I have been developing windows and web application using Visual Basic 2005 for a long time. Now i want to change from Visual Basic 2005 to Visual Basic 2008. I would like to know what ever projects i have done in visual basic 2005 will works in Visual Basic 2008. Will the existing code in visual basic 2005 supports Visual Basic 2008 or do i need lot of modification. I haven't used VB 2008 but i hear that most of the code which written in visual basic 2005 supports visual basic 2008. What are the things i need to take care when working the existing projects in visual basic 2008.

View 4 RepliesI'm attempting to use waveOutSetVolume from coredll.dll to gradually increase the audio volume from silent (or near silent) to maximum.
Most of the code examples I'm finding show some predefined set points for Off, Low, Normal, Medium, High, and Very High like this:
Public Enum Volumes As Integer
OFF = 0
LOW = 858993459
[Code]....
OK, and here's some API documentation which doesn't make a lot of sense to me in this particular context. What is low-order word and high-order word and how can they both exist in a single value?
· dwVolume New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence. If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.

Would run on windows mobile 6 I would like to have both these versions store and read data from a database that can be stored centrally either on a webserver or somewhere on the LAN.
I would like to know can i use Access as my backend database or sql server ? will windows mobile app be able to access it and read and write to it Note : I would prefer to create only one database that will just store the details in the tables and do not need any other functionality. All functions such as save,edit,delete,search,filter etc with be done from the FRONT-END VB.NET interface ONLY If you suggestion involves the use of 2 databases such as one for desktop version and one for windows mobile then please also tell me how would i sync the data between them.
one of the apps that I wrote a couple months ago is getting to be rolled out to my production floor; one issue tho - It works great as a standard executable (you double-click, it starts and waits for data), however, I cannot get it to start as a system service.
I've already done a little bit of research for how to create a system service, but most of the information that I've come across is point to VC# or Visual Studio 2010 - I'm not finding much for VB 2010. Additionally, I'm only using VB 2010 Express and I'm pretty sure that I don't have the Windows Service application template's on my PC.
My application does have a "UI", but there isn't any user interaction; it starts and just sits minimized in the system tray polling a directory for the existence of a file - i.e. the windows form is not required.

I have a vb.net application that uses ShowDialog() to open child screens.
Long story short, I had issues with focusing the control if I opened IE on top of my program without minimizing the program. Once I reactivated my program and closed a child window, IE would show again instead of my program. I fixed this by setting the owner of my form.
Now I have another issue. After setting the owner, the parent (text) name of my form is now being shown at the top of the application when a child screen is open instead of the parent name. How can I fix this to show only the child's text form name when a child screen is open?

I have 5 different applications that I have written for my business, they are all interfaces for a point of sale system. I TCP/IP interface handling part of the application is rock solid, problem is that occationally I will come across a small issue, such as a memory leak that I came across a few weeks ago. After I fixed it, I had to then fix said leak in 5 different projects as they all use the same interface base code.Now, if things were different, say a function that all my applications used I would just write it into a class in a dll and have all my applications use the function from that class. Problem is however, using a parent/child explanation unlike my example here where I have interface 1 - 5 as my parents using common.dll as a common child. I need to have InterfaceParent using 5 different children with different attributes.That being said, there are a few stipulations, depending on the customer I may only need to install interface 1 and 3, or 2 and 5, or 1,3 and 4.
View 2 RepliesI have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

i Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using

General is a form but also a class, so I wonder what it the pros or cons of using :
System.Windows.Forms.Application.Run(General)
vs
Dim gen as general
System.Windows.Forms.Application.Run(gen)
In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable.
