Driver Detection - Tell User That It Is Safe To Close Program Once Driver Is Install
Jun 1, 2011Trying to figure out if there is anyway built into windows 7/Vista/XP and/or Dpinst to verify that a driver is installed? I created a program that uses DPinst to install a driver and now I need to figure out how to tell the user that it is safe to close the program once the driver is install as the driver takes longer on some machines to install. Would anyone know how to get this to work?
View 7 RepliesUsing This Link For Reference?
Jul 28, 2010Just wanted to make sure of something. Using this link for reference, in VB6, thesevariable declarations are equivalent:Private m_bFlag As BooleanDim lLoadedRecords As LongSo I could rewrite them in VB.NET asPrivate m_bFlag As BooleanPrivate lLoadedRecords As Longand they would behave the same way? I don't know why the VB6 programmer wasinconsistent, which is making me doubt myself. I'd like to change it for consistency but not screw up anything he was intentionally doing (code is 10 years old and I am converting it.)

Getting Information In A ComboBox And Reference To A Database?
Jan 20, 2011I have a problem getting the right information to a ComboBox.I have a table in SQL Server that contains a list of names.I want to get those names to appear in my ComboBoxes shown in the picture. (DONE)I also want the list of names to decrease by the names already used in other ComboBoxes in that Form...
EXAMPLE:So, lets say I have a list:
Name_1
Name_2
Name_3
[code]....
In the Form, there are 10 ComboBoxes.I choose the Name_1 for ComboBox1, Name_2 for ComboBox2 and Name_3 for ComboBox3.The options available for all other ComboBoxes should be Name_4 ... Name_6.If all of the 6 names are filled, the rest of the ComboBoxes should have no option to insert into them...
C# :: Reference Configuration Information From Within Multiple Class Libraries?
Mar 13, 2009I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?

View 3 RepliesCall An ASP Link From VB Code-behind Instead Of User Clicking Link?
Feb 8, 2012I have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes
Feb 2, 2011I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _

In fact I don't want the user to have to do anything at all except request to view the document which will set the automatic process in motion.
