Hello I want to create a simple calculator with vb6.0 . Please send me a source code of it with using select case for operators. Thank u.

If you insist on finding the exact model number in the title of the manual it is possible your quest will be fruitless. Just take any manual for an EL-531 and you will get lucky. Besides, most calculators of the same manufacturer perform operations the same way.
Anyway, here is a screen grab to solve your problem.

What is the unlocking restriction code for a Nokia [email protected]

Hello,
I am always happy to polish the apple...before I eat it. (Just joking!)

All the applications that were preloaded on your calculators are available to download freely from http://education.ti.com Use the tab Download--> Apps and software. Then select software for the TI83/TI84 Family. While you are at the site download the TI Connect, if you do not have it already. The link follows.
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html You can also download the latest OS there. (Beware: while applications and programs are compatible with the TI83 and 84, the Operating systems are not.)

Install TI connect on your computer and run it to open the main Window.Then connect you calculator to a USB port and, in the TIConnect main window Click the TIDeviceInfo icon. Software will try to retrieve the info. If it does your calculator is ready to communicate with the computer.

If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable (USB or TIsilver cable), Select Port (USB1) and Click OK..

If you are lucky and it works, you can reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of course be connected to computer. To install an application already downloaded to your computer, drag it to the main window of TI Connect and drop it. Keep installing, the appilcations you want.

If you have problem with TIconnect, use the calc-to-calc cable to transfer the Apps from a working calculator. You should be on Receive mode [2nd][Link] --->>Receive. (When both calculators are ready hit enter.) The other calculator must be set to Send [2nd][Link][SEND][C:Apps]. A list of Apps appears. Scroll down the list. If you want to transmit un app you press [ENTER] when the arrow reaches its line. Once an app is selected , a small square appears on the left. After the selection, Hit transmit. I suggest you transfer Apps, one after the other. Avoid selecting them all and send them all at one go.

If you want to transfer the OS of a working calculator the sending calculator must be on [2nd][Link][SEND][SendOS]. TI83Plus OS is not compatible with TI84Plus nor TI84PLUS Silver edition OS.

In addition to the preloaded applications, you can also transfer programs the same way. For a repository of TI83PLUS/TI84PLUS and TI84+ SE, go to www.ticalc.org (or com), visit the archive section of the site.

Hope it helps.

Hello,
I cannot understand what happened to your calculator but ther is a way to restore it to health.
The operating system OS and all the applications that were preloaded in your calculator are available to download freely from http://education.ti.com.


Use the tab Download--> Apps and software. Then select the OS for your calculator TI84 PLUS and save on your computer. While you are at the site download the TIConnect, if you do not have it already. The link follows.
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html

Install TI connect on your computer and run it to open the main window.Then connectyou calculator to a USB port and, in the TIConnect main window Clickthe TIDeviceInfo icon. Software will try to retrieve the info. If itdoes your calculator is ready to communicate with the computer.

Ifit tells you Device Not found , Click communication settings in samepop up window where it said Not found, and Select Device, Select Cable(USB or TIsilver cable), Select Port (USB1) and Click OK..

Ifyou are lucky and it works, you can reinstall the OS. You drag and drop the OS on theTIconnect main window. Calculator must of course be connected to computer and trurned ON.
Now that your OS is installed you can go back to education.ti.com and download all the applications you want. Drag and drop an application onto the main window of TIConnect to install it.
If you have problem with TIconnect, usethe calc-to-calc cable to transfer the OS and any application from a working calculator.You should be on Receive mode [2nd][Link] --->>Receive. (Whenboth calculators are ready hit enter.) The other calculator, youguessed exactly right, must be on Send [2nd][Link][SEND][Send OS]

Hope it helps

Hello,
pgrm:
Loop
Create a few registers
ClrSC
Prompt : enter a or a letter to exit
Read string1
If string1 NOT numeric exit
Move a to reg1
Prompt: enter b or a letter to exit
Read string2
If string2 NOT a number exit
Move b to reg2
Prompt : enter operation sign
Read opsign
If
opsign(0) Display a opsign b
else if
print:
I have not been programmed to carry out illegal operations. Try gain
end if
pool (end loop)
end

Can you implement that in the language of your choice.

Dear here is the link that contains a sample code to your problem.

Best regard

i want to create a simple calculator using (0-9. add, subtract, multiply, divition, dot, equals ) this keys can u tell me which code i use to create this type of calculator.

i want the source code for simple calculater in asp.net

That seems fine.

I cant assume your level of confidence in programming, however, following are some simple steps you can follow to achieve (for complex implementations, much more time and details will be needed, i can help u with them as well)

1. Create a database in Access ( i assume u r using Access 2003)
2. Create a System DSN (if aren't clear, how to create then goto administrative tools under control panel and you'll find Data Sources (ODBC), here u need to create System level DSN for Access driver (may be Jet 4.0+)
3. In java, you need to import java core libraries for sql (javax.sql package specially)
4. you are almost done, just google for database code in java, simple code will be around 5-10 lines (just for your reference, search with these keywords, ClassName(""), jdbc:odbc:YourDSN)
5. Open a connection using Connection object
6. Fetch the records (select query) using Recordset object
7. You're done.

thanks

Hi Raul from your description it is very unclear what you are trying to do. First we need to know what information is on the first form, second unless you are trying to do a subtotal of all orders in the subform there is no real need for you to create a subform. Now if you are trying to create a subtotal form for all records, you will have to set it up in the record source of that subform with group by: 1. Right click on an empty space on the subform 2. Click on properties 3. Choose your table(or query) which is the record source of the main form. 4. Select Payment and items(or what ever you are trying to calculate). 5. Press the group by button 6. In totals instead of group by choose sum. 7. Exit and save 8. Now when you will select the control source you will see "sumofpayment" etc... just select them for each textbox. 9. To create the third text box you will have to use the Expression builder and just do [textbox1]-[textbox2] * for some reason the nz function does not work in this case. I hope that helped you I will be able to give you a better answer if you give me more details... Let me know what happend Good luck Daniel
