View Full Version : Pulling Data from Standard Dialogs

07-18-2005, 02:09 PM

I am working with InstallShield 11, MSI Project and I am writing some custom InstallScript code to pull the SQLSERVER name and the User Name and Password from the SQLServerSelectLoginDlg. I have customized the standard dialog by giving the Text fields better names DBServerName,DNUserName, DBPassword.

I am using the following functions to pull the information


Since I cannot return a string value from these functions, I am assuming that I should use the string variables szDatabaseName,szUserName and szPassword to get the values from these fields. Am I correct in this assumption? Is there a better way of accomplishing this?

I am extremly frustrated with this stupid scripting language.

Any and all help is appreciated.

You can use MSIGetProperty to retrieve the server name and other properties once they have been set on the form. The syntax would be

MSIGetProperty(hMSI, "IS_SQLSERVER_SERVER",szServerName,nBuffSize).
and so on for the Authentication Method, User Id, and Password

The scripting language is a little hairy, but keep in mind that a lot of what IS is presenting in the dialogs are being stored in MSI properties, and you just need to pull the values out of those properties.

Ive got the code setup in a seperate rul file that my setup.rul is calling. WHen I complie the file with the function, everything compiles fine. However, when I include the file in my setup.rul, i get errors that say:

"MSIGetProperty : undefined identifier"

I know that I am missing something, but im not sure what. Any thoughts?

My bad, the correct syntax is nResult = MsiGetProperty(hMSI,szPropertyName,szPropertyStr,nBuffSize)

if Nresult < 0 then there was an error retrieving the property

You also need to make sure you have #include "iswi.h" in your rul file.

The Windows Installer help gives more information on how to use MsiGetProperty and MsiSetProperty
