I am using this:
Dim oFile As System.IO.File
Dim oWrite As System.IO.StreamWriter
oWrite = oFile.CreateText("e: est.txt")
oWrite.WriteLine("TEST")
oWrite.Close()
Which works, but I would like to have it so instead of creating test.txt it names the document using multiple input text instance.
I have a little banking console app for a class project. I've created a class (Account). What I want to do is name the instance of the class based on text input:
Dim strFoo As String
strFoo = Console.Readline
Dim strFoo as New Account
Obviously this won't work because strFoo is a String.
I know how to add a single node to a top level node in an XML document, but I cant figure out how to add multiple (nested) nodes to another node. For example, I want to add this node structure to node called "PaymentInformation":
<Prepaid>
<BillShipper>
<AccountNumber></AccountNumber>
</BillShipper>
</Prepaid>
Do I have to add each node separately or can I add them all at once?

View 1 RepliesIs there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.

View 2 RepliesWhat I am doing is creating a simple login and register system. I am going to save the information of each user into a text or ".dat" format and have them placed into a folder called "accounts".The small problem that I have is the "Forgot Password" option. I can't think of how to search all the documents for the e-mail or the username.So basically I need to know if it is possible to do a small search for the e-mail through all the documents in the "accounts" folder.
-I know another option may be databases...but I don't completely know how to use these.
-I have general knowledge of arrays

View 7 RepliesI'm having some difficulties chopping up a word document. I think the problem may be that it's 900+ pages, but I'm not completely sure.The separate documents within the document file are separated by x of 100 documents. I'm trying to split at the "of 100 documents", however when I try to split the string that I put this word document's contents into, it will only split with the first letter I give. So, when I try to split it by "of 100 documents", it will only split by "o".

I'm creating an application that allows the user to create their own queries based on criteria in various list boxes and my idea was to produce the results of the SQL in a "new" DGV, which in turn will be created in a "new" TabPage in a separate form . Each time the user runs a query a new DGV and TabPage is created. I've named each "new" DGV based on a user textbox so each "new" DGV will be named differently. The problem is how do I reference each new DGV? At the moment I get-"the value of type 'Syst.cannot be converted to string"It allows me to name the DGV with a string, but not reference it!
Any ideas how I reference a DGV when its created in runtime.

View 11 Repliesim writing a program for counting the cash in a till.i have most of it worked out through research on this site and others. im trying to code a text box that allows the user to enter any amount between 0 and 9999.99. I have everything working except restricting user from entering more than 2 digits after the decimal. I could leave it as is and the currency format that im using will automatically round the input to 2 decimal places but this creates a problem if the user accidentally enters an extra digit and the program rounds up. for example if the user intends to enter "23.34" but accidentally enters "23.345" the program will round up to "$23.35" which will cause a problem in the end calculations.here is the code. if someone could explain what i need and where that would be great.

Everything else is working great except for the writing/reading part of it. I had put this together originally without the intention of bandwidth monitoring, but I've decided it would be a good thing to have.I want to have 2 monitoring types: Windows Session Bandwidth Total & All-Time Bandwidth Total (since the program was 1st run on the machine). The counter is on a Timer (2nd of 2), and I want it to write and add the label values each second into the file, then when Form3 is opened, to read the text file and show the results.

View 2 RepliesI am in the process of trying to build an app that will permit multiple instances of the same form be added to an mdiparent as seperate mdichildren. The reason for this is that the child's data is based on a sql table's row information. Thus child one shows requested data from row 1, child two shows requested data from row 3 etc.
I have this setup so that each child is its own seperate tab in a tabcontrol. My problem is that after the second instance of the child is created the form in the first tab is disappearing after the line:
child.midparent = me
I don't understand what is causing this.
Dim child As Form = Support
Dim tab1 As New TabPage
