Use Windows API Code Pack In 2010 Express?
Apr 14, 2010
I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources.
Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?

I'm compiling and testing the VB programs in a download from MS of the Windows API Code Pack at url...(which is in VS 2008 and needs to be converted to run on VS 2010). So far I've resolved most of the issues, but a couple are baffling.The code as downloaded for the Taskbar demo refers to icons in the project resources as My.Resources.Green and My.Resources.Yellow and Red. Fatal errors, even though all the help pages say this is the correct way to access them. I got the build to run by removing the "My."; has there been a syntax change between VS 2008 and 2010? When I run the app, I get a message from TaskbarDemo.vshost.exe which says "This demo application needs to register .txt files as associated files to properly execute the Task related features. Filetype is not registered." Does that mean that in trying to debug the app, I have to modify the registry to associate the test program with the .txt filetype?

I am looking for verification on whether Application Restart and Recovery APIs work on Windows Vista or not. In the documentation the introduction says it designed for both Windows7 and Vista. Windows API Code Pack for Microsoft® .NET Framework provides a source code library that can be used to access some features of Windows 7 and Windows Vista from managed code.I did surf thru the issue tracker on the API home page, nothing mentioned on restart/recovery issues.
In the download, there are two sample projects specific to restart/recovery of an application, which has stopped responding (AppRestartRecoveryDemo), one in VB.NET and the second in C#. I tried both with dbWin32 to monitor that various operations ran and that there were no exceptions raised. All operations ran without raising an exception other than the restart failed and the initial recovery worked. Before working with the above projects I did rebuild the core libraries rather than use the supplied binaries.
When first running the project you must wait 60 seconds for recovery/restart mode to be possible along with registering for recovery using the following.
ApplicationRestartRecoveryManager.RegisterForApplicationRestart( _
New RestartSettings("/restart", RestartRestrictions.None))
I changed the restrictions above seeing if this would make a difference in regards to restart failing but it did not.In RegisterForApplicationRestart a check is made to ensure the app is running at least under Vista ThrowIfNotVista It works as I am on Vista. Next RegisterApplicationRecoveryCallback sets up the callback method (see figure 1) to invoke when the app crashes. So when a crash occurs I have verified all code up to Debug.WriteLine("Application shutting down...") executes in the Recovery callback and assume that ApplicationRestartRecoveryManager.ApplicationRecoveryFinished(True) and the return statement execute, as there are no exceptions thrown.
After the recovery callback method finishes I expect the app to restart. The "application is not responding" dialog says that the application will now restart but instead the application closes and never restarts. I am curious if someone else has worked with recovery/restart API and had success on Window's Vista to restart an application.' This method is invoked by WER.
Private Function RecoveryProcedure(ByVal state As Object) As Integer
Debug.WriteLine("ARR: Recovery procedure called!!!")
PingSystem()

is this even necessary in VS2010 & .NET 4.0? I've been trying to take advantage of the new Windows 7 taskbar interfaces like the Jump List. The MSDN documentation/tutorial instructs me to include a System.Windows.Shell, but apparently Shell isn't a member of System.Windows. I downloaded the API code pack, but I am unsure of what to do with it. The instructions say to open the main solution file and build it:QuoteTo build the library (except the DirectX related features) in Visual Studio 2008, please extract the contents of the �WindowsAPICodePack.zip� file in a new folder and build the included �WindowsAPICodePack.sln� file.And so I did that, but that is the extent of the instructions. I thought maybe it was a Visual Studio extension, so I tried accessing Shell again to no avail. Do I need to add each of the respective namespaces' projects to the target solution to use the API Code pack?

I decided to have a play around with the Windows API Code Pack and so far it has had some very interesting things. Something which I like in particular is AeroGlass. I have created a project to mess around with it to see how it works etc. and I am having some difficulties with the tranparency. If I put a textbox on the form for example, it displays fine. The text however is barely readable unless the form is over a dark background. The solution seemed obvious. Change the transparency key. However, there wasn't one set. Adding one stops the glass effect from working.

When trying to install on another PC I get the error message "Microsoft.VisualBasic.PowerPack.Vs Version 9.0.0.0 be installed in the Global Cache (GAC) first" I have already installed the .NET 3.5 and the PowerPack but I still get the message.

I am learning VB for the moment. I want to copy/paste code from a PDF to Visual Basic 2010 Exppress, but if i paste the (structured in PDF) code to VB, i get 1 long string of code and need to restructure it by entering after each line. Otherwise VB gives me a lot of errors. This is a time consuming work. Isn't there a way, VB puts the code in the right format?

This sounds like a dumb question, but I'm using VS 2010 Express edition and cannot find where to add a new Windows form. The templates provided don't indicate a Windows form . Are they called something different in this version of VS?

There were several reference to compiling the program using x86.
Go to Project menu -> Properties -> Compile tab -> Select "Advanced Compile Options" -> Select "x86" instead of "AnyCPU"
I followed the path and there was not any option to select x86 in VB 2010 Express.

I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?

I had no errors in my VB project it was compiling nicely. I loaded SP 1 today and now I have 102 errors. Actually I'm sure more than that as 102 is the max it will show. It particularly doesn't like the date functions and isDBNull. And it balks at vbcrlf now. Here are some examples of the errors I'm getting:

I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

The function checks for the input only the digits.

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.

I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Is VB Express 2010 slower to compile and run that older versions of VB Express? I've installed it this weekend and it seems a little sluggish on my quad core computer with 1 gig of RAM. I have VB Express 2005 installed for my students at school and it seems to fly just fine. Those school computers are older P4s with 512k of RAM.

Initially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).
