thanks for the file, after extracting the zip file

i have 4 folders,

clipboard

kernell - 32 dll

screenshot

user - 32 dll

should i copy all these into D:\Program Files\National Instruments\LabVIEW 8.5\user.lib, my os is xp prof.

and in the attached file, my installed software can be seen, are these enough for image processing functions, or should i install new tool boxes like in matlab,

Always thankful for your patience and kindness.

Hi hldn,

after extracting the zip file you can open the vi in the screenshot folder and use it. The only thing you have to attend is to be sure that all pathes to the dll are correct.

thanks but i got the attached error message,

0] how will i check that all the pathes to the dll correct,

0] will i edit these pathes, or move the files to that folders,

where can i find a brief explanation for this, and since i am very new in labview some more questions

1] i have found one more application for viewing analog sound by labview using the on board sound card waveio042.zip

my question is it possible to view the video signal like this by the help of tv card or graphics adaptor of the pc ?

2] if not i will try to use screenshot and image processing, the question is

how can i make this two codes , one for audio and  video , run one after another,

and also will i need extra sw for image processing by labview

best regards

Mike,

here is Johnny.

For my homework I have used your program "screenshot.vi", too. It works very well.

Can you maybe explain me, how works this program? I have seen, your programm call many windows-libraries, but I don't unterstand that very well?!

Maybe can you explain me this program step for step?


How lang have you already used LabVIEW? You are really an expert here! And I beginn to work with LabVIEW only for 3 weeks, I couldn't understand the flow of data so good.

Please forgive me with my so many questions, I hope I do not have annoyed you.
But it is very important for my homework, only in 3 weeks I must finish it. If you have time, please give me an example for the test protocol, too. Thank you very very much!

Hi Johnny,

with the first part you can select from which window you want the screenshot. In the example it is the vi. The for loop emulates the key combination to make a screenshot. Either "Alt" + "print" for the specified window, "ctrl" + "print" for the entire screen. The  clipboard vi read the image from the clipboard so that it can be saved, for example as bmp.

Hope it helps.
