Can someone help me in learning how to make business cards using pages

can someone please help me in learning how to make business cards using pages

You could jump start the process with an Avery MS Word 8-up business card template as a free download. Either version of Pages will digest it nicely. Once you load it into Pages, do a File > Save As Template.. , add it to Chooser, and give it your name choice. Both versions of Pages will remove the printer registration marks in all four template corners. The free LibreOffice Writer retains them.

How to make a driver using DLL in LabVIEW?

I had followed the "Using Exteranal Code in LabVIEW" manual having finished the making dll file, and the lsb file(I attempted that two ways). But when I load the code in LabVIEW, it can't work. I don't know what had happened, I only got a error message like this:"'0x100014f1'commond call memory'0x00000000',this memory can't be written" or other similar error message, if I push the "enter" button, the vi application which I having lunched will crash. If I push the "cancel" button, the debug model will start,and the next message is "Unhandle exception in LabVIEW.exe(MSVCRTD.DLL/LVS95.TMP/COUNTER.DLL(the last one is creat by myself)):0xC0000005:Access Violation", but I wonder what had cause this? My DLL had been made successf

1. Can you call this DLL from within VC?
2. What operation system do you use? There may be a problem with calling of win95 dll under NT or win2000 for example.
3. If you use NT you may not have permissions to work with some ports and memory areas.
4. Under NT or win200 try to compile the library as a 32-bit dll, and under win95 - as 16-bit one.
Good luck.

Re: how to make bode plots in Labview 7.1 without using Control Toolbox

I am using Labview 10. I have connected a signal generator, a LP RC filter and an oscilloscope. I am using Labview in order to control the generator (sine with frequency sweep) and acquire the signal from the scope. I want to plot the Bode diagram without using the transfer function, from the amplitude of the sine signal and the frequency.
Thank you very much.
Best Regards.

Hi pflo,
Are you using the CD Bode Plot VI or the SI Bode Plot VI? For the CD plot you must use a transfer function. Below, please find a link to an example on how to create a Bode plot without using the toolkit.

How to make bode plots in Labview 7.1 without using Control Toolbox

I'm trying to make a bode plots from transfer function using Labview 7.1. My installed labview not contains any toolbox, so I have to create the block diagram of bode plots my self. I have a problem when creating the phase bode plots for polinomial with conjugate roots pairs. Suppose the polinomial is ax^2+bx+c, with a,b,c is the polinomial coefficients. If b coefficients is negatif, i have no problem, because the phase is start at 0, and the final value is 180. But if the b coefficient is positive, the phase plots starts at -180 and it's final value is 0. So, if there is any one who can helps me to give any solution, i'll really appreciate that. Or if there is any of you who had made the program to create the bode plots from a transfer function, i hope you can share the code with me. Thank you.

Hey pflo,
Are you using LabVIEW 7.1? Can you explain the problem that you are having with the using the Bode Plot VI? Below please find links to some documentation on the Control Design Toolkit. With further information on your problem I will be able to better assist you with the toolkit.

How to implement wafer mapping using LabVIEW?

Hello LabVIEW Masters!
I am having an incoming project which includes controlling and gathering information from a PROBER. One of the difficulties I am having now is how to implement a WAFER MAP using LabVIEW. According to my customer requirements, the wafer element ranges from 6k to 23k. I guess doing all the element (one die = one led ctl/indicator) will be a hell of a task, especially on how to effectively manipulate each elements. Does anyone have better idea on how to this?
Please, I badly need your help..
Thanks and Regards,
Dennis DG
Solved!
Go to Solution.

Hi Dennis,
Is it okay if you send to me the working VI also?
No, it's not ok. I made that program for my customer...
As I am not too familiar in using intensity graph.
That's no reason to hand over programs for free...
My customer also request me that if the cursor hover on the wafer map, he wants the x,y corrdinates to be displayed.
I also have such a feature. Did you notice the little yellow cursor near the center of the wafer? One could easily change that to use a MouseMove event instead...
He also wants to select some elements in the wafer map and come up with the coordinate values to do some testing.
That's related to the cursor thing...
Some points:
- You have a customer that pays you. Why should I offer work for free?
- You can send me contact dates of your customer, I will make him an offer...
- When you take an job to provide software you should be able to code the software...
- The VI(s) are now some years old. I didn't code so well back those days and don't want to hand out those VIs as they are right now.
- I included some "license management" deep inside that program, I would have to remove this and spend time on testing afterwards...
- The VIs are based on the PROBER output format used by the customer. All the file handling has to be changed for/by you...

