Re: Application Builder for Labview 7.1
On my machine, LV7 does not load LV7.1 build file correctly. An errors pops up everytime it finds a chance. -Joe p.s. It is frustrating to keep multiple versions of LVs on a single computer. NI should at least consider to make the file format consistent among the minor versions of the same major version. p.p.s LV 7.1 does not work on Windows Me and 9x.

Re: memory allocation
Here are several tips I learned from experience, hope you find it usefull: A. Check if Array/String inputs are empty, if they are, skip the step (for example, concatenate string vi and build array vi). B. Use concatenate string and build array VIs sparsingly. C. Close unused references. D. when reading large files, read small chunk at a time. Other people may have additional tips. At the mean time, check the Application notes from Labview Help Search Labview Bookshelf Application notes and white papers Labview performances and memory management -Joe

Re: remote control
It all depends on what your needs are. To remotely access / controll a VI from outside your company, you need port forward, so the server is visible on the internet. Normally your IT needs to be involved. If you want to publish / control the vi through webpage, then the labview webserver must be running, you might need the internet toolkit as well. If you want to control the remote computer in addition to controlling the VI, you can try some remote control software, such as UltraVNC (free but less secure) or Radmin (secure but not accessible through browser). You might also try out the remote panel in Labview, which also allows your to control a remote vi. Hope this helps. -Joe

Re: How do I get a print dialog window ?
Someone might have better answers, however, here is my 2c. To Q1, I use an application called fine print, when it set as default, it will popup everytime when there is a print opeartion and you can choose what printer to print to and set other settings as well. You can preview the print content as well. It is not free, but a very good tool. If the report generated is a word or Excel file, I believe you can use print function in either word or Excel to print. You will have more options as well. To Q2: Programetically it is not possible to directly print a graph to printer in Labview, but there are other ways. Whenever we want print lots of graphs or plots, we use a very powerful graph tool called ProEssencials. You can select which printer to use, you can export the graph to different images (jpg, bmp and emf). When plot is sent directly to a printer, you can maximize the plot without loosing details (unlike labview graph, which you capture a piture of the graph but the picture is not scalable) Hope this helps, -Joe

Re: How to determin wich control has focus
Sometimes when you dialog controls, the last OK button added to the front panel has the focus turned on by default. You can right click on the control and select Customize Key Navigation and select None in the list. It seems you have a different problem and are using event structure. Nomally we use the Value Change as event condition. Is it possible that you may choose a different condition, such as Key Down, Key up, etc? -Joe
Re: saving excel files using report generation toolkit
It seems like you already doing it, but not complete, you need to close the report reference by using Dispose Report, one of the input for this VI is Save Change?. -Joe
Re: How accurate is the wait function when using really long waits?
You can always use a smaller wait (either wait or Wait Until Next ms Multiple) in a loop so your VI does not lock up (no response from clicks), and count how long the vi is in idle. It should be acurate enough (within 30 seoncds out of 19 minutes). If you use event in your VI, then simply wire 19 minutes to the Time Out input of the event structure. The VI only executes when either some monitored events happened or timed out. In your case, when it times out, just exit the loop. -Joe
Re: Modifying cluster values via refnum/property node freezes VI on quit
It might worth to try to close the reference after each loop. Creating a reference is an expensive (CPU cycles) operation. If the reference is closed, labview will close them when closing the VI, so, the longer it runs, the longer it takes to clean the memory. -Joe

Re: custamizing controls
First of all, you need to right click on the control you want to customize and select Advanced - Customize from the popup menu, this brings up a frontpanel from which you can import picutres into the control (Edit - Import Picture from file). Once the picture is imported, right click on the control and select Import Picture, different control has different selection, for example, if the control is a boolean type, then you need choose a state for the picture (True, False and Decal). Import more pictures for all the states. When finished, save the control so it can be used later. Search for the application note: LabVIEW Custom Controls, Indicators, and Type Definitions, for more detailed help. -Joe

Re: if no screen activity happens for a predefined time show dialog
When using events in labview, only the labview application is monitored for any sort of activity. Which means if the labview application window is not in focus there will be no effect. There is a Windows API Toolkit (written in LabView) you can use to monitor any keyboard activity (regardless what application), ther is also a Mouse VI Library which monitors any mouse movement and clicks for any application. Search these two files in the Developer Exchange at NI's site. -Joe
Re: stand alone exe errors using report generation vi's
It really depends on what version of office you are using. Some methods have different set of parameters or even different names, labview does not adjust them accordingly, even though the code might execute but it will fail during build process. You must reselect the methods manually in order to build the executable. Most time you need to build different executables for each office version. -Joe

