loop It takes a long time for find text box Id number and sendMessage to that...

There is a faster way for find text box or find other controls id and sendmessage to that's?

Maybe provide some more information? Did you write this app? Why do you need to do this?

You can find child controls with FindWindow...

Intelligent and speed up the work
An organization has changed its Application Storage.
New software is written with C#.
The information contained in previous software all need to re-enter the new software.
In this application,Page where Add the product to inventory goods warehouse There is Has several fields.
The information to be entered in the fields, in a text file is available.
Such that The information contained in each line of text file must enter to a field.
We do it automatically To speed up the work.
There is no problem in reading text file lines,But the main problem here...Read the value of each line of text file Must enter This program in various fields...
And since the number control & HWNDPARENT is varies.in my section code has a loop so It takes a lot of time to control handler is found...
After finding the control HWNDPARENT each line of text file must enter to a field.

We have problems in doing so:

1-It takes a long time to find all HWNDPARENT controls and we do not know where we continue to loop for found all controls!
2-Can not obtain the name of each control
If the program was written with vb6 we can found control text but this application it was made with C#,C# Controls have Control Name and i can not find control name but can found vb6 control text...

3-What we want to do:
read line ONE of text file & Write to Control With Name 'ProductName'
read line TWO of text file & Write to Control With Name 'Stock'
and ...

4-Autoit how show controls Instance,Can be found control by Instance or TabIndex?

a question:
GetDlgItem Found control by ID.
Can be found control by Name and after that write to that control value?
If yes How?
the problem is solved If this can be done

https://blogs.msdn.microsoft.com/old...21-00/?p=42833 hints that you need to use WM_GETTEXTLENGTH+WM_GETTEXT and not GetWindowText.

Down ↓ Code Return Initial Value Text Box The programmer Entered To The Text Box:

System::Call "user32::GetWindowText(ir1,t.r2,i${NSIS_MAX_STRLEN})"

i test WM_GETTEXTLENGTH+WM_GETTEXT
System::Call 'user32::SendMessage(i $1,i ${WM_GETTEXT},i ${WM_GETTEXTLENGTH},t.r9)'
that Return The Value Which Are Now In The Text Box....

But I Want Return Control Name...
But I Don't know How!
Such As Autoit

Name is not something a HWND has at the windowmanager level.

That tool might be using Microsoft Active Accessibility (MSAA) and/or UI Automation (UIA), IAccessible::get_accName perhaps.

You could try https://www.codeproject.com/Articles...-Accessibility and see if the Name there is the same thing.

However, this forum is not a general programming forum! When dealing with stuff like this you should first write it in some language you know (VB? C#?) and then (and only then) if you have problems doing the same thing with System::Call should you ask here on the forum.
