May 24, 2012I'm creating an app to manage the movies I've watched and get some info about these movies and then display these info in labels.At moment I'm trying to load the "runtime" and "genre" into label3 (runtime) and label5 (genre). Once the movie name is clicked in the listbox control, these info are loaded from a website (webbrowser control) and then displayed in the labels. My question is: Is there any way to make the My.Settings save these info for EACH movie? Something like this:
Saving the info:
vb

How To Import DLL During Runtime
Mar 11, 2009I made DLL files using VB and placed them in the same directory as .exe. When I edit the source code for .exe and type Dim obj as Object obj = new DLLname.DLLclass everything works fine. The problem comes when I try to use Dim obj as Object obj = CreateObject("DLLname.DLLclass")'error line and an error "Cannot create ActiveX component." is produced. The second code block is more useful to me because I don't want to explicitly specify the name of each DLL file in the code, but rather handle the names as string variables.
So basically I need to import DLL's on the run - how can I do that?

View 4 RepliesLoad Mdb At Runtime?
Nov 23, 2009I am working on an application which will be used to read/write/provide custom functionality using an mdb file. I have been able to create the program, and access my test mdb file just fine using the normal ado connection protocols. The final product will be used in an application/file format where each user will have thier own mdb file, and multiple users will be using the same application on the same computer to access their files. I need to figure out how to load the mdb file at runtime using both an open file dialog, and to be able to double-click the file in windows and have the applicaiton open and load the db that way (I know how to create file associaitons, it is just the databinding that I am having issues with- and the mdb file uses it's own filetype, so I won't step on the toes of MSACCESS).
View 8 RepliesLoading And Using A DLL At Runtime?
Sep 28, 2009I'm trying to make my program have plugins that don't require real installation. My plan is to have the plugin consist of two files:a dll file, and a xml file describing the dll so the program knows what to do with the dll. However, I have NO idea where to start.I've referenced dlls and used them in my program before, but that was BEFORE compileing the program. Could someone please point me in the right direction? I am using Visual Basic in Visual Studio 2008 Professional.

(I am working on a legacy Windows Forms application that uses InStr with the first parameter as String (three parameter version of Instr), without the third parameter that is then determined by Option Compare. Option Compare Text supposedly makes InStr case-insensitive; the default is Option Compare Binary.)
