View 19 RepliesI have an application that plays wav and mp3 files using the Microsoft.DirectX.AudioVideoPlayback.Audio()function. It works fine, and I can easily set the volume level of the playback... within limits.
That limit is the system volume level. I can set the playback level for the mp3, but if the system volume is muted or set real low it may still play softly.
So how do I set the master volume level, including making sure it isn't muted?
i don't want to use the system date and time in my mini project.i want to create my own system date and time to be in sync with standard time i specify?
View 3 RepliesHow do one create System Level environmental variables manually. I just installed a GeoSupport Desktop Edition software and in the document it is mentioned that I need to create system-level environmental
variables for PATH and GEOFILES manually
Add the location of the GDE executables to the system-level environmental variable PATH.Normally this means adding C:Program FilesGeosupport Desktop Editionin to the PATH.
I have searched the web for code relating to changing the system volume, muting the system volume, and outputing the current level of the volume as an integer, using VB.NET.
All the code that I have found either doesn't work, or is very long.

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.
View 14 RepliesI have a custom developed control I am using that somebody else wrote. For some reason, when the control was written, they did not write an event handler for the "mouseDown" event so when I mouseDown on the control, no event is fired. What I am basically trying to do is capture which mouse button (left or right) is pressed when the control is clicked on. Is there any sort of system level objects that maintain system state (including which mouse buttons are currently being pressed regardless of the control being clicked upon?)
View 1 RepliesI have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.

Hi Friends,
Hope you all are doing fine.
Brief
I have been into learning VB 2010 Express for around 2 months now; I have been doing it primarily on weekends with a nice book by James Foxall. At the moment I am in Chapter 22 of 24. I have been able to make some sense on what he says but have
been able to follow him well. I plann to read the book in full twice before doing with it at the end of August 2011.
Today's Question
In one of my previous threads 'Becoming a Programmer' @Renee Culver encourages me to try to get to a level deeper. There are many other experienced programmers who have given adivce with equal 'punch' but I like to begin with @Renee Culver's
approach.
James Foxall guides me learning smoothly but I now at the 22nd chapter out of 24 feel a little uneasy. It feels like James tells I do. In Chapter 22 dealing with automation he guides me to work on Excel through VB. The reference to the Server is
set through the VB interface. I like to know how to get to a level deeper on this today. Instead of using the VB interface can't I establish reference purely through VB code? During this weekend I like to try accessing the Google start page
Combo to get search results for 'Novak Djokovic'. Could you help me?
Thank you Friends.

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.

View 13 RepliesI was just wondering why there isn't a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are being executed in an application. This feature is a part of log4J. I know I can create a custom level like is talked about here but I don't want to put time and effort in something I feel should be part of the library itself. Do you know about a log4net extension library which implements this or why this wasn't a part of the port to .net ?
