.NET Forum / ASP.NET / General / April 2008Page Members not initialized
Hello, i am really confused. I am working on a ASP.NET project. Language VB, Framework 3.5. I want to describe the behavior: Calling a page (including datagrid and a userctrl) I get zero pointer exceptions. When start the project in debug mode I can see that all members and fields of the page like Master and so on are all nothing, including that ones that cannot be zero / nothing! Now the weird thing: When I make a breakpoint (in my case in preinit) all instances of the page are created fine and the page is loaded :/ Does anybody has heard of that problem? And I tried long to figure it out, but the strange thing is that I did not work on that part of the project. It was like from one day to the other day that that error appeared. And its the same in release version. Also the designer shows the page without errors and the partial designer class looks fine too. thanks for all hints, Holger Sorry but you will have to rephrase... I can not make sence out of folowing statements that almost contradict each other 1. >"When start the project in debug mode I can see that all > members and fields of the page like Master and so on are all nothing" 2. >Now the weird thing: When I make a breakpoint (in my case in preinit) > all instances of the page are created fine and the page is loaded :/ In case #1 how do you see all members and fields if you did not set breakpoint? Page object initializes only when called (via browser) and disposed immediatelly once HTML is rendered. Hence you need to break somewere between those 2 events to see all members and fields. So pretty much behavior is expected given you can explain what you mean by "I can see that all members and fields of the page ..." in #1...

Page object initializes only when called (via browser) and > disposed immediatelly once HTML is rendered. Because the debugger fetches the exception an breaks at the first null pointer exception. In my code is that a usercontrol. There I can watch "me" and see that all members including Master are not initialized... ty holger The first thing I would do is run through all of the page events and make sure you did not unwittingly destroy the page through code you added. I would then step through the entire page (possibly even into the .NET code (http://tinyurl.com/yqsokg)) and see where the values are getting munged. Another option is to manually clear out the ASP.NET temporary files, found under %WIN_DIR%/Microsoft .Net/Framework/v{version number}/Temporary ASP.NET Files. If anything is munged there, please post back, as I have been following issues with files here and informally cataloguing them (have posted one bug based on them). Worst case, exclude the page and set up a new page with the same code. You can do this with a simple copy and paste operation. If this works, then .NET is holding something somewhere.

The .NET debugger brought not much... Will try it tomorrow again. The 3.5 directory has no temporary folder. Maybe its located somewhere else? If nothing works I will have to make the page again. holger 3.5 temp files under the 2.0 directory, as it is an add on to 2.0. Sorry for not mentioning it. SignatureGregory A.

But i am not really happy.. I moved the code from pre_init to page_load. Now it looks like the error is gone. I tried to clear the temporary asp files and I created a new page... That did not work. So it looks like that for some reason the page doesnt init correct. I tried to debug it but that doesnt make really sence, because like i said, when I breakpoint in pre_init everything looks fine... Only when it runs without the breakpoint the objects there are uninitialized and the exceptions are caused. Than I am not sure if it has something to do with the clearing of the asp temp folder or if its normal because of the new .net debugger settings. I get tonns of first chance exceptions after first project start (when webserver starts first time). The first comes in mscorlib.dll! System.Globalization.CultureTableRecord.CultureTableRecord(string cultureName, bool useUserOverride) Line 756: Culturename "uploads" ??? A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll A first chance exception of type 'System.TypeLoadException' occurred in System.Web.dll 'WebDev.WebServer.EXE' (Managed): Loaded 'C:\Windows\assembly\GAC_MSIL \System.resources\2.0.0.0_de_b77a5c561934e089\System.resources.dll' A first chance exception of type 'System.TypeLoadException' occurred in System.Web.dll ... (about 100 times ;) A first chance exception of type 'System.TypeLoadException' occurred in System.Web.dll 'WebDev.WebServer.EXE' (Managed): Loaded 'C:\Windows\Microsoft.NET \Framework\v2.0.50727\Temporary ASP.NET Files\root \dc083b87\b1353192\App_Web_ur8tsq9t.dll', Symbols loaded. A first chance exception of type 'System.TypeLoadException' occurred in System.Web.dll When i break into such an exception its something like: Type System.Web.UI.WebControls.WebParts.ContentPlaceHolder in Assembly System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a could not be loaded. Type System.Web.UI.ContentPlaceHolder in der Assembly System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 could not be loaded. Type System.Web.UI.Image in der Assembly System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 ... Maybe its a normal behavior and I can ignore it. But i am interessted in the reasons for that... Other Question: It doesnt save the symbols permanent. Should it? I need to click Load Symbols every time, also when I still loaded it in a previos session. thanks a lot for all replys holger Free MagazinesGet these publications absolutely FREE for up to 12 months.
