I have a utility that is a simple exe that is not installed compiled with VS2005 and works well. But when I upgraded to VS2008 the utility can no longer locate files in the active system folder. I have UAC turned off and am logged in as the Administrator and it still can not locate a file that I can see in Windows Explorer. The file I am looking for is PakMgr.exe.

Currently I am building a Canon EDSDK Application using VB.NET that access a Canon 500D camera. It's a DLSR system. I've read that the EDSDK is only working on 32 bit system, thus my application only capable of running on a 32 bit system.
But, I just installed DLSR pro [URL], it can access my camera, regardless of the operating system : 32bit/64bit.
How do they able to do it?
Is there a new EDSKD that can access camera in 64 bit OS? I am using a 2.6 EDSDK.
I have a vb .net application where the user can choose a directory into which an excel file is written. If the user selects a system directory (yes, my users do this, don't ask me why) then a System.Runtime.InteropServices.COMException is thrown at runtime. I am handling this exception telling the user to please select another directory.
View 1 RepliesI have built a recursive file system crawler that amasses file system data from a file share. I use the FileInfo object to get my metrics, however, I am finding that in especially deep file structs, that the ol' 260 character MAX_PATH MS bug crops up ':8-0:'. This puts me in my angry place, since I do not seem to be able to get around it no matter what kind of programmatic tom-foolery I try.
So far, I have tried:- converting to 8.3 format --> no good path + filename STILL is > 260 (believe it or not) - tried to go with a Straight low-level API approach
What I have found is some pretty Sketchy information regarding VB implementation of the kernel32 api's in this regard (just try & find a createfile port for vb.net, I couldnt)
Anyway, I guess I was hoping that someone else has run into this pain, and knows how to make a surefire way to get a file's information (size, dates esp), regardless of how long and painful the path may in fact be...

View 3 RepliesI have used log4net in winforms before. First time using with a wpf console app. The console shows up and the console appender works exactly as in the winforms app. However in winforms I never had to give the full path to the log4net xml file. It is located in the same place where all the cs files are. (the default place where VS 2010 puts all its source files. So
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo("log4config.xml"));
works in a winforms app's Program.cs->main() but for the wpf version where I have my own Startup class with my own Main() (instead of the autogenerated and hidden main()) I have to change the line to look like this
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"c:fullpathlog4config.xml"));
This took me quite a while to nail down so I thought it may be worthwhile to figure why this is so. Anyone know ? I am using log4net ver 1.2.10.0. The log4net dll and xml both have copy to local = true in winforms and wpf.
I'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!

I have finished coding an application which I designed for people working in my office. When I started to install the application to computers at the office, I realized that, in some machines, application doesn�t work properly. Although it worked for 15 computers perfectly, for 3 computers following error code is displayed:
System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