Re: Serial communication to read single character
Rolf is right. If you want to read a single character just wire 1 to the byte count of the serial read. But I guess you meant differently. According to the code, data loss is inevitable. Scan string for tokens returns the first token, in your case, seperated by \s \t \r \n even if multiple tokens are available. -Joe
Re: Serial communication using serial compatibility VIs does not return correct bytes at Bytes at Serial Port vi
Most likely it is because the Termination Character, if it is enabled, by default it has hex value 0x10 . If this character is presented then a single serial read only returns everything before the termination character, regardless the number of bytes available at the port. You will need to put the Bytes at port and serial read in a loop. -Joe
Re: Serial port Write then Read issue
It is device dependent. It may be turned off but may not. Some devices will return the user input as part of the output, for example, cell phones. If it can be turned off, the manual should tell you.

Re: How to control the size/position of LabVIEW DLL front panel in MFC application?
One way is to pass the size and position as parameters to the DLL function, so when the DLL front panel lunches it changes the size and position. Also create another function (VI) in the DLL that accepts the size and position as parameters and adjust the window accordingly. Another possible way is to get a windows handle to the panel (WinAPI - FindWindowA) and then change the size and positions. I am not familiar with MFC so I am not exactly sure how to accomplish this. Joe
Re: Cutom Multicolumn list box or table
Another approach would be keep a fixed # of buttons. For example, if the list or table has 5 visible entries at a time, then just use 5 buttons, line them up with each entry in the list or table. When the list is scrolled up or down, you always know which entry is at the topmost entry, adjust your button actions accordingly. This way, you avoid maintaining an array of buttons and adjust the buttons positions due to list scroll. Joe
Re: Cutom Multicolumn list box or table
For the single column list, it is TopRow. For a multicolumn list, it is Top Left Visible Cell. Joe
Re: How to control the size/position of LabVIEW DLL front panel in MFC application?
Did you build the DLL from Labview yourself? If so, you just add another VI to the list. This VI accepts the Title of a front panel and top,left,right,bottom value of the front panel (VI property WindowBond). I'm not familiar with building DLLs using Labview so I really could not help you on how to build the DLL, but I believe it can be done (multiple VIs as multiple functions in a single DLL). To get the windows bonds for a vi, you need to use VI server property. Check out the examples under labview directory. There are plenty of them to demostrate how to use this feature. Joe

Re: how to add new entry, in table on button click.
When you want to preserve the existing values in a table or array, you need to use Array - Build Array. Wire the local variable of the table or array to top entry, and wire your new entry to the bottom. Depends on the dimension of the array and the postion you want to add. You might need to some array manupilations. Try out some of the array VIs to see how they work. Joe
Re: How to import .C code to Labveiw 7 ?

Re: Controlling VI or front panel size when published to a web page
If you have 10 controls and 5 indicator on your front panel. Group your controls close together, group your indicators together and move them beside the control group.

Re: excel version and Labview
For the Excel (.xls) file itself. If it is created with Excel97, then there should be no problem of opening it in any later version of Excel. Normally, when you use Excel components in your VI to create or read Excel file, you need to re-compile for each version of Excel. However, we have been successful so far to compile the VI using Excel 97 and be able to use it under Excel 2000 and XP. My guess would be if the VI is compiled with a lower version Excel, it would (or most of the time) work with later Excel version. Joe

Re: how can I allow labview to answer a call from a cellular...
The receive part I used was a cell phone and not land line one, so I do not have experience with that. If you want to do it with cell phones, then check out some GSM phones and their developer manuals (Most Nokia and Erricson phones will do just fine). However, if you are going to use cell phones, then check out the SMS (short message system) which you send a text message or email to the receipient which your system can retrieve it and do something. The cost is much cheaper because you can buy SMS devices / services. Search on the internet for SMS technology or just go to www.gsm.org . Joe

