a form that contains the controls you want on the startup dialog. You also need to create a class that implements IStartupDialog. Write code for the DoModel method to display this dialog when the ArcMap application starts.

The following registry key is used to specify which startup dialog is to be used by ArcMap.

HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ArcMap\Settings
StartupProgID "Map.Start"

The datatype for StartupProgID is a string. The StartupProgID string is composed of two parts that are separated by a ".". The first part is the name of the Visual Basic Project used to create the startup dll (Do not confuse this with the Application Title of the project, which is found in the Project Properties dialog's Make tab). The second part is the name of the startup class. For example if you have a VB project called Map with a class called Start, then the ProgID would be called "Map.Start".

Instead editing the registry to set the StartupProgID, you can use the ArcMap user interface. In ArcMap, click Tools and then click Options. Click the Application tab. Enter your ProgID in the Startup script: textbox.

There is also another registry used to specify whether the startup dialog is turned on.

HKEY_CURRENT_USER\Software\ESRI\ArcMap\Settings
ShowStartup 0x00000001 (1)

A value of 1 means that the startup dialog will be shown on ArcMap startup; a value of 0 means that the startup dialog will not be shown. Note, this registry key does not exist unless you check "Do not show this dialog again" in the default startup dialog for ArcMap or uncheck "Show startup dialog" on the Application tab of the Options dialog.
