Adding "Properties" Dialogs - Pre-built Dialog Or Control For Displaying Properties At Runtime?
Nov 6, 2008I have my own class of graphic objects, and now I'd like to allow a user to right-click on one of those within the application and see a properties window. Is there a pre-built dialog or control for displaying properties at runtime? I'd like to have something just like the IDE properties window button for my application.

.net - Pass COM Array To Managed Code?
Apr 7, 2011I have a .Net application (VB in particular, although I would this to be as language agnostic as possible) that uses a COM object (made in C++). I need to implement a event in COM that passes a char array from C++ to .Net. I guess I need to convert the array to a managed array; How can I do this?
View 2 RepliesC++ Unmanaged Code Versus Managed .net?
Sep 19, 2010I am trying to develop a dll in VisualStudio2005 in vb.net that will communicate with a spectrometer attached to the USB port of the computer.Now the dll exists in C++ and it works like a charm. It is unmanaged code.Now if I try to translate this code in VB.net (because our app is in VB and my boss wants it in VB for maintainability) I have problems.
First of all, I am trying to create a file to open that port. The code in C++ looks like below and it works. Needles to say I tried to call the C++ dll from our app and it works. If I call the vb dll it doesn't. It gives me "access denied" no matter what I tried. I am not sure if my CreateFile is wrong or it's .net. I read somewhere that I need a manifest file included in the dll? Has anyone experience something like this? Why would i get "ACCESS DENIED" all the time?
// close and clear current stuff
ClosePort();

Calling Managed Code From Unmanaged C
May 30, 2012I need to write a DLL in C that is used a plugin for an existing application.The DLL has to be compiled by the Visual Studio 2008 compiler with the following options.[code]It's then linked to applications library's.What it actually needs to do and what's causing me the issues is that within one of the methods it needs to pull data from a sql server 2008 r2. From what I've seen today you wouldn't be able to do this directly in C as SQL Server past 2005 is designed to communicate with CLR languages( C#, C++, VB.Net).It was suggested that I handle all the database communication with a VB.Net dll and then call said function from within the C dll. Most of what I've found on the topic of calling managed dll's from unmanaged code has talked about pinvoke or com wrappers and mainly from the perspective of c++.

View 1 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.

Set The Transparent Property Via Label Properties Properties Not Via Code?
Jan 16, 2009I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()
End Sub

Displaying The Printers Custom Properties Dialog
Sep 19, 2010How do I get at and invoke the properties dialog supplied by the manufactured? I have search this many times and found that most of the posts contain solutions that the original poster claims don't work The standard PrintProperties class does not handle a lot of printers who have specifictsks, eg a printer designed to pint on the face odf CD/DVD. I have found examples of how do this in VB6, but every examply I find for the versions of VB Basic after thet have comments that the solution provided did not persist the user chnges. Bow, come on, there has to be a way of displaying and persisting the user choises the dialog bog provided by the printer manufacturer!Terry

View 3 RepliesApp Name Does Not Show Up In Open With... Dialog?
Jul 29, 2009After deploying and installing my application I use the app to create and save a file with my own file extension. After the file is created I right-click on the file and select Open With.. so that I can associate this file extension with my application. In the Open With dialog I use the Browse button to find my application and select it. In the Open With dialog the application icon is shown, but the name of the app is blank (looks like an empty string). Can anyone tell me why this might be happening? I've looked at the Registry, which shows the correct app, but every time I open the Open With dialog only the application icon is displayed, no name.
View 2 RepliesHow To Close And Re-open A Dialog
Sep 3, 2009I'm developing a WinForms app in VB.NET, that handles sets of style data, and when the user clicks on another set's label, it prompts through a dialog "You are leaving this style preset to edit another one. keep changes on this one? [Yes] [No]".But, I'm facing the problem that, when the user clicks either option, and the dialog closes, everything has to be refreshed, and loading the form again seems a good option.[code]But as soon as that sub is called from the prompt, it crashes the application. (doesn't show an error in debug, simply crashes) How should I, from a given dialog, close the dialog, it's parent, and re-open it's parent? (which triggers all the Dialog_Load() code of the parent)
