How to save this button so that when the program runs again, it's still there?
I want to place a few buttons on my form. The number is unknown at design time. Actually each button will represent an item entered in combo box. So if user adds an item, a button on the form should be added by the code.

i have created dynamic buttons at runtime and i would like to disable them when a user clicks on a form button.This is the code i have for that button:
Dim intXX As Integer = 0
Do Until intXX = intX
userAvatar(intXX).Enabled = False
intXX = intXX + 1
Loop
The buttonNames is an array of all populated button names created at runtime. However, trying the .enabled = false at the end of that does not work. What other ways are there to do that with buttons created at runtime?

View 5 RepliesWhen I set the button background image in properties, it looks great. When the button is clicked, the image needs to change. I tried to use an image list like this: btnSample.BackgroundImage = ImlStimuli.Images.Item(0)and I tried loading them from a file. I can get them to read, but the image always turns out blurry or distorted. I've tried all variations of alignment, BackgroundImageLayout like stretch/zoom/centered, and I changed flat style, but nothing has worked. Is there a setting or something that I'm missing in properties?
View 4 RepliesJust a quick question, using Visual Basic 2008, is there a way to change the text of a forms buttons and other objects during runtime so that the text sticks no matter if the form is closed and reopened or not? I can get the text to change, but after closing the window and reopening, the text resets. Is this possible?

[Code]...
the buttons will be created according to a variable that changes during runtime, so I won't know the names of the buttons.
i know is there any simpler ways of coding to enable the user to drag and drop button and this button will toggle the background color when the condition is true. So which means to say i need to know where can i place the main program code in the code block.There will also be a provision for the user to delete the button control at runtime.
View 2 RepliesI have been playing around with Visual Basic for about a week now. I created a program that I use at work basically just to organize my day.
The program consists of buttons that link to programs and spreadsheets that I use often, as well as a checklist of tasks I've completed and text boxes that I use for reminders. Other buttons affect GroupBox texts and Label texts.
What I'd like to know is how I can implement a Save and Load button? I'd the current state of the program to be saved so it can be loaded in the event that I have to shut the program down. (Check boxes checked, Text in Text boxes, Labels, etc...)
I've been looking online for HOURS and I've messed around with the SaveSettings feature... nothing seems to work.

When you complete various feats in my program, on a form called "User Details" there is a label with the text that says "Complete" only when you have completed a particular game. There is a save button, and a load button, all on different forms. How could I make a save and load feature? One that saves the fact you've completed certain games - and then when you press load after exiting and reentering the program, the Complete text will reappear.

I 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 2 RepliesI'm working with a 3rd party assembly to implement something in our in-house software. I can make the refence and work with the library without a problem, but when I run the program to test it i'm getting this error "Can't load file or assembly "assembly file" nor either of its dependencies. The system couldn't find the specified file" (i'm from Mexico, exception is in Spanish so i had to tanslate it, sorry for the poor translation) I have given read and write permission to the file, the folder, and for all users and still wont load it. I saw that the assembly has the PublicKeyToken=null, does that have any to do with that i cant load the assembly?

View 2 RepliesI am creating a test project using IBM's Rational Functional Tester(RFT) tool(we are using the VB version of it and it only supports till .net 3.5).In this project I am making all database queries using the entity framework.The problem is entity framework retrieves "Metadata", "Connection String" etc from the App.Config file,and RFT won't let me add a App.Config to the project(I guess it is designed that way -- I googled adding an App.Config file to an rft project and came up with nothing), and the Entity Framework requires you to have the app.config file at the entry point.I was building the string to pass to entity framework in code, but my boss really does not like that. So looking at my options I think any of the below 2 solutions should suffice
Is their any way to load an App.Config during run-time. Is their any way to add an App.Config to an RFT project(should really be my first question).

I am working on a project where I have to load assemblies (lets call them tasks) at runtime, run the task and then be able to kill off the whole assembly so that the dll can be replaced without interrupting the main application.There are many of these tasks running within the main application,some run sequentially and some run in parallel.Occasionally one or to of these tasks need to be updated and then re-added to the queue. Currently we are stopping the entire application and interrupting the other tasks at whatever stage they are at, which is not ideal.I have figured out that I will have to load each assembly into a separate AppDomain, but loading the assemblies in those domains is proving difficult, especially when I need to actually run the tasks and receive events from them.I have been looking into this problem for a couple of days and have still not managed to get a working proof-of-concept.
I have an Interface for the tasks which includes a 'run' and 'kill' method (subs) and a 'taskstep','complete' and 'killed' event.'taskstep' returns an object to be cached later, 'complete' fires when the whole task is done and 'killed' fires when it is ready to be unloaded.There should also be a timeout on the whole process of two hours and a timeout of 2 minutes on the killed event in case it gets stuck, at which point I would like to be able to unload it, forcing any threads to terminate (which is what 'kill' should do anyway).Each assembly may contain several tasks, all of which should loadable be unloadable.I have no problems loading these tasks as 'plugins' but am lost when trying to both use them and unload them. If I have to create some elaborate wrapper then so be it but is what I need even possible? I have tried inheriting from MarshalByRefObject but I do not even know the assembly fullname unless I load it first, which then locks the file. I have tried loading from a byte array of the assembly. This means that the file is not locked but a copy of it remains in the current appdomain. This will become problematic over the following months / years![code]
I apologize if this is a rudimentry question, but I have an application that makes several calls to several .dll's. I notice that the first time the function is called, it seems to take a very long time (about 10 seconds) for the functions to complete.
View 2 RepliesI have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event.

But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.

Not sure if this is the correct place for this postWhat I am trying to do is update dll's in my application.Using VB with dotnet 2 (Visual Studio 2010)The Project has a number of Dll's one of each department i.e. Sales is sales.dll... Development is development.dll etc....Each dll has classes/User controls which is used and dispose depending on the section within the application.Once work has been completed with a dll, it put in the deployment area, currently another is program launching checks the file verison and updates as required, before the main application lauches, this works. The exe hasn't needed updated for a long time as all the changes are in the dlls.
What i have been looking at is update method for the dll's dymanically, when not in use, when the dll called into use or disposed of.I have looking at LoadLibrary/FreeLibrary and application.domain. I have been reading loads and tried out some of the examples, with a modified to suit. I am just not getting it.
