vba Windows api - Save as Freezes Excel

[golemic]

I need help on this, i don't know much about windows api, and i'm trying to figure out how i can save a file, and overwrrite it (already exists with the same name).


What i am doing is find the application first, send some keys like alt, some down keys, enter.(file->Save as->Enter)
When i press enter, it comes a new window asking confirmation about saving the file.
And then excel freezes, with out finding Confirm Save As window and pressing "Yes".
It happens in command:

Call SendMessage(SaveButton, BM_CLICK, 0&, ByVal 0&)

Can anyone help me solving this. Is it happening because it focus is still in save as window or something?
Should i use other way to do what i want?

Why can't you use OLE Automation?

Thank you for your answer mr. Poulsom, and forgive me for my english.
What i'm trying to do, is through vba-excel save a HexEditor file, and overwrite it.
Is there a way to do it using OLE automation?

Sorry, I thought you were trying to save it in Excel.

Solution : I used PostMessage instead of SendMessage, for Save button control.
Thanks anyway!
