im slightly new to VB, i was wondering how I make the program check a file for an update, i kknow there is an option in the app settings, but when I go on it it doesnt recognize .vb or .exe files to check from.
If i uploaded updates to a server, how would It check that for updates? and what file type would i need to upload it as?
I create a project using query sql ( Select, Update,Delete,Insert ) in many various way. example by Select with condition ..etc someone work in programing field. tell me that you are not profession in using vb.net , because you have to use OOP instead all of these Sql query. because if you want to make any update on your program after start to work on the Pc you will open your project on design and change the code. but in OOP you will make update on class and then put it as DLL file in the file of program.

View 1 RepliesSupposedly I create a file called "hi.txt" and I use Process.Start(filename) to open it. then I File.Opentext(filename), edit it and close it using stream writer/reader, while I still have that file open.
In order to see the changed text I need to close "hi.txt" and reopen it.
Is there a way to automatically do that? Been experimenting a bit but with no luck.

View 2 RepliesMy boss has just asked me to make an "Update Program Function" for our program.My program is being used by someone in my company. The database is put on server computer.At the present, my program run by some dll file, and when I fix or update the source code, i will compile to dll and put it on the server disk. After that, the users will go to this server disk and copy the new dll and overwrite the old dll in their client computer.
Now my boss asked me to make an "Update Program Function" : before the user login, the program will check the version (or the creation date) of the dll in the server disk, if it newer than the current dll, the program will update the new dll, else the program login normally How can i do that?

View 1 RepliesI am trying to make a vb.net program which will perform WMI queries to check for remote computer's name and OS. I manage to do the first query of name using the code below..
[Code]...
I am getting error "Local variable 'query' is already declared in the current block. (BC30288)".I understand that I am using same name for the object variable for performing subsequent query. Is there a way in which I can dispose the variable completely and reuse it again for querying the new required WMI detail? My search in the net couldn't give me any clue as of how to clear the variable and use it again. The issue is with two variables "query" and "searcher". Is it only possible that I should give unique names to each query object variable as I might add more queries later on?

View 9 RepliesI have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.

I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields
