VS 2010 IO - Check Location Of File And Create New
May 26, 2012
Is it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If

Using: Visual Studio 2005.We are developing three different applications. We currently have 4 different modules that we all share among our applications. When a change is made to one of the modules, we must make changes to the other two modules.If it is possible, how do you (where do you) create a single location for one file to be shared among three different applications? Hopefully this will avoid the unnecessay task of changing a file three times.

Im trying to make a program that works a bit like the log in on a computer. But i cant make it load a different .config file depending on what username is used. I want it to load a config file from different directories that match the username. eg if the username was bob then it could be: C:MyProgramLoginBobapp.config I've been teaching myself and this has had me stuck for ages.

Ill be using .ini files eventually (just testing with txt files to check it was a valid aproach) I can get all the info i need into the txt file, the problem is how to read it back into the app?

1. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done
2. Basically what I want is during my Splash screen which runs for 5 seconds I want to check if a network drive is mapped.
if not, pause splash screen ask user for address of drive, map drive then un-pause splash screen and continue with load how do I check if a network drive is mapped? and how do I pause the splash screen?

I'm making a program in which a couple of txt files will be used for reading and writing (streamreader/writer). Incidentally, these txt files might be in use by another program, although never more than 1 or 2 seconds each time.
Suppose, I have the following
Dim Input As New System.IO.StreamReader("c:data.txt")
Data = Input.ReadLine
...more code...
[Code].....
This doesn't work though. When I open c:data.txt in another process and run my VB application, I still get the IOException.

Its been requested that my project has a way to limit number of users logged in at one time. I have that figured out but there is a problem. What I have done is that when a user logins in the application creates a .usr file in a directory on the network. If the number of users (value in the database) is less than the number of .usr files another user can log in, otherwise they can not(the file gets deleted at logout or application close). Now the problem is I need to create a way that if the .usr file get deleted the application will close. Is there a way to keep a watch on file and if it gets removed close the application.

Dim Process2() As Process = System.Diagnostics.Process.GetProcessesByName("word")
For Each p As Process In Process
If p.MainWindowTitle.Contains("test") Then

I need a check that will see the location of the edge of the form. An example would be (for what I am trying to do) is, when a form is moved, the main form will get bigger depending which border and which way the second form is going.So basically I need some way to make Form1 get bigger if Form2 is near the left border or near the bottom border.
*I have a mini system for making it grow(LocationChanged) on the form I want it to work for.
*I also know about ".left" and ".top",

I have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

I have am Explorer form and I want to be able to use a treeviewNode and all of its contents to create a windows folder structure.Each Treeviewnodes would be used to create a folder.
The problem I have is that I am using a SaveFileDialog Form to allow the user to specify where the Folder structure should be created and it only accepts a file as input or end point.
How can I get the SaveFileDialog form to accept a folder, e.g the desktop, without specifying a document in the folder?

My requirement is to create a XML file based on an XSD. The source data for this file will be coming from a database. For the purposes of this test, I am trying to manually assign the values.
I followed these steps:
1) Used the XSD.exe to create a VB Class.
PHP
xsd /d /l:VB emprec.xsd /n:XSDSchema.EmpCollection
2) Added the VB Class in my project.
3) If I try to compile my code, I get an error.
Here's the code I wrote:
VB.NET
Private Sub cmdXML_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdXML.Click
Dim emp As New EMPLOYEE_COLLECTION
[Code].....
How do I resolve this? I am unable to add any code in the 'TODO section for this generated class.
