View 1 RepliesI have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.

Do you have a sweet solution in VB (visual studio 2008) to read an OWL file and display nodes on a treeview? It works great for XML but not for OWL when nodes are like as follow: [Code]
View 2 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'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:

I have created some desktop applications for my portfolio, but now I want to create a Point of Sales (POS) system to add to the list.I notice in supermarkets and various shops that POS systems use touch screen monitors to interact with the program.My first question is, do I need to use different code or controls in my applications so they can be used with touch screen monitors.I have created an application for hotels for booking rooms (not for a client, just as a demo project), but if there is anyone out there who could give me some pointers on how to create the POS system.I will be doing some research and I will start designing some controls over the next few days. I am looking forward to getting this project started.

View 10 RepliesI have a program that I have gotten as far as programming it to inform the user of updates, have them push a button to download it. The updated version of the exe will be downloaded into a subfolder called "Updates", where there is a program called "Updater.exe"This program is one form, with a progress bar and informs the user the program is being updated. Every time I run through it step by step it appears to work, but in a real environment the program stalls out. It doesn't crash, but the bar continues to move with no action being taken. I can not help but wonder what on earth must be going on in the code, which you can see is quite sloppy and rather unweildy:[code]And there is of course the issue of not being able to change data on the hard drive without administrator privileges as is being discussed here: url... When I finally get a manifest working for this program to require administrator access....how could that screw up this updating process...How can I better perform this, what seems to me, simple process of deleting the old file and replacing it with the update?

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.
