Cool-LV

Hello All,

I wanna disconnet/connect the network with LV, call with API or .net to realize ? Please help to give a tip or thread, thanks in advance.

Hello everyone, attached is a MP3player_Sample that plays format MP3 and WMA files. Just for your fun. :laugh: :laugh: :laugh:

Hi,

Nice interface, but I can't open MP3player_Sample.vi ,even I re-download the Zip enclosed file twice, My LabVIEW is 8.2.1, and the other Subvi works fine, what happenned ? anybody met this condition ?

question solved, I use "System Exec" to realize.

Hello all,

Anybody knows how can I set the XP to different Theme programmable ? I don't like to double click a *.msstyles file to reach that function. thanks @!

hi,

see if the dll and vi works for you

cosmin

thanks cosmin, but the vi is much new, mine is LV7.1 .

Here it is:

Thanks, it is what I need basical ,but there are not " last accessed information" still, en......

So how did you end up doing it? Please share your findings with us :thumbup: It's only through the sharing of our triumphs and failures that we learn for each other...

Hi,

I use "Block input" to disable keyboard and mouse function, and "Sendkey" to do the send key, I remember that I issued a topic here which is sendkey function no response, that is what my goal is.

Thanks all, the goal that I got !

Hello!

The OpenG.lib has a VI for this: file.llb\File Info__ogtk.vi. It works also with folders.

Hi,

Thanks for your thread, and I can't find "File Info__ogtk.vi" in the OpenG.llb (even I downloaded this toolkit yet), and I searched it in my disk, can't be found also. can you help to enclose this vi here for me ? thanks @!

Hello,

As the subject, that I want to get the information from selected folder/files, and get its created, last accessed time information, how to do this ? thanks in advance !

Use the "<This VI>" > "Panel Close?" filter event in an event structure - this is what the help has to say about it:

Crelf,

Yes, that is what I need. :thumbup: I know there are this event long ago, I don't know why I forget it this time. I believed in that I should call API to realize .

Yup, this handle is so easy. thank you !

Hi,

How can I get the info/feedback after user click close window button ? and I would like to use Windows' original title bar (don't wanna to make a dummy bar). the goal is that user click close button to close the window, and I want to get this info to ask user, "are you sure to quit out of this application!" thanks @!

The wallpaper (eventually) has to be a BMP. When you are manually setting a JPEG, for example, as your wallpaper, Windows actually makes a copy of this to a BMP format and uses that for the wallpaper. Check out the 'Wallpaper' and 'ConvertedWallpaper' regisrty entries under HKEY_CURRENT_USER\Control Panel\Desktop.

Oh, thanks, to be this ! I know now.

this VI calls the SystemParametersInfo function from user32.dll.

Thank you very much, Yup, this is what I am looking for, but it since support BMP image only ? fail to JPEG picture.

There are properties on the Pane class in VI Server that you can use to get/set the wallpaper. They are Background Image, and Background Mode.

E.g.

Hi Akash,

Thanks for your answers, Maybe I havn't given the details, my wallpaper isn't LV front panel background image, but it is computer's destop wallpaper.

and your thread is supported at LV8.2, mine is LV7.1 (I can't find your thread at LV7.1 and LV8.0) .

Hi,

Anybody knows how to set an image as a wallpaper programatically ? thanks @!

I want to add some items into Internet Explorer's Popup Menu, Such as "do my program", after click that item, my application Program should start running and response that click.

I know I can Edit the Registry to add items to Internet Explorer's popup Munu, But how to bind this item with my Application Program based on Labview??any idear?? thanks...

Hi,

I think this is not LabVIEW query issue, en, you must write a htm script (engine) to direct your application (*.exe), the handle that you can see some examples, e.g. "Flashget" .......

question solved. and I found, there are not only 8 digital write and 5 Digital read, they can be 11 DIO(read and write option), and 5 Digital read only.

hi all,

using "Port out.vi" is successful to control digital signal out corresponding, but I am fail to use "Port in.vi" to read digital signal back. read from "FAQ Moderator's tells" that the read pins is Pin15, 14, 13, 11 and 10, but I connect 5V signal to them between ground (short pin 18 to 25 as ground), there are no response at labVIEW, anything that I am wrong or any focus that I should pay attention to ? thanks @!

