Hi, I think, that it is not possible to count number of tries on client side, because you can't check if login information is correct on client side. You need postback to do this. I think, that better idea is to store number of tries on server side using Session or maybe ViewState, but I'd prefer Session, because it is more secure (unless you are using ViewState encryption). But if you want to prevent user (Hacker?) from trying to login more than three times you should save number of tries in database associated with his IP adress, because if you store this in Session it is not problem to open new browser window and try anotrher three passwords... // code in event handler on server side (asp.net) int tries=0; if (Session["logintries"]!=null) tries=(int)Session["logintries"]; if (tries<3) { // check password... if (invalidPassword) tries++; } else { labelError.Text="No no no.."; } Session["logintries"]=tries; Tomáš Petříček (Microsoft C# MVP) www.eeeksoft.net | Asp.Net Graphical controls

Thanks for the reply. The exception information is: An unhandled exception of type 'System.NullReferenceException' occurred in codeProjectWs.exe Additional information: Object reference not set to an instance of an object. When i use the same code to the the messageBoards brief, it works just fine. it seems as if the web service isn't functioning properly. as for the .ToString, i get you. Thanks again.

I have the same problem. It just feels more natural, and easer to read/write (x==7) instead of (7==x). But good habits (a.k.a constant==variable) are good habits. I keep trying to break this one, but habits are haibts.:) Trust in the code Luke. Yea right!

Can you post the code from your dynamically loaded DLL for the propertypage class. It could be that when the page gets registered, it oly uses the CPropertyPage base class and not the CYourPage class when the message map entries are getting processed. Also the code which adds the page to the sheet may be useful in understanding the problem as well. Roger Allen Sonork 100.10016 Were you different as a kid?

I had a similar problem recently on NT4, my keyboard changed to German layout from UK English. German had been set as an "input locale", but I was using my default, English, my only "cure" was a reboot I assumed something had screwed up the PC. The obvious question, if you run the code onto another PC what happens If I have seen further it is by standing on the shoulders of Giants. - Isaac Newton 1676

I think that you can only set a BMP wallpaper with that API. To use a JPG you need to turn on ActiveDesktop and use the IActiveDesktop interface to set a wallpaper. --Mike-- If it doesn't move and it should: WD-40.
