Create A Separate File With Different Procedures?
Jan 16, 2011
I am playing around with VB 2010, and I want to create a separate file with different procedures etc so that I can call a proceedure etc from this file I have a simple form with a single label on it, and a seperate file called filelib.vb.In the filelib.vb is a proceedure called LogicalDriveTypes
Public Function QueryLogicalDriversNames() As String()
Try
Dim Totalstring As String
Dim ds As Int32
[code]....
In my form1_load I have Label1.Text = filelib.LogicalDriveTypes and I get "reference to a non-shared memner requires object reference. How where / what do I do to access the proceedures / functions in this other file any time I need to from this form ?

I just happened to be reading through a post and stumbled upon this and was curious. As I was remiss to go off topic in someone else's post, I've dragged it out here.What we are doing here is logically incorrect. We loop thru all the records and set the sheet locked state and button image. But since the button is just one element, so effectively the image set would be that of the last record.We need to separate the two procedures and the events they take effect too.Ideally we should set the sheet locked state while loading it. (maybe the form_load event etc.). And we should set the button image when we switch the sheets (e.g. sheet change/activate events). The selection of events however depends on your requirements and wisdom.
[code]...
I noticed how the image was accessed above. My question is this, what is the differences between the above method and Image = Image.FromFile(Path) and if any, what are the advantages/disadvantages of each? This is just for knowledge purpose and is not pertaining to any particular problem.

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I want to create a stored procedure in SQL server 2005 in order to check if there a specific value in a table. As I don't know how to do this can someone give me a link or an example on how to create and store the stored procedure? Secondly I wrote this for my the above stored procedure: CREATE PROCEDURE dbo.dokimi -- Add the parameters for the stored procedure here
[Code]....
One of the things that I am not sure is that I want to check the value that the user passes throuhg my application that I am creating. In the above code this exists in the select query @txtUserName.text. Is this right? Can I use it like this or should I declare something more after the create procedure statement?

I have a windows form with a textbox bound to a data table and a PDF Viewer both in the same form. I could change the text on the textbox and the Viewer would show whatever is linked to the textbox. I am trying to create a separate form to put the viewer in but at a loss on how to link it to the textbox on the first form.

I would like my application to do something (in one form) and while form is doing that i would like to show another form to the user. Code is:
Private Sub blaa()
Dim a As New Working() 'working is another form
a.Show()
'Do some stuff
a.Close()
End Sub
But when i make new form i find it is on the same (main thread) and therefore new form also frozes. How to make new form on separate thread?

Query 1: When creating class files, the VB Book by Loffelmann & Purohit (p 172) says, put the class in a class file that has the same name as the class. However, as shown, I want to have two or more related classes in this file. Do I need a separate file for each class? That would get cumbersome!

Currently I'm creating a task that runs a hardware i/o loop for the duration of my program.i.e. it's a task that's created at the program's start and runs a loop that is only broken at the programs termination. Each loop cycle communicates via ethernet to hardware.depending on time outs each cycle takes 30-300 msec)I've noticed that if the loop runs with out any break that the program really slows down... to counter act that I placed a thread.sleep(x) in the loop

is it a bad idea to create separate parts/winforms of the same application (using the same SQL Server DB) in different executable files. For example for a School IS: A Receptionist App, A Teacher App, A Principal App and so on.

The company I work for has a VB6 project that is using an ACCESS database.The project consists of seperate modules such as Accounts Payable, Payroll, General Ledger, and Inventory.At the current time each module is a seperate project in VB6 and the EXE files are called when needed.In total there are about 1300 forms in the project.We are moving from ACCESS to Sql Server and from VB6 to VB2008.The question that I (we) have is as follows; Should we continue to keep each module seperate and call the EXE's or should we create one large project?What are the pros and cons for each way?Is there something written that explains the advantages of either?

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I need to be able to open a selected file (upon the user selecting it from his/her computer) in different browsers (CHROME, FIREFOX etc) I have downloaded the portable versions and placed and have figured out how to get them to open, but am not sure how to open the file selected in each seperate browser. is it possible to dictate the position and size of each window that opens? Because preferably I would like to be able to divide the screen up with each of the browsers selected.

I am reading a text file in which has three colums of information i.e.
00100 25690 21586
23510 25694 24856
25896 45478 52897
58745 59687 12364
I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.

So my issue is that I created program that writes a text file in several lines but I am having trouble reading those lines in separate labels on another program. I don't want them in one label but separated with one word to one label.
how can I put a counter on the time a new file is added to the program? I can't seem think of a code for it.
This is my coding so far but I feel like it's not really giving me anything

I have been trying to find out how to do this for days now, so I am finally asking how. I am newish to programming. Here is my problem.
I am trying to extract x,y,z coordinates from a text file arranged as such:
x,y,z
x,y,z
x,y,z
etc.
I need to be able to extract the x column into an array, the y into an array, and the z into an array. I learned how to pull it into a string, and how to split for every line, but i don't know how to split after each comma and separate them.

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?
