Pausing An Application Until A File With A Certain Extension Has Been Created?
Oct 21, 2009
I would like some information on pausing my application until a file with a certain extension has been created. What hapens is, my application creates an input file that is sent to an external app that returns a file with a different file extension. In my application i then extract data from this new file.I was thinking i could use a timer to "hold up" my app, but then i started reading about event handlers and catchers. What i have tried is using an If FileExists loop but i get a file not found exception. How should i use the file create event? By looking in the folder and "waiting" for the file to be created?
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.

I am writing a very basic memory match card game, and am trying to get the program to flip over the selected cards, wait 2 seconds so the user can see the values, then flip back over. The code I have to do this is:
Private Sub Label_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, Label6.Click, Label7.Click, Label8.Click, Label9.Click, Label10.Click, Label11.Click, Label12.Click, Label13.Click, Label14.Click, Label15.Click, Label16.Click Dim message As String = "Label Clicked was Index" + sender.TabIndex.ToString
I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?
I'm looking for a way to pause my application while in a loop without affecting the users ability to control the application, the sleep thread method makes it seem that the app is frozen.

Is there a way to play a wav file and then pause for 10 seconds and then it will repeat? I know it will be a loop, but the part that gets me is pausing for 10 seconds before starting the loop again.

I implemented a Module using VB.NET in order to handle localization in an MVC .NET application.However, when I try to call the extension method LanguageSelectorLink from my view, it`s required to provide something for the first parameter of type HtmlHelper.

I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "") Dim source() As Byte = System.IO.File.ReadAllBytes(filePath) Dim compressed() As Byte = ConvertToByteArray(source) System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents Dim streamObj As Stream = New StreamReader(FileName).BaseStream
[CODE]...
I need to compress the file without loosing file extension inside compressed file.

[Code]....
How can I modify that function to return the file regardless of whether the extension is in caps or small letters?

Recursive File Copy based on file extension. I have a single root folder that contains numerous folders that contain a few files that I want to extract. For this example, lets state that I want to copy all �txt� extensions and put them into a repository folder.
Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
