I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.

View 1 RepliesI have a WinForms application that I have taken over support for and it was build using Visual Studio 2005 with VB.Net. The application makes use of an Access database. It runs fine when it is installed as a standalone application, but the install cd for the application also allows for a network install and this is where I am currently encountering issues.
To test the network install I created a folder on my server (Windows Server 2003 SP2) and copied the Access database to this folder. I created a share for this folder and gave everyone full permissions to the share. Then on the workstation I installed the application and gave the path to the database as follows:
\myservermysharemydb.mdb
(The install steps here are as per the instructions given on the installation cd)The workstation that I installed it on is Windows 7 Ultimate. When I run the application, I get the error message given in the title when the application tries to read the database file. I have confirmed that I am able to write to the shared folder on the server, so I don't think this is a permissions issue. Also, the database file is not in use at all, so it is definitely not opened exclusively.
UPDATE:I have tested the workstation installation on a computer with a fresh install of Windows XP SP3 and it is able to access the database file without a problem. So it seems that this error that I am getting is somehow specific to Windows 7. Is there maybe a known issue with Oledb drivers on Windows 7? My version of Windows 7, btw is 32 bit.
This is a simple fragment of my code:

The last line throws an exception "Cannot open file" with certain end-user profiles. It works perfectly fine when executing from an Admin account. I just cannot figure out what user privileges and access settings may cause the error. Note that it also works with some end-user accounts (not admins). What missing user rights can cause this?
I have a project that will add the conents of a .txt file to a listbox but how would I make the program to open a browse for file dialog when a user click a button and then add the file to something to be read from like:
Dim accpath As String = My.Computer.FileSystem.ReadAllText(System.IO.Directory.GetCurrentDirectory() + "\somefile.txt")
The specific features I want to produce is it doesn't place on the form, it places in the little box at the bottom and when CustomUserControl.Show() is called it shows as a dialog boxI'm sorry if I misspelled something or my grammar is wrong, I've never done well in those subjects.
View 1 RepliesHow do I open a particular html page in a chm file when the user clicks on a menu item.
View 2 RepliesI'm letting my users write their own HTML from my webpage. When they click the preview button, my code behind needs access to controls on the page (and so I understand I can't use a web method here). It builds the HTML and saves it as a file on the server. My question is: Once the file has been made, I want to automatically open the file in a new window for the user to see their handy work. I'm using vb.net, but happy to receive c# answers.

I've written a VB.NET program for a client that stores all of its data in XML files. I use the XMLReader to read the data into a dataset. When I run the sub to encrypt the XML file, I'll get the following message: Error: mscorlib: The requested operation cannot be performed on a file with a user-mapped section open.
It doesn't happen all the time, so I know it does work. But on occassion, I'll get this message. I've been all over the forums and I've tried everything I've read to try and stop this error.
I close the reader object and set it equal to Nothing. I've even tried using DoEvents to make sure the object finished closing before running the Encrypt sub. Nothing has helped.
I develop on a x32 PC. It works fine on the development machine. But then, when the client runs it on a x64 PC, he gets these errors. Could the x64 system really be running so fast that the .Close() and the = Nothing and evern the .DoEvents() can't keep up?
As part of a program for class we were instructed to create a text file on the user's computer. The instructions were to create the file to the C: (or the same drive as the Windows directory) but Windows7 requires Admin privileges to write to this directory. It works great if I run Visual Studio as admin, but I'd rather just write to an unrestricted area. For example the desktop. Is there a way to write directly to the user's desktop without knowing the user's username. Right now I'm using this "c:UsersNickDesktopScores.txt"; which works but of course the user's name is different on every machine. How would I go about specifying the user's desktop?

I have an application that I'm writing that needs to allow the user to be able to create templates and save them for how the applicaton will work. For instance, lets say I am provisioining mobile devices, and my application allows the user to create a template to only install "application1" on the device, with "application1" settings for "devicetype1". But then if the user has "devicetype2", he or she can select the template that they created to install the software for that kind of device. I've looked around and all I find is the .exe.config for read only application settings, and I have found the user.config for the read/write variables. But that won't work as my application could have several templates depending on what the user chooses. I'm looking to have my app have a "create template", "edit existing template, and"use existing template" buttons, and have my config file extension like *.ipx for example.
