Taking a current screen_print

Hi Iain,

think I've seen a note on the internet about screenshots activated from uniface.

It was on good old T.U.R.F.

Maybe a simple "SENDKEY" can do the job ??

Success, Uli

Yeah, but the bit on Turf is the question without an answer, all that really tells me is that I am not the only one with this requirement.

What is "SENDKEY"? It's not a uniface command.

Andrea stated on TURF:

Maybe you prefer a tool.
ZapGrab is light and easy and do the work.

Think this can be the answer.

Sendkey is a way to simulate keystrokes to all kind of windows handles (some old DDE ways for remote Control).
So you have a remote option for the "SHIFT+PRINT".

Uli

ZapGrab requires the user to highlight the area they want to screen capture.

I just want to capture the current window, save it as a bitmap or jpeg, load it as a string into my component and include it in the web-services call so I can attach it to the support log internally.

No user input should be required.

And how does one access "SENDKEY" from within uniface proc? Is it some kind of executable?

I need something similar. Screendump of current window (or better a specifeid area) to a bmp file. Anyone tried to wrap some Windows functions in a simple dll that I can call from Uniface?

Have a look at: http://www.codeproject.com/search.aspx?q=screen+capture&x=0&y=0&sbo=kw which offers a variety of ways to capture a screen from an application

I enriched the USEQREAD.DLL with an option to invoke the "print screen". you can download the DLL plus a description from uli-merkel.de as "dITo project SEQREAD plus - how2test.zip" after you have installed the DLL, you can simulate pressing "print screen" by perform "M4LS_CATCHSCREEN"

I tried Uli's DLL. It works great simulating Print Screen ! But we always want more: Simulate Alt Printscreen for current window. Give some coordinates as parameter so we can pick up a section of the screen Option to save to file Some way to put the captured image in a Uniface field

Hi Theo, based on the code I documented, I think it's possible for you to add a "ALT-Printscreen" variation. For all the other luxuries, I think it's best to install a proper screen-capture tool which is activated with pressing printscreen.

Hi Uli, Using an external tool that reuires user input is not an option. I am playing with an idea for a low cost/no cost GUI test tool automated test tool for regression testing GUI aspects of Uniface applications. Not a serious project for me at the moment but I have started to collect information, tools etc. Theo

Hi Theo, well, you have the screen in the clipboard as a base to work from. And I added perform "M4LS_CATCHWINDOW" so you can get the Uniface window as well. (Downloadable from www.uli-merkel.de). Now all you need is some graphic tool which accepts commands from a scripting tool to do what you want. There is no need to reconstruct this, have a look whats available in the different marketplaces. Or you can use "automatisation" on MSPAINT to save a file you got from the clipboard (and manipulate the image as well) as decribed here: http://community.spiceworks.com/scripts/show/793-screenshot-emailed-to-in-one-click In general: using uniface to launch PowerShell Scripts my be a way to do all these jobs.
