API VBA: Open Dialog

Is it possible to access this dialog through VBA. I just want to allow a
user to search for a file and then just get the full name including
directory structure to pass to a function.
Thanks,
Corey

Sure. Once you have a userform in your SW Macro, the menu selection Tools - Additional Controls should be enabled. This brings up a list, from which you can select Microsoft Common Dialog Control. This may not be installed by the VBA, but if you have VB on your computer, you've got it and can use it here.

i dont know about vba because its a chopped up version of visual basic. but vb6.0 and later. you can create a your own open dialog boxs. this is not a part of solidworks api but is a part of visual basic.

Common dialogs can be created as well by calling Windows API functions. For open dialog box, there is a function GetOpenFileName. In VB you would need to declare that function like
Declare Function GetOpenFileName Lib "Comdlg32" (lpofn As OPENFILENAME) As Boolean
You would also need to declare OPENFILENAME structure as defined in WIN api help, like
Type OPENFILENAME lStructSize as Long hwndOwner as Long ... etc End Type
Showing Open dialog box would need the following steps:
- Create an instance of OPENFILENAME structure - Fill in the required values - Call OpenFileName function - Read the selected file name and path from the structure
More details can be found by seacrhing MSDN, see msdn.microsoft.com. I don't know, however, if that can be done in VBA.

Here is a module I use for such things. It works in VB and VBA. It has file open, file save, and browse for folder dialogs. There is a "Sub Main" that demos some of the features, run that to get a feel for it. The "OpenFiles" routine allows for setting a non-local directory as a seed directory, as well as allowing/disallowing multiple file selections thru the dialog.
