I have recently obtained the files for the old Dr Dobbs Challenge and wanted to use them to help my 13 year old grandson learn programming. All other sources of help seem to have dried up. The project file indicates Visual Studio # 2008.
I downloaded/installed VC# 2008 and Silverlight but VStudio won't load the project and reports incompatibility errors. I should say I also have VS2005 and VS2010 (C# and C++) as well as AVR Studio 5 (uses VS2010) on the computer, could there be a conflict?
Please help! what do I need to change.

I think you may have to be a little specific about the errors you are getting. VS2010 should open it and offer to convert the code for you but you may have to manually correct some things. If possible I would search for other similar examples to download that are a little more recent. Maybe google can assist you.??

I can't believe I need 2010, it wasn't released at the time of this project.
The actual error message is two lines, " The project file "C:\~~~~~ .csproj' cannot be opened" followed by "The project type is not supported by this installation"
NOTE: I replaced the path with ~~~~~ .
This is a standard installation of VS2008 Express and Silverlight as specified.

You might also want to take a look at Small Basic. The tutorial is great for young beginners.

I have already exposed him to 6+ months of Small Basic and he has done well. I figured it was time to move on. Small Basic is good but in a limited way and it certainly isn't like any BASIC I grew up using. I guess that's why it's called "Small Basic". If we continue with BASIC it will probably be Dark Basic.

Try SharpDevelop, it will generally open VS project/solution files and it's free and good.

Thanks, I will look at that.
However the original project was for VC#2008 so i am hoping i can resolve the problem (with help).

Can you post the errors here? Or a screenshot?
Alternatively, you can try opening it with VS2010.

Could you actually post the link to the download? If you do, I'll download it and take a look later on tonight.

I downloaded it some months back. The zip DDC2.zip is 3Mb so i don't think i can post it here
|

Just the link to the original if you can find it. My suspicion is that it supports solution folders (which would indicate this is a VS Pro or above version) and you have an express edition. Alternatively, there is content in there such as C++ or VB.NET and you are using a language specific edition (e.g. Visual C# Express 2008).

I'll look tonight but suspect i no longer have a link.
Can I mail you the zip ??
|
|
|
|

I don't give out my mail anymore - I got inundated with people requesting WPF help from here on CP.
|
|
|
|
|
Understood, thanks.
I will look tonight to see if I have a link, but the more I think about it, I believe I downloaded it from DrDobbs or Gamasutra.

I found a link to an advert for it, and it seems to indicate that a full version of Visual Studio is required. I'll pretty much guarantee that it's using Solution Folders, which you can't use in the Express editions.

Interesting, but alas I only have the Express version. I thought that when i downloaded it, it included links to Silverlight and Visual Studio Express 2008. However, as an open competition, I would have expected the free Express version.
Thanks for your thoughts, i will keep digging.

According to this MSDN blog it was the free trial version, but that could have been the time limited full trial i guess. I will see if i can still download it. http://blogs.msdn.com/b/silverlight/archive/2009/04/20/dr-dobb-s-challenge-deuce-play-modify-win.aspx

Alas, I downloaded Visual Studio 2008 Pro 90 day trial but i get the same result when attempting to load the project. I think i need to abandon this. Read the source code, keep the resource files and recreate something from scratch.
|
|
|
|
|
the source code references www.dobbschallenge2.com but that is a dead link that opens the main Dr Dobbs web page.

I think the suggestion for Sharp Develop which is available free from Codeplex website is your alternative. It looks and feels alot like VS and you won't be disappointed. Try it out at least to see if you can open the solution for the young programmer. If it doesn't work you can always uninstall it.

I'm having trouble getting the different line weight. Let's say to have cells from A1 to A3... I would like to have the border to be medium weight continuous line around this range, while having the hairline hortizontal line inside.
This is what I have:
xlRange = (Excel.Range)xlWorkSheet.get_Range(Cell_1, Cell_2);
xlRange.Borders.Weight = Excel.XlBorderWeight.xlMedium;
xlRange.Borders[Excel.XlBordersIndex.xlEdgeBottom].LineStyle = Excel.XlLineStyle.xlContinuous;
xlRange.Borders[Excel.XlBordersIndex.xlEdgeLeft].LineStyle = Excel.XlLineStyle.xlContinuous;
xlRange.Borders[Excel.XlBordersIndex.xlEdgeTop].LineStyle = Excel.XlLineStyle.xlContinuous;
xlRange.Borders[Excel.XlBordersIndex.xlEdgeRight].LineStyle = Excel.XlLineStyle.xlContinuous;
xlRange.Borders.Weight = Excel.XlBorderWeight.xlHairline;
xlRange.Borders[Excel.XlBordersIndex.xlInsideHorizontal].LineStyle = Excel.XlLineStyle.xlContinuous;
I got hairline weight continuous line in this on around each cell in this range... huh?

these are the two weights I want... the medium would go around the range of cells, while the hairline is inside horizontal lines. I wish I could post an illustration in this post as an example.
