I write text to a file using StreamWriter as shown below several times a second. The problem I have is that sometimes these files are left blank after my program has crashed or the computer has crashed. I've done several searches on the internet without any results other then writing to a second file, copying over the file and then deleting the extra file when done. If this method doesn't have any error modes it still appears to be less then a beautiful solution. (What happens if the computer crashes when writing over the original file?)Is there a more secure method for writing the text file that doesn't leave it vulnerable? This happens way too often. I never find errors related to file writing. I really want this code to be reliable enough that I could just pull the plug on the computer
Try
Dim mSW As IO.StreamWriter = New IO.StreamWriter(countFile, False)
mSW.WriteLine(CStr(totalCount))

If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I gotta finish this application. When the "Enter Numbers" button is clicked, the application displays an input box for the user to insert an integer. After the number has been typed and the OK button is clicked, the application is supposed to give out the sum of all integers from 1 to the value entered by the user. Example: If the value entered is 5, the sum will be 15; if it's 10 it'll be 55 This is my code but something's obviously wrong, it is maybe in the loop?

The result I get for 5 is 25, and for 10 is 100!Also, could you tell me how to display the result in a message box?

I'm making a custom control that needs to look like a Text Box but I can't Inherit Directly from text box since I need to add, Change and Override so many things that it would be more practical to just inherit Control and start new.
But now my question is: Is there an easy way to create the basic functionality of a Text Box like drawing the Text Box and handling input ?

I am trying to get the enter key to invoke an action from in a textbox. I want it to click a button. In Visual Studio 10, which I am using, the is an "Events" selection in theproperties area. Under this there is an "Enter" which allows you to pick something to invoke. So I choose the button that I wish to invoke. However, when this is selected this way, I run the debug and after i type something and hit enter in the text box, nothing happens and I hear a default sound. Why is this not working as it appears it should? What am I not doing right?

This used be an issue in VB6, I'm wondering is it better in vb.net 2005. Users like to hit [Enter] (or tab) to navigate from text box to text box. Now I know I can write code to trap the pressing of [Enter] on each text box key press event, but surely theres a better way?

Basically, I want to have a text box that will display text associated with the text input.
For Example:
input : 512
output : TEXAS
or
input : 659
output : ALABAMA
I have heard that it is possible to do this, and I would like to find out a way to. Even if I need a separate text file with the arrays, I would like to get this to work.

At the moment I have created an AutoTyper but can not get it to function in the way I want it to. I want it to have the option of choosing whether or not the enter button is pressed after the text is sent. Currently by changing True to False I can make it either send the text or send the text and hit enter. However I can not make it so it has the ability to do both.
Here is the code I am using:
Dim CheckBox1 As Boolean
If CheckBox1 = True Then
SendKeys.Send(TextBox1.Text)
SendKeys.Send("{Enter}")
Else
SendKeys.Send(TextBox1.Text)
End IF

ok I've read tons and coded tons and I'm just not sure what I'm doing wrong.. I have to assume its because there are 900 ways to do sendmessage with the windows API and I'm just not doing the correct one..
I made an an app that runs up and shows me its window handles.. my other app can find the one textbox and return the handle.. now I just have no clue how to send the message correct to make my string pop up. Do I need just the handle ? or do I need to get the handle of the text property using the getdlgitem ??
