Call a function from a standard dll

[sskanna82]

Hi,
I do not like to use the ODBC connectivity for SQL Scripts running process,Instead of that i want to create a vb.net based dll for SQL scritping process. But i dont know how to Call a function from a standard dll with advanced installer setup. It am not clear about the below document reference in Advanced Installer.Any can suggest how to acheive this?

Call a function from a standard dll
This predefined custom action can be used to call a function from a dll. Unlike native dll custom action where the function you call must have a predefined signature this custom action allows you to call a function with any signature. Use the Edit Function dialog to easily describe the signature of the function you want to call (the result will be shown in the "Action Data" field).

Hello,

Please note that managed code custom actions are not supported by Windows Installer. You will have to use unmanaged code to build your custom action in order for it to properly work with you installer.

hi

Is there any way to access .net dll or .net weservice from advanced installer.

.Net Installer Class action ???????

[GabrielBarbu]

Hello,

You can try using the .NET Custom Action to achieve this. Note that you will need to implement certain methods of the Installer Class in order for your custom action to function properly. More details can be found on this page.

Hi

I have gone through your link . its really good.
But my requirement is something different.

I have .net Window application,
.net dll,
.net webservice

I have to use advanced installer because I need to add many dialogs in my setup file
one of them have a combobox which will be populated by a webservice call.
After installation I need to call another webservice method and the .net dll method
to perform some activity.

Approach I have taken :

I have create a professional project pointing to my window Application.
Using Custom Action wizard I have setup the custom action ( Point to the dll and the function )
but when running it is giving an error message "function not found in the dll"

Please response as soon as possible .

Hi,

In a Professional project you can change only the installer theme by using the Global Properties page. If you want to modify the installation dialogs you can use only an Enterprise project.

well.....thak u


Now in my custom action section I have called an Exe in Commit

Exe is working fine but when I am closing the exe it gets an error.

System.InvalidOperationException: Could not find default endpoint element that references contract 'SASPServiceAPI.Service1Soap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

Exe is calling an webservice ....websevice calling is ok ....It shos a list of data and it updates a db table .....but when I am trying to close the form it shows the above error

[Moumita]

I have attached my the exe in commit action ........
but what i have observed that exe is called two times ...why ??????

Hi,

Exe is working fine but when I am closing the exe it gets an error.

For EXE custom actions any return value different than 0 is interpreted as failure. Most likely the EXE you are launching is not returning 0. You can try using the "Synchronous execution, ignore return code" option in the Custom Action Properties pane.

have attached my the exe in commit action ........
but what i have observed that exe is called two times ...why ??????

I'm not sure why you are encountering this behavior. Can you please send us the .AIP (project) file you are using and a verbose log of the installation to support at advancedinstaller dot com so we can investigate them?
