Use Windows API Code Pack In 2010 Express?
Apr 14, 2010I 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?

Apr 4, 2012I 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?

Proper Update And Delete Code For SQL Express In 2008 Express Edition?

Unhandled SqlException In VB 2010 Express Thta Does Not Occur In VB 2008 Express?
Oct 16, 2010I 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.

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.

Jun 3, 2011Initially 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).

View 3 RepliesVS 2010 - Applications Made Using VB 2010 Express Expire After Some Time?
Nov 3, 2011Here are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?

Is It Better To Start Learning C# Or C++ In .NET World
Mar 25, 2011I have some very rusty C++ and lots of C experience, but have done little OO design or coding.I've started learning C++.NET as that seemed to be the best starting point.I've hit restrictions in Microsoft's provision with multiple inheritance and extensions, neither work in C++.Would I be better off starting again with C#, or am I better off using a mixed language approach. eg. extensions in C#, rest in C++?I'm still struggling with this->method or that.property and theother::staticthingy or whatever, and this probably is not an issue in C#. You'll see what I mean as that probably isn't the right way to desribe the difference between '->' '.' and '::'I'm getting to achieve what I want, but it's taking me 10 times longer than I think it should.
