Increase IIS on XP Maximum Connections

-
With increasingly more complex web pages, I found myself running into a limit in the number of IIS connections allowed for the constrained web server on Windows XP. By default Microsoft has limited the connections to 10. Even when I changed the time to release connections down to 5 minutes, I was still running into problems. With a little Google searching, I found a solution (here, here, and here).

Apparently the hard-coded limitation Microsoft has set is 40 connections. The trick is determining how to raise the level from 10 to 40. There's a script, adsutil, that can do this for you.
  1. Go to the Command Prompt and navigate to C:\Inetpub\AdminScripts.
  2. Enter "adsutil set w3svc/MaxConnections 40".
  3. If you get an error message, "This script does not work with WScript," click OK and click Yes to make Cscript as the default script for VBscript.
  4. When this completes, go back to the Command Prompt and press F3 (repeats last command) and Enter.
  5. If you were successful, the command should return "MaxConnections: 40".
  6. Stop and start IIS. You can do this as the same Command Prompt by entering "iisreset".
I suspect there may be a Registery equivalent setting, but this did the trick for me. If you don't need IIS to begin with, perhaps a better solution would be to load Apache. Microsoft Visual Web Developer may also be a solution, though I haven't spent much time with it myself.

I have continued to have some issues with IIS crashing from time-to-time.

Microsoft has a utility that will spill a log file when IIS crashes (http://software.techrepublic.com.com/abstract.aspx?docid=790867), but it was of little help. Crashing while trying to load .GIFs and .JPGs.

I turned logging off in IIS, and this also bought me some performance, but still I experience some issues.

I've concluded that if I'm going to continue to use/support classic ASP, then developing is going to require me to either have and test my files on a server (connect to Windows Server 2003 or 2008) or replace my XP OS with Windows Server 03/08.

Digital Signatures in PDF Do Not Print

Trouble getting the digital signature in a PDF to print? The solution is actually simpler than you might think. With your document open in Adobe Acrobat Reader, click File >> Print. When the Print dialog box opens, look for the "Comments and Forms:" drop-down below the Properties button, located in the upper-right. Click the drop-down and select "Document and Markups." Now print. That's all there is to it.

Referencing the value of a cell, not its formula

-
Image
In Excel, I will use formulas quite frequently for my analysis. At times I want to reference the resulting value of the formula for comparison or to feed another formula. Unfortunately, if you are doing a comparison, Excel will try to compare the formula instead of the formulas results. Well, turns out there is an easy way to correct this. If you want your formula result to be a number, then use the VALUE function. If you want the formula result to be text, use the TEXT function. Here is the syntax for each: VALUE(text) TEXT(value,format_text) -- The format_text value can be any format from the Category box on the Number tab (in the Format Cells dialog box) except General. Here is an example of each: =VALUE(MID(A2,46,FIND("&",A2)-46)) -- this actually finds a number beginning with the 46th character of a string, and continues until it finds the ampersand character. By wrapping the formula with VALUE, I can now compare the number to other numbers in my looku

CorelDRAW X4 Crash on Startup

-
I had a fresh install of CorelDRAW X4, and each time I tried to start it, it would crash. After some searching through Google, I found the following fix. Open the folder C:\Program Files\Corel\CorelDRAW Graphics Suite X4\Programs\UIConfig\CorelDRAW Edit DrawUI.xml Find the line <dockpage guidref="bc1e2f70-3b58-41cd-8406-aaa550482972" visible="true" selected="true"> Change visible="false" and remove selected="true" <dockpage guidref="bc1e2f70-3b58-41cd-8406-aaa550482972" visible="false"> Save and close DrawUI.xml Fold down F8 and restart CorelDRAW X4 When prompted to update settings, select OK That did the trick for me. Apparently it is caused by a conflict with MFC dlls that are installed (version 1833) with SQL2008.
