How do i change a property of a control in another app?

i have two apps written in vb. when the user has typed the correct user name and pass i want to send that info to the 2nd app which will email tat to a given address.

how do i do this. :confused:
i tried this with timers and registry it didnt work nicely.

There are many ways how apps can communicate. Some more, some less efficient.

For example. You can use Winsock component. One app can open a socket and listen to it. The other one then sends a message.

Btw... you cannot change Control's Property from another app directly. You can however use some APIs but is quite complicated.

ok how do i do it with API. ive been told i can do it that way. any links or samples?

You could modify the second app to that it uses the Command$ function to accept input parameters (in this case the name and password). You could then Shell the second app from the first.

Here's an example:

App2.exe contains

Code:

---

Private Sub Form_Load()

Text1.Text = Command$

End Sub

---

App1 does this

Code:

---

    Shell "C:\temp\app2.exe hi there"

---

When you do that, App2 will show up with hi there in text1.text

yeah this will work only when the app loads. what about after it loads? i want to do his when both the exes are loaded on to memory.