How to simulate an lcd using labview

hi
i need to simulate a graphical lcd in pc using labview?(7.1).
i have posted this earlier and got replies.but i wish to know how to create the lcd screen?
i think i can make use of booleans.but i need the exact details for creating the graphical screen.
and on how to make each pixel glow(i.e., ON and OFF)
can anyone help me out in this issue..
regards
mahi

Hello Mahi,
I just jumped into this thread and remembered, that a few years ago I had a project to generate c-sources (actually header files to be included into c sources) to show custom made characters on an lcd display. As a side effect it creates what you need, a 3D- boolean array, where every 2D- portion holds a character.
With this program you can define the size of the character and alter it the way you need it. You can import a bmp- file with characters you need (e.g from a screen copy, must be a 1-bit bmp, black&white) and copy little frames from it to make work easier. If you click in the menu at "Fonts->Save Bool Spreadsheet" a text-file will be created which is in spreadsheet-style, where every cell (if you open it in Excel) consists of 0 and 1 according to the character. If you scroll down the front panel, you will find the 3D- Bool array which represents this data.
Just try it, the top-VI is "Fonts V2.vi", it should run properly. I put some screen-copy-bmp file and *.h- files into the zip to make the test easier for you.
I hope this helps,
Dave

How to create a database using LabView?

I have to figure it out how to do this, but .... no idea. Also i have to make a search in that database. If you can help me, i apreciate that or if you know a link on the web about something like this
Thanks,
Lorant

Labview configuration files are very easy to use and can hold any type of information you wish. There are functions in the File palette ready to use for configuration files. A configuration file is similar to a registry entry. You can have sections and keys. So you can create a section called "Data1" and keys called "Name", "Age", etc. Create the same for a new section called "Data2", and so on. The functions are useful for writing the config file and reading from the file. To read a certain piece of data, just supply the section name and the key name. So you could ask for section "Data20", key "Name", and you would get the 20th name in the database (config file). This way you don't have to write code to search the database for certain items, the functions do it for you and they are already written. Look into config files. They are very easy to use, very useful, and very underused even by the most experienced LV programmer.

How to make editable Table in LabVIEW

Hi,
Could you please let me know how can I make an editable table. I read all the contents of the table from a spreadsheet file but I would like when I click on any of the entries in the first column I get checkboxs for all the entries in that row and after updating them the table should also automatically be updated with new values
For example
Let's say this is my table
Device Name Bit 0 Bit 1 Bit 2 Bit 3 Value in binary
1 1.bit0 1.bit1 1.bit2 1.bit3 0000
2 2.bit0 2.bit1 2.bit2 2.bit3 0000
3 3.bit0 3.bit1 3.bit2 3.bit3 0000
4 4.bit0 4.bit1 4.bit2 4.bit3 0000
Now if the user click on 1, I should see 4 check boxes for 1bit0 1.bit1 1.bit2 1.bit3 and as soon as the user update any of them the binary value should be updates . For example if the user enable 1.bit1 and 1.bit 3 then the binary value should become 0101
Could you please let me know if I can I use Table control to do this and how can I do it in LabVIEW
Thanks

Why does the user even need to select a row first? Wouldnt it be sufficient to have an array of clusters, where each cluster contains a devicename string, four enums with 0,1, and a string for the value (or binary formatted numeric). Elements that don't accept inputs should be disabled, but not greyed and can be recalculated whenever needed.
The main problem is the cosmetic fact that this will no longer resemble a table because of all the extra borders...
... That's why we have this idea! Go vote for it!! Thanks!
Here's what I had in mind (LabVIEW 8.2). All you need to add is parsing your input file into the cluster structure. If the number of clusters is large, show the vertical scrollbar of the array.
(...note that it would look much better with my above mentioned idea implemeneted! )

How to make an activex in Labview!

I don't know how to make an activex in Labview5.0.How can I do ,can you tell me the specified steps?please!
Thanks a lot!

If you want to embed an ActiveX object on the front panel, you go to the ActiveX palette and drop a container there. You select the object by right clicking on it and choosing "Insert ActiveX Object". You then browse for the object you want. In your diagram, you use property node and invoke node functions found on the Communication>ActiveX palette. You can also use the Automation Open function and in that case, you just use an automation RefNum. There are examples (at least LabVIEW 5.1 has them) - Help>Search Examples>Communication>ActiveX.
If, on the other hand, if you're asking how to make an ActiveX object out of a LabVIEW VI, that's not possible.

How to access parallel ports using LabVIEW?

I want to send data to a device which is connected through LPT1.when Iam using serial port write.vi with port number 10(for LPT1) it is giving an error code 37 which means the device not found. whether those vis are only for accessing serial ports? Then how to access LPT1 using LabVIEW?

Most likely you need to modify your labview ini file to let it know that LPT1 (or whichever) will be controled through the serial port control. See the following link for a knowledgebase answer to this question:
