I have a complex custom dialog inside a DLL.
I want to call that DLL as a Custom Action if a certain MSI dialog page is displayed.
How can I start that CA?
I can trigger a DoAction event on a push button but I didn't found a possiblity to fire such an event on "InitDialog" or something like that.
My favorite solution would be to start the CA (and the dialog) when the MSI dialog is displayed the first time and unload the DLL (and destroy the dialog) when the MSI page is destroyed.
Any suggestion would be helpful.

Hi,
You can import your dialogs from DLL to the MSi project. Do this:
1. Compile MyProject.rc to MyProject.res with the following command-line statement:
>rc MyProject.rc
2. Build a DLL with the following command:
>link /DLL /NOENTRY /NODEFAULTLIB /MACHINE:iX86 /OUT:MyProject.dll MyProject.res
3. Open your .ism project.
4. Right-click the All Dialogs folder and select "Import Dialogs from Resource DLL".
Best wishes,

Hi,
your are right. But my goal is to reuse the whole dialog logic (message handlers etc.) and not only the resource of the dialog. ;-|

You need create and export from your dll function that create and execute your dialog. Then you need create custom action (i.e. type 1) and call this action from DoAction.

When you call custom action from dll each time this dll unpacked, loaded, called, unloaded and deleted automaticaly.

You can't load this dll at start installation and unload this at and of installation.

Another way - using casto bootstrap application (setup.exe) that load your dll, ru your installation package and at end unload your dll.


sorry my english...
