Hello everyone!

I would like to start by saying thanks to everyone who takes some time to view this thread and try to help.

My problem is quite simple to describe:

I have created an edit control with resource editor ( I use ResEdit, since Visual Studio Express Edition doesn't provide one ), and have tried to paste some text that I have copied from Notepad, but nothing happens.

If I type some text into edit control, then select that text, so it is highlighted, and try to paste, the text disappears and only flashing caret remains.

I have tried with checking the "Accept Files" flag in ResEdit, yet it didn't work either, as I expected...

EDIT #2:
**************************************************************

I have discovered the cause of the problem:
Mozilla Firefox blocks paste operation when running~~, but after I turn off Firefox everything works fine~~.
I don't think it is Firefox, but the problem starts when I turn it on.

After working in Firefox for a while, and closing it, the problem remains.

All other programs ( Notepad, Word ... ) work fine, it is just mine that has problems.

By the way, edit control was created in dialog box, yet when I create edit control via CreateWindowEx( .. ), the problem still persists.

Only after I restart my computer, and restart my application, does paste work fine.

IMPORTANT:

This behavior is typical for ALL programs that I write.

That is all important information I have managed to gather, I will post more if I find anything else.

I use VS2010 Express and just tried this and I can Copy, Cut and Paste from and into my edit control. Can you show us the resource script for your dialog (please use "Improve Question to paste it above)?

MyOldAccount 21-Jun-13 19:44pm

I have discovered the problem:it is Firefox,when running it blocks my paste function,but when turned off everything is fine.Can you help please?

Jochen Arndt 22-Jun-13 3:38am

A curious problem. I don't think that it is sourced by your program if it does not perform some kind of clipboard manipulation. You may use a clipboard viewer program to see what is on the clipboard. Such a viewer can be found here at CP: http://www.codeproject.com/Articles/168/ClipSpy

Solution 1

You certainly can copy, cut and paste in all edit controls, and it is true for all similar controls on all more or less modern OS and UI libraries I tried so far.
I think that your problem is just the artifact of wrong way of experimenting/testing. For example, when you complain that you highlight some content and then operate "Paste", having an empty content is quite a correct behavior if your clipboard data currently has empty data of required clipboard data type. This is actually the indication that your paste functionality works, otherwise you would see no changes in content. You don't need to highlight anything to paste content; it would be inserted somewhere, depending on insertion point. You can select part of content, do "Copy", and then "Paste", then you will see the effect. I would advise you to learn using the system as a regular user better, to start with.

Maybe you were right, maybe it was wrong clipboard data type.
My 5 anyway, for your suggestion.

MyOldAccount 21-Jun-13 21:17pm

I apologize for rejecting solution.I have found a cause of my problem:It is Firefox.When it is turned on it blocks any paste function in my program.Can you help me please?
Thank you.

Sergey Alexandrovich Kryukov 21-Jun-13 22:33pm

No, because I also use Mozilla, and it does not block anything. Such blocking across different processes is almost impossible and would mean the level of abuse which could easily be dubbed computer crime. Sorry, but I cannot believe that your observations are correct. This is also confirmed by your original question where the problem is the incorrectness of your observation.

Still, when I use my program, paste works fine, yet when I turn on Firefox, I can't paste.
After I turn it off, my program works fine again.
I have never said that it is Firefox to blame, I just added this info to help people to help me with this.
Still, I will understand if you can not solve this.
Thanks anyway.

Sergey Alexandrovich Kryukov 22-Jun-13 1:30am

Hm...

MyOldAccount 22-Jun-13 3:06am

I have updated my question, in section "EDIT #2".
Perhaps this will help.

Solution 3

After battling this for more than a month, I have decided to take my friends Windows XP, and do a full clean installation.

After that, the problem seems to have disappeared...

Hopefully it will stay that way :)
