Have a bit of code ported from VB6 to VB.NET. It uses Write and WriteLine all the way to produce output files.
Now, I need to compare outputs from original and ported code, but there's one tiny problem with number formatting. For instance whereas VB6 code Writes just .5, the VB.NET code produces 0.5, instead of .0005 (in original) it writes 5E-4, etc.
How can I make VB.NET's Write to write numbers in the same format as VB6? The option of refactoring writing code to include formatting step is not acceptable.

I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

Am I on the right track? I am getting an output to a text file but its just one line ans always says PASS.
I'm trying to adapt a VBscript that runs the QWINSTA command against a text file I've defined as an array and displays the results in a text file.after looking at numerous examples on Stack and other sites this is my latest iteration, that displays everything except the STDOUT, which is really what I'm after, not sure if it's an issue with how I'm calling the command piping the output or what. I'm also passing two variables as arguments to complicate matters :)
The Text file that stdout is piped to is empty after the FOR Loop completes I may be going the long way about this, most of my past experience with this is in BATCH

View 2 RepliesI am using Visual Studio 2010 Professional in trial mode... and suddenly the Output window won't show my Debug.Write() stuff. It had been showing it for the past month.I have been using the 2010 version for 30 days (after upgrading from Visual Studio 2003) in trial mode. I just renewed the trial for the extra 60 days, and the "About Visual Studio" window says I still have 59 days left.
I have verified that the application is running properly, without errors. When I purposely generate an error, the Output Window properly shows the error and the stack trace I've already checked my Build>Configuration... it's in "Debug" mode, not "Release". The Debug.Write() text is not going to the Immediate window, either.One other point, I tried running the same application in the Visual Studio 2010 Express Edition, and it complained that it could not debug the specified code, though it did properly build it so that it would run in the build. Could Visual Studio 2010 Express have modified something in my project files to disable the debugging output?

I have a datalogger with his own program on Windows via a RS232 port. This datalogger records data in two ways :
1- continuously (see picture 1)
2- when pressing 'Start recording' button.
The datalogger record a value each 1 sec. Between 2 values, I need to move a stepper motor. I want to synchronize the stepper motor with the datalogger. So, right after the data is recorded, I move the motor and I wait for the second data to be recorded, etc. The problem is the synchronisation. I have access to 2 triggering method when the data is recorded :
1-when a row is added in the grid (picture 1)
2-when the 'Recording' value change (from 5 to 6 by example)(picture 2)
The easiest option would be the second one because the 'Recording' value isn't a textbox, it's included in the general form. I cannot access to it directly. The class of the datagrid is Thundergrid and his name (Caption) is LIST. I want a VB program that will do the following..When I press a button in My Form :
-Get the handle of Thundergrid class, LIST named.
-Wait until the datagrid row number is 10.
-Then, a variable n will count +1 at each added row in the datagrid.
-Each time the n value will change (datagrid add a row), the motor will move.
-When the n value = 121, the cycle is done and I can collect the data.
For the interaction with the motor, it will be done by grounding a pin in the parallel port.I do not need help with the motor control, only the n value need to be synchronized with the datagrid.Please refer to the attached pics. I used Winspector to get the class of the datagrid. It is in the red box.
