I understand the concerns. What I have is a huge list of if statements associated with one of my buttons. They all will return this date in some way. Instead of having a million copies of the same code, I want to reference that class so when I change something within that class, it applies to all instances of the code.
The error I am getting is An object reference is require for non-static field, method, or property.
In each and every if statement seems like it would be a big waste of code and space. I have about 20 buttons or so that would use it, each with 2 if statements attached. I want to just reference that code in a helper class and just have to type something like this:
Sorry Dave, didn't realize you had already prevented that from becoming a problem. I just added another private const string to display hours and minutes how I desired, and it works flawlessly, you sir, are a gentleman and a scholar
i have 2 RFID readers that read active RFID tags ID within range, and i have written the code in c# and it works and reads the tags. each tag represents a device.
i have created a database on MS access provides information related to each tag, such as serial number, location, company,...
ISSUE: i need to insert the tag ID to the database and only update Location coloumn, AOTUMATICALLY. as long as the reader reads the tag the program has to update the location where the rest information will be as they are.
i have 2 readers (reader A & reader B) so that i have to compare the data coming from each reader in order to update the location. if reader A reads the tag ID and reader B doesn't >> location updated to Location A. while if reader B reads the tag ID and reader A doesn't >> location updated to Location B. and if neither of 2 readers read the tag the location will be (OUTBOARD). also if the readers read the tag ID at the same time ( readers range interfere), the location will be (mutual A&B).
readers are real time working, and i need to do the updating aotumatecally & continuously.
1. Create (learn) how to do database insert and update. This does NOT have anything to do with the reader data. It is just basic knowledge.
2. Use 1 to create an API that creates/updates RFID data. This has NOTHING to do with getting the data.
3. Write code to read from a SINGLE reader and then call the API in 2.
4. Create (learn) two threads. Each thread calls 3. Maybe with a delay or maybe not. Depends on how you tell if the reader has data or not.
first of all, thank u for ur reply.
1- somebody told me that there is library codes already created to do this purpose, is that true? and where can i find them?
2- i'm not a programmer, unfortunately, so that i really need more explanation.
3- if u don't mind we could communicate on skype or teamviwer,..etc, to discuss these steps.
4- if u mind, can u provide me the best and easiedt references on tutorials?
5- if u know someone is ready to solve my problem and programs it i'll be really thankful.
and i have written the code in c# and it works and reads the tags. each tag
represents a device.
This statement would seem to be at odds with your other post that says you are not a programmer.
I really need help ASAP.
Per your other comment that you want to hire someone.
You might want to look to a employment agency and an employment lawyer. Both should have experience with software.
The first provides candidates. The second insures that what you get is what you paid for.
1. You should improve your requirements.
2. Make sure that the lawyer knows that you want to retain ownership of the code.
3. Make sure that the lawyer knows that you want to insure the product works. To that end your requirements will need to state HOW you would determine that.
4. Make sure that hte lawyer knows that will want to provide bug fixes to the code. Or not if you want to try to do it yourself.
Then you just need to find a candidate you like, get them to sign a contract (the lawyer approved one) and then get out your check book.
You probably should pick a local candidate because then you can sue them if they fail to deliver (breach of contract.) Doing that is generally easier if it is local although there are some localities where it is better for you (contractor) than for the (contractee) which is something else you should ask the lawyer.
