Hi

:confused: could you be more clearer on what is that you are looking for? You want a DLL to execute inside what and a New form in What ..... ?????

We need integrate some visual basic projects, and we think do it, using instructions from a dll Activex module. Can this do it?.

Thanks

Hello, community..

Answer to previous messages with an example.

I have 2 Business Applications, Inventory and Account, and we want integrate their executing from the same window.

For that, I created a New Exe Project VB, with an MDI Form inside and added it a New Exe Dll Activex Project. Finally I have the following VB Project Structure:

|Project1
| |____MDIForm1(Form1)
|Project2
| |____Class Module
| |_____Class1

Now, I change Project2 like initial Project. After, I designed inside MDIForm1(Form1) 2 buttons, BInven and BAcco. We want, the instructions of the class1 module, invoke for:

1.- Execute MDIForm(Form1) first.

2.- Execute 2 external systems. The first one Inventory.exe and the second one Account.exe for each MDIForm(Form1) button, BInven and BAcco.

3.- Convert them, in MDIChild of the our Principal MDIForm1(Form1).



That is our need, for now. How I Can do this (examples please) ?, Is possible, development this Idea?
:confused:

I resolved my need. I found in the google spanish group the answer. I annexed the original visual Basic routine for you, if you need it. It isn't exactly answer, but help us.

Bye
