SQLite ADO.NET Provider and Compact Framework

By
Well, I spent a fruitless afternoon fiddling with SQLite 3.0.4, 3.0.5 and the Finisar SQLite ADO.NET provider. The provider works great for SQLite 3.0.X but there are serious issues with getting it to work ON the Compact Framework due to the marshaling deficiencies with C-style DLLs in CF.
Bottom line is, even though the provider has a .NETCF solution and test app, they'll compile fine - but they will always throw a System.MissingMethodException on the sqlite_open call.

This, after downloading the C source and recompiling my own SQLite3.dll library, to no avail!

Finally, a look at the Sqlite WinCE site shows the proof: "SQLite 3XXX has serious issues!"

Yeah, so does SQLite 2.8 too, if you want a 100% CF - based DBMS solution.
Disappointed,

Some observations on Script Callbacks, "AJAX", "ATLAS" "AHAB" and where it's all going.

By
I've taken a more than cursory interest in the whole Remote Scripting (.NET species) vs. AJAX and now ATLAS discussion, mostly because I started using Remote Scripting since Microsoft first released it, and because I continued to refine it after seeing Brent Ashley's excellent work with JSRS, which was one of the first "real" cross-browser solutions back in 2000 (that's the turn of the Century for you history buffs). Now Bertrand Leroy, a Microsoft guy whose work I like , has authored some very interesting ASP.NET 2.0 script callback stuff that he points to on his blog, and he is obviously (at least, to me he is) involved quite heavily in the development of this new ATLAS infrastructure that they'll preview at PDC. Leroy's most recent post brings to the surface what I agree are the major differences between the "AJAX a - la .NET" approach as popularized by Michael Swartz with his AJAX.NET library, and Leroy's RefreshPanel, the ASP.NET 2.0 b...

IE7 - Vista: "Internet Explorer has stopped Working"

By
Image
This one was a bitch. All of a sudden for no reason at all, out of the blue, I get this dialog "internet Explorer has stopped working". I didn't install any new software, crap- I didn't do anything! So here I am using FIREFART to go on the internet and find out what to do! Damn! Good thing I've got the sucker on the same machine (I'm not "anti-Firefox", i just don't use it that much except to check my page renderings). The Fix The fix (at least for me): 1) Go into Control Panel, and choose "Internet Options". 2) Under the "Advanced" tab, press the "RESET" button at the lower right: Don't ask me why this happens, or why the fix works. That's a BUG, D00D - I don't care how you slice it!

FIREFOX / IE Word-Wrap, Word-Break, TABLES FIX

By
One of the most annoying things a developer (who would normally delight in writing code, not futzing with markup) can have is getting rendering issues between different browsers. The two biggest players are of course Internet Exploder and Firefart (as I lovingly like to refer to each). In most cases that's going to take care of 98 percent of your total site traffic. IE has had a proprietary "word-break" style attribute for a long time, and this made it into the CSS 3.0 spec. But that doesn't necessarily help you with Firefox right now. Firefox literally - (and I consider this completely idiotic, since it's been in their bug database for FIVE YEARS) does not have a reliable CSS style element to force table cell content to break in the middle of a word in order to stop the content from expanding your table / div off the page or over other content on the page. Here's a partial fix, which will work for most tables and browsers. The style declaration (I call it m...

System.Web.Caching.Cache, HttpRuntime.Cache, and IIS Recycles

By
Recently I chimed in on a newsgroup thread to an OP (Original Poster) who was questioning why he was losing Cache items. This individual would load a dataset from the Cache object into a local object to use to perform processing. He had been using httpcontext.current.cache and noticed that sometimes he was not able to get the dataset out of the cache. He tried switching to HttpRuntime.Cache and it seemed to help. The OP claimed that the application is under heavy hits, and once or twice every month he would see this error. He wanted to know why does the HttpContext.Current.Cache call work sometimes, while some other times does not. A couple of posters replied, one of whom is a respected MVP who usually makes very astute, high-quality posts. He posted," The cache is only valid during the life of the request. how is you[sic] code using the cache?" Somebody else (also pretty astute, usually) responded, "Cache is valid during lifetime of application not request.....". W...

FIX: Requested Registry Access is not allowed (Visual Studio 2008)

By
Symptom: in Visual Studio 2008, you attempt to add a new WebContentForm and associate it with a MasterPage. You receive an error dialog "Requested Reqistry Access is not allowed". Don't ask me what caused this; I'm guessing that the registry keys involved had their access denied due to removal of a previous version of Visual Studio, leaving the new guy (Visual Studio 2008) in the lurch. Here's the fix: Download "subinacl" here . This is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain. After installing subinacl.exe (it will be in the C:\Program Files\Windows Resource Kits\Tools folder.), drop to a command prompt and run the following batch file, which you have saved in the same folder with the filename "FIX.bat": subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudi...
