View 6 RepliesI have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....

View 1 RepliesSPECS: Visual Basic 2008 - SP1/2, Framework 3.0.3.5, Windows XP Pro, SP3? trying to wright code for checking for existing files but what has me stumped is the (WHAT IF PART) of it witch in fact is what I want to see. What im saying is can I find a file without knowing where it is on all drives? Or how can i find a folder if I dont know where they installed it to.
Example: I know that C:Perfect World International <--- is the default location where my game installs but what if I installed it on D:Perfect World International; or rather on drive G or H. How would I test to see if it exist without making a bunch of nested If statements to test every drive for it.
this also applies to files like: D:Perfect World EntertainmentPerfect World Internationalelementelementclient.exe is there a way to find these files to see if they exist. I know that Perfect world international does not use the program files to put there program files in as you see above. so Envirnment variables I think cant be used correct me if I'm wrong. BUT I know the registry of a computer keeps some stord information as to where these applications are installed to like (References App Data).
What I'm trying to do is use this to tell the user in a Label that the game is installed in this path but I know in some circumstances the game is not installed on drive C: or D: or even in this directory some users can install it in there own directory such as C:PWI. and as such the file elementclient.exe can even be in C:PWIelementclient.exe. So to sum it all up can this be found useing some sort of code to find the file and folder and return them both in 2 difrent labels like this
Game Is Installed In: C:Perfect World International
Game Client Name: elementclient.exe, C:Perfect World Internationalelement
Game Found On Drive: C:
ETC.
I'm thinking and keep thinking that this can be done in many ways but as for environment variables I'm stumped. But perhaps windows registry may play a role in doing this but I myself don't even know where this stuff may be found; and even more how to apply it to code.
I'm in need of a way to find the original path of a substituted (Virtual) drive, set with the subst command.
Start -> Run -> type "cmd"
[code]
subst l: c:\scripts
[\code]
This create a virtual drive that points to c:\scripts\
in .net an easy way to get all the drives on the computer is using the Drive property of My.Computer.FileSystem. However, this will give you the current substitued name of the drive. Is there a way to find the original path?
I get the path of the virtual drives mapped to network folders using WNetGetConnectionA of mpr.dll, However, this only resolves mapped network drives.
I currently don't have away to find the original path of LOCAL virtual drives.
Having difficulty with the module below failing on line 21. It is telling me: The system cannot find the file specified. (Exception from HRESULT: 0x80070002) Basically what it is designed to do is look for a directory, if that exists then look for a file in that directory. If both = True then it should open the folder to browse the files. I believe the issue is with the "Program Files" being 2 words since the script runs using a root path, but I'm not sure how to format the path correctly to make it work?
