I'm trying to get my head around this issue, on a few of my functions i get a warning " 'functionDealWithHiddenFields' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used."Example function:

How can I handle the above warning? Should I just return nothing when an error occurs?

I'm trying to use ResolveUrl() to set some paths in the code behind of a custom ASP.NET user control. The user control contains a navigation menu. I'm loading it on a page that's loading a master page.When I call ResolveUrl("~") in my user control it returns "~" instead of the root of the site. When I call it in a page I get the root path as expected. I've stepped through with the debugger and confirmed, ResolveUrl("~") returns "~" in my user control code behind.Is there some other way I should be calling the function in my user control code behind to get the root path of the site?

I know the error and why. I am just curious. For some projects this show up as warning while for others this doesn't show up at all.
How do I set up so that the warning show up?

My development machine runs Windows XP, but the target machine runs Windows 2000 with .NET 2.0.I've set my compile options to compile 2.0, which is fine.However, I have some references which are causing issues.For example, Microsoft.Office.Interop.Outlook.dll - in VS2008 the path is shows as the C:Windowsassembly folder which works fine. Until the app is built and run on the target machine and fails:Could not load file or assembly 'Microsoft.Office.Interop.Outlook, Version=12.0.0.0, Culture-neutrl, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.Presumably because on Windows 2000 the assembly folder is C:WINNT.I cannot work out how to target the WINNT folder for my references.
View 9 RepliesThe end result I am looking for is I want to add File Paths to a CheckedListBox. I only want certain file extensions and if a file by the same name but a specific extension exsists allready then I do not want to add those files to the CheckedListBox.
Example: I am only wanting these filetypes in my CheckedListBox (.gif, .tif, .bmp, and .jpg).However if the filetype (.PNG) allready exsists with the same filename (i.e. image. png and image.jpg) I then do NOT want to add that JPG. Only files that do not allready have a PNG with the same name. (I hope I was able to make this clear)
My current code will add the filetypes (.gif, .tif, .bmp and .jpg) to the CheckedListBox. However I do not know how to have the code only add the files that don't have the PNG.Here is my current code:[code].....
I designed an app that basically gets paths to servers I have admin rights to, I am doing such things such as checking available space on the servers etc., the problem I am having is my app only works if I manually login via something like (start, run, \server) and supply my admin username and password just to store that authentication.How do I code this so it prompts the user in my program ONE time for all 5 servers (they all use the same username and password)

I've been trying to wrap my head around using the registry, but I have to say I'm a little lost. Is there a way I can use a "path structure" to write to a specific key, rather than using it as a dim and storing it in memory?

I am preparing a project for distribution, and I need advice as to how to establish my paths to some of the dynamic data elements; sound clips, external imagery and a database.I am reading the environment.startuppath, but it's pointing all the way in to the debug folder, whixh I'm sure I'm not going to be using when I publish things for distribution.I was hoping for something that could establish a relative base folder, and then just reference a few subfolders from there.
View 14 RepliesI wrote an application that shows about 2000 GPS track segments on a map (ATV trails in Quebec). The user may select and zoom an area of the map, then print a detailed map that includes the GPS tracks:
When I print the map, I use the full resulution of the printer, so a 8.5x11 lanscape page on a laser printer generates a 6260 x 4800 bitmap. If I preview or print the entire page WITHOUT showing the GPS tracks, it appears / prints within 5-10 seconds.
When I include the GPS tracks, the preview is very fast (5-10 seconds) but the actual printing now takes over 10-12 MINUTES! I fail to see why the printing becomes SO SLOW when I include my GPS tracks.
My map only includes 3 graphics path, which were defined only once at the maximum zoom level:
- One RED path that includes all the tracks valid all year long (AnnualPath)
- One GREEN path that includes all the summer tracks (SummerPath)
- One BLUE path that includes all the winter tracks (WinterPath)
The printing is slow only when I add the 3 graphicspath to my printing output and looks like this:
' e = Drawing buffer of the Print function Factor = adjustment factor between the zoom level used when the graphicspath were defined and the actual printing zoom level
' HorzOffset = Horizontal adjustment to align the graphicspath with the output buffer VertOffset = Vertical adjustment to align the graphicspath with the output buffer
[Code]...
Anyone has an idea why adding a graphicspath to a printed page drastically slow it down? What should I do to imprime the printing speed? I have been baging my head on my monitor for the past week and I fail to see how I can fix that problem.
I have this code for drawing a path.
Dim map As New Bitmap(l1.Size.Width, l1.Size.Height, l1.CreateGraphics)
Dim nextPoint As Point
Using g As Drawing.Graphics = Graphics.FromImage(map)
Dim dPath As New Drawing2D.GraphicsPath
For i As Integer = 0 To path.Count - 1
[Code] .....
l1 is a Label. When I call this it draws the path fine, but when I call it again it draws another path but doesn't get rid of the first path. Basically, I only want one path on the Label at a time.
I'm working on a project right now that I've had my head wrapped around for about the last week or so. Without getting fully into it, it's a 2 part application. DoIT and DoER. DoIT creates commands that another computer, running DoER, is supposed to do.

We have a multilingual site, or culture-sensitive, and some of the static content now needs to be targeted; for this I'm using themes as it seems the easiest way to achieve what I want, but I can't for the life of me get the images to pick up.I'm setting the theme in code-behind, and thought at first that maybe this was the issue, but on checking up it looks like I'm doing the right thing (setting on Pre-Init).I expect to be able to reference images using relative paths where App_Themes/ThemeName/ is automatically resolved, such as:[code]In the above code, CurrentSite. Culture Name would be a language culture name (for example, en-gb, or nn-no) that does have an existing corresponding theme folder containing all required resources.Pages do have EnableTheming set to True. Also, I have tried removing the theme-setting code and applying the theme in the page using Theme="en-gb" to no avail.Is there anything immediately evident as to why the URLs aren't resolved?
View 1 RepliesI have a problem with my code. My code is using the fileupload control to browse for a filename when you add a filename it processes it and the code runs fine on when it lives on local host, but when I put the code on our prodution server it cannot find the filenames listed by user.
For example if I use the upload control to browse to B:MISCH IntiveRPTTOFL_3.csv and the code lives on my localhost which know what that file path means it works, but if the code is moved to a production server it may or maynot know what B:/ is or B:/ maybe mapped to something else. Even if I am browsing to a file on my C drive it will work on if the code is on the machine that the C drive is on, but it will not work if the code is on another machine because obviously that file wouldnt be on that C drive.

I want to check if two directories are pointing to the same place. Of course string based compare can be done easy but I also want to check for the situation in which a mapping points to the same location. Hence if m:dataapplicApicturesjpg n:applicApicturesjpg point to the same location it must be flagged. I have already searched I know there is something like GetFileInformationByHandle but I don't want to create a file, so I have not got a handle.
