Win API doubt

9 posts in this topic

Hi All

I have question regarding Windows API.

I am trying to build small automation of copying one file from open folder to two different folders. I am doing this using mouse and keyboard events (basically searching windows by title and then copy).

My code should execute first copy command and then should start working for second copy, since file is quite large it is stuck there and control is not coming back to the code.

i tried putting in delay. Is multi threading a solution ? Any help or direction to any guide will be much appreciated.

Background: I am using VBA to do this, Posting on this forum as autoit source will have same functionality.

Regards

VBA is a completely different language to autoit, and so while it may have similar commands, it is not the same, and therefore this should go into the developer chat board under General.

not able to post in developer sections. some restriction or something.

Can you tell me how does autoit resolve such dependencies, does it give delay or something and how does it handle controls..

and also if you can post my problem in developed section..

If you want to perform copy operations in the background then take a look There is an example in the first post for copying multiple files.

An alternative is to use more than one process. Multithreading is not possible in AutoIt, but if you run the cmd command (which I assume you can do from most lanaguages) then you can run it as a seperate process. To do that in AutoIt look at the Run function and the @ComSpec macro (there is a section in the Run docs about using it). If you store the PID then you can use the ProcessExists function to check if it is still in progress.

Hi mat

Thanks for your help.

Basically i want to implement this in Windows API, First i will open folder "AB" using title search and then copy folder on location (600,400). Now i seach "CD" and paste at (400,600).Now i search for folder "FG" and copy folder at (600,400) and then come back/paste at "CD".

Problem i am facing is - i reach "AB" i copy the folder and then i goto "CD" and run paste command, everything works perfect till here. Now my source code execution is not taking place.

I tried to debug, debugger stops after first paste operation.I beleive we need to exchange controls using PIDs or somthing.

I am posting this question here because i believe Autoit Source code will be implementing this functionality (can you just give me hint or somehing).

Regards

This discussion is going nowhere without the code you're trying. Post something we can help debug. But don't expect anyone to implement your idea for you, there's plenty of examples (and probably a UDF or two) to do exactly what you want.

This is an AutoIt forum so we will help with AutoIt code. Assuming the code you posted is VB then you need to ask on a VB forum.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

sure i will post this on VB forum , i was thinking you guys may be helpful since Auotit is nothing but implementation of WIN API..

anyway thanks..
