• Visual C# FileSystemWatcher to monitor directories not working.

  Hi all, Hopefully someone can help me find a solution to a problem i'm having. I have an application that downloads files from an FTP site to a specified download location. The application then launches an SSIS package to process the downloaded directories. What i want to do is set up a FileSystemWatcher object to monitor the download directory. As the SSIS package processes the directories it removes them to an archive or quarantine location. As they are removed i want the FSW Changed event to fire and to update a label in the application to show the number of directories remaining in the download folder. Can someone polease nelighten me as to how this can be done. At present the FSW Changed event doesn't seem to be firing and i don't knw ...Show All

• Windows Forms Basic question about using custom files/classes

  Hey there, I know C++ fairly well and in order to learn Windows Forms I decided to make a calendar application. Here is the layout i spent some time on using the designer. (the main parts including the days arent included yet due to my problem) I have no problem making simple interaction with these controls, for example. I have the "Next" and "Previous" buttons scroll through the months of the year, and the corresponding year is displayed in the label above the buttons. This was simple for me to figure out because I declared and used my integer(identifies the current month) right in Form1.h. However, as almost all applications, my project requires custom classes and files. So, say i want to create MyFile.cpp and My ...Show All

• Community Chat Free Online Visual Basic 2005 book

  I have recently made my book free, sponsored by AdSense of course. The book is designed for non-programmers. After many hours of tweaking javascript I have finally completed most of the design of the page, so that it works with google and also so that there are no frames. If anyone would like to help with the book, ie: make it better, then feel free to contact me here or at the site. You can find the book link in my signature... I am thinking of using DP Syntax Highlighter ( http://www.dreamprojections.com/syntaxhighlighter/Usage.aspx ) for highlighting the code, and also adding C# to it. Perhaps even C++ I would need some help with this though, as I'm not really that great in those two languages. If anyone wants ...Show All

• Visual Basic Desktop folder question

  Hello, I was using the "My" namespace to reference the Desktop folder, like this: My .Computer.FileSystem.SpecialDirectories.Desktop but it was not showing all the contents of the folder. Another person said that the "My" value returns the filesystem folder corresponding to the desktop and not the Windows shell desktop folder. Is there more than one Desktop What does this mean Thanks for any suggestions. The following My.Computer.FileSystem.SpecialDirectories.Desktop will simple return a path to the current user desktop folder. Every user has there own desktop folders and you can then use something liek the following to return all the files in the folder ...Show All

• SharePoint Products and Technologies Page Viewer Web Part Problem

  I am unable to display files in the Page Viewer Web Part as the MS documentation says I can. When I select "File" from the Web Parts properties, no Browse button appears (as the documentation says it should) and if I try to enter the path to the file manually, the system always tells me it is invalid. Is this working for anyone else out there If so, please tell me what I am doing wrong. I am running WSS 3.0. Please note, I can display a web page in the Page Viewer Web Part without any problems, so I know that aspect of it works. There's no "Browse" button; you just enter the URL of the file in the "Link" text box. Remember that you have to enter an address that will be accessible by the end user ...Show All

• SQL Server LOCAL USER vs GLOBAL USER set in agent service

  My replication is not working. I was able to create a transactional replication successfully. However, when i tried starting the agent on the snapshot, it wouldn't work. I figure that it was because my agent service login is different from that of the subscriber. my publisher and distributor is on local user whereas my subsciber sql services use our global login. Thank you in advance.

• .NET Development Can class instances be reflected without giving reflection a reference to the object?

  If I have a program in which I've declared a few instances of a class, is there some way I could write a reflection component that could be plugged into this program and read instance information off of the class(es) without reflection being passed a reference to the instances I can already read all the information off public properties and fields of a class instance when I pass a reference to the instance to my reflection code, but I don't want to have to pass an instance, I want reflection to discover what instances exist in a program and read their public property information off of them. This won't be possible using managed code due to the architecture of the CLR. The only point at which you can know where all of the objects a ...Show All
