View 1 RepliesHere are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?
how I can implement my calendar with VB .net express 2008 and MSSQL 2008 Express. How do I get it to work with datasets, binding source etc.If I go to Properties>settings my connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|CalendarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
and I have a table with fields:-
CalendarID
Subject

I can Add the event to the calendar I have the necessary items on my form linked to my table and I can save them to my table:
Me.Validate()

But I cant keep the event displayed on my calendar when I close it and open it again.
I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
View 1 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Each of the three components are loaded into an array. how can i call the buttons it i am unsure of the name. Possible answer could include using sender, addhandler.

I was wondering if anyone knows of any way of statically linking all dependant DLL's to the vb.net program? I know there are ways to find the dependencies using dependency walker and other tools like that. But was curious since c++ supports the static ability to load DLL's. If not, what tools can i use to quickly package the required DLL's without having to install .net on all my systems?

View 1 RepliesI currently have my cute little first program made... I'm just stepping into the water with this programming thing. I made a program where you can select a shape from a drop-down list and then input some values and click a button and get the area of the shape. I have it working so that when a certain shape is chosen, certain fields are disabled, such as when you pick "circle" from the combo box, the "length", "width", and "number of sides" text boxes are disabled but the "radius" text box is enabled, thus allowing you to enter the radius and find the area. I want to make it so that when you first load the program, all of the text boxes for the length, width, number of sides and radius are disabled until you select a shape from the list. Currently I'm using
[Code]...
This works for disabling the correct boxes when something is selected, but I don't know if I'm even on the right path with that first part.
I was observing my programs process in the task manager and noticed each action made to the program made the memory continue to rise. So I added a Garbage Collector and since it's my first time using it im not sure if I implemented it right. I haven't gotten any errors but I ran some tests I would like to go over with everyone. After adding the GC I was able to notice a change in the memory my program used- it was reduced.I added the GC to the main forms formClosed event of my application which is used in different scenarios. I also added it to the panels paint events before I tested the program. And noticed a quicker reduction in memory. The Form i mainly use called frmLine1t5. This form calls to the database based on which line to test. Then the form sets the controls that were added in design view to be enabled or disabled based upon the product for that line. This process was easy to implement.I Load each new frmLine1t5 to a collection of the form so people can run multiple tests using the same form. This helped so i didn't have multiple forms for the same type of process. I had to access the forms through a collection so I knew which controls to populate to the correct instance.
I noticed during my testing that I can not add more than 50 items to this collection. The problem is that I remove the key from the collection upon form closing, so I dont know why it has gotten to 50.The test I made Runs two timers. Timer 1 is set to tick every 4.5 seconds This timer loads a new form and tests a new line of product.Timer 2 ticks every 5 seconds and closes the previously opened form.I have it get the GC Total Memory upon loading the form of frmLine1t5 and upon closing the form of frmLine1t5.the results are shown in the picturesThe errors i have gotten occured when ChildForms Open: had reached 50Here are the errors:
[code]...
Possible Causes:I think that upon Form Closing it is taking longer to finish closing before a new form is loaded... But isn't vb.net suppose to finish any unfinished threads? Even if the program is single threaded?And because the form closing isn't "happening" then the key is not removed from the collection.
I want to refactor my existing application to work with as a client/server app, and was looking at introductions to Remoting.I got a simple system up and running 2 days ago, and haven't touched it since until just now, but now I'm getting an error message when trying to instantiate a class from the remoted DLL : "No connection could be made because the target machine actively refused it".The server and client are both actually running on the same machine for simplicity at the moment. I have three "applications" involved - a class library containing the server functionality, a listener application sitting with the server, and then a client applicaition.Most of the articles I can find online referring to this error seem to apply primarily to asp.net but I'm just using traditional vb.net (2008)I initially suspected the cause may be firewall related (as when I first got it running I was prompted to allow access) but I've turned off my McAfee firewall and also my Windows firewall with no joy, and besides - the error message seems to imply that communication with the server has been established but that it doesn't want to play ball.
