I am trying to write data to a binary file using the Print() method, but when I run it I get the System.IO exception Bad File Mode.
Here's the code for the FileOpen declaration, that might have something to do with it?
FileOpen(filenumber, "path to file", OpenMode.Binary, OpenAccess.Write, OpenShare.LockReadWrite)
Print(filenumber, expression(variable))
Is it easier to print a VB.net windows form in Visual Studio 2010?
I have been struggling with this - the PrintForm utility in the Powerpack only prints the displayed portion of the current form.
I spent a lot of time creating a process which loops through each control on my form, converts to a bitmap, and drops it on the print document, only to finally discover that the RichTextBox control (which I used extensively) does not include a functional DrawToBitmap method.
I have already researched various ways of managing this, but if VS2010 will do it without jumping through the hoops then I'll spring for it like the sucker I am.
I can do this in Access and VB6, I believe, so I don't think this is an unreasonable expectation.
Have anyone worked on a project on 2 different computers with different version of Visual Studio Express?
In my case, I have made (and still working on..) a project in VSE2008, which I have installet at my job-computer.
At my homepc I have VSE2010 installed. I am a bit afraid to try working on that project from another version of the Visual Studio..
I found that this answer was asked and answered before VS2010 was actually released.[code]to a .NET Framework 4.0 project in Visual Studio 2010 and it does not compile.Do you now if this feature is really implemented and what I am doing wrong?

I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.

I'm trying to create heirarchy of classes in vb.net. I was able to achieve it in csharp by using the following tags in .csproj
<Compile Include="ClassA.cs">
<DependentUpon>ClassB.cs</DependentUpon>

Below snippet in the solution explorer would be as follows
I need to achieve the same in vb.net.
I'm new to vb.net. Can anybody tell me the alternative of <DependUpon> attribute used in .csproj equivalent in .vbproj. For some reason, this attribute seems to be ignored in the .vbproj even though it is displayed in the visualstudio2010 intellisence.

I have a class assignment and I am having some difficulty with an Access 2010 database and OLE objects in the database. I have the database imported into the project and I am able to view the records from the database that I have in labels and combo boxes.
I used the database DataSoure wizard to create my connection string and import the Access database. In the DataSouce window I set the DataSet for the "Flag" column that contains my pictures to use a picture box object type and added the data bound object to my form.
When I run the application all the field from the database show as expected however, the picture box object does not display the images from the database. When I check the picture box object in the designer the properties window shows that the image source is bound to my database with the little database icon and the data bindings are all correct.
I am trying to write a Project to keep track of my favorite sports teams and scores and store and retrieve the data from a database. I am using vb.net and accdb files. I am able to connect to the tables( 3 tables Players'Keep track of individual stats',OpposingTeams'Keep track of who my team played',Games'matches between the two teams') and Visual studio made it easy to display the teams in comboboxes but this is as far as i can get.
I am wondering how to have a textbox query the Games table and "insert a record into the table, thus creating a primary key and returning the primary key to visual studio and display it in the texbox"

I have a program designed in VB.net for a wafer probing system. The software has 3 main components that come standard and three that are options. When a customer decides not to have the three options they are disabled but still in the program. If at some point they decide to buy the options, one of our technicians would have to go there and be able to access the program with an administrative account to enabled the components.
Does anyone have any suggestions on what the easiest way to accomplish this?

I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?

I'm running Visual Studio 2010 on a terminal server, and have been, with relatively few problems, for some time. This morning I fired up my PC and over the UK's long weekend, the following issue seems to have developed.I've got a bunch of projects (but not all of my projects, and not all of the projects in a given solution) complaining that a particular file (which does not exist on the computer) cannot be opened, and so those projects will not compile anymore. Here's the error:
Error 31 Unable to open module file'C:Users[username]AppDataLocalTemp2.NETFramework,Version=v4.0.AssemblyAttributes.vb':
System Error &H80070003&
I could simply copy the file into that directory and be done with it, I'm pretty sure that will work,EDIT: Okay, now things have gotten to a whole new level of weird. I've rebooted the server, I get the same error message, only now the file it is asking for exists and can be opened in Visual Studio with no problems. another part of the IDE still insists that it's unable to open the module file.
EDIT 2: Can't delete the file because it claims to be open in another program, but I've logged off and logged on again, and there shouldn't be anything accessing it.
EDIT 3: Because there's a wall of comments below his answer, I'll mention here that Jared's suggestion to delete the SUO file for the solutions having the problem (not files specifically to do with any of the problem projects, strangely) was what solved this, eventually.
Will i be able to successfully install 2010 beta 2 side by side 2008? because i want to test 2010 features and some development toolkits such as silverlight while i don't want to uninstall my visual studio 2008 professional.
