View 1 RepliesI would like to create a filepath and assign it to a string (so that it can have yet more added to it later on in my program) the code takes (well i want it to but it doesn't) the name of a drive selected previously and then adds this to a string to create a string variable that refers to a file. and then (as usual) i want to use thes files and display them in a combobox but i want to only select files that have a pre selected 2characters at the front. I have got this code so far:

Has you can see I had to use progra~1 instead of Program Files.[code]

I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf"
Dim FilePath As String = MapPath("../Document/123.pdf")
Response.WriteFile(FilePath)
Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.
I'm using acrobat that returns unix paths instead of windows path's. So im wondering if there is a way in vb.net to convert the path to windows path.
i tried using:
docs(i) = javaScriptObj.path().ToString.Replace("/", "").Substring(1)
position = docs(i).IndexOf("")
docs(i) = docs(i).Substring(0, position) + ":" + docs(i).Substring(position + 1)
this only works on local files, but fails when im starting to use network drives.
I am trying to allow my VB.NET EXE to have a variable defined by the run command. The problem is I have no idea what the terminology would be for this type of run.
For example - the shortcut is set to do "myexe.exe debug" This would set a variable to "debug" which on execution my app knows to enable a debug mode.I've done it in batch scripts before - it just enables the "%1" variable or "%2" based on the location (e.g. test.bat hello world - hello would be %1 and world would be %2).Hopefully I explained it well. I tried searching for "variable in execution path" and "variable on execution" with other mixes, but none of those searches return what I am looking for.
I can't seem to get this to work. I am just a novice plugger and do some of these forms for my work occasionally. I am assigning a textbox result to a variable. I then want to use that variable in a path string i.e. ("c:some stuffvarname") but the variable looses focus once placed inside the quotes.

How can I create a DLL declare statement with an environmental variable in it so as to make sure that I'm loading the system DLL from the right place, the system32 folder? For instance...
Declare Function GetExtendedTcpTable Lib "iphlpapi.dll" Alias "GetExtendedTcpTable" (ByVal tcpTable As IntPtr, ByRef tcpTableLength As Integer, ByVal sort As Boolean, ByVal ipVersion As Integer, ByVal tcpTableType As TcpTableType, ByVal reserved As Integer) As UInteger
The reason I'm asking is that there has been talk about people injecting invalid/malicious DLLs into folders along with applications and whatnot and I see this as an issue if you don't specify the SYSTEM directory. Yeah, I could specify it to load from c:windowssystem32 but what happens if a person doesn't have their Windows installed in c:windows? Hence the reason to use an environmental variable to find system32.
When im naming a variable for a directory should i end the variable name with path, folder or directory.