You can use your parallel port as a free little DIO card! You get eight bits of output and five bits of input.

If you can determine which address your port is using, it is a simple matter to use the "In Port.vi" and "Out Port.vi" (except on WinNT) to read from and write to your parallel port. WARNING!!! Be careful not to short anything out, as this port is built in to your computer, and inadvertently touching the wrong pins together for just a millisecond can destroy your port! These pins, as output, can only drive a tiny amount of current, so you would need additional circuitry to drive relays. I recommend buying a parallel port card, which are only about $20, just to be safe.

First, you need to determine the port's I/O address. In Win95, right-click on "My Computer", select Properties, then select the "Device Manager" tab. Click on the + sign next to Ports, the double-click on any "Printer Ports" you see. Clicking in the Resources tab of the window which comes up tells you the I/O range, in hexadecimal. For the more primitive Windows, try these addresses (all hexadecimal): 0x378, 0x278, then 0x3bc.

Once you know the port's I/O address, "In Port.vi" reads eight bits, and "Out Port.vi" writes eight bits. Take advantage of LabVIEW's ability to display any numeric in hexadecimal format (under the "Format & Precision" menu) and show the radix on your numbers lest you forget. Show the address as hexadecimal, and the data as hex, octal, or binary, for easier interpretation.

Here is the relationship of pins to bits on the 25-pin connector: Pins 2 through 9 correspond to output bits 0 (LSB) through 7 (MSB). Pins 15, 13, 12, 10, and 11 correspond to input bits 0 (LSB) through 4 (MSB). Pin 11 in inverted. Most connectors manufactured today have tiny pin numbers embedded in the plastic next to the pins.

If you want to know more, there are plenty of parallel port FAQ's on the internet.

During the power on self test (POST) some BIOSs scan ports to check to see if they're installed. On one machine I had the situation where the external hardware was setting the IO lines such that the BIOS was not seeing the port (hence LPT 1 was not installed and no printing was possible). If this happens, make sure that your external hardware is disconnected when you reboot the machine.

Hi FAQ Moderator,

And I can control the parallel port data out, can control my relay open and close normally, but it can't read digital signal, for example +5v signal,and I use "in port.vi" to read the signal status, connect the signal to the pin10 or between the other 10 to 15 (except pin12) pins, and ground, but hasn't any result feedback, any wrong or focus that I should pay attention to ?

Which I appreciate greatly.

Thank you Joe for taking the lead on that effort! :thumbup:

Thanks all, the link Excel toolkit is so cool. great !

Hello all,

As the subject, I can combine two words to a new word paper, but, I can't do it at excel, who knows ? thanks in advance.

You can use an array of Cluster that include diffient controls(any type control you wanted!), and then customize the cluster and the array, make them frameless and transparant background and foreground. then you can use the property of the array --NumRows to control how many lines to be shown, IndexVals to control the beganing displaying line.

forgive my english.

the attached vi is an example that contain an boolean, a string, an numeric. it's an array of cluster, but if you don't know the diagram of it, you may be not know it's an array of cluster, :laugh:

Thanks keiran, your thread is good. but as the items I need much, I don't wanna display whole of them, if that array can added a scroll bar that would be perfect.

maybe sub panel can do this, but I think this is not convenience, and good looking, any good idea ?

Hello all,

can anybody give a thread to realize a facade showing like that Database sheet, add diferent control items at a list box, or list table effect, for example, string control, number control and ring etc, I know cluster can do this, but it is not convenience and beautiful. can ActiveX control insert an object OK ? but I haven't found that item yet, thanks in advance.

I can see the video correctly with the windows media player.

Sorry I don't know what hapens but I can't attach the video. So you should help me without my video!!!

Hi,

Have you tried the other AVI video file ? Do they open failed ? and I found your sample there are logical problem, why you put the stop button outside the while loop ??? and AVI reference not been closed etc.
