Parameters ignored when passed to Crystal Reports .net

This is a crazy, crazy annoying bug. Basically, when the Crystal Windows Form Viewer is added, the auto-generated code adds two lines that will overwrite the selection formula!!!

Answer came from

https://stackoverflow.com/questions/10584989/select-criteria-not-working-in-crystal-reports-and-visual-studio-2010/15421308#15421308

Resolution

To resolve the issue, follow these steps:

Expand Form1.vb|cs to show Form1.Designer.vb|cs. (form1 denotes the form that contains your viewer)

Double-click on Form1.Designer.vb|cs to show its code.

In the InitializeComponent method, you will find code where the CrystalReportViewer1 properties are set.

Comment out or delete the following two lines:

me.crystalReportViewer.SelectionFormula = ""

me.crystalReportViewer.ViewTimeSelectionFormula = ""

Random ways to cause Bluescreens (For Testing)

The most common is to

  • Open Regedit
  • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
  • Add a new DWORD (32-bit) Registry value here with name = CrashOnCtrlScroll and value = 1
  • Now you close regedit and restart PC
  • Finally hold down Right Ctrl and press Scroll Lock twice to trigger the BSOD.

This can never work through RDP though. So other methods

This might work, but slow

This works well to crash a machine on boot

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ACPI]
"Start"=dword:00000004

Save it as a .reg file and run it. Your computer will blue screen on reboot. Return to last good configuration or change the value back to 0 to fix it.

This also works

The command line interface for the DiskCryptor Open source partition encryption software includes a -bsod parameter, the wiki says it will

@Tile_App I love you, but one suggestion

So I found some guys keys on the road. It had a tile on it. I was like sweet I should be able to return these easily.

But no. There is no way to email the owner that I found his keys.

It would be better if he scrawled his phone number on the back of the tile, at least I could call him!

So, Tile. How about you add a feature to the Tile app. Found a tile

You press the big E, it snags the serial number (I’m guessing its broadcasting it anyways, I didn’t try to sniff the blue tooth traffic) and lets you message the owner.
