Is there any advantage to using the VB2010 express version versus the VB2008 express version? Can they be installed side by side or will VB2010 express replace VB2008? I have no issues with the 2008 version, so I don't know if installing the 2010 version would be of any advantage.

View 2 Replieswrote a program which works perfectly fine on the Win7 64 bit machine I wrote it on. Tried to run it over server and previous versions of windows (all 32 bit) and got an error (see screenshot attached) In some googling looked like there was an export function I missed so I've done: -Tools -> Options -> Projects and Solutions -> Check "Show Advanced Build Configurations" box -Project -> project properties -> Compile -> Advanced Compile -> and I've read there is something that should be changed here (the target framework?)

I created a windows form in VB 2010 and I am trying to view it in 2008, but I get the error message "The selected file is a solution file, but was created by a newer version of this application and cannot be opened".
Is there anyway I can re-save the 2010 project(similar to Microsoft word) in order to be able to open in older version?
How to convert VB2010 Express proj to VB2008
View 6 Replies(pardon me for re-using someone else's wording - but it seems this question comes up in each NEW version of the IDE) Does anyone know how to disable VB autosave? I like to open a working solution/project, mess around with it, and if I cant get it working, I like to exit without saving so that the original working version is left.
But silly VB 2010 autosaves changes, therefore stuffing up, a once working solution/project. I can understand autosaving whilst working though a large solution, but I prefer to click save once I have accomplished a routine, in the solution/project.

I use windows Vista.I had been working intensly on a new program all day today and pretty much all day yesterday. I was almost finished.Then my computer crashed. I rebooted.When I came back into Visual Basic 2010 express, I expected that somewhere I would see my files. Besides... I HAD BEEN SAVING THE FILES ALL DAY LONG USING CONTROL+S on my keyboard. The little * symbol at the top of each file would go away. I assumed that meant it was actually saving my work as I went along. I did not, however, actually go to file->SAVE at any point along the way.
After coming back into VB2010 express, no autorecover dialog appeared. I looked for my project in the list, and it wasn't there. I looked at "recent files" and "recent projects" and found nothing. Finally I searched my whole hard drive for my project, and found only one EMPTY directory located at:
C:UsersDellLaptopDocumentsVisual Studio 2010Backup Files, which matched the name of my project I had spent the last two days working on.

hook up the edmx generated classes such that we can include them on the uml models? This would be great if we could because when we do support we could reverse engineer the database, generate the objects and then directly use them in our sequence diagrams and in our workflow services. Also if we could generate code, and or link code back to the model from the UML model classes that would be great as this would let us graphically show our applications at any point.

Normally I would not bother with this, but the text files are > 10,000 lines long, which is noticable even on a fast machine. The number of lines is variable, so I would assume that one would not use a fixed value to calculate when the progress bar goes 100%.

How do i open an VBS project in Visual Basic Express Edition?
View 1 RepliesI have both the VB and C# versions of Visual Studio 2008 Express. When I run a console application in either version, instead of the console opening in an old DOS style command window like it does in VS 2005, it actually blacks out both monitors attached to my computer and treats the entire screen real estate as the console.Anyone know how to get the app to run in a small command-type window when I run it? It's like the console is running Full Screen. If I set a break point, switch from the IDE t the console and then hit Alt+Enter it switches to the small window that I want, but I still can't figure out how to make the app start with the console that way.I could post a screenshot but it would look like a big black square...no window, no frame, just the inky blackness of frustration.
