Glass Effect in XP using dwmapi.dll - C# Discussion Boards

Hi
I want to write a regular expression to validate my experience field. This field excepts numeric(year) value and decimal(month) value.

For Ex: 4.3(4 yrs and 3 mnths)

I want to validate my texbox value using regual expression so that year is not more than 12 and month is not more tha 11. I need help as early as possible.

Thanks in advance

i think for this you can use Range expression validator instead of Regular Expression

HI Experts..

Plz do reply soon.. Thanks in Advance.......

Hi, I have a xml file with more than 1 GB size. I have to read the xml node value from the xml file. I can load the xml file and then read the value of node, but If I load the file its decrease the performance of the application. Is there any other method by which I can read the node value without loading the xml file ?

Using XMLReader might be one way.

Reply Me fast please

Windows XP does not support glass effect, it's Vista only.

I think understanding your post itself a time consuming one instead how can you expect a fast reply...

I'm impressed.

If you succeeded in copying all the dlls required for the vista glass (which of course you have not) and placed them on Windows XP then you would not have XP anymore but vista as you will need the entire vista operating system for glass to work.

If you have knowledge, let others light their candles at it.

Well, I mean an icon that acts as a visual indicator of something in the notification tray. What do you mean by notify icon, why ask for VB in a C# forum, and who put the ang in the boomshangalang?

Sometimes you are so stoopid Pete!

No one put the ang in the boomshangalang, it's always been there; 'boomshalang' just sounds silly.

You see, I assumed it was the same person who put the bop in the bop-do-wop-shoowop.

You can probably try express editions[^]. I think those are free.
