I am making an application that prints records and I want to set the paper height dynamically. My problem is how to change the settings of the printer programmatically in VB.Net.
Somebody told me that it could be done by going to Device and Printers, select the printer and setting it with the desired height. However, can I do this programmatically?

View 2 RepliesI am writing a program to automatically switch my proxy address based on the network I am connected to.
I have so far got everything to work except the part that I have highlighted below.
Is there any way to change the automatic configuration script and the automatically detect settings in code?
The solution can be either P/Invoke registry editing. I just need something that works.
We have a VBScript that launches an Access app that connects via ODBC to SQL Server - wouldn't you know the server name is changing.
Is it possible to use VBScript to modify the ODBC information in the registry to point to the new server? Basically changing one specific value for one specific key. Am I better off deleteing the ODBC key and readding it from scratch?
I couldn't find an appropriate forum which would suit the type of problem I am facing so I am putting it here.I needed to create an intranet web application that has pages with hyperlinks to eml files. The eml files as is known are email files in MIME format which outlook express can open. However what I found was if eml files are on your machine, it opens in outlook express but when opened as an hyperlink, it opens in Internet Explorer (IE) as an mhtml file. And any attachments that may be in the eml file are not displayed at all!I didn't understand why IE has to poke inbetween. After searching the net, I came across a solution that required changes in the Registry of the client machine.The change is to be made to the node HKEY_CLASSES_ROOTMIMEDatabaseContent Typemessage/rfc822.The following is a REG file that can be imported for this change.[HKEY_CLASSES_ROOTMIMEDatabaseContent ypemessage/rfc822]"extension"=".eml""CLSID"=""However after this change, though eml files opened in Outlook express, MHT files stopped opening in IE.Then I simply deleted the rfc822 node and to my surprise, MHT files opened in IE and eml files opened in outlook express and everything was fine!!But I don't want to use this sledge hammer solution. I want to know what this registry key is for and how can I set it to achieve what I want . i.e. open eml files from web pages in outlook express without affecting other file types
View 8 RepliesI am rewritting my application to conform to ms standards. We used to save all settings to registry for user settings, servername, size and locations.so we are now saving them into My.Settings app.config the only problem is that each time there is an update clickonce will isntall the newupdate but now all settings are loist and user has to save everything all over again..
I am trying to follow the book here but it seems i keep getting stuck somewhere. registry has worked fine for years but i understand we must move on, but if stuff like this happens then i just wasted a long time converting all code to conform for it to not work..

I want to check the Registry Permission of Subkey programmatically.Whether the Subkey has Read permission,Write Permssion, Delete Permssion.
View 1 RepliesIt saves the settings to the registry, loads the preset settings, and if you want to uninstall the app, you can use the delete settings, which deletes the registry folder for you app.
Here's how:

If you edit a service in Windows 7 and go to the Log On Tab, there is an option to "Allow service to interact with desktop". I'm trying to ensure that it is set for a certain service using VB.NET.
Note: Doing this during the install of a program is not an option. It has to be done at run time.

View 1 RepliesI would be grateful if you helped me. I've built a text editing application and I would like it to load values/user settings from the Windows Registry. Here's my code but it is somehow wrong (I believe it whatsoever has to do with wrong syntax but it could be something else);

I want to read 'File.ini' line by line checking if specific text exists in the file and then display on a windows form weather particular settings are turned on or off.So far this code works if "TargetText" exists but if it doenst I get an error on the code line: "If line.Contains("TargetText") Then".
Code:
Using z As System.IO.StreamReader = New System.IO.StreamReader(File.ini")
Dim line As String
' Read first line.

It works if "TargetText" exists in a line in the file but if it doesnt exist I get the 'Null Reference Exception. Object reference not set to an instance of an object.'

If I'm not mistaken, the code will not continue in the Try block if the first part fails and then move on to the catch statement, correct? I'm adding and deleting a bunch of different entries in the registry and the computers I've tried my app on so far, have not failed. So I'm not able to test if this method will work for error catching. If there's a better method, I'd appreciate the info.
Why does my app not load the saved user scope my.settings when it starts by way of the registry run key? This key starts programs after the user login, per microsoft. So why does it not load the saved user settings? The program does start up, but all the areas on the form where saved user scope settings should be, are the default values (mostly empty strings). (The user scope settings are there if I start my program by the desktop shortcut
I've looked, searched, posted to other forums, but can't seem to find an answer.
I'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?
Code:
Option Explicit On

I have an application that I need to be able to read and save a bunch of registry settings before they are changed.

I know similar questions have been asked/answered, but after looking across the net for 2 days I still haven't really seen an answer to the following question.rst, background info: My application starts at windows start as a user checkbox option (by using the run key in the registry.) I don't know if it is usual or not, but when the app auto starts on windows start, no saved user settings show up on the form (but they do when starting the program manually after windows is already running). I've tried both HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE. In case anyone needs or wants it, my code for accessing the registry is:
Dim Reg As Object
Reg = CreateObject("Wscript.shell")
Reg.RegWrite("HKEY_CURRENT_USERSOFTWAREMICROSOFTWINDOWSCURRENTVERSIONRUN" &

I was wondering if it is possible to change the Proxy settings("Automatically Detect Settings") in IE without making the change to the registry. I wasn't sure if the Hive is similar in all operating systems, So I figured there has to be an API to make the change, also without having the restart the IE or the computer for that matter.
