Help with DDE

8 posts in this topic

Hello,

i'm having trouble with DDE (Dynamic Data Exchange)

i've read on the AutoIt Help thing about COM and using ObjCreate.. but i still don't get it!

well, i want to, just like autoit that it would run a certain program when opening a file.

i know how that works (open a map -> goto Folder Options -> Tab File Types -> add new one etc.)

but if i want the fileNAME of the file that i want to check... how do i do that?

like:

<right-click on a file> --> <run> --> <scan the selected file using fileNAME?> --> <done>

get it :)?

well please reply quikly or reply anything...

thanks

Someone correct me if I am wrong, but the following should work:

1. Open the registry with regedit.

2. Find your extension as '.ext' in HKEY_CLASSES_ROOT. i.e. HKEY_CLASSES_ROOT\.au3

3. Note the default parameter value of this key i.e. AutoIt3Script

4. Find the key named with the value noted above in HKEY_CLASSES_ROOT. i.e. HKEY_CLASSES_ROOT\AutoIt3Script

5. The shell key gives the default application. i.e. HKEY_CLASSES_ROOT\AutoIt3Script\Shell = "Run"

Once you know where to look, you can use the registry read functions.

There may also be a UDF to do this on the forums. If not, as this is Windows functionality, not AutoIt's, search the internet, not just this forum.

Your topic title probably did put people off. DDE is a freeking Norwegian pop band. Most of the people here have newer heard about them. I bet... Oh, Dynamic Data Exchange.... Thats probably not a pop band after all...

If fileNAME in this case is your autoit prog then the stuff posted by @stumpii should work. Or you could take a look at this

And at last does you script check $CmdLine[] array?

Now the big question why do you want DDE?

hmmm im now looking at the code you gave me,

but i want the DDE (not neccessary actually) to give the filename..

you can use DDE to make an object and there's some command that gives you the filename.. but i dont know which or maybe it DOESNT exists...

well, you can refind the DDE it @:

[open: My Computer] --> [Menu: Tools] --> [Folder Options] --> [Tab: File Types]

When you do this, you can create extra file TYPES. So i had created a new file TYPE named [.prg]

@Advanced, you can add new events, i've added an event and want to use a certain program.

my event was called [Run Script] with my self-made autoit program.

If u cross the [use DDE], u can use the DDE thing to give certain information about the file, but how do i get it!!!?

i can't be more exact, but i'm checking the script you gave me.. maybe it will help i'll see

I've just finished a generic UDF library for Windows DDE (client and server).

Here: DDEML.

UDFS & Apps:


DDEML.au3 - DDE Client + Server[*]
Localization.au3- localize your scripts[*]
TLI.au3 - type information on COM objects (TLBINF emulation)[*]
TLBAutoEnum.au3 - auto-import of COM constants (enums)[*]
AU3Automation - export AU3 scripts via COM interfaces
TypeLibInspector

@Immense

At my opinion your are not looking for DDE ?!

DDE is like loulou has stated in his script meant for data exchange. Meaning that when you drag a file to an Application it would open up that applocation and run the file. This is only 1 example DDE is of course more complex than that.

What kind of information are you looking for I can't see that in you post actually.

This will return the current association type linked to your ".prg"

File Associations
