Free An RCW That Is In Use?
Feb 10, 2010
I have a loop that uses threading to manage an untrappable error in a function that runs from Excel. If the function processes with out issues, Excel closes. However, if a time out occurs Excel cannot close and the following error occurs: "An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss."
The error occurs at FinalReleaseComObject(Me.xla) xla.Type is Excel.Application and Excel will not close unless it is released.
How can the thread be completely closed when a time out occurs?
How can the Runtime Callable Wrapper, RCW, be freed from use?[code]...

I need something like ObjectListView and LGPL, BSD or some license that allow its uses in commercial applicatioTo use ObjectListView commercially, companies normally buy a license. A license to use ObjectListView commercially is 100 euros for small companies or 500 euros for medium sized companies. This license gives the company permission to use ObjectListView in any and all of its closed source applications. The license fee covers the current and all future versions -- there are no upgrade fees

The problems:
I can't use string.Format, I have C style format strings;I can't call the native printf (no P/Invoke);I can't use http://www.codeproject.com/KB/printing/PrintfImplementationinCS.aspx because of the license, I need something GPL-compatible.Is there a free implementation of printf/sprintf for the .net framework? Other than the above link, I couldn't find anything.
I cooked up a sprintf function that supports basic format strings, you can find it here: [URL].. I'll try to make it a complete implementation if I can.

Create large size files for a customer. The more we use ram memory as faster the program will run.
Is there a way to global find out in vb 2008 how much free ram is available?

I was wondering if you could tell me of any free libraries for the .NET framework (2.0) that you know of that can convert a PDF file to HTML or XML. I've seen several components that do the opposite, meaning HMTL to PDF, but not what I need. Essentially, I need the html version of my PDFs because I need to search through the text. Also, the Adobe Acrobat SDK is not an option for me, even though I know it has the exact functionality I need.

I'm kinda new here, and I didn't know what forum to put this in, so I just put it here. I wanted to load an assembly to an Application Domain, use it, then unload it when I'm done with it. The assembly uses too much memory. The problem is: After I unloaded the assembly, the memory used is not getting freed. I was watching the performance all the time. The available memory increases only after I close the whole application. And that assembly is the only thing that uses a lot of memory in my application. Here's the code I used to load and unload the assembly: How can I free up the memory without closing my application. The memory was suppose to get freed up by simply unloading the assembly that uses it much.

I've been looking for a free library/source code to format SQL queries, preferably in .NET, for quite a while. Even after searching some of the responses here on SO, I'm almost at the point where I'm willing to believe that nothing like this exists. The closest thing I've found, a project called sqlformat, does not seem to be active, nor does it really even support a workable subset of SQLs features for formatting.Are there any free or open source SQL formatting libraries out there? I don't want a canned product, as I need to integrate this functionality into a tool I'm building. Web services aren't acceptable either, since the ones I have found like T-SQL Tidy haven't proven to be very reliable.

I was wondering if there were any free ribbon controls for vb.net, and if there are not, how I could go about making my own. I don't want to pay $300 or more for a professional one...and I would really like to add one to my project.
What would be the best solution for finding/making one?Here is my google search I tried, I could only find one for c#. If possible, I would like one which is the closest to the one used in Office 2007.

if (String.IsNullOrEmpty(Title))
yield return new RuleViolation("Title required", "Title");
