View 1 RepliesI'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
If ListBox1.SelectedItem.ToString > 0 Then 'LOADING THE INFO CODE... 'SAVING... 'create: My.Settings.(ListBox1.SelectedItem.ToString & "1") = Label3.text 'create: My.Settings.(ListBox1.SelectedItem.ToString & "2") = Label5.textEnd If

I'm designing a rather specific form in VB.Net 2008 Professional Edition for my company per a PDF file I have been provided. I just noticed that everything seems to shift at runtime... The change is drastic enough that the blank space is displeasing to the eye and doesn't match my predefined form.

I 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?
VB.Net 2008 I have a problem when loading dlls.Such that I have a dll which contains a class like:

View 4 RepliesI 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 RepliesI'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.

View 4 RepliesFor debugging purposes, is it possible to get the value of Option Compare at runtime?
(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.)
I have 9 tables with state information in them. They all have the same field names. I have a Crystal Report that is based on one of them. I want the user to be able to select a state and change the Crystal Report to use that table instead of the one it was based on.I mean when user select text in combo box and then click on "OK" then report show (using only one rpt for all the tables of same fields).
View 2 RepliesI'm writing an application for a device running Windows XP. There are 2 versions of the device and each version has its own API to communicate with the device's software. The application I'm writing needs to pull the same data from the API. My question is how to write a application that will detect at runtime which version of the device it is on and use the appropriate API.
I've created an interface containing all of the common methods and also classes for each device that implement the interface. Now I need to know how to activate the correct one at runtime.
Public Interface IAPI
Sub InitializeMachine()
Function GetActiveProgram() As String

View 3 Replies"add controls at runtime" how to add code to the controls. kinda useless with no code, ehh? all results only told me how to add the control, that's it. well, this result is different. i will teach you firstly how to add controls at runtime, then how to apply code to them at runtime
Firstly, add the controls:
[CODE]..............
Now run it. do you have a button on the form? if yes, excellent. if not, you made a mistake. try again now how to add code? you may have noticed that when you double click on any control, it says private sub button1_click(blah, blah, blah) Handles button1.click where it says handles button1.click is what determines when the code executes under what event for what control (in this case the click event for the button1). this won't work when adding code at runtime. did you notice in the above example i added a with event, and addHandler? this is what creates the handler (same as Handles button1.click)
Now we add the code for the runtime control
[CODE].........
Above, the addressOf button1_click tells the program to execute the sub button1_click when the button is clicked on (as determined by .click) but i know what you're thinking! your thinking "why would we even BOTHER doing this at runtime? isn't it easier to do it at design-time in the first place?" yes it is, providing your not writing a plugin. plugins are code based, not GUI (also reffered to as WYSIWYG). to update existing forms using plugins, you need to use this method.
