View 7 RepliesOk I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.

I am attempting to add code to an existing script that will add the log messages to the log txt file in order to determine which loops are running in the script. But all I get is either a blank log file or only one line which I believe is the last loop that ran and not a concatination of the loops that ran which I know is more than one.
How do I create a log file that will continualy grow?
These log calls are placed in each of my loops (I am just showing 2 as an example.)
log ("in loop 1")

I am a beginner in vb 10 (vb.net). I am trying to create a text file "something.txt" and write a long string to the file. My string contains formatting chars newline and carriage return, which I want to keep.
I tried:
FileToSave.Write("test" & Chr(10) & Chr(13) & "test2", RichTextBoxStreamType.RichText)
using the System.IO.StreamWriter method but the line feeds and carriage returns are lost and all the text is just streamed together with no formatting.
Where 'FileToSave' is the path and name of the file. Note: I know I can use the vbnewline instead of chr(x) but this is not the issue.

I recently started having problems when creating new schema (xsd) files inside Visual Studio 2008. When I create a new schema file, the only file that is created is the xsd file itself. Neither the designer.vb or xsc files are created, which of course makes it unusable. The problem seems to be caused by the fact that the CustomTool property in the property grid is missing. If I change the CustomTool property to MSDataSetGenerator, then it immediately runs and creates the missing files noted above. How do I reassociate the CustomTool with Schema files?