Re: Finding the generated html via www in a LAN?
This is a network setup issure and not related to labview. Please post your questions to other newsgroup. However, I'll elabrate just a little bit on this topic from my limited knowledge. Other people may have better answers than mine. Basically, the router restricts your access to the computer behind it from the internet. In order to show your computer on the internet , you need to either put it in the DMZ (de-military zone), by doing so, you expose your computer on the internet and it is very unsafe. Or, you can setup your router to allow a wan to lan access on a port where your web server is using (which can be different than port 80). Check your router manual to see how to do it. Similarly, you need to open the port 8080 for wan-to-lan access in order to use your webcam. Joe

You must contact your IT and tell them what you want exactly. They probably can work out something for you. Your application works in a lan environment because your request never went outside your lan. Joe
Re: Finding the generated html via www in a LAN?
When the labview server is running, you can go to to the menu to configure it, it should tell you what port is used. Or, Broswe in the NI's program directory, there is also a configuration file that can tell you which port it uses. For VI server port, you can check the preference setting from the Tools-Options from whithin Labview. The ports used by labview can be changed. When everything is setup and labview web server is running, you can use Http://ip:port/software.htm to access the pages. Joe
Re: Main VI stops when using control references.
Assuming you use the VI server to load the subvi dynamically, when loading the vi, the Wait to finish must be set to false, so your main loop does not wait for the subvi to finish. When the main loop is waiting for the subvi to finish, that case (loop) is halted. Joe

Re: Event structure
--2153655.1076616571558.JavaMail.quiq.tekken Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit When one of the subvi is running, the event that fires the subvi will not be finished until the subvi is stopped. To overcome this, you can dynamically load the vi using vi server (check the snapshot for this. Note the vi path need to be the path to your vi).

I have used labview to pick up a call on a cell phone. It is easy as long as you know the protocol used. I'm sure you can do it with landline phone/modem as well. Joe

Re: example labview VI with intensity graph for four inputs
Please learn to use the find example ... from the Help menu, search for colors, there is a VI called Create IntGraph Color Table.vi which you can use to generate the color table you want to use. Then you need to create a property node of the intensity graph and there is a property called colorTable. Wire the value you get from the other vi to this property. The VI basically cuts / divide the input of the intensity graph into 4 even quadrants (Q1 - Q4, see the coord in the vi). Each quadrants is a subset of the data you send to the graph, and each quadrants is a 2D array. As long as your data is 2D array then it does not matter what you wire in. The basic idea is to combine 4 small intencity graph into a big one, each small one occupies one quadrant. On the diagram everything inside the rectangle should be made into a subvi. To do so, select everything inside it, and goto Edit Create SubVI, Joe
Re: Ring Control displaying digital display when cleared on exit
When you clear the items, also set the value to '0'. -Joe
Re: priority in events
I am not sure you can control which event goes first when multiple comes in at the same time. Event should be use to handle simple tasks. Any time intensive / consuming operations should be put into a separate case, or even better a loop, you can put some checks there to skip them should a more important Event is detected. Joe
Re: Any way to tell when an image display has been updated?
Maybe a little bit off topic, but I remember there was a (set) VI(s) in the internet toolkit which help you to detech if there are any image (png or other type) updates. To synchronize the data and graph update, you can move or hide/show the graph everytime after each data update, so labview is 'forced' to update the indicator with latest data. -Joe
Re: Microsoft Report Generation Toolkit Error Running VI's
I would also suggest to mass compile the office VIs. Looking at the image I notied there are coercion dots which indicate the report references not quite match. Joe
Re: My data like +5.00824E-04 becomes 0.00 after through Extract Numbers.vi (labview 7), what is wrong?
Extract Numbers.vi simply demostrate extracting decimal numbers. It is not used to extract exponential numbers. To do this, you need use the BFract/Exp string to number.vi/B from BString String/Number conversion/B. Or Bthe Scan From String.vi/B -Joe
Re: How do I call another event from the current event in an event structure ?
You need Labview 7. 1) using dynamic event or 2) using value (signal) as an event condition. any changes to the value will signal the event -Joe
Re: Automation close (windows) does not work.
Have you test your vi over long period of time? Did you see the memory increased steadly? Or does it go to a level and then drop back to a lower level? From what I tested, it seems the memory does not increase all the time. The memory usage increased to a certain amount and then maintain that level (decrease and increase to that level again). Therefore I don't think there is a memory leak. The memory profile I did also does not indicate any memory leak. -Joe
