I guess you want what VSS calls Next/PreviousDocumentWindow. By default, it's on Ctrl(-Shift)-F6 on my VSS 8. On Ctrl(-Shift)-Tab they have Next/PreviousDocumentWindowNav. You can change key assignment via Tools/Options/Keyboard. |

Best use pattern for a DataContext |
|linq-to-sql|.net-3.5| |
What's the best lifetime model for a DataContext? Should I just create a new one whenever I need it (aka, function level), should I keep one available in each class that would use it (class level), or should I create a static class with a static DataContext (app-domain level)? Are there any considered best practices on... |
Creating batch jobs in PowerShell |

Imagine a DOS style .cmd file which is used to launch interdependent windowed applications in the right order.

Use an installer with a worked out script. Any installer like Wise, InstallShield, InnoSetup, etc will probably do. |
Use the cut command.
e.g. echo "system-source-yyyymmdd.dat" | cut -f1 -d'-'
will extract the first bit.
Change the value of the -f parameter to get the appropriate parts.

Thanks for all the input, it looks like the short answer is 'No you can't (well not nicely anyway)', so I'll have to do it the hard way and add the conditional code. |
One way I have done is to use ::CryptExportKey() to get the PRIVATEKEYBLOB or PUBLICKEYBLOB.
From there you can use the PUBLICKEYSTRUC and RSAPUBKEY to extract the various key components and write a key data xml file that looks like this (base64 data removed):
<RSAKeyValue>

Ok, forget the last answer I can't read :) You are working with 3Des keys not RSA keys.

You should get familiar with the [Mono project][1] and [MonoDevelop][2]; the express purpose of those projects is to allow building and running .NET code on a variety of platforms, including Windows, Linux, and Mac OSX.

This should give you a list of all columns in the table "Person" that has only NULL-values. You will get the results as multiple result-sets, which are either empty or contains the name of a single column. You need to replace "Person" in two places to use it with another table.

You can't do this with the base dict class -- it's ordered by hash. You could build your own dictionary that is really a list of key,value pairs or somesuch, which would be ordered. |
You should also note that the inline keyword is only a request. The compiler may choose not to inline it, likewise the compiler may choose to make a function inline that you did not define as inline if it thinks the speed/size tradeoff is worth it.
